Massive gene screening points way to more effective chemotherapy

...LAS April 11, 2007 -- Using a technology that can quickly screen all 20,000-plus human genes for biological activity, scientists have isolated 87 genes that seem to affect how sensitive human cancer cells are to certain chemotherapy drugs. In a study available online and appearing in the April 12 edition ...

Disease can be our ally, not just our enemy, says new book by UCR evolutionary biologist

...their body temperatures through fever recover more quickly than those given fever-reducing drugs. Children in particular are given fever reducers far more often than necessary. On the other hand, sneezing and sniffling likely helps the organism that causes them to spread, so reducing their frequency probab...

Need oxygen? Cells know how to spend and save

... oxygen," Semenza says, "so it's vital for them to quickly react to slight changes in oxygen levels." The protein-swap is how they do it. In the mitochondria, the tiny powerhouses found in every cell, energy is produced by passing electrons through a series of relay stations called cytochromes until they ...

First impressions: Computer model behaves like humans on visual categorization task

... subjects see an image flashed on a screen that is quickly replaced with an erasing mask (pink noise), which is presumed to shut down cognitive feedback. After just a 50 milliseconds glimpse of an image, less than the time it takes to flash two video frames, people can still accurately report an object's cat...

Genomic test could help detect radioactivity exposure from terrorist attacks

Scientists at Duke University Medical Center have developed a new blood test to rapidly detect levels of radiation exposure so that potentially life-saving treatments could ...

Elephant highways of death

... The authors note, however, that logging roads are quickly eating into this last great elephant territory. Even in war-torn Democratic Republic of Congo, protected areas are proving to be the last strongholds for elephants, despite decades of poaching. The study is the first major scientific survey of fores...

The great escape -- fleeing fish fall in line

...escape at once in the desperate hurry to escape as quickly as possible. However, new research indicates that this is not the case, and in fact fish in schools escape using a relatively fixed chronological order. This research was carried out at the International Marine Centre (IMC) in Sardinia, Italy, and w...
