The London architectural studio «Two Create» has created a colorful interior for a new modern hospital of Queen Elizabeth in Birmingham.
The hospital interior looks rather cheerful and gives only positive emotions. Green apartments give more healthy happy life.
Design studio «RHE» has created unusual interior design for new branch of the lighting shop «Atrium» (London).
Throughout the Renaissance, the demand for antiques among the aristocracy burgeoned, with the trend soaring by the late 17th century as members of the upper classes began scouring Europe in search of bronzes, sculptures, prints, lamps and vases. With disposable income then rising among the aspiring middle classes in the latter part of the 19th century, the bourgeoisie took to investing in their homes and in the finer things as well. As antiques went mainstream, the market boomed in the hubs of London and Paris.
However, despite this generally rising appetite, antiques have a tendency to go in and out of fashion, as evidenced by the lulls in between the booms of the 1950s and 1980s. At present, the market is experiencing yet another lull; new tastes and values have sent demand and prices for antiques crashing, leaving armoires, bejewelled knick-knacks and Regency dining chairs unwanted and unsold, and causing many industry players to close down or change course entirely. Yet, in the midst of all the doom and gloom for antiques aficionados, there is some cause for optimism in a few niche areas, especially when it comes to fossils and minerals.
Out with the old
With so many more people living in smaller abodes these days – urban dwellers in particular – there is very little space for antique desks and looming tapestries. Nor, in fact, do such items match contemporary tastes, as interior design trends have changed considerably over the past decade or two. Sleek and modern pieces, airy spaces and overall functionality are the style du jour; cluttered rooms and bulky furniture seem to have little place in 21st century life.
“In general, young people have lost interest, and it is mostly older people who are buying – and obviously this area of the population is one that declines”, said Errol Fuller, a curator at Summers Place Auctions, and a leading expert on fossils and extinct species. “Not all areas of antique collecting are in retreat; it is the more drab brown furniture and traditional items that young people have little interest in. They look old-hat and boring.”
Given the niche knowledge and training required to even begin delving into the subject, Baby Boomers and Millennials are largely uninterested in antiques. Adding further to this growing indifference is the reputation antiques have for popularity among the older generations – a status consolidated by television programmes, such as the US and UK versions of Antiques Roadshow, that depict the field as a hobby for pensioners. The downsizing of former antiques hubs, such as London’s Fulham Road and New York’s Kentshire Gardens, reflects this shift further still, indicating the market in general has indeed reached a precarious state.
In with the even older
Over the past year or so, one big trend that is offering hope to those in the trade is the growing popularity of fossils and minerals.
“Decorative items, or things with intrinsic interest, still have appeal, and fossils and minerals have much of this quality. As do antique stuffed animals and birds. And it is these kind of things that are appealing to the young”, Fuller said. “The general public is becoming increasingly interested in the natural world – perhaps because we realise that much of it is vanishing at an alarming rate. We are becoming more conscious of anything to do with nature and to call a piece of natural history your own and to look after it for a few more years and save it for generations to come, is quite special.”
This interest in the natural can be seen across numerous sectors and industries: food, make-up and alternative therapies, to name but a few. It would seem, as these trends indicate, that people are done with the artificial and are tired of fakery; they yearn for something with authenticity. Items such as fossils and minerals offer a window into the natural world within one’s own home.
“Some are incredibly rare as well. But I think the main point is that most people are in sheer awe when they look at something that was created millions of years ago and which is still appealing to us”, said Fuller. “To imagine that this fossilised dinosaur or crab used to live on this planet such a long time ago, and is now one of the prized possessions in your collection is quite mind-blowing. Antiques and the amazing craftsmanship used to create them will always attract us, but I think it is the fact that fossils are not man-made that makes us look at them in wonder.”
Crucial to this trend is the fact that fossils and minerals complement almost any type of interior design. They offer contrast to a modern room with soft furnishings, yet not in the garish way that a cumbersome 17th century dining table might. Given the variety of sizes, colours and types available, there is something for everyone and every budget. “Fossils are also still reasonably priced, so are more accessible to the general public and not restricted to those with millions in their bank accounts”, Fuller said.
Their backgrounds make talking points like no other; it’s impossible not to be interested in their age, formation and aesthetic value.
“They are not man-made and, in terms of antiquity, they are much older. And, of course, they almost always have a story”, Fuller said. “People tend to buy antiques because they are interested in their history and they look great in their homes. Fossils and minerals tick all those boxes, but as our homes are getting more contemporary, fossils actually fit in better. They look better in a minimalist home than most antiques, while still being quirky enough to be a real focal point.”
