About The Study: This study found that the prevalence of adults with diabetes did not significantly change between 2013 and 2023, but glycemic control among those with diagnosed disease worsened in 2021-2023 after nearly a decade of stability. This trend was most pronounced among young adults. The increase of 1% in mean HbA1c levels and 20% decrease in glycemic control would increase the lifetime risk of cardiovascular events. Potential explanations for these findings include increased sedentary behavior, reduced social support, heightened mental health ...

About The Study: In this cohort study of 46,000 U.S. residents, nearly two-thirds of participants had suboptimal 5-year sleep duration trajectories. Suboptimal sleep duration trajectories were associated with as much as a 29% increase in risk of all-cause mortality. These findings highlight the importance of maintaining healthy sleep duration over time to reduce mortality risk. Corresponding Author: To contact the corresponding author, Kelsie M.

Key Takeaways  Surgical adhesions — internal bands of scar tissue that form between organs or tissues after surgery— can lead to severe complications such as bowel obstructions, chronic pain, and infertility while increasing the difficulty of future operations.  Surgical adhesions negatively impact patient outcomes and drive up health care costs.  There is currently no standard measure of the severity of surgical adhesions or their impact on a patient’s quality of life.  CHICAGO – Scarring is expected after most operations, but surgical adhesions present a unique ...

Age-related macular (AMD) degeneration is a leading cause of vision impairment and blindness in the elderly population. In so-called wet AMD, new, abnormal blood vessels grow in the central part of the retina called macula, which is required for high-acuity central vision, leading to fluid and blood leakage and macular damage or dysfunction. Although wet AMD accounts for a minority of AMD cases, 90% of AMD-related cases of blindness are due to wet AMD. Wet AMD in its early stages can be treated with drugs to reduce the formation of new blood vessels, but this treatment is inefficient in cases where blood vessel formation is already in ...

EAST LANSING, Mich. – Astronomers have long grappled with the question, “How do planets form?” A new collaboration among Michigan State University, Arizona State University and Lawrence Livermore National Laboratory will seek to answer this question with the help of a powerful telescope and high-performance computers.   The team of researchers will use 154 hours on the James Webb Space Telescope, or JWST, to probe the atmospheres of seven planets beyond our solar system – all of which were formed less than 300 million years ago, around the time dinosaurs roamed ...

WASHINGTON — For the first time, researchers have used high-speed laser writing to create lines spaced just 100 nm apart on a glass substrate. The optimized printing approach could enable super-resolution 3D direct laser writing (DLW) of microlenses, photonics crystals, micro-optical devices, metamaterials and more. DLW is an additive manufacturing technique that uses a focused laser beam to selectively solidify, or polymerize, a material with nanoscale precision. DLW typically uses multi-photon polymerization to polymerize materials in a precise, ...

Scientists at VCU Massey Comprehensive Cancer Center have identified an innovative combination of treatment strategies that work collaboratively to effectively kill acute myeloid leukemia (AML) cells, a frequently incurable form of cancer. New research findings — published in the Nature family journal Signal Transduction and Targeted Therapy — suggest that a class of drugs known as MCL-1 (myeloid leukemia cell-1) inhibitors interact with a type of kinase inhibitor that targets the SRC gene to efficiently trigger cell death in AML cells. “Results from this research could add another approach ...

A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health found that mental health visits for patients with depression from high-wealth neighborhoods in Maryland were significantly more likely to happen via telehealth compared to patients with depression from low-wealth neighborhoods in Maryland from mid-2021 through mid-2024. Telehealth visits by phone or web-based teleconferencing became popular during the COVID-19 pandemic after in-person health care options were scaled back and telehealth restrictions relaxed. The researchers investigated how mental health care visits changed from before and over the course ...

Planetary-mass objects (PMOs) are cosmic nomads: they drift freely through space, unbound to any star, and weigh less than 13 times the mass of Jupiter. While they have been spotted in abundance in young star clusters such as the Trapezium Cluster in Orion (Fig. 1), their origin has puzzled scientists. Traditional theories have suggested that they might be failed stars or planets ejected from their solar systems. An international team of astronomers, in collaboration with the University of Zurich (UZH), has used advanced simulations to demonstrate that these enigmatic objects can form directly from the violent interactions of disks around young stars. “PMOs don’t ...

Bacteremia, or blood poisoning, occurs when bacteria overcome the body’s immune defenses. Bacteremia can worsen into sepsis, a condition that accounts for more than 1 in 3 hospital deaths per year. Yet people are routinely exposed to and fight off bacteria from the environment without this deadly series of events occurring. Scientists are trying to figure out exactly how bacteria spread throughout the body to cause systemic infection in the hopes of eventually stopping this process in its tracks. Michael Bachman, M.D., Ph.D., clinical associate professor of pathology and microbiology and immunology at U-M Medical School and former postdoc Caitlyn Holmes, Ph.D., ...

A new analysis of social media posts finds public support for solar energy remains high, though that support declined significantly from 2016 to 2022. The study also found solar power has become an increasingly polarized issue, with the shift in support being driven largely by opposition to solar power among people in regions that lean Republican. “The U.S. saw significant growth in the solar energy sector between 2013 and 2022, but that growth has not been spread evenly across the country – some areas have seen more deployment of solar energy technologies than other areas,” says Serena Kim, corresponding author of ...

Anterior cruciate ligament (ACL) injuries are common, especially among athletes. Each year, over 400 000 ACL reconstruction (ACLR) surgeries are carried out globally. While the success rate of ACLR is reported to be over 90%, a significant number of patients still face issues like revision surgery and long-term osteoarthritis. This has spurred research into better graft materials, and artificial ligaments have emerged as a potential solution. A recent review article published in Engineering delves into the current state and future prospects of artificial ligaments for ACLR.   Artificial ...

1 Gene Variant Is Poised to Cure a Devastating Inherited Disease Scientists compared five families and multiple generations to find a gene variant that prevents COPA Syndrome and opens the door to a new gene therapy for the condition. For more than 15 years, Anthony Shum, MD, a pulmonologist at UC San Francisco, has tried to understand the random path of devastation that a rare genetic condition carves through the families it affects.   While many of those who carry the mutation develop severe lung hemorrhaging as children others never get the disease ...

In the rapidly developing contest between human creativity and artificial intelligence algorithms, professional artists still have an edge in producing more creative AI-assisted artwork than the AI programs themselves or novice artists, according to research published by the American Psychological Association.  The rapid advancement of AI raises some existential questions about the nature of creativity, said lead researcher Paul Seli, PhD, an assistant professor of psychology and neuroscience at Duke University.  “Creativity ...
