Greenpeace veröffentlicht heute seinen aktuellen Fischratgeber. Dieser gibt Verbrauchern die notwendigen Informationen für einen nachhaltigen Fischeinkauf. Die Devise des Ratgebers lautet: Weniger Fisch ist mehr. Verbraucher sollten seltener und bewusster Fisch essen. Und wenn, dann zu Fisch aus ökologisch nachhaltigen Fischereien und Aquakulturen greifen. (more…)
A new study in the New England Journal of Medicine documents the high-profile failure of a promising drug, bapineuzumab, to slow cognitive decline in dementia patients. Dr. Stephen Salloway, the study’s lead author, says researchers have learned key lessons that they are eager to apply in new attempts to find effective treatments for Alzheimer’s disease. (more…)
People who enjoy life maintain better physical function in their daily activities and keep up faster walking speeds as they age, compared with people who enjoy life less, according to a new study led by Professor Andrew Steptoe (UCL Epidemiology & Public Health). (more…)
A new class of molecules called acyldepsipeptides — ADEPs — may provide a new way to attack bacteria that have developed resistance to antibiotics. Researchers at Brown and MIT have discovered a way to increase the potency of ADEPs by up to 1,200 times. Their findings appear in the Journal of the American Chemical Society.
PROVIDENCE, R.I. [Brown University] — As concerns about bacterial resistance to antibiotics grow, researchers are racing to find new kinds of drugs to replace ones that are no longer effective. One promising new class of molecules called acyldepsipeptides — ADEPs — kills bacteria in a way that no marketed antibacterial drug does — by altering the pathway through which cells rid themselves of harmful proteins.

Attitudes toward over-indulgence, obesity and body shape were being hotly debated and used for political purposes as early as the 19th century, a new book claims. ‘Pathological Bodies’, by Dr Corinna Wagner from the University of Exeter, shows that body consciousness is not just a modern-day phenomenon.
Instead, medical warning about excessive eating and drinking, and public attitudes about self-control and discipline emerged more than 250 years ago, when the perceived decadence of the Georgian period gave way to the more moderate and austere approach adopted by the Victorians. (more…)
A new drug, called pritelivir, may offer a new treatment option for patients with genital herpes, a new industry-sponsored – study led by University of Washington researchers has found.
The study appears in this week’s issue of the New England Journal of Medicine. The lead author is Anna Wald, M.D., professor of medicine, epidemiology, and laboratory medicine, and medical director at the Virology Research Clinic at the University of Washington. Other UW coauthors include Dr. Amalia Magaret, Dr. Christine Johnston, Dr. Lawrence Corey, Dr. Meei-Li Huang and Stacy Selke. (more…)
Study identifies essential molecule for transport of protein from neuron cell body to axon
COLUMBUS, Ohio – Scientists have solved a longstanding mystery of the central nervous system, showing how a key protein gets to the right spot to launch electrical impulses that enable communication of nerve signals to and from the brain.
Nerve impulses are critical because they are required for neurons to send information about senses, movement, thinking and feeling to other cell types in the neural circuitry. And an impulse is not fired up just once; it is initiated and then must be repeatedly transmitted along axons – long, slender extensions of nerve cell bodies – to keep the nervous system’s messages stable during their rapid travel.

Almost one in 10 people will someday experience a kidney stone, which creates what is described as the most intense pain imaginable. This increasingly common condition leads to hundreds of thousands of surgeries in the United States each year.
A new device developed at the University of Washington would let doctors use ultrasound to move kidney stones inside the body and help them pass by natural means. (more…)
