Study: Rainfall variability increased with warming in northern Queensland, Australia over the past 280 years (DOI: 10.1038/s43247'024 -01262-5) (available when embargo lifts) When climate scientists look to the future to determine what the effects of climate change may be, they use computer models to simulate potential outcomes such as how precipitation will change in a warming world.

Easily interpretable technique can reduce the cost and increase the scale of protein optimization for applications in medicine, biofuels and more Study: Machine learning to predict continuous protein properties from binary cell sorting data and map unseen sequence space (DOI: 10.1073/pnas. A protein engineering method using simple, cost-effective experiments and machine learning models can predict which proteins will be effective for a given purpose, according to a new study by University of Michigan researchers.

It looks like the same mechanism that breaks up airplane contrails might be at play in forming the clumps of hydrogen gas that ring the remnant of supernova 1987A Study: Hydrodynamic mechanism for clumping along the equatorial rings of SN1987A and other stars (DOI: 10.1103/PhysRevLett. Physicists often turn to the Rayleigh-Taylor instability to explain why fluid structures form in plasmas, but that may not be the full story when it comes to the ring of hydrogen clumps around supernova 1987A, research from the University of Michigan suggests.

Use of the psychoactive cannabis product is higher in states without existing delta-8 regulations or cannabis legalization, study finds Study: Adolescent Delta-8-THC and Marijuana Use in the United States (DOI: 10.1001/jama. The first ever national estimates of teen delta-8 use indicate that 11% of 12th grade students across the United States used it in the past year.

Study: Unraveling the interplay of circadian rhythm and sleep deprivation on mood: A Real-World Study on first-year physicians It's always darkest before the dawn for many people, and now, a University of Michigan and Dartmouth Health study has looked into the science of waking up on the wrong side of the bed.

Study: The kainite receptor GluK2 mediates cold sensing in mice (DOI: 10.1038/s41593'024 -01585-8 ) University of Michigan researchers have identified the protein that enables mammals to sense cold, filling a long-standing knowledge gap in the field of sensory biology. The findings, published in Nature Neuroscience, could help unravel how we sense and suffer from cold temperature in the winter, and why some patients experience cold differently under particular disease conditions.

Study: When social media attack: How exposure to political attacks on social media promotes anger and political cynicism Political anger and cynicism are rising in the United States and in many democracies worldwide, and both are associated with exposure to political attacks on social media, a new University of Michigan study shows.

Study: A Practical Significance Bias in Laypeople's Evaluation of Scientific Findings (DOI: 10. When media coverage doesn't include the numerical magnitude of a scientific study's effect, the risk of people having biases increases significantly, according to a new University of Michigan study. People may incorrectly assume that the findings are of greater importance and impact than they are without the numerical information from media outlets, researchers said.

A team of University of Michigan researchers has successfully modified a naturally occurring chemical compound in the lab, resulting in advanced lead compounds with anti-HIV activity. Their results, in the Journal of Medicinal Chemistry, offer a new path forward in the development of drugs that could potentially help cure-rather than treat-HIV.

Site features interactive maps, testimonies collected by The Reckoning Project The University of Michigan's Weiser Center for Europe and Eurasia has created a new that serves as a digital archive of testimonies from witnesses and victims of documented human rights violations, war crimes and atrocities in Ukraine since Russia's full-scale invasion on Feb.

Study: Dual phosphorylation of DGK5-mediated PA burst regulates ROS in plant immunity When pathogens attack plants, the plant cells almost immediately react. The plant's cells begin to produce different kinds of small molecules called secondary messengers. These messengers travel throughout the cell membrane to begin the process of activating the immune system.

Study (PDF): Exposure to Community Violence as a Mechanism Linking Neighborhood Disadvantage to Amygdala Reactivity and the Protective Role of Parental Nurturance Living in neighborhoods with high levels of violence can affect children's development by changing the way that a part of the brain detects and responds to potential threats, which could lead to poorer mental health and other negative outcomes.

While the merits of charter schools vs. traditional public schools are well-documented, some charter schools in urban areas can dramatically improve student achievement, especially among disadvantaged students, says a University of Michigan researcher. Sarah Cohodes , associate professor of public policy at U-M's Ford School of Public Policy, and colleague Susha Roy of the RAND Corporation analyzed 40 previous charter school studies that used admission lotteries to compare similar students who did or did not enroll.

Student enrollment in districts that provided in-person schooling in fall 2020 during the COVID-19 pandemic showed a greater decline among nonwhite students than white students. But in districts that offered virtual learning, the opposite was true, according to a University of Michigan study. The results , published in the journal PNAS, are consistent with the fact that communities of color faced greater risks from COVID-19 and reported less trust in medical and social institutions.

When using only data collected before patients with sepsis received treatments or medical tests, the model's accuracy was no better than a coin toss Study: Evaluation of Sepsis Prediction Models before Onset of Treatment (DOI: 10.1056/AIoa2300032) Proprietary artificial intelligence software designed to be an early warning system for sepsis can't differentiate high and low risk patients before they receive treatments, according to a new study from the University of Michigan.

Study abstract: Firearm manufacturing and imports in the USA and their association to firearm homicides in Central America and the Caribbean, 1991-2019 When the United States manufactures and imports more firearms, firearm homicide rates in Central American and Caribbean countries also increase, a study led by University of Michigan researchers found.

Study: The social anatomy of climate change denial in the United States DOI 10.1038/s41598'023 -50591-6 (available once embargo lifts) Using social media data and artificial intelligence in a comprehensive national assessment, a new University of Michigan study reveals that nearly 15% of Americans deny that climate change is real.

University of Michigan researchers are celebrating their discovery of a new plant biochemistry and its unusual ability to form cyclic peptides-molecules that hold promise in pharmaceuticals as they can bind to challenging drug targets. Cyclic peptides are an emerging and promising area of drug research.

Ninety-four percent of Michigan nurses report emotional exhaustion, with younger nurses significantly more likely to report burnout than colleagues over 45, according to a University of Michigan School of Nursing survey. "I've been studying nurse burnout for 20 years and these are among the highest numbers I've seen,- said principal investigator Christopher Friese , U-M professor of nursing and public health.

Study: Detection of Earthquake Infragravity and Tsunami Waves with Underwater Distributed Acoustic Sensing Fiber optic cables that line ocean floors could provide a less expensive, more comprehensive alternative to the current buoys that act as early warning systems for tsunamis, says a University of Michigan researcher.
