Phys.org / After 80 years, elusive molecules reveal how ozone starts turning plant emissions into haze
Scientists have directly observed a fleeting chemical reaction that creates a key ingredient in urban smog. The research offers insight into the earliest stages of pollution formation and could help improve air quality forecasting ...
Phys.org / Fossil-fuel carbon fingerprint reaches the deep North Atlantic
The use of fossil fuels alters both the concentration and the carbon isotope composition of carbon dioxide in the atmosphere. Since surface water exchanges carbon dioxide with the atmosphere, this also alters the isotopic ...
Phys.org / For Legionella bacteria, taking over a cell means playing by its rules
When it comes to invading healthy cells, Legionella bacteria rely on blending in rather than breaking in. New research from Van Andel Institute scientists demonstrates how a protein produced by Legionella mimics the behavior ...
Phys.org / Scientists unlock 'ancestral code' of banana family
Scientists have recently reconstructed the ancestral karyotype of the banana family, revealing how chromosome numbers decreased stepwise from 17 to 9–11 over evolutionary time.
Phys.org / Forty forest drought experiments reveal trees show little physiological acclimation
Forests support much of the world's biodiversity and play a vital role in regulating Earth's climate, but they are increasingly exposed to drought. To understand the potential consequences of drought, a key question is whether ...
Medical Xpress / Gut bacteria may communicate differently with the human body in patients with Parkinson's disease
A new study from the University of Oulu suggests that gut bacteria may send different biological signals in Parkinson's disease. The findings add to growing evidence that changes in the gut could be linked to Parkinson's ...
Phys.org / Using plutonium to probe the universe: Magneto‑ν experiment advances dark matter and neutrino research
Astronomers can't see dark matter directly, but they know it's there: Its gravity shapes galaxies and the large-scale structure of the cosmos. In an effort to uncover the composition of this hidden mass, a team at Lawrence ...
Tech Xplore / Simulated proving ground trains and assesses AI for actively controlling fluid dynamics
A platform for training and comparing machine learning models to actively reduce drag, improve lift, cut noise and manage heat has been launched by an international team that includes researchers at the University of Washington, ...
Medical Xpress / First-in-human pilot trial improves stem cell collection and delivery for sickle cell gene therapy
Patients with sickle cell disease are often hesitant to undergo transformative gene therapy—the current lengthy process requires multiple hospital visits to collect enough stem cells. Researchers from Boston Children's Hospital ...
Medical Xpress / People say they would not want to test embryos for traits like low IQ. But if given the information, they act on it
A study of more than 2,000 people in the United States and China finds that the line between medical and nonmedical traits, which underpins rules on embryo testing in most countries, does not match public preferences.
Phys.org / Congo Basin study reveals nuanced relationship between people and flooding
In the Lac Télé Community Reserve, a vast tropical peatland in Africa's Congo Basin that is home to about 20,000 people, the forces of climate change and globalization are hitting residents hard. The seasonal floods upon ...
Medical Xpress / We can eat bread several times a day—as long as it's whole grain, dietitian says
Bread is one of our staple foods, but these days it is also one of the most divisive: some people eat it with everything, while others see it only as a source of carbohydrates and fear it will make them gain weight. According ...
