Yesterday, we wrote about how the Chinese will be selling genetically engineered micro-pigs as pets; the pigs, which were originally developed to serve as cheaper models for the human body, were engineered to grow only up to 25 kgs, but they also raise some important concerns: is it ethical? Should we engineer animals so that […]
While everyone from Google, to Tesla, to BMW is engineering driverless cars, gearing up for an impeding auto revolution, a Chinese company went directly for a niche market: driverless buses.
Publication bias strikes again: because only positive results are published in scientific journals, medical literature greatly overstates the benefits of talk therapy for depression.
After the recent Volkswagen fiasco which revealed that their cars emit much more than they should (and claimed), a new study revealed that diesel cars made by Renault, Nissan, Hyundai, Citroen, Fiat, Volvo and many others also emit more.
The Scandinavian nation has set its mind on ridding itself of fossils fuels. To this end, the government announced it will increase spending on climate-protection measures for the next year bringing it to $546 million. That might not sound like much but Sweden is a small country which already uses energy very efficiently. It also gets three quarters of its energy from non-fossil fuel sources, mainly nuclear and hydro.
When it comes to human waste products and pollutants, plastic claims the crown. There are very few things our planet can throw at it to get rid of the polymer. It becomes bendy and rippy and shredy but it just won't go away. When you compound the resilience of this headstrong material with the sheer quantities of it that we dump into the oceans, it looks like a pretty one-sided battle that nature can't win, despite all our desperate efforts to increase recycling and take it out of landfills. But now it seems that mother nature still had a trick up her sleeve, and the non-biodegradable reign of plastic is about to come to an end, undermined by the heroic appetite of the mealworm.
Drivers and passengers who light one up while kids are in the car now face fines in England in Wales, in an attempt to curve down the effects of passive smoking.
Further increasing their conservation efforts, New Zealand will develop the world's largest oceanic sanctuary - twice as big as their entire country.
In what can only be classed as a breakthrough in medicine, a team at Washington University in St. Louis found a way to make an universal test that can identify virtually any known virus. The method works by analyzing bodily samples for signature genetic markers unique to each virus. It's surprisingly accurate, as the researchers report the test not only identified the viruses on par with standard tests, but found additional ones which would have otherwise gone unnoticed. Once it passes extensive clinical trials, doctors using the test could come up with a complete list of viral infections harbored inside a patient's body, correctly diagnose their condition and apply the right treatment. In some situations, it could mean the difference between life and death.
At the European Planetary Science Conference in Nantes, France, NASA presented some spectacular maps and observations about Ceres, the largest object in the asteroid belt, and the largest of the minor planets within the orbit of Neptune. Astronomers analyzed data coming from the Dawn spacecraft, which entered orbit around Ceres on 6 March 2015.
Enticed by warming waters, king crabs might soon make a run for Antarctica's continental shelf where they haven't been seen for at least 10 million years. As such, the fragile wildlife comprised of creatures like sea stars, sea worms, sponges, sea anemones, sea lilies and feather stars - all lacking protection against the crushing claws of the king crab - could face rapid annihilation.
When there's rain, let alone a storm, city streets form puddles and in some extreme cases get flooded. That's because concrete mostly keeps water out, and only a tiny volume gets absorbed. A company from the UK, however, has come up with such an innovative solution that it almost seems like magic were it not pure science at work. Namely, they came up with a new kind of concrete that allows more water to percolate through its gaps, so much that 1,056 gallons were gobbled up in under 60 seconds during a test. It all seems unreal - but it's as concrete as it gets.
Many researchers have expressed concerns about using such advanced techniques for such frivolous purposes, and personally, I feel like this could cascade onto many other problems - despite their undeniable cuteness.
A new study conducted on medical consumption of cannabis came up with some good news, and some bad news: for starters, while there were some adverse effects on consumers, no serious effects were reported. However, the reduction in pain also seems to be very small.
