Shark attack worries? Driving to the beach is more deadly

...ark attack does occur, it makes big headlines. The drive you will make to the beach is far more dangerous, but an auto accident that kills several people will not make big headlines across the U.S. But a shark attack on one person will." According to the International Shark Attack File, only seven fatalit...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...erg has led an effort to understand the genes that drive evolution, an innovative way of thinking because s...ntify the molecules that human cancer cells use to drive evolution, they can find ways of intervening and preventing the evolution of chemotherapy resistance...

Harmful chemicals may reprogram gene response to estrogen

...realized that the DES exposure enabled estrogen to drive the tumor development when combined with a genetic predisposition." While DES exposure can lead to the development of vaginal and cervical cancers, the fact that most DES-exposed women did not develop the cancers suggests that genetic predisposition...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

...c love is possibly a developed form of a mammalian drive to pursue preferred mates, and that it has an impo..., murder/suicide, demonstrate strength of romantic drive For instance, Fisher point out, "If someone rejects your sexual overtures, you don't harm yourself ...

Cricket's finicky mating behavior boosts biodiversity

...Changes in these preferences and choices appear to drive speciation. "That raises the question: Can something seemingly so individual as a choice have macro-evolutionary consequences in terms of increasing biodiversity? If so, this affects how life on the planet looks. The more species you have, the more ...

Supercomputer Dedicated To Bioengineering, Computational Biology Installed

...s of computational biology, but McCulloch said the drive to build ever faster and more specialized supercomputers has required computational biologists to continually reinvent their modeling software. "It's not new that science has been developing large computational challenges, but what is new is the comm...

Scientists discover how fish evolved to float at different sea depths

...even at high oxygen concentrations. These systems drive oxygen from the blood into the swimbladder allowing the fish to float at different levels in the sea without coming to the surface of the water for air. A similar system is also present in the eye of the fish, which provides oxygen to the retina. Dr...

Scientists discover that host cell lipids facilitate bacterial movement

...the bacterium. "As these filaments lengthen, they drive the bacterium through the cell until it reaches the peripheral or outer cell membrane," explains Dr. Frederick Southwick of the University of Florida College of Medicine. "Here the growing actin filaments push the bacterium against the membrane, form...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

... cause human diseases. Studying how such mutations drive development astray may lead to better understanding not only of these diseases, which are likely to be rare, but also of normal human development. ...

X-Ray Beams And Fruit Fly 'Flight Simulator' Aid Scientists' View Of Muscle Power

...e powerful muscles as they lengthen and shorten to drive the wings back and forth 200 times each second. “At the molecular level, the insect’s flight muscle and a human heart are remarkably similar,?Maughan said. “We biologists have always been amazed by how hard these muscles work. Now we have taken adva...

NJIT Presidential Award winner takes stem cell research another step

...the patient's bone would begin to heal. Arinzeh's drive to advance the science of stem cell research has gained her national recognition. In the fall, she earned the highest honor given to a young researcher by President Bush: The Presidential Early Career Award for Scientists and Engineers. What is it a...

Newly Discovered Compound Blocks Known Cancer-Causing Protein

...w drug that inhibits destructive cell signals that drive the growth of one-third of all cancers. The scientists showed they could block the growth of cultured colon cancer cells using this new compound, called cysmethynil. Their finding, reported in the March 22, 2005, issue of Proceedings of the National...
