Researchers at UNIL’s Department of Ecology and Evolution reveal the existence of social traditions in vervet monkeys. This work was published in iScience on December 19, 2023. British tits have learned from each other how to pierce the lids of milk bottles left on doorsteps. On the island of Koshima, Japanese macaques started washing sweet potatoes to rid them of sand. The animal realm is full of examples of traditions linked to food, tool use or hunting techniques that have spread within specific communities. However, few traditions of social nature, i.e. how individuals interact with each other, have been described. A ...

WASHINGTON, Dec. 19, 2023 – A winter wonderland calls to mind piles of fluffy, glistening snow. But to reach the ground, snowflakes are swept into the turbulent atmosphere, swirling through the air instead of plummeting directly to the ground. The path of precipitation is complex but important to more than just skiers assessing the potential powder on their alpine vacation or school children hoping for a snow day. Determining snowflake fall speed is crucial for predicting weather patterns and measuring climate ...

AI models in health care are a double-edged sword, with models improving diagnostic decisions for some demographics, but worsening decisions for others when the model has absorbed biased medical data. Given the very real life and death risks of clinical decision-making, researchers and policymakers are taking steps to ensure AI models are safe, secure and trustworthy—and that their use will lead to improved outcomes. The U.S. Food and Drug Administration has oversight of software powered by AI and machine learning used in health care and has issued guidance for developers. This includes a call to ensure the ...

About The Study: Although standard artificial intelligence (AI) models improve diagnostic accuracy, systematically biased AI models reduced diagnostic accuracy, and commonly used image-based AI model explanations did not mitigate this harmful effect in this multicenter randomized clinical vignette survey study involving hospitalist physicians, nurse practitioners, and physician assistants from 13 states.  Authors: Michael W. Sjoding, M.D., of the University of Michigan Medical School, and Jenna Wiens, Ph.D., of the University of Michigan, Ann Arbor, are the corresponding authors. To ...

About The Study: In this study of 13,000 patients, few patients undergoing surgical procedures completed preoperative life-sustaining treatment documentation, with disparities in documentation rates based on race, ethnicity, rurality of patient residence, history of mental health disability, and access to high-volume facilities within a Veterans Affairs cohort. Authors: Adela Wu, M.D., of the U.S. Department of Veterans Affairs, in Palo Alto, California is the corresponding author.

About The Study: This study found that patients screened in the emergency department (ED) were more likely to screen positive for Social Determinants of Health (SDOH) needs, which is not surprising given utilization patterns. Patients with SDOH needs have limited health care access and are more likely to use the ED than primary care. Although primary care–based screening found lower SDOH needs relative to the ED, primary care may be better optimized to follow and ultimately address SDOH needs. Authors: Stacie ...

Humans have wiped out around 1,400 bird species – twice as many as previously thought – with major implications for the ongoing biodiversity crisis, a new study has found. Many of the world’s islands were previously untouched paradises, but the arrival of people to places like Hawaii, Tonga and the Azores led, over time, to far-reaching impacts including deforestation, overhunting and the introduction of invasive species. Consequently, bird species were wiped out. While the demise of many birds since the 1500s has been recorded, our knowledge of the fate of species before this relies on fossils, ...

For example, the world of genetics has opened doors to a myriad of possibilities: augmented human capabilities, cures for diseases, and even changes to the course of evolution. In a study published last month in Communications Medicine, researchers from Tokyo Medical and Dental University (TMDU) have unveiled a groundbreaking genome-editing technique. This ...

Kyoto, Japan -- Down syndrome, a congenital disorder stemming from abnormal cell division and differentiation, is most common in newborns fated to neurodevelopmental delays and other health complications. The genetic defect causes the dysfunction of the protein kinase DYRK1A, which is encoded on chromosome 21 and is deeply associated with both Down syndrome and autism spectrum disorder. DYRK1A has attracted attention as a target molecule for treating various diseases, but specific cellular mechanisms regulating ...

Kyoto, Japan – December 2023   Anxiety disorders (ADs) affect more than 280 million people worldwide, making them one of the most common mental health conditions. ADs have a genetic basis as seen from inheritance in families, and people with one subtype of AD tend to have another subtype, suggesting a shared genetic basis. Although the brain circuitry involved in ADs has been identified, its link with gene expression remains unclear. Two researchers at Kyoto University in Japan set out to uncover this link and found two gene clusters expressed in ...

Using a novel experimental approach, Max Planck researchers have discovered a core set of genes required by commensal bacteria to colonize their plant hosts. The findings may have broad relevance for understanding how bacteria establish successful host–commensal relationships. Plants are colonized by an enormous variety of microorganisms, including bacteria, archaea and fungi, that form complex communities, or microbiomes, on their roots and organs. Although invisible to the naked eye, the importance of these tiny inhabitants should not be underestimated. They play a crucial role in plant nutrition, influence the health of plants, strengthen their tolerance to stress factors such as ...

