Eight colonies of common ants were shipped to the International Space Station last December to study how microgravity might affect the creatures. So, how did the ants fare? Well, surprisingly good actually. The dexterous ants clung to the surface of the station and migrated freely (under supervision of course) despite weightlessness. Of course, their movements weren't as coordinated as on Earth and since they rely on a sort of hive mind to coordinate the colony, researchers believe studying their mishaps in microgravity might aid in building better robots.
More than half a century in question, scientists now confirm that the tiny blackpoll warbler flies nonstop over the North Atlantic Ocean each autumn from New England to South America. The trip takes three days, during which the bird foregoes any rest, sleep or meal. It also absorbs its own intestines.
There's a fine line between being seen as a non-conformist (higher status) and sloppy dresser (lower status). But what sets apart people like Zuckerberg from regular people like you or me (apart from money, of course...)? Well, to get to the root of this silver line, the Harvard researchers studied the observers themselves to understand what are the boundary conditions and signals that make people confer higher status to nonconforming individuals over conforming ones.
Ironically enough, one male researcher from England used tampons to detect grey water contamination, or laundry system run off, that might be present in waterways. The tampons absorbed key signature chemicals that glow in the dark, making them easy to use and cheap. Moreover, it's more reliable than consecrated and expensive methods.
The birds are chirping, the flowers are blooming, and citizen scientists… do citizen science! In case you’re not familiar with the concept, citizen science are activities supported (or sponsored) by universities, organizations, institutes or governments through which everyone can provide meaningful scientific contributions. Activities can vary greatly (from counting birds to analyzing galaxy clusters), and […]
I know, the title sounds like one of those scams that promise you'll lose weight - but this is all science all the way. Researchers in Sri Lanka have found a simple way of cooking the rice that not only reduces calories by half, but also provides other health benefits. The key addition is coconut oil.
Mice that had gut bacteria transferred from other mice fed with a high fat diet changed their behavior in a negative way, exhibiting anxiety or impaired memory. The findings suggest that apart from heart disease and stroke, obesity might put people's mental health at risk as well.
In a most unexpected find, the same University of Manchester team that isolated graphene for the first time in 2003 found that water flattens into square crystals - a never encountered lattice configuration - when squeezed between two layers of graphene. The square ice qualifies as a new crystalline phase of ice, joining 17 others previously discovered. The finding could potentially improve filtration, distillation and desalination processes.
A group of biochemical engineers in the US have managed to give a volunteer complete night vision, allowing him to see for 50 meters in almost complete darkness for several hours. To make things even better, they did this without any injections or lenses - only eye drops.
A team at Stanford and MIT has devised a novel configuration that combines silicon - the leading solar cell semiconductor - and perovskite - a cheap mineral, only recently exploited for converting solar energy - to form two different layers of sunlight-absorbing material in order to harness energy across a wider spectrum. While performance at this stage is not impressive (it's equally as good or bad as conventional single-layer silicon cells), researchers believe they have methods at their disposal that could double efficiency. If that were to happen, than these could be the cheap, but efficient solar cells we've all been waiting for.
Stem cells were coaxed to grow into 3D dimensional mini lungs, or organoids, for the first time. These survived for more than 100 days. These pioneering efforts will serve to deepen our understanding of how lungs grow, as well as prove very useful for testing new drugs' responses to human tissue. Hopefully, once human tissue grown in the lab becomes closer and close to the real deal (cultured hearts, lungs, kidneys etc.), animal testing might become a thing of the past.
Scientists are working to gather more and more details about Icelandic DNA, in an attempt to design better drugs and understand how drugs react to genetic variation. So far, the DNA of over 1% of all Icelanders has been sequenced and more will likely follow. This operation is conducted by Amgen's DeCode Genetics. The team now claims that they can identify every woman at high-risk of breast cancer "at the touch of a button" and it would be "criminal" not to use the information.
For the first time, researchers have discovered a vertebrate able to change the texture of its skin from smooth to spiny. The new frog species was found in Ecuador in the plentiful moss surrounding the native forest.
