Circa 2015

As weapons get more sophisticated, researchers are trying to build defence systems that can keep pace, and what’s better than a force field?

Aerospace and defence giant Boeing has been awarded a patent to develop a force field-like system that could protect military vehicles from shockwaves following explosions from missiles or improvised explosive devices.

Boeing’s proposed system involves using a combination of lasers, electricity and microwaves to rapidly heat up the air between the vehicle and a blast. This heat creates a plasma shield that’s denser than the surrounding air and able to deflect or absorb the energy from the incoming shockwave.

Circa 2015

A researcher at Ransselaer Polytechnic Institute in the US has given three Nao robots an updated version of the classic ‘wise men puzzle’ self-awareness test… and one of them has managed to pass.

In the classic test, a hypothetical King calls forward the three wisest men in the country and puts either a white or a blue hat on their heads. They can all see each other’s hats, but not their own, and they’re not allowed to talk to each other. The King promises that at least one of them is wearing a blue hat, and that the contest is fair, meaning that none of them have access to any information that the others don’t. Whoever is smart enough to work out which colour hat they’re wearing using that limited information will become the King’s new advisor.

For example, less than an hour after CNBC first reported Gerstenmaier’s hiring, the head of Russian state space corporation Roscosmos, Dmitry Rogozin, tweeted his congratulations: “I wish my friend success in his new job!”

In his new position, Gerstenmaier is reporting to Hans Koenigsmann, the vice president of mission assurance at SpaceX. Although the role is officially a consultancy, it is expected to become a full-time position. SpaceX is poised to launch the first crewed mission of its Dragon spacecraft by June of this year. Gerstenmaier will play a key role in ensuring the safety of those missions and helping SpaceX secure certification for the Crew Dragon vehicle.

The hiring could have longer-term implications as well. Few people in the global aerospace community have as much gravitas as Gerstenmaier or as much understanding of how to build coalitions to explore space. As SpaceX seeks partners—including NASA—to work with it on developing Starship to take humans to the Moon and Mars, Gerstenmaier is well-positioned to offer advice, stitch together mission plans, and open key doors.

Wow… hmmm.

Scientists at Sanford Burnham Prebys Medical Discovery Institute have shown that two prebiotics, mucin and inulin, slowed the growth of melanoma in mice by boosting the immune system’s ability to fight cancer. In contrast to probiotics, which are live bacterial strains, prebiotics are “food” for bacteria and stimulate the growth of diverse beneficial populations. The study, published today in Cell Reports, provides further evidence that gut microbes have a role in shaping the immune response to cancer, and supports efforts to target the gut microbiome to enhance the efficacy of cancer therapy.

The research specifically opens new avenues to address important unmet clinical needs in , as it highlights the possible impact of prebiotics on growth control and therapy resistance.

“Earlier studies have demonstrated that prebiotics limit tumor growth, but until now the mechanism by which they do so has been unclear,” says Ze’ev Ronai, Ph.D., professor in Sanford Burnham Prebys’ Tumor Initiation and Maintenance Program and senior author of the study. “Our study shows for the first time that prebiotics limit cancer growth by enhancing anti-tumor immunity. The study supports further exploration of the potential benefits of prebiotics in treating cancer or augmenting current therapies.”
