Our nation's veterans continue to suffer emotional and psychological effects of war--some for decades. And while there has been greater attention directed recently toward post-traumatic stress disorder (PTSD), and more veterans are seeking help, current psychotherapy treatments are less than optimal, according to a new narrative review.

A new patient sits across from me in the exam room, confused and frustrated at her lack of progress trying to lose weight for the last 30 years. 200 pounds too heavy, diagnosed with type 2 diabetes, high cholesterol, hypertension, sleep apnea, infertility and osteoarthritis. She needs knee replacements, but is too heavy to be approved for the surgery.

By:  Karin Heineman, Inside Science TV – Viruses: they’re too tiny for us to see, yet they’re lurking everywhere.  And guess what? They spread really fast through an office environment.

“Most people don’t realize they easily spread by your hands,” said University of Arizona microbiologist Charles Gerba. Most people think that viruses spread by inhaling sick people’s coughs or sneezes, but “it’s really when those droplets settle out and you touch that surface” that tiny viruses spread, he said. People unknowingly bring their virus-covered fingers to their noses, mouths, or eyes, kicking off infection.

Wolves and foxes are closely related and share many of the same characteristics.

But look at their eyes – where wolves have rounded pupils like humans, foxes instead have a thin vertical line.

But it isn’t just canines –across the animal kingdom, pupils come in all shapes and sizes. So why the differences?

It’s a question that has long interested scientists working on vision and optics. In a new study published in the journal Science Advances, colleagues from Durham, Berkeley and I explain why these pupil shapes have developed.

So, I get in a pissy mood once in a while. Before you judge, you try taking the Times Square-Grand Central Station shuttle every day. See what kind of mood you end up in:

Then I read something so infuriatingly stupid in the Huffington Post — which is of questionable value even on a good day — that my already-sour disposition headed even further south.

Democrats (myself included) enjoy ridiculing Republicans who deny the scientific consensus behind climate change. But we then deny the inconvenient truth behind our own preferred climate policies: they will have regressive impacts on the poor and middle class.

The Energy Information Agency (EIA) projected in May that President Obama’s new Clean Power Plan (CPP) will lead to retail electricity prices 3%-7% higher for the nation as a whole in 2020-25, before falling to “near-baseline” levels in 2030. Yet speaking in the White House on August 3, the president denied the CPP would “cost you more money.”

Scientists on the NuMI Off-Axis Electron Neutrino Appearance (NOvA) experiment saw their first evidence of oscillating neutrinos, confirming that the extraordinary detector built for the project not only functions as planned but is also making great progress toward its goal of a major leap in our understanding of these ghostly particles.

The New York City subway system is notorious for its filth and grime, something that was captured well in Jonath Hertzberg’s 2013 video essay, titled Dirty Old New York Subway, which cataloged the trains’ cinematic history.

Cancer survival in England remains lower than countries with similar healthcare systems, according to a new study. Cancer survival in England has steadily improved but the gap in survival remains.

The research, from the London School of Hygiene&Tropical Medicine, compared survival for colon, breast, lung, ovarian, rectal and stomach cancers in England, Australia, Canada, Denmark, Norway and Sweden between 1995 and 2009, and survival trends in England up to 2012. It included more than 1.9 million cancer patients in England and another 1.9 million cancer patients from the other five countries. The report analyzed data from Australia, Canada, Denmark, Norway and Sweden between 1995 and 2009 and data from England between 1995 and 2012.

Patients with low testosterone levels who have then gone on to have testosterone replacement therapy (TRT) could be at lower risk of cardiovascular events such as heart attack or stroke, according to research published today (Thursday) in the European Heart Journal.

In the study, researchers from Kansas City VA Medical Centre in Kansas City, USA, examined the effect of TRT on cardiovascular outcomes by comparing incidences of heart attack, stroke, and all-cause mortality among different sub-populations of treated and untreated patients. The study used the largest cohort of patients and the longest follow-up for TRT to date.
