NYU algorithm enhances ability to detect cancer genes

... new algorithm computes a multipoint score for all intervals of consecutive probes, and the score reflects how well the deletion of that genomic interval may explain the cancer in these patients. In other words, the computed score measures how likely it is for a particular genomic interval to be a tumor suppre...

Study suggests evolutionary link between diet, brain size in orangutans

Wolves are suffering less from inbreeding than expected

...uctions is only required to be done at rather long intervals in order to maintain the genetic variation of populations. ...

High levels of blindness in southern Sudan following years of war

...went on for nearly half a century, with only short intervals of peace. An international team of researchers conducted a survey in May 2005 in Mankien—a district of Sudan with a total population estimated to be around 50,000. Their aim was to estimate how many people were blind or had ‘‘low vision’?and to f...

Evolution of Old World fruit flies on three continents mirrors climate change

...so looked at shifts in weather patterns during the intervals between sample collections. At nearly all sites, t... a warming climate. However, organisms with longer intervals between new generations, humans or sequoia trees for example, probably can't adapt nearly as readily...

The great escape -- fleeing fish fall in line

...he experiment was performed ten times at 10 minute intervals on a total of seven separate schools of grey mullet. Interestingly, results suggested that there is a trend for individual fish to maintain a given rank, indicating that the chronological order of escape responses within a school is maintained in su...

Scientists unravel clue in cortisol production

...led on the DNA, they tested the cells at different intervals in order to get a snapshot of which proteins were interacting, both with each other and the DNA and in which order this occurred. Then they mutated the proteins to stop them from fulfilling their roles. "One of the best ways to try and figure out ...

Experimental vaccine given during pregnancy reduces stillbirths from common virus

...the study were vaccinated three times at two-month intervals before they became pregnant and were injected with the guinea pig form of CMV early in their third trimester. Tests showed that the rodents given the experimental vaccine had acquired immunity to guinea pig CMV because they produced antibodies to ...

Selective marker found to indicate aggressive form of breast cancer

...ommonly detected during normal screening mammogram intervals than other screening subtypes, which likely reflects its aggressive nature. These important clinical correlations likely explain why this subtype disproportionately accounts for breast cancer mortality, according to DiRenzo. In a retrospective ...

Trusting your instincts leads you to the right answer

...al display screen was switched off at various time intervals either before or after the subjects' eyes landed on the target. When the on-screen image was hidden immediately after the subjects' eyes had landed on the target, the subjects often believed they were just guessing where the odd one out was. They wer...
