Each year, hundreds of millions people fly by plane to meet family, do business or travel for leisure. Quite a feat, considering humans don't have any wings. Like all advanced technology we have at our disposal today, flying is also taken for granted. In the early days, however, just getting a few feet off the ground for a couple of seconds was considered a triumph. Like human pioneering flight, nature also had to experiment a lot before flying creatures could evolve. One newly discovered dinosaur species fits well into this story. Unearthed in 160 million year old sediments in China, this queer dinosaur strangely had bat-like wings. It's uncertain however if it was able to fly or even glide, owing to the degraded state of the fossil records. One thing's for sure, it makes the evolution of flight much more interesting to study.
Boom!
Childhood bullying seems to be almost ubiquitous to some extent, and yet researchers have time and time again underlined the negative effects it can have. Now, a new study has concluded that kids who were bullied by their peers suffer worse in the long term than those who were maltreated by adults. The research was […]
Each year, we cut down 26 billion trees, for lumber, agriculture, mining and development projects. Every year, we plant about 15 billion trees, so that still leaves us with a huge deficit - something which is not sustainable and has to be addressed as soon as possible to avoid further problems down the road. Now, a former NASA engineer has found that drones could play a key part, and he plans to plant up to 1 billion trees a year using them.
Drug-resistant bacteria are one of the biggest challenges mankind has to face in the near, as well as distant, future. In a recent survey conducted by the World Health Organization it was revealed that only 34 out of 133 questioned countries have even a basic plan to combat the misuse of antibiotics fuelling drug resistance and encouraging the development of superbugs.
IBM claims to be one step closer to developing functional, scalable quantum computers. According to the company, they managed to overcome two key hurdles, demonstrating for the first time a new, square quantum bit circuit design - the only physical architecture that could successfully scale to larger dimensions.
A coast guard patrol reported that Lake Michigan’s shallow waters are so clear that you can actually see the shipwrecks on the bottom of the lake, until sediments stir up the water and algae blooms develop. Lake Michigan is one of the five Great Lakes of North America, and the only one that’s completely on […]
Using three state of the art ground-based telescopes, a team of astronomers has identified three super-Earth exoplanets that are seven to eight times as massive as our own planet and orbit their parent star closer than Mercury orbits the sun. What's hot about the findings - apart from the planet's likely scorching surface - is that these were made using a novel automated approach, in which one telescope called the Automated Planet Finder (APF) Telescope at Lick Observatory in California was programmed to scour the night's sky and look for signs of nearby alien planets. These three planets are just the beginning of a new process that hopefully will return hundreds of planets in our neighborhood, all without the need for human supervision.
You hear about potential cancer treatments all the time, and despite significant and remarkable improvements, we're still miles away from an actual cure for cancer; so what makes this therapy so great? Well... it just seems to work - on humans, suffering from cancer, not in a lab. For one woman, it seems to have completely dissolved a big tumor in just three weeks, and overall, 53% of patients experienced at least 80% tumor shrinkage.
While humans have invented a convention called time keeping to make society work, our bodies themselves also have a sort of clock called an internal biologic clock or circadian rhythm. When met by daylight, hormones are released that keep us awake and alert, while darkness releases different hormones that puts us to sleep. Canadian researchers have now found the molecular switch that resets and synchronizes the circadian clock. A drug that tweaks this switch could thus be made that regulates the internal clock, something travelers and night owls might find particularly useful.
All those hours of leveling up your character have finally paid off - a new study conducted by Australian and Chinese researchers suggests that playing computer games not only increases the amount of grey matter in your brain, but also promotes better connectivity between different areas of the brain.
A report issued by a committee at MIT concludes that the decline in science funding will have drastic consequences for the country's economy and security, making the US trail behind other countries like China which is spending immense amounts of money on science. In fact, one study estimates China will become the world's leading science and innovation producer by 2020, outpacing the US. The MIT report identifies some 15 fields where inadequate budgets seriously hampers progress, from Alzheimer's research, to nuclear fusion, to disease and agriculture.
