Muscular strength and mortality in women ages 63 to 99

JAMA Network Open

2026-02-13

(Press-News.org) About The Study: In this study of ambulatory older women, greater muscular strength was associated with lower mortality even when controlling for accelerometer-measured physical activity and sedentary time, walking speed, and systemic inflammation. These findings suggest that assessing strength and promoting its maintenance are instrumental for optimal aging.

Adolescent and young adult requests for medication abortion through online telemedicine

2026-02-13

About The Study: Prior research finds abortion restrictions are associated with increased demand for telehealth medication abortion. However, whether this trend extended to adolescents was previously unknown, a population facing the unique legal burden of mandatory parental involvement, in addition to gestation bans. This study found that post-Dobbs increases in requests were highest among young adults, especially in states with restrictive abortion laws, and among adolescents, in states with gestational bans and parental consent and notification requirements.

Researchers want a better whiff of plant-based proteins

2026-02-13

COLUMBUS, Ohio – Off-putting smells can make even the healthiest of foods unpalatable. In a new study, researchers have developed a way to remove unpleasant aromas from plant-based proteins to make them smell more appealing. They did so by designing a two-step fermentation process to counter the odors that typically form during cultivation and extraction. The study’s results showed that their approach could remove between 95 to 99% of key smells, significantly outperforming one-stage fermentation ...

Pioneering a new generation of lithium battery cathode materials

2026-02-13

As the global electric vehicle (EV) market and renewable energy sector continue to expand rapidly, demand for advanced lithium-ion battery technology continues to grow. A research team from City University of Hong Kong (CityUHK) has been awarded funding under the "RAISe+ Scheme" to address the long-standing voltage decay issue associated with lithium-rich cathode materials. This groundbreaking research aims to introduce a new range of battery materials that offer enhanced energy density, extended lifespan and reduced costs. The ...

A Pitt-Johnstown professor found syntax in the warbling duets of wild parrots

2026-02-13

With a few minutes of searching, anyone can find videos online of chatty birds: macaws talk to their keepers, cockatoos sing to the camera, corvids mimic the jarring sounds of construction sites. Research has shown that some birds can understand and use words in context — so, when Polly speaks up from inside her cage, she may really want a cracker — but scientists know far less about how birds use their vocal abilities in the wild. Christine Dahlin, professor of biology at the University ...

Cleaner solar manufacturing could cut global emissions by eight billion tonnes

2026-02-13

Manufacturing next-generation solar panels could cut global carbon emissions by up to 8.2 billion tonnes by 2035, finds a new international study by researchers from the University of Warwick and Northumbria, Birmingham, and Oxford Universities. Solar panels, known scientifically as photovoltaics (PV), convert sunlight directly into electricity and are central to global decarbonisation. But as countries race to deploy solar at multi-terawatt scale, the carbon footprint of manufacturing these devices is coming under increasing scrutiny. At the same time, the industry is rapidly shifting from the current industry-standard ...

Safety and efficacy of stereoelectroencephalography-guided resection and responsive neurostimulation in drug-resistant temporal lobe epilepsy

2026-02-13

Temporal lobe epilepsy (TLE) is the most common form of focal epilepsy, affecting a significant proportion of patients who develop drug-resistant epilepsy. Surgical interventions, particularly stereoelectroencephalography (SEEG)-guided temporal lobe resection (TLR) and SEEG-guided responsive neurostimulation (RNS), have emerged as pivotal treatment options. This systematic review aims to compare the efficacy, safety, and quality of life (QoL) outcomes associated with these two interventions in adults with drug-resistant TLE. The review followed the PRISMA 2020 ...

Assessing safety and gender-based variations in cardiac pacemakers and related devices

2026-02-13

Background and objectives Cardiac pacemaker implantation is a primary therapy for various arrhythmic disorders; however, safety concerns persist in India. This study aimed to evaluate two-year safety outcomes of cardiac pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization therapy devices in a tertiary care setting. Methods In this prospective cohort study, data collection was conducted over a one-year enrolment period (February 2023 to January 2024), encompassing patient demographics, pacemaker implantation details, indications, and comorbidities. Patients were prospectively followed for a total of two years from enrolment—during the ...

New study reveals how a key receptor tells apart two nearly identical drug molecules

2026-02-13

G-protein-coupled receptors (GPCRs) are one of the largest families of cell surface proteins in the human body that recognize hormones, neurotransmitters, and drugs. These receptors regulate a wide range of physiological processes and are the targets of more than 30% of currently marketed drugs. The histamine H1 receptor (H1R) is one such GPCR subtype that plays a key role in mediating allergic reactions, inflammation, vascular permeability, airway constriction, wakefulness, and cognitive functions in the human body. While antihistamines primarily target H1R, current drugs can exhibit limited therapeutic efficacy, prompting researchers to look at H1R ligands from new perspectives. Recently, ...

Parkinson’s disease triggers a hidden shift in how the body produces energy

2026-02-13

Weight loss is a well-recognized but poorly understood non-motor feature of Parkinson’s disease (PD). Many patients progressively lose weight as the disease advances, often alongside worsening motor symptoms and quality of life. Until now, it was unclear whether this reflected muscle loss, poor nutrition, or deeper metabolic changes. New research shows that PD-related weight loss is driven mainly by a selective loss of body fat, while muscle mass is largely preserved, and is accompanied by a fundamental shift in how the body produces energy. Although PD is classically viewed as a neurological disorder, increasing evidence points to widespread ...

Eleven genetic variants affect gut microbiome

2026-02-13

In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do there. Only two genetic regions were previously known. Some of the new genetic variants can be linked to an increased risk of gluten intolerance, haemorrhoids and cardiovascular diseases. The community of bacteria living in our gut, or gut microbiome, has become a hot research area in recent years because of its great significance for health and disease. However, the extent ...
