Under the Kyoto protocol most developed nations other than the US committed themselves to targets for cutting or slowing their emissions of the key greenhouse gases that cause climate change. The targets varied between nations. Some were allowed to increase their emissions by a certain amount; others were required to make significant cuts. The average…
The race is on to blame everything related to ecological change on human footprints – even the past can be re-framed as anthropocenic climate change and University of Massachusetts Amherst geoscientists have shown how to do just that, by using a biomarker from human feces in a completely new way to establish the first human…
Thawing permafrost covering almost a quarter of the northern hemisphere could “significantly amplify global warming” at a time when the world is already struggling to reign in rising greenhouse gases, a U.N. report said. Permafrost usually thaws on the surface during summertime, but now scientists say thaws reach up to 10 feet deep due to…
This fall, science writers have made sport of yet another instance of bad neuroscience. The culprit this time is Naomi Wolf; her new book, “Vagina,” has been roundly drubbed for misrepresenting the brain and neurochemicals like dopamine and oxytocin. Earlier in the year, Chris Mooney raised similar ire with the book “The Republican Brain,” which…
The hiding spots for the particles making up dark matter are narrowing, and the answer to this cosmic mystery could come within the next three or four years, scientists say. Dark matter is an elusive substance that is invisible and almost never detected, except by its gravitational pull. Yet astronomers say it likely makes up…
Could computers become cleverer than humans and take over the world? Or is that just the stuff of science fiction? Philosophers and scientists at Britain’s Cambridge University think the question deserves serious study. A proposed Center for the Study of Existential Risk will bring together experts to consider the ways in which super intelligent technology,…
Using an artificial intelligence technique inspired by theories about how the brain recognizes patterns, technology companies are reporting startling gains in fields as diverse as computer vision, speech recognition and the identification of promising new molecules for designing drugs. The advances have led to widespread enthusiasm among researchers who design software to perform human activities…
American denial of climate change hit bottom this month. Hurricane Sandy was the most powerful instance yet of mundane weather trumping abstract science to make people face the truth. “It’s Global Warming, Stupid!” screeched the cover of Bloomberg Businessweek, above a photo of a flooded street. Rising sea levels just moved from future threat to…
A U.S. start-up has turned to nature to help bring water to arid areas by drawing moisture from the air. NBD Nano aims to mimic the way a beetle survives in an African desert to create a self-filling water bottle capable of storing up to three litres every hour. The insect harvests moisture from the…
The EU’s debt crisis has sapped its ability to lead the way in ongoing global climate talks in Doha, and build on a fragile victory it clinched a year ago. The European Union is one of the few to have promised to sign up to a second emissions-cutting period under the Kyoto process, the only…