It almost sounds too cheesy to be true: NASA wants to send a shuttle to an asteroid, pluck a piece of it, then make it return to the Moon and orbit it. Then, brave astronauts will go and retrieve the sample, bringing it back to Earth for study. But that's exactly what astronomers and engineers at the space agency want to do.
Most people tend to think of the Earth in terms of crust, mantle and core, and while those are indeed the largest "layers" (you can't properly call the mantle a layer though), each one of them is made from other, thinner layers. Now, researchers from the University of Utah have identified another one of these thinner layers, 930 miles beneath our feet.
What do fires and deep sounds have in common? Not much right now, but they might have a lot in the future.Two George Mason University students have designed a device that uses sound waves to put out fires, thus potentially eliminating the need for carrying around huge quantities of water and costly cleaning operations. Here's how it works:
Some 30 new bean varieties have been cross-bred by researchers in order to make these more resistant to rising temperatures. Often called the 'meat of the poor', more than 400 million people around the world depend on beans for their daily protein intake. Being particularly vulnerable to temperature means that bean farms, whether large or home subsistence gardens, could be obliterated by climate change this century. The new beans can withstand temperatures three to four degrees Celsius greater than those currently grown by farmers, enough, the researchers say, to keep yield losses to a minimum.
Tesla Motors are out to change the world - and they're doing it fast, and in style. Like many other of their projects, this one seemed to pop up out of nowhere: Tesla have designed a battery that can power your home and even larger utility buildings. In other words - it could take your house out of the grid.
China is the largest polluter in the world at the moment, and they’re also reaping what they sew. But you can’t accuse the Chinese for not trying to right their ways – at least some of them; in an effort to mitigate the ridiculous amounts of smog that clouds some of China’s cities, scientists have […]
When you gotta eat... well you gotta eat, even in space. On March 23, 1965 astronaut John Young launched to Earths' orbit aboard the Gemini 3. With him was crewmate Gus Grissom and a two days old corn beef sandwich, smuggled without permission on the spacecraft.
There's good news, and bad news. The good news is that an extremely rare bunny has been observed for the first time in 20 years, but the bad news is that their numbers seem to have dwindled more than ever, and we may never see them again.
Finland, one of the educational hotspots of the world, is committed to a revolution in education: by 2020, they will move on to a topic type of education. In other words, you won't be learning about math, physics and chemistry, but you'll be learning specific topics - eliminating the "what's the point of learning this?" type of questions.
Boeing, a major aircraft and military manufacturer, just secured a patent that describes a Star Trek-like force shield, meant to protect vehicles operating in war zones. I love it when engineers are inspired by science fiction - it means that the authors really did a great job, not only at foreseeing the future, but also in offering the incentive to bring these sort of contraptions to real life.
A chance discovery has provided experimental evidence that stars may generate sound. While he was examining the interaction of an ultra-intense laser with a plasma target, John Parsley from the University of York found that interfering plasma generates a series of pressure pulses - in other words, sounds.
A group of leading scientists and non-profit organizations are urging museums of science and natural history to break their ties with the Koch brothers, climate-change deniers and industrialists. The two brothers of Koch Industries, the second largest privately-held company in the US, are funding misinformation campaigns regarding global warming and humanity’s impact on the planetary […]
The Stork’s Bill (Erodium circutarium) is a incredible plant which evolved its own seed drilling mechanism. The vitamin K rich seeds have little tails that coil and uncoil with changes in humidity, burying the seed. When there's high humidity, the seeds turn clockwise. When it's dry, they turn counter-clockwise. This makes it particularly brilliant since no matter how wet it is outside, the seeds will still drill in the ground like a screw, thereby increasing the chance of sprouting.
