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 […]
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.
An innovative concept might allow engineers to send probes on Mars in previously inaccessible locations. The project, called MARSDROP, would send two landers to the Red Planet, where they would detach from the shuttle and glide down to the planetary surface.
A new analysis conducted by Yale researchers revealed that the first snakes may have actually evolved on land, not in water. These proto-snakes were likely night hunters that might have had hind legs and even toes. “We generated the first comprehensive reconstruction of what the ancestral snake was like,” said Allison Hsiang, lead author the […]
Giant pandas love to feast on bamboo - it's their favorite food, and they easily make quick work of it, using their powerful jaws to peel the plant's tough bark and get to its tender core. But even though the pandas love it, their stomachs don't - a new study has revealed that the panda's stomach is not adapted to a completely herbivorous diet, and still craves for an omnivorous meal, like other bears.
A shocking conclusion came from an International Monetary Fund report: they found that fossil fuels will be subsidized by a whopping $5.3 trillion dollars, way more than total health spendings of the entire world combined.
Scientists have managed how to create morphine using a kit like the ones used to make beer at home. They used genetically modified yeast to perform the complicated process of turning sugar into morphine, and while they believe this can have huge medical significance, they also express concerns about "homebrewed" drugs.
At his commencement address at Rutgers University, Bill Nye - famous for popularizing science as the Science Guy - said that climate change is the most serious crisis mankind has ever faced, liking the psychological pressure to that experienced by our parents and grandparents during World War II. He then called on the students to rise to the challenge and question those who deny the reality the planet is currently facing out of ignorance or malevolence alike.
Researchers have long theorized that the superior temporal sulcus (STS) is involved in processing speech rhythms, but it's only recently that this has been confirmed by a team at Duke University. Their findings show that the STS is sensitive to the timing of speech, a crucial element of spoken language. This could help further our understanding of how some speech-impairing conditions arise in the brain, or aid tutors design next-generation, computer assisted foreign language courses.
With bee numbers dropping dramatically in the last years, it's time to take some drastic measures, and a White House task force including participation from more than a dozen federal agencies has concluded that limiting pesticide use may be the last resort we have to maintain bee numbers.
Our bones are much lighter and weaker than those of our Paleolithic ancestors (11,000 to 33,000 years ago), but it's not our spoiled modern day lifestyle that's to blame. Instead, a new study which closely compared homo sapiens bones, both ancient and modern, found that the most significant changes occurred once the paradigm shift from hunter-gatherer to agriculture took place, some 10,000 years ago. Humans started forming permanent settlements, worked the land and tended to flocks. Consequently, the lifestyle became more sedentary.
Geologists are expecting increased activity on the Kilauea volcano, warning that another eruption is likely possible. It seems that lava continues to build up, as manifested through a swarm of minor earthquakes.
California's record drought has completely dried off large swaths of rivers, including the San Joaquin River, which means that juvenile salmon can't actually reach the sea. In a desperate effort to save an entire generation of hatchlings, authorities are transporting them by truck, on the highway.
Astronauts onboard the ISS may soon get a new "toy" - a space laser cannon to blast off space debris that might threaten the space station. Even a tiny scratch or dent could cause massive problems, and with us putting more and more stuff in space, the risk of damage constantly increases too.
A Spanish startup called Vortex Bladeless has been receiving a lot hype recently once it unveiled a prototype for a bladeless wind turbine. Like conventional pin-wheel turbines, their turbine also works by harnessing the kinetic energy of the wind. However, instead of moving blades which in turn rotate a shaft connected to a generator, the "asparagus" turbine uses a magnets to transform oscillating movements into electricity. It's a radical idea, one that might forever change the scenery most of you have already become used to - huge parks of windmills, which personally I'm rather fond of. So far, the engineers behind the project have been rather secretive and the only things we know about the Vortex Mini (the first commercial turbine of this kind set to come out next year) is what has been disclosed by the company. They're boasting an impressive performance - to the point that it might be feasible to forego pin-wheel turbines altogether in favor of the Vortex - but until we seen some independent assessments I believe skepticism is warranted.
Astronauts onboard the International Space Station were given a treat - they witnessed one of the most spectacular natural phenomenon on Earth, from space. From onboard the station, Terry Virts also filmed it and took some pictures, so we can all enjoy.
It's raining... spiders. Countless baby spiders are falling from the ski in the Australian city Goulburn, South Australia, covering the entire landscape in spider webs.
A turtle named Akut-3 was fitted with a new, custom made 3-D printed jaw by doctors at the Research, Rescue and Rehabilitation centre at Pamukkale University in Denizli, Turkey. The reptile was found badly injured at sea and brought to the center for rehabilitation. At first, the doctors healed the turtle's wounds and hand fed her, but they knew they had to turn to something more drastic if the animal was to ever fend for herself in the wild again. They turned to a company in Turkey known for custom made prostheses, gave them a detailed CT scan of the turtle's skull, then received a new beak made out of medical-grade titanium. The prosthesis perfectly fit Akut-3, who is aptly named like a cyborg.
