Prevention and treatment campaigns are not adequately targeting the particular needs of the 50+ years age group. Indeed, between 2000 and 2016, the number of adults aged 50 years and older living with HIV in sub-Saharan Africa doubled. At present, their HIV prevalence is exceeding that of younger adults. By…
Researchers from Tokyo Metropolitan University have created a new way of telling “aged” human cells apart from younger ones using electric fields. While key markers have been found for these “senescent” cells, current methods require biochemical “labels” which are difficult to apply and affect the cells themselves, making them difficult…
For decades, quantum computers that perform calculations millions of times faster than conventional computers have remained a tantalizing yet distant goal. However, a new breakthrough in quantum physics may have just sped up the timeline. In an article published in PRX Quantum, researchers from the Graduate School of Engineering Science and…
In a follow up investigation into the multibillion dollar drug ticagrelor, The BMJ has uncovered fresh concerns, this time in key platelet studies used in its FDA approval.

New research that used blood markers to measure linoleic acid levels and their relation to cardiometabolic risk adds evidence that this omega-6 fatty acid may help to lower risks for heart disease and type 2 diabetes. The findings challenge claims that seed oils are harmful to cardiometabolic health. Linoleic acid,…
The idea seems futuristic: At ETH Zurich, various disciplines are working together to combine conventional materials with bacteria, algae and fungi. The common goal: to create living materials that acquire useful properties thanks to the metabolism of microorganisms — “such as the ability to bind CO2 from the air by…
Scientists at the USC Leonard Davis School of Gerontology have discovered a key connection between high levels of iron in the brain and increased cell damage in people who have both Down syndrome and Alzheimer’s disease. In the study, researchers found that the brains of people diagnosed with Down syndrome…
Plants and trees extend their roots into the earth in order to draw nutrients and water from the soil — however, these roots are thought to decline as they move deeper underground. But a new study by a multi-institutional team of scientists shows that many plants develop a second, deeper…
To reduce greenhouse gas emissions and combat climate change, the world urgently needs clean and renewable energy sources. Hydrogen is one such clean energy source that has zero carbon content and stores much more energy by weight than gasoline. One promising method to produce hydrogen is electrochemical water-splitting, a process…
The deep ocean can often look like a real-life snow globe. As organic particles from plant and animal matter on the surface sink downward, they combine with dust and other material to create “marine snow,” a beautiful display of ocean weather that plays a crucial role in cycling carbon and…
For more than a century, a patch of cold water south of Greenland has resisted the Atlantic Ocean’s overall warming, fueling debate amongst scientists. A new study identifies the cause as the long-term weakening of a major ocean circulation system. Researchers from the University of California, Riverside show that only…
A diabetes medication that lowers brain fluid pressure has cut monthly migraine days by more than half, according to a new study presented today at the European Academy of Neurology (EAN) Congress 2025.1 Researchers at the Headache Center of the University of Naples “Federico II” gave the glucagon-like peptide-1 (GLP-1)…
MIT researchers have designed a compact, low-power receiver for 5G-compatible smart devices that is about 30 times more resilient to a certain type of interference than some traditional wireless receivers. The low-cost receiver would be ideal for battery-powered internet of things (IoT) devices like environmental sensors, smart thermostats, or other…
Colorado State University researchers have published a paper in Science that describes a new and more efficient light-based process for transforming fossil fuels into useful modern chemicals. In it, they report that their organic photoredox catalysis system is effective even at room temperatures. That advantage could lower energy demands around…
Two species of worms have retained remarkably similar patterns in the way they switch their genes on and off despite having split from a common ancestor 20 million years ago, a new study finds. The findings appear in the June 19 issue of the journal Science. “It was just remarkable,…
UBC researchers are proposing a solution to a key hurdle in quantum networking: a device that can “translate” microwave to optical signals and vice versa. The technology could serve as a universal translator for quantum computers — enabling them to talk to each other over long distances and converting up…
Viruses are entirely dependent on their hosts to reproduce. They ransack living cells for parts and energy and hijack the host’s cellular machinery to make new copies of themselves. Herpes simplex virus-1 (HSV-1), it turns out, also redecorates, according to a new study in Nature Communications. Researchers at the Center…
Peatlands across the Arctic are expanding as the climate warms, new research shows. Scientists used satellite data, drones and on-the-ground observations to assess the edges of existing peatlands (waterlogged ecosystems that store vast amounts of carbon). The study – led by the University of Exeter – found peatlands in the…
Intense, short-lived summer downpours are expected to become both more frequent and more intense across Alpine regions as the climate warms. In a new study, scientists from the University of Lausanne (UNIL) and the University of Padova analyzed data from nearly 300 mountain weather stations and found that a 2°C…
For many, fitness trackers have become indispensable tools for monitoring how many calories they’ve burned in a day. But for those living with obesity, who are known to exhibit differences in walking gait, speed, energy burned and more, these devices often inaccurately measure activity — until now. h For many,…
Self-esteem scores more than doubled within one year of weight-loss surgery, according to a new study* presented today at the American Society for Metabolic and Bariatric Surgery (ASMBS) 2025 Annual Scientific Meeting. Researchers from Geisinger Medical Center found that after bariatric surgery self-esteem scores rose to 77.5 from 33.6 –…
Intermittent fasting diets appear to have similar benefits to traditional calorie-restricted diets for weight loss, suggests an analysis of trial evidence published by The BMJ on June 18. Alternate day fasting also demonstrates greater benefits compared with both calorie restriction and other intermittent fasting approaches, but the researchers say longer trials…
Researchers can now observe the phonon dynamics and wave propagation in self-assembly of nanomaterials with unusual properties that rarely exist in nature.
