HHMI researchers Richard Axel and Linda Buck win 2004 Nobel Prize

...ns criss-cross the cell surface seven times, which gives them a characteristic, snake-like shape. They also function in similar ways, by interacting with G proteins to transmit signals to the cell's interior. Since many receptors of this type share certain DNA sequences, Buck designed probes that would rec...

How roots control plant shoots

... lutein in daffodil flowers and the substance that gives color and flavor to saffron, a spice from crocus flowers. Details of the Experiments In the study, the biologists discovered the BPS1 gene and then demonstrated that it is required to prevent a plant from constantly producing the carotenoid byprod...

Research out this week helps us understand basics of how neurons communicate

...ication between nerve cells, Dr. Harkins said. "It gives us a basic understanding of how something works. In some ways, the body is similar to a broken car. When something goes wrong, you can't fix it if you don't know how it works."...

U-M scientists see ubiquitin-modified proteins in living cells

...and an HHMI associate investigator. "Visualization gives us a direct connection to cellular processes that we could only study in test tubes or indirectly before." In a paper published online this week in the early edition of the Proceedings of the National Academy of Sciences, Kerppola and Deyu Fang, M...

Cells in retina found to behave like soap bubbles

...ional scale, the cell is the indivisible unit that gives shape to something larger and recognizable -- a butterfly, a maple tree, a human being. How is this amazing diversity of species created? "It is like designing the pieces of a jigsaw puzzle so that they fit together seamlessly," said Carthew. "Under...

New method identifies chromosome changes in malignant cells

...ticularly important for cancer research because it gives scientists a clearer idea of what is really going wrong in tumors and thus points to possible treatments. The researchers already used their system to identify previously unrecognized immune system genes that are deleted in breast cancer cells, sugge...

...nd, where the bat exhibits the least vibration and gives the ball maximum propulsion. Robert Collier of Dartmouth College ( Robert.d.collier@dartmouth.edu ) will present newly detailed studies on how the different kinds of vibrations in a baseball bat--from the "crack" to the "thunk"--can provide importan...

New study on smallpox in monkeys reveals tactics of a killer

...ubverts host defenses. Uncovering these mechanisms gives scientists targets for developing countermeasures to lessen or block the ability of the smallpox virus to cause disease. Experts believe that this new knowledge of how smallpox acts on cells could speed up development of smallpox countermeasures....

Touching research: How white blood cells navigate

...in partnership with the blood vessel lining, which gives the cells access to tissue, like a police officer who clears the way for other officers to pursue the target. The physical touching between the cells and the lining is crucial. "This is your first line of defense against disease," says Richard Waugh...

Channel protein converts vibrations to electrical signal

...cell is to measure the electrical response that it gives when you stimulate the cell," Corey said. By putting a microelectrode on the mouse hair cells, the scientists could directly measure the amount of current flowing through the channels. With lower levels of TRPA1, current flow was diminished. In zebra...

Award-winning INEEL probe to help safely monitor hazardous waste sites

...l accept a variety of probe sensors, each of which gives different information about underground conditions, such as types of gases trapped in the soil and how dampness changes over time. Since one installation will do the job where many were needed before, workers save time and money, Jones says. GEOPS al...

Laboratory test of evolutionary theory confirms importance of links between populations

...ber of questions, he said. "This laboratory system gives us a halfway ground between the mathematical models and natural populations. It allows us to test whether our assumptions are realistic, and that puts us in a better position to design experiments in natural populations," Thompson said. Forde has al...

A new culprit in depression?

...-M Mental Health Research Institute. "This finding gives us a new target and a new set of ideas for pursuing better treatment." Akil notes that the brains of bipolar people in the study did not show the decreased FGF gene activity. "This was all the more remarkable since both groups of individuals were se...

Promising new preventative treatment option for population of men at high risk of prostate cancer

...y of stopping prostate cancer before it starts and gives patients and doctors a chance to fight this pervasive disease." In a multi-center, double-blind study, 514 patients with high-grade PIN and no cancer, determined by pre-study biopsies, were randomized to placebo or toremifene 20 mg, 40 mg or ...

OHSU study: Bacterial switching mechanism key to survival

...hy is you have a very high-resolution picture that gives you a detailed view of the molecules that ultimately cause specific biological responses." The research team knew that infectious bacteria are highly resilient when hunting down and using other sources of carbon for energy when their staple supplies,...

UF scientist: 'Brain' in a dish acts as autopilot, living computer

... a rat's brain and cultured inside a glass dish -- gives scientists a unique real-time window into the brain at the cellular level. By watching the brain cells interact, scientists hope to understand what causes neural disorders such as epilepsy and to determine noninvasive ways to intervene. As living com...

Bug's-eye-view of urinary tract reveals E.coli infection genes

... "Knowing its gene expression profile essentially gives us a snapshot of what's happening inside the urinary tract, from the pathogen's point of view." The study was designed to compare gene expression levels for the CFT073 strain of E. coli as the bacteria grew in three different environments. The first...

Children's Hospital Boston geneticist awarded for research on muscular dystrophy

...entification of a single gene on chromosome 4 that gives people an exceptionally long life expectancy. The gene was found by studying centenarians (people aged 98 or older) and encodes microsomal transfer protein, or MTP, a protein involved in the metabolism of fats. Kunkel is now expanding on this work t...

UCSD biologists discover chemical important in guiding visual system development

...some sort of surgery--like cataract removals--that gives them sight for the first time," added Feller. The researchers speculated that adenosine's role in controlling spontaneous neural activity may also explain why mothers taking medication for epilepsy are twice as likely to have children with a se...