A new study provides the latest data on the low rates for screening and documenting Social Determinants of Health (SDOH) in healthcare settings. SDOHs are a person's social, environmental and economic conditions highly correlated with their health outcomes. This includes unemployment, homelessness and illiteracy, among many other factors. Although SDOHs can contribute to a more comprehensive understanding of a patient's health and inform important policy changes, clinical offices fall short of tracking this information. To better understand ...

CLEVELAND—Throughout our lives, changes in our DNA, called genetic mutations, occur in every healthy cell of the human body—mutations which have long been thought to be an important reason why our bodies age. But it’s not known whether some people accumulate mutations at a faster or slower rate with age, and whether those differences might predict how long we live and the risk for aging-related diseases like cancer. With a $3.5 million research project grant from the National Institutes of Health (NIH), Jonathan Shoag, a surgeon-scientist at the Case Western Reserve University School of Medicine and urologic oncologist at ...

How is cooperation affected when people can receive secondhand information about what others are contributing? Ashley Harrell and Tom Wolff investigated this question through an online cooperation game. Participants were recruited from a large subject pool of university students and other adults, maintained by the Interdisciplinary Behavioral Research Center at Duke University. Over 200 participants were placed in groups of 6–10; however, each participant was only linked to some of the other participants. In the control condition, players could only see the contributions ...

COLUMBUS, Ohio – New technology has allowed scientists to see how a major sporting event can disrupt public transportation in an entire city for hours before and after the event.   Researchers conducted a case study in Columbus on days that The Ohio State University had home football games, attracting more than 100,000 fans to Ohio Stadium on the university’s campus.   Findings showed that bus service across the entire city was significantly less reliable for more than 7 hours on game days compared to other days, meaning that even bus riders who were not traveling near the university ...

In a perspective, Athanassios S. Fokas considers a timely question: whether artificial intelligence (AI) can reach and then surpass the level of human thought. Typically, researchers have sought to measure the ability of computer models to accomplish complex goals, such as winning the game of Go or carrying on a conversation that seems human enough to fool an interlocutor. According to Fokas, this approach has a key methodological limitation. Any AI would have to be tested on every single conceivable human goal before anyone could claim that the program was thinking as well as a human. Alternative methodologies are therefore needed. In addition, the “complex goal” focus does not ...

In an editorial, Monica M. Bertagnolli assesses the promise of artificial intelligence and machine learning (AI/ML) to study and improve health. The editorial was written by Dr. Bertagnolli in her capacity as director of the National Cancer Institute. AI/ML offer powerful new tools to analyze highly complex datasets, and researchers across biomedicine are taking advantage. However, Dr. Bertagnolli argues that human judgment is still required. Humans must select and develop the right computational models and ensure that the data used to train ...

Bethesda, MD (Dec. 19, 2023) — The American Gastroenterological Association (AGA) has released the first comprehensive evidence-based guideline on the management of pouchitis, the most common complication people with ulcerative colitis experience following surgery to remove their colon.   Between 150,000 and 300,000 people with ulcerative colitis in the U.S. live with a surgically created internal reservoir or “pouch” created from their small intestine as an alternate way to store and pass ...

Scientists have so far identified around 800 different neuromuscular diseases. These conditions are caused by problems in the way muscle cells, motor neurons and peripheral cells interact. These disorders, including amyotrophic lateral sclerosis and spinal muscular atrophy, lead to muscle weakness, paralysis, and in some cases death. “These diseases are highly complex, and the causes of the dysfunction can vary widely,” says Dr. Mina Gouti, head of the Stem Cell Modeling of Development and Disease Lab at the Max Delbrück Center. The problem might lie with the neurons, the muscle cells or the connections between the two. ...

Addressing climate change has become a central issue in Chile’s public policy. As part of that debate, Dr. Maisa Rojas, researcher in Atmospheric Physics, who currently serves as Chilean Minister for Environment and Marco Billi of the Centre for Climate and Resilience Research, Universidad de Chile, propose a new model of governance at the country level to facilitate the changes needed. The proposal – written before Dr. Rojas’ appointment to the Chilean government – is published in IOP Publishing’s journal Environmental Research Letters.   The model proposed places climate action ...

Physical, sexual, or emotional abuse, or neglect, either alone or combined with other types of childhood trauma, increases the risk of chronic pain and related disability in adulthood, according to new research.    These new findings underscore the urgency of addressing adverse childhood experiences (ACEs) – potentially traumatic events that occur before 18 years of age – and taking steps to mitigate their long-term impact on people’s health.    The study ...

Pandas, long portrayed as solitary beasts, do hang with family and friends – and they’re big users of social media. Scent-marking trees serve as a panda version of Facebook. An article in the international journal Ursus paints a new lifestyle picture of the beloved bears in China’s Wolong Nature Reserve, a life that’s shielded from human eyes because they’re shy, rare, and live in densely forested, remote areas. No one really knows how pandas hang, but a new study indicates pandas are around others ...
