Laser mining – the light at the end of the tunnel?

Posted by in categories: chemistry, engineering, government

Laser mining would allow for a no explosive option and not need huge machines increasing output as well. Also lasers could make more precise cuts rather than blades which would never get dull.


The application of the “Graduated Optical Colimator” (GOC) for the mining industry consists of a one-kilowatt optical power fiber laser to selectively spall igneous geological formations containing narrow veins of precious metals.

Scientist Says Astronauts Should Take Psychedelic Mushrooms in Space

Posted by in categories: engineering, environmental, space

Do you agree?


In the future, when space agencies start to send human crews deep into space to explore or terraform distant worlds, we may need to send them off with extra goodies to keep morale high.

When astronauts are feeling lonely, depressed, traumatized, or just generally bad, a little pick-me-up in the form of psychedelic mushrooms could help, mycologist Paul Stamets suggested to Scientific American. It’s an odd idea, but as the body of evidence continues to grow that psilocybin — the active ingredient in shrooms — may have myriad mental health benefits, it may be an odd idea worth considering.

Bio-Inspired, Blood-Repelling Tissue Glue Can Seal Wounds Quickly and Stop Bleeding

Posted by in categories: biotech/medical, engineering

When the resulting paste is applied to a wet surface such as blood-covered tissue, the oil repels the blood and other substances that may be present, allowing the adhesive microparticles to crosslink and form a tight seal over the wound. Within 15 to 30 seconds of applying the glue, with gentle pressure applied, the glue sets and bleeding stops, the researchers showed in tests in rats.


A new adhesive that mimics the sticky substance barnacles use to cling to rocks may offer a better way to treat traumatic injuries.

With a single photo, SpaceX sent a not-so-subtle message to FAA regulators

Posted by in categories: engineering, finance, government, space travel

And ArsTechnica seems to be totally missing the point as “delaying” Starship for SOUND AND PRACTICAL SAFETY AND ENVIRONMENTAL QUESTIONS is not ‘delaying’ progress and one needs to simply ask why SpaceX “engineers” can’t up their game enough to actually answer or address those legitimate questions? The answer is rather simple, they probably CAN but the person “in charge” has no with to, incentive to, or will to do so because he sees anyone that questions him as ‘unreasonable opposition’ rather than legitimate concern. Starship could crash and burn on the orbital flight and it would not make a difference at all to the ‘world’ in general. We can and have recovered from worse numerous times while advancing technology and transportation. The FACT that Musk, (and his many rapid fans) somehow “assume” that he and only he can ‘advance’ space access are very much proof that this is not about engineering, ability or purpose but strictly about ego.


To the FAA, Musk seemed to be saying, federal regulators must do their part to ensure the future arrives on schedule. Just as the 20th-century skyscrapers marked the beginning of a new era and eventually launched America into a prosperous future of finance, communication, marketing, and more, the 21st century now beckons.

The skyscraper age will soon give way to the space age.

MIT Researchers Devised a Way To Program Memories Into Bacterial Cells

Posted by in categories: biotech/medical, chemistry, engineering

For several years, Lu’s lab has been working on ways to use DNA to store information such as memory of cellular events. In 2,014 he and Farzadfard developed a way to employ bacteria as a “genomic tape recorder,” engineering E. coli to store long-term memories of events such as a chemical exposure.


Technique for editing bacterial genomes can record interactions between cells, may offer a way to edit genes in the human microbiome.

A few steps closer to Europa: Spacecraft hardware makes headway

Posted by in categories: engineering, space

Take a closer look at the complex choreography involved in building NASA’s Europa Clipper as the mission to explore Jupiter’s moon Europa approaches its 2,024 launch date.

The hardware that makes up NASA’s Europa Clipper is rapidly taking shape, as engineering components and instruments are prepared for delivery to the main clean room at the agency’s Jet Propulsion Laboratory in Southern California. In workshops and labs across the country and in Europe, teams are crafting the complex pieces that make up the whole as mission leaders direct the elaborate choreography of building a flagship mission.

The massive 10-foot-tall (3-meter-tall) propulsion module recently moved from NASA’s Goddard Space Flight Center in Greenbelt, Maryland, to the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, where engineers will install electronics, radios, antennas, and cabling. The spacecraft’s thick aluminum vault, which will protect Europa Clipper’s electronics from Jupiter’s intense radiation, is nearing completion at JPL. The building and testing of the science instruments at universities and partner institutions across the country continue as well.

Using graphene foam to filter toxins from drinking water

Posted by in categories: chemistry, engineering, health, nuclear energy, sustainability

Some kinds of water pollution, such as algal blooms and plastics that foul rivers, lakes, and marine environments, lie in plain sight. But other contaminants are not so readily apparent, which makes their impact potentially more dangerous. Among these invisible substances is uranium. Leaching into water resources from mining operations, nuclear waste sites, or from natural subterranean deposits, the element can now be found flowing out of taps worldwide.

In the United States alone, “many areas are affected by uranium contamination, including the High Plains and Central Valley aquifers, which supply drinking water to 6 million people,” says Ahmed Sami Helal, a postdoc in the Department of Nuclear Science and Engineering. This contamination poses a near and present danger. “Even small concentrations are bad for human health,” says Ju Li, the Battelle Energy Alliance Professor of Nuclear Science and Engineering and professor of materials science and engineering.

Now, a team led by Li has devised a highly efficient method for removing uranium from drinking water. Applying an electric charge to graphene oxide foam, the researchers can capture uranium in solution, which precipitates out as a condensed solid crystal. The foam may be reused up to seven times without losing its electrochemical properties. “Within hours, our process can purify a large quantity of drinking water below the EPA limit for uranium,” says Li.

What You Need to Know About Solid-State Batteries

Posted by in categories: computing, engineering, mobile phones, sustainability, transportation

This next jump in battery-tech could solve a lot of EV problems.


The world of the internal combustion engine will sadly, but very necessarily, come to a close at some point in many of our lifetimes. Hybrids and electric vehicles are becoming more affordable and more advanced at a rapid pace, which means batteries are taking the place of fossil fuels. This has led to an equally rapid progression in battery technology, with the main goals of improving capacity, charging times, and safety. One major advancement in this field is the advent of solid-state batteries, which promise to push the boundaries of the limitations that current lithium-ion batteries carry.

Researchers discover new strategy for developing human-integrated electronics

Posted by in categories: biotech/medical, chemistry, engineering, health

Polymer semiconductors—materials that have been made soft and stretchy but still able to conduct electricity—hold promise for future electronics that can be integrated within the body, including disease detectors and health monitors.

Yet until now, scientists and engineers have been unable to give these polymers certain advanced features, like the ability to sense biochemicals, without disrupting their functionality altogether.

Researchers at the Pritzker School of Molecular Engineering (PME) have developed a new strategy to overcome that limitation. Called “click-to-polymer” or CLIP, this approach uses a chemical reaction to attach new functional units onto .
