Gates Foundation continues funding of tuberculosis research at Weill Cornell
Weill Cornell Medical College announced today that it was awarded two $100,000 grants from the Bill & Melinda Gates Foundation as part of the next phase of Grand Challenges Explorations, an initiative to encourage bold and unconventional ideas for global health. The grants will provide continued support to promising and innovative global health research projects conducted by Dr. Carl Nathan, titled

New tech to help protect bridges, other infrastructure from scour
New technology allows engineers to assess the scour potential of soils at various depths and on-site for the first time -- which will help evaluate the safety of civil infrastructure before and after storm events. Scour, or erosion of soil around structures due to water flow, is responsible for a wide range of critical infrastructure failures -- from unstable bridges to the levees that gave way in the wake of Hurricane Katrina.

Every person emits 2 tons of CO2 a year through eating
Every person emits the equivalent of approximately two tons of carbon dioxide a year from the time food is produced to when the human body excretes it, representing more than 20 percent of total yearly emissions. That is what a study by the Universidad de Almeria says, confirming for the first time that human excrement contributes to water pollution, primarily with nitrogen and phosphorus.

Internal body clock controls fat metabolism, UCI study shows
UC Irvine researchers have discovered that circadian rhythms -- the internal body clock -- regulate fat metabolism. This helps explain why people burn fat more efficiently at certain times of day and could lead to new pharmaceuticals for obesity, diabetes and energy-related illnesses.

First compelling evidence for a black hole after recent supernova
Black holes, or the remnants of hyper-or supernova explosions, have intrigued scientists since the concept was first introduced in 1967. Astronomers have only ever been able to observe gamma-ray bursts, considered the births of young black holes, at far distance. Researchers have now found compelling evidence for the birth of a black hole in the so-called local Universe -- representing the youngest black hole ever discovered in our cosmic neighborhood.

Existing headgear and mouth guards have limited or no benefit in reducing concussions in rugby players, according to Dr. Michael Cusimano, a neurosurgeon at St. Michael's Hospital.

Were our tetrapod ancestors deaf?
A research group led by Jakob Christensen-Dalsgaard, University of Southern Denmark, have shown that the closest living relatives of the tetrapods, the lungfish, are insensitive to sound pressure, but sensitive to vibrations. The discovery was published online in Biology Letters on Sept. 8.

Parental infertility and cerebral palsy in children born spontaneously or after IVF/ICSI
Doctors have known for some time that children born after some fertility treatments are at increased risk of cerebral palsy. However, it was not known whether this risk was due to the treatment itself, the higher frequency of preterm or multiple births, or a mechanism associated with couples' underlying infertility. Now, new research published in Human Reproduction journal indicates that underlying infertility is NOT the main reason for the increased risk seen in IVF/ICSI children.

Severely injured should go directly to trauma center: Research
Severely injured patients should be transported directly from the scene of an accident to a trauma center, even if it means bypassing a closer hospital, according to new research that shows this results in a nearly 25 percent lower death rate.

BGI researchers sequenced the human methylome at single base-pair resolution
DNA methylation plays an important role in many processes such as animal development, X-chromosome inactivation, and carcinogenesis. Understanding the mechanisms and functions of DNA methylation and how it varies from tissue to tissue and between individuals will have profound implications for human health and disease.

When considering both harm to self and harm to others, alcohol is the most harmful drug, followed by crack and heroin
In an article published online first and in an upcoming Lancet, drug experts present a new scale of drug harm that assesses both harm to the individual and harm to others. Their analysis shows that when both factors are combined, alcohol is the most harmful drug, followed by heroin and crack. The paper is written by Professor David Nutt.

Caffeinated alcoholic beverages -- a growing public health problem
In the wake of multiple state bans on caffeinated alcoholic beverages (CABs) and an FDA warning to four companies to remove their products from the marketplace, an article published online today in the American Journal of Preventive Medicine delineates the scope of the public health problem and suggests areas of research that might help address it.

People who have an allotment, especially those aged over 60, tend to be significantly healthier than those who do not. Researchers writing in BioMed Central's open access journal Environmental Health have shown that the small gardens were associated with increased levels of physical activity at all ages, and improved health and well-being in more elderly people.

Nearly all depressed adolescents recover with treatment, but half relapse
A study of adolescents who had a major depressive disorder found that nearly all recovered from their episode after treatment. But within five years, nearly half of them had relapsed, and females were at much higher risk of another major episode, researchers at Duke University Medical Center found.

Researchers learn that genetics determine winter vitamin D status
The authors concluded that during the winter vitamin D status is governed mainly by genetic factors. Conversely, non-genetic factors are most important during the summer. Future studies designed to better understand what these factors are will be especially useful as public health experts continue to explore ways to increase vitamin D status in different populations living under varying environmental and dietary situations.

Evolutionary divergence of humans from chimpanzees likely occurred some 8 million years ago rather than the 5 million year estimate widely accepted by scientists, a new statistical model suggests.

A 'brand' new world: Attachment runs thicker than money
Can you forge an emotional bond with a brand so strong that, if forced to buy a competitor's product, you suffer separation anxiety? According to a new study from the USC Marshall School of Business, the answer is yes. In fact, that bond can be strong enough that consumers are willing to sacrifice time, money, energy and reputation to maintain their attachment to that brand.
