Brainstem blocks pain to protect key behaviors

...t of oxygen deprivation. Fields suspects that the link between eating and pain relief, in a society where the risks of caloric plenty far exceeds those of predation, may even be related to obesity. "Are OFF cells promoting bravery," he asked, "or gluttony?" ...

Telling axons where to go - and grow

...ly closes this circle of regulation, providing the link between actin dynamics, axonal growth and Rnf6. Importantly, the authors are able to show that changes in axon outgrowth induced by changes in levels of Rnf6 can be restored by compensatory changes in LIMK1 expression, thereby giving Rnf6 a central ...

ORNL leading effort to help harness power of Shewanella

...the many individual research domains and projects, link to analysis applications, visualize data in a cell systems context and produce new knowledge. This will be accomplished while minimizing the effort, time and complexity to participating laboratories, Uberbacher said. This effort could have a dramati...

Johns Hopkins flu expert calls for mandatory vaccination of health care workers

... they call in sick so it is difficult to precisely link seasonal hospital absenteeism and high rates of non-vaccination, she notes. "We need to close the very serious gap between knowledge and behavior that exists among health care workers," Perl argues, and it can be done, she says. In 2003, her team, ...

No link found between caffeine intake and development of hypertension in women

...sion in women," the authors write. Concerning the link found between colas and hypertension, the researchers write: "? we speculate that it is not caffeine but perhaps some other compound contained in soda-type soft drinks that may be responsible for the increased risk in hypertension. If these associati...

New, unique microscope for nanotech

...scent tags to look at structures inside a cell and link them to very small changes on the cell membrane. Materials scientists could use it to get information about the bulk structure of a material and to measure the arrangement of atoms at the surface. The tip of the atomic force microscope can also be us...

'Computer-chemistry' yields new insight into a puzzle of cell division

...tions occur --on the phosphatase and the kinase to link precisely, Rudolph said. The two molecules' component parts, or "residues," must also orient in a tongue-and-groove fit at a few other special places, which the researchers dubbed 'hot spots," on the irregular molecular surfaces. Only when active si...

Setting the standard for computer models of life

...eated it, whether it's been modified, and a stable link to its full description; the second scheme links the components of the model to relevant bioinformatics resources: for example, a model of alcohol metabolism in the liver would be annotated with links to the protein databases for all the enzymes invo...

UCSD study finds anthrax toxins also harmful to fruit flies

...es, show that fruit flies can be used to study the link between the biochemical activities and physiological effects of anthrax toxins. Learning how these toxins attack developing and adult tissues is important because it can help scientists understand how they function at the molecular level and may lea...

Bones from blood: Scientists aim to break new ground on fractures

... Unit (SATSU) in the Department of Sociology, will link the scientific questions of MSC isolation and expansion to the wider environment and define potential barriers and areas of weakness in their use. They will consider questions such as safety and standards, commercial viability, potential investment, ...

Environmental tobacco smoke linked to behavior problems in children and pre-teens

...ording to Dr. Yolton. Previous studies have found link between tobacco smoke and birth weight, number of infections and other health problems, including asthma exacerbations. In a groundbreaking study in 2002, Dr. Yolton found that exposure to environmental tobacco smoke, even at extremely low levels, i...

'Virus chip' detects new virus in prostate tumors

...ce, has never been detected in humans. The virus's link to human disease is still unclear, and more study is needed to determine the relationship between the virus and cancer, if any, the scientists say. The discovery was made with the same DNA-hunting "virus chip" used to confirm the identity of the S...

UF scientists reveal ancient origin of vertebrate skeleton

...ure for the past 100 years that has been argued to link all vertebrates, to the exclusion of lampreys and hagfishes, is bone, pure and simple," Caldwell said. "It is the lack of bone in these animals and the supposed uniqueness of their cartilage, that has for so long plagued scientists in their attempts ...

UC Berkeley researchers create a biologically-inspired artificial compound eye

...gital cameras and camcorders. He also has plans to link them to spectroscopes for chemical detection and analysis. "The lenses and waveguides are the most important part of the system," Lee said. "People have said that it would be totally impossible to create them with an angle, but now that we've done i...

Powerful new tool for studying brain development

...amounts of biological information. "Our ability to link images of gene expression patterns to information on those genes in other databases increases the value of each new gene discovery," Mehta said. This integration of multiple research approaches and information provided by the BGEM was key to the suc...

Researchers reverse juvenile diabetes in animal model

Researchers get neurons and silicon talking

... simple adhesive, however. "They also provided the link between ionic channels of the neurons and semiconductor material in a way that neural electrical signals could be passed to the silicon chip," says Vassanelli. Once there, that signal can be recorded using the chip's transistors. What's more, the ne...

A link is found between morphine addiction and the tendency to explore

There's something fishy about human brain evolution

...ists are ignorant or dismissive of the key missing link to help answer this question: the metabolic constraints that are critical for healthy human brain development today, and for its evolution. Human brains aren't just comparatively big, they're hungry. The average newborn's brain consumes an amazing 7...
