New research from the University of Adelaide shows that the sperm of obese fathers could increase the risk of both their children and their grandchildren to inherit obesity.
Swarms of small earthquakes can precede a volcanic eruption, sometimes resulting in "harmonic tremor" resembling sound from some musical instruments. A new analysis shows tremor during a 2009 sequence at Alaska's Redoubt Volcano glided to substantially higher frequencies, then stopped abruptly just before six of the eruptions.
Using a technique to measure the energy required for electrons to pair up and how that energy varies with direction, scientists have identified the factors needed for magnetically mediated superconductivity—as well as those that aren’t.

The findings suggest that these naturally produced mutations are just as powerful as known cancer-causing agents in producing tumors.
A study on HIV-positive women who were sexually abused as children has found that the more severe their past trauma, the greater their improvement in an intervention program designed to ease their psychological suffering.
New research finds that almost two-thirds of female survivors of childhood cancer who tried unsuccessfully for at least a year to conceive eventually got pregnant.
A Johns Hopkins study finds that healthy people who carry a genetic mutation for arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) are at much higher risk of developing the symptoms of the life-threatening heart disease if they participate in endurance sports and frequent exercise. The study also suggests that those carriers who significantly cut back on their exercise regimen may reduce their risk or delay the onset of symptoms.
Older African-American and Hispanic men who have survived cancer are less likely than their white counterparts to see a specialist or receive basic preventive care, such as vaccinations, according to new research from Wake Forest Baptist Medical Center.

A researcher finds correlation between financial arguments, decreased relationship satisfaction.
At the height of the AIDS epidemic in the 1980s men who were married were significantly less likely to die of HIV/AIDS than their single counterparts. For women, marital status had little impact on who was more likely to die of the disease. But race proved to be a significant risk factor.
Scientists have created a virtual model of the brain that daydreams like humans do. They hope the model will help them understand why certain portions of the brain work together when a person is mentally idle.
• Among kidney disease patients receiving pre-dialysis care in a universal healthcare system, black patients experienced a faster progression to kidney failure than whites. • The faster decline in kidney function among black compared with white patients was predominantly present in patients with diabetes and in patients with more advanced kidney dysfunction.
• A novel drug called Bendavia can help prevent acute kidney injury in animal models and is currently being studied in clinical trials for kidney disease. • Bendavia acts by protecting a unique compound called cardiolipin, which is only found in mitochondria and is essential for keeping cells alive and functioning.
When we think of our prehistoric ancestors, we don’t usually imagine them lining graves with flowers – yet Weizmann scientists have now identified the oldest such grave. Using the Institute’s new accelerator mass spectrometer, the team will not only uncover new information about prehistoric life, but also overturn some long-held theories.

National quality assessment programs usually measure and reward practices based on improving clinical processes such as re-hospitalization or infection rates. While this type of information is important and useful to clinicians, it doesn’t always take into account what is most important to the patient and families of the patient receiving care, such as the management of long-term symptoms or ability to conduct daily activities.
Researchers at Albert Einstein College of Medicine of Yeshiva University have found that nerves play a critical role in both the development and spread of prostate tumors. Their findings, using both a mouse model and human prostate tissue, may lead to new ways to predict the aggressiveness of prostate cancer and to novel therapies for preventing and treating the disease. The study published online today in the July 12 edition of Science.

A Vanderbilt research program that trains community pediatricians to diagnose autism within their individual practices may lead to more effective treatment of the disorder that now affects an estimated one in 88 children.
Mexican American children are experiencing substantial burdens of obesity, pre-diabetes, and other health problems which historically would have been expected to develop much later in life. The findings of a new study by Texas Biomed scientists in San Antonio argue for early screening and intervention to delay or avoid chronic health problems as these children age.
Astronomers using NASA's Hubble Space Telescope have deduced the actual visible-light color of a planet orbiting another star 63 light-years away. If seen directly the planet, known as HD 189733b, would look like a "deep blue dot," reminiscent of Earth's color as seen from space.
In a study recently published online in The Journal of the American Medical Association Dermatology, Marianne Berwick, PhD, and her international team of melanoma researchers confirmed that the chances of dying from skin cancer depend strongly upon how thick the primary tumor is. But — unexpectedly — the team also found that those having more than one primary tumor have better survival odds.
Medical diagnostic and security scanners with higher sensitivity could result from University of Adelaide research into detecting T-rays (terahertz waves).
Deep brain stimulation therapy blocks or modulates electrical signals in the brain to improve symptoms in patients suffering from movement disorders such as Parkinson’s disease, essential tremor and dystonia, but a new study suggests that several factors may cause electrical current to vary over time.
Children who receive a vaccine to prevent blood and ear infections, appear to be reducing the spread of pneumonia to the rest of the population, especially their grandparents and other older adults.

Researchers at the University of Arkansas have identified that water, when chilled to a very low temperature, transforms into a new form of liquid.
Researchers at Joslin Diabetes Center have discovered that when excessive PKC beta is found in the endothelium, the thin layer of cells that line blood vessels, atherosclerosis is exacerbated. Their findings could lead to treatments to reduce the risk of CVD in people with type 1 and type 2 diabetes.
The study used data from the Carolina Breast Cancer Study (CBCS) Phase III, a program of UNC Lineberger Comprehensive Cancer Center. Scientists found that among White women, household size and losing a job due to one's diagnosis were reasons for delay in treatment, while among African-American women, the type of treatment received influenced delay. Both African-American and white women experienced delay if they underwent immediate breast reconstruction following mastectomy. African-American women were more likely than white women to experience delay associated with this procedure (92.5 percent versus 60.6 percent).
