A study in Health Economics reveals that comprehensive state bans on flavored e-cigarettes may reduce vaping among young adults, but they can also lead to increased use of traditional cigarettes. Using information from national datasets and advanced statistical methods, researchers found evidence that young adults 18–24 years of age decrease their use of e-cigarettes by about 2–3 percentage points after state bans, while increasing traditional cigarette use by a similar amount. Because cigarettes are more dangerous to health than e-cigarettes, there appears to be a net negative effect on health for this age group. For youth ...

Research in Economic Inquiry reveals that Major League Baseball teams appear to manage player injuries differently depending on contract status, with players on temporary contracts missing significantly fewer games due to injury. This suggests that teams may invest less in the long-term health of non-permanent players. For the study, investigators analyzed 2009–2017 data, with 4,125 observations for 1,184 unique players, so that the average player had available data for approximately 3.5 years. The findings raise ...

Traditional polymers such as plastics are widely utilized for their chemical inertness and durability. However, these very properties make them non-degradable in nature and cause long-term environmental damage due to their persistence. In this light, biodegradable polymers that can be broken down by microbes have gained a lot of attention and scientists have turned towards cyclic ketene acetals (CKAs), a group of organic compounds containing carbon atoms and oxygen arranged in a ring-like structure, to develop biodegradable polymers. CKAs ...

SDE BOKER, Israel, September 3, 2025 — A groundbreaking study from researchers at Ben-Gurion University of the Negev reveals that desert soils can emit powerful greenhouse gases within minutes of being wetted—even in the absence of microbial life. Published by Dr. Isaac Yagle and Prof. Ilya Gelfand at BGU's Blaustein Institutes for Desert Research in Scientific Reports, the study challenges long-standing assumptions that soil microbes are solely responsible for post-rain “pulse emissions” of gases like carbon dioxide (CO₂), nitrous oxide (N₂O), and nitric oxide (NO). ...

Scientists studying ways of improving motion sickness have found that playing different types of music may help people recover more effectively. Using a specially calibrated driving simulator, they induced car sickness in participants and then played different types of music while they tried to recover. Soft and joyful music produced the best recovery effects, while sad music was less effective than doing nothing at all.   “Motion sickness significantly impairs the travel experience for many individuals, and existing pharmacological interventions often carry side-effects such as drowsiness,” explained Dr Qizong Yue of Southwest University, China, corresponding author ...

Experts have uncovered the earliest known example of a fish with extra teeth deep inside its mouth - a 310-million-year-old fossilised ray-finned fish that evolved a unique way of devouring prey. Platysomus parvulus had a unique way of eating never seen in ray-finned fish from that time – a ‘tongue bite’, using a special set of teeth on the floor and roof of the mouth to help it crush and chew tough food like shells or insects. Most fish today use their jaws to bite and chew, but some also have tongue bites, which work like a ...

Progress in life-saving treatment for opioid-use disorder with the medication has stalled in the past several years, according to a Rutgers Health study. However, researchers added that while some states were able to achieve substantial improvement, others lost ground.  Specifically, states that have expanded access to Medicaid insurance coverage since 2018 saw increases in prescriptions for opioid-use disorder treatment, according to the study, while states that haven’t ...

Duluth, MN - In the world’s cold and snowy regions, shorter and warmer winters are one of the most conspicuous consequences of climate change. For freshwater lakes, this means later freezing, earlier thawing, and thinner ice. A new study, published in Ecology Letters, shows that the ecological impacts of these winter changes may be most dramatic in high-latitude lakes. “The ecology of ice-covered lakes is a bit of a black box for lake scientists,” said Ted Ozersky, a University of Minnesota Duluth biologist who led the research. “For a long time, we assumed that nothing interesting happened under the ice, so few studies looked at what goes on in ...

It's hard to believe that there is anything positive that could come out of wildfires. They have devastated homes, taken lives, erased memories, leveled cities and destroyed our forests and wildlands. But a University of Delaware professor has found that there is something of value to be learned from what’s left behind in the remnants. The charred debris left in the wake of wildfires, such as those currently burning in Colorado, Canada and Arizona’s Grand Canyon National Park, is known as wildfire char. UD’s Pei Chiu, professor of civil, construction ...
