Primary care teams in England face a huge and unrealistic increase in workload in order to meet the goals of the national service framework for coronary heart disease, finds a study in this week's BMJ.

Specific genotype could increase resistance to HIV drug therapy
A specific mutation of a gene which influences the expression of a glycoprotein transporter protein involved in the body's resistance to drugs and other toxins is detailed in a research letter in this week's issue of THE LANCET.

New study puts dinosaur noses in their place
To the average dinosaur enthusiast, it may seem like an arbitrary question: Where, exactly, were dinosaurs' nostrils?

Dinosaurs had a "rostral nostril," says Science researcher
New research suggests that the fleshy nostril of dinosaurs may have been perched far forward within the bony nostril, not placed towards the back of the bony nostril as previously suggested.

Carnegie Mellon's solar powered robot demonstrates concept that could lead to long-term exploration of planets and moons
A prototype, solar-powered robot, developed with support from NASA by researchers at Carnegie Mellon University's Robotics Institute, has demonstrated a concept that could pave the way for future long-term robotic exploration of distant planets and moons.

Temple experts on heat-related injuries
The death of Minnesota Vikings offensive tackle Korey Stringer has raised national attention to the dangers of working out in the heat and humidity.

UCSD biologists identify genetic mechanism conferring resistance to 'Bt toxins'
Biologists at the University of California, San Diego have discovered the genetic and molecular means by which roundworms, and probably insects, can develop resistance to the most widely used biologically produced insecticide--crystalline toxins from the bacterium Bacillus thuringiensis, or Bt.

"COOL AID" safe after stroke, may deter side effect of clot-busters
Cooling the brain after an ischemic stroke may limit both initial tissue damage caused by a stroke as well as subsequent damage resulting from the restoration of blood flow after using clot-busting drugs, according to a report in the August issue of Stroke: Journal of the American Heart Association.

Designer chemical offers Alzheimer's hope
A research team led by Arun Ghosh and Jordan Tang report synthesis of highly potent inhibitor compounds which block action of memapsin-2, an enzyme which severs the APP brain protein, leaving Alzheimer-linked beta-amyloid as a byproduct.

Dinosaurs' large noses may have been key to physiological processes
With only bones for clues, scientists continue to puzzle over many details of dinosaur appearances and physiology.

The National Science Foundation (NSF) is proud to have funded this research by Lawrence Witmer of Ohio University.

Early detection of coeliac disease essential to prevent excess deaths
Death rates for people who have the intestinal disorder coeliac disease are twice that of the general population, conclude authors of a prospective study in this week's issue of THE LANCET.

American Thoracic Society Journal News Tips for July (Second Issue)
Newsworthy research appearing in the second of two July issues of the ATS journal includes studies showing that snorers and persons with obstructive sleep apnea (OSA) demonstrated upper airway sensory impairment which could trigger airway obstruction; an expert view that the airway sensory dysfunction could be caused by motor neuron lesions in some snorers and in most with OSA; the use of low-tidal ventilation in the critically-ill works equally well across all clinical subgroups.

Low cholesterol linked to increased mortality in elderly people
Low cholesterol, a key health objective for reducing cardiovascular disease, could be associated with higher death-rates among elderly people, conclude authors of a study in this week's issue of THE LANCET.

NYU researchers successfully immunize mice against Alzheimer's
NYU School of Medicine researchers have prevented the development of Alzheimer's disease in mice genetically engineered with the human gene for the disease using a new vaccine.

Challenging long-standing beliefs about the international burden of malaria, scientists have presented new information about the severity of malaria morbidity, mortality, and its economic toll in a supplement to The American Journal of Tropical Medicine and Hygiene.

Why patients request euthanasia or physican assisted suicide
A qualitative study in this week's issue of THE LANCET provides a new insight into why patients request euthanasia or physician-assisted suicide.

Scientists find genetic basis of insect's resistance to engineered crops
Some experts fear that increased use of bioengineered crops with built-in insecticides could backfire and actually spur the development of genetically resistant pests.

Cocaine-related deaths, drug-related emergency visits drastically increasing, UT Southwestern researchers report
Physicians should consider the possibility of cocaine use as a culprit when young adults are brought to emergency rooms for nontraumatic chest pains, according to researchers at the UT Southwestern Medical Center at Dallas.
