When a meteor strikes the earth, the havoc above ground is obvious, but the details of what happens below ground are harder to see. Duke University physicists have developed techniques that enable them to simulate high-speed impacts in artificial soil and sand in the lab, and then watch what happens underground close-up, in super slow motion.
They report that materials like soil and sand actually get stronger when they are struck harder.

Indoor radon levels in Pennsylvania have been slowly rising since 2004, around the time that unconventional natural gas development using hydraulic fracturing (“fracking”) began in the state. In our new study published in Environmental Health Perspectives, we found three pieces of evidence that there may be a link between unconventional natural gas development and indoor radon levels across the state.

Many scientists have studied fossils from gigantic marine lizards called mosasaurs that lived at the time of the dinosaurs and flourished in ancient seas, but little is known about aspects of their breeding and birth. Investigators have gained new insights from young mosasaur specimens collected over 100 years ago that had previously been thought to belong to ancient marine birds.

Uninsured cancer patients are asked to pay anywhere from 2 to 43 times what Medicare would pay for chemotherapy drugs, according to a new paper. Uninsured patients who did not negotiate the billed amounts could expect to pay $6,711 for an infusion of the colorectal cancer drug oxaliplatin. However, Medicare and private health plans only pay $3,090 and $3,616 for the same drug, respectively.

Melanoma, an aggressive form of skin cancer, has been increasing in incidence in adults over the past 40 years. Pediatric melanoma is rare (5-6 children per million) but some studies indicate that incidence has been increasing. In a new study scheduled for publication in The Journal of Pediatrics, researchers found that the incidence of pediatric melanoma in the United States actually has decreased from 2004-2010.

The Affordable Care Act (ACA) simultaneously forced young people to have health insurance and then forced insurance companies to allow them to stay on their parental policies until age 26 but the young people least likely to have it before still don't, according to a paper in the Journal of the American College of Surgeons.

Human norovirus may infect our canine companions. That raises the possibility of dog-to-human transmission, said first author Sarah Caddy, VetMB, PhD, MRCVS, a veterinarian and PhD student at the University of Cambridge, and Imperial College, London, UK.
Norovirus is the leading cause of food-borne illness in the United States, according to the Centers for Disease Control and Prevention (CDC).

Making small, consistent changes to the types of protein- and carbohydrate-rich foods we eat may have a big impact on long-term weight gain, according to a new study led by researchers at the Friedman School of Nutrition Science & Policy at Tufts University. The results were published on-line this week in The American Journal of Clinical Nutrition.

In 2012, PennFuture issued a report identifying fossil fuel tax credits in Pennsylvania totaling $2.9 billion, at the time roughly 10 percent of the state budget.
The environmental lobbying group has updated that report and the current dollar amount of tax incentives for the highly-profitable, mature fossil fuel industry continues to balloon at a time when the state faces a $1.5 billion budget shortfall and investment in emerging renewable energy industries are at fractional levels.
The new Senate looks to be no better than when Democrats were in charge, they note.
