Mindset and learning go hand in hand. It's important to be confident in one's own abilities to learn new skills and meet goals. Overconfidence, however, can also hinder learning according to Washington State University researcher Joyce Ehrlinger.
Anxious people may be more prone to associate neutral environmental cues with emotional experiences. Psychologists call this over-generalization, and research into the matter might explain why a seemingly minor event can sometimes unleash a full blown anxiety episode. We might also learn more about the wiring of the anxious brain which fires in different patterns than the 'normal' brain.
A study made by researchers at Forida Atlantic University and Cleveland State University assessed the effects of paid sick leave, or lack thereof, had on employees' health. Those who didn't have this benefit were at a much greater risk of forgoing medical care, either to treat or prevent an illness or injury.
An artificial ‘skin’ can stretch up to 480 percent its original size, and can sense changes in pressure – a haptic feature that could lend both robots and human prostheses a sense of touch.
Around 65.5 million years ago a 10-km wide asteroid crashed into the Yucatan Peninsula in Mexico, suddenly altering all life on the planet.
Recently, a treasure trove of a dozen ancient lizards trapped in amber came to scientists' attention. Everyone was impressed by the pristine preservation, but what particularly caught their eyes was a chameleon-like creature that's 100 million years old. That's 78 million years older than the previous record holder.
Seals from colonies on the North Atlantic island of North Rona that had higher levels of the hormone oxytocin in their blood stay closer to pups. This suggests that the hormone, often called the love hormone because of its role in love and in female reproductive biological functions, is paramount to forming mother-child bond.
Mars was never the same after a monster volcano erupted on the Red Planet some 3.5 billion years ago. Before the massive eruption, its poles were in completely different locations, so where it rivers and ice sheets. Moreover, the crust buckled and twisted in alien ways, like the skin and flesh of a peach shifting in relation to its pit.
An early land lover, the Tortobu might have been a key part of the land ecosystem that eventually grew to foster complex land life.
Using only five atoms, a team of international researchers showed how to factor a prime, albeit a trivial one for demo purposes.
Up until now, there was no reliable way to measure the temperature of nanoscale objects, like viruses.
A revolutionary new supercomputer powered by Adenosine triphosphate (ATP), the energy source for every living cell in your body, is ridiculously small and much more efficient than a traditional supercomputer. That's because instead of electricity, this computer is powered by biological agents. This means it needs little to any cooling, and can be scaled to the size of a book.
Wind gusts are so unforgiving that the trees themselves molded into weird and crooked shapes. There's an almost surreal beauty to their shape, though -- it brings harshness to life. You won't find anything like it anywhere else in the world.
Dammit, people!
Evidence points to the fact that Neanderthals used manganese dioxide, today commonly found in batteries, to light fires some 50,000 years ago.
This week Hollywood actor Leonardo DiCaprio won his very first Academy award for best actor. Of course, he was there and took the stage for his acceptance speech. What happened next didn't surprise those familiar with DiCaprio's concerns outside the movie business: he spoke about the imminent threat of climate change, calling it ‘the most existential crisis our civilization has ever known.’
In neighborhoods with high crime rates, past research showed that women who perceive they are at risk will generally be attracted to physically formidable and dominant mates (PPFDM). Yes, I know, it's a hilarious classification. But while this finding isn't all that surprising, there's a new research by a team at University of Leicester, UK which suggests this is true even when there isn't much or any risk of physical confrontation at all. In other words, women who feel vulnerable or victimized no matter the circumstances will find comfort in dating PPFDM (now you have a new shorthand to call your meatier friends; enjoy!).
Many consumers now choose to exclusively buy products labeled with an eco-certificate which supposedly testifies that manufacturing was made in sustainable manner. Do these actually work? One of the few studies on the subject seems to suggest that the impact is positive, at least in Chile and related to deforestation.
Fewer guns lead to fewer homicides. Will this convince anyone in the U.S., though?
