Pigs show potential for 'remarkable' level of behavioral, mental flexibility in new study

Peer reviewed / Review and opinion First comprehensive assessment of damage to health inflicted by former President Trump cites decades of policy failures made worse by the Trump administration, resulting in 461,000 unnecessary US deaths annually before the COVID-19 pandemic, and tens of thousands of unnecessary COVID-19 and pollution-related deaths attributable to his actions. Lancet Commission calls for immediate rollback of Trump's health-harming policies and additional sweeping reforms to reverse the deteriorating health of the US population: "The path away from Trump's politics of anger and despair cannot lead through past policies." The first comprehensive assessment of the health effects of Donald Trump's presidency is published today ...

Researchers at Linköping University, Sweden, have developed biosensors that make it possible to monitor sugar levels in real time deep in the plant tissues - something that has previously been impossible. The information from the sensors may help agriculture to adapt production as the world faces climate change. The results have been published in the scientific journal iScience. The primary source of nutrition for most of the Earth's population is mainly plants, which are also the foundation of the complete ecosystem on which we all depend. Global population ...

A tiny population of neurons known to be important to appetite appear to also have a significant role in depression that results from unpredictable, chronic stress, scientists say. These AgRP neurons reside exclusively in the bottom portion of the hypothalamus called the arcuate nucleus, or ARC, and are known to be important to energy homeostasis in the body as well prompting us to pick up a fork when we are hungry and see food. Now Medical College of Georgia scientists and their colleagues report the first evidence that, not short-term stress, like a series of tough college exams, rather chronic, unpredictable stress like that which erupts in our personal and professional lives, induces changes in the function of AgRP neurons that may contribute to depression, they ...

Researchers from University of Amsterdam and Stanford University published a new paper in the Journal of Marketing that examines explores how human-as-machine representations affect consumers--specifically their eating behavior and health. The study, forthcoming in the Journal of Marketing, is titled "Portraying Humans as Machines to Promote Health: Unintended Risks, Mechanisms, and Solutions" and is authored by Andrea Weihrauch and Szu-Chi Huang. To combat obesity, governments, marketers, and consumer welfare organizations often encourage consumers ...

Obesity and excess body fat may have contributed to more deaths in England and Scotland than smoking since 2014, according to research published in the open access journal BMC Public Health. Between 2003 and 2017 the percentage of deaths attributable to smoking are calculated to have decreased from 23.1% to 19.4% while deaths attributable to obesity and excess body fat are calculated to have increased from 17.9% to 23.1%. The authors estimate that deaths attributable to obesity and excess body fat overtook those attributable to smoking in 2014. Jill Pell, at the University of Glasgow, United Kingdom, the corresponding author said: "For several decades smoking has been a major target of public ...

The needs of millions of overlooked, 'left behind' adolescent women must become a more significant priority within international efforts to end poverty by 2030, a UK Government-commissioned report is urging. The University of Cambridge report, which was commissioned by the Foreign, Commonwealth and Development Office, argues that there is an urgent need to do more to support marginalised, adolescent women in low and middle-income countries; many of whom leave education early and then face an ongoing struggle to build secure livelihoods. Amid extensive evidence which highlights the difficulties these women face, it estimates that almost a third of adolescent ...

One third (35%) of people who took a new drug for treating obesity lost more than one-fifth (greater than or equal to 20%) of their total body weight, according to a major global study involving UCL researchers. The findings from the large-scale international trial, published today in the New England Journal for Medicine, are being hailed as a "gamechanger" for improving the health of people with obesity and could play a major part in helping the UK to reduce the impact of diseases, such as COVID-19. The drug, semaglutide, works by hijacking the body's own appetite regulating system in the brain leading to reduced hunger and calorie intake. Rachel Batterham, Professor of Obesity, Diabetes and Endocrinology ...

MUSC Hollings Cancer Center researchers found that a single strain of bacteria may be able to reduce the severity of graft-versus-host disease (GVHD), as reported online in February 2021 in JCI Insight. Bone marrow transplant can be a lifesaving procedure for patients with blood cancers. However, GVHD is a potentially fatal side effect of transplantation, and it has limited treatment options. This proof-of-concept study demonstrates that better treatment options may be on the horizon for patients with GVHD. Xue-Zhong Yu, M.D., associate director of Basic Science at Hollings Cancer Center, and lead ...

Researchers at the University of Maryland School of Medicine (UMSOM) and their colleagues published a new analysis today in the journal Nature from genetic sequencing data of more than 53,000 individuals, primarily from minority populations. The early analysis, part of a large-scale program funded by the National Heart, Lung, and Blood Institute, examines one of the largest and most diverse data sets of high-quality whole genome sequencing, which makes up a person's DNA. It provides new genetic insights into heart, lung, blood and sleep disorders and how these conditions impact people with diverse racial and ...

A team, including an astronomer from the University of Hawai?i Institute for Astronomy (IfA), have confirmed a planetoid that is almost four times farther from the Sun than Pluto, making it the most distant object ever observed in our solar system. The planetoid, nicknamed "Farfarout," was first detected in 2018, and the team has now collected enough observations to pin down the orbit. The Minor Planet Center has now given it the official designation of 2018 AG37. Farfarout's name distinguished it from the previous record holder "Farout," found by the same team of astronomers in 2018. The team includes UH Mānoa's David Tholen, Scott S. Sheppard of ...
