New DNA analysis reveals that, before their mysterious disappearance, the Norse colonies of Greenland had a “near monopoly” on Europe’s walrus ivory supply. An overreliance on this trade may have contributed to Norse Greenland’s collapse when the medieval market declined. »
New research shows that five grams a day sodium consumption does not increase health risks, however dramatic reductions in salt consumption may even prove harmful. »
Watermelon rind, usually discarded as waste, has been shown by researchers in Pakistan to be capable of cheaply and efficiently removing arsenic from groundwater. »
Using magnetoencephalography, researchers showed that while the human brain is still able to perceive sounds during sleep, it is unable to group these sounds according to their organization in a sequence. »
A technology developed by ARS scientists is being used to boost resistance to a disease in potatoes that can destroy entire fields and often requires growers to repeatedly spray fungicides. The technology also may be used to breed improved varieties of many other important crops. »
Australian scientists have test driven two cars powered by a carbon-free fuel derived from ammonia. A team from the Australian government’s research agency, the CSIRO, says the pioneering technology will allow highly flammable hydrogen to be safely transported in the form of ammonia and used as a widely available fuel. »
The prospect of a vaccine to stop gaining weight by eating fat is getting closer to reality after scientists found compelling evidence linking obesity to an infectious virus. »
A team of scientists, including a volcanologist and mathematician from the University of Cambridge, discovered the phenomenon through detailed observations of gas emissions from Kīlauea volcano in Hawaii. »
Investigators successfully reversed hair loss, hair whitening and skin inflammation linked using an experimental compound. »
A correlation between obesity and genetics has been found to be modified by diet. A research group led by a U.S. Department of Agriculture scientist found that a specific gene—APOA2—can result in a higher body mass index. »
The severity of drought conditions during the demise of the Maya civilisation about one thousand years ago has been quantified, representing another piece of evidence that could be used to solve the longstanding mystery of what caused the downfall of one of the ancient world’s great civilisations. »
New research reveals that human eyes can be indicator of personality type, simply by the way they move. »
Researchers have identified a group of materials that could be used to make even higher power batteries. »
Researchers developed magnetic elastomeric composites that move in different ways when exposed to light. »
A new paper published this week suggests that liquid water may be sitting under a layer of ice at Mars' south pole. »
A team of researchers from China, Canada, the United States, and Australia published on Wednesday their discovery of an early fossilized baby snake, reportedly the oldest ever found, in a piece of amber in the middle of a sandstone deposit in Myanmar. »
The creation of artificial embryos has moved a step forward after an international team of researchers used mouse stem cells to produce artificial embryo-like structures capable of ‘gastrulation’, a key step in the life of any embryo. »
A research aimed at engineering plants to make them able to create their own fertilizer in the future. »
Massive fruit trees in the Thailand evergreen forest need massive herbivores to help spread their seeds, according to a new study. »
Scientists supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have discovered a set of powerful, broadly neutralizing antibodies (bNAbs) in the blood of EVD survivors. »
Nitrogen is the main nutrient added to cereal crops like corn, which makes them grow faster and stronger. But too much of a good thing could sometimes have negative outcomes. Too much nitrogen can run off with rainwater or leach through to soil and contaminate groundwater. »
A tiny silicon-based device was created by researchers making them able to harness heat from waste and convert it to it into DC electrical power. »
Injecting senescent cells into young mice results in a loss of health and function but treating the mice with a combination of two existing drugs cleared the senescent cells from tissues and restored physical function. The drugs also extended both life span and health span in naturally aging mice. »
An international team of astronomers has discovered an ancient and dramatic head-on collision between the Milky Way and a smaller object, dubbed ‘the Sausage galaxy’. »
Russian scientists believe that terrestrial bacteria that were sent to space and returned to earth now pose a threat to the existence of life on Earth. »
Other than their purity, flaws in Diamonds may be holding the key to a new type of communications with high security. Diamonds were used by researchers to preserve fragile quantum information over long distances. »
The makeup of microbial species—the microbiome—in a honey bee queen’s gut changes slowly as she ages, while a worker bee’s microbiome changes much more rapidly, according to a new study published by Agricultural Research Service (ARS) scientists. »
Some bacteria can release toxins that provoke their neighbors into attacking each other, a tactic that could be exploited to fight infections. »

It's been known for years that humans and other mammals possess an antiviral gene called RSAD2 that prevents a remarkable range of viruses from multiplying. »
A landmark international study shows that the Great Barrier Reef has suffered 5 death events in the last 30,000 years. The groundbreaking study of the world’s largest reef system reveals that these events were driven mostly by variations in sea level and associated environmental changes. »
Data from NASA's Cassini spacecraft reveal complex organic molecules originating from Saturn's icy moon Enceladus, strengthening the idea that this ocean world hosts conditions suitable for life. Research results show much larger, heavier molecules than ever before. »
Natural predators of common agricultural pests can save farmers money spent on insecticides while being friendly to health and environment, a study carried out in the cotton fields of China suggests. »
Some of the earliest complex organisms on Earth – possibly some of the earliest animals to exist – got big not to compete for food, but to spread their offspring as far as possible. »
Taking a walk may be a good opportunity to mentally review your to-do list, but using the time to instead be more mindful of your breathing and surroundings may help boost your wellbeing, according to researchers. »
