Rich countries spend five times more on fossil-fuel subsidies than on aid to help developing nations cut their emissions and protect against the effects of climate change, the Oil Change International campaign group said. In 2011, 22 industrialized nations paid $58.7 billion in subsidies to the oil, coal and gas industries and to consumers of…
Murder is contagious and may spread like the flu, new research suggests. The researchers relied on the same techniques public-health officials use to track the spread of diseases, but applied them to the spread of homicide in Newark, N.J., over a 26-year span from 1982 to 2008. And just as in other epidemics, certain neighborhoods…
Scientists have discovered for the first time how humans — and other mammals — have evolved to have intelligence. Researchers have identified the moment in history when the genes that enabled us to think and reason evolved. This point, 500 million years ago, provided our ability to learn complex skills, analyze situations and have flexibility…
As food allergies become increasingly common, a new study offers the first proof that they may be linked to pesticides found in tap water. Researchers at the American College of Allergy, Asthma and Immunology used existing government data to see whether people with more dichlorophenols in their urine were more likely to have food allergies….
Caltech physicist Sean Carroll makes the search for the Higgs boson a scientific detective story. At heart is the mystery of the universe.
The robotic equivalent of a Swiss army knife
Reconfigurable robot a step toward something that can become almost anything.
The reluctance of industrialized countries to accept binding emission targets will dry up demand for carbon credits and reduce their prices further, experts said at the climate talks in Doha, where 200 countries are trying to negotiate an agreement on climate issues. Russia, Japan, New Zealand have made it clear that they will not accept…
Two major organizations released climate change reports this month warning of doom and gloom if we stick to our current course and fail to take more aggressive measures. A World Bank report imagines a world 4 degrees warmer, the temperature predicted by century’s end barring changes, and says it aims to shock people into action…
This is not good news. A new international study—done by 47 experts using data from multiple satellites and aircraft—shows that the Earth is losing ice at an ever-increasing rate from both poles. We’ve known for years that the Arctic has been suffering massive ice loss, with the record low broken more than once in recent…
A group of neuroscientists and software engineers at the University of Waterloo in Canada are claiming to have built the world’s most complex, large-scale model simulation of the human brain. The simulated brain, which runs on a supercomputer, has a digital eye which it uses for visual input, a robotic arm that it uses to…
