ScienceAlert... More than 450 huge earthworks have been discovered in western Brazil, revealing the last vestiges of land use by ancient societies, before the dense foliage of the Amazon rainforest concealed them centuries ago. While nobody knows exactly what these mysterious sites were used for, the landmarks are evidence that indigenous societies habitually cleared and altered the Amazon landscape for hundreds of years before the arrival of Europeans in the Americas. "The fact that these sites lay hidden for centuries beneath mature rainforest really challenges the idea that Amazonian forests are 'pristine ecosystems'," says archaeologist Jennifer Watling from the ...
Physicists make the case that our brains' learning is controlled by entropy

ScienceAlert... The way our brains learn new information has puzzled scientists for decades - we come across so much new information daily, how do our brains store what's important, and forget the rest more efficiently than any computer we've built? It turns out that this could be controlled by the same laws that govern the formation of the stars and the evolution of the Universe, because a team of physicists has shown that, at the neuronal level, the learning process could ultimately be limited by the laws of thermodynamics. "The greatest significance of our work is that we bring the second law of thermodynamics to the analysis of neural networks," lead researcher ...

here are 30 things to start the discussion off. 1. RAF Tornado fighter jet parts Early this year, BAE Systems said that British fighter jets had flown with the first time with components made using 3D printing technology. Its engineers are making parts for four squadrons of Tornado GR4 aircraft, with the aim of saving £1.2m of maintenance and service costs over the next four years. "You are suddenly not fixed in terms of where you have to manufacture these things," said BAE's Mike Murray. "You can manufacture the products at whatever base you want, providing you can get a machine there." 2. Arms for children Time's article from earlier this month on the ...
Scientists have found a crazy new way to print on paper using light

ScienceAlert.. A new method for printing on paper using light promises to be much cheaper, and easier on the environment than the traditional ink-based printing we're used to. Scientists have developed a special nanoparticle coating that's easy to apply to normal paper and changes colour when ultraviolet (UV) light shines on it. The colour change can be reversed when the coating is heated to 120 degrees Celsius (248 degrees Fahrenheit), and allows for up to 80 rewrites. The team of researchers from the US and China say that their new high-resolution light printing technique could be used everywhere from newspapers to labels, saving on the cost of ink and paper, and on the ...

Hundreds of ancient earthworks resembling those at Stonehenge were built in the Amazon rainforest, scientists have discovered after flying drones over the area. The findings prove for the first time that prehistoric settlers in Brazil cleared large wooded areas to create huge enclosures meaning that the 'pristine' rainforest celebrated by ecologists is actually relatively new. The ditched enclosures, in Acre state in the western Brazilian Amazon, have been concealed for centuries by trees, but modern deforestation has allowed 450 to emerge from the undergrowth. They were discovered after scientists from the UK and Brazil flew drones over last year. The earthworks, known by ...

They always say look before you leap, but what about before you go to the bathroom? Homeowners, you might want to put snake inspections at the top of your yearly maintenance checklist. You thought “Snakes on a Plane” was bad? (It was.) Wait until you encounter snakes in the drain or, worse, the commode. Last week, a family in Jones County in West Texas spotted a deadly rattlesnake emerging from one of their home’s toilets, according to the Dallas News. The father, Jason McFadden, called Big Country Snake Removal located in nearby Buffalo Gap, TX. The Washington Post reported that by the time the inspector, Nathan Hawkins, arrived on the scene, the toilet snake had already ...
Scientists have a plan to replace fossil fuels with nuclear fusion by 2030
Post Date: 2017-02-03 03:10:35 by Tatarewicz
0 Comments
ScienceAlert... Nuclear fusion is premised on building technology that would replicate the reaction that naturally powers our Sun - two light atoms, in this case, hydrogen, are fused together under extreme temperatures to produce another element, helium. The process would release vast amounts of clean energy drawn from an almost limitless fuel source, with nearly zero carbon emissions. However, it has yet to be done on a scale that would make it usable. Canadian scientists are hoping to change that, announcing plans to harness and develop nuclear fusion technology so they can deliver a working nuclear fusion plant prototype by 2030. What they need, however, is for the government to ...

SYDNEY, Feb. 2 (Xinhua) -- Scientists at the University of Queensland in Australia announced on Thursday they have discovered a new bacterium that could change long thought to be certain theories on evolution. Regular convention dictates there are three domains of life; bacteria and archaea which are single cell organisms without a nucleus, and eukaroytes, which comprise of every other living creature, big and small. A particular bacterium has never fit the mould, 'Gemmata obscuriglobus' has been given the monniker of the platypus of microbiology, due to how it defies convention by having features that are inclusive of those found in eukaroytes. The discovery by the team led by ...

