National Science Foundation awards research grant for $1.1 million to UA Museum

...esearchers use these specimens to study changes in things like stable isotope ratios, emergingpathogens, population distribution and genetics. The samples collected today can last for several centuriesand be used to answer the questions of tomorrow, museum researchers said. "These specimens are used to esta...

UNC opens first clinical trial of vaccine treatment for advanced breast cancer

...he researcher said. "This is how we envision doing things in the next millennium." As to the vaccine's future, the UNC team hopes it will see more widespread use. "We're hoping that if it shows some benefit against metastatic disease that the vaccine treatment will eventually be used earlier, for instance...

What makes cells tick detailed by Dartmouth researchers

...cists have clarified the picture of the way living things maintain robust and stable internal clocks to safeguard the timing of daily activities. Internal clocks are ubiquitous. In humans they cue circadian rhythms, the 24-hour cycle that paces life's ebb and flow, from when we wake up to when we go to sl...

Gene discovered for primary pulmonary hypertension

...d their development can be associated with several things including: pregnancy, hypothyroidism, and the use of oral contraceptives, cocaine, or the appetite suppressant drugs, phentermine-fenfluramine (phen-fen). Phen-fen is no longer available in combination due to these effects. People with autoimmune d...

... destruction of ecosystems. But there are a lot of things people value that can't readily be expressed in dollar terms. We need to use other metrics, and to move cautiously." Daily and her fellow authors concede that coming up with a universally acceptable method for evaluating nature will be a challenge. "...

Pigs at sea reveal latest clues in homicide research

...significant promise. "We're seeing a wide range of things happening in the underwater environment, " says Anderson, who relies on divers to record activity and collect species for later analysis. During a recent site visit, Coast Guard divers found the sunken carcasses re-floating. Anderson had expected ...

Cincinnati researchers document environmental problems caused by tourist trade in Crete

...d its spectacular beauty, they're one of the first things in nature to show signs of distress when the environment is under strain. That's why Frank Wray, a University of Cincinnatibiologist, grew alarmed when he returned for hissecond summer field project in Hersonissos, Crete, as a member of the UC Susta...

Giant jellies invade Gulf of Mexico threatening shrimp fishery

...ght inches in diameter," says Perry. "Some of the things we investigating are how widespread the invasion is, what their feeding habits are, how much they eat, and whether they can survive over the winter months in the Gulf waters." Whether they can survive and become a new permanent resident to the nort...

UCSF researchers identify regulator of critical brain messenger, hinting at therapy

... long time," says Edwards. "It is one of the final things that will enable us to study the basic function of how synapses work." The finding's importance resembles that of the discovery of glutamate receptors, the proteins that respond to glutamate on target cells, says Edwards. "Our finding represents the ...

New HIV model

...en the HIV virus binds to a CD4 cell, one of three things can happen, according to Kirschner. First, the cell can be actively infected and turn into a cellular factory that produces more virus. Second, the immune cell can be latently infected; the virus gets inside the cell nucleus, but remains dormant. ...

Review article highlights tiny motors driving cell division

Living things grow and thrive because their cells -- the tiny building blocks of muscle, skin, branch and flower -- are constantly duplicating themselves. In that process, gene-bearing chromosomes inside each cell must separate into identical sets to form two daug...

Warming trend seen in late freeze, early thaw of northern waterways, say Science researchers

...e behind this rise in variability. "One of the things that we are beginning to do with these types of data is to separate out the effects of different climate signals, like El Nio. We are optimistic that these long and geographically widespread ice cover records can play some role in sorting out the eff...

Beyond the French paradox

...ol's apparent reduction of CHD risk. "One of the things that alcohol may do is alter the balance of something called 'cytokines,'" he said. "Cytokines are hormone-like proteins, biological substances that almost all cells make, particularly blood cells. I think that alcohol may alter the balance of c...

Massive new research effort will map inner workings of cells - San Francisco VA Medical Center chosen to host core laboratory

...th different types of expertise, we can accomplish things that would be impossible for even a very large single lab," said Seaman, chief of immunology at the San Francisco VA Medical Center and UCSF professor of medicine and microbiology. And unlike most research projects, scientists in the Alliance will pu...

They decided to turn things around, using the electron gun to flood the sample with low energy electrons, thus negatively charging the surface and causing controlled, easily detectable changes in the energy of the ejected photoelectrons. By measuring these changes, the research...

Tiny microchips have big promise in fighting serious diseases

...opic chips will let us do a whole host of exciting things in biomedicine," said Robert Michler, chief of cardiothoracic surgery at Ohio State University. Michler and several colleagues discussed the role nanotechnology may play in medicine of the future during a presentation Sept. 26 in Columbus at the BioM...

Prions may play crucial role in evolution.

...ght be stopped. But the real puzzle is why these things exist in yeast cells in the first place. University of Chicago researchers appear to have found the answer, and it has broad and unexpected implications: the yeast prion seems to play an adaptive role and may greatly influence evolutionary processes....

Gene alterations for cystic fibrosis may also account for chronic sinus problems in some

"But we wondered if at least some sinusitis sufferers in the general population might also carry a variant of one copy of the CFTR gene...

Hopkins scientists shed light on how the brain 'thinks'

...gramming the robot, we can produce the dynamics of things that either exist naturally or don't make sense. We simulate the dynamics of systems and we look at how people learn to control those systems," he says. Behind the experiments is a concept called "primitives," the abstract elements by which the brain...
