Robots that act like rats

... in Schank's laboratory,they move about until they hit a wall, feel their way along the walluntil their nose goes into a corner, then mostly stay put. Becausetheir senses and responses are so limited, pups should be a goodstarting point for building robots that can do the same thing. Joshi's laboratory b...

X-rays have become laser-like

...ionth of a second (= 5 femtoseconds). These pulses hit the atoms so abruptly that they have no time to disintegrate before emitting the X-ray burst. Thanks to this extremely short interaction time, the researchers have not only managed to break the nanometer barrier but also created a source of X-ray bur...

Survivors to revisit the polio scare

... older children and adults, and disproportionately hit the middle class. Scientists now believe that improved sanitation was to blame. When water supplies were consistently contaminated with the poliovirus, as they were in impoverished areas, people were typically infected during infancy -- but most suff...

Researchers go into action after Tsunami

...t we found was quite unexpected. Even in the worst hit areas, many well engineered buildings suffered only modest structural damage, however they offered little protection from the tsunami. This is the opposite to what we find for normal earthquakes and has major implications for coastal communities worl...

Ebola virus: from wildlife to dogs

... of the people infected. Seven such outbreaks have hit Gabon and the Republic of Congo since 1994, leading to 445 cases resulting in 361 deaths. Ebola virus thus constitutes a grave public health problem in these countries. No medicine or vaccine is currently available, only prevention and rapid control ...

That would be a substantial hit affecting basic research grants such as those funded under the University Research Initiatives program and the Defense Research Sciences program. Advocates have argued that science and technology funding should account for at least 3 percent of the d...

University of Pittsburgh gets wired for speed with Apple Xserve G5 cluster

...RGH, April 13 Every week in the CBS network's new hit series Numb3rs, an FBI agent relies on his math genius brother to find patterns and equations that help to solve crimes. With its new Apple Xserve G5 computing cluster, the University of Pittsburgh's Graduate School of Public Health (GSPH) is solving...

Low oxygen likely made 'Great Dying' worse, greatly delayed recovery

...ey said. He calculated that when the oxygen level hit 16 percent, breathing at sea level would have been like trying to breathe at the summit of a 9,200-foot mountain today. By the early Triassic period, sea-level oxygen content of less than 12 percent would have been the same as it is today in the thin...

Researchers make gains in understanding antibiotic resistance

...es to avoid the effects of one drug, it still gets hit by another. However, in the case of these antibiotics, the binding sites are linked in one molecule. It's like a multi-drug treatment, but in one compound," he said....

New tool reveals secrets of migrating cells

... The idea behind two-photon imaging is that if you hit a dye molecule in a short period of time with two photons of light, each photon half the energy needed to excite it, the dye can absorb them together and then fluoresce. The less energetic, long-wavelength photons will go deeper into the tissue, caus...

Research takes big picture of wheat streak mosaic

The mites migrate from thevolunteer wheat to the early wheat planted for grazing, he said. "That's where we have a...

Slow balls take the swing out of young ball players

The new tuberculosis vaccine, a live recombinant vaccine named rBCG30, was developed in the course of research at UCLA's David Geffen School of Medicine by Dr. Marcus Horwitz and his team. The rBCG30 vaccine overexpresses the major...

Keeping cancer in check

...et of biochemical steps. For example, if a cell is hit by radiation, enzymes called kinases activate p53, leading to inhibition of cell replication. "We found that cells without p53 due to a mutation would continue to proliferate under low glucose conditions, bypassing the AMPK checkpoint," says Jones. T...

Killer dinosaurs turned vegetarian

But in order for these exciting technologies to hit the marketplace (who wouldn't want an itty-bitty robot), scientists must understand how these miracle-molecules perform under all sorts of conditions. For, without nanoscience, there would be no nanotechnology. In a recent study, researchers at the ...

Researchers find gene that may be at root of potato blight