A mini-drone that fits in the palm of your hand could give the military an upper hand on the battlefield by providing key intelligence readings. Hundreds of these small, plastic drones could be dropped off a flight and left to scatter across the battlezone. Though they don't have any engines, these "Cicada" drones are equipped with sensors that help adjust the gliding pattern, directing the drone towards a dropzone with an accuracy within a couple of feet. These are hard to spot since they easily disguise as a bird from afar and once behind the lines can use their sensors and microphones to spy on enemy positions. These can also prove very useful for civilian missions, most notably for gathering meteorological data.
According to a new study, just like tree rings carry with them hints about previous dry or rainy years, bones in fish carry with them a specific signature which records the chemical composition of the waters they used to live in. Most vertebrates, especially fish, have what is called an ‘otolith’ – a specific bony structure […]
Fruit flies experience fear, one of the primary emotions, according to a new research that suggests there's much more to flies scattering about in the face of a swatter than a mere robotic reflex. But do the flies feel other emotions too? That's an extremely difficult question to answer, since the researchers themselves aren't even sure what they've been observing is genuine fear. It does, however, bear all the characteristics of fear. The findings are important since the show that other "lesser beings" that have a primitive nervous system like other insects or spiders might also experience fear, and possibly other emotions as well like happiness or sadness. Who knows, maybe love too?
NASA is offering up to $2.25 million to anyone that can successfully design a habitat that can be 3D printed on Mars. The announcement is part of a broader attempt by NASA to outsource ideas and projects.
A NASA study has found that a huge ice shelf is set to collapse in a few years. The ice shelf, which has existed for over 12,000 years, is estimated to be over 200 meters thick.
With all its cons and pros, at this time, nuclear power remains our best shot at decarbonizing the planet and ridding the world of its dependence of fossil fuel. During the 60s and 70s, many of the world's governments, including France, the US or the USSR embarked on ambitious projects to electrify their nations using nuclear power. Accidents like those at Three Mile Island (1979), Chernobyl (1986) or Fukushima (2011) served to halt this rapid pace of deployment and even shift policy back to massive fossil fuel deployment. Anti-nuclear power public sentiment did little to help, of course. Considering that the combined power of solar, wind and hydropower can't yet rid us of pesky oil and gas, wouldn't it be better if we embraced nuclear nevertheless, with all its shortcoming (many of which have been addressed by modern technology)? Two researchers wondered if the world was to hypothetically shift in high nuclear gear, how long would it take to completely shelve fossil. Their analysis showed if we built nuclear power plants at the rate Sweden had between 1960-1990, this target would be reached within 25 years.
We use the word "humane" to describe kind behavior and sympathy towards others, but the term might falsely lend some to believe that this is an exclusive human quality. Far from it. Rats too are kind, sympathetic and as "humane" as any human. For instance, when their peers are in danger of drowning, rats will come to their aid to save them. Even when a tasty treat, like chocolate, is offered instead the rat will most often than not choose to help his dying friend. To hell with chocolate!
Sexual equality might be the mark of a civilized society, but it's definitely not a new thing. In fact, there's much we can learn from our so-called primitive forefathers and foremothers, who likely lived in closely bonded communities where sexes shared equal influence and contributions, according to a study published by a team at University College London. The researchers investigated modern hunter-gatherer communities, one in Congo and the other in the Philippines, then constructed a computer model. Their model showed when only one sex had influence over how the group migrated for food or who lived with whom, the close community crumbled and did not reflect what was actually happening in reality. The researchers believe sexual segregation and male dominance in most cultures appeared following the advent of agriculture, as more resources became available.
Something is killing off the bees; it's likely us, and we'll all have to pay the price. In fact, in many areas of the world, we already are.
Though it's a deep ocean fish, the slender opah is actually fully warm blooded - the first of its kind discovered so far. This remarkable insight was made by accident after researchers at the National Oceanic and Atmospheric Administration dissected the fish and noticed its blue and red blood vessels were located inside the gills, rather than in the fish's swimming muscles. Tuna or sharks, which both have the same vessels but not arranged in the same way, cool their blood once it reaches the gills for oxygen reloading. The opah's vessels are interwoven inside the gill like a net, which means the the veins that carry warm blood away from the hot muscles are interwoven with the arteries that carry cold blood in from the gills. This makes all the difference. Running so close to each other, the warm blood from the heart heats the cold blood from the gills. This way the Opah is 5 degrees Celsius warmer than its surroundings waters!
Researchers at UC Santa Barbara made a simple neural circuit comprised of 100 artificial synapses, which they used to classify three letters by their images, despite font changes and noise introduced into the image. The researchers claim the rudimentary, yet effective circuit processes the text much in the same way as the human brain does. In other words, like you're currently interpreting the text in this article. Even if you change the font, printscreen this article and splash it with an airbrush in MS Paint, you'll still be able to read at least portions of it, because the human brain is so great at scaling patterns and abstracting symbols. This kind of research will hopefully usher in a new age of more refined, energy efficient computing.
