It doesn’t have to be all fun and games in the Metaverse, especially when its best use cases are the ones that need a different reality the most. Thanks to a few companies that have large marketing machines, the word “Metaverse” has become muddled in hype and controversy. While the current use of the coined word might be new to our ears, the technologies that empower it have been around for quite some time now. And they aren’t always used for games or entertainment, even if that is what everyone thinks these days. In fact, one of the most frequent early adopters of these technologies come from the medical field, which continuously tests new equipment, theories, and digital experiences to help improve lives. So while mainstream media, carmakers, and social networks continue to shine the light on new ways to experience different worlds, the Metaverse, its concepts, and its applications are already sneaking their way into medical and scientific institutions, ready to take healthcare to the next, augmented reality level.

San Mateo, California — A California startup is doing its part to cut down on greenhouse gas emissions by creating a new kind of “meat” that’s made from air.

CBS News was given an exclusive sneak peak at a product that physicist Lisa Dyson says has the taste and texture of meat, but does not come from animals. It’s created using a fermentation process, similar to making yogurt. But instead of using microbes that consume milk and sugar, it’s made from microbes that eat oxygen, nitrogen and carbon dioxide.

How does it work?

Earthquakes do more than buckle streets and topple buildings. Seismic waves generated by earthquakes pass through the Earth, acting like a giant MRI machine and providing clues to what lies inside the planet.

Seismologists have developed methods to take wave signals from the networks of seismometers at the Earth’s surface and reverse engineer features and characteristics of the medium they pass through, a process known as seismic tomography.

Back in 2018, researchers were able to study the moment brain death becomes irreversible in the human body for the first time, observing the phenomenon in several Do Not Resuscitate patients as they died in hospital.

For years, scientists have researched what happens to your brain when you die, but despite everything we’ve found out, progress has been stymied by an inability to easily monitor human death – since physicians are conventionally obliged to prevent death if they can, not monitor it as it takes hold.

What this means is most of our understanding of the processes involved in brain death come from animal experiments, strengthened with what we can glean from the accounts of resuscitated patients disclosing their near-death experiences.

New treatment options for neuronal diseases require better imaging techniques that will help find which patients will benefits from these treatments.

Every time a new cancer drug is announced, it represents hundreds of researchers spending years behind the scenes working to design and test a new molecule. The drug has to be not only effective, but also as safe as possible and easy to manufacture—and these researchers have to choose among thousands of possible options for its chemical structure.

But building each possible molecular structure for testing is a laborious process, even if researchers simply want to change a single carbon atom.

A new technique published by University of Chicago chemists and the pharmaceutical company Merck & Co. in the journal Science offers a way to leapfrog that process, allowing scientists to quickly and easily produce new molecules of interest.

A group of 60 scientists called for a moratorium on solar geoengineering last month, including technologies such as stratospheric aerosol injection (SAI). This involves a fleet of aeroplanes releasing aerosol particles – which reflect sunlight back to outer space – into the atmosphere, cooling down the Earth.

SAI might make the sky slightly whiter. But this is the least of our concerns. SAI could pose grave dangers, potentially worse than the warming it seeks to remedy. To understand the risks, we’ve undertaken a risk assessment of this controversial technology.

A cooler Earth means less water would be evaporating from its surfaces into the atmosphere, changing rainfall patterns. This could produce ripple effects across the world’s ecosystems – but the exact nature of these effects depends on how SAI is used. Poor coordination of aerosol release could lead to extreme rainfall in some places and blistering drought in others, further triggering the spread of diseases.
