Researchers at Swansea University, UK and Uppsala University in Sweden built a mathematical model that explains how one single sheepdog can round up herds made of up to 100 sheep. Their conclusion suggests that the dog needs only to follow two simple mathematical rules.
Either when someone’s late for a date or you need to queue in line, our patience becomes tested. Some people handle the waiting better than others, leading us to the idea that patience is a virtue that differs from person to person. But what is it exactly that helps us remain patient, and why do […]
From the tropics to the poles, bird populations all over the world are facing a sharp decline, cornered by climate change and exposure to man-made biochemicals, namely pesticides. According to to BirdLife International, one in eight species (more than 1,300 species) of birds are under serious threat of becoming extinct. The list includes iconic birds of pray and song like eagles, vultures, swifts or swallows, but also seabirds like sandpipers, pelicans or storks.
Researchers from Stanford have found a way to split water into oxygen and hydrogen using very little energy; the hydrogen they obtain could be used to power fuel cells in zero-emissions vehicles. I’m quite excited for cars that run on hydrogen, which are set to hit the market in 2015; but while they are always presented as […]
Researchers have pinpointed the source of a huge environmental threat for AIDS patients – the source of a fungal infection which has been plaguing Southern California for years; it literally grows on trees. The finding was based on the research project of a 13 year old. Cryptococcus gattii, formerly known as Cryptococcus neoformans var gattii, […]
A while ago, we were telling you about the infamous “zombie ant fungus” – a parasitic fungus that reproduces by manipulating the behavior of ants. It’s one of the most gruesome acts in nature – the parasite fungi infect tropical ants, literally taking control of their actions, ultimately leading the infected ant to march to its death […]
A team of researchers from the Aarhus University in Denmark and CalTech has developed an origami-inspired method of organizing molecules on the nanoscale. The team has modeled RNA, DNA’s close cousin into complicated shapes using the technique. Together with DNA, RNA comprises the nucleic acids, which, along with proteins, constitute the three major macromolecules essential for […]
Bacteria living in obscure environments use an extremely rare process to harvest energy and produce oxygen from sunlight – but they don’t use visible light, they use far-red light. “We have shown that some cyanobacteria, also called blue-green algae, can grow in far-red wavelengths of light, a range not seen well by most humans,” said Donald […]
Seismic activity is continuing at the Bárðarbunga volcano and an eruption may still take place, scientists said on Sunday, but the emergency level has been downgraded from red to orange. “There are no indications that the activity is slowing down, and therefore an eruption can not be excluded,” the Icelandic Met Office said. Over 700 earthquakes […]
A whole functional organ has been successfully grown in animals for the first time; a group of Scottish researchers created a group of cells which, when transplanted into a mouse, developed into a fully functional thymus – a critical part of the immune system. The findings could lead to a revolution in organ transplant. The […]
A worrying report states that over 500 bubbling methane vents were found on the seafloor off the US east coast. The unexpected finding suggests that there are large volumes of the gas contained in a type of sludgy ice called methane hydrate and as global waters continue to heat up, the methane will be released in large […]
A new study of over 10,000 women has shown that women who breastfeed after giving birth have significantly lower chances of post-natal depression than their counterparts who didn’t. There are still many things we don’t yet understand about breastfeeding, as this study highlights – mothers who planned to breastfeed and were actually able to do […]
The physical properties of the ultra-white scales on certain species of beetle could inspire researchers to make better, whiter paper, plastics or paint, using far less material. The Cyphochilus beetle, native to South-East Asia, is whiter than paper or even milk teeth. The whiteness of its body is caused by a thin layer of a highly […]
Depending on where you live, bike stealing can be a distant threat or a constant worry, but in most parts of the world, people would rather be safe than sorry, tying their bikes to trees or fences or whatever they could find. But that may very well change in the near future: three engineers from […]
A medicine administered even up to 3 days after infection can save monkeys from the Marburg virus – an incredibly dangerous pathogen closely related to Ebola. “This clearly starts to move into the realm of being a therapy, rather than a post-exposure treatment,” says virologist Gene Olinger, principal science adviser for contract-research organization MRIGlobal in […]
If you thought research in airplanes only applies to the military, you’re wrong. While most of the money spent for airplane research does go to the military, a smaller chunk of it goes to space research, and another part goes to private air travel. Now, a company from the UK has almost developed an engine […]
It’s one of the most remarkable adaptations in the animal world – growing a tail or a limb. Some lizards do it, salamanders do it, and by learning how they do it, we may soon be able to do it as well; with technology, that is. A team of researchers have discovered the genetic “recipe” for […]
A new study shows that last an incredible 63 trillion gallons of groundwater were lost in the Western US alone – so much that it’s actually causing the ground level to rise. The Earth has lifted up about 0.16 inches over the last 18 months in the area, and up to 0.6 inches in the Californian […]
Observations of climate change often report a “missing heat” – a hiatus in the global warming, which went unaccounted for; but now, a new study concludes that the heat absent from the Earth’s surface for more than a decade is plunging deep in the north and south Atlantic Ocean, and this is part of a naturally […]