When asked if he sees this trend continuing in the coming years, Fuller’s response was clear: “Absolutely, and especially because it is an area in which young people are becoming particularly interested, for all the above reasons. Summers Place Auctions established specific natural history sales with our first Evolution sale in 2013, but we have since gone from one specialist auction a year to including natural history items in all our sales – four in total. There is always a huge interest, but our last sale, which included the natural history collection of the Emmen Zoo, was the best yet – every single lot sold. We offered items at prices as low as £30, up to over £100,000.”
Cyclical nature
As shown throughout history, the trend for antiques in the home comes in waves. Wider phenomena, it would seem, have a large role to play; something may occur in popular culture that can ignite a craze, and a shift within an economy can spur a new trend. Take the hit show Mad Men; watched by millions and considered by many to be one of the greatest dramas of all time, the programme, which depicted life in a New York advertising agency in the 1960s, had a direct impact on the antique market. As the show’s popularity grew, so did that of sleek mid-century furniture, with sales of pieces by Charles and Ray Eames, and Jean-Michel Frank soaring during the show’s run. However, sales of such items have begun to slow once more since the show ended in 2015, demonstrating the fickle nature of tastes and trends when it comes to interior design, popular culture and what’s ‘in’.
The growing demand for Chinese antiquities offers another important lesson for the antiques world. Given the exponential growth in the Chinese economy over the past three decades, a huge social shift has taken place in the country, with a sizeable middle class now present for the first time in the country’s history. This expansion and growth in disposable income has allowed considerably more people in China to own their own homes and, consequently, to invest in them and in objects of aesthetic value. Interestingly, this shift has taken place at the same time as a significant cultural transition within the country, whereby symbols of the past, which were once neglected and even rejected, have regained their prominence. Until recently, all reminders of the China’s imperial past were overlooked by the ruling regime and, as a result, the public. However, a renewed zeal for Chinese history has seen citizens reach out for objects of cultural significance. This trend has led Chinese buyers to scour the globe in search of rare pieces.
The western trend for fossils and minerals may be in line with contemporary tastes, yet this too is likely to pass at some point – it may take several years, but it will pass. Evidently, the appetite for antiques, and for the various individual categories themselves, comes and goes. They are a reflection of society, the state of the economy, and of what was valued at any one time. At present, we are at a stage where the natural is lovingly embraced, which is clearly reflected in what we eat and how we style our homes. But the future may look very different. Perhaps period decor will come back into fashion, perhaps the dining room will have a revival, and maybe even large brown furniture will have its day once more.
Ultimately, the antiques market has a life of its own. It has its own ebb and flow, and is certainly an interesting reflection of society. Although the antique market is shrinking in general, all is not lost for those invested in it; who knows what we’ll once again value in the future?

Human teeth discovered in southern China provide evidence that our species left the African continent up to 70,000 years earlier than prevailing theories suggest, a study published on Wednesday said.
Homo sapiens reached present-day China 80,000-120,000 years ago, according to the study, which could redraw the migration map for modern humans.
"The model that is generally accepted is that modern humans left Africa only 50,000 years ago," said Maria Martinon-Torres, a researcher at University College London and a co-author of the study.
"In this case, we are saying the H. sapiens is out of Africa much earlier," she told the peer-reviewed journal Nature, which published the study.
While the route they travelled remains unknown, previous research suggests the most likely path out of East Africa to east Asia was across the Arabian Peninsula and the Middle East.
The findings also mean that the first truly modern humans -- thought to have emerged in east Africa some 200,000 years ago -- landed in China well before they went to Europe.
There is no evidence to suggest that H. sapiens entered the European continent earlier than 45,000 years ago, at least 40,000 years after they showed up in present-day China.
The 47 teeth exhumed from a knee-deep layer of grey, sandy clay inside the Fuyan Cave near the town of Daoxian closely resemble the dental gear of "contemporary humans," according to the study.
They could only have come from a population that migrated from Africa, rather than one that evolved from an another species of early man such as the extinct Homo erectus, the authors said.
The scientists also unearthed the remains of some 38 mammals, including specimens of five extinct species, one of them a giant panda larger than those in existence today.
No tools were found.
"Judging by the cave environment, it may not have been a living place for humans," lead author Wu Liu from the Chinese Academy of Science in Beijing told AFP.
The study, published in the journal Nature, also rewrites the timeline of early man in China.
Up to now, the earliest proof of H. sapiens east of the Arabian Peninsula came from the Tianyuan Cave near Beijing, and dated from no more than 40,000 years ago.
The new discovery raises questions about why it took so long for H. sapiens to find their way to nearby Europe.
"Why is it that modern humans -- who were already at the gates -- didn't really get into Europe?", Martinon-Torres asked.
Wu and colleagues propose two explanations.