A longitudinal study that spanned 26 years found that kids exposed to their Finish parents cigarette smoke are at risk of developing plaque in their carotid arteries as they grow into young adults. Previously, second-hand smoke exposure at a young age was linked to later breast cancer and a predisposition to nicotine addiction. Psychologically, having parent smokers may influence children to become smokers themselves when they grow up, triggering a cascade of other health risks.
Paleontologists have found the remains of a "super salamander" - a previously unknown car-sized species of early amphibian. The predatory salamander likely feasted on fish and even small dinosaurs.
For its annual report, the The Alzheimer’s Association in the US claims that more than half of all reported early Alzheimer's diagnoses aren't disclosed to the patient by doctors. This is a situation reminiscent of the 1960s and 1970s when cancer diagnoses were rarely disclosed to patients as the disease was generally seen as incurable. Like in the case of the long-gone cancer stigma, doctors may be doing more harm than good. They don't want patients to lose hope, but being kept in the dark as to their suffering can be equally bad, if not worse.
A park ranger in south China was surprised to find a giant salamander while he was out picking winkles. The giant amphibian measures 83 cm in length (2.5 feet) and weighs 5.5 kg (12 pounds). This amazing creature has remained relatively unchanged since the Jurassic and is widely regarded as a living fossil, but at the […]
A new shocking theory suggests that Jupiter may have sweeped through our solar system much like a wrecking ball, knocking planets out of the solar system our moving them outwards, to the position we see them in today. If this is true, then it might explain why our solar system is a rarity and why life emerged the way it did.
A shocking image went viral a few days ago, with an 11th-century French abbey completely surrounded by water following a super tide. Naturally, many similar photos followed, and many "explanations" emerged, most vaguely referencing the solar eclipse, something about gravitational cycles, and some even stated it was caused by the "tide of the century", although the "tide of the century" comes by every 18 years. So let's take a look at what actually happened.
Even if it was first discovered more than 90 years ago, insulin is still out of reach for a shocking 29 million diabetes patients in the United States. Yes, this is the 21st century, but even so a staggering number of human beings are forced to live in life threatening conditions. But why is insulin so prohibitively expensive? According to Jeremy Greene, M.D., Ph.D., and Kevin Riggs, M.D., M.P.H., it's all because of a series of perverse updates to insulin treatments. While insulin made today is more effective in some instances, previous versions weren't that bad. In fact, they saved lives. Yet, these were replaced with very expensive versions, while the older, much cheaper versions are nowhere to be found on the market anymore. The two authors explore all that's wrong with today's insulin big pharma.
Australian researchers have uncovered what might be the biggest impact asteroid impact zone in the world – at over 400 kilometers (250 miles)! Naturally, the crater isn’t visible today, but geophysicists have found the impact’s scars deep below the surface. Lead researcher Dr Andrew Glikson from the ANU School of Archaeology and Anthropology explains: “The two asteroids […]
Cloning the woolly mammoth is a life long dream for many geneticists and biologists, but the challenges are numerous. Now, we've come a step closer after researchers replaced snips of elephant DNA with those from the woolly mammoth. The changes they've made so far are stable, and even though there's still much work ahead, little by little scientists are building the mammoth's genome one piece at a time. Next stop: actually cloning the mammoth, effectively resurrecting the species back from the dead.
In December 1994, three explorers made a surprising discovery in southern France - a rumble of stones blocking the entrance to a spectacular cave, over 400 meters long and covered with archaeological and palaeontological remains, including the skulls and bones of cave bears, which hibernated there, along with the skulls of an ibex and two wolves. But it was the human traces that were most interesting...
Paris authorities have put in place 24-hour emergency measures to limit the number of cars in traffic as part of their efforts to fight the smog shrouding the city. Today (Monday, March 23) all cars with number plates that end with an even number will be banned from circulating in the Paris region, unless they're carrying 3 or more passengers. Clean cars will also be allowed.
At a recent meeting of the of the American Chemical Society, researchers proposed a novel source of valuable metals: waste water. They proposed a method that could be used to extract valuable metals like gold, silver or titanium which end up in waste water plants via the city's sewage.
