In what is believed to be the first study of its kind, University of Michigan researchers dug deeper into the numbers-only data of COVID-19-era suicides and evaluated the narratives contained in reports from coroners, medical examiners, police and vital statistics.   The researchers sought to understand how the crisis influenced suicide deaths in the first year of the pandemic, how the response by governments, employers and others influenced individuals, and if their handling could inform future public health responses.   "Our study adds much-needed context and meaning to the data that have assumed the deaths are ...

Soil plays a much bigger role in the spread of antibiotic resistance than one might imagine. Surprisingly, the ground beneath us is packed with antibiotic resistance genes (ARGs) — tiny codes that allow bacteria to resist antibiotics. Human activities, such as pollution and changing land use, can disturb soil ecosystems and make it easier for resistance genes to transfer from soil bacteria and infect humans. Jingqiu Liao, assistant professor in civil and environmental engineering, is on a mission to understand how soil bacteria contribute to ...

For parents trying to shield their children from online threats, limiting screen time is a common tactic. Less time scrolling, the rationale goes, means less exposure to the psychological dangers posed by social media.  But research from Rutgers University-New Brunswick upends this assumption. Writing in The Journal of Child Psychology and Psychiatry, Jessica L. Hamilton, an assistant professor in the Department of Psychology at the School of Arts and Sciences, reports that screen time ...

In a recent study published in Engineering, a team of researchers led by Wenyu Zhang from South China Agricultural University has developed a groundbreaking cotransporter system that combines a tracked rice harvester and transporter for fully autonomous harvesting, unloading, and transportation operations. The key innovation of this system lies in the proposed dual-unloading mode, which includes two distinct methods: harvester waiting for unloading (HWU) and transporter following for unloading (TFU). In the HWU system, the harvester halts and summons the transporter when its ...

Physicists have long theorized the existence of a unique state of matter known as a quantum spin liquid. In this state, magnetic particles do not settle into an orderly pattern, even at absolute zero temperature. Instead, they remain in a constantly fluctuating, entangled state. This unusual behavior is governed by complex quantum rules, leading to emergent properties that resemble fundamental aspects of our universe such as the interactions of light and matter. Despite its intriguing implications, experimentally proving ...

SPOKANE, Wash. – Adding strong evidence in support of “walkable” neighborhoods, a large national study found that the built environment can indeed increase how much people walk. The study, published in the American Journal of Epidemiology, showed a strong connection between place and activity by studying about 11,000 twins, which helps control for family influences and genetic factors. The researchers found that each 1% increase in an area’s “walkability” resulted in 0.42% increase in neighborhood walking. When scaled up, that means a 55% increase in the walkability of the surrounding neighborhood ...

Breast tissue that appears white on ...

Virtually every cell in the human body has an internal clock. These clocks take their cues from a central clock in the brain. In a normal, biological process called synchrony, the central clock coordinates daily rhythms around the body, so that every cell and tissue recognizes the same external time of day. Knowing local time helps our bodies to regulate essential processes, including when to sleep and wake, when to eat and what temperature to maintain, among many other important functions. But a deadly interloper is keeping time the same ...

Genetic variants that determine the shape of your teeth – including a gene inherited from Neanderthals – have been identified by a team co-led by UCL researchers. In a new paper published in Current Biology, scientists found substantial tooth differences between ethnicities, potentially due in part to a gene inherited from Neanderthals that was only found in study participants of European origin. Co-lead author Dr Kaustubh Adhikari (UCL Genetics, Evolution & Environment and The Open University) said: “Teeth ...

Whether they’re lifelong buddies or recently connected, close to home or miles away, a new poll shows the key role that friends play in the lives and wellbeing of adults aged 50 and older. But it also reveals some challenges for those who have physical health or mental health issues – suggesting it may be important for them connect with existing friends or make new friends. In all, 90% of people aged 50 and older say they have at least one close friend, and 75% say they have enough close friends, ...

Excessive screen use by preschool-age children can lead to reduced sleep quality, exacerbating problems such as poor attention, hyperactivity and unstable mood, a new study suggests. Peer-reviewed findings published in Early Child Development and Care show how screen time is “significantly” correlated with increased hyperactive attention problems and emotional symptoms, and with decreased sleep quality. Additionally, the research – carried out by experts in China and Canada – demonstrates how sleep quality is also extensively correlated with decreased hyperactive attention problems, emotional symptoms and peer problems. The findings ...

Sweetpotatoes are an agricultural powerhouse that feeds millions globally. However, their complex genetics make it challenging for breeders to understand and improve traits like yield, disease resistance, and nutritional content. A new study reveals insights into the significance of leveraging “allele dosages” in sweetpotato breeding practices. “Sweetpotatoes are hexaploid, meaning they have six copies of each chromosome, unlike diploid crops like tomato or rice, which have two," explained Zhangjun Fei, a professor at the Boyce Thompson Institute and one of the study's lead authors. “This genetic ...

DILI is broadly categorized into intrinsic and idiosyncratic types. Intrinsic hepatotoxins, such as APAP, cause dose-dependent injury, while idiosyncratic DILI involves complex immune and metabolic interactions that remain poorly understood. Mechanistic studies of intrinsic hepatotoxins have revealed oxidative stress and mitochondrial dysfunction as key contributors to injury. Historically, LPO and iron-catalyzed free radical generation were central to understanding DILI, but the focus shifted toward apoptosis in the late 20th century. The discovery of ferroptosis—a regulated form of cell death characterized ...
