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 ...
Phys.org / Electron cooling tames highly charged ions in Penning trap for first time
Researchers at Technical University of Darmstadt and the GSI Helmholtz Center for Heavy Ion Research have succeeded for the first time in decelerating highly charged ions from the GSI accelerator to low energies and subsequently ...
Medical Xpress / Ancient mummy DNA provides scientific evidence that colonization brought smallpox to the Americas
Ancient mummy DNA recovered in Chile has yielded the firmest evidence yet that European colonization brought smallpox to the Americas.
Phys.org / Fossil footprints reveal body size and group dynamics of 1.4-million-year-old human relative
Ancient footprints preserved along the shores of Kenya's Lake Turkana are reshaping scientists' understanding of one of humanity's extinct relatives. A paper published in Proceedings of the National Academy of Sciences describes ...
Phys.org / Mom or not, caring for babies changes the brain
Freeman Hrabowski Scholar Bianca Jones Marlin studies how caregiving takes shape in the brain and how some biological adaptations are passed to the next generation.
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 / Deadly blooms offer a genetic blueprint for making hard-to-synthesize medicinal compounds
Two plants that cause neurotoxicity and paralysis in the tiniest doses are also known to counter pain, malaria, cancer and pests. For the first time, researchers discovered a way to recreate these powerful compounds in the ...
Medical Xpress / New study links exposure to fungicides and insecticides to changes in the age of menarche
Puberty is a process regulated by the endocrine system, and its timing can be altered by environmental factors. Several recent studies point to a trend toward earlier onset of puberty in girls, a phenomenon linked to a complex ...
Phys.org / How molecular tethers and asynchronous replication drive parasite proliferation
Malaria parasites proliferate in an unusual way. Rather than dividing into two daughter cells like human cells, they first amplify their genetic material tenfold, hundredfold or even thousandfold before simultaneously producing ...
Phys.org / Oil droplets remodel themselves, swallow their surroundings like living cells
NYU researchers have made microscopic oil droplets in water do something usually reserved for living cells: change shape in complex, controllable ways and even engulf their surroundings.
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 / Hiroshima blast debris reveals a previously unknown alloy
The Hiroshima blast on Aug. 6, 1945, was one of the most devastating events in human history. Like all nuclear detonations, it created fleeting moments of extreme heat, pressure, mixing and cooling. These conditions can briefly ...
