Skin-inspired organic biosensors can reliably track health-related signals in real-time

The rapid advancement of sensing and artificial intelligence (AI) systems has paved the way for the introduction of increasingly sophisticated wearable devices, such as fitness trackers and technologies that closely monitor signals associated with specific diseases or medical conditions. Many of these wearable electronics rely on so-called biosensors, devices that can convert biological responses into measurable electrical signals in real-time.

While and other are now widely used, the signals that many existing devices pick up are sometimes inaccurate or distorted. This is because the bending of sensors, moisture and temperature fluctuations sometimes produce inaccurate readings and drifts (i.e., gradual changes that are unrelated to a measured signal).

Researchers at Stanford University have developed new skin-inspired biosensors based on organic field effect transistors (OFETs), devices based on organic semiconductors that control the flow of current in electronics.

Chemists discover antibiotic for drug-resistant bacteria ‘hiding in plain sight’

Chemists from the University of Warwick and Monash University have discovered a promising new antibiotic that shows activity against drug-resistant bacterial pathogens, including MRSA and VRE

Antimicrobial resistance (AMR) is one of the world’s most urgent health challenges, with the WHO’s new report showing there are ‘too few antibacterials in the pipeline. Most of the ‘low-hanging fruit’ has already been found, and the limited commercial incentives deter investment in antibiotic discovery.

In a study published in the Journal of the American Chemical Society, researchers from the Monash Warwick Alliance Combating Emerging Superbug Threats Initiative have discovered a promising new antibiotic—pre-methylenomycin C lactone.

Turning Point in Heart Health Occurs at 1 Key Age (It’s Younger Than You’d Think)

Emerging adulthood – the life stage that unfolds around ages 18–25 – is full of major transitions, such as starting college or learning a trade, making new friends and romantic connections, and generally becoming more independent.

It’s also a stage where behaviors that diminish heart health, such as spending more time sitting, consuming more fast food, and using more tobacco and alcohol, become more common.

In fact, only about 1 in 4 youths maintain positive health behavior patterns during the transition to adulthood.

Scientists smash record in stacking semiconductor transistors for large-area electronics

King Abdullah University of Science and Technology (KAUST; Saudi Arabia) researchers have set a record in microchip design, achieving the first six-stack hybrid CMOS (complementary metal-oxide semiconductor) for large-area electronics. With no other reported hybrid CMOS exceeding two stacks, the feat marks a new benchmark in integration density and efficiency, opening possibilities in electronic miniaturization and performance.

A paper detailing the team’s research appears in Nature Electronics.

Among microchip technologies, CMOS microchips are found in nearly all electronics, from phones and televisions to satellites and medical devices. Compared with conventional silicon chips, hybrid CMOS microchips hold greater promise for large-area electronics. Electronic miniaturization is crucial for flexible electronics, smart health, and the Internet of Things, but current design approaches are reaching their limits.

Physical activity raises daily calorie burn without conserving energy used elsewhere, study finds

The effects of physical activity don’t stop when the movement does. In a new study published in the Proceedings of the National Academy of Sciences, Virginia Tech researchers, in collaboration with researchers at the University of Aberdeen and Shenzhen University, have found that being active adds to the total energy you use every day without causing the body to conserve energy in other ways.

This is important because the health benefits of increasing are already well-documented, but there is less research about how exercise impacts a person’s “energy budget,” or the allocation of energy to different bodily functions.

It has been thought that a person’s energy budget functions in one of two ways: like a fixed salary where energy is redistributed from other functions to cover the cost of movement, or like a flexible, commission-based system that is additive and allows for increased . The team wanted to determine which model better explains how the energy budget actually changes across different levels of physical activity.

Scientists Discover Exercise Literally Rewires Your Body at the Molecular Level

Exercise reprograms molecular pathways in the body, offering new clues for future disease prevention and treatment. For years, it has been well established that regular exercise builds strength, improves cardiovascular health, and boosts mood. Now, new research reveals that its benefits go even d

A hitchhiker’s guide to the galaxy of space immunology

With the advent of commercial spaceflight, an increasing number of people may be heading into space in the coming years. Some will even get a chance to fly to the moon or live on Mars.

One of the major health risks associated with spaceflight involves the immune system, which normally fights off viruses and cancer. It’s already established that spaceflight weakens immunity; current and past astronauts report clinical issues such as respiratory illnesses and skin rashes. These issues may become even more serious on longer-term flights, such as to Mars.

To better understand the full scope of immunology during spaceflight, Buck Associate Professor Dan Winer, MD, working with colleagues linked to the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), Cornell University, the University of Pittsburgh, the University of Toronto, Embry-Riddle Aeronautical University, and others, have put together a comprehensive guide describing a full array of science linking spaceflight and the immune system.

Insights into Persistent SARS-CoV-2 Reservoirs in Chronic Long COVID

Long COVID (LC), also known as post-acute sequelae of COVID-19 infection (PASC), is a heterogeneous and debilitating chronic disease that currently affects 10 to 20 million people in the U.S. and over 420 million people globally. With no approved treatments, the long-term global health and economic impact of chronic LC remains high and growing. LC affects children, adolescents, and healthy adults and is characterized by over 200 diverse symptoms that persist for months to years after the acute COVID-19 infection is resolved. These symptoms target twelve major organ systems, causing dyspnea, vascular damage, cognitive impairments (“brain fog”), physical and mental fatigue, anxiety, and depression. This heterogeneity of LC symptoms, along with the lack of specific biomarkers and diagnostic tests, presents a significant challenge to the development of LC treatments.
