How E. coli bacterium generates simplicity from complexity

...nt environments in computer simulations. "When it comes to genomes, a great deal of complexity boils down to just a few simple themes," said Bernhard Palsson, a professor of bioengineering at UCSD's Jacobs School of Engineering and co-author of the study, which was made available online Dec. 15. "Research...

Jefferson scientists identify gene defect leading to abnormal skin development and cancer

...in streambeds. It also kills every invertebrate it comes in contact with, and sometimes fish. The lampricide is tanker-trucked to streams, some of them in populated areas, in an expensive, labor-intensive and unpopular undertaking. The GLFC is eager to use a synthetic form of the newly found pheromone to r...

Penicillin, amoxicillin: Step aside for strep throat treatment

...e penicillin and amoxicillin to step aside when it comes to the treatment of strep throat. The most common medications used to treat the strep germ, the bug that causes millions of sore throats in U.S. children every year, simply aren't doing the job and aren't as effective as newer antibiotics known as c...

'Perception' gene tracked humanity's evolution, scientists say

...ption is unknown. Evidence for its various effects comes entirely from clinical studies of people who have mutations in the gene. Past clinical studies have also indicated a positive correlation between lower prodynorphin levels in the brain and susceptibility to cocaine dependence. Matthew Rockman, Davi...

Max Planck researchers make a breakthrough in plant stem cell research

...ny years, developing new organs. But this ability comes at a price. If the number of meristematic stem cells increases too quickly, then there could be uncontrolled growth, similar to cancer. On the other hand, if the stem cell pool shrinks too quickly, the plant could have stunted growth. In order to sta...

Researchers know what you were about to say; fMRI used to detect memory storage and retrieval

"It is all part of the brain's ability to cross-reference memories...

Newly discovered birdlike dinosaur is oldest raptor ever found in South America

...n of Buitreraptor is superb, and the rock layer it comes from represents the oldest interval of the Late Cretaceous," Apestegua says. "The rich fauna of this area, known as La Buitrera, includes other carnivorous dinosaurs, such as mid-sized abelisaurs and the gigantic Giganotosaurus. However, the most c...

Male elephants woo females with precise chemistry

... a temporal gland located between the eye and ear, comes in two forms, each representing one half of the enantiomer pair and identified as either "plus" or "minus." The OHSU and New Zealand team showed that the enantiomers of frontalin are released in the elephants in specific ratios that depend on the an...

New clues to the dark side of a key anti-tumor guardian

...t it also represents an intriguing paradox when it comes to the broader roles this protein plays in our well being. Past work has shown that in animal models, hyperactivation of the p53 protein is beneficial in terms of bestowing extra protection against tumor formation, but at the same time it has a signi...

Computer models aid understanding of antibody-dependent enhancement in spread of dengue fever

But there comes a point where the predator gets so good it runs out of prey," explained lead author Derek Cummings, a research associate in the Department of International Health at the Bloomberg School. "We found that antibody-dependent enhancement helps the dengue...

DNA size a crucial factor in genetic mutations, study finds

...the PNAS study. DNA, the genetic encoder of life, comes in two parallel strands that form a double helix. It's like a long, twisted ladder where each rung consists of two molecules that form a base pair. DNA has four bases: adenosine (A), thymine (T), guanine (G) and cytosine (C). A always pairs with T, a...

The story of a "jack of all trades" circulating via the blood stream throughout the body and repairing, wherever needed, any type of tissue is, unfortunately, a myth. In practice their impact...

Prions rapidly 'remodel' good protein into bad, Brown study shows
