It's summertime, and the fields of Yolo County, Calif., are filled with rows of sunflowers, dutifully facing the rising sun.
At the nearby University of California, Davis, plant biologists have now discovered how sunflowers use their internal circadian "clocks," acting on growth hormones, to follow the sun during the day as they grow.

In adults with a house dust mite allergy, a cascade of inflammatory signals on the surface of the airways leads to airway remodeling. This process cannot be influenced by standard cortisone therapy. Researchers at Helmholtz Zentrum München and the Technical University of Munich have reported these findings in the latest issue of the Journal of Allergy and Clinical Immunology.

When NASA's Aqua satellite passed over the tropical low pressure area known as System 99L it was located over Hispaniola. The AIRS instrument aboard Aqua analyzed the low pressure area in infrared light.
The Atmospheric Infrared Sounder or AIRS instrument aboard Aqua provided temperature data on System 99L on Aug. 25 at 1:47 p.m. EDT (1747 UTC) . AIRS infrared data showed that the depression had some powerful thunderstorms with high cold cloud tops (as cold as -63F/-53C). NASA research has shown that storms with cloud top temperatures that cold can generate heavy rainfall.

Depending on the intensity track of Typhoon Lionrock, it could pass over Japan with the strength of a lion or or the weakness of a lamb. The intensity track is not clear as yet and some forecasters have it remaining a stronger storm while others have it downgrading significantly in intensity. Lionrock is still a distance away from Japan, currently 307 miles southeast of Kadena AB, Okinawa, Japan, and is moving east northeast at 9 knots per hour. Maximum sustained winds are 105 knots gusting to 130 knots. Further movement will definitely lock in the forecast in the next 24 hours.

CHAMPAIGN, Ill. -- When an important bridge collapsed on Interstate 5 near Mount Vernon, Washington, in 2013, questions were raised about how such a catastrophic failure could occur. A new analysis by a team of civil engineering faculty at the University of Illinois at Urbana-Champaign outlines the many factors that led to the collapse, as well as steps that transportation departments can take to prevent such accidents on other bridges of similar design.

COLUMBIA, Mo. - Each year, millions of people--especially those 65 and older--fall. Such falls can be serious, leading to broken bones, head injuries, hospitalizations or even death. Now, researchers from the Sinclair School of Nursing and the College of Engineering at the University of Missouri found that sensors that measure in-home gait speed and stride length can predict likely falls. This technology can assist health providers to detect changes and intervene before a fall occurs within a three-week period.

Rome, Italy - 27 Aug 2016: A school intervention costing less than 20 cents per child has stopped unhealthy weight gain. The randomised study is presented at ESC Congress 2016 today by Ms Daniela Schneid Schuh, a nutritionist at the Institute of Cardiology of Rio Grande do Sul in Porto Alegre, Brazil.1
"Obesity has reached a plateau in developed countries but continues to rise in many developing countries, such as Brazil," said Ms Schneid Schuh. "Thus, it is necessary to develop low-cost methods to prevent people become overweight, starting in childhood."

The Global Precipitation Measurement mission or GPM core satellite analyzed Tropical Storm Lester after it became the 12th named storm of the 2016 eastern Pacific Ocean on Aug. 25.
GPM, a joint mission between NASA and the Japan Aerospace Exploration Agency, analyzed Lester's rainfall rates and cloud heights.
Lester was far away from the Mexican coast and headed toward the west-northwest. Low vertical wind shear and warm sea surface temperatures are expected to assist in Lester's intensification to hurricane status today, Aug. 26.

- Similar programmes reportedly used in schools in 89 countries, including the USA
- Authors of the randomised trial warn that the intervention is likely to be an ineffective use of public funds
