How 'memory' T cells curb the spread of viruses throughout the body

...t that to protect from disease, memory CD8 T cells needed first to multiply in the lymph nodes and then migrate through the blood to kill infected cells at the site where the virus entered the body (most commonly the skin, the lungs or the gut). This process of lymphocyte multiplication and migration may t...

Dave Hamilton, a resource scientist at the Missouri Department of Conservation, said he believes there are approximately 300 black bears in Missouri, but only a few females. Th...

New findings challenge established views on human genome

...r to having all the pages of an instruction manual needed to make the human body. Researchers still must learn how to read the manuals language so they can identify every part and understand how the parts work together to contribute to health and disease. In recent years, researchers have made major stri...

UVa-led team uncovers important secret in gene replication

...eplicate, ultimately to create all of the proteins needed by a given cell. Several other researchers around the country were part of this larger project, the Encyclopedia of DNA Elements (ENCODE) project, using two preset cell lines. Overall, the consortium looked at just 1 percent of the human genome, us...

Los Alamos National Laboratory making progress in Groundwater Protection Program

...L scientists still lack detailed knowledge that is needed to predict flow paths beneath the surface, the report says. Plus, there is a lack of understanding of pathways between watersheds. LANL should add a sitewide perspective to its future groundwater monitoring plans. The laboratory also should drill ...

Pesticides choke pathway for nature to produce nitrogen for crops

...rop yields are reduced and/or more growing time is needed for these crops to reach the yields obtained by untreated crops. We feel that this is a previously unforeseen factor contributing to declining crop yields." The researchers say that field-wide experiments now are needed, in addition to tests to det...

Crucial progress in understanding Fragile X mental retardation protein

...A that encodes NXF1, which is an essential protein needed to transport most mRNAs from the nucleus to the cytoplasm of cells, said Huang. Our findings explain why the NXF1 protein level is much lower in the hippocampal neurons involved in learning and memory than in many other cells. This may suggest that ...

Reprogrammed fibroblasts identical to embryonic stem cells

...re working with tens of thousands of cells, and we needed to devise a precise method for picking out those rare cells in which the reprogramming actually worked, says Wernig. On average, it only works in about one out of 1,000 cells. To test for reprogramming, the team decided to zero in on Oct4 and anoth...

A twist of fate -- Reprogrammed fibroblasts resemble embryonic stem cells

These studies and other recent advances in strategies aimed at generating patient-specific stem cell lines are discussed in the review article...

New screening method to help find better biofuel crops
