Your microbial cloud is your "signature"

Humans are walking ecosystems. Each of us carries around about 100 trillion microbes in and on our bodies, which make up our microbiome. The quality of this bacterial community has a lot to say about our health and well-being. The blend of microbes is also surprisingly unique, which says a lot about who we are […]

New species of duck-billed dinosaur discovered in Alaska's North Slope

A new species of plant-eating dinosaur was discovered in Alaska, a variety of hadrosaur -- duck-billed dinos that roamed in herds, said Pat Druckenmiller, earth sciences curator at the University of Alaska Museum in Fairbanks. Researchers named the creature Ugrunaaluk kuukpikensis (oo-GROO'-nah-luk KOOK'-pik-en-sis), meaning "ancient grazer," chosen by scientists with assistance from speakers of Inupiaq, the language of Alaska Inupiat Eskimos.

New technique can identify any known virus in a blood sample - without fail

Ian Lipkin, a virus hunter from Columbia University, along with fellow professors Thomas Briese and Amit Kapoor have designed a new system, known as VirCapSeq-VERT, that they claim can detect any known human virus in a blood sample.

Florida quarantines farmlands to contain the Oriental Fruit Fly

Florida's farmlands are under attack by a highly destructive pest, the Oriental Fruit Fly, and authorities have quarantined some 85 square miles of land and the food grown there in an effort to contain the insect.

3D stacked computer chips could make computers 1,000 times faster

Computer chips today have billions of tiny transistors just a few nanometers wide (a hair is 100nm thick), all crammed up in a small surface. This huge density allows multiple complex operations to run billions of times per second. This has been going on since the '60s when Gordan Moore first predicted that the number of transistors on a given silicon chip would roughly double every two years. So far, so good - Moore is still right! But for how long? There's only so much you can scale down a computer chip. At some point, once you cross a certain threshold, you pass from the macroworld into the spooky domain of quantum physics. Past this point, quantum fluctuations might render the chips useless. Moore might still be right, though. Or he could be wrong, but in a way that profits society: computer chips could increase in computer power at a far grater pace than Moore initially predicted (if you still keep Moore's law but replace transistors with the equivalent computing power). This doesn't sound so crazy when you factor in quantum computers or, more practical, a 3D computer architecture demonstrated by a team at Stanford University which crams both CPU and memory into the same chip. This vastly reduces the "commuting time" electrons typically have to go through while traveling through conventional circuits and makes them more efficient. Such a 3D design could make a chip 1,000 faster than what we typically see today, according to the researchers.

The reason why we haven't heard from aliens yet is encryption, Edward Snowden says

The biggest pariah of the century, NSA whistleblower Edward Snowden, had a "geek to geek" hour long talk with Neil DeGrasse Tyson, part of the StarTalk radio show. The two had an interesting discussion about lots of stuff from science, to chemistry, to space. Even 9/11. It's worth mentioning that Snowden made his presence felt through a robotic telecomm machine which he remotely controlled from Moscow, his asylum. Perhaps, the most interesting moment from the episode is their chat on encryption, a topic where Snowden is particularly an expert. It's so obvious I'm surprised I've never heard this idea before: the reason why we've yet to pickup any messages from an intelligent extraterrestrial species might be because this data is encrypted.

365 million year old trilobites show first signs of molting

Trilobites were some of the most dominant creatures on the face of the planet, thriving from the mid Cambrian 521 million years ago to the start of the Mesozoic, 250 million years ago. Paleontologists have now found the earliest evidence for molting - a trilobite shedding its skin 365 million years ago.

Watch these drones build a rope bridge that's safe to walk on

Drones are often feared as instruments of destruction, and as John Oliver pointed out, in some parts of the world, people fear blue skies because that’s when the drones strike. But this technology isn’t only used to destroy – it can also be used to create, as demonstrated by these very efficient quadrocopters building a rope […]

US puts twice as much trash in landfills than previously thought

Americans are sending much more trash to landfills than federal agencies estimated - twice as much, according to a new study.

AI passes math test like an average high-school student

Researchers from the University of Washington and the Allen Institute for Artificial Intelligence (AI2) have developed a computer software that scored 49% on high-school geometry SAT tests - an average score for a human, but a great one for current AIs.

Cleaning smudge using only water and ultrasounds

Usually, we have to use all sorts of disinfectants, soaps and detergents to scrub away smudge, be it sticky, oozy or greasy. This is not only annoying during housekeeping, but also following medical procedures when instruments have to be cleaned. Researchers at University of Southampton have been working for several years on a different kind high tech solution. They developed a gun-shaped device called the StarStream equipped with a special nozzle that injects water bombarded with ultrasound waves. The mix is so powerful that virtually any kind contamination can be removed.

