Transcription factor Lyl-1 critical in producing early T-cell progenitors Posted: 09 Jul 2012 06:09 AM PDT A transcription factor called Lyl-1 is necessary for production of the earliest cells that can become T-cells, critical cells born in the thymus that coordinate the immune response to cancer or infections, said a consortium of researchers led by those from Baylor College of Medicine in a report in the journal Nature Immunology. read more

New chip captures power from multiple sources Posted: 09 Jul 2012 05:54 AM PDT Researchers at MIT have taken a significant step toward battery-free monitoring systems — which could ultimately be used in biomedical devices, environmental sensors in remote locations and gauges in hard-to-reach spots, among other applications. read more

Scripps Florida Scientists Show Positive Memories Linger Longer Posted: 09 Jul 2012 05:40 AM PDT If you believe positive reinforcement works better than the negative kind, a new study by scientists from the Florida campus of The Scripps Research Institute backs up your beliefs—at least in regard to fruit fly memory formation. read more

Study Finds "Mad Cow Disease" in Cattle Can Spread Widely in Autonomic Nervous System before Detectable in the Central Nervous System Posted: 09 Jul 2012 05:34 AM PDT Bovine spongiform encephalopathy (BSE, or “mad cow disease”) is a fatal disease in cattle that causes portions of the brain to turn sponge-like.  This transmissible disease is caused by the propagation of a misfolded form of protein known as a prion, rather than by a bacterium or virus.  The average time from infection to signs of illness is about 60 months. read more

Using metal complexes to modify peptide hormones Posted: 09 Jul 2012 05:06 AM PDT Researchers at the RUB and from Berkeley have used metal complexes to modify peptide hormones. In the Journal of the American Chemical Society, they report for the first time on the three-dimensional structure of the resulting metal-peptide compounds. “With this work, we have laid the molecular foundation for the development of better medicines” says Prof. Raphael Stoll from the Faculty of Chemistry and Biochemistry at the Ruhr-University. The team examined hormones that influence the sensation of pain and tumour growth. read more

Parts of Europe and the US experienced a decrease in nitrogen dioxide levels over the last 15 years Posted: 09 Jul 2012 04:53 AM PDT Satellite measurements show that nitrogen dioxide in the lower atmosphere over parts of Europe and the US has fallen over the past decade. More than 15 years of atmospheric observations have revealed trends in air quality.   As the world’s population increases, economies in many countries are also growing and populations are concentrating in large cities. With the use of fossil fuels still on the rise, pollution in large cities is also increasing. read more

Close-up of active galactic nucleus Posted: 09 Jul 2012 04:40 AM PDT A group of researchers at the Max Planck Institute for Radio Astronomy in Bonn and the Astro Space Center in Moscow, Russia, have obtained the first detection of interferometric signals between the Effelsberg 100-m telescope and the space-bound radio telescope satellite Spektr-R. The distance between the two radio telescopes is up to 350,000 kilometres – which corresponds to a virtual telescope of this aperture and an angular resolution of about 40 micro arc seconds. read more

Unprecedented Subatomic Details of Exotic Ferroelectric Nanomaterials Posted: 08 Jul 2012 06:36 PM PDT As scientists learn to manipulate little-understood nanoscale materials, they are laying the foundation for a future of more compact, efficient, and innovative devices. In research to be published online July 8 in the journal Nature Materials, scientists at the U.S. read more
