Phys.org / Shorter front-leg strides can be an early warning sign of dementia in senior dogs
Scientists have shown that the stride length of the front legs (but not the hind legs) of senior and geriatric dogs decreases as their cognitive performance worsens. In contrast, chronological age itself was a poor predictor ...
Phys.org / New findings challenge idea that human bodies simply got bigger and bigger over time in a steady line
The biggest jump in body size among our ancestors happened around 2–2.5 million years ago, with the appearance of Homo rudolfensis or Homo erectus/ergaster, rather than gradually across the whole human family tree.
Tech Xplore / Digital barriers make visitors of Dutch websites stumble
Despite European legislation, many commercial websites still fall short when it comes to meeting the WCAG accessibility standard, Dante Göbbels has found. Göbbels investigated the barriers website visitors encounter, including ...
Medical Xpress / Mediterranean-inspired diet with added methionine extends healthy lifespan in mice
A plant- and fish-based, low-protein diet paired with small amounts of an amino acid commonly found in eggs, meat and dairy increased healthy lifespan and decreased frailty and fat mass in mice, according to a new USC study ...
Phys.org / Scientists create optical skyrmions using a two-century-old light phenomenon
Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the Poisson spot to create stable patterns of light called optical skyrmions, which are tiny, swirling ...
Phys.org / Students' climate model of deadly July 4 Texas flooding suggests sea surface temperatures actually reduced rainfall
Last fall, the 12 students in the Jackson School of Geosciences' GEO 347G "Climate System Modeling" class set out to understand something that hit close to home: What were the climatological factors that made the July 4, ...
Phys.org / Synthetic DNA toolkit expands scientists' ability to recognize genetic targets
A new method for recognizing and targeting DNA that dramatically expands the range of genetic sequences scientists can identify has been developed by experts at the University of Portsmouth. Published this week in Nature ...
Medical Xpress / Healthy gut microbes in 6-week-old infants linked to lower risk of malaria during first year of life
In a small study in the Democratic Republic of Congo, 6-week-old infants with healthy gut microbiomes were less likely to contract malaria in their first year of life. While the study is preliminary, it suggests the possibility ...
Medical Xpress / AI-aided 'master key' vaccine may block entire virus families, not single strains
Known by acronyms that need no explanation, viruses like COVID, SARS and Ebola conjure images of medics in protective suits and spark fear in populations worldwide.
Phys.org / Contagious cancer likely crossed an ocean, triggering severe outbreak in Pacific Northwest clams
Researchers have identified a severe outbreak of a rare contagious cancer in soft-shell clams in Washington state's Puget Sound and found evidence that the disease was recently introduced to the Pacific Northwest from Atlantic ...
Tech Xplore / AI and physics draw a blueprint for better hydrogen storage materials
Hydrogen can become a clever way to store renewable energy and power fuel cells—but this introduces the problem of what can store this hydrogen, in turn. Metal hydrides—solids that absorb hydrogen into their crystal structures—are ...