UK scientists want to modify genes inside a human embryo

A team working at the Francis Crick Institute in London applied to the Human Fertilisation and Embryology Authority for a permit that would allow them to edit genes in a human embryo. If allowed, this would lead to the very first genetically modified embryo in the UK. The scientists claim they need approval to do basic research that may " improve embryo development after in vitro fertilization (IVF) and might provide better clinical treatments for infertility,” and not for clinical research. Either way, the controversial practice is banned in all Western countries and virtually banned, although not explicitly, in the US.

Chimps enjoy the movies just as much as we do

A video of an ape, breaking out of its cage and attacking; the victim -- a human scientist, that picks up a small red hammer and defends himself, battering the primate ran amok. It sounds like a pretty gruesome video, bound to have animal right's activists redouble their efforts to see the heartless jailers brought to justice. But hey, wait a minute... Apes don't wear sneakers.

Maps that explain today's major migration routes

Syrian refugees are making headlines all over the world, but while their story is worth covering, there are millions other refugees in Asia, Central America or Africa that are in the same boat. According to the U.N., 59.5 million people were displaced due to “persecution, conflict, generalized violence, or human rights violations” in 2014 or 8.3 million more than the year before. To escape persecution, refugees take hidden routes out of their own country which are often controlled by smugglers and can be extremely dangerous to cross. Everybody was heartbroken to learn about the story of three-year-old Aylan Kurdi, who was found washed ashore in Turkey, but few know that 2,900 other people died drowned or asphyxiated on their way to a safe haven this year alone. National geographic just released five great maps that explain the global forced migration patterns

New research reveals the origins of the Polish "vampires"

Middle Age Europe was a place ruled by superstition and mythical beliefs - at least some parts of it were. Now, researchers are trying to figure out what made some people in Poland believe there was an 'outbreak of vampires' in the 17th and 18th century.

Innovation 101 - migratory study offers insight into how humans develop new technology and ideas

The human inovation process is more of a slow, steady climb than a sum of great leaps, a new University of Reading study shows. Our minds tend to innovate by adding small improvements through trial and error report the scientists, who studied one of the most important cultural events in human history - the migration of the Bantu-speaking farmers in Africa some 5,000 years ago. Mark Pagel, Professor of Evolutionary Biology at the University, led the study.

Pharma startup raised the price for a life-saving drug from $13.5 a tablet to $750

A dubious pharmaceutical startup recently bought the rights to a drug that treats a parasitic infection, then raised the price 500-fold seemingly over night. The drug targets a somewhat rare condition that affects immune compromised pregnant women, but also malaria and AIDS. Ironically enough, it was developed by a much hated big pharma company, GlaxoSmithKline, in 1953 and used to cost $1 a pill only a couple years ago. It has since traded hands twice, before coming under the control of Turing Pharmaceuticals, a start-up run by a former hedge fund manager.

Your hygiene and cosmetic products are killing the oceans

Eight trillion microbeads are polluting the US waters every day. As the plastic beads are very small, they breach through the water filtration systems, affecting wildlife and ultimately, humans. The main culprit for this microbead invasion is the cosmetics industry, where the particles are used as exfoliating agents and in toothpastes.

Scientists find the earliest creature to stand tall on four legs

About 260 million years ago, this pre-reptile might not have looked like much. With its knobby face and about as big as a cow, Bunostegos akokanensis was actually pretty remarkable. According to a new analysis, it was actually the first creature to walk upright on all four legs, maintaining a fully erect gate.

Scientists develop new tree of life, with all known organisms

After years of analyzing and reclassifying some 2.3 million species, a group of international researchers from eleven institutions were able to create the most advanced and up to date tree of life. This all inclusive tree is actually pieced together by compiling thousands of other, smaller trees.

In 2017, Norway will become the first country to shut down FM radio

The Norwegian Ministry of Culture has finalized a transition date from Frequency Modulation (FM) radio to Digital Audio Broadcasting (DAB) radio. They will thus become the first country in the world to switch completely from FM radio.

Sweden tests the six hours work day, with impressive results

A group of elderly-care nurses working at the Swedish Svartedalens elderly home participated in the first controlled trial of shorter work hours the country held for a decade now. In February, the they switched from an eight-hours to a six-hour working day for the same wage, in an effort to improve productivity and quality of life.