Biologists at Tufts Universityand University of Minnesota showed for the first time that bioelectricity signaling between cells guides embryonic brain development in tadpoles. When bioelectricity signaling was hampered, the frog embryos developed abnormal brains. By using drugs that target specific ion channels, the researchers could restore normal patterns to ensure healthy brain growth. This means that careful manipulation of electricity inside the tissue can repair abnormalities caused by genetic defects. It can also be used to grow all sorts of wacky stuff.
Even as a geologist, I can’t help myself from looking at lava with an almost childish fascination — it’s something from the depths of the Earth (literally), with the potential to destroy anything in its path, and also to create new landscapes, drastically changing the surface of the Earth. In the short film above, Lance Page managed […]
Everything is made of stardust - but some things are made of more stardust than others. A new study has found that a single supernova is capable of producing large enough quantities of dust to create thousands of planets like Earth.
Spring officially began in the northern hemisphere Friday on 22:45 GMT, around 30 seconds later than last year. As it so happens, every year spring gets shorter by 30 seconds to a minute, losing the time to summer which gets longer by the same amount. Whose to blame for the later bloom? Why, that wretched tilted axis of course.
While in South American during his 1830 expedition with the HMS Beagle, Charles Darwin came across the fossils of two peculiar hoofed species which he was unable to classify properly. One was Macrauchenia, which looked like a camel with the head of an ant eater, and the other was Toxodon which had the body of rhino, the head of a hippo and the teeth of a rodent. So, was the Macrauchenia related to the camel or the ant eater? Who was Toxodon's closet cousin, the hippo or the rhino? Darwin was puzzled and to no avail concluded these were “perhaps one of the strangest animals ever discovered”. But Darwin didn't have the tools we have today. Now, using a ground breaking technique researchers have sequenced the collagen of a myriad of South American mammals, including Darwin's 'strangest animals' and finally found their real taxonomy.
Barton Bibler, a long time employee of Florida's environmental protection department, was forced by his boss to take a leave of absence after mentioning 'climate change' in a public hearing. He was told not to come back at the office until he had sought mental health examination. This was in response to a violation of an unwritten policy that came into effect after Governor Rick Scott came to office, a notorious climate change denier and controversial figure, which bans employees from using 'climate change', 'global warming', 'rising sea level' and such from public communication. If you find this hilarious, you can stop laughing now. This not the Onion. This is Scott's Florida - the land of ignorance and denial, or so he would like us to believe.
Long before T-rex claimed the top dog spot among terrestrial predators, a vicious crocodile ancestor that walked on its hind legs was at the top of the food chain during the Triassic. The fossils of the Carnufex carolinensis, also known as the the “Carolina Butcher,” were discovered decades ago in the Pekin Formation, a geological formation in North Carolina's Chatham County. It was only recently that researchers reanalyzed the fossils and concluded they were dealing with an all new predator that roamed the Earth several million years before dinosaurs were even around.
With spring starting to settle in, snow is likely the last thing on people's minds - but NASA is taking snow really seriously. They want to put satellites in orbit to understand how the frozen lands in the polar areas are developing and adapting to climate change.
This is it - the pinnacle of technological development, the result of countless research hours; yes, it's a tree.
Fahrenheit may be the best way to measure temperature after all. Why? Because most of us only care about air temperature, not water temperature.
Scientists, in the lab at least, see marijuana differently from growers or users. Like other plants, once you dive into the microworld cannabis looks immensely different from the buds you see online. These amazing pictures which size up the planet’s crystals, trichomes or leafs were taken by Ford McCann and compiled in a book called Cannabis […]
Each year worldwide about one million people decide to take their own lives. Overriding your conservation instincts isn't easy, let's say, and this typically happens on the onset of mental illness. In a society where people lives get ever more confused with their occupation, stress at work can sometimes trigger a tragedy. The numbers don't lie. According to researchers at the National Institute for Occupational Safety and Health 1,700 people died by suicide on the job between 2003 to 2010.
