Cardiovascular disease causing increasing inequity between rich and poor
A new paper released today by The George Institute for International Health is warning a cardiovascular disease based epidemic is gaining pace among many low- and middle-income countries (LMIC), exemplified at its worst in the world's largest populated countries - China and India.

Can you hear me now? How the inner ear's sensors are made
A UCLA study shows for the first time how microscopic crystals form sound and gravity sensors inside the inner ear. Located at the ends of cilia - tiny cellular hairs in the ear that move and transmit signals - these crystals play an important role in detecting sound, maintaining balance and regulating movement.

Fruit fly research may lead to better understanding of human heart disease
Researchers at the Burnham Institute for Medical Research (Burnham) have shown in both fruit flies and humans that genes involved in embryonic heart development are also integral to adult heart function. The study, led by Rolf Bodmer, Ph.D., was published in Proceedings of National Academy of Sciences.

Self-powered devices possible, says Texas A&M researcher
Imagine a self-powering cell phone that never needs to be charged because it converts sound waves produced by the user into the energy it needs to keep running. It's not as far-fetched as it may seem thanks to the recent work of Tahir Cagin, a professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University.

Brown Chemist Finds Gene That Enables Gray Mold to Kill Plant Cells
Gray mold is a gardener's nightmare. The fungus, also known by its scientific name Botrytis cinerea, is a scourge to more than 200 agricultural and ornamental plant species, including staples such as tomatoes, strawberries, snap and lima beans, cabbage, lettuce and endive, peas, peppers, and potatoes.

Foretelling a major meltdown
By discovering the meaning of a rare mineral that can be used to track ancient climates, Binghamton University geologist Tim Lowenstein is helping climatologists and others better understand what we're probably in for over the next century or two as global warming begins to crank up the heat - and, ultimately, to change life as we know it.

Ice beetles impacted by climate change
In the summer of 1968, Dave Kavanaugh set off on a hike that would change the course of his life. As a second-year medical student at the University of Colorado, he had joined a climbing club with a few members of the biophysics department, and the group had set their sights on Gray's Peak-the ninth highest mountain in Colorado.

Delays in Radiation Therapy Lead to Increased Breast Cancer Recurrence
A new analysis of the National Cancer Institute's cancer registry has found that as many as one in five older women experience delayed or incomplete radiation treatment following breast-conserving surgery, and that this suboptimal care can lead to worse outcomes.

Stanford blood scanner detects even faint indicators of cancer
A team led by Stanford researchers has developed a prototype blood scanner that can find cancer markers in the bloodstream in early stages of the disease, potentially allowing for earlier treatment and dramatically improved chances of survival.

Women with Mitral Valve Prolapse are Treated Less Aggressively Than Men and May be at High Risk
Disturbing evidence of higher mortality and lower surgery rates in women versus men with mitral valve prolapse and severe leakage may be related to the complexity of evaluating the condition's severity in women, according to findings of a Mayo Clinic study published this month in the Annals of Internal Medicine.

Rutgers-Camden Scholar Identifies Genetic Patterning in Fruit Fly Development
No matter the species, from flies to humans, we all start the same: a single-cell fertilized egg that embarks on an incredible journey. The specifics of this journey are being uncovered at Rutgers University-Camden, where a biologist is researching how from one cell a jumble of many are able to organize and communicate, allowing life to spring forth.

New mammography technology effective in detecting breast cancer
A study has found that positron emission mammography (PEM), a new technique for imaging the breast, is not affected by either breast density or a woman's hormonal status, two factors that limit the effectiveness of standard mammography and MRI at detecting cancer.

New approach eliminates software deadlocks using discrete control theory
Software deadlocks are the Catch-22s of the computer world. These common bugs can freeze the machine when different parts of a program end up in an endless cycle of waiting for one another as they access shared data.

Patient photos spur radiologist empathy and eye for detail
Including a patient's photo with imaging exam results may enable a more meticulous reading from the radiologist interpreting the images, as well as a more personal and empathetic approach, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
