Heavy workloads make employees feel a greater need for a break, but new research finds they may actually discourage employees from taking breaks at work despite causing high levels of stress, fatigue, and poor performance. Researchers from the University of Waterloo found employees often kept working despite wanting to pause. One potential reason is employees may have felt pressure to continue working to get everything done on time.  “Our research provides a comprehensive account of the processes involved in the decision to take a break and provides insights into how employees and managers can make more effective use of breaks at work, ...

Neurotrophin 3 (NT-3) is an important autocrine factor supporting ...

It’s easier than ever to view maps of any place you’d like to go — by car, that is. By foot is another matter. Most cities and towns in the U.S. do not have sidewalk maps, and pedestrians are usually left to fend for themselves: Can you walk from your hotel to the restaurants on the other side of the highway? Is there a shortcut from downtown to the sports arena? And how do you get to that bus stop, anyway?     Now MIT researchers, along with colleagues from multiple other universities, have developed an open-source tool that uses aerial imagery and image-recognition to create complete maps of sidewalks and crosswalks. The tool can help planners, policymakers, ...

Researchers of the HSE Graduate School of Business trained a machine-learning (ML) model to infer users' subjective wellbeing from social media posts. Having processed 10 million tweets, the researchers compiled a rating of holidays celebrated in Russia based on their popularity. The New Year tops the list, but Russian-speaking users of Twitter are also happy to celebrate Defender of the Fatherland Day, International Women's Day, Victory Day and Halloween. The study findings have been published in PeerJ Computer Science. As one of the most popular methods for ...

PHILADELPHIA – A new approach that delivers a “one-two punch” to help T cells attack solid tumors is the focus of a preclinical study by researchers from the Perelman School of Medicine at the University of Pennsylvania. The findings, published in the Proceedings of the National Academy of Sciences (PNAS), showed that targeting two regulators that control gene functions related to inflammation led to at least 10 times greater T cell expansion in models, resulting in increased antitumor immune activity and durability. CAR T cell therapy was pioneered at Penn Medicine by ...

A comprehensive analysis of an archaeological site in Saudi Arabia sheds new light on mustatils—stone monuments from the Late Neolithic period thought to have been used for ritual purposes. Melissa Kennedy of the University of Western Australia, Perth, and colleagues, in conjunction with The Royal Commission for AlUla present these findings in the open-access journal PLOS ONE on March 15, 2023. Built around 7,000 years ago, mustatils are rectangular, low-walled, stone structures that range from 20 to 600 meters in length. Researchers first discovered them in the 1970s, and more than 1,600 mustatils have now been discovered, primarily concentrated in northern ...

The sex hormone estrogen has a negative impact on heartbeat regulation, according to an experimental study from Linköping University, Sweden, published in Science Advances. Estrogen impact seems to interact with hereditary changes causing a heart disease disturbing the heart’s rhythm, while other endogenous substances may have a protecting effect. In a lifetime, the heart beats around 2.5 billion times. Each heartbeat is triggered by an electrical impulse that causes the heart muscle to contract in a very well-coordinated movement. ...

Researchers have identified evidence they interpret as active volcanism on the surface of Venus, according to a new analysis of radar images from the Magellan spacecraft. The images reveal a vent that changed shape on Venus, which they believe points to ongoing volcanic activity there. Many volcanoes have been identified on the surface of Venus, but evidence of recent volcanic activity on the planet has been lacking. As a result, it was unknown whether the prominent volcanic features of Venus’ geologically young surface are a product of ongoing active volcanism ...

Leesburg, VA, March 15, 2023—According to an accepted manuscript published in ARRS’ own American Journal of Roentgenology (AJR), sentiment of U.S. newspaper articles covering lung cancer screening (LCS) from 2010 to 2022 was overall positive; however, certain key elements of LCS were infrequently mentioned. “The findings highlight areas for potential improvement of LCS media coverage; radiologists have an opportunity to take a more active role in this coverage,” concluded first author Brent P. Little, MD, of Mayo Clinic Florida in Jacksonville. Little et al. searched the ProQuest U.S. Newsstream ...

Bumblebees are clumsy fliers. It is estimated that a foraging bee bumps into a flower about once per second, which damages its wings over time. Yet despite having many tiny rips or holes in their wings, bumblebees can still fly. Aerial robots, on the other hand, are not so resilient. Poke holes in the robot’s wing motors or chop off part of its propellor, and odds are pretty good it will be grounded. Inspired by the hardiness of bumblebees, MIT researchers have developed repair techniques that enable a bug-sized aerial robot to sustain severe damage to the actuators, or artificial muscles, that power its wings — but to still fly effectively. They optimized these artificial muscles ...

Resilience and well-being in difficult times can be developed via online interventions in the workplace. An international team of researchers from France, the UK and Russia (with the participation of researchers from the HSE International Laboratory of Positive Psychology of Personality and Motivation) studied the effectiveness of SPARK Resilience, a programme for developing resilience, at the beginning of the COVID-19 pandemic.

Embargoed: Not for release until 2 p.m. U.S. Eastern time Wednesday, March 15, 2023 Venus appears to have volcanic activity, according to a new research paper that offers strong evidence to answer the lingering question about whether Earth’s sister planet currently has eruptions and lava flows. Venus, although similar to Earth in size and mass, differs markedly in that it does not have plate tectonics. The boundaries of Earth’s moving surface plates are the primary locations of  volcanic activity. New research by University of Alaska Fairbanks Geophysical Institute research professor Robert Herrick revealed ...

The long-term effects on forests of more extreme climate events, plus other drivers of forest change, are highly uncertain. A new study of the tropical forests across Puerto Rico and the U.S. Virgin Islands (USVI), spanning 19 years, found that after Hurricane Maria in 2017, the total biomass of a fast-growing nonnative species, the African tulip Tree (Spathodea campanulata), may again be overtaking that of the most common group of native tree species, even though, at least for young and small trees, nonnatives ...

For some people receiving methadone for treatment of opioid use disorder (OUD), the co-use of opioids and stimulants such as cocaine is an issue. Now, a new study led by Johns Hopkins Medicine researchers found that bupropion, an antidepressant medication also used for smoking cessation, may help people stop using cocaine while in treatment for OUD. The results of the study were published March 15 in JAMA Network Open. For this double-blind randomized study, the researchers used an adaptive treatment design, meaning that it allowed ...
