Doppler measurements that help track storms on Earth may also be useful for understanding storms on the sun.

A Rice University astrophysicist is part of an international team that combined Doppler techniques with images and data from a space-based telescope to observe, for the first time, loops of 1,800,000-degree Fahrenheit plasma flowing up from the sun's surface at more than 12 miles per second.

Istanbul, 3 July 2012: Women who drink five or more cups of coffee a day severely reduce their chance of success from IVF treatment. Indeed, Danish investigators who followed up almost 4000 IVF and ICSI patients described the adverse impact as "comparable to the detrimental effect of smoking".

The South Pacific hurricane Tropical Depression season normally ends in April but Tropical Depression 21P has developed in the South Pacific Ocean between Papua New Guinea and the Solomon Islands from "System 91P," a low pressure area. NASA's TRMM Satellite passed over Tropical Depression 21P and captured rainfall dates and cloud heights.

TRMM is the Tropical Rainfall Measuring Mission satellite that is managed by NASA and the Japanese Space Agency, JAXA.

On July 5, NASA will launch a mission called the Solar Ultraviolet Magnetograph Investigation or SUMI, to study the intricate, constantly changing magnetic fields on the sun in a hard-to-observe area of the sun's low atmosphere called the chromosphere.

Troy, N.Y. – New research led by chemists in the Baruch '60 Center for Biochemical Solar Energy Research at Rensselaer Polytechnic Institute is seeking to detail the individual steps of highly efficient reactions that convert sunlight into chemical energy within plants and bacteria.

Amsterdam, NL, July 2, 2012 – Growing evidence suggests that Parkinson's disease (PD) often starts with non-motor symptoms that precede diagnosis by several years. In the first study to examine patterns in the quality of life of Parkinson' disease patients prior to diagnosis, researchers have documented declines in physical and mental health, pain, and emotional health beginning several years before the onset of the disease and continuing thereafter. Their results are reported in the latest issue of Journal of Parkinson's Disease.

The first images of an upward surge of the Sun's gases into quiescent coronal loops have been identified by an international team of scientists. The discovery is one more step towards understanding the origins of extreme space storms, which can destroy satellite communications and damage power grids on Earth.

If the day seems a little longer than usual on Saturday, June 30, 2012, that's because it will be. An extra second, or "leap" second, will be added at midnight to account for the fact that it is taking Earth longer and longer to complete one full turn--a day--or, technically, a solar day.

"The solar day is gradually getting longer because Earth's rotation is slowing down ever so slightly," says Daniel MacMillan of NASA's Goddard Space Flight Center in Greenbelt, Md.

DARIEN, IL – Severe sleep loss jolts the immune system into action, reflecting the same type of immediate response shown during exposure to stress, a new study reports.

Researchers in the Netherlands and United Kingdom compared the white blood cell counts of 15 healthy young men under normal and severely sleep-deprived conditions. The greatest changes were seen in the white blood cells known as granulocytes, which showed a loss of day-night rhythmicity, along with increased numbers, particularly at night.

NASA's Marshall Space Flight Center in Huntsville, Ala. is leading an international effort to develop and launch the High Resolution Coronal Imager, or Hi-C, on a sounding rocket from the White Sands Missile Range at White Sands, N.M. Hi-C is a next-generation suborbital space telescope designed to capture the highest-resolution images ever taken of the million-degree solar corona.

Tropical Storm Dokuri weakened into a tropical depression today, but NASA infrared satellite imagery is still showing some areas of strong convection and thunderstorms in the storm and they're being pushed away from the center.

Researchers using three different telescopes -- NASA's Chandra X-ray Observatory and ESA's XMM-Newton in space, and the Parkes radio telescope in Australia -- may have found the fastest moving pulsar ever seen.

The evidence for this potentially record-breaking speed comes, in part, from the features highlighted in this composite image. X-ray observations from Chandra (green) and XMM-Newton (purple) have been combined with infrared data from the 2MASS project and optical data from the Digitized Sky Survey (colored red, green and blue, but appearing in the image as white).

An international team of astronomers using data from NASA's Hubble Space Telescope has made an unparalleled observation, detecting significant changes in the atmosphere of a planet located beyond our solar system.

The scientists conclude the atmospheric variations occurred in response to a powerful eruption on the planet's host star, an event observed by NASA's Swift satellite.

NASA's TRMM satellite provided data that allowed scientists to calculate Tropical Storm Debby's rainfall totals across Florida. The highest rainfall totals from June 20-27 topped 380 mm (~15 inches) in a wide patch of central Florida from around Titusville on the east coast.

Our Milky Way may have had an encounter with a small galaxy or - more speculatively - a massive dark matter structure,perhaps as recently as 100 million years ago, and as a result of that encounter it is still 'ringing' like a bell.
