N. gonorrhoeae is a pathogenic bacterium that readily develops resistance to antibiotics such as sulfanilamides, penicillins, tetracyclines and…
Thus the course was set for solving further mysteries surrounding the world’s oldest glacier mummy. And now the next milestone has been reached: researchers…
The discovery, published in the Proceedings of the National Academy of Sciences, is part of a project funded by the Biotechnology and Biological Sciences…
Cancer cells that break free from a tumor and circulate through the bloodstream spread cancer to other parts of the body. But this process, called metastasis,…
In structural biology these include proteins, enzymes and viruses. A single change in their molecular structure can mean the difference between function and…
Researchers have identified an elusive gene responsible for Thrombocytopenia with Absent Radii (TAR), a rare inherited blood and skeletal disorder. As a…
For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and…
One of the first large-scale genomic studies conducted in a developing country has discovered genetic variants that elevate the risk for skin lesions in people…
Even though typical dance-floor activity might suggest otherwise, humans generally demonstrate a remarkable capacity to synchronize their body movements in…
They found that specific neurons in a brain region called the dentate gyrus serve distinct roles in memory formation depending on whether the neural stem cells…
Not all that glitters is gold. Sometimes it is just bacteria trying to get ahead in life. Many sea creatures glow with a biologically produced light. This…
Physical oceanographers and marine chemists at the Leibniz Institute for Baltic Sea Research in Warnemünde returned from their latest monitoring cruise (2-14…
The work, reported this week in the online Nature Communications, is a step toward biomedical devices with active components made from nanostructured systems.LEDs based on solution-processed inorganic nanocrystals have promise for use in environmental and biomedical diagnostics, because they are cheap to produce, robust, and chemically stable. But development has been hampered by the difficulty of achieving ultraviolet emission. In their paper, Los Alamos National Laboratory's Sergio Brovelli in collaboration with the research team lead by Alberto Paleari at the University of Milano-Bicocca in Italy describe a fabrication process that overcomes this problem and opens the way for integration in a variety of applications….
Some, for example, have syringe-like exterior structures that can pierce other cells and inject proteins. Another system, called a type VI secretion system, is…
For the past decade, scientists have been pursuing cancer treatments based on RNA interference — a phenomenon that offers a way to shut off malfunctioning…
Now Georgia Health Sciences University researchers report that an enzyme known to help keep a woman's immune system from attacking a fetus also helps block…
