Tiny Tropical Storm Michael formed today, Sept. 4, from the thirteenth tropical depression in the Atlantic Ocean, but it seems that wind shear will make Michael struggle to intensify over the next couple of days like his "sister" Tropical Storm Leslie. Isaac's remnants blanket the U.S. east coast.

Tropical Storm John had about one day of fame in the Eastern Pacific. Born Tropical Depression 10, it intensified into Tropical Storm John on Sept. 2 at 5 a.m. EDT and maintained maximum sustained winds of 40 mph (65 kmh) until it weakened back into a depression on Monday, Sept. 3 at 11 p.m. EDT.

Over the weekend of Aug. 31 to Sept. 2, Tropical Storm Leslie's maximum sustained winds were pretty constant and satellite imagery from NASA's Aqua and Terra satellites confirm the steadiness of the storm. That story is expected to change later this week however, as Leslie nears Bermuda and is expected to reach hurricane strength. Meanwhile, Leslie is still about the same strength today, Sept. 4 because of wind shear.

Irvine, Calif., Sept. 4, 2012 – Repeated exposure to violent images from the terrorist attacks of Sept ember 11 and the Iraq War led to an increase in physical and psychological ailments in a nationally representative sample of U.S. adults, according to a new UC Irvine study.

The Earth and the planets of our solar system are not alone in the universe. Over the past few decades, the hunt for extrasolar planets has yielded incredible discoveries, and now planetary researchers have a new tool—simulated models of how planets are born.

Most planets form when a molecular cloud collapses into a young star. The leftover gas and dust form a disk around the star, and the particulates inside the disk begin to collide and coalesce over millions of years, forming larger and larger objects until a planet eventually takes shape.

Almost three quarters of disposed electrical household appliances in Spain are processed out of the Integrated Waste Management System (SIG). A study at the University of Salamanca exposes how many manufacturers are not registered in the established waste management system and avoid payment.

(Washington, DC) – Languages are continually changing, not just words but also grammar. A recent study examines how such changes happen and what the changes can tell us about how speakers' grammars work. The study, "The course of actualization", to be published in the September 2012 issue of the scholarly journal Language, is authored by Hendrik De Smet of the University of Leuven /Research Foundation Flanders.

Plastic optical fibres, laid on the underlay of a carpet, can bend when anyone treads on it and map, in real-time, their walking patterns.

Tiny electronics at the edges act as sensors and relay signals to a computer. These signals can then be analysed to show the image of the footprint and identify gradual changes in walking behaviour or a sudden incident such as a fall or trip. They can also show a steady deterioration or change in walking habits, possibly predicting a dramatic episode such as a fall.

Tigers don't have a reputation for being accommodating, but a new study indicates that the feared and revered carnivores in and around a world-renowned park in Nepal are taking the night shift to better coexist with their human neighbors.

The revelation that tigers and people are sharing exactly the same space – such as the same roads and trails – of Chitwan National Park flies in the face of long-held convictions in conservation circles. It also underscores how successful conservation efforts need sciences that takes into account both nature and humans.

UCLA researchers have discovered a type of cell that is the "missing link" between bone marrow stem cells and all the cells of the human immune system, a finding that will lead to a greater understanding of how a healthy immune system is produced and how disease can lead to poor immune function.

The studies were done using human bone marrow, which contains all the stem cells that produce blood during postnatal life.

Communities attempting to improve their local food system are increasingly creating food policy councils as an important tool in that effort, but little research has been done into how those councils are functioning.

A team of Johns Hopkins researchers recently conducted a nationwide survey of food policy councils to try to fill some of this research gap. Their results were published online August 24 by the Journal of Agriculture, Food Systems and Community Development.

Hot Towers are towering clouds that emit a tremendous amount of latent heat (thus, called "hot"). NASA research indicates that whenever a hot tower is spotted, a tropical cyclone will likely intensify. Less than 14 hours after the TRMM satellite captured an image of Ileana's rainfall and cloud heights, Ileana strengthened into a hurricane on Aug. 29.

Tropical Storm Tembin made landfall in the in southwestern South Korea and NASA's Aqua satellite captured the extent of the storm's elongated cloud cover, revealing the effect of wind shear on the storm.

Tembin moved through the Myeongnyang Strait and made landfall on Aug. 30, 2012 at 0000 UTC (Aug. 29 at 8 p.m. EDT) in the southwestern tip of South Korea.

Tropical Storm Kirk intensified into a hurricane today, Aug. 30, while another tropical depression was born. Satellite imagery revealed Hurricane Kirk and newborn Tropical Depression 12 romping through the central Atlantic Ocean today, while Tropical Storm Isaac continues to drench the U.S. Gulf coast and Mississippi Valley. Kirk became the Atlantic Ocean season's fifth hurricane today, Aug. 30.

FINDINGS:The Affordable Care Act will fund more community health centers, making primary care more accessible to the underserved. But this may not necessarily lead to better access to subspecialty care.

In a new study, researchers from the David Geffen School of Medicine and Robert Wood Johnson Foundation Clinical Scholars program at UCLA and colleagues investigated the ways in which community health centers access subspecialty care. They identified six major models and determined which of those six offered the best access:
