Spills of fuel with more ethanol could endanger people, buildings
Date: Dec-18-2013Blending more ethanol into fuel to cut air pollution from vehicles carries a hidden risk that toxic or even explosive gases may find their way into buildings, according to researchers at Rice University.Those problems would likely occur in buildings with cracked foundations that happen to be in the vicinity of fuel spills. Vapors that rise from contaminated groundwater can be sucked inside, according to Rice environmental engineer Pedro Alvarez. Once there, trapped pools of methane could ignite and toxic hydrocarbons could cause health woes, he said.

Intermittent vision of the action can improve brain's visual perception, improve hockey players' performance
Date: Dec-18-2013Professional hockey players who trained with special eyewear that only allowed them to see action intermittently showed significant improvement in practice drills, according to a Duke University study with the NHL's Carolina Hurricanes.The eyewear features lenses that switch between transparent and opaque, producing stroboscopic visual conditions, much like a strobe light in your favorite dance club.Earlier research using the stroboscopic eyewear during training showed improved vision, visual attention, and ability to anticipate the timing of moving items.
Improved outcomes for women with triple-negative breast cancer with new pre-surgery combination therapy
Date: Dec-18-2013The I-SPY 2 trial, an innovative, multidrug, phase II breast cancer trial, has yielded positive results with the first drug to complete testing in the trial. Adding the chemotherapy carboplatin and the molecularly targeted drug veliparib to standard presurgery chemotherapy improved outcomes for women with triple-negative breast cancer, according to results from the I-SPY 2 trial presented at the 2013 San Antonio Breast Cancer Symposium.
Cholesterol-tracking smartphone users take lifesaving selfies
Date: Dec-18-2013With a new smartphone device, you can now take an accurate iPhone camera selfie that could save your life - it reads your cholesterol level in about a minute.Forget those clumsy, complicated, home cholesterol-testing devices. Cornell engineers have created the Smartphone Cholesterol Application for Rapid Diagnostics, or "smartCARD," which employs your smartphone's camera to read your cholesterol level.
Protection against what can be a fatal rickettsial infection
Date: Dec-18-2013Researchers at the University of Texas Medical Branch at Galveston have discovered a way to block a disease pathway that could be a breakthrough in defeating some of the world's most devastating human infections.Rickettsioses are a group of insect-borne diseases caused by bacteria. One type, typhus fever, has been cited as a high-level threat by the National Institutes of Health because the bacteria can spread and multiply very easily, and the untreated infection can lead to death.What researchers at UTMB have found is a way to protect against what can be a fatal rickettsial infection.
Body mass index 'in and of itself' increases risk of developing chronic kidney disease
Date: Dec-18-2013A new UCSF-led study of nearly 3,000 individuals links obesity to the development of kidney disease. The work also shows that, when properly measured, declines in kidney function are detectable long before the emergence of other obesity-related diseases such as diabetes and high blood pressure.Healthy kidneys are vital to the proper functioning of the heart and brain, as well as the skeletal and immune systems, and the research adds additional urgency to the call for doctors to intervene early in life with obese patients, the researchers said.
High-speed photography provides first direct evidence of how microbubbles dissolve killer blood clots
Date: Dec-18-2013Ultrasound-stimulated microbubbles have been showing promise in recent years as a non-invasive way to break up dangerous blood clots. But though many researchers have studied the effectiveness of this technique, not much was understood about why it works. Now a team of researchers in Toronto has collected the first direct evidence showing how these wiggling microbubbles cause a blood clot's demise. The team's findings are featured in the AIP Publishing journal Applied Physics Letters.
Evidence of Savings in Accountable Care Organizations and Cancer Care
Date: Dec-18-2013Approximately 10 percent of Medicare spending is for cancer care, and Medicare spending is nearly four times higher for beneficiaries with cancer than in those without the disease. Little is known about how to curb spending growth while maintaining or improving quality of care for these high-risk, high-cost patients.Researchers from The Dartmouth Institute for Health Policy & Clinical Practice report that savings may be found in accountable care organizations (ACO) through reductions in hospitalizations.