The first is the intimidating presence of Neanderthal man. While this species of early human eventually died out, they were spread across the European continent up until at least some 50,000 years ago.
"The classic idea is that H. sapiens... took over the Neanderthal empire, but maybe Neanderthals were a kind of ecological barrier, and Europe was too small a place" for both, Martinon-Torres said.
Another impediment might have been the cold.
Up until the Ice Age ended 12,000 years ago, ice sheets stretched across a good part of the European continent, a forbidding environment for a new species emerging from the relative warmth of East Africa.
"H. sapiens originated in or near the tropics, so it makes sense that the species' initial dispersal was eastwards rather than northwards, where winter temperatures rapidly fell below freezing," Robin Dennell of the University of Exeter said in a commentary, also in Nature.
Martinon-Torres laid out some of the questions to be addressed in future research, using both genetics and fossil records.
"What are the origins of these populations, and what was their fate? Did they vanish? Could they be the ancestors of later and current populations that entered Europe?"
She also suggested there might have been "different movements and migrations" out of Africa, not just one.
Besides the prehistoric panda, called Ailuropoda baconi, the scientists found an extinct species of a giant spotted hyaena.
An elephant-like creature called Stegodon orientalis and a giant tapir, also present, were species that may have survived into the era when the Chinese had developed writing, some 3500 years ago.
The cache of teeth nearly went unnoticed, Wu told AFP.
He and his Chinese colleagues discovered the cave -- and its menagerie of long-deceased animals -- in the 1980s, but had no inkling that it also contained human remains.
But 25 years later, while revisiting the site, Wu had a hunch.
"By thinking about the cave environment, we realised that human fossils might be found there," he told AFP by email. "So we started a five-year excavation."

The world's largest canyon may lie under the Antarctic ice sheet, according to analysis of satellite data by a team of scientists, led by Durham University.
Although the discovery needs to be confirmed by direct measurements, the previously unknown canyon system is thought to be over 1,000km long and in places as much as 1km deep, comparable in depth to the Grand Canyon in USA, but many times longer.
The canyon system is made up of a chain of winding and linear features buried under several kilometres of ice in one of the last unexplored regions of the Earth's land surface: Princess Elizabeth Land (PEL) in East Antarctica. Very few measurements of the ice thickness have been carried out in this particular area of the Antarctic, which has led to scientists dubbing it one of Antarctica's two 'Poles of Ignorance'.
The researchers believe that the landscape beneath the ice sheet has probably been carved out by water and is either so ancient that it was there before the ice sheet grew or it was created by water flowing and eroding beneath the ice.
Although not visible to the naked eye, the subglacial landscape can be identified in the surface of the ice sheet.
Faint traces of the canyons were observed using satellite imagery and small sections of the canyons were then found using radio-echo sounding data, whereby radio waves are sent through the ice to map the shape of the rock beneath it. These are very large features which appear to reach from the interior of Princess Elizabeth Land to the coast around the Vestfold Hills and the West Ice Shelf.
The canyons may be connected to a previously undiscovered subglacial lake as the ice surface above the lake shares characteristics with those of large subglacial lakes previously identified. The data suggests the area of the lake could cover up to 1250km², more than 80 times as big as Lake Windermere in the English Lake District.
An airborne survey taking targeted radio-echo sounding measurements over the whole buried landscape is now underway with the aim of unambiguously confirming the existence and size of the canyon and lake system, with results due later in 2016.
Lead researcher, Dr Stewart Jamieson, from the Department of Geography at Durham University in the UK, said: "Our analysis provides the first evidence that a huge canyon and a possible lake are present beneath the ice in Princess Elizabeth Land. It's astonishing to think that such large features could have avoided detection for so long.
"This is a region of the Earth that is bigger than the UK and yet we still know little about what lies beneath the ice. In fact, the bed of Antarctica is less well known than the surface of Mars. If we can gain better knowledge of the buried landscape we will be better equipped to understand how the ice sheet responds to changes in climate."
Co-Author Dr Neil Ross from Newcastle University in the UK, said: "Antarctic scientists have long recognised that because the way ice flows, the landscape beneath the ice sheet was subtly reflected in the topography of the ice sheet surface. Despite this, these vast deep canyons and potential large lake had been overlooked entirely.
"Our identification of this landscape has only been possible through the recent acquisition, compilation and open availability of satellite data by many different organisations (e.g. NASA, ESA and the US National Snow and Ice Data Center), to whom we are very grateful, and because of some serendipitous reconnaissance radio-echo sounding data acquired over the canyons by the ICECAP project during past Antarctic field seasons."
