Lasers Could Speed Cancer Testing
(PhysOrg.com) -- Photonics center explores new technology that might enable real-time diagnoses.
Scent of a spider: Sex pheromone of the wasp spider identified
(PhysOrg.com) -- Wasp spiders normally live alone. In their mating season, however, they look for a partner. To help them along, the females exude a chemical lure, a pheromone that has an irresistible scent to the males.
Three Interesting Uses for Mass Spectrometry
Sweet! -- sugar plays key role in cell division
Using an elaborate sleuthing system they developed to probe how cells manage their own division, Johns Hopkins scientists have discovered that common but hard-to-see sugar switches are partly in control.
Bacterial protein mimics its host to disable a key enzyme (w/ Video)
(PhysOrg.com) -- Bacteria use all sorts of cunning to trick hosts into doing their bidding. One con in their bag of tricks: the molecular mimic. In this ruse, bacteria or their agents look for all purposes like some native ...
New imagining technique could lead to better antibiotics and cancer drugs
A recently devised method of imaging the chemical communication and warfare between microorganisms could lead to new antibiotics, antifungal, antiviral and anti-cancer drugs, said a Texas AgriLife Research scientist.
Scientists visualize how bacteria talk to one another
Using imaging mass spectrometry, researchers at the University of California, San Diego have developed tools that will enable scientists to visualize how different cell populations of cells communicate. Their ...
Lab-on-a-Chip Performs 1,000 Chemical Reactions At Once
Flasks, beakers, and hot plates may soon be a thing of the past in medicinal chemistry labs. Instead of handling a few experiments on a benchtop, scientists may simply pop a microchip into a computer and instantly run thousands ...
Finding Better Ways to Diagnose Heart Attacks
(PhysOrg.com) -- UA biochemistry researchers apply Nobel Prize technology to develop better diagnostics for heart attacks. Their work also could help predict individual risks of heart disease.
New or not? Cracking cyclic natural products for new drugs
Researchers have invented computational tools to decode and rapidly determine whether natural compounds collected in oceans and forests are new—or if these pharmaceutically promising compounds have already ...
New biomarker method could increase the number of diagnostic tests for cancer
A team of researchers, including several from UCSF, has demonstrated that a new method for detecting and quantifying protein biomarkers in body fluids may ultimately make it possible to screen multiple biomarkers in hundreds ...
Circadian rhythms studies reveal new temperature regulator and track clock protein across a day
Dartmouth Medical School geneticists have made new inroads into understanding the regulatory circuitry of the biological clock that synchronizes the ebb and flow of daily activities, according to two studies published May ...
Plants may affect the effect of wildfires
(PhysOrg.com) -- Rising temperatures may lead to more tinder-dry vegetation, but that doesn't mean there will be a higher risk for wildfires in a particular area.
Interpretation will crack the microbial language code
In the environment, microbes often communicate with each other using small molecules. Ribosomally synthesized and posttranslationally modified peptides produced by microbes represent a class of metabolites ...
