... cytoplasmic membrane. Focal adhesions are regions rich with receptors for growth factors and they are also structural attachment points that link the extracellular world to the protein filaments and tubes that comprise a cell’s internal cytoskeleton. While researchers showed that paxillin serves as a...

Modeling the restless brain

... state is not time-invariant, but instead contains rich and interrelated temporal structure at multiple time scales that is shaped by the underlying structural topology," Sporns and Honey wrote in an article appearing this week in the Proceedings of the National Academy of Sciences early edition online. ...

Exploring the dark matter of the genome

In nature, proteins sweep up nanoparticles

...aboratory. The research team analyzed a biofilm rich in zinc sulfide that was collected from the water-filled mine. The sulfide is a metabolic waste product of bacteria that thrive in the oxygen-free mine. Once the sulfide is released into the watery environment, it readily combines with metals, in thi...

A first -- Hebrew University scientist observes brain cell development in 'real time'

Adult stem cells from human cord umbilical cord blood successfully engineered to make insulin

...n umbilical cord blood because it is an especially rich source of fresh adult stem cells and is easily available from donors undergoing Caesarian section deliveries in UTMB hospitals. "However," he added, "embryonic stem cell research was absolutely necessary to teach us how to do this." Embryonic s...

Invasion of the island bats

...inent, it seemed only logical that continents were rich sources from which islands drew only a small sample. Once isolated and with fewer species around, island organisms were thought to lose their competitive edge and so they hardly ever re-colonized the continent from which they originated. These vi...

Scientists discover new life in the Antarctic deep sea

...ss is in fact a dynamic, variable and biologically rich environment. Finding this extraordinary treasure trove of marine life is our first step to understanding the complex relationships between the deep ocean and distribution of marine life." Three research expeditions, as part of the ANDEEP project ...

No magic tomato? Study breaks link between lycopene and prostate cancer prevention

... work." Previous studies suggested that a diet rich in lycopene protected against prostate cancer, spurring commercial and public interest in the antioxidant. Antioxidants protect against free radicals, highly reactive atoms and molecules that can damage DNA and other important molecules in the cell. ...

In young mice, gregariousness seems to reside in the genes

The level of social interplay of the two strains of mice, Panksepp and Lahvis note, is mirrored in their vocalizations, and the differences in vocalization between the two ...

...f the world's most important bioregions, harboring rich array of plant and animal species and offering a wealth of goods and services to society. For years, ecological science has shown how large scale forest clearings cause declines in biodiversity and the availability of forest products. Yet some impor...

ConocoPhillips establishes $22.5M biofuels research program at Iowa State

... its central location in the agricultural belt and rich traditions of research and service, is uniquely positioned to set the standard for biorenewables research, education and technology transfer," Geoffroy said. "Contributing to the development of the bioeconomy is directly in line with our mission: 'Cr...

A genetic 'gang of 4' drives spread of breast cancer

The unlikely pairing of cholesterol-l...

Boosting brain power -- with chocolate

... Macdonald found that consumption of a cocoa drink rich in flavanols ?a key ingredient of dark chocolate ?boosts blood flow to key areas of the brain for two to three hours. Increased blood flow to these areas of the brain may help to increase performance in specific tasks and boost general alertness o...
