Envisat captures first image of Sargassum from space

...l for modelling primary productivity. "The 709 band used by MERIS is not present on other ocean-colour sensors. It was essential to our detecting Sargassum," Gower said. "The MCI index has allowed us to find so many interesting things, including Sargassum and Antarctic super blooms. It really gives us...

Students invent protective pouch to enhance cell therapy

...g. The pouch is formed by sandwiching a porous band of nylon mesh between two concentric metal stents, similar to the ones used to keep clogged blood vessels open. Once the stents are in place, microcapsules filled with helpful cells are injected into the gap between the stents, where they become trap...

New technique will produce a better chromosome map

..."Our system will give an impartial estimate of the band location. It will not be researcher-dependent. It will be objective." To improve chromosome spreading, researchers use a rotary tool that vibrates the coverslip surface for several minutes. A simple mechanical vise applies up to two tons of force ...

Nanotech tools yield DNA transcription breakthrough

... same manner, Ebright notes, as winding the rubber band of a rubber-band-powered airplane stores energy. Eventually, there is sufficient energy stored in the system that the machine is able to break its interactions with the start site, to shoot forward and, at the same instant, to rewind the unwound DNA....

Slow brain waves play key role in coordinating complex activity

...rent means of detection. "By measuring high-gamma band activity, we will be able to see in real time, during surgery, how cortical regions are connected through subcortical systems, allowing us to understand how these regions process information. This hold the key to understanding diseases like autism, w...

Light guides flight of migratory birds

... of propagation. At sunrise and sunset, there is a band of intense polarized light 90 degrees from the sun...and the time of year, so does the alignment of the band of polarized light. Muheim and Phillips argue that migratory songbirds average the sunrise and su...

When the going gets tough, slime molds start synthesizing

...cterial food supply dries up, Dictyostelium amebas band together with their neighbors and form a multi-cellular tower designed to save the children. In a forthcoming study in Nature Chemical Biology, investigators at the Salk Institute for Biological Studies and the Medical Research Council of Molecular...

Attacking cancer's sweet tooth is effective strategy against tumors

...st at Merck & Co. What may excite the growing band of researchers who are studying the Warburg effect, and cancer metabolism more generally, is the way the study resolves a long-standing debate about how and why cells switch to glycolysis in the first place. Warburg speculated that cancer cells chang...

Rhinos clinging to survival in the heart of Borneo, despite poaching

...l the area where the rhinos were found. "If this band of rhinos is to have a healthy future in Borneo the poaching must be stopped immediately. Their numbers are so small that losing one or two rhinos to a poacher could upset the remaining rhinos' chances of survival," said Sybille Klenzendorf, lead bi...

Virtual microscopy project wins educational technology award

...ordinary PC screen, from any location with a broad band internet connection. The method allows free navigation in a specimen with stepless zooming, and educational annotations as well as overlay graphics to easily be added to the virtual slides. According to the researchers, all steps from processing to ...

New understanding of jet lag

...y of Virginia. Block likens GABA to a weak rubber band linking pendulums swinging at different rates. If the "rubber band" could be made stronger, such as using a drug to enhance GABA, the ventral and dorsal parts of the central timekeeper could more quickly move back into harmony. The symptoms of jet la...

Discovery clarifies role of peptide in biological clock
