Yellowstone microbes fueled by hydrogen, according to U. of Colorado study

...ny organisms living in thermal features. "Itwas a surprise to find hydrogen was the main energy source for microbesin the hot springs," Pace said. "This project is also interesting inthe context of microbiology because it's one of the few times we'vebeen able to study microbes to get information on an entire...

An HIV Protein Plays a Surprising Role in Gene Activation

... turn required to activate transcription. The big surprise came in the next round of experiments, which explored Tat's influence on transcription and PIC assembly on the HIV promoter. As expected, transcription factors were “virtually undetectable?at the core promoter in the absence of Tat. Adding Tat recrui...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

...e tags turn genes on and off individually. The big surprise involves clusters of so-called "HOX" genes, which ...regions of the genome carry such tags. A complete surprise Most regions of the chromatin have only a few "on" tags, but in regions packaging clusters of HOX g...

New SARS Protein Linked To Important Cell Doorway

...virus does make the protein, but we also got a big surprise when we looked at where the protein was," says Diamond. "Based on our analysis of the genome, we thought the orf7a protein would be on the surface of infected cells, decoying the immune system in some obvious way. But we found that most orf7a protein...

Scientists discover that host cell lipids facilitate bacterial movement

... was taking place," recalls Dr. Southwick. "To our surprise these lipids also localized to the front of the moving bacteria." The researchers also noticed that Listeria movement slowed down when the bacteria were treated with molecules that inhibited PI3-kinase, proving that Listeria depend on PI3-kinase to m...

World's largest rainforest drying experiment completes first phase

... clearing and burning itself." First, the biggest surprise noted thus far has been the great tolerance that this forest presented in the face of the severe drought that was created. As the moisture stored in the soil that sustained the forest during prolonged dry seasons was depleted in the dry plot, the tre...

One gene links newborn neurons with those that die in diseases such as Alzheimer's

...ential medical implications of the study came as a surprise to the researchers. They set out to answer fundamental questions about the small number of brain neurons that can be replaced when they die: Are these cells similar to other neurons that are not replaced in adult life? Or, in terms of which genes are...

Finding hidden invaders in a Hawaiian rain forest

...est is undergoing." The scientists also had a big surprise using the new aircraft-based techniques: they located another invader, the Kahili ginger plant (Hedychium gardnerianum), growing under the forest canopy. Ginger cannot be detected from above the forest canopy using traditional aircraft or satellite a...

Disabling gene defuses rheumatoid arthritis in mice

...ined healthy even after the injections. "It was a surprise finding," Peng says. "We really didn't expect to see this kind of response." Further study revealed that neutrophils in the mice were killing themselves through a cellular self-destruct process known as apoptosis. Damaged or highly stressed cells ca...

Study of energy and health in Africa focuses spotlight on charcoal and forest management

... while it becomes charcoal," Kammen said. "It's no surprise it's not generally a high-efficiency operation." The authors found that by creating the technological and policy tools for transitioning to higher efficiency charcoal production technologies and sustainable harvesting, like those used today in count...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

...versity of North Carolina at Chapel Hill got a big surprise while investigating how plants respond to attacks from disease organisms such as bacteria and viruses. "Contrary to what we thought we'd find, our experiments showed that at least three different proteins work in concert with one another in tug-of w...

FDA approves more generic AIDS drugs

Discovery of an American salamander where it shouldn't be: Korea

... University of California, Berkeley, an equivalent surprise was the recent discovery in Korea of a type of salamander that comprises the majority of species in the world, but is totally unknown in Asia and rare outside the Americas. "I've discovered and named nearly 50 species of salamanders - more than 10 p...

Scientists focus on 'dwarf eye'

...ng nanophthalmos. According to Sundin, MFRP was a surprise candidate. "Mutant MFRP was recently identified in mice as a cause of retinal degeneration, not extreme farsightedness," he said. "However, a mouse's eyes do not adjust their focus through growth like human eyes do, so MFRP has a completely diffe...

Secrets to antibody's success against West Nile Virus surprise scientists

...s process at a later point. "This was a complete surprise to us, but it gives us some very useful insights," says senior author Daved Fremont, Ph.D., associate professor of pathology & immunology and of biochemistry & molecular biophysics at Washington University School of Medicine in St. Louis. "Ba...

One bacteria stops another on contact

...cteria that they touch. The finding was a complete surprise to the scientists, said Low. The discovery may eventually lead to new antimicrobial agents to halt bacterial growth which would be an entirely new system to shut bacteria down, according to the scientists. "This has potential implications for new a...

Naturally occurring asbestos linked to lung cancer

...tos in an industrial setting. It would have been a surprise to find otherwise." Similarly, she said, it was no real surprise to scientists when passive smoking was found to cause lung cancer. "Like smoking, exposure to asbest...

Geckos: It's not always about sex

...the treadmill," said Kearney. "This was a bit of a surprise because a similar study of another kind of parthenogenetic lizard from the deserts of the United States showed the opposite pattern." Added Autumn: "If there was an Olympic team of Bynoe's geckos, there wouldn't be a single male on it. These geckos ...

Living with salt

...presence of salt, though not dependent on it. In a surprise twist, the researchers discovered that one other known carbonic anhydrase - found in mouse kidney - sported a similar, salt-tolerant construction. Pondering why a structure conferring salt tolerance should evolve once in a Dead Sea organism and once ...

'Underground' tunnels discovered as means for communication between immune system cells

... recalled of that moment, when to both their great surprise the researchers witnessed how that little mishap had caused the macrophages to release bursts of calcium. Returning to dendritic cells, they found that by giving a deliberate poke with an empty microinjection tip it caused the same reaction. But why...
