The penguin initially carries sufficient oxygen in three stores – the blood, lungs and myoglobin in muscle – to sustain aerobic metabolism. However, around 5.6…
Some clouds cool the earth. But how are these clouds formed? How does the chemistry of the ocean affect their formation? Is this process affected by climate…
Scientists have discovered that marine diatoms, tiny phytoplankton abundant in the sea, have an animal-like urea cycle, and that this cycle enables the diatoms…
All animals move – cheetahs faster, snails more slowly. Muscle contractions are the basis of all movements, at least according to general opinion. But there…
In papers recently published online by the journal Environmental Science & Technology, one research team looked at the levels of persistent organic pollutants…
Because they have a variety of useful properties, especially as antibacterial and antifungal agents, silver nanoparticles increasingly are being used in a wide…
The investigators have used a new ultra-sensitive test that employs technology developed at UMDNJ that not only can better diagnose Aspergillus infections, but…
Published in the April 28th issue of the journal PLoS Genetics, the finding contributes to advancing our understanding of a broad range of biological processes…
Scientists at the Reference- and Translation Center for Cardiac Stem Cell Therapy at the University of Rostock (RTC) are now able to visualize molecules with a…
A person’s vulnerability to nicotine addiction appears to have a genetic basis, at least in part.A region in the midbrain called the habenula (from Latin:…
Johns Hopkins scientists have discovered how two closely related proteins guide projections from nerve cells with exquisite accuracy, alternately attracting…
The study, done in mouse models of metastatic melanoma that had spread to the brain, has important clinical implications, as the method could boost the…
Fish accustomed to living near the light of the water’s surface become proverbial “fish out of water” when they move to dark environments like those found in…
Probiotic bacteria promote healing of the intestinal lining in mice by inducing the production of reactive oxygen species, researchers at Emory University…
Even the merest of microbes must be able to talk, to be able to interact with its environment and with others to not just survive, but to thrive.This cellular…
Yeasts are unicellular fungi and so far over 1 500 different species have been described. Among them are important industrial organisms, pathogens and model…
