Good news, everyone!

Climbing mountains or going adventuring in hostile terrain can be dangerous, even life-threatening. But a University of Mississippi marketing professor found the old adage that "with great risk comes great reward" holds clues to why thrill-seeking is so satisfying.

3D printed blood vessels on glass that mimic blood vessel anatomy and the fluid dynamics of blood flow could be an invaluable tool in studying the causes of stroke, new research from a University of Sydney team has found and it has already led to important insights.

Taken orally, the miniature "pills" also contain magnetic particles that make them easy to collect from stool.

Researchers at University Medical Center Maastricht and international partners report that a single shot of the drug zalunfiban given at first medical contact for suspected ST-elevation myocardial infarction (STEMI) improved early blood flow in the blocked artery and reduced the chance of a worse 30-day combined outcome.

There are tall, pointy metal tubes aplenty at Port Canaveral, but one is extra large.

A widely used Internet infrastructure company said that it has resolved an issue that led to outages impacting users of everything from ChatGPT and the online game, "League of Legends," to the New Jersey Transit system early Tuesday.

Hospitals do not always have the opportunity to collect data in tidy, uniform batches. A clinic may have a handful of carefully labeled images from one scanner while holding thousands of unlabeled scans from other centers, each with different settings, patient mixes and imaging artifacts. That jumble makes a hard task—medical image segmentation—even harder still. Models trained under neat assumptions can stumble when deployed elsewhere, particularly on small, faint or low-contrast targets.

Antibiotic resistance is one of the most pressing challenges to global public health as harmful microbes evolve to evade these medications.

Beyond gaming and shopping, the metaverse is poised to reshape the fan experience, giving sports enthusiasts new and immersive ways to connect with their favorite athletes and teams.

Microgravity experienced during spaceflight poses potential health risks to astronauts' cardiovascular systems. Determining how to mitigate these health risks is challenging, as countermeasures are tested in Earth's gravity. But what if there was a way to perform research in microgravity, without leaving the atmosphere?

Spiders of the Clubiona genus, which are among the most important natural enemies of pests found in orchards, are active during the winter. New research in The FEBS Journal reveals the characteristics of antifreeze proteins that these spiders produce that bind to ice crystals and prevent their growth at sub-zero temperatures, which helps the animals avoid freezing.

The "California sober" trend, which involves ditching alcohol in favor of cannabis, is gaining momentum, spreading from Hollywood to health influencers to homes across America. Among the motivations for many adopters is to reduce alcohol use, and a new study on the causal effect of cannabis on alcohol consumption suggests that smoking marijuana may lead people to drink less—in the short term.

Helping communities manage green spaces by understanding how they use and value the area could be an effective way for local governments to tackle the biodiversity crisis, according to a new study from the University of Exeter.

In recent years, organic semiconductor materials have attracted considerable attention as key components for next-generation photoenergy conversion devices and organic solar cells due to their light weight and mechanical flexibility. A crucial factor determining their performance is how photoexcited excitons migrate between molecules, that is, the process of exciton diffusion. However, previous studies have provided only ensemble-averaged information, making it difficult to directly observe the diffusion behavior within individual crystals or nanostructures.

The World Institute of Kimchi has confirmed in a new study that bacteriophages, which were previously considered a "nuisance" during the process of food fermentation, actually play the role of key helpers that facilitate the survival of lactic acid bacteria (LAB).

Researchers at Karolinska Institutet have established a novel transplantation site for islets of Langerhans that enables long-term intravital microscopy of islet physiology in awake mice with exceptional stability.

This autumn, Harjula Hospital in the North Savo Wellbeing Services County piloted an innovative rehabilitation method that combines sound and movement: sonification. In physical therapy and occupational therapy sessions, individuals in rehabilitation practiced movements where they, for example, moved their arm to produce the sound of flowing water, or lifted their lower limb to trigger the call of a cuckoo.

A research team in South Korea has developed a novel gasket technology that enhances both the safety and efficiency of polymer electrolyte membrane fuel cells (PEMFCs) and water electrolyzers (PEMWEs, AEMWEs)—core devices for hydrogen production and utilization—by simultaneously improving mechanical strength and gas-tight sealing.

Starting their period is a big deal for adolescents. It marks a turning point in their lives where puberty becomes the new normal and change is happening all over their bodies. Undoubtedly, adolescents are going to have questions, and for those about period products, safety is the biggest factor.

Ca' Foscari University of Venice is co-directing a major international archaeological mission in the Kasserine region of Tunisia. The excavations, focused on the area of ancient Roman Cillium, on the border with present-day Algeria, concentrate on imposing structures linked to oil production, including two torcularia, olive pressing facilities, one of which has been identified as the second largest Roman oil mill in the entire Empire.

Retailers don't need big financial incentives to get consumers to return used clothing—but they do need the right message. A new peer-reviewed study in the journal Manufacturing & Service Operations Management finds that simply telling consumers their returned items will be "kept out of landfills" significantly increases participation in take-back programs. But when retailers disclose that they may resell those items for profit, participation plummets.

A new study led by the University of Oxford has found evidence that kissing evolved in the common ancestor of humans and other large apes around 21 million years ago, and that Neanderthals likely engaged in kissing too. The findings are published in Evolution and Human Behavior.

A low-fat vegan diet is associated with a significant reduction in greenhouse gas emissions (GHGE) and cumulative energy demand (CED) compared to the Standard American Diet, according to research by the Physicians Committee for Responsible Medicine published in JAMA Network Open.

Chronic wasting disease, a prion protein disease that is fatal in elk, deer, and other cervids, has spread rapidly across the United States since it was first identified in 1967. CWD has now reached Idaho near the Oregon border, causing concern for the Columbian white-tailed deer, a rare subspecies found only in two regions in Oregon.

Instruments typically used to detect the ground motion of earthquakes can also be used to identify the type of aircraft flying far overhead, research by University of Alaska Fairbanks scientists shows. That's because aircraft sound waves also shake the ground, though to a much lesser extent.

A novel cobalt (Co)- and nickel (Ni)-based high-entropy superalloy (CoNi-HESA) capable of withstanding higher operating temperatures could prove a step toward more powerful and fuel-efficient aircraft engines.

A new AI-driven technology developed by researchers at UNIST promises to significantly reduce data transmission loads during image transfer, paving the way for advancements in autonomous vehicles, remote surgery and diagnostics, and real-time metaverse rendering—applications that demand rapid, large-scale visual data exchange without delay.

This parallels the goals of the emerging urban air mobility industry, which hopes to bring autonomous flying vehicles to cities around the world. One company got a head start on doing both with some help from NASA.
