Nearly one in three Americans wear a wearable device, like a smartwatch, to track their health and fitness. Studies have shown positive effects of increasing movement in ways that can be measured by these devices, especially for people who recently had a heart attack or other cardiovascular event. But a Michigan Medicine-led report shows that adding a mobile health application to such devices yields mixed results. Tailored text messages to encourage high-risk people to move more may improve some short-term outcomes but doesn’t always improve physical activity levels for everyone.   The ...

A study digs into a topical debate: should institutions accept donations from bad people? Jeffrey Epstein donated to MIT after he was a convicted sex offender. The Sackler family donated to museums around the world, which had to decide whether to keep their names on display and whether to continue accepting funds after the family faced widespread criticism and legal consequences for pushing addictive painkillers on the public. Ethicists are often split on whether organizations should take money from morally tainted donors. The money can support good outcomes in the world, but the reputation of the organization may suffer and the public ...

Previous studies have shown that yoga therapy and lifestyle modifications have improved heart failure patients’ quality of life and enhanced their cardiovascular function. A new study, presented at the American College of Cardiology Asia 2023 conference, examines the long-term outcomes of yoga therapy to determine the benefit of adding yoga therapy as a complementary treatment in the management of heart failure. Heart failure is a form of cardiovascular disease where the heart muscle is either too weak or too stiff to pump properly, often leading to fluid buildup, shortness of breath and other complications. ...

Over the past few years, the field of artificial intelligence (AI) has witnessed numerous breakthroughs. One such remarkable milestone was the development and adoption of chatbots and conversational agents based on large language models, including ChatGPT. These systems can engage in realistic, human-like conversations with users and help them in many ways, such as by curating information, generating recommendations, or assisting in complex tasks. Interestingly, owing to their pre-training on large amounts of data, chatbots like ChatGPT are capable of generating highly personalized recommendations, considering factors like user’s interests, ...

Hospital visits from alcohol- and substance-related disorders are driven by elevated temperatures and could be further affected by rising temperatures due to climate change, according to new research by environmental health scientists at Columbia University Mailman School of Public Health.  The study, which is published in the peer-reviewed journal Communications Medicine, is likely the first comprehensive investigation of the association between temperature and alcohol- and substance-related hospital visits.   “We ...

LA JOLLA (September 26, 2023)—Movement offers a window into how the brain operates and controls the body. From clipboard-and-pen observation to modern artificial intelligence-based techniques, tracking human and animal movement has come a long way. Current cutting-edge methods utilize artificial intelligence to automatically track parts of the body as they move. However, training these models is still time-intensive and limited by the need for researchers to manually mark each body part hundreds to thousands of times. Now, Associate Professor Eiman Azim and team have created GlowTrack, a non-invasive movement tracking method that uses fluorescent dye markers to train ...

Key points   Biosensing has been valuable for detecting biomolecules, including novel coronavirus (SARS-CoV-2), but achieving both high sensitivity and rapidity has been challenging.   Rapid and high-sensitivity detection of SARS-CoV-2 was achieved by utilizing optical-to-electric frequency conversion of optical combs and active-dummy temperature compensation with dual-optical-comb configuration.   This enables ultra-early detection of infectious pathogens, health biomarkers, food contaminants, environmental hormones, and more, contributing to various preventive measures. Research Introduction ...

Indigenous communities act in sophisticated ways to deter unauthorised mining in Colombia, shows a recently published book by Postdoctoral Researcher Diana Arbeláez-Ruiz from the University of Eastern Finland. The book focuses on Indigenous people and mining in Colombia’s North Cauca region, where multiple armed groups and illicit economies operate. The research the book is based upon was carried out in 2016–2019. As the illegal armed group presence and illicit economies situation in the region has intensified since, the book remains highly topical today. Published by Routledge, the book documents what the Nasa Indigenous community do to stop unauthorised mining in their ...

*Embargoed until 07:00 BST / 08:00 CEST, 26 September 2023* The grounding line of the southern Ronne Ice Shelf in Antarctica can shift up to 15 km (six miles) with changing tides, new analysis shows. The research, published today in The Cryosphere, examines the key region where land-based Antarctic ice spills over into the surrounding ocean. Observing and understanding the dynamics of this region can help scientists predict Antarctica’s response to climate change, and so how much global sea levels will rise. “We typically think of ice sheet change as being very slow, ...

