Hinode satellite captures X-ray footage of solar eclipse

The XRT collects X-rays emitted from the sun's corona - the hot, tenuous outer layer that extends from the sun's visible surface into the inner solar system. Gas in the solar corona reaches temperatures of millions of degrees. The energy source that heats the corona is a puzzle. The sun's surface is only 10,000 degrees Fahrenheit, while the corona is more than 100 times hotter.

NASA identifies ice cloud above cruising altitude on Titan

NASA identifies ice cloud above cruising altitude on Titan

NASA scientists have identified an unexpected high-altitude methane ice cloud on Saturn's moon Titan that is similar to exotic clouds found far above Earth's poles.

This lofty cloud, imaged by NASA's Cassini spacecraft, was part of the winter cap of condensation over Titan's north pole. Now, eight years after spotting this mysterious bit of atmospheric fluff, researchers have determined that it contains methane ice, which produces a much denser cloud than the ethane ice previously identified there.

New hope for drug discovery in African sleeping sickness

New hope for drug discovery in African sleeping sickness

In early drug discovery, you need a starting point, says North­eastern Uni­ver­sity asso­ciate pro­fessor of chem­istry and chemical biology Michael Pollastri.

In a new research paper published Thursday in the journal PLOS Neglected Tropical Diseases, Pollastri and his colleagues present hun­dreds of such starting points for poten­tially treating African sleeping sick­ness, a deadly disease that claims thousands of lives annually.

NASA sees Tropical Storm Ana still vigorous

NASA sees Tropical Storm Ana still vigorous

NASA's TRMM satellite saw that Tropical Storm Ana was still generating moderate rainfall is it pulled away from Hawaii. The next day, NASA's Aqua satellite saw that wind shear was having an effect on the storm as it moved over open ocean.

On Oct. 24, Ana had moved far enough away from land areas that there were no watches or warnings in effect.

NASA HS3 mission Global Hawk's bullseye in Hurricane Edouard

NASA's Hurricane Severe Storms Sentinel or HS3 mission flew the unmanned Global Hawk aircraft on two missions between Sept. 11 and 15 into Hurricane Edouard and scored a bullseye by gathering information in the eye of the strengthening storm. Scientists saw how upper-level wind shear was affecting Edouard on the HS3's Global Hawk flight of the 2014 campaign over Sept. 11 and 12, and saw the hurricane strengthen during the sixth flight on Sept. 15 and 16.

TSRI chemists achieve new technique with profound implications for drug development

TSRI chemists achieve new technique with profound implications for drug development

LA JOLLA, CA – October 23, 2014 - Breaking carbon-hydrogen (C-H) bonds to alter existing molecules to create new ones is an increasingly important avenue for drug development. Of particular interest is mirror-image or "one-handed" compounds, but C-H breaking methods for making pure batches of these molecules have worked with only a limited range of starting materials.

NASA's Terra satellite shows a more organized Tropical Storm Ana

NASA's Terra satellite shows a more organized Tropical Storm Ana

The strong southwesterly wind shear that has been battering Tropical Storm Ana has abated and has given the storm a chance to re-organize. Ana appeared more rounded on imagery from NASA's Terra satellite as thunderstorms again circled the low-level center.

Startups should seek quality -- not quantity -- in partnerships, study finds

BUFFALO, N.Y. -- When partnering with larger companies, startups with a small number of carefully chosen alliances will reap the most benefits, according to new research from the University at Buffalo School of Management.

Pre-enlistment mental disorders and suicidality among new US Army soldiers

Two new studies suggest that while individuals enrolling in the armed forces do not share the exact psychological profile as socio-demographically comparable civilians, they are more similar than previously thought.

Sunshine may slow weight gain and diabetes onset, study suggests

Exposure to moderate amounts of sunshine may slow the development of obesity and diabetes, a study suggests.

Scientists who looked at the effect of sunlight on mice say further research will be needed to confirm whether it has the same effect on people.

The researchers showed that shining UV light at overfed mice slowed their weight gain. The mice displayed fewer of the warning signs linked to diabetes, such as abnormal glucose levels and resistance to insulin.
