Does God answer prayer? ASU research says 'yes'

...ting a meta-analysis takes into account the entire body of empirical research on intercessory prayer. Using this procedure, we find that prayer offered on behalf of another yields positive results.? Hodge’s work is featured in the March, 2007, issue of Research on Social Work Practice, a disciplinary jo...

Scripps research team discovers a chemical pathway that causes mice to overeat and gain weight

...ng this time. The increased activity led to higher body temperatures, but this did not burn enough extra calories to balance the additional eating, so the mice weighed 15 to 30 percent more than control mice. Determining why the lack of EP3 receptors causes increased activity and eating will likely tak...

Bioluminescence at the service of a novel cerebral imaging technique

...nt-type markers. Such recordings of the ellipsoid body have thus demonstrated the considerable sensitivity of this novel approach, while validating access to all structures, even those located deep in the brain. It will therefore be possible to study all neurons or cerebral structures using this approac...

Bats prey on nocturnally migrating songbirds

...heaviest aerial-hunting bats of the world. A large body mass (up to 50 g for 45 cm wingspan) is probably a prerequisite for subduing prey items as large as passerines, which have approximately the same weight as other European bat species. The extraordinary predatory specialization of the giant noctule...

Genes may determine success of hip replacement surgery

DNA samples were taken from all participants to test for genetic variations in genes responsible for generating matrix metalloproteinase 1, or MMP1 for short, in...

New species declared: Clouded leopard on Borneo and Sumatra

Between 5,000 and 11,000 clouded leopards are estimated to live on Borneo. The total number in Sumatra could be in the range of 3,000 to 7,000 individuals. However, further s...

New antibacterials being developed to tackle MRSA superbug

... in hospitals. It may then spread further into the body and cause serious infections such as blood poisoning. Methicillin-resistant Staphylococcus aureus, or MRSA, is a form of the bacterium that is resistant to the drug methicillin and a number of other antibiotics and tends to be more difficult to treat...

Twin studies reveal genetic components leading to cardiac and kidney disease

40,000-year-old skull shows both modern human and Neandertal traits

...But this fossil is a major addition to the growing body of fossil, genetic and archaeological evidence indicating significant levels of biological and cultural interaction between modern humans and the anatomically archaic populations (including the Neandertals) they met along the way as they spread from ...

Trojan horse strategy defeats drug-resistant bacteria

Iron is critical for the growth of bacteria and for their ability to form biofilms, slime-encased colonies of microbes...

However, previous approaches required an antibody that looked promising to be transferred from bacteria to mammalian cells to pursue large-scale, commercial production. Getting mammalian...

Inflammation may play role in metastasis of prostate cancer

...that "mounting an immune response" or "having your body fight the cancer" is a good thing. Now, research at the University of California, San Diego (UCSD) School of Medicine strongly suggests that inflammation associated with the progression of tumors actually plays a key role in the metastasis of prosta...

Mosquito repellents that emit high-pitched sounds don't prevent bites

Although the researchers found no direct evidence on whether EMRs prevent malaria, t...

While there is already a substantial body of evidence showing that cutting back on salt lowers blood pressure, studies showing subsequent levels of cardiovascular disease in the population have been limited and inconclusive. This research provides some of the strongest objective evidenc...
