Mass General Brigham study reveals that ED visits and death are heightened weeks after major climate-driven extreme weather events – highlighting the long-lasting impacts these events may have on health and infrastructure
UT Southwestern Medical Center researchers have developed an artificial intelligence (AI) method that writes its own algorithms and may one day operate as an "automated scientis" to extract the meaning behind complex datasets.
In a paper published in Nature Cities, a research team explored the role that population size of cities plays on the incidences of gun homicides, gun ownership and licensed gun sellers. The researchers found that none of these quantities vary linearly with the population size. In other words, higher population did not directly equate to proportionally higher rates of gun homicides, ownership, or gun sellers in a predictable straight-line way across cities. The relationships were more complex than that.

The colon is often thought of as one organ, but the right and left parts of the colon have different molecular features in cancers. New research in mice from investigators at the Johns Hopkins Kimmel Cancer Center demonstrates that these regions also have distinct transcriptional programs, or cellular processes, that regulate the development of normal and cancerous cells.
In a first-of-its-kind study, researchers at the Georgia Institute of Technology discovered that sea cucumbers — sediment-eating organisms that function like autonomous vacuum cleaners of the ocean floor — play an enormous role in protecting coral from disease. The problem is, they've been overharvested for more than 100 years, and they're now rare.

With time scheduled to use a certain beamline at the National Synchrotron Light Source-II (NSLS-II), scientists from NSLS-II and their partner institutions faced a challenge. They planned on researching a special type of region in magnetic materials that could be useful for next-generation computers. Regions in magnetic materials - called magnetic domains - determine a material's magnetic properties. The scientists wanted to study how these magnetic domains changed over time under the influence of an outside magnetic field.
In a new paper published in the journal Nature, Michigan State University researchers Robert Quinn and Doug Guzior report the discovery of the enzyme responsible for producing microbially conjugated bile acids, some of the most abundant and crucial molecules in our gut.
About eight million people live with Type 1 diabetes (T1D) worldwide, a chronic autoimmune condition in which the body attacks and destroys its own insulin-producing β-cells (pronounced “beta”) in the pancreas, leading to a lack of insulin and inability to regulate blood sugar. It’s not known why the body suddenly perceives its own β-cells as the enemy; some lines of evidence suggest environmental factors such as viral infections may trigger the onset of T1D, others suggest genetics may also play some role. Groundbreaking research by investigators at Joslin Diabetes Center sheds new light on the specific changes β-cells go through at the onset of T1D. Their findings—published in Nature Cell Biology—offer new avenues for targeted interventions for the chronic autoimmune condition.
The idea that people make decisions based on social context is not a new one in neural economic games. But now, for the first time, researchers publishing in Nature Human Behavior show the impact of the social context may spring from the dynamic interactions of dopamine and serotonin. Researchers built carbon-fiber electrodes that were implanted in patients receiving Deep Brain Stimulation surgery. The method allows researchers to measure more than one neurotransmitter at a time, revealing a dance that has never been seen before
From the invention of the wheel to the advent of the printing press to the splitting of the atom, history is replete with cautionary tales of new technologies emerging before humanity was ready to cope with them.

Scientists report a major step toward a simple blood test for Alzheimer’s disease. Researchers at Washington University School of Medicine in St. Louis and Lund University in Sweden showed that a blood test is as good at identifying people in early stages of the disease as cerebrospinal fluid tests approved by the Food and Drug Administration (FDA) for Alzheimer’s diagnosis. The findings indicate that a blood test soon may replace more expensive and invasive brain scans and spinal taps for detecting signs of Alzheimer’s in the brain.
Systemic sclerosis causes the skin to tighten and harden resulting in a potentially fatal autoimmune condition that is associated with lung fibrosis and kidney disease. University of Michigan Health researchers have studied the pathology of systemic sclerosis to understand better the disease and identify key pathways in the disease process that can be targeted therapeutically.

Weedy rice is an agricultural pest with a global economic impact. It is an aggressive weed that outcompetes cultivated rice and causes billions of dollars in yield losses worldwide. A study from Washington University in St. Louis offers new insights into genetic changes that give weedy rice its edge over cultivated rice in tropical regions of the world.
Membranes of vertically aligned carbon nanotubes (VaCNT) can be used to clean or desalinate water at high flow rate and low pressure. Recently, researchers of Karlsruhe Institute of Technology (KIT) and partners carried out steroid hormone adsorption experiments to study the interplay of forces in the small pores. They found that VaCNT of specific pore geometry and pore surface structure are suited for use as highly selective membranes. The researchers report in Nature Communications. (DOI: 10.1038/s41467-024-44883-2)