The illegal wildlife trade (IWT) is a fast-growing ‘financial portfolio’ within the larger illegal, violent, parallel transnational global economy. As such, it creates state-level security and development risks, especially in source countries. IWT is also known as wildlife trafficking, which includes the illicit trade of animals and plants, and derivative products such as pangolin scales, rhino horn, elephant ivory, lion and tiger bones, and leopard pelts. But many highly developed countries signed up to CITES, are yet to implement a crucial legal instrument required to prosecute IWT and the associated financial ...

Imagine you’re sitting in your living room on a quiet evening with your family reading a book, when suddenly, complete strangers let themselves in your front door. If that wasn’t enough of a shock, before you can even find your voice to ask who they are, they begin rearranging your furniture, painting your walls different colors, bagging up possessions that are important to you, and appear to be swapping out the food in your refrigerator. They do not seem to mean you any harm and work with such purpose that you question yourself, wondering whether you may have forgotten ...

WASHINGTON – A new paper by Environmental Working Group scientists proposes an intriguing concept: Humans can serve as a valuable resource for understanding the impact on other animal species of the toxic “forever chemicals” known as PFAS.  “PFAS pollution is not just a problem for humans,” said David Andrews, Ph.D., senior scientist at EWG. “It’s a problem for species across the globe. This new paper delves into how humans serve as an early warning system ...

Redwoods and oaks that thrive on California’s coastline and coastal mountains might soon start finding it harder to survive. Human-caused climate change is altering the temperatures and rainfall patterns to which those and other trees are accustomed, and many have already been pushed close to the edge of what they can endure. Identifying suitable new habitats will soon become a matter of life or death for some California native species, according to Lawren Sack, a UCLA professor of ecology and evolutionary biology. But if those trees could talk, where would they tell scientists they wanted to live? In a new study, a team led by Sack and other UCLA biologists ...

ROCHESTER, Minn. — Macrophages are a type of white blood cell that are among the body's first line of defense against infection. In addition to killing harmful microorganisms, macrophages typically can initiate a response against tumors. However, macrophages, like other cells, can enter a state called senescence, which is linked to aging, disease and multiple physiological problems. When cells become senescent, they stop dividing, but they do not die and are not always eliminated from the body. They can linger and accumulate in tissues and may ...

The effective use of data storytelling could positively impact public library managers' approaches to data collection and their advocacy for libraries, according to Kate McDowell, associate professor in the School of Information Sciences at the University of Illinois Urbana-Champaign. However, cultural roadblocks to data storytelling must be addressed for the process to be successful, McDowell discovered in a recently completed study. McDowell discusses her findings in the Public Library Quarterly article, "Library Data Storytelling: Obstacles and Paths Forward." This work is the result of her research project, "Data ...

The proportion of people dying before their time (under the age of 75) is set to rise by nearly 6.5%---30 extra deaths/100,000 of the population annually—with those in the most deprived households experiencing a rate 4 times that of the least deprived. In recent years, the UK has experienced levels of inflation not seen since the 1970s as a result of the war in Ukraine, COVID-19, Brexit and fiscal policy, note the researchers. Poorer households have borne the brunt as they spend a larger proportion of their income on energy, the cost of which has soared. In a bid to mitigate the impact, the UK government introduced a universal Energy Price Guarantee (EPG) and a series of more targeted ...

Overly broad definitions, a lack of appropriate, or any, comparison groups, among other things, in studies looking at the incidence, prevalence, and control of the condition—epidemiology—have distorted the risks, say the researchers. This is further compounded by inclusion of poorly conducted studies into systematic reviews and pooled data analyses that end up overstating the risk yet again, they add.  The likely consequences of this include, but aren’t limited to, increased public anxiety and healthcare spend; misdiagnoses; ...

The findings confound predictions in some quarters that disadvantaged children, who had worse mental health to start with, would be hardest hit. But even if child mental health has become more equal, it worsened, overall, following the pandemic, emphasise the researchers. There is some evidence that declines in mental health during the COVID-19 pandemic may have been greatest among younger people, say the researchers, but the impact on inequalities in child mental health isn’t clear. To explore this further, they analysed 16,361 parental observations of 9272 children in the nationally ...

Autologous haematopoietic stem cell transplantation, or aHSCT for short, is usually used to treat blood cancers, and involves harvesting stem cells from the person’s own bone marrow or blood followed by chemotherapy and antibody treatment. Emerging evidence indicates that it is suitable for treating relapsing-remitting MS— characterised by distinct inflammatory episodes that cause varying degrees of residual disability. But aHSCT has yet to be included in most national clinical guidelines.  The researchers therefore ...
