A new look at the state of the oceans

...ore than 50 other global data bases worldwide that serve as long term archives and provide information for science. PLANKTON*NET is financed in part by the European Union and has a duration of two years. Project partners include the Station Biologique de Roscoff and the University of Caen in France, the U...

Agriculture and tropical conservation: rethinking old ideas

... researchers saw evidence that the farms do indeed serve as thoroughfares for migrating animals. "These farmers actually have monkeys that come through their farms," Vandermeer said. The U-M scientists and their collaborator Jefferson Ferreira Lima of Brazil's Instituto de Pesquisas Ecologicas also spok...

Failure of 'scout cells' may lead to cancer in transplant patients

...ant patients may arise because cells that normally serve as scouts for the immune system become weakened, a new study suggests. The cancer is caused by Epstein-Barr virus (EBV), a herpesvirus that infects more than 90 percent of Americans but is ordinarily kept under control by the immune system. That c...

Natural vitamin E tocotrienol reaches blood at protective levels

...ly, tocotrienol can reach concentrations needed to serve these dual protective functions," said Chandan Sen, professor and vice chair of surgery, deputy director of the Davis Heart and Lung Research Institute at OSU, and senior author of both studies. "It is a regular dietary ingredient in Asia, so it can ...

Surprise finding for stretched DNA

...his nick, a plastic bead is attached to the DNA to serve as a "rotor" that will spin in response to torque. Magnets are used to manipulate the magnetized bead, providing a measured and highly controlled amount of tension to stretch the DNA molecule. With the use of a fluorescent coating, the subsequent sp...

The shape of life: research sheds light on how cells take shape

...so act as scaffolds, giving cells their shape, and serve as train tracks of sorts, moving important bits like chromosomes and mitochondria around inside of cells. As microtubules multiply, they form patterns that can be seen by the naked eye. The pattern is a series of waves that look a bit like zebra st...

Snakes' virtual glasses, leopard spots and all-optical transistors

...s an all-optical transistor, with the potential to serve as a building block in optical circuits and optical versions of microelectronic devices.

Meth promotes spread of virus in HIV-infected users

... His research centers on dendritic cells, which serve as the first line of defense again pathogens, and two receptors on these cells -- HIV binding/attachment receptors (DC-SIGN) and the meth-specific dopamine receptor. Dendritic cells overloaded with virus due to the action of methamphetamine can overw...

Precision biochemistry tracks DNA damage in fish

Like coal-mine canaries, fish DNA can serve as a measure of the biological impact of water and sediment pollution--or pollution clean-up. That's one of the conclusions of a new study* by researchers from the Pacific Northwest Research Institute (PNRI), Woods Hole Oceanographic Institution, the...

Links between DNA damage and breast cancer studied

... on the early stages of breast cancer and possibly serve as an early warning of a heightened risk of cancer. In the United States, breast cancer is the second leading cause of cancer-related death in women. Breast cancer detection and therapy generally target epithelial cells, the primary locus of breast...

Triple threat polymer captures and releases

... found that their materials made a perfect host to serve guest molecules. "We looked at the roughness and... into another domain. "We have these channels to serve as capillaries to take in guest molecules and hold them inside the material,," said Wooley, a membe...

Major initiative proposed to address amphibian crisis

...ovide a major control of insect pests, and in turn serve as part of the food supply for birds, fish and other animals. The demise of entire species also eliminates their possible use in biomedicine and biotechnology. One of the leading problems is a fungus that causes an infectious disease called chytri...

Corals switch skeleton material as seawater changes

...et's most diverse, Ries said. But coral reefs also serve a more practical purpose: They absorb wave energy generated by hurricanes and other severe tropical storms. "Ironically, the same factor that is likely causing such storms to increase in intensity ?global warming ?is also causing the corals to bleac...

Record air pollution above the Arctic

...in the atmosphere. They can be liquid or solid and serve as condensation nuclei during cloud formation. It .... Measurements made via the institute's aeroplanes serve the ongoing investigation of the impact of aerosols on the climate. "It is still difficult to estima...

Scientists describe new African monkey genus ?first in 83 years

...creasing the frequency of the former, will further serve to threaten this important new genus," the authors conclude. ...

Reversing 'hibernating' heart muscle focus of UB researchers

New understanding of parasite cell structures may provide treatments for serious tropical diseases

...nd they are involved with cellular energy and also serve as markers for cellular recognition. The researchers discovered a new function for these glycolipids--they are cleaved in response to cell stress caused by changes in osmotic pressure and relative acidity or alkalinity. The research by the UGA team...

Potato blight pathogenicity explained by genome plasticity

..., during development. The partial copies may also serve as alternative protein-coding units, which allow the pathogen to produce a diverse array of proteins and, consequently, to adapt to its environment. "Surprisingly, the pi3.4 gene does not code for an effector ?a small protein that elicits a defen...

Nanotubes used for first time to send signals to nerve cells

...anotubes deposited on transparent plastic can also serve as a surface on which cells can grow. And as resea...technology, these nanotube films could potentially serve as an electrical interface between living tissue and prosthetic devices or biomedical instruments. ...

More than drought affecting wheat yields

...ush said."They would be popular in this region and serve an important purpose." The problem now, he said, is any resistance breaks down in high temperatures. And not enough is known about the wheat curl mite to tellproducers when or what to spray. "There are big gaps in our knowledge," Rush said. "...
