University of New South Wales devised a two-qubit system inside a silicon chip and ran a computer code adapted to the quantum world. Their code passed the notoriously intransigent 'Bell test', making it the strongest evidence yet that quantum computers can be instructed to handle operations.
The bat is the only flying mammal and among the heaviest in the world. To top it over, it can land upside down a perplexing acrobatic feat which has left scientists scratching their heads for many years. After carefully and systematically studying bat upside landings in slow motion, a group of researchers thinks it has cracked the puzzle: bats employ a nifty trick where one wing stays flapping while the other is moved close to the body. This asymmetry corrects the moment of inertia and center of mass so the bats always land safely upside down.
Or when your experiment's results are 'almost' there.
Today is World Prematurity Day - a global effort to raise awareness about the deaths and disabilities due to premature births. Each year around the world, 15 million babies are delivered ahead of term and 1 million children die before their fifth birthday from related complications. Some who make it past this dangerous threshold might get to live with serious disabilities.
It's widely agreed that modern Europeans trace their roots from three ancient tribes, or three important migration events, if you will. But after researchers sequenced the genomes of two hunter gatherers who lived roughly 13,000 years ago, there's evidence that suggests a fourth tribe lent our genes.
Self-preservation and reproduction are the most powerful instincts, and life forms on Earth have devised all sorts of gimmicks and tactics to become successful (pass on those genes). Just look at the male ruff sneak tactics to grab girls. There are three distinct approaches: the cocky aggressive, the sneaky 'satellite, and the cross-dresser. You might think this isn't necessarily peculiar in itself. After all, human males employ similar approaches to seek women's attention. The peacock, the friend-zone dude, the jock, the joker etc. What's odd about ruff males is that this behavior is coded inside their genes - from the way they act, to how their plumage looks like. And they're all, ultimately, males of the same species.
The free market once again showed its limitations, or rather its power of abuse, after a Canadian pharmaceutical company priced gauged a drug critical for a rare form of epilepsy that affects infants. Questcor Pharmaceuticals hiked the price from $35.66 to $801.19 per vial. "Luckily", Toronto’s Hospital for Sick Children and the Ontario Drug Benefit (ODB) program negotiated the price down to $680 per vial, bringing the total cost of treatment to $14,280.
Some 360 million years ago, the oceans were teeming with big fish, some as big as a school bus. Then something terrible happened, the causes of which still escape scientists today: the Hangenberg Event. This was the last peak in a streak of mass extinctions known as the Late Devonian extinction which exterminated 97% of all marine vertebrate species. In the aftermath, it paid to be small a new study suggests. The researchers at University of Pennsylvania found that small fish dominated the ecological niches for nearly 40 million years. This tremendous rebound time is relevant today when overfishing is threatening countless large fish species. Once these disappear, it might be a very long time before we get tuna-sized fish back on our plates.
In a leap of innovation, Samsung unveiled the largest storage unit ever: a 15.36TB flash drive which uses 256GB NAND flash as the basis for the storage. The hard drive is 60% bigger than its closest competitor and all that storage is packed inside a tiny 2.5-inch SSD case. And yes, I prefer to still call it a hard drive even though there aren't any motors, pivots or arms. Deal with it.
At the U.N. summit on climate change held in Paris soon, world leaders will join in an attempt to curb their emissions in order to avoid warming by more than 2 degrees Celsius past the industrial age. We're already 0.9 degrees warmer and by the looks of the pledges filed by member states ahead of the talks, a more realistic target seems like 3 degrees. In other words, the framework - which will not be legally binding - will only have moderate effects, when more ambitious action is required. One big part of the problem is fossil fuel subsidies, which last year amounted to $452 bn. in total for all G20 member states. Oppositely, renewable energy - a field which actually deserves to be subsidizes since its new tech and isn't mature yet - was subsidized by only $121 bn. or four times less.
In the wake of big festivals like Coachella or Glastonbury, you'll find trash and the ravages of partying littered across the whole site. Oddly enough, you'll also find loads of abandoned, but useful gear like phone chargers, couches and, most frequently, tents. A creative Dutch designer now has an idea on how to repurpuse the latter: turn them into suits that double as sleeping bags for the homeless.
YouTuber Ziggy Zee prides himself with building the most powerful mobile electromagnetic railgun ever made by a non-gov. Just look at that thing. I'm scared at it is, but wait until you hear what it can do.
Bees play a critical role in maintaining natural plant communities and ensuring production of seeds in most flowering plants. But humans too have a close relationship with bees, which spans over a history close to 9,000 years, a study found which analyzed ancient pottery. That's a lot earlier than previous recounted evidence. Right now, however, honeybees are dying at an astonishing rate. The fact that bees have been feeding and nurturing humans for so long should only make us more humble, but also more steadfast in finding a solution.
One day in 1885, the twenty-three-year old apprentice machinist Henry Ford came into contact for the first time in his life with the gas-powered internal combustion engine. It was love at first sight. Instantly, a wave of excitement overcame him for he envisioned even at that tender age and during those uncertain times that horseless carriages will forever revolutionize transportation. This was to be his life's work.
