Johns Hopkins scientists have discovered how two closely related proteins guide projections from nerve cells with exquisite accuracy, alternately attracting…
They become erratic and zombie-like, and are manipulated by the fungus into dying at a spot that provides optimal conditions for fungal reproduction. New…
Their latest findings, published today in Molecular Cell, demonstrate that telomerase repairs chromosomes in one of two ways – depending on whether a cell is…
A new strategy for synthesizing the kind of complex molecules that certain bacteria use to build their protective cell walls has been developed by Akihiro…
All living organisms are dependent on water, but this is especially true for plants. Limited access to water is one of the decisive factors for humans to be…
That ability translates to the human world. Transportation Security Administration screeners can pick out dangerous objects in an image of our messy and…
The work could help shed light on health-related problems such as how cancerous cells spread, what makes some people more prone to heart attacks,…
Jointly, such gene expression status of each gene in the genome, measured as the level of their transcripts, constitutes the gene expression profile. Since…
The study, recently published online ahead of print by Nature Chemical Biology, is the first to find such a sensor in immune cells—specifically, in the T…
A group of researchers at Karolinska Institutet and the Max Planck Institute for Biology of Ageing has discovered that a protein called MTERF4 combines with…
DNA from Helicobacter pylori, a common stomach bacteria, minimizes the effects of colitis in mice, according to a new study by University of Michigan Medical…
What causes a virus to suddenly begin infecting large numbers of people?Scientists have long known that the process they call “viral emergence” involves a wide…
WHAT:Using a monkey model of AIDS, scientists have identified a vaccine-generated immune-system response that correlates with protection against infection by…
For much of the time our T cells—the white blood cells that act as the police of the immune system—are in what immunologists call a “quiescent state,” a sort…
Jody Banks, a professor of botany and plant pathology, led a team of about 100 scientists from 11 countries to sequence the genome of Selaginella, a lycophyte….
The difference in complexity between human and primitive organisms results from the ways in which the functions of genes are elaborated, rather from just the…
