Using a novel deep learning algorithm, a team at UC Berkeley demonstrated a robot that learns on the fly and performs various tasks that weren’t pre-programmed. It starts off shy and clumsy, but eventually gets the ahead of it. For instance, after it stomped a bit around its environment, when given a new task, but with no further instructions, the robot learned by itself to assemble LEGO bricks or twist caps onto pill bottles.
Two years ago, following the discovery of the Higgs boson – heralded as one of the greatest scientific achievements of this century – the Large Hadron Collider at CERN was shut down for much needed maintenance and upgrades. A few days ago, the massive particle accelerator was shifted into gear and powered up. The first test run wasn’t only successful, it set a new record by producing collision energies of around 13 trillion electron-volts. The highest speed that was previously achieved was of only 6.5 TeV. More tests will be made throughout the remainder of this month and June.
It’s no secret that TV food commercials stimulate pleasure and reward centers in the brain, after all advertisers wouldn’t pay big money for them to air if they didn’t entice people to order more. In fact, food advertising has increased dramatically over the past 30 years. Teenagers are exposed on average to 13 food commercials on any given day. At the same time, childhood and adolescent obesity in the US has been on the rise fast and worrisome, so we can’t help but notice the connection. Now, researchers at Dartmouth found overweight teens are disproportionately affected by TV food commercials, as key brain regions that control pleasure, taste and – most surprisingly – the mouth are all much more stimulated than those teens with less body fat. The findings are important since they suggest overweight teens exposed to this kind of environment will experience further difficulties when they try to lose weight. A further insight is that dietary plans should also target subsequent thinking concerning eating food, not just the temptation.
Astronomers have captured a glimpse in the life of a massive star, a brief transitory stage in its evolution that might reveal the secrets of a unique class of stars. It’s called Nasty1, a name derived from its catalogue name, NaSt1; but the name is quite fitting, considering that the star itself has a pretty erratic behavior. Nasty1 is part of
A stunning round solar halo caused a social media frenzy – people were out in the streets, taking photos, sharing them, while scientists were also excited to see such a rare phenomenon. But what are solar halos, and why did this one appear in Mexico?
In 1921, archaeologists found the remains of a Bronze Age priestess, dubbed the Egtved Girl. Now, a new study reveals that the priestess, who was found in Denmark, likely traveled hundreds of kilometers and was born somewhere in Germany. The Egtved Girl was, according to all clues, an extraordinary person. She only lived to be 16-18. She was slim, 160 cm tall
In what’s perhaps one of the most amazing marine science study, a team of researchers scoured the world’s oceans fishing for microbes, viruses and other tiny life during a three and a half year trip aboard a schooner. The trip was long and arduous for sure, but ultimately it paid out – big time! The team collected 35,000 samples at 210 stations over the voyage, and found 35,000 species of bacteria, 5,000 new viruses and 150,000 single-celled plants and creatures. Most of these are new to science. Only a small fraction of the newly discovered and known species alike had been genetically sequenced, but results so far show just how interconnected and symbiotic marine life is. It also means it’s also vulnerable in the face of environmental changes, particularly climate change.
Just a few days ago were telling you about a huge, 10,000 year old ice shelf that is set to collapse in less than 10 years and now… the same thing is happening again, a bit more to the south.
When citizens stop complying with the laws, it’s generally a bad thing – laws are there for a reason, and not respecting the laws carries negative consequences – for the people involved, and for social order. But what if, consciously or not, citizens are actually disobeying the laws in order to enact positive changes? A new MIT study found that sometimes, that’s exactly the case.
A massive study conducted by the Massachusetts Institute of Technology concluded that solar has the most chances to meet our planet’s long term energy demands, while also reducing greenhouse emissions. However, governments should be more supportive of the industry’s development.
It’s striking how a company like Research in Motion (RIM) went under the radar so fast, considering it used to completely dominate the smartphone market only a couple of years ago. After all, Blackberry almost used to be synonymous with a smartphone, although competition wasn’t so fierce back then. Then the iPhone came out in 2007. Spoosh! In just one
According to the Chinese Central Television, China wants to land rover on the far side of the moon, also know as the dark side of the moon, by 2020. This would make it the first nation to land a spacecraft of any sort there. First, the rover will orbit the moon piggy-bagged by the Chang’e 4 spacecraft then later deployed to a launch site. The rover will carry out some scientific missions, but the main goal really is to test China’s space launching capabilities, but also as a show of force. Flex those muscles, sort to speak. Some analysts, however, speak out that there might be more to it, namely a bid for the moon’s resources.
