Southern Ocean warming will mean a wetter West Coast, US
|
As global temperatures warm, the Southern Ocean -- between Antarctica and other continents -- will eventually release heat absorbed from the atmosphere, leading to projected long-term increases in precipitation over East Asia and the Western U.S., regardless of climate mitigation efforts.

Novel point-of-care technology delivers accurate HIV results in minutes
|
The technology described uses a nanomechanical platform and tiny cantilevers to detect multiple HIV antigens at high sensitivity in a matter of minutes. These silicon cantilevers are cheap and easy to mass produce and can be readily equipped with a digital readout. Built into a solar-powered device, this technology could be taken to hard-to-reach parts of the world where early detection remains a challenge to deliver fast interventions to vulnerable populations without waiting for a lab.

Study finds nearly five-fold increase in hospitalizations for common cause of stroke
|
Cervical artery dissection is a tear in an artery in the neck that provides blood flow to the brain. Such a tear can result in blood clots that cause stroke. A new study has found almost a five-fold increase in the number of U.S. hospitalizations for cervical artery dissection over a 15-year period.

Scientists unveil starfish-inspired wearable tech for heart monitoring
|
When we move, it's harder for existing wearable devices to accurately track our heart activity. But researchers found that a starfish's five-arm shape helps solve this problem. Inspired by how a starfish flips itself over -- shrinking one of its arms and using the others in a coordinated motion to right itself -- scientists have created a starfish-shaped wearable device that tracks heart health in real time.

Galaxies die earlier than expected
|
For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe. The James Webb space telescope now reveals that galaxies stopped forming stars earlier than expected. A recent discovery deepens the tension between theoretical models of cosmic evolution and actual observations. Among hundreds of spectra obtained with the Webb program RUBIES, the team has found a record-breaking galaxy that had already stopped forming stars during an epoch where galaxies are normally growing very rapidly.

An AI model trained on large amounts of genetic data can predict whether bacteria will become antibiotic-resistant. The new study shows that antibiotic resistance is more easily transmitted between genetically similar bacteria and mainly occurs in wastewater treatment plants and inside the human body.

Precious metals are not merely ornaments; they are also important components of pharmaceuticals, like the antitumor drug cisplatin. Recently, the search for alternatives with improved activity has begun to focus on gold. A research team has now published a study about the speciation and distribution of an organogold(III) complex in cancer cells and reveals how specially designed 'organogold' complexes might open exciting avenues for fighting cancer.

Seeing humanity's transition from hunting to farming as a cultural shift
|
Using a mathematical model, researchers have shed new light on the transition from hunter-gatherer to farming societies. Rather than focusing exclusively on external factors, they looked at internal demographics and the significant impact of human interactions. The model identified potential societal outcomes based on demographic changes, emphasizing aspects such as migration rates, cultural assimilation and the role of mortality in these transitions. The researchers aim to further develop their model with the aim of making it a standard tool for studying historical demographic interactions.

Metamaterials: Highly twisted rods store large amounts of energy
|
An international research team has developed mechanical metamaterials with a high elastic energy density. Highly twisted rods that deform helically provide these metamaterials with a high stiffness and enable them to absorb and release large amounts of elastic energy. The researchers conducted simple compression experiments to confirm the initial theoretical results.

Plant doctor: An AI system that watches over urban trees without touching a leaf
|
Monitoring urban plant health traditionally requires extensive manual labor and botanical expertise, creating challenges for cities facing expanding green spaces, higher population densities, and increasing threats to plants. Now, researchers have developed 'Plant Doctor,' an artificial intelligence-based tool that could revolutionize plant health monitoring. The proposed system can track individual leaves in urban video footage and precisely quantify the damage from pests and diseases, enabling scalable, non-invasive urban plant management.

How the brain evaluates rewards
|
Researchers have gained a new understanding of how the brain processes reward and risk information. Neuroscientists show how nerve cells in the so-called amygdala not only encode the probability and magnitude of rewards, but also dynamically process this information to predict value and risk. The findings provide new insights into the neural basis of decision-making and could also be important for understanding mental illnesses such as anxiety disorders and depression.

When it comes to obesity-related cancers, where you shop for food matters
|
Obesity is at epidemic proportions in the United States where more than 40% of adults are obese and more than 70% are overweight. One common policy intervention to tackle this urgent issue is to try to improve diet quality by increasing local grocery stores that offer healthy options. However, this is not a silver bullet, but researchers are not sure why. A team of researchers developed a novel tool to help understand consumer behavior at the county level, and to study the relationship between where people shop for their food and the risk of obesity-related cancers.

Miso is a traditional Japanese condiment made by fermenting cooked soybeans and salt. Researchers successfully made miso on the International Space Station (ISS). They found that the miso smelled and tasted similar to miso fermented on Earth -- just with a slightly nuttier, more roasted flavor. The team hopes this research will help broaden the culinary options available to astronauts, improving the quality of life for long-term space travelers.

World's smallest pacemaker is activated by light
|
Smaller than a grain of rice, new pacemaker is particularly suited to the small, fragile hearts of newborn babies with congenital heart defects. Tiny pacemaker is paired with a small, soft, flexible wearable patch that sits on the patient's chest. The wearable patch detects irregular heartbeats and automatically emits pulses of light. The light then flashes on and off at a rate that corresponds to the correct pacing. After the tiny pacemaker is no longer needed, it dissolves inside the body.

Rates of breast and colorectal cancer screening nearly four-fold higher than lung cancer screening among those eligible
|
Lung cancer screening has the potential to catch lung cancer early and save lives -- but only if people get screened. Although lung cancer screening is recommended in the U.S. for certain individuals with a history of smoking, only 18% of eligible individuals in the U.S. get screened. One suggested explanation has been that those eligible are resistant to receiving preventive healthcare, but a new study indicates otherwise.