Cuba, famous for its rum and cigars, might be one of the unlikeliest places people think of when cutting-edge biotech research is concerned. Despite economic sanctions and embargoes set forth by the US and partners, the country's medical research institutes boasts some impressive results, particularly in immunization. One prime example is a lung cancer vaccine developed at Cuba’s Center for Molecular Immunology which increases life expectancy by up to six months. Now, the Roswell Park Cancer has signed an agreement with the Cuban medical center to finally bring the vaccine to the US for clinical trials.
Printing your own mechanical parts or toys is really easy, not to mention fun, using a 3-D printer. But things get a bit trickier when you want to print the kind of parts that go into a car or airplane. Metal is a lot more complex to work with inside a 3D printer than polymers like ABS - the kind of film roles that get melted layer by layer to form a part of your liking once it cools down. Engineers at General Electric just demonstrated, however, that in practice it's not that complicated to print parts out of metal alloys as it sounds. The team used additive technology to build a fully functional jet engine, then test powered it to 33,000 RPMs. The company is already using 3-D printed fuel nozzles in its next-generation aircraft engines, slated to role out in 2016.
There's a growing body of evidence suggesting Vitamin D plays an important role in regulating serotonin. This means it could cause (deficiency) or treat Autism Spectrum Disorder (ASD) symptoms (supplement). For instance, one study prescribed Vitamin D3 to autistic children in an open trial and had a 80% success rate - that is, the children became less hyperactive, irritable, and engaged far less in stereotypical behavior. The children were also more responsive and compliant to their families.
Nine years and 3 billion miles later, New Horizon finally got close enough to Pluto to spot it along with all its faint moons. The probe photographed Pluto's five "underworld" satellites, Charon, Nix, Hydra, Kerberos, and Styx, Long Range Reconnaissance Imager with 10 seconds exposure. Light is a bit faint once you're so far away from the sun that there aren't any planets left to explore. Not if you count Pluto as one, though, since New Horizon will flyby past it in July. Some still stick to calling Pluto a planet, though officially it's been demoted to dwarf planet status.
At the Canadian Institute of Mining's annual convention, NASA scientists said exploration and prospecting of celestial bodies like the moon or asteroids is decades away, but even so this shouldn't stop regulations from being well established in advance. At the event, concerns were raised that ownership and management of resources in outer space are still far from being resolved.
Most evolutionary biologists seem to agree, based on fossil record, that the birds of today are direct descendants of dinosaurs, and that the first bird ancestors evolved some 150 million years ago. Though valuable, fossil records alone are not enough to recreate the DNA migration and tweaking that occurred to give rise to the avian family. What if you went from your original product (the bird) and genetically traced your steps backwards millions of years into the past? This is where a novel research might come in made by a collective from Harvard, Yale and several other universities. The scientists used the knowledge their garnered in eight years of research about how bird beaks form in the embryo stage to shut down key protein sequencing to basically breed birds with primitive, dinosaur-like snouts.
In 1976, Carl Sagan went on the Tonight Show with Johnny Carson along with a strange contraption, that looked like a tinfoil square. In all likelihood it was probably tin foil, since it was only a model for what Sagan termed as a solar sail - a simple, but effective spacecraft that harnesses the solar winds to generate power, much like a sail uses the wind to move a ship here on Earth. On May 20th, a tiny satellite the size of a loaf of bread will be blasted into Earth's orbit from an Atlas V rocket that will test Sagan's design.
Climate models and environmental monitoring missions are ever more reliant on autonomous underwater vehicles (AUVs) to scour the ocean depths and bring back valuable data like temperature, salinity, carbon levels and so on. Researchers at MIT have now upgraded the way AUVs perform their missions by adding an extra dimension to their autonomy. They demonstrate how a pack of AUVs, directed by a "captain" drone, is able to navigate obstacles and retrieve data with minimal intervention. This dramatically enhances performance and might revolutionize the way scientists study the oceans.
The MESSENGER spacecraft spent four years orbiting Mercury, gathering valuable information and sending it back to Earth. But even in its final moments, as it crashed towards the surface of the planet, the spacecraft still did its job - it reported that Mercury has a magnetic field, likely millions of years old.
It seems like the people of Nepal just can't catch a break - another large, 7.4 earthquake has struck, sending the people from the capital of Kathmandu running on the streets scared.
Researchers from the University of Pennsylvania have discovered a new species of dinosaur, closely related to the famous velociraptor. This new species, Saurornitholestes sullivani was a bit bulkier, probably had a better sense of smell, an researchers believe it was an even better predator than its cousin.
The proportions of fake animals, the subject of long and heated debates in the scientific community, have been revealed by researchers at University of Manchester. The team used X-rays and CT scans to look inside 800 animal mummies, some of which were more than 3,000 years old. Only a third actually contained an animal skeleton. Another third contained only fractions of a complete skeleton, sometimes just a single bone. The rest were all mud casts, filled with twigs or other organic material, made to look like a real animal was inside. So, is this an exposed elaborate scam routine performed over the millenniums? Not quite - the researchers believe something more innocent is at play.
Using its Mast Camera, the Curiosity Rover has snapped stunning images of a blue sunset on the Red Planet. The blue-tinted images show the Sun dipping into the horizon as blue streaks shroud the sky across the evening light.
