Researchers discover a “fossil cloud” that hasn’t been contaminated since the Big Bang

Making use of some of the most powerful telescopes on the planet, astronomers have found an ancient remnant of the Big Bang. This small piece of pure material from the early universe may provide light on the processes and motivations behind the formation of various star and galaxy types.

Using telescopes at the W. M. Keck Obervatory in Hawaii, a team of astronomers led by Fred Robert and Michael Murphy of the Swinburne University of Technology in Australia discovered a cloud of gas leftover from the Big Bang that was hiding far out in the universe. Behind the cloud, the telescope also discovered a quasar, which is an extremely bright active galactic nucleus that emits a lot of energy.

Combating carbon footprint: Novel reactor system converts carbon dioxide into usable fuel

Reducing carbon emissions from small-scale combustion systems, such as boilers and other industrial equipment, is a key step towards building a more sustainable, carbon-neutral future. Boilers are widely used across various industries for essential processes like heating, steam generation, and power production, making them significant contributors to greenhouse gas emissions.

Gluons, quarks, and the mystery of what makes a proton spin

For decades, nuclear physicists have been working to uncover the mysterious origins of the proton’s spin. According to a new study, they seem to have finally made some progress.

By combining experimental data with state-of-the-art calculations, researchers have revealed a more detailed picture of the spin contributions from the very glue that holds protons together, paving the way for imaging the proton’s 3D structure.

The mystery of the proton’s spin began in 1987 when measurements revealed that the proton’s building blocks, its quarks, only provide about 30% of the proton’s total measured spin. This unexpected finding left physicists wondering about the sources of the remaining spin.

Tesla to launch new Performance mode for Model 3 and Y

Tesla appears to be gearing up to launch a new Performance mode for the Model 3 and Model Y, as spotted in code from recent firmware updates.

On Sunday, Tesla code sleuth green the only posted about a “soft performance limit” option for the Model 3 and Y discovered in recent firmware, which the account says are listed as 110kW and 160kW, respectively. The discovery seems to suggest that Tesla is looking to launch a paid upgrade for the software-locked mode, allowing owners to upgrade to access full battery range.

Hm, interesting, recent firmwares bring “soft performance limit” option to Model3 and ModelY, listed as 110kW and 160kW respectively.

Iron Could Be Key to Cheaper, Greener Lithium-Ion Batteries

What if a common element rather than scarce, expensive ones was a key component in electric car batteries?

A collaboration co-led by an Oregon State University chemistry researcher is hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries.

The findings, published today in Science Advances, are important for multiple reasons, Oregon State’s Xiulei “David” Ji notes.
