When astronomers study protoplanetary disks of gas and dust that surround young stars, they sometimes spot a dark gap like the Cassini division in Saturn's rings. It has been suggested that any gap must be caused by an unseen planet that formed in the disk and carved out material from its surroundings. However, new research shows that a gap could be a sort of cosmic illusion and not the sign of a hidden planet after all.

If you are planning to take the long trip to Mars, don't forget to pack sleeping pills and skin cream. A new study published in the November 2015 issue of The FASEB Journal, is the first-ever examination of the medications used by astronauts on long-duration missions to the International Space Station.
The deadly Ebola virus outbreak in West Africa also took its toll socially on one of the fastest growing populations in the United States, African immigrants. Guy-Lucien Whembolua, a University of Cincinnati assistant professor of Africana studies, leads an analysis of national news coverage of the Ebola scare in a poster presentation on Nov. 2, at the 143rd American Public Health Association (APHA) Annual Meeting and Expo, in Chicago.
Boulder, CO, USA - While Mars doesn't have much in the way of Earth-like weather, it does evidently share one kind of weird meteorology: acid fog.
We all pursue goals. It stands to reason that we meet our goals better when we pursue them consciously. But is that really the case? Perhaps not, according to a forthcoming study in the Journal of Marketing Research. As the study shows, unconscious goal pursuit can be just as beneficial.
Pressing on the gas and the brakes at the same time hardly sounds like good driving technique, but Weizmann Institute scientists have discovered that plants drive some of their key processes in precisely such manner.
Münster classical scholars discovered invaluable ancient Syrian mosaics and buildings and are excavating one of the few sites that are currently accessible for studies on ancient Roman Syria despite the tense political situation in the Middle East. "The ancient city of Doliche, which was part of the province of Syria in Roman times, lies at the fringes of the Turkish metropolis of Gaziantep today", explains Prof. Dr. Engelbert Winter from University of Münster's Cluster of Excellence "Religion and Politics".
Osteoporosis is one of the chief reasons why the elderly often suffer broken bones from relatively minor injuries. Postmenopausal women in particular experience a relatively rapid loss in bone mass due to a reduced concentration of oestrogen, which is responsible for strong bone growth during youth. Maintaining bone mass requires physical exercise and vitamin D, which is mainly produced in the skin with the help of UVB radiation. This is why, especially in the wintertime, many elderly women are prescribed a vitamin D supplement by their doctor to maintain bone mass.
The Soft X-ray focusing Telescope (SXT) onboard Astrosat, India's first satellite dedicated to astronomical observations, saw its first light from an astronomical source on Oct. 26, 2015, after the camera door was opened at 06:30UT. The telescope door covering the optics had already been opened 10 days earlier.
BLOOMINGTON, Ind. -- While the contributions and value added by star performers can be extraordinary and even legendary, companies today often overlook the influence those top employees can have on others around them, according to new and previous research by an Indiana University Kelley School of Business management professor.
Writing in the journal Organizational Dynamics, Herman Aguinis, the John F. Mee Chair of Management and professor of organizational behavior and human resources, discusses how companies can effectively produce and manage star performers.
A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.
The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change's (IPCC) 2013 report, which says that Antarctica is overall losing land ice.
HANOVER, N.H. - For millennia, Greenland's ice sheet reflected sunlight back into space, but satellite measurements in recent years suggest the bright surface is darkening, causing solar heat to be absorbed and surface melting to accelerate. Some studies suggest this "dirty ice" or "dark snow" is caused by fallout from fossil fuel pollution and forest fires.
NASA satellites have been providing data on powerful Tropical Cyclone Chapala as it continued strengthening in the Arabian Sea. The Global Precipitation Measurement Mission or GPM core satellite provided a look at strengthening Tropical Cyclone Chapala in the Arabian Sea. Additionally, NASA's Aqua satellite got a good look at the storm's small eye.
A team of astronomers is proposing that huge spiral patterns seen around some newborn stars, merely a few million years old (about one percent our sun's age), may be evidence for the presence of giant unseen planets. This idea not only opens the door to a new method of planet detection, but also could offer a look into the early formative years of planet birth.
Lab-based estimates of how worker productivity rubs off on peers are very similar to results from the field, a new report shows. The results come amid debate over the extent to which insights from lab experiments in the social sciences can be generalized to the field setting. Scientists debate the generalizability of lab findings in the social sciences for numerous reasons. Among them, they cite subjects tending to be students (and thus not representative of real world populations), and the controlled setting of lab studies, artificial in relation to actual workplaces.
