Quick changes in behavior – in worms, at least – can be triggered by a unique form of the molecule RNA acting within the nucleus of a cell, UC San Francisco researchers have discovered.
A healthy ear is much better at detecting and transmitting sound than even the most advanced hearing aid. But now researchers reporting in the August 20 issue of the Biophysical Journal, a Cell Press publication, have uncovered ...
Short-term gene-expression 'memory' is inherited in proteins associated with DNA, new research finds
(Phys.org) —By studying a gene in yeast, a team of scientists has found that modifications to histones—proteins associated with DNA—can control whether or not a gene is allowed to function and may be important in maintaining ...
Research on human embryonic stem cells has been a political and religious lightning rod for more than a decade.
Many scientists use animals to model human diseases. Mice can be obese or display symptoms of Parkinson's disease. Rats get Alzheimer's and diabetes.
Hungry people are often difficult to deal with. A good meal can affect more than our mood, it can also influence our willingness to take risks. This phenomenon is also apparent across a very diverse range of species in the ...
Scientists from the Florida campus of The Scripps Research Institute (TSRI) have found a compound that could counter Parkinson's disease in two ways at once.
Neuroscientists may soon be modern-day harpooners, snaring individual brain-cell signals instead of whales with tiny spears made of carbon nanotubes.
A mechanism that cells use to group together and move around the body – called 'chase and run' - has been described for the first time by scientists at UCL.
(Phys.org) —Fruit flies may have more individuality and personality than we imagine.
