A new approach to analysing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, causing space weather events. The first direct evidence that field lines become knotted before they emerge at the visible surface of the Sun has implications for our ability to predict the behaviour of active regions and the nature of the solar interior.

Two years on from its pledge to make England smoke free by 2030, the UK government has failed to deliver on the policies it promised to deliver this ambition, say a group of leading doctors, professional bodies and charities in The BMJ today.

Remote 24-hour monitoring for cancer patients receiving chemotherapy helps to better manage side effects and improve quality of life, finds a study published by The BMJ today.

Results from a new RAS survey of astronomers and geophysicists show that these sciences have a systemic bullying problem; one that is disproportionately worse for women and those from minority groups. Aine O'Brien, RAS Diversity Officer, will present the key results in a talk at the virtual National Astronomy Meeting on Thursday 22 July.

Pregnant women in South East Asia are more likely to use smokeless tobacco than non-pregnant women, despite the added risk of foetal harm during pregnancy.

Not enough progress has been made to address physical inactivity worldwide, with adolescents and people living with disabilities (PLWD) among the least likely populations to have the support needed to meet the World Health Organization (WHO)'s physical activity guidelines. Global efforts to improve physical activity have stalled, with overall deaths caused by physical activity remaining at more than 5 million people per year.

The International Association for Dental Research (IADR) announced David Williams, Barts and The London School of Medicine and Dentistry, Queen Mary University of London, UK, as the 2021 recipient of the IADR Gold Medal Award. Williams was recognized during the Opening Ceremonies of the virtual 99th General Session & Exhibition of the IADR held on July 21-24, 2021.

Two recently published studies indicate Epstein-Barr virus (EBV) reactivation may play a role both in the development of long COVID symptoms, as well as severe COVID-19 cases. A study in Pathogens found over 73% of COVID-19 patients who were experiencing long Covid symptoms were also positive for EBV reactivation. A study in Scientific Reports by Nature found EBV reactivation was also associated with COVID-19 severity.

In the wild, inheriting advantageous physical traits may be the difference between a long life and a short one. But for the spotted hyena, another kind of inheritance, one that has nothing to do with genetics, turns out to be extremely important for health and longevity -- social networks inherited from their mothers.

A new paper published in the New England Journal of Medicine outlines a clinical trial, conducted in 392 people with psychosis associated with Alzheimer's disease, Parkinson's disease, Lewy body, frontotemporal, or vascular dementia. All participants were given pimavanserin for 12 weeks. Those who met a threshold of symptom improvement were then assigned to pimavanserin or placebo for up to 26 weeks.

The Feinberg group's latest model mimics physiologic loads on engineering heart muscle tissues, yielding an unprecedented view of how genetics and mechanical forces contribute to heart muscle function.

Researchers at the NYU Center for Cyber Security at the NYU Tandon School of Engineering are rethinking basic functions that drive the ability of neural networks to make inferences on encrypted data.

A collaboration across three continents at the frontiers of physics, biology, and engineering co-led by Maurizio Porfiri at NYU Tandon, applied super computing muscle and special software to a novel simulation of the Venus' flower basket sponge.

In a recently published paper, a research team, led by University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science Professor Emeritus Joseph M. Prospero, chronicles the history of African dust transport, including three independent "first" discoveries of African dust in the Caribbean Basin in the 1950s and 1960s.

The method from a research team led by Professor Horacio Espinosa could lead to more accurate predictions of how new materials behave at the atomic scale.

A team of scientists at Los Alamos National Laboratory propose that modulated quantum metasurfaces can control all properties of photonic qubits, a breakthrough that could impact the fields of quantum information, communications, sensing and imaging, as well as energy and momentum harvesting.

Researchers from the University of Southern California and NVIDIA have unveiled a new simulator for robotic cutting that can accurately reproduce the forces acting on a knife as it slices through common foodstuffs, such as fruit and vegetables. The system could also simulate cutting through human tissue, offering potential applications in surgical robotics. The paper was presented at the Robotics: Science and Systems (RSS) Conference 2021 on July 16.

In a new study, researchers have uncovered how cytolysins from Enterococcus faecalis destroys bacterial and mammalian cells.

Alexandria, Va., USA - Walter Siqueira, University of Saskatchewan, Saskatoon, Canada, presented the poster "Self-collected Saliva and Courier Service - A Feasible Diagnostic Strategy for COVID-19" at the virtual 99th General Session & Exhibition of the International Association for Dental Research (IADR), held in conjunction with the 50th Annual Meeting of the American Association for Dental Research (AADR) and the 45th Annual Meeting of the Canadian Association for Dental Research (CADR), on July 21-24, 2021.

Exoskeletons - wearable devices used by workers on assembly lines or in warehouses to alleviate stress on their lower backs - may compete with valuable resources in the brain while people work, canceling out the physical benefits of wearing them, a new study suggests.
