Scientists pinpoint inflammation gene

...iven the results in animals, the SFBR-led team was brought in to determine whether this gene is relevant to inflammation in humans. Blangero, who designed the study, first teamed up with Kissebah and the large-scale, family-based study Kissebah leads with TOPS members. This study population is ...

Mining biotech's data mother lode

The BioGrid project brought together six partners from the UK, Germany, Cyprus and The Netherlands to address one of the key problems facing the life sciences today. "How to integrate the huge volume of disparate data ?on gene expression, protein interactions and the vast outp...

Sperm stem cells closer to being like embryonic stem cells

...em cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body. Researchers at the Cecil H. and Ida Green Center for Reproductive Biology Sciences at UT Southweste...

Seal rookeries could provide a reliable food source for endangered California condors, study finds

... tallow and leather. Many thousands of cattle were brought here, so the condors switched their whole diet to cattle." The large cattle ranches disappeared within a few decades, once leaving the condors without a reliable food source. "After the cattle were gone, condors starting getting rarer and hence more...

Sleeping sickness parasite shows how cells divide their insides

Researchers at Yale have brought to light a mechanism that regulates the way an internal organelle, the Golgi apparatus, duplicates as cells prepare to divide, according to a report in Science Express. Graham Warren , professor of cell biology , and his colleagues at Yale study T...

Open Source Biotechnology alliance for international agriculture

Tropical Atlantic cooling and African deforestation correlate to drought, report scientists

...id. The authors state, "periods of drought likely brought about environmental hardship, triggering population migration, giving rise to changes in the modes of agricultural production, and influencing the fall or rise of civilizations." Weldeab points out that the past 50 years are marked by deforestation ...

Predators keep the world green, ecologists find

The second instrument developed by Jaspers is a mechanical manipulator for operating the various instruments used in keyhole surgery. Two mechanical arms, provided with artificial 'wrist joints...

Study in Science holds promise for a new approach to drug therapy

... site of infection. The other involves pain relief brought about by morphine. In white blood cells, the free G protein gamma-beta subunit activates enzymes that allow the cells to home in on the site of infection. Researchers found that pre-treatment of white blood cells with M119 reduced activation of enz...
