Published in Nature Catalysis, the six chemists discovered a method that could be used to produce other chemicals.

A group of authors led by Pulitzer Prize winner Michael Chabon has filed suit against Meta and OpenAI in federal court in San Francisco. Another, you might rightfully ask.

The allegations are the same as in the pending lawsuits: direct and vicarious copyright infringement, removal of copyright information, unfair competition, and negligence.

The authors allege that their copyrighted works have been included in the training material of the respective AI systems without authorization, specifically in the so-called book datasets.

Researchers have confirmed that human brains are naturally wired to perform advanced calculations, similar to e a high-powered computer, to make sense of the world through a process known as Bayesian inference.

In a recent study published in Nature Communications.

<em>Nature Communications</em> is a peer-reviewed, open-access, multidisciplinary, scientific journal published by Nature Portfolio. It covers the natural sciences, including physics, biology, chemistry, medicine, and earth sciences. It began publishing in 2010 and has editorial offices in London, Berlin, New York City, and Shanghai.

Any physical object, alive or inanimate, is composed of atoms and subatomic particles that interact in different ways governed by the principles of quantum mechanics. Some particles are in a pure state—they remain fixed and unchanged. Others are in a quantum state—a concept that can be difficult to understand because it involves having a particle occupy multiple states simultaneously. For instance, an electron in a pure state spins up or down; in a quantum state, also referred to as superposition, it spins up and down simultaneously. Another quantum principle states that particles can be in a state of entanglement in which changes in one directly affect the other. The principles of superposition and entanglement are fundamental to quantum computing.

Quantum bits, or qubits, are the smallest units of data that a quantum computer can process and store. In a pure state, qubits have a value of 1 or 0, similar to the bits used in computing today. In superposition, they can be both of these values simultaneously, and that enables parallel computations on a massive scale. While classical computers must conduct a new calculation any time a variable changes, quantum computers can explore a problem with many possible variables simultaneously.

Existing computers, although sufficient for many applications, can’t fully support all of the changes required to create a connected and intelligent-mobility ecosystem. Quantum computing (QC) could potentially provide faster and better solutions by leveraging the principles of quantum mechanics—the rules that govern how atoms and subatomic particles act and interact. (See sidebar, “Principles of quantum computing,” for more information). Over the short term, QC may be most applicable to solving complex problems involving small data sets; as its performance improves, QC will be applied to extremely large datasets.

“Lightning” system connects photons to the electronic components of computers using a novel abstraction, creating the first photonic computing prototype to serve real-time machine-learning inference requests.

Computing is at an inflection point. Moore’s Law, which predicts that the number of transistors on an electronic chip will double each year, is slowing down due to the physical limits of fitting more transistors on affordable microchips. These increases in computer power are slowing down as the demand grows for high-performance computers that can support increasingly complex artificial intelligence models. This inconvenience has led engineers to explore new methods for expanding the computational capabilities of their machines, but a solution remains unclear.

A new episode of our podcast, “Show Me the Science,” has been posted. These episodes feature stories about groundbreaking research, as well as lifesaving and just plain cool stuff involving faculty, staff and students at Washington University School of Medicine in St. Louis.

In this episode, Washington University researchers discuss the Food and Drug Administration’s recent full approval of the drug Leqembi (lecanemab) and what it could mean to the future of Alzheimer’s disease treatments. The drug is approved for use in people with mild dementia from Alzheimer’s disease, but researchers at Washington University’s Charles F. and Joanne Knight Alzheimer Disease Research Center (ADRC), believe the drug, along with other medications in clinical trials, one day may help prevent the development of memory loss and problems with thinking in people who have Alzheimer’s pathology in the brain but who have not yet developed clinical symptoms of the disease.

Barbara Joy Snider, MD, PhD, a professor of neurology and director of clinical trials at the Knight ADRC, says that although Leqembi doesn’t cure Alzheimer’s disease, it slows the decline in memory and thinking, and it also slows the progression of the disorder by removing some amyloid plaques from the brain.

Even when a bone marrow transplant cures leukemia or lymphoma, GVHD—in which T cells in the donor graft attack the recipient’s own tissues—can still be fatal. The condition is among the leading causes of death and long-term adverse health consequences associated with bone marrow transplants.

Senior co-corresponding authors Ivan Maillard, MD, PhD, a professor of Medicine and vice chief for research in Hematology-Oncology at the Perelman School of Medicine at the University of Pennsylvania, and Leslie S. Kean, MD, PhD, a professor of Pediatrics at Harvard Medical School and director of Pediatric Stem Cell Transplant at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, along with… More.

In new preclinical research, an experimental antibody treatment largely prevented a bone marrow transplant complication called graft versus host disease in the intestines, without causing broad immune suppression, paving the way for clinical trials.

Digesting a crunchy critter starts with the audible grinding of its rigid protective covering — the exoskeleton. Unpalatable as it may sound, the hard cover might be good for the metabolism, according to a new study, in mice, from Washington University School of Medicine in St. Louis. The researchers, led by Steven Van Dyken, PhD, an assistant professor of pathology & immunology, found in mice that digesting chitin, an abundant dietary fiber in insect exoskeletons and also mushrooms and crustacean shells, engages the immune system. An active immune response was linked to less weight gain, reduced body fat and a resistance to obesity. “Obesity is an epidemic,” Van Dyken said. “What we put into our bodies has a profound effect on our physiology and on how we metabolize food. We’re investigating ways to counteract obesity based on what we learn about how the immune system is engaged by diet.”

Findings, in mice, suggest engaging immune system with such fiber to counteract obesity.