Four cancer charities operated by the same family under a scamming scheme were sued by the Federal Trade Commission and attorneys general in all 50 states and the District of Columbia. The group allegedly scammed consumers out of more than $187 million, who in good faith wanted to contribute to a good cause. In some cases, the charities asked people for money that would eventually help children with cancer, one the most vulnerable groups. Instead, only 3% of the money the group raised actually went to charitable causes. The rest was pocketed.
Biologists have long suspected that cephalopods like the squid and cuttlefish have specialized proteins embedded in their skin, very similar to those found in the eye, which they can use to perceive light, and maybe even colour. Where previously attempts failed, a team at University of California at Santa Barbara now offers conclusive evidence that octopuses can ‘see’ with their skin. Namely, they can definitely perceive light characteristics like wavelengths, brightness and such, but not edges or contrast. So, you might as well add full body vision to the list of awesome octopus features: master of disguise, elegance in chaos, survival in sub-freezing Antarctic temperatures or special untangling switches. But hey, who’s counting anymore. As much as octopuses are weird, they’re just as fascinating!
There are two types of galaxies: ‘alive’ and ‘dead’ ones. Those galaxies that are still alive are called so because they still produce stars inside, while the dead ones are stripped and devoid of their stellar nurseries. In a case of forensic astronomy of the utmost importance, a team at the University of Cambridge and the Royal Observatory Edinburgh has revealed the leading cause of death for most deceased galaxies of average size: death by strangulation. What remains now is to identify the killer, the researchers say.
A freak accident from his childhood in Iceland caused Gudmundur Olafsson’s right ankle to collapse. After 28 years of living in pain and more than 50 surgical operations he decided to amputate his lower leg entirely. For years, he wore the Proprio Foot – a prosthetic motorized ankle developed by an Icelandic company called Ossur which can automatically adjust the angle of the foot using its built-in sensors. Now, Olafsson prosthesis got a major upgrade: his new Proprio is controlled subconsciously by electrical signals sent from his brain to special sensors directly embedded in his muscles, all via the nerves in the muscle itself. Then a decoded signal is sent to a control unit which directs all the fine moving parts that make up his new, robotic leg. All his intentions are translated seamlessly by the sensors and Olafsson, now 48, can walk almost entirely like a normal person. “The first time, to be honest, I started to cry,” said Olafsson.
A dedication ceremony was held today at the Advanced Laser Gravitational Wave Observatories (Advanced LIGO), a lab tasked with detecting gravitational waves. The two LIGO observatories located in the US’ northwest – one at Hanford, the other at the LIGO observatory in Livingston, La – have received significant upgrades meant to increase their sensitivity, part of a huge international endeavor which took eight years and $200 million to complete. The discovery of gravitational waves is heralded as a milestone breakthrough in physics and astronomy, one that might teach us a lot about the Universe. This includes supernovae and colliding black holes, that generate the waves.
The loud noise that usually airline passengers have to deal with in mid-flight can significantly alter how food tastes. According to researchers at Cornell University sweet flavors are inhibited, while savory flavors are enhanced. This might serve to explain why, for instance, tomato juice is such a popular beverage served on flights. German airline, Lufthansa, reports its passengers consumed 1.8 million liters of tomato juice in a single year or just as much as beer. Quite a lot, considering few people actually buy tomato juice back on land.
Social media was ecstatic – just look at this video of an orangutan bottle-feeding a tiger cub. Tens of millions of people tuned in to watch this “cuteness overload”… but the truth behind this is not cute at all. It’s actually quite saddening. We’ll discuss why, after the video.
Don’t make that face. It’s not like you didn’t see it coming, after all with each technological step forward porn has always shared the ride. Among the oldest surviving examples of erotic depictions are Paleolithic cave paintings and carvings. Prints became very popular in Europe from the middle of the fifteenth century, and because of their compact nature, were very suitable for erotic depictions that did not need to be permanently on display. An earthier eroticism is seen in a printing plate of 1475-1500 for an Allegory of Copulation where a young couple are having sex, with the woman’s legs high in the air, at one end of a bench, while at the other end a huge penis, with legs and wings and a bell tied around the bottom of the glans, is climbing onto the bench. The oldest surviving permanent photograph of the image formed in a camera was created by Joseph Nicéphore Niépce in 1826, porn likely soon followed there after. Imagine what happened once film came along. Nevermind the internet. Though the Oculus Rift is still in beta, and only a handful of developers own one, virtual reality is certain to change how people enjoy porn.