Between 5,000 and 8,000 gallons of diesel were spilled into the Ohio River on Monday, but officials say drinking water in the area is safe. Duke Energy is responsible for the spill, which happened during a “routine transfer”. While the company is still investigating, Duke spokeswoman Sally Thelen told the Inquirer that the spill may […]
Eating less meat could protect the driest areas of the world, saving much needed water. Reducing the use of animal products is very significant in all parts of the world, as meat production requires more water than other agricultural products, they say. In case you don’t know, every food we eat (and every product we use) has […]
For billions of years, nature has been harnessing the energy from the sun through photosynthesis. This way, plants, algae and cyanobacteria use sunlight to split water and produce energy-rich chemical compounds from carbon dioxide (CO2). This energy is then transferred to animal that eat these plants, and animals that eat plant-eating animals, including us humans. It’s […]
California is facing one of its direst drought streaks, and only last year it came out of its warmest winter on record. Clearly, things aren’t looking that good and the most vulnerable resource to these conditions is at the same time the most valuable: water. Desperate times, call for desperate measures, and this means in […]
While most of the hype is centered around biotech efforts that try to engineer human organs from scratch in the lab, a better idea might be to grow human-compatible organs in foreign hosts. Researchers at the National Heart, Lung and Blood Institute (NHLBI) of the National Institutes of Health genetically modified pig hearts with some human […]
We’re used to reporting year after year how China’s coal consumption is increasing and how they are polluting more and more. But this is the first year in over 2 decades when the number hasn’t increased. Could China’s coal boom be over? While positive signs have been emerging from China for well over a year, […]
It seems quite intuitive, but scientists have officially proved it – sharing common knowledge with someone makes you more likely to cooperate with him. This provides valuable insight into how altruism works, and how groups can cooperate towards a common goal. There have been plenty of studies into altruism, but fewer have studied its lesser […]
A mosaic of more than 3,150 high-resolution satellite images creates the best continent-wide view since 1997. The result is the one you see below: The over three thousand pictures were taken in the Southern Hemisphere’s autumn of 2008, and tiled together into a coast-to-coast view of the entire continent with its coastal waters. The result is […]
Canada’s most famous (and from what I can find, only) beer-cooler turned hitchhiking robot has finally completed its 6,000-kilometre journey across Canada, blazing rides from Halifax reaching Victoria late Saturday; and he did it with style: I’m on a boat. Well, a ferry to be exact. Victoria, I’m on my way. #hitchBOT @BCFerries pic.twitter.com/SPewf9rIq1 — hitchBOT (@hitchBOT) […]
Russian researchers who were conducting experiments on the surface of the ISS were absolutely shocked when they found sea plankton, just outside of the space station. Other reports mention that they found them while they were polishing some parts of the ISS, but that’s not really important here: they found real, living, sea creatures in space. Samples […]
A while ago, we were telling you about the lab in Netherlands which artificially created a hamburger, making it the first lab-grown hamburger in the world. Now, a team from California has followed in their footsteps, creating the first cheese that does not originate from milk. A group of biohackers from Counter Culture Labs in Oakland, and BioCurious in Sunnyvale, […]
The world has reached what is called ‘World Overshoot Day‘ – the point in the year when humans have exhausted supplies such as land, trees and fish and outstripped the planet’s annual capacity to absorb waste products including carbon dioxide. But that’s not half of it – things are actually getting worse, with the planet […]
A while ago I wrote about the disheartening status quo of energy today: frack now, ask questions later. In the article, I argue that there’s a disproportion between the amount of hydraulic fracturing (9 out of 10 wells in the US are fracking wells) and the number of research articles that discuss the bio impact […]
This bacterium has a lot in common with power companies. Power companies use copper wires to channel electricity (and therefore, electrons), and this bacterium developed a mechanism to do something similar: in the absence of oxygen, it grows nanowires from its own body through which it pushes electrons to nearby rocks. This is how it […]
People from Beijing can now use one of the city’s 34 newly installed facilities which allows them to pay for public transportation or charge their phone credit with empty plastic bottles. China is the world’s biggest polluter, and will likely stay so for years and years to come. The growth of their economy has been […]
Listening to loud music has been shown time and time again to affect hearing in a negative way. The damage becomes more pronounced with age, leading to difficulties in understanding speech. A new analytic study by researchers at University of Leicester examined the cellular mechanisms that underlie hearing loss and tinnitus triggered by exposure to loud […]
Most societies in Africa are leading an uphill battle in their attempt to ensure safety, good health and food security. But for African animals, it’s even worse. Poachers alone killed an estimated 100,000 elephants across Africa between 2010 and 2012, raising new concerns about the species’ survival. Poaching in Africa is huge – the term […]
A study by researchers at Harvard University found that children from a tender age have an advanced idea of fairness and are willing to step forward and pay a personal price to intervene a situation they perceive as an unfair. This decision is group-biased dominant in children aged six or less, but those aged eight or more were found to intervene in unfair situation and stop any selfish behavior, whether or not the victim was a member of their group.
