Researchers examine carbon capture and storage to combat global warming

...ently, three industrial-scale projects are pumping millions of tons of carbon dioxide into the ground every year. Two of them represent the first efforts at storage in deep saline aquifers. A Stanford team also has begun researching storage of carbon dioxide in deep coal beds. In coal, chemical bonds form ...

Exploring the dark matter of the genome

...omeres, adding up to hundreds of thousands or even millions of bases in length. In these "seas" of satellite DNA there are "islands" of moderate-length repeats totaling only tens or hundreds of kilobases, made up of transposons or fragments of transposons. In other regions of heterochromatin, the transpos...

UCF nanoparticle offers promise for treating glaucoma

Turn-ons and turn-offs for neurons

...ime we think and experience, touch, smell or fear, millions of neurons in our brain becomes active. These nerve cells communicate with each other by chemical and electrical impulses to compute incoming sensory information and integrate it via distinct brain regions.

How plague-causing bacteria disarm host defense

...arro said. "But Yersinia has maintained YpkA over millions of years, so it must be doing something important." The researchers speculate that YpkA plays an important role in disabling the body's immune system beyond its previously known role of disrupting the host cell's normal structure, which interferes w...

Avian influenza survivors' antibodies effective at neutralising H5N1 strain

...N1 influenza virus has caused disease and death in millions of poultry across the globe and occasionally has been transmitted to humans, often fatally. By mid-May 2007, according to the World Health Organization, there had been 306 known cases in humans, 185 of them fatal. Now, doctors based at the Hospit...

For many insects, winter survival is in the genes