The word on every tech executive's mouth today is data. Curse or blessing, there's so much data lying around - with about 2.5 quintillion bytes of data added each day - that it's become increasingly difficult to make sense of it in a meaningful way. There's a solution to the big data problem, though: machine learning algorithms that get fed countless variables and spot patterns otherwise oblivious to humans. Researchers have already made use of machine learning to solve challenges in medicine, cosmology and, most recently, crime. Tech giant Hitachi, for instance, developed a machine learning interface reminiscent of Philip K. Dick's Minority Report which can predict when, where and possibly who might commit a crime before it happens.
In front of hundreds of guests, Tesla's CEO, the ever resourceful Elon Musk, unveiled the company's new model: the Model X crossover. It's been a long heralded and waited vehicle, and it sure didn't disappoint. This beauty, all dressed in white, looks more like a bird than a car with its upward-opening "falcon doors". It also flies like one, reaching 0 to 60mph in 3.2 seconds making it the world's quickest SUV. Wait 'till the kids see it.
Six years ago, at the 2009 climate talks in Copenhagen, things seemed to have taken a dire turn, with no solution in sight. Basically, no one really wanted to pledge anything significant. But then, Hillary Clinton, then secretary of state, brought forth a proposal.
Despite manufacturers have tirelessly designed new types of razor blades for a cleaner shave, the process has stayed virtually unchanged for thousands of years. The difference between a modern razor blade and an ancient roman shaving knife isn't that large, on a fundamental level at least. This may set to change if the Skarp Laser Razor makes its way into the shaving kit market. The gadget is basically a high-tech razor - named so only by function - that uses a highly focused laser beam instead of a blade.
Paleontologists believe they have found the oldest evidence of the bubonic plague, embedded in a flea trapped in amber for the past 20 million years. This could provide insight onto how this devastating disease appeared and evolved.
Two days ago, NASA made a spectacular announcement: they found liquid water on Mars, confirming suspicions and clues from years ago. But while they make a compelling case for the water, it would still be better to examine it on the spot, except there's a slight problem with that: NASA can't immediately investigate the water on-site, using the Curiosity rover or anything else, because it's bound by international treaties.
"Hey, what did you find" "We found a bio-florescent turtle!", a researcher triumphantly declared. David Gruber, a biologist at City University of New York, and colleagues made the find while diving in the Solomon Islands this July. Previously, researchers have found ever growing evidence of bio-luminescence and bio-fluorescence in the animal kingdom, from coral to seahorses, but this was the first time anyone has laid sight on a glowing reptile.
Even though wages today are higher than they were in the '70s, after you account for inflation these are only marginally better. At the same time, productivity has almost doubled according to a reported issued by the U.S. Census Bureau. In other words, despite the economy has significantly grown in the past 40 years, American workers got a pay cut - not a raise.
North Carolina State University researchers have succeeded in proving that the crystalline structure of a material can be formed by disorder at an atomic level and not chemical bonds, by creating the world's first entropy-stabilized alloy incorporating oxides.
Our ability to inhibit impulsive behaviors, to exercise willpower, is considered a core feature of the brain's executive functions. This, along with others such as reasoning, working memory and attention regulate our thoughts and guide our behavior, allowing us to adapt them to the changing demands of our environment. But the effort our brain puts into refraining from impulses is so great that it can actually diminish its ability to form memories of the experience.
Fewer materials in nature rival the toughness and resilience of a tooth or a seashell, and it's all due to their unique structure; viewed under powerful enough microscope, they reveal layers upon layers of micro-plates, perfectly aligned and fused together. Material scientists have long sought to produce something that imitates these structures, with comparable properties and complexity, but apart from nacre (mother-of-pearl) they've had very little success. Until now.
Endemic to Andes Mountains of Chile, Argentina, Bolivia and Peru, the Andean Cat is one elusive feline. It's only been sighted a couple times in the wild, let alone photographed. Some researchers were lucky though after their camera traps photographed a gem: an adult and her kitten.
