Phys.org / How dogs evolved differently across the globe to match human traits
We call them "man's best friend," and the evidence supports it. Dogs have been found buried alongside humans in graves dating back 14,000 years. They appear in ancient art from every continent, and they feature in the mythology, ...
Medical Xpress / Smokers still largely unaware of heart disease risks
An international study has found that despite two decades of global tobacco control efforts, the message still is not getting through to enough smokers that smoking and secondhand smoke cause heart attacks and strokes.
Phys.org / DNA repair enzymes favor specific sequences, shaping mutation patterns in the human genome
When a wound does not heal properly, it leaves a scar. Similarly, mutations—which are permanent changes to genetic code—are often the result of damaged DNA that has not been properly repaired. Mutations can impede the function ...
Medical Xpress / Alzheimer's protein patterns vary across populations, biomarker study finds
Blood biomarkers may make it possible to detect changes seen in Alzheimer's disease without advanced brain imaging or cerebrospinal fluid tests. At the same time, much of the research behind today's biomarkers has been conducted ...
Phys.org / Oak leaves harbor distinct microbial worlds on their opposite surfaces
A single leaf may look like a simple patch of green, but to the microscopic life that inhabits it, it is a vast landscape divided into different worlds.
Phys.org / New species of mountain horned dragon identified in Thailand's high-altitude forests
Scientists have described a new species of lizard from the high mountain forests of western Thailand and have given it a name straight out of an American fantasy drama television series: Acanthosaura syrax, named after Syrax, ...
Phys.org / Journalism is key to combating bad practices in science
Watchdog science journalism has become a fundamental tool to counter scientific malpractice, such as publication fraud, abuse and political and corporate manipulation of science. A study by the Universitat Autònoma de Barcelona ...
Phys.org / Tiny particles defy action-reaction symmetry to stay in motion
From schools of fish and flocks of birds to microscopic synthetic particles, many systems in nature and the laboratory consist of individual units or agents that move by consuming energy. These systems are known as active ...
Phys.org / Consistency-based rewards could build lasting cooperation better than punishing free-riders
A vaccine only protects a whole community if enough people get it, including those who would stay safe anyway once their neighbors are covered. The same tension runs through climate action and social movements: The shared ...
Phys.org / Illegal fishing captures up to 15% of global marine wild catch, analysis finds
Industrial-scale illegal fishing continues to undermine ocean sustainability, coastal livelihoods and global seafood markets—despite decades of regulation and recent advances in surveillance technology, according to new University ...
Medical Xpress / Poorer people suffer greater declines in physical function as they age
In England and Canada, socioeconomic inequalities are associated with differences in how people age, with less wealthy people showing reduced mobility and function compared with their wealthier peers, according to a study ...
Phys.org / DNA origami nanosyringe actively transports molecules into synthetic cells
Transporting molecules across biological membranes is essential for life. In nature, this can occur through passive transport, known as diffusion. "Biological systems often use mechanical motion to accomplish tasks that cannot ...
