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.
Buzz Aldrin, the second man on the moon, is no stranger to staggering photos. His most famous shot includes the first ever selfie in space. Now, while visiting Stonehenge, Aldrin posted on Twitter a photo of him sporting a t-shirt with a stylized Mars logo a la NASA, which read "Get your ass to Mars". A long time supporter of inter-planetary exploration, both publicly during his numerous TV appearances or press editorials and institutionally during his stints in front of Congress, this latest publicity shot aims to inspire the public and garner support for a manned mission to Mars.

The conservative Canadian government headed by Prime Minister Stephen Harper has consistently moved the country away from sustainable practices and environmental accountability. In 2011, the government came under fire after it withdrew Canada from the Kyoto protocol, an international agreement which commits its parties by setting internationally binding emission reduction targets. It also disbanded the National Round Table on the Environment and the Economy in 2012, a panel tasked with reporting to the government Canada's greenhouse gas emissions. While the government has also taken some measures aimed at curbing emissions, these have been largely insufficient. Disappointed, 71 Canadian scientists have authored their own climate policy recommendations for the nation.
Mudskippers are a strange type of fish - for starters, they're amphibious, which means that they spend a great of their time on land. They also have unique adaptations which allow them to manage in the intertidal environments in the Indo-Pacific and the Atlantic coast of Africa. Their unusual feeding behavior has now been captured in high-speed and X-ray video by biologist Krijn Michel and his colleagues at the University of Antwerp, shedding new light on how life moved from the oceans onto the land.
They're considered a hybrid between asteroids and comets, but still, they're called minor planets; they also bear the name of the fabled man-horse creatures in Greek mythology - centaurs. Now, scientists have found that a Centaur in our solar system, Chiron, might have rings just like those of Saturn.
Designer Thomas Heatherwick just completed construction on a cluster of 12 parsnip tornado-shaped towers for the Nanyang Technological University in Singapore. The building, called the Learning Hub, is part of a larger project to help redesign educational architecture and make the university a more attractive place. I have to say, it seems to be working – it’s one of […]
Some 17 million years ago, a beaked whale took a wrong turn up an African river, something which ultimately proved to be its demise. But now, geologists studying the whale's fossils believe the whale's unfortunate end might shed a new light on early human evolution.
A rather surprising study found that graphene's imperfections can actually be used to improve fuel cell efficiency. Researchers from Northwestern University worked together with scientists of five other institutes to show that defective graphene actually works as the world's thinnest proton channel—only one atom thick.
In a rather intriguing tweet, Tesla Motors and SpaceX CEO Elon Musk announced that he will end 'range anxiety' by the end of the week for the entire S series. The electric Tesla Model S is already able to travel up to 265 miles before its battery runs out of power – one of the longest driving ranges of any electric car currently on the market. Now, it seems they are preparing to take things even further.
According to Danish and Australian researchers, there are billions of the stars in the Milky Way located in the "habitable zone", where liquid water might exist, and with it, life as we know it.
Half cockroach, half machine, these peculiar insects were hijacked by researchers at Texas A&M University for science. Electrodes implanted in their tiny brains send electrical signals that stir the roaches left, right or makes them halt. Effectively, the researchers are controlling their bodies. This may sound despicable - it actually is in many ways - but the benefits to humanity are far reaching. The cyborgs would be our eyes and ears in places otherwise inaccessible, like disasters sites in the wake of earthquakes or other environmental calamities. Picking the cockroach brain might also help us learn more about how our own brain works. This in turn could spur the development of brain-computer interfaces or a new generation of prostheses that faithfully mimic real limbs.
A new company called Carbon3D, founded by a team of physicists and chemists, were inspired by the iconic Terminator villein, the self-morphing T-1000, to build a machine that 3D prints objects from a puddle of raisin. Unlike conventional 3D printers which add material layer by layer, the latest innovation works fundamentally different. The models it prints are extremely sophisticated and detailed, making it a valuable tool for consumer products, not just prototyping as is the norm today.
About two dozen University of Texas students gathered on Saturday at the entrance to the SXSW tech and entertainment festival to voice their concerns about the risks artificial intelligence might pose to humanity. Though largely ignored by hipster pedestrians nearby, the protest does raise some legitimate concerns even though technology is still far off from any Skynet scenario. Thankfully, we might never cross this SciFi threshold.
A year ago, Oxford University professor of human genetics Bryan Sykes and his colleagues took some unusual hair samples found in the Himalayas and concluded that they actually belong to a now extinct polar bear which once inhabited Norway. Now, another team analyzed the results and concluded that while it's clearly no yeti, the remains might actually belong to a brown bear instead.
Researchers from NASA, Imperial College in London and Texas University have discovered two seafloor troughs that allow warm ocean water to infiltrate and accentuate the melting of Totten Glacier, East Antarctica's largest glacier. This could have massive implications not only for the Antarctica ice, but for global sea levels.
Some 480 million years ago the seven-foot-long Aegirocassis benmoulae swam in a shallow sea covering what is today the Sahara desert. This giant arthropod, much larger than arthropods existing today, was likely the biggest creature in the world at the time.
Researchers at Brown University have found a cheaper and easier way to create hybrid perovskites, enabling engineers to develop more affordable and efficient solar cells. Perovskite is a calcium titanium oxide mineral composed of calcium titanate (CaTiO3). The mineral has received much attention in recent years as artificial perovskite crystals have increasingly been used in solar cells. Perovskite films in solar cells are excellent light absorbers, but they until now, they were more expensive to fabric and only created small crystals.
There are still many things we have yet to discover about plants, a new study has highlighted. The research team showed that trees don’t just move water up and down like we previously thought - they can store it and move it horizontally if they need it. In a way, they save water for a not-so-rainy day.
