Biofilm reorganization: Back to the theoretical drawing board
In a surprising new study, researchers using image-analysis methods similar to those employed in facial-recognition software have made a startling discovery that rules out the two main theories scientists ...
Method reveals new view of human nerve cells, opening door to potential drug targets
Scientists at The Scripps Research Institute and University of Pennsylvania have found a way to uncover potential drug targets that have so far remained hidden from researchers' view.
'GPS system' for protein synthesis in nerve cells gives clues for understanding brain disorders
Scientists at the University of Pennsylvania explain how a class of RNA molecules is able to target the genetic building blocks that guide the functioning of a specific part of the nerve cell. Abnormalities at this site are ...
Tiger poo repels Australia's pests: scientist
Tiger poo is an effective new weapon in warding off animal pests, scientists said Wednesday, after years of experimenting with big cats' faeces collected from Australian zoos.
Antifungal compound found on tropical seaweed has promising antimalarial properties
A group of chemical compounds used by a species of tropical seaweed to ward off fungus attacks may have promising antimalarial properties for humans. The compounds are part of a unique chemical signaling system ...
Structure, dynamics of a chemical signal that triggers metastatic cancer revealed
In cancer and other pathological diseases, researchers are discovering that packaging is important: specifically, how DNA about two meters long when unwound and stretched coils up and compacts ...
Human and mouse studies sharpen focus on cause of celiac disease
Blocking a factor that can activate the human immune response against intestinal bacteria or certain foods could prevent the development of celiac disease in those most at risk, researchers report in the journal Nature.
Nailing down a crucial plant signaling system
Plant biologists have discovered the last major element of the series of chemical signals that one class of plant hormones, called brassinosteroids, send from a protein on the surface of a plant cell to the cell's nucleus. ...
Detecting, treats tumors, and monitoring response to therapy with gold 'nano-popcorn'
Using a two-step process that creates gold nanoparticles that look like kernels of popcorn, researchers at Jackson State University have created a targeted nanoparticle that can detect as few as 50 malignant prostate cells ...
Scientists investigate how chemicals evolved into communication signals
Scientists discover a chemical signal in human tears
Emotional crying is a universal, uniquely human behavior. When we cry, we clearly send all sorts of emotional signals. In a paper published online today in Science Express, scientists at the Weizmann Instit ...
Fruit fly study digs deeper into poorly understood details of forming embryos
Using fruit flies as a model to study embryo formation, scientists report in Nature Cell Biology that molecular breakdown of a protein called Bicoid is vital to normal head-to-tail patterning of the insect's offspring.
Team develops 'logic gates' to program bacteria as computers
A team of UCSF researchers has engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations.
New path for colon cancer drug discovery
An old pinworm medicine is a new lead in the search for compounds that block a signaling pathway implicated in colon cancer. The findings, reported by Vanderbilt University Medical Center researchers in the ...
