Method for solving notorious calculus problems speeds particle physics computations

For decades, theoretical particle physicists have struggled with vexing calculus problems called Feynman integrals. They are central to every calculation they make—from predicting how magnetic a particle called the muon should be , to estimating the rate at which Higgs bosons should emerge at the Large Hadron Collider (LHC). Now, theorists have found a way...

Finding the answers hidden in our antibodies

An innovative protocol called PepSeq is changing the way researchers test for contagious diseases -- and this knowledge should change the way humanity responds to future pandemics. Researchers just published a comprehensive study about PepSeq that lays out the process, the tool and how to interpret the results, with the goal of more, better and faster information for the next outbreak.

Simulated driving program reduces crash risk for teens with ADHD in small study

A program that combines computer-based and driving simulator training may reduce the proportion of crashes and near crashes among teens with attention-deficit/hyperactivity disorder (ADHD), according to a small study. Teens who took the training, which aims to reduce the number of long glances away from the roadway, had a nearly 40% lower risk for crash or near crash, compared to a similar group...

Fear of professional backlash may keep women from speaking up at academic conferences

Academic conferences provide invaluable opportunities for researchers to present their work and receive feedback from attendees during question-and-answer sessions. Women are less likely to ask questions during these sessions, however, and research in Psychological Science suggests that this may be due to anxiety about how colleagues will receive their comments.

Stanford investigates potential misconduct in president’s research

Stanford University has launched an investigation of possible research misconduct in several papers co-authored many years ago by its president, neuroscientist Marc Tessier-Lavigne, after the school’s student newspaper raised questions about potentially manipulated images in the articles, published long before he came to the school. The university “will assess...

Researchers demonstrate light-induced locomotion in a nonliquid environment and report a new type of liquid-like motion

Motion is everywhere in living systems and is necessary for mechanical functions in artificial systems, such as robots and machines. Functional mechanical structures that can change volume and shape in response to external stimuli (such as light, heat, electricity, humidity, and chemistry) have a wide range of application prospects in the field of biomechanics and bionic robots. They have...

Researchers build powerful model for discovering new drugs

Researchers have developed a new computer framework that holds promise in the work to discover new drugs. Their framework uses an artificial intelligence method called a convolutional neural network to provide global information about potential novel drug candidates.

Steep fall in implementation of physical activity policy in Ontario schools

Children have become less physically active in school, despite teachers recognizing the importance of daily movement. Now, a new study published in BMC Public Health reveals the implementation of Ontario's Daily Physical Activity (DPA) policy is in sharp decline. The reasons, according to the study, include time constraints and low confidence among teachers about their ability to implement the...

Concussion and head trauma in contact sports to be examined by parliamentary inquiry, Greens say

Individuals' cognitive transformations key to understanding desistance from crime, argues expert

Much of U.S. criminal justice policy focuses on recidivism, and probation and parole violators make up a considerable share of jail and prison populations. In a new article, a 2022 winner of the Stockholm Prize in Criminology argues that to understand desistance—the process of reducing or ending criminal behavior—we must consider the role of individuals' cognitive transformations.

Physicists produce symmetry-protected Majorana edge modes on quantum computer

Physicists at Google Quantum AI have used their quantum computer to study a type of effective particle that is more resilient to environmental disturbances that can degrade quantum calculations. These effective particles, known as Majorana edge modes, form as a result of a collective excitation of multiple individual particles, like ocean waves form from the collective motions of water molecules....

Machine-learning model instantly predicts polymer properties

Hundreds of millions of tons of polymer materials are produced globally for use in a vast and ever-growing application space with new material demands such as green chemistry polymers, consumer packaging, adhesives, automotive components, fabrics and solar cells.

Male orb-weaving spiders fight less in female-dominated colonies

Orb-weaving spiders cooperate for more peaceful colonies, a surprising revelation given that most spiders live solitarily. In the colonies that researchers observed, male spiders fought less with one another when there were more female spiders in a colony. But colonies with large numbers of larger and medium-sized female spiders tended to have more aggressive environments.