What is this sorcery? Why, magnets of course, and two Norwegian students have found a way to make magnetism more entertaining than ever.
While Americans are in favor of renewable energy and electric cars, when it comes to paying more for gasoline support dwindles. Are the voters hypocritical? Not necessarily. A new study suggests that voters would be in favor of a gas tax, if they'd know the cash would flow directly into measures that address energy efficiency, fix roads and bridges or gets refunded to taxpayers equally. In other words, if people know what they're paying for, they'll be more willing to pitch in. Who would've thought, right?
Microsoft released an app that can guess emotions based on an uploaded photo.
Not every groundbreaking idea is complicated to understand. Ryan Chester, a high school senior from Ohio, seems to think so too. Using simple props and graphics, Chester produced a fantastic short video explaining one of the most important theories in physics - the Theory of Special Relativity proposed by Albert Einstein one hundred years ago. If the name doesn't say too much, maybe E = mc2 will.
Last week, New York District Attorney Eric Schneiderman issued a subpoena to Exxon Mobil ordering the company to provide financial information, as well as internal communications including emails, and other materials as far back as 1977. Schneiderman is investigating Exxon over suspicion of willfully failing to mention to its investors the risks climate change might pose to the company's business. If this is true, then Exxon effectively violated its fiduciary duties and can be held liable. Moreover, the investigation might surface certain information that might uncover racketeering and securities frauds, since it's well known, although harder to prove per se, that Exxon has been involved in manipulating public opinion on the matter, risking public health in the process - a situation akin to big tobacco which actively sought to convince the public that smoking isn't bad for health.
There is only one clear set of official criteria by which we class or not a cosmic body as a planet. These criteria introduced in 2006 by the International Astronomical Union saw Pluto demoted to the status of dwarf planet. Oddly enough, though, these rules were made for classing planets only in our solar system, meaning the 5,000 exoplanets (what should be planets outside our solar system) identified so far are now in a "definitional limbo," according to planetary astronomer Jean-Luc Margot at UCLA. Luckily, Margot has come up with a solution which seems to work marvelously.
Nobel Prize-winning Richard Feynman was one of the greatest physicists of the past century and a man of many talents.
We all have a friend that enjoys inappropriate jokes or slapstick humour more than any sensible person ought to. University College London researchers now claim that a twisted sense of humour might be an indicator of dementia setting in, particularly if the person in question used to have a different sense of humour.
According to NOAA's Coral Reef Ecosystem Division about 30 percent of the world's coral population has perished due to average ocean temperatures, El Nino's effects and acidification. Even if we halt all man-made CO2 emissions now (virtually impossible), the cascading effects of ocean acidification can not be halted once they've been set in motion. As a result, coral all over the world will bleach more frequently and intensely. Desperate times indeed, but a group of scientists are trying their best. They identified strong coral specimens and are currently stressing them further so they become more resiliant to changing conditions driven by global warming. In time, these super coral might be transferred all over the globe in an attempt to halt the rapidly deteriorating coral reef.

In a testament to epigenetics, researchers show that it's possible that the marks of trauma can be transmitted down to subsequent generations.
Significant progress has been made in curbing poverty at the global level, but the rapid escalation of climate change could force developing regions to take two steps backwards. A World Bank report says as many as 100 million people could be pushed back into poverty by 2030 if no measures are taken, i.e. we go about business as usual
Have you ever wondered where do colours come from?
ZME Science reported earlier that Exxon Mobil might be liable for a RICO case similar to tobacco companies for withholding information about the risks of climate change and actively seeking to manipulate public opinion to favor its business. Now, a NY Times article reports New York Attorney General Eric T. Schneiderman is investigating the oil & gas company on suspicion that the company failed to mention critical information to its investors about the risks of climate change. A subpoena was issued on Wednesday evening to Exxon Mobil, demanding extensive financial records, emails and other documents.

Illegal marijuana farms often spray the vicinity of their crops with rodenticides to exterminate pests that lurk about and compromise the plants. The farmers will most often than sprinkle the rat poison on delicious treats like peanut butter or bacon to attract the rodents and kept them away from their precious cannabis. It's not just rats that fall for it though. Red foxes, spotted owls and, sadly, the endangered weasel-like fishers. According to a new study published in PLoS One, one in ten fishers die because of rodenticide ingestion from illegal marijuana farms.
"Any cars that are being made that don’t have full autonomy will have negative value. It will be like owning a horse," Musk said.
In what can only be called a medical oddity, doctors in Columbia found that a man's lung tumor wasn't actually caused by human cancer cells, but those of a parasite. Apparently, due to the patient's weakened immune system, cells from the parasite leached into the rest of the body and eventually developed into cancer. This is the very first reported case of a patient sick with cancer sourced from outside the body. It's literally alien cancer.
From Dec. 14, NASA is opening applications for its new astronaut crew. The minimal requirements aren't that strict, but as you might imagine to make the cut you'll have to prove you're better than a stellar class of applicants.