Ten years ago, the European Space Agency launched the Rosetta probe tasked to orbit a comet for the very first time and study it up close with unprecedented detail. Six billion miles later, the probe reached its target, the four-kilometer wide 67P comet, and has beamed back some of the most breathtaking images of a […]
Lead-acid car batteries used to be the norm, but luckily we’re seeing a massive shift towards more efficient and environmentally friendly alternatives like lithium-ion. Still, there are fleets of hundreds of millions of cars that still employ these archaic and toxic batteries. Typically, manufacturers try to have car owners bring their old lead-acid batteries, which […]
Researchers at the Max Planck Institute of Immunobiology and Epigenetics (MPI-IE) re-activated the expression of an ancient gene in mice. To their surprise, the gene in question which is dormant in all mammalian species caused the mice to develop fish-like thymus. The thymus is an organ of paramount importance to the adaptive immune system, but in […]
Chemists led by Nobel laureate K. Barry Sharpless have used what is called click chemistry to uncover unprecedented, powerful reactivity. This opens a new “chemical galaxy” of molecules, potentially paving the way for making drugs, plastics and unprecedented smart materials. Click chemistry is a term applied to chemical synthesis tailored to generate substances quickly and reliably by joining […]
It looks like a painting from Salvador Dali – but Hallucigenia was very much real. Truly one of the most surreal creatures to ever walk the face of the planet, it was finally deciphered and understood (at least partially) by paleontologists, after 4 decades of study. The process discovered not only its position in the […]
I was reading this morning how excited some journalists were in reporting “the biggest oil discovery in decades”, and I got a little curios: how big is it? According to US oil company Apache, the field could have potentially up to 300 million barrels of oil in place – Australia gets a lot of oil, […]
A parasitic plant called the dodder, which essentially acts like a 'vampire' upon its unsuspecting prey. A new research found the dodder actually communicates using DNA with its host in order to lower its defenses. A true vampire to the end - it needs an invitation to step in.
New research has shown that a big asteroid is well on its way to hitting Earth in 2880 - and by that I mean it has a 1 in 300 chance of actually hitting our planet, but it's still the likeliest celestial body to hit the Earth in the foreseeable future.
Early modern human populations were culturally diverse and sometimes exchanged tools helped by river networks in a then savanna rich Sahara, according to the biggest ever comparative study of stone tools dating to between 130,000 and 75,000 years ago. At least fourdistinct populations, each relatively isolated from each other, have been identified as possessing distinct cultural practices.
A first of its kind study conducted at the University of Colorado Denver looked at how city design affects populace health. Older cities, initially built for pedestrian traffic in mind were found to harbor less cases of diabetes and other diseases than those with broader streets and fewer intersections. While some people can stay healthy and stick to exercising habits no matter where they live in, the study suggests that in general cities which are optimized for vehicle traffic discourage walking and other healthy activities.
In a breakthrough in robotics, researchers have programmed a swarm consisting of a whooping 1,024 members which can assemble in programmable 2-D shapes. The demonstration might provide insights in how natural self-assembling swarms operate, like ants who join up to form bridges for the good of the colony.
Researchers believe they have found seven dust specs from outside the solar system. This is the first time we have the chance to directly analyze interstellar matter. The material was probably ejected from a supernova.
Ebola is starting to get more and more worrying. Now, a team of WHO researchers has announced that the outbreak may have been underestimating, as it spreads much faster and affects more people than previously thought.
