Meta won’t have to face the next planned social media addiction trial
Less than a week before Meta's lawyers were set to return to a Los Angeles courtroom, the plaintiff accusing the platform of inflicting harm dropped the case. Brought by 15-year-old Florida plaintiff going by initials R.K.C., the case was set to be the second in a set of bellweth
Google justifies its massive AI spending with a booming cloud business
Google's cloud business is thriving, as companies adopting its AI and AI infrastructure services help the tech giant to report record profits.
Are penalties in the US airline industry a deterrent or a 'price?'
Many people drive more carefully for a while after receiving a traffic fine. But do large corporations, such as airlines, also change their behavior when they face financial penalties? We examine this question by studying penalties imposed in the United States for lengthy tarmac
New optical method follows single proteins as they shift shape
Researchers at the University of Twente have developed an optical method that follows the shape changes of a single protein in liquid without attaching anything to it. It reads the protein's structure from its own molecular vibrations, free from the labels or tags that other tech
Physics-based AI could boost biomedical imaging and autonomous vehicle sensors
A research team led by UCLA and the University of Rochester has demonstrated a promising evolution of an imaging system designed to capture details within "complex media," which scatter light, from depicting structures inside body tissue to seeing obstacles through heavy fog. The
Molecular model for semiconductor surfaces developed
Semiconductor surfaces can generally be studied only with considerable experimental effort, for example, in an ultrahigh vacuum. To more easily gain new insights into their properties and the possibilities for targeted modification, scientists at Heidelberg University have develo
More connections can deepen polarization when social ties remain weak
Social networks, intended to bring people together, can actually increase polarization, new research finds, because while the links in the network may be plentiful, they're probably weak. A research team including Cornell sociologist Michael Macy has found that while the growing
Chemists develop a molecular platform for the selective control of oxygen reaction pathway
Controlling how oxygen reacts is important for improving technologies such as batteries, fuel cells and environmentally sustainable chemical processes. A research team led by professor Seung Jun Hwang from KAIST's Department of Chemistry has developed a molecular system capable o
CRISPR-Cas coordinates a layered bacterial defense network in innate immunity
All cellular life—from humans to bacteria—possesses two layers of immunity: innate and adaptive. Scientists have long understood how these two types of immunity work together in higher organisms but not in the microbial world.
Q&A: Listening with light—an innovative new technology for studying the seafloor
The seafloor plays an important ecological and societal role. Understanding the processes that shape this environment will help guide conservation policy and decision-making about underwater infrastructure and geohazards.
First ever reported cryo-EM visualization of E. coli TGT structure
The enzyme tRNA-guanine transglycosylase (TGT) chemically modifies transfer RNA (tRNA) and plays a key role in how disease-causing bacteria control the production of proteins needed to cause infection. E. coli TGT is nearly identical to the one found in Shigella, which causes the
