Standard supply and demand analysis shows that competitive markets will deliver a given commodity up to the point where costs (as perceived by producers) equal benefits (as perceiver by consumers). When both producers and consumers internalize all costs and benefits, the result is efficient in the sense that the market does not dilapidate resources. An […]

Stability improved by allowing plasma closer to fusion reactor walls Researchers studying magnetic confinement fusion have found that allowing plasma to get closer to reactor walls may make the system more stable. It was a scary proposition because if their experiment didn’t work, it would have melted the reactor. Teams from China and the US […]

It seems that we are definitely heading towards the bio-based society, a new way of interacting with the environment where fossil fuels won’t be needed anymore and “ more natural ” processes for producing energy, food and materials will prevail. Remarkably, this bio-turn often involves highly advanced biotechnology and strict competitive targets, both facts that […]

Mars atmosphere stripped away by solar storms Solar storms have been stripping away the air on Mars, according to data collected by NASA’s Maven spacecraft. Researchers say this could help explain why Mars’ atmosphere became so thin so rapidly, turning a once warm planet with liquid water into the dry, desolate landscape it is today […]

People who are diagnosed with dementia may initially report problems on memory and/or language that affect their activities of daily living. Once factors such as depression, delirium, or mild cognitive impairment, are disregarded, these people are typically referred to a neurologist, radiologist, and neuropsychologist or speech therapist who will help them to understand the reason […]

Nerve cells that block itches in mice Scientists have found nerve cells in mice that can block itches caused by a light touch, which could one day lead to treatments for people suffering from chronic itch problems. Researchers genetically engineered mice without those spinal cord nerve cells, producing rodents that had the urge to scratch […]

Evidence of plague found in Bronze Age skeletons DNA testing of Bronze Age skeletons has found evidence of a plague outbreak that occurred thousands of years before the Black Death that devastated Europe in the 1300s. Researchers found enough Yersinia pestis DNA in skeletons that tested positive for the bacteria to produce complete genome sequences […]

As everybody knows, the people from Bilbao are born wherever they want. And, according to one of the most captivating conjectures in contemporary archaeology, this might have been so in a totally unexpected way even from many millennia ago. The conjecture I am referring to is the ‘Solutrean hypothesis’ about the first human population of […]

“‘Is there no way,’ said I, ‘of escaping Charybdis, and at the same time keeping Scylla off when she is trying to harm my men?’” -Homer, The Odyssey Conventional cost-benefit studies are based on marginal analysis. A decision to undertake a project should be made if, with respect to the actual situation, it provides more […]

Still trying to make sense of New Horizons’ Pluto data Pluto’s frozen mountain ranges Norgay Montes and Hillary Montes are among many of the dwarf planet’s features described in the first published study of data gathered so far from the close flyby of NASA’s New Horizons spacecraft in July. The mission scientists acknowledge they still […]
