The Air Force’s mystery space plane is back on Earth, following a record-breaking two-year mission.

The X-37B landed at NASA’s Kennedy Space Center in Florida early Sunday. The Air Force is mum about what the plane did in orbit after launching aboard a SpaceX rocket in 2017. The 780-day mission sets a new endurance record for the reusable test vehicle.

It looks like a but is one-fourth the size at 29 feet.

Prostate cancer runs in Jeff Nelson’s family. His brother, uncle and cousins have all been diagnosed with the disease. When his prostate-specific antigen (PSA) test results jumped to 5.5 from 4 in summer 2018, he knew he had to move quickly.


Jeff Nelson chose UCI Health and an investigative treatment for prostate cancer that uses high-intensity sound waves to destroy only the cancer tissue. He’s glad he did.

Structured light is a fancy way to describe patterns or pictures of light, but deservedly so as it promises future communications that will be both faster and more secure.

Quantum mechanics has come a long way during the past 100 years but still has a long way to go. In AVS Quantum Science researchers from the University of Witwatersrand in South Africa review the progress being made in using structured light in quantum protocols to create a larger encoding alphabet, stronger security and better resistance to noise.

“What we really want is to do quantum mechanics with ,” said author Andrew Forbes. “By this, we mean that light comes in a variety of patterns that can be made unique—like our faces.”