Today's GOP candidates don't deny climate change anymore, but think it's useless to act instead

This Wednesday, Sen. Marco Rubio, New Jersey Gov. Chris Christie, and Wisconsin Gov. Scott Walker were engaged in a two hour long debate on CNN. In 120 minutes, climate change was only treated for three minutes, which to me is saddening since it shows the moderators care as little about the effects of climate change on this country and the world at large as the Republican Presidential candidates.

Antidepressant Paxil, thought to be safe, proven unsafe for teenagers

Fourteen years ago, a leading drug maker conducted a study which concluded that Paxil, an antidepressant, was effective and safe for teenagers. But now, a major medical journal published an analysis concluded the opposite.

Is going nuclear the key for more sustainable energy?

The world is at an extremely dangerous crossroads: if we keep using non-renewable hydrocarbons and coal the way we have, we'll be rising global temperatures to a point where the consequences are extremely dire, but in many parts of the world, renewable energy is simply not cheap enough, and people don't want to pay for it. Faced with this conundrum, we may have an unexpected ally that could solve our problems: nuclear energy.

The IgNobel Awards 2015: What all the buzz is about

It’s the science that makes you laugh, and then makes you think. It’s a tradition not nearly as established as the Nobel awards, and not nearly as reputable – since 1991, some of the planet’s best and most creative researchers have gathered each year to celebrate and appreciate the most ridiculous scientific discoveries which could […]

Two supermassive black holes set for a collision that will shake the cosmos itself

That's what I call fatal attraction: two supermassive black holes are "dancing", drawn together by each other's humongous gravitational attraction, set for a collision that will likely send ripples through the very fabric of space-time.

Global warming lets mosquitoes thrive in the Arctic, threatening wildlife

The Arctic is overrun with giant mosquitoes: larger, furrier versions of the mosquitoes we all know and hate. As temperatures in the Arctic continue to rise, these mosquitoes can not only brood for a longer period of time, but they can survive more, in higher numbers. According to a new study published in the Proceedings of the Royal Society B: Biological Sciences this is a major problem, and one that will continue to grow as the planet gets hotter.

Antibacterial soap is no better at killing germs than regular soap

Regular soap is really good at killing bacteria, but most people feel that antibacterial soaps are even better. After all, they're antibacterial, right? Well, according to a thorough research, that's not true at all - regular soap works just as good as antibacterial soap.

Trio of individually ineffective drugs efficiently kills MRSA in mice

A research team has demonstrated the effectiveness of a 3-antibiotic cocktail that kills methicillin-resistant Staphylococcus aureus, or MRSA, in all mice that were treated with it.

Join the great Californian Trash Treasure Hunt, and help keep the ocean clean

Ok ok it's not technically called that, but the California Costal Cleanup Day is definitely something you should check out this Saturday if you like finding cool stuff and wish your beach looked less....garbage-y. For 31 years now, thousands of volunteers all over the world come together, put on the strongest pair of gloves they can find, and go scour the coast, lakes, rivers and their surroundings, picking up what we throw out the rest of the year.

Scientists find the world's largest volcanic hotspot track

Scientists have discovered the longest chain of continental volcanoes in the world, stretching almost 2000 km (1200 miles) on Australia's coast. The volcanic track includes 15 volcanoes formed over 30 million years ago.

Wolves are better than dogs at solving problems, study finds

An experiment has found that domestic dogs have lost some of their problem solving abilities, and wolves currently do a much better job than them. In her paper published in the journal Biology Letters, they describe this result, and also offer a possible explanation.

World's most useless scientific discoveries [infographic]

Every year, the Ig Nobel Prize is awarded to ten lucky winners. To qualify, you need to publish research in a peer-reviewed journal that is considered "improbable": studies that make people laugh, but think at the same time.

8.3 Magnitude Earthquake strikes Chile

A massive 8.3 magnitude Earthquake struck the northern coast of Chile on Wednesday night, killing at least five people and causing buildings to sway in the capital city of Santiago. Following the earthquake, waves of up to 4.5 meters were reported in some areas of the coast. About one million people were evacuated.

Wild animals banned in Netherlands circuses

The Netherlands has joined the list of European countries that have banned wild animals from their circuses. The Netherlands will be prohibiting the use of all wild animals for performance (except performance zoos).

Exxon's own scientists confirmed climate change - back in the 70s!

As a new investigation showed today, the scientists of the biggest oil company in the world, Exxon Mobil knew about climate change back in the 70s - but they still helped block the Kyoto protocol in the 90s, and invest massive amounts of money into climate skepticism propaganda. Today, 9 out of 10 funded climate change deniers can be linked to Exxon.

