Probing the Effects of Light at the Atomic Scale

the effects of light at the atomic scale

By mixing a pulse of x-rays with a pulse of lower frequency optical light waves, a team of scientists at the Berkley Lab were able to measure the optical manipulation of chemical bonds at the atomic scale. Light changes matter in ways that shape our world. Photons trigger changes in proteins in the eye to […]

Scientists at the Institute of Bioengineering and Nanotechnology have developed a more powerful and longer lasting fuel cell material by replacing the central part of the catalyst with gold and copper alloy and leaving just the outer layer in platinum. Using a mixture of gold, copper and platinum nanoparticles, IBN researchers have developed a more […]

Sugar Molecules Found in Gas Surrounding Sun-Like Star

IRAS 16293-2422

Using the Atacama Large Millimeter/submillimeter Array, a team of astronomers discovered molecules of a simple form of sugar in the gas surrounding a young binary star called IRAS 16293-2422, which is located roughly 400 light-years away. A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has spotted sugar molecules in the gas surrounding […]

Pair of Eclipsing White Dwarfs Produce Gravitational Waves

J0651

Discovered last year in system J0651, two white dwarf stars are so close together that they make a complete orbit in less than 13 minutes and now astronomers have detected gravitational waves at optical wavelengths in light from them. Cambridge, Massachusetts – Gravitational waves, much like the recently discovered Higgs boson, are notoriously difficult to […]

Biologists Create Computational Model of Gene Networks

first predictive computational model of gene networks

By translating their biological knowledge into very simple Boolean statements, biologists at the California Institute of Technology have created the first predictive computational model of gene networks that control the development of sea-urchin embryos. Pasadena, California — As an animal develops from an embryo, its cells take diverse paths, eventually forming different body parts—muscles, bones, […]

NASA’s Kepler Mission Discovers Multiple Transiting Planets Orbiting Two Suns

multiple planets orbiting two suns

NASA’s Kepler mission has discovered multiple transiting planets orbiting two suns for the first time. The planets are in the Kepler-47 system, which is located 4,900 light-years from Earth in the constellation Cygnus. Coming less than a year after the announcement of the first circumbinary planet, Kepler-16b, NASA’s Kepler mission has discovered multiple transiting planets […]

Spherical Glass Amplifies Solar Energy Collection

ball-lens-prototype

Solar energy collection has had some vast improvements over the last few years; however these new prototypes from German-born, Barcelona-based architect André Broessel are quite striking since his concept uses a spherical glass to amplify the sun’s rays for electricity generation. Traditionally, solar energy collection becomes effective on vast scales, especially in solar farms, where […]

Number of Microbes Living on Earth Drastically Lower Than Previously Thought

microbes-sea-bed

The floor of the ocean is home to 2.9×1029 single-celled organisms but this large number, 10 million trillion microbes for every human on planet Earth, is only 8% of the previous estimate of  35.5×1029. Jens Kallmeyer, a geomicrobiologist and his colleagues at the University of Potsdam in Germany have created the most accurate model of […]

Using the 100-millimeter telephoto lens and the 34-millimeter wide angle lens of the Mast Camera instrument, Curiosity beamed back a new image of the base of Mount Sharp and also sent back the first planet to planet radioed words. Pasadena, California — NASA’s Mars Curiosity has debuted the first recorded human voice that traveled from […]

NASA ICESat Shows Himalayan Glaciers Have Lost Less Ice Than Worst Estimates

himalayan glaciers

A 2010 study using measurements taking by the Gravity Recovery and Climate Experiment (GRACE) satellite reported that glaciers in the Himalayas and the Tibetan plateau were shedding about 50 gigatonnes of ice per year. These results were refuted two years later by a research group using the same data but varied the interpretation to show […]

High Pyruvate Kinase Activity May Suppress Tumor Growth

boosting the activity of pyruvate kinase can prevent tumors from growing

A newly published study from MIT scientists suggests that high pyruvate kinase activity may suppress tumor growth, finding that pharmaceutical compounds that force PKM2 to be constantly on prevented tumors from growing in mice. Unlike ordinary cells, cancer cells devote most of their energy to reproducing themselves. To do this, they must trigger alternative metabolic […]

Early Intake of Antibiotics Linked to Obesity in Mice

obese-baby-mouse-mouselet

Bacteria living within the gut could have a link to obesity, possibly explaining how antibiotics fatten farm animals, and humans as well, and predispose some organisms to obesity. Researchers published their findings in the journal Nature. In the study, the scientists replicated what farmers have been doing for decades to fatten up their livestock: feeding […]
