Finish the Fight

Image: Sony Ahead of the PS5 Pro launch later this week, we have confirmation of a few more official specifications for the most powerful version of the PS5 yet. Digital Foundry has shared details from the manual included with its PS5 Pro review unit, confirming the console is powered by an AMD Ryzen Zen 2 8-core/16-thread processor with an RDNA-based graphics engine producing 16.7TF of GPU compute performance compared to the base PS5’s 10.23TF. As we noted in March, initial leaked documents showed a much higher figure for the PS5 Pro, mostly due to a change in AMD’s RDNA architecture. The manual also reveals that in addition to 16GB of GDDR6 memory, the PS5 Pro will have 2GB of slower DDR5 memory for handling console tasks not related to gaming,... Continue reading…

Using simple circuitry, polarizing film, and LEGO toy bricks, an undergraduate physics student from the Ateneo de Manila University built an improvised polarimeter that can optically assess the purity of Vitamin C (ascorbic acid) and other chiral substances.

When torrential rains and powerful winds hit densely populated coastal regions, whole cities can be destroyed—but governments and residents can take precautions with sufficient warning.

The AI tool AlphaFold has been improved so that it can now predict the shape of very large and complex protein structures. Linköping University researchers have also succeeded in integrating experimental data into the tool. The results, published in Nature Communications, are a step toward more efficient development of new proteins for, among other things, medical drugs.

A team of researchers have discovered a metal-organic framework (MOF) that suppresses charge recombination, which is a major challenge in photocatalytic overall water splitting. Their study was published in Nature Chemistry.

A German-American research team has discovered two highly unusual bacterial species in the tissue of two deep-sea corals from the Gulf of Mexico. These previously unknown coral symbionts have an extremely reduced genome and lack the ability to obtain energy from carbohydrates, the team reports in an article published in the journal Nature Communications.

As the Earth faces unprecedented climate change, a look into the planet's deep past may provide vital insights into what may lie ahead. Knowledge of the natural world millions of years ago is fragmented, but a 15-year study of a site in Bolivia by an international team led by Case Western Reserve University provides a comprehensive view of an ancient ecosystem when the Earth was much warmer than today.

Fifteen minutes before the massive January 2022 eruption of the Hunga Tonga-Hunga Ha'apai volcano, a seismic wave was recorded by two distant seismic stations. Now, researchers argue that similar early signals could be used to warn of other impending eruptions in remote oceanic volcanoes.

Fine tuning an experimental setup improved a detector's sensitivity to neutrinos and perhaps eventually dark matter—two difficult-to-measure forms of matter which hold great importance for understanding particle physics and experimental cosmology. The University-of-Michigan-led study is published in Physical Review D.
