NASA Says Hubble Observed a “Flapping Shadow” in Distant Space

Posted by in category: space

The star may be extremely young, but its ring of rock and dust is enormous. The size of just the shadow alone would be hundreds of times the size our entire solar system, according to NASA. Light would take more than a month to travel that distance.

By taking additional pictures using filters, the team was able to create a gorgeous, colored image of the star and its “bat shadow.”

Engineering an immunotherapy to outwit cancer — and launch a biotech

Posted by in categories: biotech/medical, engineering

Tweaking an immune protein called interleukin-18 can overcome tumors that lure it into binding with a decoy receptor protein and render it harmless to cancer cells, new research in mice shows. In conjunction with the paper, published Wednesday in Nature, a company founded by senior author Aaron Ring announced $25 million in initial financing to create and commercialize a drug based on the discovery.

The approach adds another weapon to an immunotherapy arsenal that activates immune responses hijacked by cancer. Checkpoint inhibitors, for example, take the brakes off immune cells that should battle invaders. IL-18 is a cytokine that normally activates T cells and natural killer cells, two immune forces that fight infection, but it’s disarmed by the decoy wielded by tumors.

Tesla Autopilot makes automatic lane change to avoid construction zone

Posted by in categories: robotics/AI, transportation

Tesla’s Full Self-Driving suite continues to improve with a recent video showing a Model 3 safely shifting away from a makeshift lane of construction cones while using Navigate on Autopilot.

Tesla owner-enthusiast Jeremy Greenlee was traveling through a highway construction zone in his Model 3. The zone contained a makeshift lane to the vehicle’s left that was made up of construction cones.

In an attempt to avoid the possibility of any collision with the cones from taking place, the vehicle utilized the driver-assist system and automatically shifted one lane to the right. This maneuver successfully removed any risk of coming into contact with the dense construction cones that were to the left of the car, which could have caused hundreds of dollars in cosmetic damage to the vehicle.

The Great Objection and its Confutation

Posted by in category: space

Before going to space, should we solve the problems here, on Earth?

Whenever we speak about human presence in space to a general audience, and quite often when we talk with specialists as well, we have to hear the Great Objection:” Before going to space, we have to solve our problems here, on the Earth”.

As soon as we reason about it we understand that the Objection is in fact a general dialectic scheme, which consists in changing the topic, pretending that the alternative is more important and urgent and so avoiding to reply to what the speaker has said. In short, it is a sort of quite-another-ism: “The problem is quite another, the cause is quite another…”.
