Microsoft laid off an entire team dedicated to guiding AI innovation that leads to ethical, responsible and sustainable outcomes. The cutting of the ethics and society team, as reported by Platformer, is part of a recent spate of layoffs that affected 10,000 employees across the company.

The elimination of the team comes as Microsoft invests billions more dollars into its partnership with OpenAI, the startup behind art-and text-generating AI systems like ChatGPT and DALL-E 2, and revamps its Bing search engine and Edge web browser to be powered by a new, next-generation large language model that is “more powerful than ChatGPT and customized specifically for search.”

The move calls into question Microsoft’s commitment to ensuring its product design and AI principles are closely intertwined at a time when the company is making its controversial AI tools available to the mainstream.

Will the global resources be ready to accommodate the world’s dietary needs?

Exploiting the natural and energy resources of the moon and asteroids can spark a space-based industrial revolution that could be a boon to all humankind. Pure science alone will be enough reason for the people who pay the bills to finance space exploration. Accessing the wealth that exists beyond the Earth is more than enough incentive for both public and private investment. Science will benefit. Someone will have to prospect for natural and energy resources in space and to develop safe and sustainable ways to exploit it.

Conflict between scientists and commercial space is already happening. Astronomers complain that SpaceX’s Starlink satellite internet constellation is ruining ground-based observation. Some critics fear that commercial exploitation of the moon’s resources will impede the operation of telescopes on the far side of the moon.

In an exciting turn for the field of sustainable energy research, Australian scientists have found a way to make energy out of thin air. Literally.

As detailed in a new study published this week in the journal Nature, researchers from Monash University in Melbourne, Australia discovered a new bacterial enzyme that transforms the traces of hydrogen in our atmosphere into electricity, technology that could one day be used in fuel cells that power anything from a smartwatch to even a car.

“We’ve known for some time that bacteria can use the trace hydrogen in the air as a source of energy to help them grow and survive, including in Antarctic soils, volcanic craters, and the deep ocean,” said Professor Chris Greening, a contributor to the study, in a statement.

A Norwegian Greentech company has recently unveiled its new 1,000-foot (324m) tall, floating wind turbine array. Called “Wind Catcher”, this innovation in renewable energy generation could be used to power as many as 80,000 homes.

The system has been developed by the Norwegian-based Wind Catching Systems (WCS), who declare that their new wind turbine setup could generate five times the annual energy of the world’s biggest standalone wind turbines. Not only that, but if scaled, it could reduce the costs of wind energy to be competitive with traditional grid-supplied electricity.

Companies could one day make superconductive quantum computer chips that function at room temperature thanks to a new material from researchers in the US. Ranga Dias from the University of Rochester and colleagues made a material superconductive at 21°C and pressures less than 1% of those used for existing high-temperature superconductors. ‘The most exciting part is the pressure,’ Dias tells Chemistry World. ‘Even I didn’t think this was possible.’

Together with Ashkan Salamat’s team at the University of Nevada, Las Vegas, the scientists say that electrical resistance in their nitrogen-doped lutetium hydride falls to zero at room temperature. Making room-temperature zero-resistance materials is a chemistry ‘holy grail’ and could fight climate change by reducing the 5% of electricity lost as heat while flowing through the grid.

However, Dias and Salamat’s team hasn’t been able to fully confirm the new material’s structure. As hydrogen atoms are so small they don’t easily diffract the x-rays used to work out the material’s composition. And this is an important reservation, considering the publisher of the team’s previous high-temperature superconductor paper retracted it.

Since the advent of quantum mechanics, the field of physics has been divided into two distinct areas: classical physics and quantum physics. Classical physics deals with the movements of everyday objects in the macroscopic world, while quantum physics explains the strange behaviors of tiny elementary particles in the microscopic world.

Many solids and liquids are made up of particles that interact with each other at close distances, leading to the creation of “quasiparticles.” Quasiparticles are stable excitations that act as weakly interacting particles. The concept of quasiparticles was introduced in 1941 by Soviet physicist Lev Landau and has since become a crucial tool in the study of quantum matter. Some well-known examples of quasiparticles include Bogoliubov quasiparticles in superconductivity, excitons in semiconductors.

Researchers are coming to understand that the best performing materials in sustainable energy applications, such as converting sunlight or waste heat to electricity, often use collective fluctuations of clusters of atoms within a much larger structure. This process is often referred to as “dynamic disorder.”

Understanding dynamic disorder in materials could lead to more energy-efficient thermoelectric devices, such as solid-state refrigerators and heat pumps, and also to better recovery of useful energy from waste heat, such as car exhausts and power station exhausts, by converting it directly to electricity. A thermoelectric device was able to take heat from radioactive plutonium and convert it to electricity to power the Mars Rover when there was not enough sunlight.

“Now is the moment for a rigorous portrait of Elon Musk.”

Alex Gibney, an award-winning filmmaker, is working on a new documentary about Elon Musk. The movie “Musk” aims to be “a definitive and unvarnished investigation” of the multibillionaire CEO of SpaceX, Tesla, and Twitter. The project has been in the works for months.

Other documentaries by Gibney have explored topics such as Steve Jobs, Enron, WikiLeaks, Elizabeth Holmes, Scientology, and more.
