Langerhans cells regulate immune reactions in the skin

...lupus and skin cancer. Dendritic cells are found throughout the body and are extremely efficient at alerting the immune system to the presence of pathogens and other foreign materials. Langerhans cells are dendritic cells in the skin. Skin is an important barrier to infection and it has been generally assumed...

In SAD patients, autumn antidepressants can prevent winter depression

"These are the first system...

NIH launches comprehensive effort to explore cancer genomics

...of all cancers. This atlas will enable researchers throughout the world to analyze and use the data in their own research to develop new diagnostics and therapies for different cancers. Recognizing that not all technologies needed for high-throughput, cost-effective analysis of the cancer genome are already i...

Anyway you slice it, tomatoes cut through drought with new gene

...said. The paper notes that drought conditions throughout the world each year carve out a huge amount of food production. To overcome food shortages, the authors suggest, "it will be necessary to increase the productivity of land already under cultivation and to regain the use of arable land lost to sc...

New study pinpoints epicenters of Earth's imminent extinctions

...es of South America, in Brazil's Atlantic Forests, throughout the Caribbean, and in Madagascar. "Although saving sites and species is vitally important in itself, this is about much more," said Mike Parr, Secretary of AZE. "At stake are the future genetic diversity of Earth's ecosystems, the global ecotouris...

Getting old? Slowing down? Blame inefficient mitochondria

...l to generate ATP, an energy unit that can be used throughout the cell. Just as you can work out a power station's efficiency by seeing how much electricity it produces for each unit of oxygen and fuel it burns, you can assess the efficiency of mitochondria by monitoring the amount of ATP produced for every un...

New book on rain forests, slash-and-burn agriculture

...orests and cleared land in several benchmark sites throughout the developing world. It is based on the first decade of work by the Alternatives to Slash-and-Burn consortium, which was formed in 1992 by a group of concerned national and international researchers. Its authors include agronomists, foresters, econo...

Alleged 40,000-year-old human footprints in Mexico much, much older than thought

.... Because the Earth's field has repeatedly flipped throughout the planet's history, it is possible to date rock based on its magnetic polarity. Feinberg found that the rock grains in the volcanic ash had polarity opposite to the Earth's polarity today. Since the last magnetic pole reversal was 790,000 years ag...

MRSA use amoeba to spread, new research shows

Evidence with other pathogens suggests that pathogens that emerge from amoeba are more resistant to antibiotics and more virulent. "This makes matters even more worrying," said Professor Brown. "It is almost as though the ...
