Sudden cardiac arrest among young competitive athletes before and during the COVID-19 pandemic
2025-02-24
About The Study: This cohort study found no increase in sudden cardiac arrest/sudden cardiac death in young competitive athletes in the U.S. during the COVID-19 pandemic, suggesting that reports asserting otherwise were overestimating the cardiovascular risk of COVID-19 infection, vaccination, and myocarditis. Many athlete cases shown in social media video montages occurred before the pandemic yet claimed COVID-19 infection or vaccination raised the risk of sudden cardiac arrest/sudden cardiac death.

Researchers find telemedicine may help reduce use of unnecessary health tests
2025-02-24
Low-value care—medical tests and procedures that provide little to no benefit to patients—contributes to excess medical spending and both direct and cascading harms to patients. A research team from Mass General Brigham and their collaborators have found that telemedicine may help to reduce the use of low-value tests. The work is published in JAMA Internal Medicine.
“In theory, widespread adoption of telemedicine post-pandemic may influence low-value testing—such as Pap smears and prostate cancer screenings in older adults, and imaging scans for straightforward cases of low back pain,” said lead author Ishani ...

Mega-iceberg from Antarctica on collision course with South Georgia: harbinger of things to come?
2025-02-24
It is no strange sight to see icebergs break off of the Antarctic ice cap and drift away, like the gigantic sheet of ice that is currently heading for the island of South Georgia. But climate change is making it happen more frequently, with ever-larger icebergs in the waters around Antarctica. Researchers from Utrecht University are studying the routes that icebergs followed during geological periods of rapid ice cap deterioration, such as the ends of ice ages. That provides crucial information about the effect of melting icebergs on the oceans, and its consequences for the future. In the process, ...
Beneath the bog: FAU awarded $1.3 million to track carbon and gas flow in peatlands
2025-02-24
Peatlands, a type of wetland found around the globe at all latitudes – from the Arctic to the tropics – are important ecosystems that store vast amounts of carbon. In fact, peatlands hold about one-third of the world’s soil carbon, despite covering only about 3% of the Earth’s land surface. When peatlands are disturbed or altered, they can release that carbon back into the atmosphere as greenhouse gases like methane. Peatlands are valuable ecosystems both for their biodiversity and for their role in regulating climate.

Scientists track evolution of pumice rafts after 2021 underwater eruption in Japan
2025-02-22
Tokyo, Japan – Researchers from Tokyo Metropolitan University have carried out an unprecedentedly detailed survey of pumice rafts in the aftermath of the 2021 Fukutoku-Oka-no-Ba volcanic eruption in Japan. Using samples from 213 different locations, they considered raft density, the size and roundness of individual pumice, and biological species attached. Their findings revealed three phases in the evolution of drift pumice, involving rounding, fragmentation, and the diversification of attached biological organisms over time.
It is said that 85% of volcanic eruptions happen underwater. While their cousins on land might seem more vivid, the effects of underwater eruptions can be just as ...
The future of geothermal for reliable clean energy
2025-02-21
Historically, access to geothermal energy has hinged on real estate’s famously three most important factors: location, location, and location. Because conventional geothermal power plants require hot, permeable rocks and plenty of underground fluid, use of the technology has been limited mostly to places with recent volcanism, such as Japan, New Zealand, the Philippines, Kenya, El Salvador, Iceland, and the western United States.
Over the past 50 years, however, techniques originally developed for oilfields and adapted for “enhanced geothermal systems” (EGS) have offered the promise ...

Scented wax melts may not be as safe for indoor air as initially thought, study finds
2025-02-21
As traditional candles burn, they can contribute to indoor air pollution by emitting volatile compounds and smoke, which may pose inhalation risks. Scented wax melts are often marketed as safer alternatives to candles because they’re flame- and smoke-free. But in a study in ACS’ Environmental Science & Technology Letters, researchers describe how aroma compounds released from the melted wax can react with ozone in indoor air to form potentially toxic particles.
Previous research has shown that scented wax melts emit more airborne scent compounds than traditional candles. The ...

Perovskite solar cells: Thermal stresses are the key to long-term stability
2025-02-21
Perovskite solar cells are highly efficient and low cost in production. However, they still lack stability over the decades under real weather conditions. An international research collaboration led by Prof. Antonio Abate has now published a perspective on this topic in the journal Nature Reviews Materials. They explored the effects of multiple thermal cycles on microstructures and interactions between different layers of perovskite solar cells. They conclude that thermal stress is the decisive factor in the degradation of metal-halide perovskites. Based on this, they derive the most promising strategies to increase the long-term stability of perovskite solar cells.