During an extraordinary conference hosted by NASA, a team of researchers report that flowing briny water is flowing out of Martian mountain slopes. Let that sink in for a moment. Now, time to pull yourself together and check out some more details.
After they analyzed more than 2,000 traditional Indian recipes down to the molecular levels, scientists now think they know what makes Indian cuisine so appealing. Unlike western dishes, Indian recipes are based on ingredients whose flavors don't overlap for a unique taste that dumbstrucks anyone who tries it for the first time.
Another boost for India's low-cost, but extremely promising, space program took place this morning after the country launched its first space observatory in space. Blasting from the spaceport of Sriharikota, close to Chennai, the Astrosat telescope was deployed without any difficulties in Earth's orbit, some 650 km above. Along with it, some six satellites piggybacked, four belong to the US, one to Canada and the last to Indonesia.
A 30KW high-power laser was demonstrated by Lockheed Martin after it was used to disable a vehicle more than a mile away. One of the great perks of laser weapons is their phenomenal accuracy. To showcase this, the weapon was directed specifically on the hood of the vehicle, where it fried the engine. The beam from the Advanced Test High Energy Asset, or ATHENA, is believed to be most powerful ever documented in a laser weapon.
The ancient Greek shipwreck that produced the awesome Antikythera mechanism, hailed as the world's first analog computer (being almost two millenia old), had archaeologists' collective pants full of ants and it seems that their enthusiasm was well placed. The shipwreck is slowly yielding new artifacts, offering a glimpse into the lifestyles of the ancient "1%" in the Hellenic peninsula.
Each memory relies on three critical elements, those being the "what," "where" and "when" building blocks. Neuroscientists from MIT have identified a brain circuit -- connecting the hippocampus and a region of the cortex known as entorhinal cortex -- that handles the "when" and "where" components.
A new paper published Thursday in Science looks at how climate change is (out of all things) making the tongue of some bumble bees shrink. Two species of alpine bumbles in the Rocky Mountains already show a decrease in tongue volume of nearly 25 percent in the last 40 years; and smaller tongues could spell big trouble for the flowers that rely on bumble bees for pollination.
Deep in the Arctic, nestled inside an icy island lies one of humanity's backup plan: the Svalbard Global Seed Vault. Open in 2008, the center houses seeds from virtually all the plants on the planet be them wild, domesticated or genetically modified. In case of a global calamity of any kind (nuclear war *cough), these seeds would be put to good use if a species is faced with extinction or research is required on such seeds. This is precisely why the first withdrawal request from the vault was made by Syrian researchers.
A couple of quadrotors wove a bridge out of polyethylene fiber rope in an intricate dance. Some 120 meters of rope were used by the quadrotors to bridge the 7.4-meter gap, neatly tying knots, links, and braiding. Ultimately, the final test was passed after an ETH Zurich’s Institute for Dynamic Systems and Control student crossed the robot-manufactured bridge.
I love disruptive technologies, and 3D printing is undoubtedly one of the leading such movements in the 21st century. This kind of tech will democratize manufacturing, moving it away from 3rd world sweatshops to your own garage. And no, you don't have to be a geek to own one. Ten years from now, it should be as easy to use and as widespread in homes as a regular ink printer. But for now, 3D printing is limited, particularly as far as electronics are concerned. Usually, you have to print the plastic parts, then order electronic parts like circuits, chips or motors, before finally assembling it all together yourself. You can't have a global manufacturing revolution if you need to be a lab wiz to print a new TV remote control to replace the one the dog just shred to pieces. But this is all changed. We're just now seeing the first steps that might one day lead people to print their own smartphones.
University of Washington researchers have created the first telepathic link between two humans. Their technique didn't rely on supernatural powers, but rather on nerve impulses, electrodes, and advanced science.
