Early exposure to indoor fungus molecules may protect infants against future allergies

... the human immune system. "Fungi are a diverse group of microorganisms, so species differ in their glucan content and allergenic proteins. Some fungi also contain mycotoxins that can contribute to disease," adds Tiina Reponen, PhD, professor of environmental health and corresponding author of the study...

There is a growing appreciation of significant sex differences in cardiac characteristics and function in adult humans. A new research study begins to close the gender gap in fishes, and finds that sex differences in cardiac per...

'Personality-gene' makes songbirds curious

...k panther (see figure 2). The results from the group of selected birds were confirmed with data from free-living, unselected great tits. In the forest-living birds, the scientists also found a significant association between the SNP830-genotypes of individuals and variation in their level of curiosity....

Scripps research team sheds light on long-sought cold sensation gene

...s. TRPM8 was first discovered by Patapoutian’s group and proposed as a key gene controlling cold sensation. To test the hypothesis, the group observed the behavior of mice genetically altered to lack the gene in response to cold stimuli. ...

"In time, we can expect to completely replace gasoline and diesel with cellulose-derived biofuels that are cheaper, better for the environment and much better for national security than petroleum-derived fu...

8 plants from South Africa may hold potential for treating high blood pressure

...hese findings are in keeping with those of another group (1999). Further testing has revealed that the plant has promising hypotensive affects. The plant is commonly associated with onions and garlic and highly concentrated in Southern Africa. It is best known as "wild garlic." Researchers have record...

How to steer a moving cell

"This is the first time a group of researchers from several disciplines ?biologists, chemists, proteomics researchers and computational biologists who can integrate large data sets ?have applied a global approach to analyzing how proteins regulate cell movement." The research t...

Scientists: As rainfall changes, tropical plants may acclimate

... of the paper. "But of course, we only studied one group of organisms and one mechanism in this study" and plants depend on many different mechanisms to coexist, some of which may also change with changing rainfall. The scientists researched plant growth at six sites on the slopes of Mount Haleakala, a ...
