Bursts of waves drive immune system 'soldiers' toward invaders

... Weiner. "Evolution has found the same solution to generating waves again and again even with completely different molecules, and at different scales of space and time -- encouraging for those of us who want to uncover general organizing principles in biology." Weiner is an investigator in both the UCSF Card...

Carnegie Mellon's Peter Adams receives EPA research grant

...s announced intentions to build as many as 150 new generating plants fueled by coal, adding to the 645 units that produce about half the nations electricity. But these coal-fired electric plants collectively account for 67 percent of all the sulfur dioxide emissions in the U.S., which is a major precursor of pa...

Scientists prove that disputed Korean stem cell line comes from an unfertilized egg and not cloning

... pES cells, parthenogenesis is an efficient way of generating embryos and that it may someday be feasible to generate patient-specific pES cells from females. If careful genetic and functional analysis of tissues derived from human pES cells show them to be safe and effective, then pES cells might represent a f...

Discredited Korean embryonic stem cells' true origins revealed

...ntly demonstrated in mice a feasible technique for generating parthenogenetic embryonic stem cells that were genetically matched to the egg donor at the genes that control tissue typing, and are attempting to create similar cells from humans.

Cost-effective method for gene silencing is featured in Cold Spring Harbor Protocols

...roblem; it describes a cost-effective approach for generating silencing RNAs, called esiRNAs, to efficiently target virtually any gene in mammalian cells. The protocol ( http://www.cshprotocols.org/cgi/content/full/2007/16/pdb.prot4824 ) describes how to enzymatically generate RNA molecules in vitro, using th...

Air pollution link to clogged arteries

...rocarbons and transition metals inflame airways by generating reactive oxygen species and oxidative stress when combined with oxidised phospholipids in the arteries. This can lead to vascular inflammation, which can in turn lead to increased lesions in the clogged arteries, potentially giving rise to blood clot...

Monell researchers find metabolic defect in liver that can lead to obesity

...ce inside mitochondria, the cells power plants for generating energy. If the ability to oxidize fat is impaired, the bodys capacity to make energy is reduced. This leads to increased hunger and overeating, as the body tries to increase the amount of energy available to meet its needs. When the diet is l...

But scientists are reporting a stride in that direction in the August 8 issue of ACS Nano Letters , a monthly journal, with development a more...

Tracing Parkinson's lethal mechanism

...are produced inside mitochondria in the process of generating energy for the cell. Specifically, the researchers found that treating neurons with MPTP activates Cdk5 to switch off Prx2. Whats more, they found that activating Prx2 in MPTP-treated mice prevented the loss of dopamine-producing neurons. And they ...

Marine worm opens new window on early cell development

Platynereis dumerilii, the researchers wrote, appears to have retained ancestral morphological and genomic features, including a slowly evolving protein complement, and, therefore, can be considered a living fossil....

Alzheimer's drug based on Purdue -- designed inhibitor begins clinical trials

...6 at various doses. The company expects to begin generating human clinical data by the end of 2007 and to begin phase II studies in Alzheimer's patients in 2008. The drug could be administered at any stage of the disease, Ghosh said. These clinical trial phases are the first steps in a lengthy process neces...

If we selectively blocked the EPCs, tumors were unable to make blood vessels and could not sustain their own growth, said Vivek Mittal, CSHL Assistant Professor. The findings open an entirely new field of r...
