How to eliminate motion sickness on tilting trains

Scientists have found that motion sickness on tilting trains can be essentially eliminated by adjusting the timing of when the cars tilt as they enter and leave the curves. They found that when the cars tilt just at the beginning of the curves instead of while they are making the turns, there was no motion...

Better desalination technology key to solving world's water shortage

Over one-third of the world's population already lives in areas struggling to keep up with the demand for fresh water. By 2025, that number will nearly double. A new Yale University study argues that seawater desalination should play an important role in helping combat worldwide fresh water shortages -- once conservation, reuse and other methods have been exhausted -- and provides insight into how...

East Africa's climate under the spell of El Niño since the last Ice Age

The current severe drought in East Africa is being attributed to La Niña conditions that prevailed in the Pacific until May 2011. The waxing and waning of rainfall in eastern tropical Africa in unison with El Niño-Southern Oscillation is not unusual and existed already 20,000 years ago, though the region's last 3,000 years have seen a less stable climate, according to a study published by an...

Elusive gene mutations found for malignant brain tumor

A discovery by scientists at Duke University Medical Center and Johns Hopkins University could increase the chances for an effective combination of drug therapy to treat the second most common type of brain tumor. For years scientists have been looking for the primary cancer genes involved in the development of oligodendrogliomas. Scientists knew the two chromosomes that held the probable...

Engineers solve longstanding problem in photonic chip technology: Findings help pave way for next generation of computer chips

Stretching for thousands of miles beneath oceans, optical fibers now connect every continent except for Antarctica. But although optical fibers are increasingly replacing copper wires, carrying information via photons instead of electrons, today's computer technology still relies on electronic chips. Now, researchers are paving the way for the next generation of computer-chip technology: photonic...

Screening effort turns up multiple potential anti-malaria compounds; Possible resistance-proof drug pairs found

Numerous potential anti-malarial candidate drugs have been uncovered by researchers. Researchers used robotic, ultra-high-throughput screening technology to test more than 2,800 chemical compounds for activity against 61 genetically diverse strains of lab-grown malaria parasites. They found 32 compounds that were highly effective at killing at least 45 of the 61...

Breakthrough in photonic chip research paves way for ultrafast information sharing

Researchers have discovered a way to prevent light signals on a silicon chip from reflecting backwards and interfering with its operation. Otherwise, the light beams would interfere with lasers and other photonic components on the chip and make the chip unstable. The breakthrough marks a significant achievement in the development of integrated photonic chips that could replace electronic chips as...

Briny water may be at work in seasonal flows on Mars

Dark, narrow features running down slopes in the warmer regions of Mars point to the possibility of salty water as the causing agent. Never observed before and strongly associated with the warmer seasons on Mars, the features show growth, suggesting they may form near the surface today in rare times and places.Never observed before and strongly associated with the warmer seasons on Mars, the...

'Miracle Turtle' Released as Crowds Cheer

A badly injured sea turtle that underwent a year of rehabilitation and innovative surgeries was released Wednesday by caretakers hoping he finds a mate and helps his endangered species prosper. Andre, as the 177-pound green sea turtle is known, crawled into the water and swam out of sight before a crowd of hundreds of raucous supporters. He was near death when he was found split open and...