An innovative study suggests that something as small as labeling healthy foods with a small smiley face can make kids more interested in buying and consuming healthy food.
Researchers from Cambridge have, for the first time, captured a 3D video of a living algal embryo turning itself inside out: from a sphere into a mushroom and into a sphere again. The results could help us better understand the process of gastrulation in animal embryos -- which biologist Lewis Wolpert called "the most important event in your life."
Endemic to Australia and New Zealand, the satin bowerbird is considered one of the most intelligent birds found in nature. Mature males are very easy to spot because of their bright blue eyes, while their bodies are uniformly covered in black, although sometimes light diffraction makes the bird's feathers turn almost into a metallic sheen. What sets these birds apart is their remarkable courtship ritual, and the male's seemingly obsessive fixation for blue.
Just after NASA researchers made the bold claim that they will find alien life in less than 20 years, the space agency has officially launched a project to look for it. The Nexus for Exoplanet System Science, or “NExSS” will be a project integrating several fields of science, aiming to better understand exoplanets with the potential to host life, as well as planet-life interactions.
The rate of global warming varies from year to year, and climate change deniers try to take advantage of this and argue that global warming is actually slowing down. That may or may not be true, but Earth is still on course for extremely dangerous levels of warming, and, as yet another study has concluded, this is also causing extreme weather.
A seven year old has discovered the fossil of a turkey-sized dinosaur that roamed South America over 140 million years ago. The tiny dinosaur was related to T-Rex, but had few similarities to it; aside for its size, the dinosaur was a vegetarian, munching on plants instead of terrorizing other creatures.
Good news for space exploration: Japan’s space agency JAXA revealed plans to land a rover on the Moon by 2018, joining a very small club of nations that directly explored our planet’s satellite. “This is an initial step and a lot of procedures are still ahead before the plan is formally approved,” a JAXA spokesperson told […]
We all need to consider our future without pollinators, or if there even will be a future without them.
We all see garbage in our daily routine, be it on the way to work, school, or just on the streets. But most people just choose to ignore it; after all, what difference could one man possibly do? Well, Tommy Kleyn didn’t think like that when he was walking pass a polluted river to work. He […]
Beneath one of the most famous touristic attractions in the world, the Yellowstone National Park, there lies one of the largest and most complex volcanic systems in the world. Yellowstone is a supervolcano of perplexing size, but as Utah seismologists found... it may actually be even bigger than previously thought.
We've all had days when we've felt invisible metaphorically, but Swedish researchers have taken it to the next level - they've made a man actually feel like he's invisible.
While searching for the remains of an ancient human ancestor, archaeologists came across a lot more than their bargained for: the oldest stone tools ever found so far. The archaic stones they found were clearly deliberately manipulated by hominid hands, and not the result of some natural formation. According to paleomagnetic dating techniques, the artifacts are about 3.3 million years old, or 700,000 years older than previous artifacts.
According to the Department of Energy, the plutonium-238 stockpile is enough to make only three more nuclear batteries. These are used to power long-term space missions, like Curiosity rover now studying Mars on site, the Voyager probes which were launched in the 1970s and are now almost out of the solar system or New Horizon which is close to making the first Pluto flyby in history. New Horizon is also the fastest spacecraft ever built, racing at one million miles per day. All these remarkable achievements were made possible thanks to plutonium-238 and the technology developed to harness its heat.
It's Saturday, so time for some fun physics. This non-trivial question is often asked in international physics contests and requires a bit of out of the box thinking.
Despite lacking a rigid skeleton, octopuses have a remarkable coordinated locomotion. Using high-speed cameras, a group at the Hebrew University of Jerusalem found the octopus achieves this by precisely and independently moving one or more of its eight legs to crawl its body, even when its facing a different direction. Moreover, there is no discernible rhythm or pattern to this undulating leg movement, making the octopus unique in this respect. It's controlled chaos, and only the octopus itself completely knows how it pulls all this off.
