When today’s older adults were growing up, urgent care centers and clinics inside retail stores didn’t exist. But most of them have now embraced these non-traditional sites for getting medical care, a new national poll finds.   In the past two years, 60% of people age 50 to 80 have visited an urgent care clinic, or a clinic based in a retail store, workplace or vehicle, according to new findings from the University of Michigan National Poll on Healthy Aging.   Urgent care clinics were the most ...

A team at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) has made a breakthrough discovery in the understanding of cardiac arrhythmias by unraveling the complexities of Andersen-Tawil syndrome (ATS), an extremely rare inherited cardiac disorder. Led by Dr. José Jalife, head of the CNIC Cardiac Arrhythmia Group, the study demonstrates that a specific genetic mutation (C122Y) in the Kir2.1 potassium channel alters the function not only of Kir2.1 but also of the main cardiac sodium channel NaV1.5, thus establishing a direct link with the life-threatening arrhythmias associated with ATS1. The study, published in the journal Circulation Research, reveals that ...

A team of researchers at Nagoya University in Japan has discovered that aldehydes are metabolic byproducts associated with premature aging. Published in Nature Cell Biology, their findings reveal insights into premature aging diseases and potential strategies to combat aging in healthy individuals such as controlling exposure to aldehyde-inducing substances including alcohol, pollution, and smoke.  A person's health can be harmed by aldehydes. However, the group’s findings suggest these detrimental effects also include aging. The team who made this discovery included Yasuyoshi Oka, Yuka Nakazawa, Mayuko Shimada, and Tomoo Ogi of Nagoya University.  “DNA ...

Chasing ever-higher qubit counts in near-term quantum computers constantly demands new feats of engineering. Among the troublesome hurdles of this scaling-up race is refining how qubits are measured. Devices called parametric amplifiers are traditionally used to do these measurements. But as the name suggests, the device amplifies weak signals picked up from the qubits to conduct the readout, which causes unwanted noise and can lead to decoherence of the qubits if not protected by additional large components. More importantly, the bulky size of the amplification chain becomes technically challenging to work around as qubit counts increase ...

Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth – and it could help assess which other planets can develop life, ranging from plants to animals and humans. The study, published today in Nature Geoscience and led by a researcher at the University of Bristol, reveals for the first time how the build up of carbon-rich rocks has accelerated oxygen production and its release into the atmosphere. Until now the exact nature of how the atmosphere became oxygen-rich has long eluded scientists and generated conflicting explanations. As carbon dioxide is steadily ...

Tokyo, Japan – The idea of growing a functioning human brain-like tissues in a dish has always sounded pretty far-fetched, even to researchers in the field. Towards the future goal, a Japanese and French research team has developed a technique for connecting lab-grown brain-mimicking tissue in a way that resembles circuits in our brain. It is challenging to study exact mechanisms of the brain development and functions. Animal studies are limited by differences between species in brain structure and function, and brain cells grown in the lab tend to lack the characteristic ...

New research in FEBS Letters indicates that treatment that boosts the effects of immune cells called stem cell memory T cells (TSCMs) may be a promising strategy for combating HBV. In the study, investigators identified TSCMs in patients with chronic HBV infection and analyzed their effects in a mouse model of HBV. After introducing TSCMs from patients ...

CLEVELAND, Ohio (April 10, 2024)—After the Women’s Health Initiative (WHI) in 2002, many women have resisted taking hormone therapy (HT), especially after age 65 years, because of fears of increased risks for various cancers and heart disease. A new study shows that those fears may be unfounded, depending on the type, route, and dose of HT. Results of the study are published online today in Menopause, the journal of The Menopause Society. Despite the conflicting results of a follow-up WHI study in 2004 and dozens of other studies since that time, a percentage of healthcare professionals and their middle-aged female patients continue to believe that ...

Adolescence is an important period of life for healthy growth. Malnutrition during this seminal period may have long-term adverse effects on health and development. In sub-Saharan Africa, there is a lack of nutrition programming for adolescents. Adolescent malnutrition represents an urgent issue in sub-Saharan Africa, which has a long history of undernutrition and a rising issue of overweight and obesity.  Findings from a new study suggest that a four-component school-based nutritional intervention package improved ...

Compared with Cd-based QDs, InP-based QDs have lower photoluminescence quantum yields (PL QYs) and broader full-width at half-maximum (FWHM). In particular, bare InP core has extremely low PL QY (＜1%) due to the ease of oxidation of their highly reactive surface even in insert reaction chambers. It has been reported that the defects from oxidative species are probably the reasons for the non-radiative recombination and poor PL QY of these materials. Over the last decade, extensive studies have been conducted to improve the optoelectronic properties of InP-based QDs for display and lighting applications, ...

Undertaking the majority of daily physical activity in the evening is linked to the greatest health benefits for people living with obesity, according to researchers from the University of Sydney, Australia who followed the trajectory of 30,000 people over almost 8 years. Using wearable device data to categorise participant’s physical activity by morning, afternoon or evening, the researchers uncovered that those who did the majority of their aerobic moderate to vigorous physical activity– the kind that raises our heartrate and gets us out of breath– between 6pm and midnight had the lowest risk of premature ...
