‘Curious and curiouser!’ Meteorite chunk contains unexpected evidence of presolar grains

Posted by in categories: materials, space travel

An unusual chunk in a meteorite may contain a surprising bit of space history, based on new research from Washington University in St. Louis.

Presolar —tiny bits of solid interstellar material formed before the sun was born—are sometimes found in primitive meteorites. But a new analysis reveals evidence of presolar grains in part of a where they are not expected to be found.

“What is surprising is the fact that presolar grains are present,” said Olga Pravdivtseva, research associate professor of physics in Arts & Sciences and lead author of a new paper in Nature Astronomy. “Following our current understanding of solar system formation, presolar grains could not survive in the environment where these inclusions are formed.”

Very predictable since China started offering data. It projects to 16k infected Fri and 88k next Mon Feb 3.

Does the mkt understand this growth rate? Or will it freak?

Northrop Grumman Awarded DARPA Hypersonic Missile Defense Contract

Posted by in category: military

Northrop Grumman was awarded a $13 million contract from the U.S. Defense Advanced Research Projects Agency (DARPA) for the Glide Breaker program. The contract provides for the research, development, and demonstration of a technology that is critical for enabling an advanced interceptor capable of engaging maneuvering hypersonic threats in the upper atmosphere.

The U.S. is bolstering its investment in hypersonic weapons, and all the major services are participating in various development programs in conjunction with DARPA. The additional objective is protecting against hypersonic weapons other countries are developing.

The Glide Breaker program was launched in 2018 as part of this hypersonic missile defense effort. This particular project is intended to defend against boost glide vehicles, which are glide bodies lofted into the atmosphere on a ballistic missile. The glide body separates from the missile and glides unpowered to its target, with the ability to maneuver and follow unpredictable flight patterns. This maneuvering capability is one of the factors that makes these types of weapons harder to defend against than traditional ballistic missiles that follow predictable ballistic trajectories.

Moss-growing concrete absorbs CO2, insulates and is also a vertical garden

Posted by in categories: biological, climatology, sustainability

Buildings with this concrete can—in regions with a calm mediterranean climate—absorb CO2 and release oxygen with micro-algae and the other “pigmented microorganisms” that coat it. These vertical gardens boast aesthetic appeal, but the biological concrete’s beauty also lies in its clever design.

The concrete works in layers. The top layer absorbs and stores rainwater and grows the microorganisms underneath. A final layer of the concrete repels water to keep the internal structure safe. The top can also absorb solar radiation, which insulates the building and regulates temperatures for the people inside.

5 Big Ideas for Making Fusion Power a Reality

Posted by in categories: humor, nuclear energy, particle physics

After decades of not happening, fusion power finally appears to be maybe possibly happening.


The joke has been around almost as long as the dream: Nuclear fusion energy is 30 years away…and always will be. But now, more than 80 years after Australian physicist Mark Oliphant first observed deuterium atoms fusing and releasing dollops of energy, it may finally be time to update the punch line.

Over the past several years, more than two dozen research groups—impressively staffed and well-funded startups, university programs, and corporate projects—have achieved eye-opening advances in controlled nuclear fusion. They’re building fusion reactors based on radically different designs that challenge the two mainstream approaches, which use either a huge, doughnut-shaped magnetic vessel called a tokamak or enormously powerful lasers.
