Microscopes at microscopic size

...ps no larger than a single cell that could lead to faster development of new drugs and quicker medical tests. The research team moved away from the idea that a microscope is something you have to look through to create optical biochips onto which scientists can place biological samples. Special fluorescent...

Finding hidden invaders in a Hawaiian rain forest

... nitrogen," commented Asner. "The leaves turn over faster and there is more nitrogen in the soil. However, the invader shades out nearly all other species, so this excess nitrogen is not available to other species. Although we don't know exactly what the domino effects of this invasion will be, we are in a ...

Infants with Rare Genetic Disease Saved By Cord Blood Stem Cells

...zberg. Cord blood appears to provide a better and faster correction of enzyme deficiencies than does adult bone marrow, she said. Stem cells from cord blood travel to the brain more rapidly than stem cells from adult bone marrow, and cord blood stem cells repair deficiencies in both the central and periphe...

Product improves peptide identification for proteomics research

...lection of mass spectra at rates up to three times faster than its predecessors. "The combination of the new LC/MSD Trap XCT Ultra with Agilent's breakthrough HPLC-Chip/MS technology will set a new standard for protein identification and analytical performance," said Ken Imatani, product marketing manager ...

Computational Method Speeds Mapping of Cell Signaling Networks

... are working on new approaches to make the process faster and easier. One such group, led by Garry Nolan of Stanford University and Douglas Lauffenburger of MIT has "opened the door for systematic mapping of signaling pathways," according to team member Dana Pe'er. They tested their technique--a combined a...

HIV-1 spread through six transmission lines in the UK

...transmission chain identified by the study shows a faster doubling time in 2003 than the other five. Current surveillance data shows a recent increase in infections amongst homosexual men in the UK , which may partly have come through this chain. Dr Deenan Pillay of UCL's Centre for Virology says: “Our stu...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

Increased risk of osteoporosis associated with gene that one in five people have

... gene produces an enzyme that breaks down estrogen faster than usual, leading to low serum estrogen levels and high levels of estrogen metabolites," Villareal says. "Low levels of estrogen put a woman at risk for osteoporosis, and our data showed a strong correlation between the genetic variant and low bone...

Institute for Systems Biology Symposium Addresses Need for Better Computational Tools

...ientific and medical breakthroughs come at an ever faster pace-certainly more rapidly than in any new field of biology in the 20th Century. Annotating these proteins of unknown function remains a critical bottleneck for systems biology and is crucial to understanding the biological relevance of genome-wide ...

NASA links nanobacteria to kidney stones and other diseases

...y environment, NB was found to multiply five times faster compared to normal gravity on Earth, supporting earlier discoveries that microbes have radically different behavior in weightless environments. NB is also shown to possibly be an infectious risk for crew members living in close quarters. "The concep...

Wisconsin researchers identify sleep gene

...by EEG. The waves are slower during deep sleep and faster during waking times. One way of getting from the faster to the slower state is by opening ion channels, allowing potassium to flow through them. "Our hypot...

Cricket's finicky mating behavior boosts biodiversity

... 4.17 every 1 million years, or more than 10 times faster than the average speciation rate for invertebrates. This rapid evolution is contributing to an "explosion" of new cricket species, especially on Hawaii, the largest and youngest island in the Hawaiian archipelago, say the two scientists. Some 38 diff...

Vampire bats keep out of trouble by running

It remains unclear exactly what the native prey were before the introduction of cattle, he adds. The Cornel...

Supercomputer Dedicated To Bioengineering, Computational Biology Installed

"It's not new that science has been developing large computational challenges, but what is new is the commoditization of superc...

In the migratory marathon, parasitized monarchs drop out early

These results, published in the March issue of Ecology Letters, could explain why parasite infections are much lower in migratory monarch populations compared to year-round residents that do not m...

Same mutation aided evolution in many fish species, Stanford study finds

...sley noted that the unarmored fish are lighter and faster than their more burdened marine cousins. In an effort to learn more about how the armor trait evolves so quickly, Kingsley and his colleagues sequenced that genetic region in a large number of marine fish, all of which had a complete set of armor pl...
