U-M researchers take new approach to defeating Gram-negative bugs

...y weakening it, Woodard's team found E. coli would die in the presence of normal levels of bile salts to which the bacteria would be exposed in the human gut. Besides differing in how they respond to Gram's coloring test, Gram-positive and Gram-negative bacteria look different. Gram-positive cells are s...

For the first time: Longevity modulated without disrupting life-sustaining function

...able to slow down the aging process, and the worms die young. "These mutants are shorter lived because they are unable to respond appropriately to oxidative stress, but they are just as resistant to heat stress as wild type worms whose signaling pathways have not been experimentally manipulated," explai...

Researchers discover way to transport environmental arsenic to plant leaves in new clean-up strategy

...le in northern India and Bangladesh may ultimately die of diseases resulting from arsenic-related poisoning. The new strategy is part of what researchers call phytoremediation--the cleaning of polluted soils through the use of plants that sequester poisons, make them less harmful, and which can then be ...

Blood flow in brain takes a twist, affecting views of Alzheimer's

... In Alzheimer's it's known that neurons sicken and die over a period of years. To diagnose the disease, doctors often order a brain scan. When the test shows lessened blood flow, doctors assume that there must be less of a demand for blood, and so significant numbers of neurons in that brain region must ...

Genetically engineered mosquitoes show resistance to dengue fever virus

James, a professor of microbiology and molecular genetics, and of molecular biology and biochemistry, has made a number of significant advances on genetic approaches to interrupt malaria parasite and dengue virus transmiss...

Scientist warns of threat to last stronghold of endangered turtle

...cies each year. Of these, thousands are thought to die as a result. Approximately 1.4 billion hooks are cast into the world's oceans as part of industrial long-line fishing, with 37% of this fishing effort in the Atlantic. A major hotspot is found off West Africa, the focus of this study. With fishing...

A large step forward in the fight against African sleeping sickness

Each year, over 300,000 people die of African sleeping sickness (trypanosomiasis). Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to the Free University of Brussels are making strides in the battle against this disease. They have coupled th...

Loosen leash on cancer protein 'watchdog,' researchers say

Molecular force field helps cancer cells defend against attack

...pped cancer cells from dividing and caused them to die but spared normal breast cells. "FAK is a critical molecule, and in the future different ways of targeting either the enzyme itself or targeting the binding between these various proteins will have a major impact on cancer, I believe," Cance said.

A step forward in the fight against bacterial infections

...they can be fatal. In the US, about 200,000 people die from bacterial infections each year. Normally, our natural immune system bars bacteria from entering our body, or it renders them harmless. The aggressiveness of the bacteria, our general state of health, and the speed with which our immune system re...

A case of mistaken molecular identity

... or years after being infected. Some 30,000 people die each year from Chagas disease, according to the World Health Organization, but the number of people who are carrying latent infections is unknown. "We now know that Chagas patients may have trouble seeing at night," said Levin. "And this gives us a...

These processes, scientists say, reflect a critical tradeoff between tree growth and survival. Temperate trees have to stop growing and go dormant in the winter or they literally freeze to death.

Cincinnati surgeons report new treatment for often-fatal injury

If the outer layer remains intact, however, a weakened area called a pseudoaneurysm can form, which often bursts later. Surgeons must repair the damaged aorta quickly before it does rupture, killing the patient. ...

Roughly one third of the world's population is infected and more and more bacterial strains have developed resistance to drugs. Researchers from the Hamburg Outstation o...

As the baby boomer generation gets older, it is predicted that the number of hip fractures may triple by 2020 unless better prevention and treatment for the disease is improved.
