NIST engineers discover fundamental flaw in transistor noise theory

Chip manufacturers beware: There's a newfound flaw in our understanding of transistor noise, a phenomenon affecting the electronic on-off switch that makes computer circuits possible. According to the engineers at the National Institute of Standards and Technology (NIST) who discovered the problem, it will soon stand in the way of creating more efficient, lower-powered devices like cell phones and pacemakers unless we solve it.

NIST defining the expanding world of cloud computing

A working definition for cloud computing—a new computer technique with potential for achieving significant cost savings and information technology agility—has been released by a team of computer security experts at the National Institute of Standards and Technology (NIST). Since the federal government is considering cloud computing as a component of its new technology infrastructure, it is NIST's role to evaluate it and then promote its effective and secure use within government and industry by providing technical guidance and developing standards.

Blood tests and better communication skills could cut over-prescribing of antibiotics

Improving communications skills and the use of a simple blood test could help cut the growing number of inappropriate prescriptions of antibiotics, a joint Cardiff University trial has discovered.

Telemedicine may improve care for school children with diabetes

Cincinnati, OH, May 21, 2009 -- Type 1 diabetes is the most common chronic childhood disease. The management of this serious medical condition includes regular fingerstick glucose measurements, multiple daily injections of insulin, and frequent insulin dose adjustments. Because children spend a great deal of their time in school, school nurses often supervise medical decisions and diabetes care. Some researchers believe that the use of telecommunication technology may make diabetes care easier for some children.

Physicians can lead health care reform through payment and delivery system reforms

New York, NY, May 20, 2009—Physicians can and should play a leading role in achieving health care reform by working towards comprehensive reform of the way health care is paid for and delivered, helping achieve a guaranteed 1.5 percent annual savings in health care costs that would pay for covering all Americans, according to a New England Journal of Medicine Perspective piece published online today.

SAVI breast cancer applicator 'ideal' for breast cancer conservation therapy

Breast cancer radiation with the SAVI applicator provides outstanding cosmetic and other clinical outcomes, according to two new studies, and is an “ideal solution” for breast conservation therapy patients with small breasts, small tumor beds and minimal distance between the lumpectomy cavity and skin surface.

The studies, which were conducted at Moores Cancer Center at University of California, San Diego, will be presented from the podium at the American Brachytherapy Society’s annual meeting, May 31-June 2, 2009, in Toronto.

Robotic therapy may help neuro-development of kids with cerebral palsy

CAMBRIDGE, Mass.--Over the past few years, MIT engineers have successfully tested robotic devices to help stroke patients learn to control their arms and legs. Now, they're building on that work to help children with cerebral palsy.

"Robotic therapy can potentially help reduce impairment and facilitate neuro-development of youngsters with cerebral palsy," says Hermano Igo Krebs, principal research scientist in mechanical engineering and one of the project's leaders.

MIT replaces chrome coatings with safer metal alloys

CAMBRIDGE, Mass.--Ever since the 1940s, chrome has been used to add a protective coating and shiny luster to a wide range of metal products, from bathroom fixtures to car bumpers.

Chrome adds beauty and durability, but those features come at a heavy cost. Though it's cheap to produce and harmless to consumers, the industrial process to create it is dangerous for workers and pollutes the environment.

New 'broadband' cloaking technology simple to manufacture

WEST LAFAYETTE, Ind. - Researchers have created a new type of invisibility cloak that is simpler than previous designs and works for all colors of the visible spectrum, making it possible to cloak larger objects than before and possibly leading to practical applications in "transformation optics."

Seeing invisible resin

When manufacturing chipboards, it is important to correctly distribute the resin on the wood shavings. Researchers are now developing a measuring technique that makes it possible to monitor the application of the resin during production.

Queen's scientists discover eco-friendly wood dissolution

Scientists at Queen's University Belfast have discovered a new eco-friendly way of dissolving wood using ionic liquids that may help its transformation into popular products such as bio fuels, textiles, clothes and paper.

Dr Héctor Rodríguez and Professor Robin Rogers from the University's School of Chemistry and Chemical Engineering worked along with The University of Alabama, Tuscaloosa, AL, to come up with a more cost and energy efficient way of processing wood.

Quality measures improve outcomes more than hospital volume alone

A new study by researchers at the University of California, San Francisco and Baystate Medical Center at Tufts University in Massachusetts concludes that patients facing coronary artery bypass surgery should, as a first priority, select a medical facility that has the highest adherence to quality standards.

Lifestyle program for patients with COPD is health and cost effective

ATS 2009, SAN DIEGO—Patients with moderate COPD were randomized to receive "usual care" or to undergo an interdisciplinary, community-based program (INTERCOM) that offered an intensive lifestyle moderation phase of four months, during which patients were instructed in detail to perform two 15-minute intervals of pleasurable walking or cycling, and offered instruction in other lifestyle changes such as nutrition and smoking cessation.

Dying at home: A trend that could make hospitals more efficient

Hospitals across Canada are seeking ways to free up beds. University of Alberta researcher Donna Wilson has a suggestion: people should be encouraged to die at home rather than in hospital.

She looked at statistics dating back to 1950 and has found that there's been a dramatic change in the location of death of Canadians. Up until 1994, about 80 per cent of people dying each year were passing on in hospital. Now that number is down to 61 per cent, and Wilson is hoping the trend continues.
