Oklahoma scientists say earthquakes linked to oil and gas work Oklahoma geologists have documented strong links between increased seismic activity in the state and the injection into the ground of wastewater from oil and gas production, a state agency said on Tuesday. Currently, Oklahoma is recording 2-1/2 earthquakes daily of a magnitude 3 or greater, a seismicity rate 600 times greater than observed before 2008, the report by the Oklahoma Geological Survey (OGS) said. It is "very likely that the majority of the earthquakes" are triggered by wastewater injection activities tied to the oil and gas industry, the OGS said. Prior to 2008, Oklahoma averaged less than two a year.

Though perplexing, the phenomenon — known as the "bystander effect" — is common, experts said. "There's this kind of paradoxical relationship, where the more people [there are who] observe an incident, the less likely any single individual is to help," said Peter Ditto, a professor of psychology and social behavior at the University of California, Irvine.

Researchers analyzed information from nearly 1,700 women living in Los Angeles who had ovarian cancer and about 2,380 women living in the same area who did not have ovarian cancer. The researchers found that each five-year increase in a woman's age at the birth of her first child corresponded to a 16 percent lower risk of ovarian cancer. So, for example, women who gave birth to their first child at age 35 or later had a 46 percent decrease in their risk of ovarian cancer compared with women who gave birth to their first child when they were younger than 20.

The data collected by the smartphones are giving researchers a clearer overall picture of asthma attacks and inhaler use, which, in turn, could allow researchers to map out the areas linked to respiratory disease and even reveal some of the underlying triggers of asthma symptoms. "We're collecting data about daily lives and medications," said Chris Hogg, chief operating officer of Propeller Health, a company in Madison, Wisconsin, that provides both hardware and software for managing asthma. Whenever Propeller's "smart" inhaler is used, the phone's geolocation services log exactly where the patient is when he or she is using it.

The car's British designers say they are pushing the limits of science, with the Bloodhound a catalyst for cutting-edge research in fields such as aerodynamics and sustainable high-tech engineering. At their headquarters near Bristol, the Bloodhound team is busy constructing and assembling the vehicle's 3,500 bespoke components ahead of the car's unveiling in August. Bloodhound SSC (supersonic car) will be driven by Wing Commander Andy Green who set the current record of 763mph (1228kmh) at the wheel of ThrustSSC in 1997.

No matter how hard or how many times Amanda hits the drones' wing, it always recovers and keeps on flapping. Stowers says that even drones equipped with advanced sensors can't avoid the inevitable. The ability to maneuver in tight and cluttered environments could allow drones to play an important role in search and rescue operations, giving first responders the ability to search for survivors remotely.

Is Freezing Your Eggs Worth the Cost? Scientists ran all the numbers — the cost of egg freezing, the odds of having a baby at age 40 without in vitro fertilization and the cost of IVF for women who will need it in order to have a baby — and found that it costs about $15,000 less, on average, for women to freeze their eggs at age 35 and use them at age 40, rather than wait until age 40 and try to become pregnant. The study shows that "if a woman invested in having a genetically related child at age 40, egg banking at least once at age 35 is a cost-effective approach," said Dr. Wendy Vitek, an assistant professor of obstetrics and gynecology at the University of Rochester Medical Center in Rochester, New York.

"They made it really clear this time around, unlike 2009, that the discussion between a woman and a clinician about breast cancer screening should begin at 40," said Dr. Richard Wender, chief cancer control officer at the American Cancer Society. The Department of Health and Human Services provided for mammogram coverage for women age 40 to 49 after the health panel made its recommendation in 2009. The department said on Monday that the guidelines are only in draft form and that nothing has changed regarding access to mammograms or other preventive services. Critics stressed that keeping 50 as the starting age for screening – a change first introduced by the panel six years ago - could threaten insurance coverage for millions of women age 40 to 49. "If this becomes the final guideline, coverage of mammograms would no longer be mandated under the ACA," said Wender.

Depression is one of the most common forms of mental illness, affecting more than 350 million people worldwide. It is ranked by the World Health Organization as the leading cause of disability globally. Treatment usually involves either medication, some form of psychotherapy or a combination of both.

Dutch start-up Nerdalize has teamed up with energy providers Eneco to launch its e-Radiator prototype, which is being tested in five Dutch homes as an alternative heating device. The e-Radiator is a computer server that crunches numbers for a variety of Belgian firms - while the resultant heat will heat the rooms in which they're situated. Nerdalize believes the scheme could be a commercially viable alternative to traditional radiators.

This time, the finding comes from a study of children at high risk of developing autism. The researchers found that there was no link between receiving the MMR vaccine and developing autism, even for the children who had an increased risk of autism because their older siblings had been diagnosed with the condition. The researchers wanted to look at more data on the MMR vaccine and autism risk because "despite the research that shows no link between the MMR vaccine [and autism], parents continue to believe that the vaccine is contributing to autism," said study author Dr. Anjali Jain, of The Lewin Group, a health care consulting firm in Falls Church, Virginia.

"In a nutshell, the answer is no, the vitamin pills do not reduce cancer risk," said the author of the analysis, Dr. Tim Byers, of the University of Colorado Cancer Center. For example, in a study published in 2006 in the American Journal of Clinical Nutrition, researchers found that women who had a high intake of folic-acid supplements had a 19 percent greater risk of breast cancer than those who did not take such supplements. Moreover, women who had the highest levels of folate, the water-soluble form of folic acid, in their blood had a 32 percent greater risk of breast cancer than those who had the lowest levels.
