NASA sees former Tropical Storm Carlos still a soaker in the Northern Territory

Now a remnant low pressure area, former Tropical Storm Carlos continues to move southwest inland over Australia's Northern Territory and dump heavy amounts of rainfall. NASA's Aqua satellite saw some of the high thunderstorms within Carlos over land and extending north into the Timor Sea.

NASA sees heavy rains in Tropical Storm Bingiza, possibly headed for second landfall

NASA satellite data indicates that Bingiza is still maintaining tropical storm intensity and carrying heavy rainfall over the Mozambique Channel as it prepares for its second landfall in Madagascar.

Inexpensive rinsing effective at reducing post-op infection following joint replacement surgery

CHICAGO – A rinsing technique with betadine that costs just a little over one dollar per patient may significantly reduce the infection rate following total knee and hip joint replacement surgery according to a study by researchers at Rush University Medical Center.

The study, presented at the American Association of Orthopedic Surgeons 2011 Annual Meeting, found that a three minute diluted betadine lavage combined with painting of the skin with a 10% betadine solution prior to surgical closure nearly eliminated early deep post-operative infection.

Compact high-temperature superconducting cables demonstrated at NIST

A researcher at the National Institute of Standards and Technology (NIST) has invented a method of making high-temperature superconducting (HTS) cables that are thinner and more flexible than demonstration HTS cables now installed in the electric power grid while carrying the same or more current. The compact cables could be used in the electric grid as well as scientific and medical equipment and may enable HTS power transmission for military applications.

Scientists build world's first anti-laser

New Haven, Conn.—More than 50 years after the invention of the laser, scientists at Yale University have built the world's first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. The discovery could pave the way for a number of novel technologies with applications in everything from optical computing to radiology.

Improving microscopy by following the astronomers' guide star

A corrective strategy used by astronomers to sharpen images of celestial bodies can now help scientists see with more depth and clarity into the living brain of a mouse. Eric Betzig, a group leader at the Howard Hughes Medical Institute's Janelia Farm Research Campus, will present his team's latest work using adaptive optics for biology at the annual meeting of the American Association for the Advancement of Science in Washington, D.C. during a press conference on Thursday, Feb., 17, and a panel discussion on Friday, Feb. 18.

The green machine: Algae clean wastewater, convert to biodiesel

Let algae do the dirty work.

Researchers at Rochester Institute of Technology are developing biodiesel from microalgae grown in wastewater. The project is doubly "green" because algae consume nitrates and phosphates and reduce bacteria and toxins in the water. The end result: clean wastewater and stock for a promising biofuel.

Checklist cuts lethal ventilator-associated lung infections

Cases of ventilator-associated pneumonia — the most lethal and among the most common of all hospital-associated infections — dropped by more than 70 percent in Michigan hospitals where medical staff used a simple checklist designed by Johns Hopkins researchers. Such pneumonias kill an estimated 36,000 Americans each year.

Everything you wanted to know about microbes and oil spills but were afraid to ask

Is it true that microbes cleaned up the oil spill in the Gulf of Mexico? Can bacteria really "eat" oil, and if so, how? To help clear up the confusion the American Academy of Microbiology has brought together the nation's leading experts to consider and answer some of the most frequently asked questions regarding microbes and oil spills.

Improved behavioral health needed to respond to rising number of suicides among US Armed Forces

U.S. military officials should improve efforts to identify those at-risk and improve both the quality and access to behavioral health treatment in response to a sharp rise in suicide among members of nation's armed forces, according to a new RAND Corporation study.

Needed changes include making service members aware of the advantages of using behavioral health care, ensuring that providers and chaplains are delivering high quality care, and assuring that service members can receive confidential help for their problems, according to the report.

Turning forests into fuel: New report outlines promise and limits of biomass energy in the Northeast

(Millbrook, N.Y. – Feb 17, 2011) Forest biomass could replace as much as one quarter of the liquid fossil fuel now being used for industrial and commercial heating in the Northeastern United States. That's according to a new report released today by the Cary Institute of Ecosystem Studies.

Vitamin E may increase or decrease the risk of pneumonia depending on smoking and exercise

Depending on the level of smoking and leisure time exercise, vitamin E supplementation may decrease or increase, or may have no effect, on the risk of pneumonia, according to a study published in Clinical Epidemiology.

In laboratory studies, vitamin E has influenced the immune system. In several animal studies vitamin E protected against viral and bacterial infections. However, the importance of vitamin E on human infections is not known.

Higher levels of social activity decrease the risk of developing disability in old age

CHICAGO—Afraid of becoming disabled in old age, not being able to dress yourself or walk up and down the stairs? Staying physically active before symptoms set in could help. But so could going out to eat, playing bingo and taking overnight trips.

According to research conducted at Rush University Medical Center, higher levels of social activity are associated with a decreased risk of becoming disabled. The study has just been posted online and will be published in the April issue of the Journal of Gerontology: Medical Sciences.

Sleeping Trojan horse to aid imaging of diseased cells

A unique strategy developed by researchers at Cardiff University is opening up new possibilities for improving medical imaging.

Medical imaging often requires getting unnatural materials such as metal ions into cells, a process which is a major challenge across a range of biomedical disciplines. One technique currently used is called the 'Trojan Horse' in which the drug or imaging agent is attached to something naturally taken up by cells.

Preterm mothers' milk contains less antioxidants than mothers completing their gestation

A study conducted at the University of Granada and at the University Hospital San Cecilio revealed that preterm mothers' milk contains low concentrations of coenzyme Q10. This is a complex of great medical importance, due both to its antioxidant capacity and to its role as a component of the electron transport chain, among other functions.
