Cells re-energize to come back from the brink of death

...ancerous lack caspase and other proteins needed to support apoptosis after MOMP releases cytochrome c. But this victory over death is short-lived if CICD is activated. However, some cancerous cells not only dodge death from apoptosis by eliminating caspase activation, but they also foil CIDC. “Our study soug...

Researchers find 24 species believed new to science in Suriname rainforest

...palm swamp with freshwater sources clean enough to support abundant fish and amphibian life. Among the 24 species believed new to science are an Atelopus frog with brilliant purple markings, four Eleutherodactylus frog species, six species of fish, 12 dung beetles and an ant species. The scientists also f...

Bigger horns equal better genes

...ieve the horn length discrepancies are evidence to support the mutation accumulation theory of ageing, which is the idea that, because natural selection weakens with age, genetic mutations have effects that accumulate over time. Therefore, differences in genetic quality become more apparent as an organism ag...

Millions of children denied drug that costs less than $3 a year

...e limitations, the study provides more evidence to support the use of phenobarbital in developing countries. The burden of untreated epilepsy in terms of human suffering and social costs is enormous, says Professor Perucca. An efficient epilepsy management programme will work only if fully integrated ...

Migration alert -- How tumor cells home in on the lymphatic system

... Shields provide an explanation along with data to support it. Tumors produce excess fluid that continually percolates from the tumor towards nearby lymphatic vessels. The EPFL research shows how tumor cells use a clever chemical strategy to exploit this slow, one-way flow in order to migrate to functiona...

Massive herds of animals found to still exist in Southern Sudan

...ironment, Wildlife Conservation, and Tourism, with support from USAID/USDA, undertook ground surveys in 2001 and 2002 of the wildlife populations in Boma and confirmed the presence of white-eared kob in considerable numbers. At the time, aerial surveys could not be conducted due to the ongoing war. “We were ...

The electrical implants are also an approved therapy for other movement disorders and are at various stages of testing for ...

Lessons from the orangutans: Upright walking may have begun in the trees

...d branches, the orangutans used their arms more to support their weight, changing their moving style to incorporate hanging. They only tended to walk on all fours when navigating the largest branches, the researchers found. Hand-assisted bipedalism may have offered several advantages that allowed our arbo...

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

...ignal to the brain. The Patapoutian team’s results support the idea that activation of TRPM8 by temperature triggers cold sensation. "TRPM8 acts as a gate," says Dhaka, "At warm temperature it remains closed, but opens when exposed to cool temperature." The TRPM8-deficient mice did not lose their ability...

An antibody drug called Avastin, produced by Genentech, has been shown to block a major pro-angiogenesis molecule called vascular endothelial growth factor (VEGF), thus inhibiting the growth of vasculature. The drug has been used al...

Scientists: As rainfall changes, tropical plants may acclimate

That's a positive sign considering that as the Earth warms, some areas of the tropics are widely expected ...
