Confirmation of human protein interaction data by human expression data

...ave those losing neurons a fighting chance through another molecular twist. She managed to silence some neurons near the green, quietly-firing cells. When she did that, the green cells were able to compete successfully and formed longer, more complex arbors. Although this work specifically examined the brai...

Poaching, logging, and outbreaks of Ebola threaten central African gorillas and chimpanzees

...the Wildlife Conservation Society's Congo Program, another author of the action plan. "It will take a tremendous amount of work and dedication from a variety of conservation groups, government agencies and donors, but we still have a chance to save these animals." The Brazzaville meeting was organize...

Deep thinking: Scientists sequence a cold-loving marine microbe

... psychrerythraea's genome will yield insights into another cool character, its namesake. Deming, who led the establishment of the Colwellia genus, named the genus after her one-time advisor: noted marine biologist Rita Colwell. In addition the TIGR team, led by Methé, study collaborators include: Jody Demin...

A whole lot of shaking goin' on triggers early hatching in red-eyed tree frogs

... to wiggle frantically. As the snake moves to take another morsel, the embryos rupture their egg capsules, dr...haken by a hungry reptile but not when buffeted by another outside force such as rain, is a question that has now been answered in part by Boston University re...

Brown-Harvard team solves mobile DNA's surgical sleight-of-hand

...nation, DNA can travel inside an organism, or into another organism, and perform a sort of grafting surgery that allows it to insert its chromosome into a chromosome of the target cell. The process is important because mobile DNA can carry genes that cause drug resistance or transmit viruses that cause disea...

Motor transport in bio-nano systems

... surrounding water until it rebinds to the same or another filament. In order to understand the motor traffic in biological cells and in biomimetic systems, it is necessary to go beyond the single motor level and consider the cooperative behavior of many motors. To obtain a large flux of cargo transport, it...

Achilles heel of the herpes virus possibly found

...The receptor, dubbed B5, is made by most cells for another purpose not yet understood. HSV appears to have evolved a way to latch onto it, and fool the cell into letting the virus in. And since most cells express the gene for the B5 receptor, this may be a reason HSV can get into most kinds of cells. "This ...

Study shows humans have ability to track odors, much like bloodhounds

...uccessfully captured the mechanism." What's more, another area of the brain outside the olfactory cortex was very active during successful localization. This area, the superior temporal gyrus, is also involved in the localization of sounds and visual objects, Sobel said. "It's actually a very nice and eleg...

Scripps research scientists solve structure of a critical innate immune system protein

... Significantly, says Wilson, the structure is also another milestone of sorts. These membrane-spanning proteins are rich in repeats that contain a high percentage of the amino acid leucine. This fact was important to Wilson and his colleagues because the leucine-rich proteins are often decorated with sugars ...

To translate touch, the brain can quickly rearrange its sense of the body

...ry systems produced a rapid and profound change in another sensory system: The brain had changed the way it interpreted the signals from the sense of touch. These links between different bodily senses show that the brain constantly updates its internal map, and they shed light on the dynamic and flexible nat...

Scientists succeed in cloning human embryos from eggs matured in the lab

...om somatic cumulus1 cells (i.e. non-germ cells) of another person ?a process known as non-autologous nuclear transfer. After time for nuclear re-programming the oocytes were artificially activated by incubation in a medium containing calcium ionophore, which enabled the injected nucleus to prepare for the fi...

Biologists determine genetic blueprint of social amoeba

...properties of white blood cells. Three years ago, another team of UCSD biologists discovered that two genes that are used by Dictyostelium to guide the organism to food sources are also used to guide human white blood cells to the sites of infections and play a role in the spread of cancer. (see: http://ucs...

After time for nuclear re-programming the oocytes were artificially activated by incubation in a medium containing calcium ionophore, which enabled the injected nucleus to prepare for the fi...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

...7. The latest advancement, microbial nanowires, is another major milestone because it may usher in a new era of exploration of both microbial respiration and bio-electronics.?The findings, he said, are “promising and exciting,?although he emphasized the information must be independently confirmed and extende...

How monarch butterflies are wired for navigation

..." wrote the researchers. They also speculated that another such clock-related pathway of fibers they detected between two regions of the butterfly brain may play a role in regulating the insects' hormonal system, to induce the longevity that enables the butterfly to extend its survival in its overwintering g...

Purdue scientists may have found key to halting spinal cord damage

...team decided to see if the chemical was present in another slow-developing, seemingly untreatable condition: the degeneration of the spinal cord after initial traumatic injury. "Unlike most other parts of the body, spinal cord tissue does not heal after injury," Shi said. "After the initial shock, it actual...

Researchers identify new genes that regulate aging

...rohibited from working properly, and inhibition of another gene increases the length of life by 20%. The genes discovered affect a wide variety of activities, including insulin signaling, metabolism, and dietary regulation. Genes involved in insulin signaling are particularly interesting because correspondi...

New insights into how Huntington's disease attacks the brain

...ates, the disease strikes 30,000 people and places another 150,000 persons at risk. The disorder affects males and females equally and crosses all ethnic and racial boundaries. ...

A protein in the eye may prevent immune response and protect eyes from disease

...e. According to Stein-Streilein, the discovery is another piece of the "immune privilege" puzzle. Certain parts of the body, including the eyes, brain, gastrointestinal system and reproductive system have the ability to prevent the usual immune response onset when confronted with foreign invaders such as ba...

New tool reveals secrets of migrating cells

...olecules within the cells," she said. Robey, with another colleague, Philippe Bousso, last year published a review in the journal Immunity describing the contributions two-photo imaging has made to the field. Robey and Witt publish their current study in the May 3 issue of the Public Library Of Science-Biol...
