Jan. 8, 2013: In the galactic scheme of things, the Sun is a remarkably constant star. While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our own sun varies a measly 0.1% over the course of the 11-year solar cycle.
There is, however, a dawning realization among researchers that even these apparently tiny variations can have a significant effect on terrestrial [...]

Helium is also used in medical scanners and particle colliders
Supplies could run out in 30 years, says NRC
Helium serves a vital purpose for research scientists – but some are now warning that their experiments are at risk from a shortage of the gas, because stocks are being wasted on party balloons.
Last week researcher Oleg Kirichek had to postpone an experiment at the Rutherford Appleton Laboratory in Didcot when helium stocks [...]

There is so much junk in space that collisions could start to increase exponentially, leading to a continuously growing pile of rubble in orbit, a new report warns.
The independent report, released today (Sept. 1), surveyed NASA’s work to meet the threat [...]

THE Deepwater Horizon blowout is the largest oil spill in US history, but its ecological impact need not be the worst. It all hinges on the amount and composition of the oil that reaches the Gulf of Mexico’s most sensitive habitat: its coastal marshes. If they can be protected, the region could bounce back in just a [...]
