How 'memory' T cells curb the spread of viruses throughout the body

...ferate, but also are the sites where a major fight against the spread of an invading virus occurs. After becoming sick from many viruses, the body becomes “immune” (protected) from recurrence of the same disease. This is why before vaccines were developed, childhood diseases such as measles and mumps occur...

Researchers identify protein pathway involved in Parkinson disease development

...Although cells have mechanisms in place to protect against oxidative damage, this system can break down in the face of environmental challenges or genetic mutations. The Emory researchers found that the mitochondrial protein PINK1 normally protects cells from oxidative stress and promotes cell survival b...

Smoking rate has plummeted in New York City

...g rate has plummeted since a comprehensive program against smoking was launched in 2002, according to findings issued today in the national Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report (MMWR). The 2006 rate was nearly 20% lower than the 2002 rate -- a decline that repres...

Experts predict Tamiflu could halve the pandemic influenza death toll versus no intervention

... at the University of Michigan. “Tamiflu is active against all types of influenza virus and will be immediately available during a pandemic if stockpiles are adequate. The big question is, should we be stockpiling for treatment only or for both treatment and prophylaxis"”...

Definitive evidence found of a swimming dinosaur

...ace of the site indicate the dinosaur was swimming against a current, struggling to maintain a straight path. "The dinosaur swam with alternating movements of the two hind limbs, a pelvic paddle swimming motion," said Costeur. "It is a swimming style of amplified walking with movements similar to those us...

New study suggests potential for a broadly-protective HIV vaccine

...may be possible to develop a vaccine that protects against the myriad strains of the HIV virus. HIV is extremely variable, so an effective vaccine may need to stimulate the body to produce cross-reactive antibodies that will neutralize multiple viral strains. These results demonstrate that induction of truly...

Mule deer moms rescue other fawns

Whitetails rely on flight rather than fight for most of their lives, so this may affect their ability to mount an aggressive defence...

Amphibians in losing race with environmental change

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

... special phenoloxidase inhibitor to protect itself against this particular defence. They identified the inhibitor as a small molecule called 1,3-dihydroxy-2-(isopropyl)-5-(2-phenylethenyl)benzene, known as ST for short. This molecule is also an antibiotic and Photorhabdus produces it to kill off other...