Co-Author Professor Martin Siegert, from the Grantham Institute at Imperial College London, UK, said: "Discovering a gigantic new chasm that dwarfs the Grand Canyon is a tantalising prospect. Geoscientists on Antarctica are carrying out experiments to confirm what we think we are seeing from the initial data, and we hope to announce our findings at a meeting of the ICECAP2 collaboration, at Imperial, later in 2016.
"Our international collaboration of US, UK, Indian, Australian and Chinese scientists are pushing back the frontiers of discovery on Antarctica like nowhere else on earth. But the stability of this understudied continent is threatened by global warming, so all the countries of the world now must rapidly reduce their greenhouse gas emissions and limit the damaging effects of climate change."

The Museo Civico Archeologico is hosting Egypt. Millennia of Splendour. Beneath the two towers, the splendour of a civilisation that lasted thousands of years and has always fascinated the entire world, has sprung back to life: the Egypt of the pyramids, pharaohs and multiform gods, but also that of sensational discoveries, captivating archaeology, passionate collecting and rigorous scholarship.
The exhibition ‘Egypt’, which is being held at the Museo Civico Archeologico in Bologna, is not just an exposition of high visual and scientific impact, but also an unprecedented international enterprise: the Egyptian collection of the National Museum of Antiquities in Leiden, Netherlands – among the top ten in the world – and that of the Bologna museum – among the most important in Italy for the quantity, quality and state of conservation of its collections – have been brought together in an exhibition space measuring around 1,700 metres, filled with art and history.
500 finds, dating from the Pre-Dynastic Period to the Roman Period, gave been brought from the Netherlands to the Bologna museum. And, together with the masterpieces from Leiden and Bologna, the exhibition also includes important loans from the Museo Egizio in Turin and the Museo Egizio in Florence, creating a network of the most important Italian museums.
For the first time, the masterpieces of the two collections are being displayed side by side, including the Stele of Aku (Twelfth–Thirteenth Dynasty, 1976–1648 BC), the ‘major domo of the divine offering’, with a prayer describing the otherworldly existence of the deceased in a tripartite world divided into sky, earth and the beyond; gold items attributed to General Djehuty, who led the Egyptian troops to victory in the Near East for the great conqueror Pharaoh Thutmose III (1479–1425 BC); the statues of Maya, superintendent of the royal treasury of Tutankhamen, and Merit, a chantress of the god Amun, (Eighteenth Dynasty, reigns of Tutankhamen and Horemheb, 1333–1292 BC), the most important masterpieces in the National Museum of Antiquities in Leiden have left the Netherlands for the first time for the Bologna exhibition; and, among the numerous objects attesting to the refined lifestyle of the most wealthy Egyptians, a Mirror Handle (1292 BC) in the shape of a young woman holding a small bird in her hand.
Lastly, for the first time 200 years after the discovery of his tomb in Saqqara, the exhibition offers the unique and once-in-a-lifetime opportunity to see the important Reliefs of Horemheb reunited: Horemheb was the head commander of the Egyptian army during the reign of Tutankhamen, then rising to become the final sovereign of the Eighteenth Dynasty, from 1319 to 1292 BC and the reliefs are divided between the collections in Leiden, Bologna and Florence.
Thousands of years of the history of a unique civilisation revealed in a major exhibition that brings together masterpieces from important world collections and tells of the pyramids and pharaohs, the great captains and priests, the gods and other divinities, and the people that made Egyptian history and that, thanks to discoveries, archaeology and collecting, never stop enchanting, revealing, intriguing, fascinating and charming generation after generation.
The Seven Exhibition Sections
The Pre-Dynastic and Archaic Periods – At the Origins of History: The transition from raw material to form, from the oral tradition to the written one and from prehistory to history was a fundamental moment for Egyptian civilisation. The Leiden collection is rich in materials documenting the central role played by nature during this long cultural and artistic evolution.
The exhibition opens with a selection of these objects, which are strikingly modern in style, including a vase from the Naqada IID Period (named for a site in Upper Egypt and datable between 3375 and 3325 BC) decorated with ostriches, hills and water motifs. The scene depicted on this vase takes us back to an Egypt characterised by a flourishing landscape later changed over time by climatic changes. Ostriches, here painted red, along with elephants, crocodiles, rhinoceros and other wild animals were common in the Nile region at the time.
The Old Kingdom – A Political/Religious Model Destined for Success and its Weaknesses: The historic period of the Old Kingdom (from the Third to the Sixth Dynasty, roughly between 2700 and 2192 BC) is known for the pyramids and for the consolidation of a bureaucracy at the apex of which stood an absolute sovereign, considered a god on earth and lord of all of Egypt.
This definition of State and its worldly and otherworldly rules, which were highly elitist, are well documented by funerary objects, of which the Leiden museum has a particularly rich collection, including a calcite (alabaster) table for offerings.
