Grass makes environmentally friendly biofuel

... And even though the ratio of the amount of energy needed to produce grass pellets to the amount of energy they produce is much more favorable than for other biomass crops, the lack of government support prevents the industry from going forward, he says. Cherney has made a comparison of wood pellets with v...

New understanding of cell movement may yield ways to brake cancer's spread

.... Guided by this fragment, the molecular machinery needed for cell movement begins accumulating at the leading edge, or front of a cell in response to a variety of chemical messengers, and begins the directed process of migration. The study, led by associate professor and Burnham Cancer Center Acting Direct...

Cancer related gene p53 not regulated as indicated by previous tissue culture research

...s present and was stable and fully functional when needed to halt the cycle cell to repair DNA damage or to induce apoptosis. "It came as a complete surprise. We even used a system that would have allowed us to switch on the modified p53 protein at will because we feared that the mice might not be viable a...

UN: World in big ecological mess

...n eliminating hunger, but at far slower rates than needed to halve the scourge by 2015. Changes in ecosystems such as deforestation influence the abundance of human pathogens such as malaria and cholera, as well as the risk of emergence of new diseases. Malaria, for example, accounts for 11 per cent of the ...

UN pours polio vaccine into Yemen amid outbreak

...the US Centers for Disease Control and Prevention, needed $50 million by July and $200 million for 2006, it added. UNICEF said polio has been losing its grip even on the exporting "reservoirs of transmission" -- northern Nigeria, northern India and Pakistan, with India reporting only 14 cases so far this y...

Recombinant DNA technology may enable oral, rather than injectable, delivery of protein drugs

... during chemotherapy. After that, the researchers needed to bring transferrin and G-CSF together, a process that is detailed in the PNAS paper. "Through recombinant DNA technology, we combined the genetic codes for both human transferrin and G-CSF to create a new recombinant DNA, which, when expressed in a...

Combination therapy leads to partial recovery from spinal cord injury in rats

...studies showing that a combination of therapies is needed for successful spinal repair, in this case, specialized cells and growth factors. The experiments also used a combination of outcomes -- physiology, behavior, and anatomy -- to point clearly at myelination as the cause for improved function," says Na...

Improved statistical tools reveal many linked loci

... bypasses the previously overwhelming computations needed to puzzle together the myriad elements that influence gene expression throughout an entire genome. And unlike earlier approaches to understanding how multiple loci interact, the new technique can distinguish between a group of genes with a linked sub...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

...n enemy had arrived, Dangl said. Instead, they are needed to form an even earlier disease surveillance antenna or hair trigger. When disease invaders pull that trigger, infected plants cells quickly commit suicide, often preventing the invader from destroying the entire plant. The new discovery appears to ...

It's electric: Cows show promise as powerplants

...olts of electricity. That's about half the voltage needed to run one rechargeable AA-sized battery, said Ann Christy, a study co-author and an associate professor of food, agricultural and biological engineering at Ohio State University. While rumen fluid itself won't be used as an energy source, some of t...

Wearing and her colleagues found that many off-the-shelf models used in infection management do not realistically account for the length of time that people harbor infections. The simplest models entirely ignore the...

Newly discovered genetic disease sheds light on body's water balance

Gitelman and a team of fellow pediatrician scientists at UCSF took their findings about the two patients to the laboratory, working with colleagues to isolate the genetic mutations responsible for their disruption in water bala...

Purdue scientists may have found key to halting spinal cord damage

When a person inhales smog or tobacco smoke, for example, the fluids lining the respiratory tract show an acrolein concentration of about a millimole - not much by measuring-cup standards, but still over 1,000 times more than usual. ...
