NASA satellites have captured striking images of vast palls of smoke billowing from wildfires on the Indonesian island of Sumatra. The smoke has been moving east and has descended on Malaysia and Singapore, pushing air pollution to record levels. Singapore’s yardstick of pollution, the Pollutant Standards Index (similar to the U.S. Air Quality Index) peaked […]

Greening of Arctic will be dramatic, say scientists
New computer models based on observations of plant growth in the Arctic suggest that rising temperatures will lead to a massive increase in plant and tree cover over the next few decades. The research, appearing in Nature Climate Change, suggests that wooded areas in the Arctic could increase by as much as 50 percent. “Such […]
Rethink E.T. Message Detection Says Prof
E.T. might be better off writing than phoning, according to Christopher Rose at Rutgers University. Rose says that inscribing information and physically sending it to a location in space is more energy-efficient than sending it out on radio waves. “Think of a flashlight beam,” Rose says. “Its intensity decreases as it gets farther from its […]
Superfast Evolutionary Change In Mice Observed
A study of a common wild mouse by two University of Illinois at Chicago biologists has found evidence of dramatic evolutionary change in a span of just 150 years, suggesting genetic evolution can occur a lot faster than many had thought possible. The findings are the first report of such quick evolution in a mammal […]