In the 1990s, a famous study found animals in Yellowstone National Park, like elk, bred in fewer numbers and ate less after wolves were re-introduced. That seems like something bound to happen when you introduce an apex predator in a new ecosystem. However, what the study pointed out, in fact, was that most of the elk population suffered not as a result of attack from wolves, but rather simply due to them knowing wolves where now sharing the same park. In other words, fear produced such intense ripples that it altered the entire ecosystem. This was very controversial, and a team of Canadian researchers sought to replicate the findings on an island of fearless raccoons.
One group combined water collecting traits from the awesome Namib desert beetle, cactus and pitcher plant to devise a material that seemingly makes water out of thin air.
DiCaprio took to the stage to present his acceptance speech, and tackled climate change in front of millions of people watching the Academy Awards, calling it 'the most existential crisis our civilisation has ever known.'
There's a tune to oxygen, carbon and any other element from the periodic table.
If you sprinkle water on a hot plate, it will evaporate. Basic physics, really. If the plate is really hot (well above the boiling point of water) something very interesting happens, which the untrained eye might discard as uneventful. The droplets will dance around the plate on a cushion of its own vapor -- this form of levitation is called the Leindenfrost effect. This layer is about 100 nanometers wide, and for the first time a team of researchers has imaged it.
Research shows that those who exercise stand a far better chance of not getting getting cancer. Those who did get cancer, but recovered, can delay or completely avert cancer from showing up again by putting in hours in the gym.
Human psychology works in surprising ways, due to our inherent biases. Stubborn people are always hard to convince, but researchers have identified some of the points that sometimes cause people to change their minds about something.
Clearly, this isn't your regular truck. It's a custom build that allows masons to erect free-standing tunnels very fast. The roller-covered arched rear temporarily supports the Lego-like brick structures, which are then locked in place without the need for an adhesive.
University of Washington researchers want to flip Wi-Fi energy use upside down. They've invented a new protocol and technique that uses 10,000 less energy. The same signal can be used to power devices without the need of an external power source. Cameras, temperature or motion sensors can all be power and connected to the internet at the same time using 'passive Wi-Fi.'
Pushing around Atlas actually has a purpose, besides annoying the robot.
Depending on the alignment of Mars and Earth, as well as the speed of propulsion, a spacecraft could reach the Red Planet as soon as 150 days. So far, NASA spacecraft have made 13 trips to Mars, with seven landings. The most recent -- that of the Curiosity rover -- took 253 days from launch on Earth to touchdown on Mars. There's now reason to believe, however, that this journey could be significantly made faster to the point it only takes 3 days, according to a NASA researcher.
Can you fly through water? It's a silly thought, but that's exactly what this snail butterfly, called Limacina helicina, seems to be doing. Researchers at Georgia Tech report that these sea snails flap their wings in a figure eight pattern very much akin to that used by airborne insects, like flies or bees.
For the first time, natural gas installations were also surpassed by PV arrays despite the shale boom, which says a lot about the momentum solar energy is currently gathering.
A study ten years in the making found that sea levels are rising at the fastest rate in the last 2,800 years. The researchers say that greenhouse gas emissions that build up in the atmosphere and heat the planet, melting glaciers and ice sheets, are to blame for this sharp rise.
Two major oil spills in the course of only one month are threatening Amazonian wildlife and local communities. Peru’s General Directorate of Environmental Health issued a water quality emergency last Wednesday, but critics voice that this is a tad late -- more than three weeks since the first spill spewed more than 2,000 barrels in the regions of Amazonas and Loreto. Shockingly, a third spill has been reported by the local media in Peru, but this has been refuted by the the oil company responsible for the pipelines.
Astronaut Scott Kelly (seen in pic) and his colleagues stationed on the International Space Station now have a new Sidekick. The project is a collaboration between NASA and Microsoft aimed to help with astronaut duties, like repairs, experiments or space walks, using an out of this world augment reality device called the HoloLens.
Sharks have a reputation of solitary predators. They're not the life of the party, sort to say. One new research casts doubt on this assumption, though. The findings suggest that sharks, or at least Sand Tiger sharks, have a complex social structure not all that different in some instances from notoriously social mammals like dolphins, chimps or even humans.
