But strangely, this green shade disappears before it reaches the one or two tails trailing behind the comet.

Astronomers, scientists, and chemists have been puzzled by this mystery for almost 90 years. In 1930, it was suggested that this phenomenon was due to sunlight destroying diatomic carbon. The carbon is created from the interaction between sunlight and organic matter on the comet’s head. However, due to the instability of dicarbon, this theory has been hard to test.

Scientists at UNSW Sydney have finally found a way to test this chemical reaction in a laboratory – and in doing so, has proven this 90-year-old theory correct. They solved this mystery with the help of a vacuum chamber, a lot of lasers, and one powerful cosmic reaction.

However, the weather in French Guiana isn’t looking good.

Block CEO Dorsey has consistently praised bitcoin, and his departure as Twitter’s CEO is likely linked to his ambitions around the crypto asset.

Scientists have identified unique “indicators” in the blood of patients with severe and fatal Covid, paving the way for simple diagnostic tests to help doctors identify who will go on to become critically ill.

Exactly six years after its first successful recovery, SpaceX has landed a Falcon booster for the 100th time.

On December 21st, 2015, the first Falcon 9 V1.2 Full Thrust (Block 1) rocket lifted off from SpaceX’s Cape Canaveral LC-40 launch pad on the company’s return-to-flight mission after a catastrophic in-flight failure just six months prior. Unwilling as ever to waste an opportunity, no matter how important the mission, SpaceX – on top of debuting a major Falcon 9 upgrade – chose to take advantage of the return to flight to attempt to land a Falcon booster back on land for the first time ever. Ultimately, on top of successfully deploying multiple Orbcomm OG2 communications satellites in orbit for a paying customer, Falcon 9 booster B1019 sailed through its boostback, reentry, and landing burns without issue. About nine minutes after liftoff, the rocket ultimately touched down on a concrete “landing zone” just a few miles from where it lifted off with uncanny ease relative to SpaceX’s numerous failed attempts in the ~18 months prior.

Exactly six years later, on December 21st, 2021, Falcon 9 booster B1069 lifted off from Kennedy Space Center (KSC) Pad 39A with an upgraded, flight-proven Cargo Dragon in tow for SpaceX’s 24th International Space Station (ISS) resupply mission. CRS-24 also marked the company’s 31st and final launch of 2021, representing more successful Falcon launches completed in a single year than SpaceX had even attempted in its entire nine-year history up to the point of that first successful booster landing.

Some engineered living materials can combine the strength of run-of-the-mill building materials with the responsiveness of living systems. Think self-healing concrete, paint that changes color when a specific chemical is detected or material that could reproduce and fill in a crack when one forms. This would revolutionize construction and maintenance, with wide-reaching economic and environmental implications.

Seeing this new category of adaptive materials on consumer shelves may be a ways off. Still, critical early research from the University of Minnesota sheds new light on this exciting advancement, which shows promise beyond building materials, including biomedical applications.

In a new study in Nature Communications, researchers from the College of Biological Sciences demonstrate how to transform silica — a common material used in plaster and other construction materials — into a self-assembling, dynamic and resilient material.

Multicoin, Alameda and the Solana Foundation are backing Render Network’s vision for a decentralized alternative to Pixar’s massive rendering farms.

More than a million Americans undergo knee and hip replacements each year. It’s a last resort treatment for pain and mobility issues associated with osteoarthritis, a progressive disease caused by degeneration of the protective layer of cartilage that stops our bones grinding together when we sit, stand, write, or move around.

But what if doctors could intervene and repair damaged cartilage before surgery is needed?

For the first time, researchers at the Keck School of Medicine of USC have used a stem cell-based bio-implant to repair cartilage and delay joint degeneration in a large animal model. The work will now advance into humans with support from a $6 million grant from the California Institute of Regenerative Medicine (CIRM).

Stepping into the Future.
