Phys.org / Why are some people mosquito magnets? Clues are emerging
Ever felt like mosquitoes bite you while ignoring everyone else? Scientists are now making progress in deciphering the complex chemical cocktail that makes particular people more enticing to these disease-spreading bloodsuckers.
Phys.org / Ancient iceberg scratches reveal reverse Great Lakes snowbelt
Buffalo's legendary snowfall totals are largely the result of one unlucky geographic reality: the city sits east of the Great Lakes instead of west. Anyone who has lived through a winter in Buffalo, Cleveland or any snowbelt ...
Medical Xpress / Is 'yo‑yo dieting' really harmful? New analysis challenges longstanding assumptions about weight cycling
Weight loss followed by weight regain, commonly known as "yo-yo dieting" or weight cycling, is often portrayed as harmful, even more damaging than remaining overweight. But a new comprehensive analysis published in The Lancet ...
Phys.org / New study provides rule of thumb to estimate land sustainability in river deltas
As densely populated coastal communities struggle to keep up with rising sea levels, new research reveals a way to predict how river deltas build land and protect coastal regions from encroaching oceans. This insight will ...
Phys.org / Bright blazar reveals 433-day optical quasi-periodic oscillation across nine years
By analyzing the data from the Whole Earth Blazar Telescope (WEBT), an international team of astronomers has discovered optical quasi-periodic oscillation (QPO) in a bright quasar known as 3C 454.3. It is so far one of the ...
Tech Xplore / Humans are bad at making complex decisions. AI can call them out
When a list of pros and cons won't cut it, a new decision-making tool developed by Cornell researchers can use artificial intelligence to help make difficult decisions. But there's a twist: Instead of checking AI's result, ...
Phys.org / How studying friendship has changed the way I understand my own loneliness
A few years ago, I had just moved into a house.
Phys.org / Ganymede's unique magnetic field may be powered by ongoing core formation—not a cooling core
Ganymede is not only Jupiter's largest moon, but also the largest in our solar system and one of the few that hosts a massive ice ocean. Adding to this planet-like moon's uniqueness is the fact that among the hundreds of ...
Tech Xplore / A single real-world data point may stop AI model collapse, analysis suggests
New work explaining the inner workings of artificial intelligence could provide a way around the threat of AI "model collapse," potentially averting growing numbers of AI hallucinations in the future.
Phys.org / New alien-life test could help Mars and Europa missions read organic molecules
For decades, the search for life beyond Earth has revolved around a key question: What molecules should scientists be looking for on other planets or moons? A new study, published in Nature Astronomy, suggests that the more ...
Phys.org / Warming climate favors shallower cyclones, challenging current risk assessments
As tropical cyclones (TCs) are among the most destructive natural hazards worldwide, understanding how TCs change under climate warming is of critical importance. While substantial progress has been made in projecting changes ...
Phys.org / Biodegradable sensors attached to plants detect pesticides in 3 minutes
Researchers at the São Carlos Institute of Physics at the University of São Paulo (IFSC-USP) in Brazil, led by Paulo Augusto Raymundo-Pereira, have created biodegradable, "wearable" sensors for plants to monitor their health, ...