Native Americans were the first to make caffeinated drinks

The humble bean is the first thing some of us reach for in the mornings, it's our companion during breaks and comes to warm us up on cold winter days. We've come to rely on coffee, due to the caffeine it contains, to wake us up when the night is short and full of terrors, and keep us going when the going gets rough. A new study from the University of New Mexico's researchers however shows how the people of the Southwestern United States and Northwestern Mexico were drinking caffeinated beverages as early as 750 AD, over 1,200 years ago.

The mass of a supermassive black hole relative to the Sun explained in one crazy GIF

While the name might fool you at first glace, black holes are anything but empty.

Close relationships make handling stress easier

New research has found evidence of emotional burden sharing (also known as load sharing) between partners in a close relationship. The study, co-authored by Queen's University PhD candidate Jessica Lougheed, found that a strong personal relationship can help ease stress when placed in difficult situations.

Ultrasounds used to control neurons in a worm's brain for the first time

By 'tickling' select membrane channels you can effectively control neurons, by activating or deactivating cells. You can do this using electrical currents, like we see very well illustrated in brain-computer interfaces; light (the field of optogenetics); and sound (sonogenetics). Yes, sound. This was only recently demonstrated by researchers at Salk's Molecular Neurobiology Laboratory who used ultrasounds to control neurons in the nematode Caenorhabditis elegans.

Tuna and mackerel populations suffer disastrous 74% population decline

According to a new report by the WWF, we're very close to losing fish species that are not only important for their ecosystems, but that are vital to our food security. The main culprit, as it usually happens, is humans: we've almost wiped out tuna and mackerel through overfishing.

Researchers devise first electric circuit with a magnetic insulator, which was thought to be impossible

A team of Dutch and Belgian researchers demonstrated an electric circuit coupled with a magnetic insulator. The circuit uses so-called 'spin waves' instead of electrons to transmit information, something that was considered unpractical until not too long ago. The findings could help lead to a new class of electronics which are far more efficient since there's less heat loss.

Pest-controlling Bats provide a service worth at least $1 billion to farmers

Corn farmers around the world owe bats at least $1 billion, seeing how they ward off pests like insects. The findings were made by a group at Southern Illinois University who devised an experimental exclosure in order to estimate bats' contribution to pest control.

Bees get much needed win as US court rules against neonicotinoid pesticide

Bee numbers have been dropping at alarming rates, and the growing consensus seem to be that only limiting pesticide use (especially for some pesticides) can save them. Now, a US court overturned federal approval for a new formulation called sulfoxaflor, basically banning the pesticide.

Beneath Enceladus' icy crust lies a global ocean of liquid water

Saturn's moon, Enceladus, is covered in a thick icy crust, but beneath it might lie an ocean of liquid water despite there are minus 201 degrees Celsius on the surface. This is a theoretical assumption, which is however backed by very solid indirect evidence. Gushing plums of water from the moon's south pole also point to this conclusion. If this is true, Enceladus can be envisioned like a gourmet candy: a hot core (maybe chocolate?), surrounded by a layer or water, and all covered in a crunchy crust of ice.

Scientists engineer yeast that creates active marijuana compound, THC

Scientists have genetically modified yeast to produce the main psychoactive substance in marijuana, THC. Responsible for most of weed's effects (including the high), THC can also be used for medical purposes, to treat symptoms of HIV infection and chemotherapy.

This simple code can increase your smartphone battery life by 16% - and yes, it's free

Researchers at Purdue University in the US have developed a new tool for Android users that could increase your battery life by 16%.

Doctors transplant world's first 3-D printed rib cage

Reconstructive surgery just got an upgrade after a patient who had lost four ribs and part of his sternum had a 3-D printed titanium replica fitted instead. This was the first such procedure. Although the operation was a sound success with the replica matching like a glove, doctors say that this sort of intervention is only for really extreme cases. You can't become Wolverine overnight, not exactly at least.

This cheap catalyst might finally make the hydrogen economy work

Hydrogen is a great medium for storing energy. It can be used as an alternative to batteries to store the excess energy from renewable energy systems like solar panels or wind turbines, and can be released from a tank to power a vehicle equipped with fuel cells. More than a decade ago, these prospects hyped the so called "hydrogen economy". Governments and funding agencies drew up ambitious plans to develop cheaper fuel cells and to enable cars to store practicable quantities of hydrogen. In 2003, President George Bush committed $720 million to the research effort. But eventually... it all turned out to be a pipeline dream mostly because of two shortcomings: hydrogen is very expensive to store and make; from renewable sources at least.