While 3-D scanning the Columbia command module used by the Apollo 11 astronauts to splash down back on Earth, researchers found some amazing artifacts: graffiti markings.
This suggests that humans and Neanderthals interbred about 50,000 years earlier than previously thought. The implications are staggering considering humans left Africa to settle Europe and Asia about 65,000 years ago. How was this possible? Researchers suggest that this gene flow comes from modern humans who left Africa even earlier -- maybe the very first wave.
A four-minute cantata was found among the the mountains of archives in the Czech Museum of Music in November 2015. The score was likely written in 1785 by the maestro Wolfgang Amadeus Mozart, along with Antonio Salieri, popularly considered a rival, and an unknown composer called Cornetti. The find was made after Timo Jouko Herrmann, a German composer, was browsing […]
Such a program might prove effective at training simple robots to be less awkward around humans and, most importantly, make sure they don't hurt anyone or break social norms.
Part of NASA JPL's Exoplanet Travel Bureau series, these 14 posters show such locales as Mars, Jupiter's moon Europa, Saturn's vapor-spewing moon Enceladus, and the dwarf planet Ceres. They're all available for free in massive resolution (PDF and TIFF format), so you can download, print and hang in your living room. Enjoy!
This quartz disk could revolutionize storage.
Between 2,500 and 4,000 so-called 'extremists' have been killed by drone strikes and kill squads in Pakistan since 2004. Maybe as early as 2007, the NSA has targeted terrorists based on metadata supplied by machine learning program named Skynet. I have no idea who would find naming Skynet a machine designed to list people for assassination a bright idea, but that's besides the point. The real point is that the inner workings of this software, as revealed in part by Edward Snowden from his leaks, suggest that the program might be targeting innocent people.
Today, sea levels rise at a rate double that recorded in the 20th century. That's a lot, but not nearly as much as climate scientists expected. Researchers at NASA claim they now know why: thirsty continents absorb a great deal of the extra water coming from melting glaciers. They warn, however, that the system will become saturated at one point and the water will be returned to the oceans, as part of the global water cycle.
A rare kind of aphasia, abbreviated PPA, leaves people at a loss for words. Patients blabber and stutter, seemingly unable to communicate. Often times families think their diseased relatives and loved ones have Alzheimer's. Because primary progressive aphasia is so rare and unknown, even doctors often misdiagnose the disease. Upon closer inspection though, the PPA patient clearly is able to understand questions and reason . It's just they simply can't verbally use words. At a recent meeting of the American Association for the Advancement of Science, PPA has been put in the center of discussion to raise awareness but also share some of the most promising therapies.
Our perception does not always reflect reality, as evidenced by numerous studies. The information sent by the eyes to the brain is processed and contains many short-cuts and assumptions which makes things more optimized, but also leads to biases. One study, for instance, found that people who are overweight will judge an object as being farther than it really is. This suggests that physical characteristics -- people who thought they were overweight, but weren't in fact, did not share this bias -- plays a major role in defining perception.
To find its way home to the nest, a wasp will leave its own visual 'breadcrumps'. The wasp will ever so often fly backwards to see its environment as if it were traveling to the nest, and use this information later to make its way safely back.
There are over 5,000 mineral species identified by scientists thus far, but fewer than 100 make up the entire planet's crust. The rest are so rare, short lived and notoriously difficult to replicate that you'd barely know they're here. Not understating the importance of such minerals -- which could offer clues on how the planet formed, but also lead to new industrial applications -- researchers from the United States cataloged the 2,500 rarest minerals on the planet.
Though technically a metal, the electrons inside graphene behave like a liquid traveling very fast in waves.
Today, some people are freezing their bodies or heads at death in hopes of future cures for what ails them. Alas, these people are likely gone forever because the damage to the brain is far too critical. With this in mind, despite an enthusiastic decade in the '80s for cryonics, the field has been rarely touched by serious scientists. A group of researchers may spark interest again after they report freezing rabbit and pig brains, then returning them from preservation apparently in mint condition as if they were never iced. This lends hope that just maybe it would be possible to do the same for human brains just before the person dies, and thaw it in proper working condition when the tech is there to revive them.
