Phys.org / Cannabis essential oils unlock how camphor repels mosquitoes
From summer evenings to global disease prevention, mosquito repellents are a daily defense for billions of people, yet until now, scientists didn't fully understand how mosquitoes themselves perceive these "keep away" signals. ...
Phys.org / Mate choice: How social trends influence mate diversity
Whether people follow a general trend when choosing a partner or consciously decide against it has a noticeable impact on the diversity of phenotypes to choose from. This is shown by a new study by the University of Würzburg.
Phys.org / Shorter early-life telomere length could predict survival in Arctic seabirds
A study published in Ecological and Evolutionary Physiology reveals a surprising link between cellular aging markers and survival in black-legged kittiwakes (members of the gull family). In the work titled "Who's coming home? ...
Phys.org / Ice Age erosion may explain Appalachians' smoother northern peaks
Hike north on the Appalachian Trail and the scenery slowly transforms. Rugged, steep ridgelines in Tennessee and Virginia soften into the broad summits and smooth peaks of Pennsylvania and New Jersey. According to new research ...
Phys.org / When smaller means better: How device scaling enhances memory performance
Shrinking ferroelectric tunnel junctions can significantly boost their performance in memory devices, as reported by researchers from Science Tokyo. The team fabricated nanoscale junctions directly on silicon substrates and ...
Phys.org / Nutrient-driven 'death fronts' may explain why some antibiotics fail outside the lab
Antibiotics are medical marvels that have transformed once deadly bacterial infections into manageable conditions. But with a rise in antibiotic resistance that renders existing treatments ineffective, new agents are urgently ...
Phys.org / How studying yeast in the gut could lead to new, better drugs
A new study sheds light on the behavior of yeast cells in the gut, paving the way for new lines of yeast that more efficiently produce therapeutic drugs tailored to address specific diseases. The research is published in ...
Phys.org / How the color of a theater affects sound perception
Live music can engage more than just one sense, despite it being an auditory medium. Lighting and visual effects can enhance the listening experience, but it is unclear if they can also affect the impression of the sound. ...
Phys.org / Decision-making nudges can improve racial equity in tenure decisions
After years of research, teaching, and service, a faculty member's tenure and future in academia hinge on the evaluations of their peers—senior faculty who serve on promotion and tenure committees. These evaluations can ...
Phys.org / Marine plastic pollution alters octopus predator-prey encounters, study shows
More than 350,000 chemicals are used worldwide, and many find their way into the ocean through plastic pollution. As plastics accumulate in coastal waters, they continuously leach bioactive additives that can interfere with ...
Phys.org / Americans reveal deepening split between self and country
American reports of individual well-being have remained relatively stable over decades, but confidence in the nation has sharply declined. James N. Druckman and colleagues analyzed long-term survey data from two projects: ...
Phys.org / Methane's missing emissions: The underestimated impact of small sources
Methane is a potent greenhouse gas, with an impact estimated at 80 times that of CO₂. Although efforts are being made to reduce the contribution of big polluters to methane in Japan, new research from Osaka Metropolitan ...
