The Air Force’s top general appeared to be losing his cool. But it wasn’t over a controversial plan to scrap an aircraft prized for protecting ground troops or billions of dollars in cuts that are straining a service striving to recover from the grind of 12 years of war.
“The single biggest frustration I’ve had in this job is the perception that somehow there is religious persecution inside the United States Air Force,” Gen. Mark Welsh III told a House Armed Services Committee hearing earlier this spring. “It’s not true.”

Matter will be created from light within a year, claim scientists
Researchers have worked out how to make matter from pure light and are drawing up plans to demonstrate the feat within the next 12 months.
The theory underpinning the idea was first described 80 years ago by two physicists who later worked on the first atomic bomb. At the time they considered the conversion of light into matter impossible in a laboratory.
But in a report published on Sunday, physicists at Imperial College London claim to have cracked the problem using high-powered lasers and other equipment now available to scientists.
California wildfire increase linked to climate change
Drought-stricken California is preparing for its worst wildfire season ever, the state's governor said on Sunday.
Governor Jerry Brown told ABC's This Week that the nearly dozen wildfires that this week caused more than $20m in damage mark only the beginning. The state has 5,000 firefighters and has appropriated $600m to battling blazes, but that may not be enough.
"We're getting ready for the worst," Brown said. "Now, we don't want to anticipate before we know, but we need a full complement of firefighting capacity."
Investigators race to find victims of child pornography
The expansion of the "Dark Web," where pedophiles hide using websites that encrypt their computers' identifying information, has fueled an explosion of child pornography that has law enforcement in a race against time to find victims before they are abused again.
Investigators follow the trail of images around the world any way they can. They rely on traditional detective techniques, such as interviewing suspects, but they also use modern-day digital methods. They enhance blurry backgrounds for clues to a photo's location. They monitor websites popular with pedophiles. They use social media to blast photos of suspected child pornographers in the hope that someone will recognize them.
PlayStation 4 And Xbox One Are Energy Hogs
For all their graphical improvements and multimedia functionality, there's one place where Microsoft's Xbox One and Sony's PlayStation 4 are sorely lacking: energy efficiency.
This is according to a report released on Thursday from the Natural Resources Defense Council (NRDC), which found that both the Xbox One and the PlayStation 4 consume two to three times more electricity than the previous generation of consoles. The Nintendo Wii U is the only next-gen console that consumes less energy than the Wii that came before it, the NRDC found.
Drug can reduce HIV infection rates by more than 90 percent
New guidelines published by the Centers for Disease Control and Prevention in Atlanta recommend daily drug therapy for people who are at high risk for contracting HIV.
The U.S. Public Health Service recommends doctors evaluate their male and female patients who are sexually active and at high risk of contracting human immunodeficiency virus or who are injecting illicit drugs, and consider offering Pre-Exposure Prophylaxis for HIV Prevention as a prevention option.
The federal guidelines recommend PrEP be considered for those who are HIV-negative, but at substantial risk for HIV, such as a person who is in an ongoing relationship with an HIV-positive partner, or heterosexual people who do not regularly use condoms during sex with partners of unknown HIV status.
Silently among us: Scientists worry about milder cases of MERS
Scientists leading the fight against Middle East Respiratory Syndrome say the next critical front will be understanding how the virus behaves in people with milder infections, who may be spreading the illness without being aware they have it.
Establishing that may be critical to stopping the spread of MERS, which emerged in the Middle East in 2012 and has so far infected more than 500 patients in Saudi Arabia alone. It kills about 30 percent of those who are infected.
The people of Miami know about climate change. We're living it
Clear skies above but water below, a woman on a moped navigates a flooded street corner on Miami Beach, an all-too-familiar sign for residents of this iconic peninsula where the ocean seems more likely than ever to swamp Ocean Drive one day.
If there's an image that starkly illustrates the threats of climate change, it's this photograph, which was included in the recent National Climate Assessment released by the White House. It is noteworthy because the flood is from exceptionally high spring tides – not heavy rains. Tidal flooding like that is relatively new. And scary. "People in Miami Beach are living climate change," said David Nolan, a meteorology and physical oceanography professor at the University of Miami. "They're on the frontline."
NAACP names new president on Brown v Bd. of Education anniversary
The National Association for the Advancement of Colored People has announced the appointment of a new president, marking Saturday's 60th anniversary of the landmark Brown vs Board of Education supreme court decision.
The announcement came two weeks after the organisation was drawn into the furore over Donald Sterling, the owner of the Los Angeles Clippers NBA franchise.
Cornell William Brooks, a New Jersey lawyer and activist, will become the 18th NAACP national president, replacing Lorraine Miller, who has lead the organisation since Benjamin Jealous stepped down last year.