The Great Barrier Reef, which stretches 2,000km (1,200 miles) along the coast, is the world’s largest living ecosystem. Yet it's being threatened and every year the coral retreats at the hand of pollution, tourism, farming and pests. One such pest is the crown-of-thorns starfish which attaches itself to the coral and destroys it with its venomous thorns. Various pest control measures have been tried, but none proved more effective than injecting the animals with vinegar. James Cook University researchers tried out various concentrations of vinegar, needle size and injection locations until they found the sweet spot for a 100% kill rate within 48 hours of contact. Widespread and sustained (you have to control the starfish every year following breeding season) could thus help save the Great Barrier Reef, or at least buy time until we address the more serious causes leading to its destruction.
California is currently experiencing its worst drought in over a millennium. Trillions of gallons of underground waters were lost in 2013 alone, and things are not looking up. Now, a new study has found that not even giant sequoias, majestic trees that have been living for centuries, are safe from the effects of this drought.
Enamel, the hard, mineralized substance that covers your teeth originated on tough fish scales and then migrated to the teeth, researchers found
A while ago I wrote about how the fossil fuel divestment movement is gathering a huge momentum, as more and more funds, universities and companies are choosing to migrate their financial assets away from fossil. The movement is spearheaded by Bill McKibben, one of the founders of the 350.org group, who first organized rallies and lobbied key partners. "Almost from the start, academics have called it the fastest growing such anti-corporate campaign in history, and it’s clearly accelerating by the day,” said McKibben. But I don't even think McKibben himself predicted how far divestment would go. It was launched more like an awareness campaign on the dangers of global warming. It's grown fast, for sure, but this fast? Let me run some numbers: according to a report released by Arabella Advisors, $2.6 trillion in assets have moved away from fossil portfolios or 50 times more than last year. That's not just a dent anymore - that's serious cash!
Specialists from the University of Cambridge and the University of Colorado estimate that the effects of climate change are going to take a hefty toll on our economy -- $326 trillion in damage by the year 2200, roughly $201 million each hour, the Christian Science Monitor reports.
New research suggests that simply fidgeting around could counter some of the effects of sitting down for too long.
For the first time, Japanese researchers have successfully grown a pair of kidneys in a lab and then transplanted them into animals. The organs functioned just fine, and this gives big hopes for the transplants ultimately moving to humans.
No kidding, Stanford researchers actually showed it's possible to cool solar panels by applying a special coating that reflects some of the heat back into space. The coating, called a photonic crystal cooling system, is transparent. This allows the light to reach the PV cells so these can generate energy, but - crucially - some of the heat is reflected back in space. It's so good that the researchers showed their PV panels can even stay below ambient temperature, which is incredible by itself. If you know a thing or two about solar panels, then you'll remember their efficiency is directly related to temperature. The cooler a panel is, the more of the sun's energy it can convert into electricity. And we're talking about a mere coating, which shouldn't be too difficult to scale. Bit by bit, you if you multiply the extra efficiency by millions of panels you end up with a huge useful energy gain. This may be a game changer.
Scientists working at the Paul Scherrer Institute (PSI) have created a very specific type of material from over 1 billion magnets placed in a specific configuration. Astonishingly, its magnetic properties now change with temperature, just like water can be liquid, solid and gaseous based on temperature.
A group of scientists working at the National Institute of Standards and Technology (NIST) has managed to successfully transfer information from on proton to another one 100 kilometers away (60 miles). This could ultimately lead not to actual teleportation, but rather to unhackable conversations.
Take a candle, light it, turn it on its side -- we all know what will happen. The convection cell that forms around the flame keeps licking up towards the sky (or ceiling) regardless of the orientation of the fuel. But can the movement of air be overcome, can we make a fire burn horizontally? Well, the short answer is yes, yes we can -- we just have to use science.
Some researchers have made an interesting connection: if you measure the complexity of life or how big the genome is you find it increases at a rate that seems exponential. It's very similar to Moore's law, which suggests the number of transistors over the same surface area on a chip doubles almost every two years. You can extrapolate both forward and background. Eventually, if you extrapolate down enough you'll find the point of origin. In other words, it's possible to estimate when life first appeared based on life's complexity graph.