Offerings to the deceased were a fundamental part of the funerary ritual, ensuring life after death. The uniqueness of this table, which belonged to a high state official named Defdj, lies in its circular shape, which was unusual, as well as the repetition of the concept of the offering as indicated by the inscription, the sculpted receptacles and, most importantly, the central depiction corresponding to the hieroglyph hotep (offering), or a table upon which one places a loaf of bread.
The Middle Kingdom – The God Osiris and a New Perspective on Life in the Afterworld: The end of the Old Kingdom and the period of political breakdown that followed it led to major changes in Egyptian society, within which the individual had greater responsibility for his own destiny, including in the afterworld. Any Egyptian with the means to build a tomb complete with a sufficient funerary assemblage could now aspire to eternal life. The god Osiris, lord of the afterworld, became Egypt’s most popular divinity.
Many steles now in Leiden and Bologna came from his temple in Abydos, one of Egypt’s most important cult centres. Among them is that of Aku, major domo of the divine offering, who dedicated the stele to Min-Hor-nekht, the form of the ithyphallic god Min worshipped in the city of Abydos. Aku’s prayer to the god describes an otherworldly existence in a tripartite world: the sky, where the deceased were transfigured into stars, the earth, where the tomb was the fundamental point of passage from life to death, and the beyond, where Osiris granted the deceased eternal life.
From the Middle to the New Kingdom – Territorial Control at Home and Abroad: The defeat of the Hyksos, ‘princes from foreign lands’ who invaded and governed northern Egypt for a few generations, marked the beginning of the New Kingdom. An extremely aggressive foreign policy enriched Egypt, and this was one of its periods of greatest splendour. The social class of professional warriors rose to the top of the state hierarchy and spawned a number of ruling dynasties.
The wealth and prestige of these soldiers was also expressed in the production of sophisticated objects, including the gold items attributed to Djehuty, a general under the pharaoh Thutmose III. The Egyptian goldsmith’s art has survived in works of high artistic and economic value, an example being the pectoral element on view in the exhibition.
This piece is a sophisticated exemplar attributed to the tomb of General Djehuty, the man to whom the sovereign Thutmose III entrusted control of his foreign territories. Representing a blue lotus flower, a symbol of rebirth and regeneration, it must have served as the central element of an elaborate pectoral. The scroll engraved on the back suggests that the piece was given personally by Thutmose III.
The Saqqara Necropolis of the New Kingdom: The Leiden and Bologna museums can be considered ‘twins’ in a certain sense, since they house two important groups of antiquities from Saqqara, one of the necropolises of the city of Memphis. During the New Kingdom, this early Egyptian capital returned to its role as a strategic centre for the expansionist policy of the sovereigns of the Eighteenth Dynasty.
This is seen in the funerary monuments of high state officials who held administrative, religious and military roles, including the tombs of the superintendent of Tutankhamen’s royal treasury, Maya, and his wife, Merit, chantress of Amun, and that of Horemheb, head commander of Tutankhamen’s army and the pharaoh’s crown prince.
The statues of Maya and Merit arrived in the Netherlands in 1829 as part of the collection of Giovanni d’Anastasi. More than a century and a half would pass before, in 1986, a British/Dutch archaeological expedition identified the tomb from which they came, southeast of the pyramid of Djoser at Saqqara. These statues, which are the greatest masterpieces in the collection of the National Museum of Antiquities in Leiden, left the Dutch museum for the first time to be displayed in the exhibition.
It should be noted that, when the Egypt Exploration Society of London and the National Museum of Antiquities in Leiden began excavation work southeast of the Djoser pyramid in 1975, the goal was to find the tomb of Maya and Merit. It was therefore a great surprise when they instead discovered the burial of General Horemheb, who had capped off his stunning career by becoming the last sovereign of the Eighteenth Dynasty.
His tomb, which has a temple structure, is characterised by a pylon entrance, three large courts and three cult chapels facing onto the innermost court, which has a peristyle structure. This court is where most of the reliefs preserved in Leiden and Bologna were found, narrating Horemheb’s most important military feats against the populations bordering Egypt: the Asians, Libyans and Nubians.
The New Kingdom – Prosperity after the Conquest: Refined furnishings, musical instruments, table games and jewellery: these are just a few of the luxury goods attesting to the widespread prosperity enjoyed in Egypt as a result of the expansionist policy of the sovereigns of the New Kingdom. Through these sophisticated objects, it is possible to conjure up moments of everyday life, imagining what it was like living inside a royal palace or the residence of a high official. One example in the exhibition is a mirror handle in the graceful, sensual shape of a young women holding a small bird in her hand.
