Your clothes may become smarter than you

You’re probably used to the sight of smartwatches on people’s wrists. But what about smart clothes? Researchers at the University of Georgia are exploring how the clothes people wear can potentially track and protect their health. Smart textiles are fabrics that can monitor the body’s vitals and movement in real time. They’re flexible and lightweight, making them more comfortable to wear while moving.

The present publication focuses on MXenes, a class of two-dimensional, microscopic materials made from metals that can be coated or printed onto fabrics. The researchers conducted a comprehensive analysis of hundreds of published studies to examine the different properties of MXenes and how they could be used in smart textiles. The paper is published in the journal ACS Omega.

“MXenes have some advanced properties,” said Joyjit Ghosh, corresponding author of the study and a doctoral student in UGA’s College of Family and Consumer Sciences. Not only can they detect body temperature, blood pressure and heart rate, he said, but they are also antimicrobial, making them ideal for hospital settings.

Belt-like VO₂(B) single crystals unlock high-sensitivity gas detection at room temperature

An international research team has successfully synthesized oriented belt-shaped vanadium dioxide (VO2(B)) single crystals via a hydrothermal reduction method, using one-dimensional vanadium pentoxide (V2O5) nanofibers as the starting material. This work, published in the journal ACS Sensors, provides a new material platform and design guidelines for the development of next-generation low-power gas sensors capable of operating at room temperature.

Volatile organic compounds (VOCs) emitted from industrial activities and vehicle exhaust are major urban air pollutants. Because VOCs pose serious environmental and health risks, developing effective monitoring for them is a global concern. Gas sensors can monitor for VOCs, but it has been a major challenge for scientists to develop sensors that work reliably at room temperature. Currently, metal oxide semiconductor gas sensors operate at 200°C–400°C.

“This heating requirement greatly increases power consumption and limits their use in portable devices, battery-powered systems, and large-scale Internet of Things sensor networks,” said Professor Shu Yin from the Institute of Multidisciplinary Research for Advanced Materials (IMRAM), Tohoku University (also affiliated with the Advanced Institute for Materials Research, WPI-AIMR).

New NMR method allows the observation of chalcogen bonds

Toward the right side of the periodic table below oxygen, are the chalcogens, or “ore-forming” elements. The chalcogens that occur naturally, including sulfur, selenium and tellurium, are all somehow involved in biological processes. Molecules containing sulfur, like the antioxidant glutathione, play a central role in redox regulation, the balance between oxidation and reduction that is essential for maintaining cellular health.

Recent studies have suggested that the heavier selenium and tellurium are active in biological redox systems as well, but the instability of molecules containing chains of different chalcogen atoms has made structural analysis difficult.

Traditional methods have largely relied on mass spectrometry, which cannot be used to directly observe molecular bonds. This limitation motivated a team of researchers at Kyoto University to develop a method that would allow them to more clearly observe chains of chalcogens. The paper is published in the journal ACS Measurement Science Au.

Firefox now has a free built-in VPN with 50GB monthly data limit

Mozilla released Firefox 149 with added privacy protection through a built-in VPN tool offering up to 50GB of monthly traffic.

The feature uses a secure proxy server to route only traffic from the browser, unlike the company’s commercial Mozilla VPN, which covers system-wide traffic.

“Whether you’re using public Wi-Fi while traveling, searching for sensitive health information, or shopping for something personal, this feature gives you a simple way to stay protected,” Mozilla says.

The Jellies That Evolved a Different Way To Keep Time

Developmental biologist Tsuyoshi Momose cultures a newly discovered species of jellyfish in a tank of circulating water. Scientists want to understand how these unusual jellies keep time.

The passage of the sun across the sky — dawn, day, dusk, night — drives the clock of life. Some species wake with the sun and sleep with the moon. Others do the opposite, and a few keep odd hours. These naturally driven, 24-hour biological cycles are known as circadian rhythms, and they do more than cue bedtime: They regulate hormones, metabolism, DNA repair, and more. When life falls out of sync, there can be dire consequences for health, reproduction, and survival.

Lacking watches, many species keep time using an internal system — a set of interacting genes and their protein products that effectively keeps track of a 24-hour period — that is calibrated by sunlight. This kind of circadian clock is widespread, found even in single-celled algae, which suggests that biological timekeeping evolved billions of years ago. Across animals, most species have the same genetic system, using genes known as CLOCK, BMAL1, and CRY, or recognizable homologues. This form of biological clock mechanism appears even in ancient lineages, including sponges and some jellyfish.

