What would it look like to approach an asteroid in a spaceship? In 2010, ESA's robotic Rosetta spacecraft zipped past the asteroid 21 Lutetia taking data and snapping images in an effort to better determine the history of the asteroid and the origin of its unusual colors.
'Huge' water resource exists under Africa
Scientists say the notoriously dry continent of Africa is sitting on a vast reservoir of groundwater.
They argue that the total volume of water in aquifers underground is 100 times the amount found on the surface.
The team have produced the most detailed map yet of the scale and potential of this hidden resource.
Google execs, director Cameron in space venture
Unobtainium, anyone?
Google executive chairman Eric Schmidt and billionaire co-founder Larry Page have teamed up with "Avatar" director James Cameron and other investors to back an ambitious space exploration and natural resources venture, details of which will be unveiled next week.
The fledgling company, called Planetary Resources, will be unveiled at a Tuesday news conference at the Museum of Flight in Seattle, according to a press release issued this week.
Aside from naming some of the company's high-profile backers, the press release disclosed tantalizingly few details, saying only that the company will combine the sectors of "space exploration and natural resources" in a venture that could add "trillions of dollars to the global GDP." The Wall Street Journal reported Friday that Planetary Resources will explore the feasibility of mining natural resources from asteroids, a decades-old concept.
IBM creates breathing, high-density, light-weight lithium-air battery
Therein lies the crux of IBM’s Battery 500 project: Current battery tech simply cannot come close to gasoline, which is why we’re surrounded by electric cars that are lumbered down by massive batteries that can only go 100 miles — and why gas still rules supreme. Eventually (in another 10 years or so), li-ion batteries could be replaced with li-air batteries that are a tenth of the size and weight, and yet last just as long — or, of course, li-air could replace gasoline.
Neonicotinoid Pesticide Reduces Bumble Bee Colony Growth and Queen Production
Treated colonies had a significantly reduced growth rate and suffered an 85% reduction in production of new queens compared with control colonies. Given the scale of use of neonicotinoids, we suggest that they may be having a considerable negative impact on wild bumble bee populations across the developed world.
Synthetic Genetic Polymers Capable of Heredity and Evolution
Thus, heredity and evolution, two hallmarks of life, are not limited to DNA and RNA but are likely to be emergent properties of polymers capable of information storage.
