| Newly discovered features of collagen may help shed light on disease processes Posted: 12 Jul 2016 02:34 PM PDT Scientists are reporting new, unexpected details about the fundamental structure of collagen, the most abundant protein in the human body. In lab experiments, they demonstrated that collagen, once viewed as inert, forms structures that regulate how certain enzymes break down and remodel body tissue. The finding of this regulatory system provides a molecular view of the potential role of physical forces at work in heart disease, cancer, arthritis, and other disease-related processes, they say. |
| Research highlights the legal issues of certifying emotional support animals Posted: 12 Jul 2016 02:33 PM PDT Service animals are recognized by the ADA as those whose training helps them serve a specific disability-related function. However, people not necessarily exhibiting a mental or physical disability are eluding the system by asking their mental health professionals to certify 'emotional support animals'. Researchers are exploring the effects these requests are having on the mental health profession and recommend that psychologists refrain from issuing certifications to avoid legal risks. |
| Progress towards protection from highly lethal Ebola, Marburg viruses Posted: 12 Jul 2016 02:33 PM PDT Ebola and Marburg filovirus disease outbreaks have typically occurred as isolated events, confined to central Africa. However, the recent Ebola epidemic spread to several African countries, and caused 11,000 deaths. That epidemic underscored the need to develop vaccines and therapeutics that could be used to fight future disease outbreaks. Now new research suggests that antibodies to filoviruses from individuals who have survived these diseases may offer protection -- not only against the particular filovirus that infected an individual, but against other filoviruses, as well. |

New research explains why Posted: 12 Jul 2016 02:30 PM PDT Dieters tend to adopt the wrong strategies, often planning to ditch their favorite foods and replace them with less-desirable options, according to new research. Conversely, successful dieters focus on adding healthy foods -- foods that they actually like. |
| Black hole makes material wobble around it Posted: 12 Jul 2016 12:35 PM PDT The European Space Agency's orbiting X-ray observatory, XMM-Newton, has proved the existence of a "gravitational vortex" around a black hole. The discovery, aided by NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) mission, solves a mystery that has eluded astronomers for more than 30 years, and will allow them to map the behavior of matter very close to black holes. It could also open the door to future investigations of Albert Einstein's general relativity. |
| The moral tipping point: Why it's hard to shake a bad impression Posted: 12 Jul 2016 11:27 AM PDT People require more evidence to perceive improvement in someone's moral character than to perceive a decline, research shows. In other words, it is easier to become a sinner than a saint. |
| New method to model protein interactions may help accelerate drug development Posted: 12 Jul 2016 11:27 AM PDT Protein-protein interactions (PPIs) are the basis of cellular functions, and when these processes are compromised diseases such as cancer emerge.

To succeed in this endeavor, scientists have responded with complex, creative and elegant approaches unparalleled in other vaccine research pursuits, according to a new article. |
| Male circumcision, HIV treatment can significantly reduce new infections in African men Posted: 12 Jul 2016 08:53 AM PDT Increasing the number of men who undergo circumcision and increasing the rates at which women with HIV are given antiretroviral therapy were associated with significant declines in the number of new male HIV infections in rural Ugandan communities, new research has shown. |
| Study shows a rising, but uneven, tide of in-home care for disabled seniors Posted: 12 Jul 2016 08:53 AM PDT More seniors are getting help from family, friends and hired helpers to keep them in their homes, despite disabilities that keep them from total independence, a new study finds. Half of disabled seniors in a long-term study got in-home help in 2012, up 20 percent from the late 1990s. But that increase isn't happening evenly across all groups -- and has implications for the careers and health of caregivers. |
