Dark Matter Birthed More of Itself From Regular Matter, Claims Wild New Paper

Posted by in categories: cosmology, particle physics

There’s a lot we still don’t know about dark matter – that mysterious, invisible mass that could make up as much as 85 percent of everything around us – but a new paper outlines a rather unusual hypothesis about the very creation of the stuff.

In short: dark matter creates dark matter. The idea is that at some point in the early stages of the Universe, dark matter particles were able to create more dark matter particles out of particles of regular matter, which would go some way to explaining why there’s now so much of the stuff about.

The new research builds on earlier proposals of a ‘thermal bath’, where regular matter in the form of plasma produced the first bits of dark matter – initial particles which could then have had the power to transform heat bath particles into more dark matter.

How COVID-19 mRNA Vaccines Work — Vaccine Makers Project

Posted by in categories: biotech/medical, education

Great video of vital biomolecular processes.


COVID-19 mRNA vaccines deliver directions to make a protein that educates our immune system, so it will neutralize the virus in future encounters. The mRNA-containing lipid particles are taken up by specialized immune system cells. See more: COVIDVaccineAnswers.org

Can Spinlaunch Throw Rockets Into Space?

Posted by in categories: engineering, space travel

With the recent COP talks in mind, is this the Eco alternative to rocketry? And are there perhaps others?


I talked about Spinlaunch a few years ago, they wanted to reduce space launch costs by throwing the launch vehicles out of a spinning launcher at hypersonic speeds. I was somewhat skeptical as to the chances of solving the engineering problems inherent in this, but recently they demonstrated a mach 1 launch using their 1/3 scale launcher, so they’re already making progress on developing a viable launch syste.

Tardigrades: Why water bears could be the first interstellar astronauts

Posted by in categories: health, robotics/AI, space

It’s more likely than you think.


When it comes to interstellar missions, however, there are no plans for crewed missions on the table. While there are proposals for sending robotic missions, sending astronauts to nearby stars and exoplanets simply isn’t feasible yet.

Watch: Black hole 11 times bigger than the Sun discovered among young stars

Come out, come out, wherever you are!


In a neighboring star cluster called NGC 1,850, astronomers spotted a small black hole tugging on the orbit of a star — a discovery that could lead us to others.

Bias in A.I. is a big, thorny, ethical issue

Posted by in category: robotics/AI

Companies like Facebook parent Meta and Google parent Alphabet have all experienced major A.I. bias blunders, sometimes involving computer vision technology misidentifying Black people with primates. Numerous high-profile academic studies, articles in mainstream news outlets, and proposed regulations by lawmakers in the European Union and elsewhere continue to bring the issue to the forefront.

On a personal note, I’ve lost count of the number of times I’ve had to write variations of the phrase “facial recognition software that works better on white males than women and people of color” in articles about A.I. bias.

4 Ways Successful Enterprises Are Driving Success In AI

Posted by in categories: business, employment, robotics/AI

Many companies are experimenting with AI, often in many different areas of the company. But experimentation is not enough. It’s essential to have a bold corporate strategy driven from the top. The AI strategy needs to be coordinated throughout the company in tight alignment with the overall business strategy.

AI can be scary for employees, and many are worried about their jobs (see another jobs?). The most successful AI-fueled organizations lead with change management to enable AI systems to succeed.

A key factor for successful change management is trust. Companies that focus on relationship-building, collaboration, and training engender trust. Successful companies help employees understand that most AI replaces tasks, not jobs. Those companies are aiming to augment jobs so that AI and employees work together. If AI is going to replace jobs, management needs to be clear about exactly how that will play out for the employees and provide opportunities for them to upskill or reskill.
