Phys.org / An ancient civilization of millions once flourished in the Amazon
New research conducted using airborne laser scanning reveals that a multicultural civilization that flourished in southwestern Amazonia between 600 BCE and 850 CE was home to millions of people. Spanning roughly 183,000 square ...
Medical Xpress / The first 72 hours: Hospital routines may undermine breastfeeding
An evidence review of international research suggests widespread misconceptions within the medical community about early milk production, pacifiers and breast pumps may be undermining breastfeeding success in the critical ...
Medical Xpress / Chromosome-protecting protein may help explain muscle repair and the rarity of muscle cancers
A protein best known for protecting the ends of chromosomes also helps muscle stem cells preserve their identity and repair damaged tissue, according to a new study from researchers at the Perelman School of Medicine at the ...
Phys.org / Newly discovered mechanism protects DNA during cell division
Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However, in some cases, chromosomes do not fully separate, leaving behind thin strands of DNA known as DNA bridges that connect ...
Phys.org / Cretaceous beetle fossil reveals early evolution of firefly sensory and signaling systems
Scientists have discovered a remarkably well-preserved 100-million-year-old beetle fossil that provides a rare glimpse into the evolution of the intricate sensory and communication systems used by fireflies and their relatives ...
Phys.org / Laying odds on the potential for Martian water near future landing zones
We know Mars has water ice in its polar regions, but astronauts (and their solar-powered equipment!) would much rather experience life closer to Mars' equator. As NASA looks toward landing humans on the red planet, the Planetary ...
Phys.org / Monkey friendships with dogs, deer and even pigs offer clues to the evolutionary origins of pet-keeping
Why do humans keep pets? A new international study suggests that some of the behavioral foundations of human-animal companionship may have much deeper evolutionary roots than previously thought.
Phys.org / Optimized magnetic pulses could cut memory switching energy by several orders of magnitude
Information and communication technologies (ICTs) driven by artificial intelligence (AI) are generating data at an unprecedented rate. Every internet search, AI-generated image, recommendation, scientific simulation and large ...
Phys.org / Rainfall across the US is increasingly coming from farther away
Before rain falls, the moisture that forms it may have traveled anywhere from just a few kilometers to hundreds or even thousands of kilometers away. It usually begins as water that evaporated from oceans, lakes, forests ...
Medical Xpress / A skill becomes automatic as the brain rewires itself to bypass its own bottleneck, new study suggests
Riding a bike, reading a book or folding laundry while watching TV can feel effortless, almost like your brain does it on autopilot. This ease comes from repetition, built through practicing the same task again and again. ...
Phys.org / Two Arctic charr populations evolved in less than a century, study finds
Evolution, the process through which animals and other living organisms change their inherited traits over time, typically unfolds slowly over thousands or even millions of years. Some species, however, can adapt at a faster ...
Medical Xpress / Scientists identify fructose as a surprise driver of cancer spread
A new study from The Wistar Institute has uncovered an unexpected link between fructose—a common dietary sugar—and the spread of an aggressive form of ovarian cancer. Published in Nature Aging, the study found that cancer ...
