Natural killer (NK) cells are lymphocytes, immune cells which have a powerful arsenal of cytotoxic weaponry that they can use against tumors.

Unfortunately, tumors protect themselves using a protective microenvironment that shields them from attack from NK cells. This microenvironment promotes tumor growth and survival and has an immunosuppressive effect that blunts the attempts of NK cells to infiltrate the tumor and destroy it. That was until now and this new discovery.

Space tourism will take-off in 2018. As the race between spaceflight companies Virgin Galactic and SpaceX heats up, those who can afford it will be able to travel to low Earth orbit and possibly even around the moon.

In late 2018, tourists will be heading into space and there is a race on to get them there. Virgin Galactic will at last take paying customers beyond the stratosphere. But their efforts might be eclipsed by SpaceX, a company planning to send two tourists around the Moon. Taking them farther into space than any human since 1972.

There is a new breed of would-be astronauts for whom the sky is no limit. But it is not in everyone’s reach. Multi-millionaire entrepreneur, Per Wimmer will be one of the first tourists to go into space with private company, Virgin Galactic.

By sending quantum information several kilometers, the researchers took a big step toward the future of information security.

A team of Chinese researchers say they have completed the first long-distance quantum secure direct communication, a critical step toward sending messages that are truly safe from eavesdropping.

The information traveled 2.7 kilometers along a quantum channel, the team said in a paper that was peer-reviewed by China’s Science Bulletin journal and placed online Oct. 22.

Future U.S. military tanks may look and perform nothing like they do today.

In fact, they may not even have windows and instead seal military personnel inside a closed cockpit to better protect them against threats.

But how could they see the battlefield around them without windows? To see outside, Soldiers could use a new technology made by Honeywell that lets them “see” with virtual reality and augmented reality.

Today’s Sputnik moment is China’s rapid growth as an economic and technological superpower. In 2017 alone, China has outpaced the United States in renewable energy efforts and has become the standard-bearer in combating climate change and advocacy for globalization. Similarly, China is rapidly moving towards taking the lead in technology from the United States and is looking at quantum computing and artificial intelligence as areas for growth to do so.

The Verge recently published an article citing Alphabet chief executive officer Eric Schmidt’s perspective that the United States is falling behind when it comes to research and development in artificial intelligence, particularly compared to the rapid pace of innovation that China has set in the field. Schmidt, who is also the chair of the Defense Innovation Advisory Board, gave those remarks as part of a discussion at The Artificial Intelligence and Global Security Summit held by The Center for a New American Security (CNAS), a nonprofit think tank dedicated to research and analysis on how the United States can make informed policy-making decisions on national security and defense.
