Multi-million pound UK Biobank underway

...round 10 million biological samples, which must be kept at between -80?C and -200?C for several decades. When UK Biobank is running nationwide, this robotic system will need to handle samples taken from around 1,000 people every day. Dr Tim Peakman, executive director of UK Biobank and in charge of runni...

Genomics-based vaccine could prevent deadly cattle disease

...s. In particular, East Coast fever kills cattle kept by families trying to rise out of poverty. If researchers are successful, Nene notes, the entire region will have new reason to hope for a better life. Evans Taracha, ILRI project leader, also highlights the importance of strategic research partnersh...

In addition to last year's 38 U.S. attacks, Burgess tracked 10 in Australia, four in South Africa and one each in the Bahamas, St. Martin, Mexico, Fiji, Vanuatu and South Korea. Compared with previous years, the n...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

...v, Beer Sheva. It was reported before that rats kept in an environment rich with mental stimulations and opportunities for physical activity exhibit increased formation of new nerve cells in the hippocampus. In the present work, the scientists showed for the first time that formation of these new nerve...

Formation of cellulose fibers tracked for the first time

...h specific drugs, the cellulose synthase molecules kept moving, but they followed different, less directed patterns. "Many scientists had suspected a relationship between cellulose synthase and microtubules, but the exact nature of the interaction was hard to pinpoint," Ehrhardt said. "The microtubules a...

UCI researchers discover key factor for survival of human embryonic stem cells

...extremely difficult," Donovan said. "This fact has kept us from producing enough cells to be useful for therapy, and has limited our ability to genetically manipulate the cells, which we must do before they can be transplanted into patients. It appears that if we treat hES cells with neurotrophins, we can...

The starling is mentioned only once in all of Shakespeare, but in that passage an angry warrior, forbidden by the King to speak of a rival, Mortimer, decides he will "have a starling shall be taught to speak nothing but 'Mortimer,' and g...

HIV accessory protein disables host immunity via receptor-protein intermediary

...corticoid receptor protein. When the researchers kept the glucocorticoid receptor protein from being made, Vpr did not kill host cells. "This indicated that glucocorticoid receptor function is not what's really necessary for Vpr activity," says Weiner. "The glucocorticoid receptor-Vpr complex must be in...

Picking particles faster than one at a time

...n't easy. The microscope's electron beam has to be kept at low power to prevent radiation damage, so the signal-to-noise ratio is low and the particles are barely perceptible shapes in a field of gray. "It's hard to find good candidates even with an expert eye," says Adiga. "Having to choose hundreds of...

Sperm stem cells closer to being like embryonic stem cells

Blocking the nerve receptor EP1 in mouse models reduces brain damage caused by stroke

...n produces PGE2. "A lot of the previous findings kept bringing us back to PGE2 and its receptors," Doré said. "So we investigated whether it's possible to block the EP1 receptor so PGE2 couldn't trigger toxic effects." Doré's team first injected either the EP1 blocker ONO-8713 or the EP1 stimulator, O...
