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.
Low-income patients may be less likely to receive medical assistance in dying
In Canada, low-income hospital patients under palliative care are less likely to receive medical assistance in dying compared to those who are high income.
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...
Massive exome-wide association study in humans identifies rare variants that protect against obesity
Through the sequencing of more than 640,000 human exomes, researchers identify rare gene coding variants strongly associated with body mass index (BMI) - including the variant GPR75, which conferred protection from obesity in mouse models.
Mayo Clinic study suggests patients with lung cancer be screened for MET oncogene
Research by investigators at Mayo Clinic Cancer Center suggests that physicians should screen patients with lung cancer for MET amplification/overexpression before determining a treatment strategy.

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...
Moderna and Pfizer-BioNTech vaccines prime T cells to fight SARS-CoV-2 variants
Researchers at La Jolla Institute for Immunology (LJI) have found that T cells from people who have recovered from COVID-19 or received the Moderna or Pfizer-BioNTech vaccines are still able to recognize several concerning SARS-CoV-2 variants.
Multimodality care improves treatment outcomes for aggressive prostate cancer
Men with high-risk prostate cancer with at least one additional aggressive feature have the best outcomes when treated with multiple healthcare disciplines, known as multimodality care, according to a UCLA study.
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 chatbot can explain apps and show you how they access hardware or data
Researchers at Aalto University have harnessed the power of chatbots to help designers and developers develop new apps and allow end users to find information on the apps on their devices. The chatbot 'Hey GUI' can answer questions by showing images and screenshots of apps, or through simple text phrases.
New data science platform speeds up Python queries
Data queries written in Python, a commonly used programming language, can grind data analytics platforms to a crawl, but a new platform developed by researchers from Brown and MIT may finally solve the Python efficiency problem.

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 research should prioritize vaccination strategies for organ transplant recipients
In a new Editorial, Peter Heeger, Christian Larsen, and Dorry Segev discuss recent evidence - including a recent Science Immunology study by Hector Rincon-Arevalo and colleagues - that points to a diminished immune response to COVID-19 vaccines among organ transplant recipients and others on immunosuppressive drug regimens.
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.
New technology detects greater variety of T cells that respond to coronaviruses
Scientists have developed a new technology to detect a wider variety of T cells that recognize coronaviruses, including SARS-CoV-2.
New ternary hydrides of lanthanum and yttrium join the ranks of high-temperature superconductors
Welcome a new member in the family of superconducting polyhydrides: A team led by Skoltech professor Artem R. Oganov studied the structure and properties of ternary hydrides of lanthanum and yttrium and showed that alloying is an effective strategy for stabilizing otherwise unstable phases YH10 and LaH6, expected to be high-temperature superconductors.
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.
