Determining The Fate Of Cells In The Human Body

...e) of Nature Genetics establishes a model that may take scientists closer to understanding how cells in the human body determine their own fate. Researchers, led by Anthony Firulli, Ph.D., associate professor of pediatrics and of medical and molecular genetics at the Indiana University School of Medicine...

Tsunami-damaged coral reefs should be left to recover naturally, say scientists

...ases, so as to allow natural recovery processes to take place. Coral reefs have been subject to natural di...ife. Communities that are rebuilding hotels should take advantage of reconstruction funds to make sure there is effective sewage treatment available. And if...

Climatologists discover deep-sea secret

... "although we don't know where global warming will take us, this could be a sign that the oceans are already adapting to the changes". ...

Mice brains shrink during winter, impairing some learning and memory

...ed for several days to determine how long it would take them to find the platform, and whether they remembered where the platform was from day to day. Results showed that mice that were kept in short days ?simulating winter ?took longer and swam farther before they found the hidden platform than did the ...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...e of genetic diversity. The Antarctic Census will take extensive samples from the deep abyssal plain on the sea floor, 4,500 to 5,500 meters below surface, research that holds huge promise for biologists. Says Dr. Ron O'Dor, Chief Scientist of the Census: "DNA research made possible through this project...

Chronic Sinus Infection Thought To Be Tissue Issue, Mayo Clinic Scientists Show It's Snot

...in the tissue. Therefore, scientists might need to take not only the tissue but also the mucus into account when trying to understand what causes chronic sinus infections and probably other airway diseases." The findings could significantly change the way chronic sinus infection is treated, according to ...

Major new UNC-based drinking water study suggests pregnancy fears may be overstated

...e latter findings suggest that we or others should take a closer look at individual and groups of chemicals that might have a negative effect on pregnancy," he said. "I don't want to downplay those findings and say they were perfectly reassuring because they were not. But overall -- on balance -- I'd say ...

Cancer drug slows poxvirus in mice

...the vaccine even in people who otherwise could not take it. Given for a short period, Gleevec theoretically could hamper the cell-to-cell spread of virus and allow the body's immune system to mount a successful defense, he explains. Experiments to test whether Gleevec might work against smallpox virus as ...

Malaria mechanism revealed

... he joined my lab as a graduate student, it didn't take long for me to convince him that this was a good project," says structural biologist Leemor Joshua-Tor of Cold Spring Harbor Laboratory, who led the research. A major pathway through which malaria parasites invade red blood cells is the binding of a...

Studies reveal how plague disables immune system, and how to exploit the process to make a vaccine

...ticular kind of bacteria," said Schneewind. It can take eight to 10 days for the B and T cells to multiply and fully engage. "By that time, with plague," he said, "the host is dead." The bacteria's Achilles heel, however, may be a protein called LcrV, which Y. pestis transports through the needle and use...

Immune system's distress signal tells bacteria when to strike back

...them know they need to find a new home. They don't take that news any better than we would." A vulnerable host, like a condemned home, is a liability, a threat to its tenants' survival. Pseudomonas, however, has the tools to engineer its own escape ?by killing off the host. This wily pathogen can evade ...

Random gene expression may drive HIV into hiding

...influence if and when these chemical modifications take place. Because of Tat's positive-feedback loop, "...rs," said Arkin. If the appropriate modifications take place, then the HIV genome is transcribed and the positive feedback loop kicks in. If these Tat modi...

MIT engineers an anti-cancer smart bomb

...y to tumors if you have destroyed the vessels that take it there," Sasisekharan said. Also, the two drugs behave differently and are delivered on different schedules: anti-angiogenics over a prolonged period and chemotherapy in cycles. "We designed the nanocell keeping these practical problems in mind," ...

Depression gene may weaken mood-regulating circuit

...moods and eventually depression as life's stresses take their toll. Other members of the NIMH team were: Dr. Lukas Pezawas, Dr. Bhaskar Kolachana, Dr. Michael Egan, Dr. Venakata Mattay, Emily Drabant, Beth Verchinski, and Karen Munoz. Dr. Ahmad Hariri, University of Pittsburgh, also participated in the s...

Proteomics brings researchers closer to understanding microbes that produce acid mine drainage

...ornia, Berkeley, researchers to probe the give and take in this microbial mat. Last year, the UC Berkeley team joined with the Department of Energy's Joint Genome Institute to pluck out the genomes of the five dominant bacteria in a slime, or biofilm, responsible for acidic drainage from the mine. Now, t...

UCR chemist part of team identifying new areas of gene regulation

...which are where most gene regulation is thought to take place. The team used mass spectrometry to show that acetylation at the core of the histone is associated with gene activation by attracting the protein string known as the SWI/SNI chromatin remodeling complex to the location of acetylation. "In this...

Where Bacteria Get Their Genes

...h which they exchange pieces of DNA. They can also take up genetic material from the environment. Ochman thinks the team's findings will stir new research in bacterial evolution. "It should be exciting to see whether gene transfer has been so widespread in other groups of bacteria, too." ### Emmanuelle...

New method shows it is possible to grow bone for grafts within a patient's body

... proven to be surprisingly simple. They decided to take advantage of the body's natural wound-healing response and create a special zone on the surface of a healthy bone in hopes that the body would respond by filling the space with new bone. The approach lived up to their highest expectations. Working wi...