Jan. 31 (UPI) -- Like most islands, Mauritius is made of up of mostly young rock, formed by hardened magma. But as new research confirmed, an ancient "lost continent" is hiding beneath the fresh face of Mauritius. According to an international team of scientists, Mauritius is a continental fragment, severed from Madagascar as the the supercontinent, Gondwana, split into Africa, India, Australia and Antarctica, some 200 million years ago. Scientists realized Mauritius' continental origins while studying bits of the mineral zircon found on the island. "Earth is made up of two parts -- continents, which are old, and oceans, which are 'young'. On the continents ...
Swearing is actually a sign of more intelligence - not less - say scientists

ScienceAlert... The use of obscene or taboo language - or swearing, as it’s more commonly known - is often seen as a sign that the speaker lacks vocabulary, cannot express themselves in a less offensive way, or even lacks intelligence. Studies have shown, however, that swearing may in fact display a more, rather than less, intelligent use of language. While swearing can become a habit, we choose to swear in different contexts and for different purposes: for linguistic effect, to convey emotion, for laughs, or perhaps even to be deliberately nasty. Psychologists interested in when and why people swear try to look past the stereotype that swearing is the language of the unintelligent ...

ScienceAlert... Researchers have found a way to turn cheap, everyday cooking oil into the wonder material graphene - a technique that could greatly reduce the cost of making the much-touted nanomaterial. Graphene is a single sheet of carbon atoms with incredible properties - it's 200 times stronger than steel, harder than diamond, and incredibly flexible. Under certain conditions, it can even be turned into a superconductor that carries electricity with zero resistance. That means the material has the potential to make better electronics, more effective solar cells, and could even be used in medicine. Last year, a study suggested that graphene could help mobile phone batteries last ...

WEDNESDAY, Jan. 11, 2017 (HealthDay News) -- A molecule produced in the digestion of red meat, eggs and dairy products is linked to an increased risk of a fatal heart attack or stroke, researchers say. Patients with high blood levels of trimethylamine N-oxide (TMAO) were six times more likely within the next month to die, suffer a heart attack or stroke, or require surgery to reopen a blocked artery, according to the study. TMAO also predicted long-term health risks, researchers said. People with the highest blood levels of TMAO were nearly twice as likely to die within seven years. "A high TMAO level predicted who went on to experience a major cardiovascular event," said ...
Earth’s magnetic poles are set to swap places - and we're totally unprepared

ScienceAlert... Earth’s magnetic field surrounds our planet like an invisible force field - protecting life from harmful solar radiation by deflecting charged particles away. Far from being constant, this field is continuously changing. Indeed, our planet’s history includes at least several hundred global magnetic reversals, where north and south magnetic poles swap places. So when’s the next one happening and how will it affect life on Earth? During a reversal the magnetic field won’t be zero, but will assume a weaker and more complex form. It may fall to 10 percent of the present-day strength and have magnetic poles at the equator or even the simultaneous existence ...
Key to restoring great tomato flavor discovered

ScienceDaily... Modern tomatoes lack sufficient sugars and volatile chemicals critical to better flavor. Those traits have been lost during the past 50 years because breeders have not had the tools to routinely screen for flavor, he said. What's wrong with the supermarket tomato? Consumers say they lack flavor, so a University of Florida researcher led a global team on a mission to identify the important factors that have been lost and put them back into modern tomatoes. In a study published today in the journal Science, Harry Klee, a professor of horticultural sciences with UF's Institute of Food and Agricultural Sciences, identifies the chemical combinations for better tomato ...

Independent. A self-styled alien hunter believes he has spotted a UFO during a live feed from the International Space Station. John Craddick, from Wolverhampton in the UK, claims he has never seen anything like it before. He told the Mirror: "I've been watching it [the live feed] for years but never seen any UFOs on it before. "I was showing a friend how it worked at around 11.30pm when the feed cut out, and 35 seconds after it came back on, this object appeared. "At first it was really small and then it grew bigger, lasting for about 25 seconds," he said. Mr Craddick claims that it must be alien because "nothing human can fly that high" Below shows ...

ScienceAlert..What is the smartest species in the world? You might think it's humans by a long shot, but the reality is a lot more complicated. Frans de Waal, a primatologist at Emory University, has a new book out called Are We Smart Enough to Know How Smart Animals Are? and in it he gives hundreds of examples of surprising intelligence from non-human species, including many instances where other animals appear to be smarter than we are. Chimpanzees, for instance, can easily beat humans at recalling a set of numbers that was displayed for a fraction of a second. Octopuses can learn to open pill bottles protected by childproof caps, which many humans can't figure out on their ...