Egypt in the First Millennium: In the first millennium BC, Egypt was characterised by the increasingly clear weakness of its central power to the advantage of local governors who gave themselves the role of ruling dynasts. The loss of political and territorial power weakened Egypt’s defence capacity at its borders, opening the way for Nubian, Assyrian and Persian invasions. The temples remained strong centres of power, and managed a sizeable portion of the economy and the transmission of knowledge, taking on the role of a political intermediary between the ruling power and the devout populace.
Many of the masterpieces on view in the exhibition were part of the funerary assemblages of priests and came from important temple areas. Among them is the sarcophagus of Peftjauneith, which represents the likeness of the god Osiris, wrapped in a linen shroud and with a green face evoking the concept of rebirth. The refined decoration of this sarcophagus confirms the high rank of its owner (the superintendent of the possessions of a temple in Lower Egypt) in the temple sphere. Of particular note is the interior scene of the sky goddess Nut swallowing the sun every evening (to the west) to then give birth to it in the morning (to the east).
Alexander the Great’s conquest of Egypt in 332 BC ended the ‘pharaonic’ phase of Egyptian history. The period of Greek domination was begun by his successors, the Ptolemies, the last of whom was the renowned Cleopatra VII.
The golden decline of Egypt would continue for many more centuries, beyond the Roman conquest in 31 BC up to Arab domination in the sixth century AD.
The dialogue between old and new, local and foreign that distinguished the Greco-Roman period brought a return to high artistic achievements, including the celebrated Fayum portraits, exquisite examples of which from the Leiden collection are on view in the exhibition

An ancient basin hidden beneath the Greenland ice sheet, discovered by researchers at the University of Bristol, may help explain the location, size and velocity of Jakobshavn Isbræ, Greenland's fastest flowing outlet glacier.
The research also provides an insight into what past river drainage looked like in Greenland, and what it could look like in the future as the ice sheet retreats.
Michael Cooper and colleagues from Bristol's School of Geographical Sciences and Cabot Institute, and Imperial College London, studied the bedrock in Greenland using data collected mainly by NASA (through Operation Ice Bridge), as well as various researchers from the UK and Germany, over several decades. This data is collected by aircraft using ice penetrating radar, which bounces back off the bedrock underneath the ice (as ice is mostly transparent to radio waves at certain frequencies).
Mr Cooper said: "The drainage basin we discovered shows signs of being carved by ancient rivers, prior to the extensive glaciation of Greenland (i.e. before the Greenland Ice Sheet existed), rather than being carved by the movement of ice itself. It has been remarkably well preserved – and has not been eroded away by successive glaciations. The channel network has never been seen before by humans – it was last uncovered around 3.8 million years ago."
The size of the drainage basin the team discovered is very large, at around 450,000 km2, and accounts for about 20 per cent of the total land area of Greenland (including islands).
This is comparable to the size of the Ohio River drainage basin, which is the largest tributary of the Mississippi. The channels the team mapped could more appropriately be called 'canyons', with relative depths of around 1,400 metres in places, and nearly 12km wide, all hidden underneath the ice.
As well as being an interesting discovery of great size, the channel network and basin was instrumental in influencing the flow of ice from the deep interior to the margin, both now and over several glacial cycles, as well as influencing the location and speed of the Jakobshavn ice stream.
The study is published in >Geophysical Research Letters.

Archaeologists have uncovered a stone grinding tool in southern Italy which shows signs it was used to make flour that was boiled into gruel or baked into bread.
The discovery, which predates the dawn of farming, suggests that stone age man's first cultivated meal may have been a bowl of porridge made from grains growing wild and is the earliest known instance of human consumption of oats.
The find was made by a team led by Marta Mariotti Lippi at the University of Florence in Italy who made analysed starch grains found on the artefact.
They found evidence that the stone's creators also heated the grains before grinding them, perhaps to dry them out in the colder climate of the time and make the grain easier to grind and longer-lasting.
This multi-stage process would have been time consuming, but beneficial, while turning it into flour would have been a good way to transport it, which was important for Palaeolithic nomads.
Evidence of porridge consumption in Scotland dates back to 4,000 BC, when oats and other grains began to be cultivated by the first farmers.
Mariotti Lippi’s team hopes to continue studying ancient grinding stones to find out more about the stone age plant diet.
The stone was found in the Grotta Paglicci, Apulia, which was home to stone age hunter gatherers between 34,000 and 32,000 years ago and contains mural paintings, depicting horses and handprints. Images of goats, cows, a serpent, a nest with eggs, and a hunting scene have also been found engraved on bone.
Archaeologist Matt Pope, of University College London, said that the find shed light on the diet of early humans and the spread of food cultivation.
