Chemists create 'Superbowl' molecule; May lead to better health

...ially resulting in improved treatment outcomes and perhaps saving lives, the researchers say. The molecule also shows promise for a wide range of other applications, including the removal of environmental toxins and aiding in chemical purification procedures, the investigators say. Their study was published...

UCSB scientists probe sea floor venting to gain understanding of early life on Earth

Growth in the sea comes down to a struggle for iron

...rbon from the atmosphere to affect global climate, perhaps even contributing to the onset of ice ages. Martin died in 1993 just as tests of his ideas were getting underway, but scientists have embarked on a series of experiments in three major areas of the world's oceans. "The three areas are the Southern O...

Timing is everything: First step in protein building revealed

...If we can betterunderstand how the ribosome works, perhaps we can harness it to help usfix disease."Already, scientists knew that without eIF1, the ribosome can startreading the gene's RNA instructions at places other than a particularthree-block piece of RNA known as the "start codon." And excessiveamounts ...

Researchers Uncover Key Step In Manufacture of Memory Protein

...help us to better understand the learning process, perhaps leading to better treatments for disorders of learning and memory,?said Duane Alexander, M.D., Director of the National Institute of Child Health and Human Development. The research team was led by Y.Peng Loh Ph.D, of NICHD’s Section on Cellular Neu...

Gene therapy converts dead bone graft to new, living tissue

... tiny fractures begin to accumulate until finally, perhaps in 10 years, the implanted section collapses, and more drastic surgery becomes necessary." To make the transplanted bone more robust, Schwarz looked into the activity of the genes and proteins that govern its health. His team replaced sections of bo...

New Clues Add 40,000 Years to Age of Human Species

...show that each major layer deposited very rapidly, perhaps within a few thousand years or less. In the case of the Omo hominids, the researchers linked the isotopic ages to a brief period during which sediments entombed both sets of bones. Together, the various lines of evidence seem to constrain the dates...

Scientists reveal molecular secrets of the malaria parasite

...ight on how the mosquito and parasiteinteract, and perhaps will lead to new ways of controlling the parasitein the vector. * Hall and scientists in Leiden identified evidence ofan unusual method of gene regulation (called post transcriptionalregulation) at the transition between the vertebrate host and themo...

Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

...eau. Some computer reconstructions indicate it was perhaps twice as thick at the end of the last ice age, also called the Last Glacial Maximum. But evidence from an ice core extracted near Siple Dome from 1997-99, along with other calculations, indicates ice in that area has lost only 200 to 400 meters of i...

UCSD discovery may help extend life of natural pesticide

...nges are detected, switching to another pesticide, perhaps even another variety of Bt that works through a different mechanism, could prevent the resistance genes from becoming widespread." According to the researchers, prior work indicates that there are other receptors that also contribute to Bt resistanc...

The very unexpected life and death of a leukemic cell

...death machinery in CLL cells. This was a hint that perhaps the leukemia cells were not immortal, a hypothesis tested by Nicholas Chiorazzi and colleagues in a paper appearing online on February 10 in advance of publication in the March 1 print edition of the Journal of Clinical Investigation. This new study ...

Falling ants glide back to trunk to avoid dangers of forest floor

...ly will be eaten by predators. Yanoviak said that perhaps more important from the perspective of survival, the forests are flooded as much as half the year, so an ant falling into the water will most likely end up as fish food. "That's what I think is the major evolutionary driving mechanism behind the beh...

Chemists identify key gene in development of type 1 diabetes

... prediabetic people to achieve lasting protection, perhaps a lifetime. But such a drug would take years to develop and test, the researchers caution. Likewise, effective gene therapy against the disease may take many years to develop, they add. Besides prevention, ISO-1 also is being tested in animals to de...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

...than genetic variation, in animals in the wild and perhaps humans." The authors conclude that neonatal infection can create later problems by changing how well the body can respond to future immune challenges. Those changes affect how well memories are stored. The early alterationS may be to the basic archi...

Vampire bats keep out of trouble by running

US life expectancy about to decline, researchers say

...will have life-shortening effects in the future -- perhaps enough to offset any improvements in longevity from anticipated advances in biomedical technology. Researchers also believe the life-shortening effect of obesity could rise so rapidly in the United States -- from two to five years in the next 50 yea...

UCLA launches $20 million stem cell institute to investigate HIV, cancer and neurological disorders

Proposition 71, passed by 59 percent of California voters in November, will provide $3 billion for stem cell research. ...

Dead zone area in Gulf could be increasing, researchers say

"During January and February of this year, the flow of the Mississippi River was ...
