Electrolux GRO kitchen concept offers a fresh take on sustainable eating

Posted by in categories: food, sustainability

It’s no longer enough to just eat healthy. One also needs to make sure our healthy eating is also healthy for the planet. There has been a great deal of interest and attention given to diets in the past years, especially as people were forced to fend for themselves at home. Diet fads come and go, but the ingredients we use have mostly remained the same, and the demand for meat-based products has only gone higher, not lower. Our food system isn’t just broken, but so is our mindset and expectations of an unlimited supply of materials to feed the planet at the expense of the planet itself. That definitely has to change, and a holistic kitchen system imagines how tomorrow’s diets won’t only be plant-forward but also planet-friendly.

This desk microphone makes it painfully clear whether you are muted or not

Posted by in categories: computing, education

It’s amazing how simple designs can save you from hours of frustration and embarrassment, even virtually.

Work and School from Home arrangements have forced many people to get used to video meetings, virtual classrooms, and online presentations. As if those weren’t stressful enough already, the horrors of discovering that you have been speaking for the past 10 minutes to half an hour when you’re mic has been on mute all the time only adds to feelings of dread. Unfortunately, computers and software haven’t adjusted yet to these new demands on life, lacking clear indicators on the status of the mic. While there might be some sophisticated and complicated software that could try to guess whether you actually need to be muted or not, it actually takes a dead-simple idea to give that peace of mind at very little extra cost.

Solar energy can be cleanly converted into storable hydrogen fuel

Posted by in categories: climatology, solar power, sustainability

Greenhouse gas emissions need to be significantly reduced to avoid potentially catastrophic effects of climate change, with access to clean and affordable energy needed to eliminate our reliance on fossil fuels. Many researchers and companies are working to address this issue and replace fossil fuels through the use of hydrogen, a storable fuel.

When used in a fuel cell, hydrogen does not emit any greenhouse gasses at the point of use and can help decarbonize sectors such as shipping and transportation, where it can be used as a fuel, as well as in manufacturing industries. However, most hydrogen produced today is almost entirely supplied from natural gas and coal, producing greenhouse gases. And therefore, green hydrogen production is urgently needed.

New research led by the University of Strathclyde suggests that solar energy can be accessed and converted into hydrogen – a clean and renewable fuel.

James Webb Space Telescope hit by a micrometeoroid, larger than what NASA had anticipated

Between May 23 and 25, the James Webb Space Telescope (JWST) was hit by a micrometeoroid that has impacted one of its primary mirror segments, NASA said in a recent update on its website. The telescope continues to function at levels exceeding mission requirements.

A meteoroid is a fragment of an asteroid and can be either large or small. A micrometeoroid, though, is a microscopic fragment of a meteoroid and is smaller than a grain of sand. NASA estimates that millions of meteoroids and micrometeoroids strike the Earth’s atmosphere every day but most burn up due to the friction.

Theory suggests quantum computers should be exponentially faster on some learning tasks than classical machines

Posted by in categories: particle physics, quantum physics, robotics/AI

A team of researchers affiliated with multiple institutions in the U.S., including Google Quantum AI, and a colleague in Australia, has developed a theory suggesting that quantum computers should be exponentially faster on some learning tasks than classical machines. In their paper published in the journal Science, the group describes their theory and results when tested on Google’s Sycamore quantum computer. Vedran Dunjko with Leiden University City has published a Perspective piece in the same journal issue outlining the idea behind combining quantum computing with machine learning to provide a new level of computer-based learning systems.

Machine learning is a system by which computers trained with datasets make informed guesses about new data. And quantum computing involves using sub-atomic particles to represent qubits as a means for conducting applications many times faster than is possible with . In this new effort, the researchers considered the idea of running machine-learning applications on quantum computers, possibly making them better at learning, and thus more useful.

To find out if the idea might be possible, and more importantly, if the results would be better than those achieved on classical computers, the researchers posed the problem in a novel way—they devised a task that would learn via experiments repeated many times over. They then developed theories describing how a quantum system could be used to conduct such experiments and to learn from them. They found that they were able to prove that a quantum could do it, and that it could do it much better than a classical system. In fact, they found a reduction in the required number of experiments needed to learn a concept to be four orders of magnitude lower than for classical systems. The researchers then built such a system and tested it on Google’s Sycamore quantum computer and confirmed their theory.

Magnetizing laser-driven inertial fusion implosions

Posted by in categories: nuclear energy, particle physics

Nuclear fusion is a widely studied process through which atomic nuclei of a low atomic number fuse together to form a heavier nucleus, while releasing a large amount of energy. Nuclear fusion reactions can be produced using a method known as inertial confinement fusion, which entails the use of powerful lasers to implode a fuel capsule and produce plasma.

Researchers at Massachusetts Institute of Technology (MIT), University of Delaware, University of Rochester, the Lawrence Livermore National Laboratory, Imperial College London, and University of Rome La Sapienza have recently showed what happens to this implosion when one applies a strong to the fuel capsule used for . Their paper, published in Physical Review Letters, demonstrates that strong magnetic fields flatten the shape of inertial fusion implosions.

“In inertial confinement fusion, a millimeter-size spherical capsule is imploded using high-power lasers for ,” Arijit Bose, one of the researchers who carried out the study, told Phys.org. “Applying a magnetic field to the implosions can strap the charged plasma particles to the B-field and improve their chances of fusion. However, since magnetic field can restrict plasma particle motion only in the direction across the field lines and not in the direction along the applied field lines, this can introduce differences between the two directions that affect the implosion shape.”
