Priming embryonic stem cells to fulfill their promise

...ure of almostall tissues. Bhatia, Chien, and Flaim focused on just one - theextracellular matrix."We kept the other factors constant and developed a miniaturizedtechnique to precisely vary extracellular matrix proteins as a way toidentify which combinations were optimal in producing differentiatedcells from ...

Elusive HIV shape change revealed; Key clue to how virus infects cells

...tigator Stephen Harrison, PhD, and Bing Chen, PhD, focused on the gp120 protein, part of HIV's outer membrane, or envelope. gp120's job is to recognize and bind to the so-called CD4 receptor on the surface of the cell HIV wants to infect. Once it binds, gp120 undergoes a shape change, which signals a compani...

Research advances quest for HIV-1 vaccine

... Neutralizing Antibody Consortium (IAVI), which is focused on understanding broadly neutralizing antibodies at the molecular level and transferring this knowledge into the design of vaccines capable of stimulating broadly neutralizing antibodies against globally diverse HIV. According to Dr. Wayne Koff, IAVI...

Whole genome fine map of rice completed

...rid Rice Genome Project, initiated by BGI in 2000, focused on the hybrid rice "Liang You Pei Jiu" as the basic research object. The hybrid was developed by the famous rice expert Yuan Longping. The goal of the project was to reveal the molecular mechanism of the hybridization advantages, thus providing the t...

U-M scientist to talk about tissue engineering at AAAS

.... Many researchers at University of Michigan have focused their tissue engineering efforts on the head and neck, in part because U-M Dentistry plays a leading role in the effort. Dentists have a long tradition of finding ways to fill tooth cavities that will not heal on their own, Krebsbach said, and that h...

Forexample, we have integrated the Protein Biomarker Package into thelatest versions of the products (previously the Protein BiomarkerPackage requi...

The secret lives of whales

...The Navy had heard the whales for years but hadn’t focused on the significance of their low voices. To me it was like —ohmygawd!?/p> Access to the U.S. Navy’s underwater listening systems took researchers from fixed-point observations such as ships, to synoptic views of the ocean. Clark can move a cursor...

ASU researchers finds novel chemistry at work to provide parrot's vibrant red colors

...t makes the colors of the birds possible, and then focused on "deconstructing the color into its component parts." McGraw said an interesting aspect of the five polyenal lipochromes that provide the red in parrots, is that the pigment is found only in the bird's feathers and nowhere else in the body of the ...

Researchers trace evolution to relatively simple genetic changes

..., Kingsley and graduate student Pamela F. Colosimo focused on a well-studied little fish called the stickleback. The fish -- with three bony spines poking up from their backs -- live both in the seas and in coastal fresh water habitats all around the northern hemisphere. Sticklebacks are enormously varied, ...
