NASA, GM Take Giant Leap in Robotic Technology

Robonaut2 -- or R2 for short -- is the next generation dexterous robot, developed through a Space Act Agreement by NASA and General Motors. It is faster, more dexterous and more technologically advanced than its predecessors and able to use its hands to do work beyond the scope of previously introduced humanoid robots. (Credit: NASA)

From Science Daily:

ScienceDaily (Feb. 7, 2010) — Robonaut is evolving.

NASA and General Motors are working together to accelerate development of the next generation of robots and related technologies for use in the automotive and aerospace industries.

Engineers and scientists from NASA and GM worked together through a Space Act Agreement at the agency's Johnson Space Center in Houston to build a new humanoid robot capable of working side by side with people. Using leading edge control, sensor and vision technologies, future robots could assist astronauts during hazardous space missions and help GM build safer cars and plants.

How Sperm Swim: A Clue For Male Contraception?

Photo: 3D4Medical.com/Getty

From Time Magazine:

Though sperm are generally considered pretty wriggly little guys, before they are launched into action, so to speak, they aren't racing around. While researchers have long known that what gets them swimming is a change in internal pH level—the more alkaline their pH, the more aggressively they swim—until now, the mechanism by which sperm rapidly drop protons, which changes their pH from acidic to alkaline, wasn't clear. According to this new study, published in the journal Cell, sperm are equipped with tons of tiny little pores that, when open, enable them to release protons and get a move on.

Top British Scientist Says UN Panel Is Losing Credibility

From Times Online:

A LEADING British government scientist has warned the United Nations’ climate panel to tackle its blunders or lose all credibility.

Robert Watson, chief scientist at Defra, the environment ministry, who chaired the Intergovernmental Panel on Climate Change (IPCC) from 1997 to 2002, was speaking after more potential inaccuracies emerged in the IPCC’s 2007 benchmark report on global warming.

The most important is a claim that global warming could cut rain-fed north African crop production by up to 50% by 2020, a remarkably short time for such a dramatic change. The claim has been quoted in speeches by Rajendra Pachauri, the IPCC chairman, and by Ban Ki-moon, the UN secretary-general.

GOOD news surfers: waves in the north-east Pacific are getting taller, and the height of the most extreme "100-year" waves is increasing fastest.

Previous data had shown wave height to be increasing in the north-east Pacific and north Atlantic since the late 1980s. Now measurements from a deep-water buoy moored off the Oregon coast since the mid-1970s indicate that the "100-year" waves - the monster waves with a 1 per cent chance of occurring in any given year - could be 40 per cent larger than previous estimates, at 14 metres high.

Computers That Use Light Instead of Electricity? First Germanium Laser Created

From Science Daily:

ScienceDaily (Feb. 5, 2010) — MIT researchers have demonstrated the first laser built from germanium that can produce wavelengths of light useful for optical communication. It's also the first germanium laser to operate at room temperature. Unlike the materials typically used in lasers, germanium is easy to incorporate into existing processes for manufacturing silicon chips. So the result could prove an important step toward computers that move data -- and maybe even perform calculations -- using light instead of electricity. But more fundamentally, the researchers have shown that, contrary to prior belief, a class of materials called indirect-band-gap semiconductors can yield practical lasers.

Genes Help Explain Who Gets Fit

From Live Science:

When you put in hours at the gym, you expect to get fitter. It turns out, that assumption doesn't hold true for everyone. A new study suggests specific genes may determine, at least in part, how much we really benefit from exercise.

While "benefit from exercise" can mean plenty of things, from slimming down to boosting one's ability to complete a marathon, the researchers specifically looked at what is called VO2 max, or aerobic capacity. This is a measure of how much blood your heart pumps and how much oxygen your muscles consume when they constrict to, say, move your legs on a treadmill.

The Big Question: What Do We Know About The Human Brain And The Way It Functions?

Independent Graphics

From The Independent:

Why are we asking this now?

Scientists this week announced that they had succeeded in communicating with a man thought to be in a vegetative state, lacking all awareness, for five years following a road accident. Using a brain scanner they were able to read his thoughts and obtain yes or no answers to questions. They asked him to imagine playing tennis if he wanted to answer yes and to imagine walking through his home if he wanted to say no. By mapping the different parts of the brain activated in each case with the scanner, the scientists were able accurately record his reponses.

The results suggest that, even with their tiny brains, insects can handle image analysis. The researchers say that if humans want to design automatic facial recognition systems, we could learn a lot by using the bees' approach to face recognition.
