Study Provides New Genetic Clue to Anorexia
The largest DNA-sequencing study of anorexia nervosa has linked the eating disorder to variants in a gene coding for an enzyme that regulates cholesterol metabolism....
Artificial Nose Sniffs Out Blood-Poisoning Germs
Disease-causing bacteria stink -- literally -- and the odor released by some of the nastiest microbes has become the basis for a faster and simpler...
Possibility of Selectively Erasing Unwanted Memories
The human brain is exquisitely adept at linking seemingly random details into a cohesive memory that can trigger myriad associations -- some good, some not...
Genome of Elastomeric Materials Creates Novel Materials
A wide range of biologically inspired materials may now be possible by combining protein studies, materials science and RNA sequencing, according to an international team...
Programmable glue made of DNA

UC Davis team “spikes” stem cells to generate myelin
Stem cell technology has long offered the hope of regenerating tissue to repair broken or damaged neural tissue. Findings from a team of UC Davis...
One gene lets mice smell danger
When a mouse smells a cat, it instinctively avoids the feline or risks becoming dinner. How? A Northwestern University study involving olfactory receptors, which underlie...
Epigenetic factors play a role in senescence
Researchers from the Perelman School of Medicine at the University of Pennsylvania have found that epigenetic factors play a role in senescence. Epigenetic factors act...
Bioengineers invent portable device for common kidney tests
A lightweight and field-portable device invented at UCLA that conducts kidney tests and transmits data through a smartphone attachment may significantly reduce the need for...
Scientists have grown a tiny brain in a dish
Scientists at the Institute of Molecular Biotechnology in Vienna, Austria, have grown three-dimensional human brain tissues from stem cells. The tissues form discrete structures that...
Human brain-to-brain interface
