Leaders' pandemic policies engendered varying levels of trust

In a new study, Molly Crockett, an associate professor of psychology at Yale, examined whether people trust leaders who make utilitarian decisions during a pandemic. To find out, she and her co-first authors -- Yale's Clara Colombatto and the University of Kent's Jim Everett -- assembled a multidisciplinary team of 37 international researchers to study people's trust in leaders around the globe.

Manufacturing the core engine of cell division

Mitosis, the mechanism of cell division that is so important for life, involves more than 100 proteins at its core. The group of Professor Andrea Musacchio from the Max Planck Institute of Molecular Physiology in Dortmund has been able to fully reconstitute the engine of the mitosis machinery, called kinetochore. This is the first step towards the making of artificial chromosomes, that may one day...

Mefloquine: A promising drug 'soldier' in the battle against COVID-19

In the 'war' that the world has been fighting against COVID-19, scientists have been scanning their arsenals of previously used drugs in hopes of finding any that can be used to treat the disease. One of the contenders under scrutiny, an anti-malarial drug called mefloquine shows great promise, according to a new breakthrough study by a team of Japanese scientists, perhaps giving us a better...

Near-death experiences, a survival strategy ?

A new study conducted jointly by the University of Copenhagen (Denmark) and the University of Liege (Belgium) and published in Brain Communications shows how near-death experiences in humans may have arisen from evolutionary mechanisms. Researchers attribute for the first time a biological purpose to NDEs.

New algorithms give digital images more realistic color

In Optica, The Optical Society's (OSA) journal for high impact research, researchers describe a new approach for digitizing color. It can be applied to cameras and displays -- including ones used for computers, televisions and mobile devices -- and used to fine-tune the color of LED lighting.

New approach can add diversity to crop species without breeding GMOs

Breeding better crops through genetic engineering has been possible for decades, but the use of genetically modified plants has been limited by technical challenges and anti-GMO misinformation. A new approach potentially solves both of those problems by modifying the energy-producing parts of plant cells and then removing the DNA editing tool so it cannot be inherited by future seeds.

New GSA Bulletin articles published ahead of print in June

The Geological Society of America regularly publishes articles online ahead of print. GSA Bulletin topics include multiple articles about the dynamics of China and Tibet; the end-Permian terrestrial extinction paradigm in South Africa; prehistoric lava flows from the urban district of Catania (Etna volcano, Italy); the debated origins of granite, and "a tale of two Tweefonteins."

New study shows glo has similar impact on indicators of potential harm as quitting smoking

New research published today in the journal Internal and Emergency Medicine provides the first real-world evidence that people switching from cigarettes to exclusive use of glo, BAT's flagship Tobacco Heating Product (THP), can significantly reduce their exposure to certain toxicants and indicators of potential harm related to several smoking-related diseases compared with continuing to smoke.

Newly discovered genetic variants in a single gene cause neurodevelopmental disorder

Mayo Clinic researchers have discovered that genetic variants in a neuro-associated gene called SPTBN1 are responsible for causing a neurodevelopmental disorder. The study, published in Nature Genetics, is a first step in finding a potential therapeutic strategy for this disorder, and it increases the number of genes known to be associated with conditions that affect how the brain functions.

Older patients with heart failure denied effective treatments

Heart failure patients aged 80 and above are less likely to receive recommended therapies and dosages compared to their younger counterparts, according to research presented today at Heart Failure 2021, an online scientific congress of the European Society of Cardiology (ESC). 'Guidelines recommend the same treatments for all heart failure patients regardless of age,' said study author Dr. Davide...

Patients paying for unproven IVF add-on treatments

Despite only limited evidence that fertility add-ons increase the odds of having a baby, the majority of women (82%) have used one or more of these treatments as part of their IVF.This is the conclusion of a retrospective study of 1,590 Australian patients which also found more than seven in 10 (72%) had incurred additional costs for these unproven additional therapies and techniques which range...

Plastic drapes reduce hypothermia in premature babies

A University of Houston College of Nursing researcher is reporting that use of a plastic drape during catheter insertion in very low birth-weight newborn babies can lower the rates of hypothermia, and she is recommending replacing cloth blanket and towels with them.

Recent technology cost forecasts underestimate the pace of technological change

A comparison of observed global energy technology costs, with forecasts generated by models and forecasts predicted by human experts, showed that both forecasting methods underestimated cost reductions. This suggests that decisions based on forecasts may be overestimating the cost of climate mitigation and points to the need to further improve forecasting methods.
