Hopkins study suggests commercially available antibiotic may help fight dementia in HIV patients

...-2 absorbs the neurotransmitter glutamate from the space between neurons (the synapse), thereby preventing excess neuronal excitation, which in turn can cause cell death and brain damage. Ceftriaxone, used to treat pneumonias, sexually transmitted diseases, bacterial meningitis and other infections, is a ...

Inside rocks, implications for finding life on Mars

...ment that has never been done before. If a future space mission to Mars brings rocks back to Earth, Schopf said the techniques he has used, called confocal laser scanning microscopy and Raman spectroscopy, could enable scientists to look at microscopic fossils inside the rocks to search for signs of life,...

Secrets of the sea yield stronger artificial bone

AIDS drug from sunflowers

...refore recently sent some of his test objects into space in a rocket like that. 'We are investigating which genes plants switch on and off under particular gravity conditions,' he explains. 'However, with the methods we use we can also, for example, find out which genes the sunflowers activate when they pr...

Biologists visualize protein interaction that may initiate viral infection

...SIGN molecule, which means a significant amount of space is still available for that other receptor protein that people don't know about yet." Zhang said that the initial binding of the CRD and the virus might result in a "signaling event between the DC-SIGN molecule and the other primary receptor, leadin...

New analysis shows three human migrations out of Africa

...t reconstructed the history of the species through space and time. Three years later, he had 25 regions to analyze and the data provided molecular evidence of a third migration, this one the oldest, back to 1.9 million years ago. "This time frame corresponds extremely well with the fossil record, whic...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

...rs on this emerging discipline, as well as provide space for environmental metagenomics visitors to collaborate with CAMERA specialists. Over the next few years, CAMERA is expected to include other environmental or medical metagenomic datasets, as the novel cyberinfrastructure enables research in other dis...

First wolverine radio-collared in Pacific Northwest

...ide captured animals with a secure and comfortable space until they are released. A key reason for conducting this research is the need to understand the wolverine's habitat requirements in the Northwest and maintain the habitat without conflicting with other land uses. With help from satellites 600 mile...

MIT chemist discovers secret behind nature's medicines

...tute leaves more room in the active site -- enough space for the halide, in this case a chloride ion, to casually slip inside and bind to the iron, without the grand theatrics chemists had anticipated. After the iron and the chloride bind, the protein closes down around the active site, effectively pulling...

Minimal genome should be twice the size, study shows

...survival; each gene deletion reduces the available space for further reduction of the genome. "Including these alternative pathways into the minimal genome almost doubles its size." The researchers have developed a way of predicting bacterial genome content using two bacteria that have evolved from E.col...

Neurons find their place in the developing nervous system with the help of a sticky molecule

...olecule into the lateral ventricle, a fluid-filled space next to the neocortex. Application of an electrical current forced the RNA into neural progenitor cells, and it was subsequently inherited by their neuronal progeny that form layer 2/3 and blocked their ability to make MDGA1 protein. When Takeuchi...

Scaled-down genome may power up E. coli's ability in lab, industry

..."We wanted to know how the same genes that slice a space like a loaf of bread can also add slices one at a time," Brown said. According to Brown, the groundwork for this research was laid about 20 years ago when scientists first learned about the genes that regulate embryonic development in the fruit fly....

K-State researchers study gene regulation in insects

Stem cells from muscles can repair cartilage

... suggested that fatty tissue and tissue lining the space between joints (synovium) might also be sources of stem cells, obtaining these cells is more invasive than muscle biopsies. The author also notes that patients could potentially serve as donors to themselves, since the current study used MDSCs from j...

Still, Melnick and his colleagues are confident that their work represents a crucial step in efforts to protect an animal that is deeply rooted in Indian culture. "If we are going to find a way to protect elephants for ...

Penn study finds direct role for glial cells in brain cross-talk

...chemical signals called neurotransmitters across a space called the synapse. This process results in transmission of a nerve impulse. Historically, the glial cell or astrocyte was considered to be a support cell and to play no active role in regulating nerve impulse transmission. However, recent research ...
