Study shows continued success for new HPV vaccine against virus responsible for cervical cancer

...three shots of a new HPV vaccine marketed by Merck under the name Gardasil could make the difference in preventing cervical cancer. The vaccine targets HPV types 16 and 18, which cause about 70 percent of all cases of cervical cancer. It also targets HPV types 6 and 11, which together cause about 90 perc...

Dutch-sponsored researcher Agnieszka Doroszuk demonstrated this in her study into the long-term effects of environmental pollution on soil organisms. Environmental pollution is an important c...

Sleepless for science: Flies show link between sleep, immune system in Stanford study

...hm. In this case, these mutant flies could be kept under exactly the same light and temperature conditions as the normal flies. They looked at flies that were defective in one of two genes, called "timeless" and "period". They found that the loss of either gene's function made the flies more sensitive t...

As the result of new field work involving the Sonso chimpanzee community in Budongo Forest in Uganda, the St. Andrews researchers now report instances of three female-led infanticidal attacks. Alerted to the killings by sounds ...

Better health twice as likely for nonsmokers who live and work with smoking restrictions

...ol of Public Health found that nonsmokers who live under both a total household and total workplace smoking ban are over two and a half times more likely to report better health than those without smoking bans. The study surveyed 1,472 Chinese American adults who live and work in New York City. The stud...

Study warns deep-sea mining may pose serious threat to fragile marine ecosystems

...pecting and exploration of the seafloor into areas under national jurisdiction, where regulations are often weaker or non-existent. "The demand for metals is growing rapidly, and along with the sharp rise in metal prices, we have seen the depletion of metal-rich terrestrial mines," says Halfar. "For min...

Switching genes to overdrive improves muscular dystrophy symptoms in mice

... that increases or decreases the activity of genes under its control. Exercising a muscle raises PGC-1alpha levels, causing the formation of more mitochondria, the chemical power plants that create energy in cells. PGC-1alpha is also required for the normal operation of genes that control the developmen...

"With 170 known caves [on the BLM Arizona Strip lands], there is no doubt that there is more to find. The research we have con...

Corals that can fight global warming may one day help fragile reefs

..., not all corals are able to produce such defenses under thermal stress. "Some corals show unusual resilience to the double threat [of pathogens and warming seas], and we should look to these hardy corals for clues that might enhance others," said Harvell. "Other corals are more sensitive and will not surv...