Electronic cigarettes have soared in use among high school and middle school kids, tripling relative in 2014, while cigarettes have reached an all time low. The report was issued by the Centers for Disease Control and Prevention, which found 4.6 million middle and high school students were current users of any tobacco product, which includes e-cigs despite the fact that it doesn't burn or contain any tobacco - just the nicotine.
Upon acquiring virtual technology company Oculus, Facebook CEO Mark Zuckerberg predicted that virtual reality technology would one day permeate areas of life further than just the world of gaming, and we would ‘someday [use virtual reality] to enjoy a courtside seat at a basketball game, study in a classroom, consult with a doctor face-to-face or shop in a virtual store’. It’s true - the creation of immersive, virtual environments does indeed have masses of potential for industries which beforehand, were seemingly incongruous with such technology. Social psychology, the study of human experience and behaviour, is one of them.
These two dim dots are none other than Pluto, the dwarf plant, and Charon, its largest moon. Though it might not look like much, this is the first ever colored photograph of the two cosmic bodies ever taken. We have NASA’s New Horizons spacecraft to thank for this, which used its Ralph color imager to make the shot from 71 million miles away.
In most cultures, men are typically regarded as handy and it’s usually up to them to do the handy work – it’s quite a stereotype actually, but I think it’s among the few that really stick; but a new study reveals that women may actually be much more well suited for that job. Female chips […]
Today, SpaceX's Falcon 9 rocket blasted off Florida's Cape Canaveral Air Force Station at 4:10 p.m. EDT (2010 GMT) carrying the Dragon capsule to orbit, on slate for its rendezvous with the International Space Station where it's tasked with a resupply mission. Instead of dropping in the ocean like the gazillion other rockets before it, the first stage of Falcon was programmed to make a controlled landing on a "autonomous spaceport drone ship." The rocket did land on the spaceport, which is amazing in itself, but unfortunately it flipped over post landing and was damaged beyond repair. So, just almost!
Some 900 Dutch citizens have banded together and filled a lawsuit against the Dutch government over human rights, citing the latter's lack of decisive action against climate change. This is the first such case in Europe where a group of citizens holds its government responsible for ineffective climate policy, and also the first to be based on human rights law.
This is the first map in a series of maps that will be stitched together to form a grand picture of how dark matter is distributed across the Universe. Dark matter is basically invisible, which is why it's called dark in the first place, so scientists rely on indirect observations like the gravitational effects it poses to locate and map it. What we're seeing now is only 3% of the area of sky that the Dark Energy Survey (DES) will document over its slated five-year-long mission.
Strange weather in the East Coast and California's worst drought in history have been linked to a peculiar warm mass of water out in the Pacific Ocean. A new study published in the Geophysical Research Letters explain its origins and how its warm waters also warmed surface temperatures out in the coast, and displaced marine life, a major concern at the moment. Worth noting that research thus far suggests that 'warm blob', as it's been dubbed, has been primarily attributed to natural variability, and not global warming.
The threat of punishment and humans' seemingly innate tendency to copy other behaviors form the basis of a psychological model that explains how traditions or entrenched ideals are formed and maintained in society.
It's common sense - in order to brush your teeth, you need water, a toothbrush, and toothpaste. Well, a company from Japan wants to change all that: they've developed a nanotechnology toothbrush that basically eliminates the need for toothpaste.
With the development of the internet and technology, data availability is rarely a problem - it's what you do with the data that actually matters. As a matter of fact, analyzing huge data sets and looking for patterns is a big part of what programmers do today. In what promises to be a huge change, computer scientists have developed so-called probabilistic programming languages, which let researchers mix and match different machine-learning techniques.
NASA's Dawn spacecraft already has an impressive resume - it's traveled to the strange area between Mars and Jupiter and managed to start orbiting the dwarf planet Ceres, even though Ceres measures only 950 kilometers (590 miles) in diameter and has a very small gravitational field. But it's not stopping just yet - after previously revealing a number of black and white pictures, Dawn has now provided a color photograph, but here's the thing - it poses more questions than it answers.
