Scientists in California are reporting development of a new generation of the microcapsules used in carbon-free copy paper, in which capsules burst and release ink with pressure from a pen. The new microcapsules burst when exposed to light, releasing their contents in ways that could have wide-ranging commercial uses from home and personal care to medicine. Their study appears in the Journal of the American Chemical Society, a weekly publication.

Where does it come from? Scientists in Arizona are reporting a surprising answer to that question, which has puzzled and perplexed generations of men and women confronted with layers of dust on furniture and floors. Most of indoor dust comes from outdoors. Their report is scheduled for the Nov. 1 issue of ACS' Environmental Science & Technology, a semi-monthly journal.
ESA's SMOS (Soil Moisture and Ocean Salinity) and Proba-2 (PRoject for OnBoard Autonomy) satellites are scheduled for launch on Monday 2 November at 02:50 CET on a Russian Rockot launcher from the Plesetsk cosmodrome in northern Russia.
Residents can serve a vital role in educating Congress, the medical community, and the general public regarding the efficacy of cutting-edge technologies like CT colonography (CTC) as well as the importance of radiologists' training and education and the role that radiologists serve in the provision of quality health care, according to an article published in the November issue of the Journal of the American College of Radiology (JACR).
MADISON, WI, OCTOBER 27, 2009 -- Phosphorus is an essential element in production agriculture, however fertilizer runoff and wastewater discharge have led to massive eutrophication problems in water bodies worldwide.
MADISON, WI, OCTOBER 27, 2009 -- Worldwide leaders in agricultural research, science policy, and soil science will address emerging developments in plant and soil sciences as daily plenary lectures during the 2009 Annual Meetings of the American Society of Agronomy (ASA), Crop Science Society of America (CSSA), and Soil Science Society of America (SSSA), Nov. 1-5 in Pittsburgh, PA.The meeting will be held at the David L. Lawrence Convention Center in Pittsburgh, PA. The four daily plenary lecturers are:
The United Kingdom's deepest diving Autonomous Underwater Vehicle (AUV), Autosub6000, has been put through its paces during an extremely successful engineering trials cruise on the RRS Discovery, 27 September to 17 October 2009.
Autosub6000 was working in regions of the Iberian Abyssal Plain in the North Atlantic deeper than 5600 metres and also around the steep and rugged terrain of the Casablanca Seamount, between Madeira and Morocco. The vehicle was designed and constructed by engineers at the Underwater Systems Laboratory in the National Oceanography Centre, Southampton.
CSIRO researchers have identified wheat and barley lines resistant to Crown Rot – a disease that costs Australian wheat and barley farmers $79 million in lost yield every year.
Crown Rot, which is a chronic problem throughout the Australian wheat belt, is caused by the fungus Fusarium.
Dr Chunji Liu and his CSIRO Plant Industry team in Brisbane are using sophisticated screening methods to scan over 2400 wheat lines and 1000 barley lines from around the world to find the ones resistant the fungal disease.
ROCHESTER, Minn. -- The design of a consultation room can improve the quality of a visit to the physician's office. A collaborative research study developed by Nurture by Steelcase and Mayo Clinic, was conducted to understand the extent to which a consultation room designed to support present-day clinical encounters could affect the consultation between patients and clinicians. The results of this randomized trial, the first of its kind, will appear in the October issue of Health Environments Research and Design Journal (HERD).
ATLANTA—October 28, 2009—A new report from an American Cancer Society (ACS) scientific advisory subcommittee on cancer and the environment says exposure to carcinogens should be minimized or eliminated whenever feasible, and calls for new strategies to more effectively and efficiently screen the large number of chemicals to which the public is exposed.
Although nearly 80 percent of the U.S. population lives within 2 hours by ground or helicopter transport to a verified burn center, there is substantial state and regional variation in geographic access to these centers, according to a study in the October 28 issue of JAMA.
Compared to the general population, patients starting dialysis have an increased risk of death that is not attributable to a higher rate of death from cardiovascular causes, as previously thought, according to a study in the October 28 issue of JAMA.
After decades of focusing on the management of respiratory failure, circulatory shock and severe infections that lead to extended stays in hospital intensive care units, critical care researchers are increasingly turning attention to what they believe is a treatable complication developed by many who spend days or weeks confined to an ICU bed: debilitating muscle weakness that can linger long after hospital discharge.
A multidisciplinary team of UC researchers is the first to find an innovative and novel way to control an electron's spin orientation using purely electrical means.
Their findings were recently published in the prestigious, high-profile journal "Nature Nanotechnology," in an article titled "All-Electric Quantum Point Contact Spin-Polarizer."
Researcher Dr. David H. Hughes of the Air Force Research Laboratory in Rome, N.Y. is leading a team investigating long-distance, mobile optical links imperative for secure quantum communications capabilities in theater.
Hughes and his Air Force Office of Scientific Research-funded team have conducted high data-rate experiments using an optical laser link, a tool which exploits the quantum noise of light for higher security. The system uses adaptive optics for transmission of high data-rate video and audio signals over long distances.