He said: “There is a relationship there to be explored between diet, experimentation with processing plant food and cultural sophistication.
“We’ve had evidence of the processing of roots and cattails, but here we’ve got a grain, and a grain that we’re very familiar with.
“If we were to look more systematically for ground stone technology we would find this is a more widespread phenomenon.”
The study is published in Proceedings of the National Academy of Sciences.

To the 2012 Summer Olympic Games in London have constructed the portable basketball arena.
The 2012 Olympic Games which will take place in London, will be rather burdensome for the British budget. For example, for the Olympic Stadium are invested more 500,000,000 pounds. Besides it, in plans the tens of Olympic objects, sport arenas, and infrastructural complexes. Among the Great Olympic objects is possible to name the Center of Water-sports (by Zaha Hadid), and the 1st Cable Car in London.
The project of the Basketball Arena which can accept simultaneously twelve thousand spectators, will be developed by the architectural and engineering companies: Sinclair Knight Merz, Wilkinson Eyre and KSS. The main feature of this arena consists that arena will be created from easily erected elements that has allowed to erect all complex for 15 months.
Thus, after the termination of the Olympic and Paraolympic Games this basketball stadium will be quickly disassembled. But not for ever. Further, the basketball arena can be collected again in any place.
Such portable arena will allow to save ten millions pounds. And, if it will be possible to sell this stadium it's even better.
The Department of Antiquities, Ministry of Transport, Communications and Works, announced that an ancient clay figurine has been repatriated to Cyprus from the United Kingdom. The clay figurine depicts a horse and rider/warrior and dates to the Cypro-Archaic period (approximately 700 BC).
The figurine was identified by the Department of Antiquities on the website of a London-based antiquities dealer’s shop. Following a request by the Department of Antiquities and the Cyprus Police, the shop handed over the figurine to the London Metropolitan Police, which in turn, returned it to the Department of Antiquities in July 2016.
The figurine was part of Mr Christakis Hadjiprodromou’s registered private collection that was kept in his house in Ammochostos (Famagusta) prior to the Turkish invasion in 1974. As a result of the invasion, Mr Hadjiprodromou’s residence was pillaged and his collection was looted, with its objects being scattered around the world.

The arrival of intense cold similar to the one raged during the “Little Ice Age”, which froze the world during the XVII century and in the beginning of the XVIII century, is expected in the years 2030–2040.
These conclusions were presented by Prof. V. Zharkova (Northumbria University) during the National Astronomy Meeting in Llandudno in Wales by the international group of scientists, which also includes Dr Helen Popova of the Skobeltsyn Institute of Nuclear Physics and of the Faculty of Physics of the Lomonosov Moscow State University, professor Simon Shepherd of Bradford University (UK) and Dr Sergei Zharkov of Hull University (UK).
It is known, that the Sun has its own magnetic field, the amplitude and spatial configuration of which vary with time. The formation and decay of strong magnetic fields in the solar atmosphere results in the changes of electromagnetic radiation from the Sun, of the intensity of plasma flows coming from the Sun, and the number of sunspots on the Sun’s surface. The study of changes in the number of sunspots on the Sun’s surface has a cyclic structure vary in every 11 years that is also imposed on the Earth environment as the analysis of carbon-14, beryllium-10 and other isotopes in glaciers and in the trees showed.
There are several cycles with different periods and properties, while the 11-year cycle, the 90-year cycle are the best known of them. The 11-year cycle appears as a cyclical reduction in stains on the surface of the Sun every 11 years. Its 90-year variation is associated with periodic reduction in the number of spots in the 11-year cycle in the 50-25%. In 17th century though there was a prolonged of the solar activity called the Maunder minimum, which lasted roughly from 1645 to 1700. During this period, there were only about 50 sunspots instead of the usual 40-50 thousand sunspots. Analysis of solar radiation showed that its maxima and minima almost coincide with the maxima and minima in the number of spots.
In the current study published in 3 peer-reviewed papers the researchers analyzed a total background magnetic field from full disk magnetograms for three cycles of solar activity (21-23) by applying the so-called “principal component analysis”, which allows to reduce the data dimensionality and noise and to identify waves with the largest contribution to the observational data. This method can be compared with the decomposition of white light on the rainbow prism detecting the waves of different frequencies. As a result, the researchers developed a new method of analysis, which helped to uncover, that the magnetic waves in the Sun are generated in pairs, with the main pair covering 40% of variance of the data (Zharkova et al, 2012, MNRAS). The principal component pair is responsible for the variations of a dipole field of the Sun, which is changing its polarity from pole to pole during 11 year solar activity.
