"The new portal is the door to a treasure of data, much of it essentially inaccessible before now. Modern technologies allow us now to access these data in fa...

Not-for-profit publishers call NIH public access rule a missed opportunity

..., advances scientific research, and preserves this important relationship." "We believe the NIH rule will not achieve the goal of better access to science and will place an unreasonable burden on researchers by requiring them to pursue a duplicative submission process," said Kathleen Case, publisher for the A...

Researchers devise way to mass-produce embryonic stem cells

That's important because traditional laboratory methods used to grow these cells are costly and don't produce cells fast enough to respond to increasing demands for human embryonic stem cells, said Shang-Tian Yang, a professor of chemical and biomolecular engineering...

...ated Staphylococcus pathogens. "This could be very important to vaccine development because the PGA is present in every strain of the organism," Dr. Otto says. "If a vaccine can be developed to negate the effect of the PGA, it could be highly successful against all pathogens in which PGA is a basis for disease...

The NIH policy will achieve several important goals, including: 1. creating a stable archive of peer-reviewed research publications resulting from NIH-funded studies to ensure the permanent preservation of these vital research findings; 2. securing a searchable compendium of these resear...

Alaskan puzzles, monitoring provide insight about North Pacific salmon runs

...s include Alaska's Kvichak River, the world's most important salmon-producing river. It has had runs of more than 50 million sockeye salmon in the past, which is more valuable than all the salmon in the lower 48 combined back when those stocks were pristine. Kvichak stocks, however, have declined for a decade,...
