Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

...iseases such as cancer. "Each type of cell in our bodies contains the same genes. What makes them do different things involves which genes are turned on," notes Bradley Bernstein, a pathologist at Harvard Medical School. He is also a research associate at the Broad Institute of Harvard and M.I.T., where a ...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

Falling ants glide back to trunk to avoid dangers of forest floor

...established that the ants basically reorient their bodies so their hind legs and abdomen point toward the tree, and use their head-up fall through the air to take them feet-first toward the trunk. How they land is still a mystery, but evidently claws on their back legs act like grappling hooks to snag the t...

BioMed Central welcomes the new National Institutes of Health public access policy

...BioMed Central anticipates that many other funding bodies worldwide will now follow the example set by NIH. All NIH grantees now have a new factor to take into account when choosing where they wish to publish their research. To fulfil the NIH request, authors publishing with most of the traditional subscri...

Marburg haemorrhagic fever in Angola update

Very few patients with laboratory-confirmed Marburg haemorrhagic fever have survived; most hospitalized patients have died within a day...

It's what allows our core temperature to stay at 98.6 degrees, regardless of whether we're in Alaska or Tahiti," Roth said. In addition to mice, Roth and colleagues in previously published work have ...

One gene links newborn neurons with those that die in diseases such as Alzheimer's

...eurons project. The dyes then traveled back to the bodies of the cells in the high vocal center. As a result, replaceable and nonreplaceable neurons could easily be distinguished under the microscope. Then, looking at very thin slices of brain tissue, the researchers used a technique called laser capture m...

The lopsided brain: Attention bias is shared by humans and birds

The experiment is similar in concept to those that reveal pseudoneglect in humans--so-called cancellation tasks in which subjec...

Too much water may be as dangerous as too little during long-distance athletic events