A "massive methane hotspot" sounds pretty bad... and bad it is - much worse than previously thought. In 2014, NASA reported that the methane hotspot is responsible for producing the largest concentration of the greenhouse gas methane seen over the United States – more than triple the standard ground-based estimate. But the methane, a potent greenhouse gas, might have even more drastic consequences on the climate of our planet.
You’re standing in a crowded space when suddenly the fire alarm goes off. Do you a) immediately proceed to the exit, or b) wait for other people and head out as part of a group? The answer probably depends on who you’re with at the time, and according to a paper published recently in the journal PLOS ONE, the distinction may be crucial during emergency evacuations.
Researchers have long known that Mars has water in the form of ice, but now, after years and years of research, we might finally have the decisive clue that our planetary neighbor has liquid water on its surface. The key find was perchlorate - a substance that significantly lowers the freezing point, so that water doesn't freeze into ice, but remains liquid and briny.
There's so much you can do with a smartphone today - much more than just browsing the web or social media. When you can combine them in a network, however, the possibilities might be endless. For instance, researchers at Caltech and the United States Geological Survey (USGS) are working on an earthquake early warning system based on the collective data fed in by thousands of smartphones. Only a couple of countries in the world give vulnerable cities an early warning - often just enough time to hit cover and save your life - but smartphones are virtually ubiquitous all over the world, even in poor countries which lack basic infrastructure like roads or flushing toilets.
Astronomers have known for quite a while that Mars has distinct polar ice caps, but the Red Planet might also have belts of glaciers at its central latitudes in both the southern and northern hemispheres. These huge glaciers are covered by a thick layer of dust which masks them and makes them seem like they are actually part of the surface of the ground.
European males are on average 11 centimeters taller now than they were in the 1870s, which is quite a lot by all means. Everybody makes fun of Napoleon for being short, but as a matter of fact he was actually standing above average height! Thank better nutrition and medicine for that. Even so, what in the world are the Dutch eating that makes them this tall? The average Dutchman now stands over six feet tall, and while the rest of the world seems to have stopped, they're still riding a growing trendline. The answer by actually be evolutionary - the tall Dutchmen have more babies.
The US Department of Energy (DoE) has sealed a deal with Intel worth $200 million to build what's supposed to be the world's most powerful computer in 2018: the Aurora. The behemoth will be based on a next-generation Cray supercomputer, code-named “Shasta,” and will use Intel’s HPC scalable system framework. Aurora will likely reach a peak performance of 180 petaflop/s, or 180 quadrillion floating point operations per second (completed algorithm action, not just instruction). For comparison, a 2.5 GHz processor has a theoretical performance of 10 billion FLOPS.
Some kids seem to enjoy school activities more than others, but while efforts seem to be concentrated on improving teaching, a new research suggests that genes play a major role as well - sometimes they're more important than the environment, as far as motivation and doing well in school are concerned. The findings were reported by a team led Yulia Kovas of Goldsmiths, University of London that aggregated a swath of studies which included 13,000 twins aged nine to 16 from six countries, including the UK, Canada, Japan, Germany, Russia and the US.
Just like our own planet, the sun goes through seasonal changes in its activity, waxing and waning over the course of nearly two years driven by changes in newly discovered bands of strong magnetic fields. This variability helps shape the sun's long-term 11 year cycle, yet again part of a longer cycle that lasts 22 days. Largely unpredictable, the sun constantly spews highly charged particles known as coronal mass ejections which can severely affect power grids, satellites and even airplane passengers. During its seasonal peaks, however, the sun is much more prone to solar storms, so understanding how this cyclic variability happens is key to averting a potential disaster.
Dealing with invasive species is one of the challenges that accompanies globalization and in many areas of the world, it's becoming harder and harder to tackle this issue. In the Colorado lake, 3,000 Koi fish (Japanese carp) are now swarming the water, wiping out native species and dramatically altering the environment.
When tyrannosaurs ruled the world, no one was safe from them - not even other tyrannosaurs. The skull of an unfortunate adolescent tyrannosaur shows signs of brutal fight; the individual was defeated and then eaten by members of its own species, new research shows.