The magnetic waves travel from the opposite hemisphere to the Northern hemisphere (odd cycles) or to Southern hemisphere (even cycles), with the phase shift between the waves increasing with a cycle number. The waves interacts with each other in the hemisphere where they have maximum (Northern for odd cycles and Southern for even ones). These two components are assumed to originate in two different layers in the solar interior (inner and outer) with close, but not equal, frequencies and a variable phase shift (Popova et al, 2013, AnnGeo).
The scientists managed to derive the analytical formula, describing the evolution of these two waves and calculated the summary curve which was linked to the variations of sunspot numbers, the original proxy of solar activity, if one used the modulus of the summary curve (Shepherd et al, 2014, ApJ). By using this formula the scientists made first the prediction of magnetic activity in the cycle 24, which gave 97% accuracy in comparison with the principal components derived from the observations.
Inspired by this success, the authors extended the prediction of these two magnetic waves to the next two cycle 25 and 26 and discovered that the waves become fully separated into the opposite hemispheres in cycle 26 and thus have little chance of interacting and producing sunspot numbers. This will lead to a sharp decline in solar activity in years 2030 – 2040 comparable with the conditions existed previously during the Maunder minimum in the XVII century when there were only about 50-70 sunspots observed instead of the usual 40-50 thousand expected.
The new reduction of the solar activity will lead to reduction of the solar irradiance by 3W/m^2 according to Lean (1997). This resulted in significant cooling of Earth and very severe winters and cold summers. “Several studies have shown that the Maunder Minimum coincided with the coldest phase of global cooling, which was called “the Little Ice Age”. During this period there were very cold winters in Europe and North America. In the days of the Maunder minimum the water in the river Thames and the Danube River froze, the Moscow River was covered by ice every six months, snow lay on some plains year round and Greenland was covered by glaciers” – says Dr Helen Popova, who developed a unique physical-mathematical model of the evolution of the magnetic activity of the sun and used it to gain the patterns of occurrence of global minima of solar activity and gave them a physical interpretation.
If the similar reduction will be observed during the upcoming Maunder minimum this can lead to the similar cooling of the Earth atmosphere. According to Dr Helen Popova, if the existing theories about the impact of solar activity on the climate are true, then this minimum will lead to a significant cooling, similar to the one occurred during the Maunder minimum.
However, only the time will show soon enough (within the next 5-15 years) if this will happen.
“Given that our future minimum will last for at least three solar cycles, which is about 30 years, it is possible, that the lowering of the temperature will not be as deep as during the Maunder minimum. But we will have to examine it in detail. We keep in touch with climatologists from different countries. We plan to work in this direction”, — Dr Helen Popova said.
The notion that solar activity affects the climate, appeared long ago. It is known, for example, that a change in the total quantity of the electromagnetic radiation by only 1% can result in a noticeable change in the temperature distribution and air flow all over the Earth. Ultraviolet rays cause photochemical effect, which leads to the formation of ozone at the altitude of 30-40 km. The flow of ultraviolet rays increases sharply during chromospheric flares in the Sun. Ozone, which absorbs the sun’s rays well enough, is being heated and it affects the air currents in the lower layers of the atmosphere and, consequently, the weather. Powerful emission of corpuscles, which can reach the Earth’s surface, arise periodically during the high solar activity. They can move in complex trajectories, causing aurorae, geomagnetic storms and disturbances of radio communication.
By increasing the flow of particles in the lower atmospheric layers air flows of meridional direction enhance: warm currents from the south with even greater energy rush in the high latitudes and cold currents, carrying arctic air, penetrate deeper into the south. In addition, the solar activity affects the intensity of fluxes of galactic cosmic rays. The minimum activity streams become more intense, which also affects the chemical processes in the Earth’s atmosphere
The study of deuterium in the Antarctic showed that there were five global warmings and four Ice Ages for the past 400 thousand years. The increase in the volcanic activity comes after the Ice Age and it leads to the greenhouse gas emissions. The magnetic field of the Sun grows, what means that the flux of cosmic rays decreases, increasing the number of clouds and leading to the warming again. Next comes the reverse process, where the magnetic field of the Sun decreases, the intensity of cosmic ray rises, reducing the clouds and making the atmosphere cool again. This process comes with some delay.
Dr Helen Popova responds cautiously, while speaking about the human influence on climate.
“There is no strong evidence, that global warming is caused by human activity. The study of deuterium in the Antarctic showed that there were five global warmings and four Ice Ages for the past 400 thousand years. People first appeared on the Earth about 60 thousand years ago. However, even if human activities influence the climate, we can say, that the Sun with the new minimum gives humanity more time or a second chance to reduce their industrial emissions and to prepare, when the Sun will return to normal activity”, — Dr Helen Popova summarized.