Before the official talks at the UN climate change summit start next month in Paris, each nation was invited to submit a pledge in which it details how it plans to reduce its carbon emissions. The plan is for the world's leaders to reach a sensible agreement such that the climate might avert warming by more than 2 degrees Celsius by 2100 past pre-industrial levels. The climate is already 0.9 degrees Celsius warmer. More than 155 countries have responded to the call, amounting to 128 Intended Nationally Determined Contributions (INDCs). Each country outlined the progress it wants to make differently, depending on how many resources they can dispose of and, of course, how serious they take the issue
Tyrannosaurus was one of the fiercest land predators ever, despite claims that the dinosaur was mostly a scavenger. While this is true to a degree, T-Rex was most definitely a hunter at heart even though the predator might have munched on a carcass or two from time to time. Apparently, the dinosaur even ate its own kind, a new study suggests.
The pineapple is the second most grown fruit crop behind bananas, with 85 countries producing about 25 million metric tons each year. It's sweet, exotic, tasty. Most people love it. But there's more to the pineapple than meets the eye. It's one of the most drought resistant crops out there, and scientists have now finally identified the genes that make the pineapple so resilient. By genetically engineering similar crops that share a genetic history with the pineapple it's possible to lend its drought resistance, and thus help curb the stress these face at the hand of global warming.
It's no secret that people nowadays spend most of their time indoors. In high-income countries, as many as 66% of jobs are in the service sector. If you fall in this category, you most likely work in an office environment, which might seem benign enough and boring, of course. However, not all office buildings are built the same. The various materials and furnishings can not only affect your performance at work, but also our health. A new study published in the journal Environmental Health Reports quantified the effects of air quality and found employees working in environments with minimum pollutants in the air performed up to twice as better on cognitive tests.
The famous inventor and tech pundit shares a few words on why he thinks humans will soon live forever.
Our solar system likely had a fifth gas giant in its initial configuration, but the planet was ejected by Jupiter a new study suggests.
Changes in surface height as measured by satellite altimeters suggest the Antarctic peninsula is experiencing a net gain of ice cover. The analysis suggests Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. However, this net gain slowed to 82 billion tons of ice per year between 2003 and 2008. Some parts the peninsula experienced substantial ice cover gain (East Antarctica), while other parts showed evidence of ice discharge (West Antarctica).
For the second time this year, however, the desert bloomed as thousands of dormant species of flowers and plants awoke after El Niño brought a rainy boom to the region.
Russia is locking up six women together to simulate a trip to the moon and back. But no one is taking this too seriously, it seems.
After using relaxation-response technique, such as yoga, meditation and even prayer, participants involved in a study coordinated by the Massachusetts General Hospital (MGH) solicited health care services 43% less frequently. The researchers involved in the study say simply learning how to relax to fend off anxiety and depression -second only to cancer and heart diseases in terms of health care costs - might significantly reduce the strain on the health care system. As such, more wide spread use of relaxation-response techniques could free up immense resources that can be diverted for chronic diseases.
When humans and nature work together, you can build some extraordinary designs. At MIT, living things are integrated using today's most advanced gear - like biological 3D printers - to help solve human needs. In this particular case, a suit that self-regulates in response to humidity (the trigger is sweat) so you can work, dance or explore more comfortably.
Of all the major conservative parties in the democratic world, the Republican Party stands alone in its denial of the legitimacy of climate science.
eam at Lawrence Livermore, helped by researchers from all around the world, announced the discovery of five new isotopes, adding to the already extensive list of 3,000 isotopes of 114 confirmed chemical elements. The exotic atomic variations discovered are one isotope each of heavy elements berkelium, neptunium and uranium and two isotopes of the element americium.
Science and medicine advances have stretched the life span further than ever. That's good news, but the quality of life is also important. People live longer now than ever, but they also live longer in sickness and suffering of both body and mind. Concerning the latter, a clear, sharp mind can be a rare thing once you pass a venerable age, but a team at the Paracelsus Medical University in Austria may be on to something. Working with mice, the researchers gave some of the elderly rodents a common drug called Montelukast that's used to treat asthma in children. To everyone surprise, the old rats started growing new brain cells and performed almost as well as the young in cognitive tests. If only the drug worked on people, too - we might find out soon.
Manure has been used as a plant and crop fertilizer since the dawn of agriculture, but since poop is naturally occurring it's been essential to the ecosystem far before humans evolved on this planet. But as the planet's megafauna has steadily dwindled, so has the megapoop significantly impacting the nutrient-recycling system. According to Joe Roman, a biologist at the University of Vermont, in some cases nutrient transport via pooping today is only 5% of what it used to be during the Ice Age.
This Wednesday at the Tokyo Motor Show, Honda Motors will unveil its brand new hydrogen car: the FCV (not its real name likely). According to Forbes, the car can run 435 miles on a tank full of hydrogen, which is more than 100 miles than any of Tesla EV. Moreover, a full fill only takes 3 minutes which means you can be back on the road in no time - provided you can find a hydrogen filling station. The biggest innovation, however, is Honda's new fuel cell system which is 10 times cheaper than the one on the FCX Clarity and takes as much space a typical V-6 engine.
