Novel biotoxin being studied for use in opioid withdrawal

...is derived from the puffer fish, also known as the blow fish. Studies have shown it to be fast acting, long lasting and non-addictive. It was originally developed for the clinical treatment of heroin withdrawal in China. It works by blocking slow sodium channel nocicipetive pain fibres in a highly selecti...

...trong seasonal pattern caused by strong winds that blow through the Panama Canal Zone in winter. The winds mix nutrients from deeper waters to the surface, and the nutrients promote phytoplankton growth.

The secret life of acid dust

...spheric models. "Calcite-containing dust particles blow into the air and encounter gaseous nitric acid in polluted air from factories to form an entirely new particle of calcium nitrate," said Alexander Laskin, a senior research scientist at the Department of Energy's Pacific Northwest National Laboratory...

Growth in the sea comes down to a struggle for iron

...to grow as readily. Since prevailing winds tend to blow iron rich dust off the Asian continent into the Pacific, it may be that phytoplankton closer to the source of that dust may be primed to respond differently. Wells and his colleagues will be studying the possibility that small variations in iron thr...

An (ecological) origin of species for tropical reef fish

Thisdifference in pressure causes winds to blow from the Southwest ArabianSea bringing annual rainfall to the subcontinent from June to September.In the Western Arabian Sea, these winds also cause upwelling of coolernutrient-rich water, creating ideal conditions for phytoplankton tobloom every yea...

A decade after launch, ERS-2's mission continues

...mission. Back in 2001 the spacecraft was struck a blow as the last of its pointing gyroscopes failed. However all instruments were still functioning perfectly, so ESA engineers worked with industry to develop a new 'gyro-less' working mode to resume data delivery. Then in June 2003 the onboard Low Bit R...

Balaji Panchapakesan, assistant professor of electrical and computer engineering at UD, has recently reported on the discoveries in the journals NanoBiotechnology and Oncology Issues. Panchapakesan said this is basic resear...

New and sharper X-rays of cell's ribosome could lead to better antibiotics

..., the repulsion of the RNA's negative charge would blow the ribosome apart. Some of the magnesium ions form a salty liquid at the interface between the large and small subunits of the ribosome, perhaps lubricating the machine. These and other hypotheses need further exploration, he said. "All the interact...

Edinburgh vet's bid to cut deaths from rabies in Africa

Damaged Iraq marshes show renewed signs of life

...hat some of the remaining inhabitants had begun to blow up the dikes and dams. As a result, portions of the marshes had reflooded, and some native plants were beginning to re-establish themselves in the restored areas, Richardson said. "That was good news," he said.

Attacking cancer's sweet tooth is effective strategy against tumors

...ing out the glycolytic pathway could deliver a big blow to tumor cells. "LDHA could be one weak point that we could attack but maybe, if we understand exactly all the steps involved, we could devise alternative strategies to attack the same pathway," Fantin said. What makes the prospect of anti-glycolytic...
