Nvidia’s stock slid more than 4% after its board opened an investigation into Jensen Huang’s relationship with a suspected Chinese spy, and one securities law expert says the company’s earlier insistence that it was all “normal” could turn into a very expensive problem.

An infrared signal thought to reveal how molecules in perovskite solar materials respond to light-generated charges can arise largely from the way light travels through the thin film itself, a new theoretical study shows. Jun Nishida, assistant professor at the Institute for Molecular Science (IMS), Japan, found that light-generated charges alter how infrared light is reflected and transmitted within the film layers, producing sharp features that resemble changes in molecular vibrations even when the vibrations themselves are unaltered.

Helicenes are a class of organic molecules consisting of benzene rings arranged in a spiral-like shape. These molecules exhibit significant circularly polarized luminescence—emission of light with left or right handedness—and are expected to be utilized in 3D displays and anti-counterfeiting inks. Carbohelicenes, a subgroup of helicenes, are composed entirely of carbon and hydrogen.

Today’s cataclysmic climate change-fueled disasters are scary enough even when we understand the root causes. Prehistoric cultures unfortunately didn’t have this luxury, and often responded dramatically to such changes. In northern Peru, archaeological evidence indicates local societies sometimes even turned to mass human sacrifices in an attempt to stop destructive flooding from events like El Niño. That said, researchers are now confident these periods of intense violence weren’t the norm—nor were they necessarily linked to climate issues. According to their study recently published in Frontiers in Environmental Archaeology, such brutal moments were actually pretty rare occurrences in Peru’s Lambayeque Valley.…

A week after a humiliating midterms, Elon Musk is back to his old habits: flirting with Nazism. Perhaps Musk really didn’t intend to perform back-to-back salutes that suspiciously looked a lot like a Sieg Hiel at a Trump inauguration party nearly two years ago, but you have to admit that he has quite the track record when it comes to espousing white supremacist conspiracy theories and interacting with people who wouldn’t hesitate to describe themselves as outright Nazis. This time, his racist run-in was even called out by his own chatbot, Grok. On Sunday night, Musk responded to a supremacist…