But is this the only way to do it? In a pea-size jelly off the coast of Japan, biologists are examining a different kind of timekeeping.

Lysosomal defects are emerging as a feature in multiple inflammatory diseases

Barbara J. Vilen & team now identify defective late endosomes and lysosomes (LELs) in patients with active lupus and show reduced LEL function promotes SLE through chronic PI3k activity and SHP-1/SHIP-1 defects:

The figure shows bone marrow-derived macrophages from lupus prone mice (MRL/lpr) have decreased recruitment of pSHIP-1Y1022 (green) to the plasma membrane, indicated by cholera toxin-stained lipid rafts (blue), compared with control mice (B6).

The Sound of Contamination: A Comprehensive Analysis of Endocrine Disruptors and Hazardous Additives in the Headphones

The ToxFree Life for All project analysed 81 headphone models (180 material samples) across Central Europe and online marketplaces like Temu and Shein. 100% of products contained hazardous substances, including bisphenols, phthalates, and flame retardants. While these products do not pose an acute or “imminent” danger, the cumulative and synergistic effects of chronic exposure to these chemical classes pose a long-term risk to public health, therefore having a negative impact on sovereign consumer choice. The individual consumer has limited power to choose a safe product. Consumer protection is a systemic problem that cannot be solved by individual choice; it must be addressed at the institutional level.

Superconducting chip generates tunable terahertz waves for compact imaging

A tiny crystal chip which uses terahertz radiation to see clearly through a wide range of materials could find applications in health care, biological research, and security screening. Researchers from Scotland and Japan have developed a lightweight superconducting chip, which they say could unlock the full potential of terahertz imaging technologies and lead to the development of more powerful and portable devices.

The team’s paper, titled “Terahertz Imaging System with On-Chip Superconducting Josephson Plasma Emitters for Nondestructive Testing,” is published in IEEE Transactions on Applied Superconductivity.

Terahertz radiation lies between the microwave and infrared frequencies of the electromagnetic spectrum. It passes easily and harmlessly through a wide range of materials, and can be used to identify the characteristic “fingerprint” of molecules and biological materials as it does so, allowing them to be detected and analyzed.

A lysosome switch could reshape research on cancer and neurodegenerative disease

An international research team from Bielefeld University and the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) has uncovered a previously unknown regulatory mechanism in human cells. For the first time, they demonstrate how a key molecular switch regulates the cell’s “recycling centers.” The findings, published in Nature Communications, provide important insights into the understanding of cancer and neurodegenerative diseases.

Lysosomes are the control centers for the metabolism of cells and tissues, including the brain. They break down defective proteins and other macromolecules into their basic building blocks. At the same time, they determine whether a cell grows or switches into an energy-saving mode. In doing so, they play a key role in health and disease.

A research team led by Prof. Dr. Markus Damme of Bielefeld University and Prof. Volker Haucke, Director of the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP), has now jointly elucidated a key mechanism underlying this regulation.

Cost-Effectiveness of Adjuvant Immunotherapy in Cancer Treatments: A Systematic Review

Adjuvant immunotherapy is increasingly integrated into cancer care to reduce recurrence and improve survival. However, its high cost raises critical concerns regarding affordability and economic value across diverse health system contexts.

This review outlines health gains and economic value, and identifies where future research, pricing reform, or prioritization are needed to support evidence-informed policymaking and sustainable use of immunotherapy in cancer treatment pathways.

Question Is adjuvant immunotherapy cost-effective across cancer types?

Findings This systematic review including 69 economic evaluations (2015−2025) found that adjuvant checkpoint inhibitors, usually single-agent, were associated with higher quality-adjusted life-year/life-year gains and were determined to be cost-effective by 40 studies (58%), with the strongest signals in non−small cell lung cancer and melanoma, particularly in early-stage/high-risk populations, and for some combination regimens. Industry-funded studies more frequently reported cost-effective decisions and findings were sensitive to drug prices, model assumptions, and country-specific willingness-to-pay thresholds.

Meaning These findings suggest that adjuvant immunotherapy can offer good value for money in selected high-risk settings; decisions should be indication-specific, aligned with local health technology assessment thresholds, and supported by price negotiation or managed-entry agreements.
