This Rare Asteroid May Be Worth 70,000 Times the Global Economy. Now NASA Is Sending a Spaceship to Explore It

Posted by in categories: economics, space

A study published by The Planetary Science Journal in 2020 suggests that Psyche is made almost entirely of iron and nickel. This metallic composition sets it apart from other asteroids that are usually comprised of rock or ice, and could suggest it was originally part of a planetary core. That would not only represent a momentous discovery, it’s key to Psyche’s potential astronomical value: NASA scientist Lindy Elkins-Tanton calculated that the iron in the asteroid alone could be worth as much as $10 quintillion, which is $10,000,000,000,000,000,000 (yes, a 20-figure sum). For context, the entire global economy is worth roughly $110 trillion as of writing. However, more recent research out of the University of Arizona suggests that the asteroid might not be as metallic or dense as once thought. Psyche could actually be closer to a rubble pile, rather than an exposed planetary core, the research claims. If true, this would devalue the asteroid. NASA’s upcoming mission should settle the debate about Pysche’s composition for once and all.

Of course, Psyche isn’t the only valuable rock in space. NASA has previously said the belt of asteroids between Mars and Jupiter holds mineral wealth equivalent to about $100 billion for every individual on Earth. Mining the precious metals within each asteroid and successfully getting them back down to earth is the hard part. Then you have the whole supply and demand conundrum that could drive the price of specific metals up or down. We’ll leave the complexities of space mining for another day.

Tiny brain implant allows you to use social media with your mind

Posted by in categories: computing, Elon Musk, neuroscience

Scientists have developed a minuscule brain implant smaller than a human hair which allows people to control computers with their minds. The chip is developed by Precision Neuroscience and works along similar principles to those of Elon Musk’s Neuralink company, though the Precision chip sits on the brain rather than in the tissue.

Scientists find drug that can increase life span

Posted by in categories: biotech/medical, life extension

In a study from the University of Auckland, scientists found a drug that can increase life span. The age-old quest for immortality has taken a step forward. The team that long-term treatment of healthy mice from middle age (one year) with a drug currently used to treat cancer can increase their lifespan by an average of 10% to around three years.

U.S. Military Plans to Deploy Laser Weapons by 2025

Posted by in categories: drones, economics, military

The DEIMOS laser weapon is seen here in illustration, capable in the near future of knocking a drone, ordinance, aircraft and even missiles out of the sky.


It is the economics of laser weapon systems that makes this type of ordinance so attractive. At the moment various vendors like Lockheed Martin, and Raytheon are building 50 Kilowatt laser weapons. But there is no determining limit on the strength. The U.S. Department of Defense estimates a 100 Kilowatt laser could easily handle a drone, a small boat, a shell fired by artillery, and even a mortar. For a cruise missile, the estimate is a 300 Kilowatt laser, and for a ballistic missile or hypersonic weapon, a 1 Megawatt laser. Lockheed Martin is already testing a 300 Kilowatt version of DEIMOS.

The US Navy is looking at 100 Kilowatt versions of DEIMOS for its ships and looks like it will replace arming vessels with rail gun technology which now appears to be considered obsolete. Rail guns were high-speed ordinance systems designed to knock down incoming cruise missiles but when costs are compared the laser has the technology beat.

How a Brain Molecule Could Halt Multiple Sclerosis

Posted by in categories: biotech/medical, neuroscience

Summary: Injecting the brain molecule into mouse models of multiple sclerosis increased the number of oligodendrocytes. The findings suggest fractalkine may help to slow the progression, or potentially halt multiple sclerosis.

Source: University of Alberta.

A University of Alberta researcher is one step closer to demonstrating the potential of a brain molecule called fractalkine to halt and even reverse the effects of multiple sclerosis and other neurodegenerative diseases.

Rotating Detonation Rocket Engine: NASA’s Revolutionary Propulsion Design for Deep Space Missions

Posted by in category: space travel

NASA takes its first steps toward establishing a long-term presence on the Moon’s surface, a team of propulsion development engineers at NASA have developed and tested NASA’s first full-scale rotating detonation rocket engine, or RDRE, an advanced rocket engine design that could significantly change how future propulsion systems are built.

The RDRE differs from a traditional rocket engine by generating thrust using a supersonic combustion phenomenon known as a detonation. This design produces more power while using less fuel than today’s propulsion systems and has the potential to power both human landers and interplanetary vehicles to deep space destinations, such as the Moon and Mars.

Do we have a new Elizabeth Holmes?

To be fair, it seems JP Morgan was only able to check the emails after they acquired the platform since they were concerned about breaching data privacy prior to becoming its new legal caretakers.

Toroidal propellers: A noise-killing game changer in air and water

Posted by in categories: innovation, transportation

It’s rare to hear a new invention that has this much impact potential and doesn’t really need any more work to go commercial.


These strangely-shaped twisted-toroid propellers look like a revolutionary (sorry) advance for the aviation and marine sectors. Radically quieter than traditional propellers in both air and water, they’re also showing some huge efficiency gains.
