Phys.org / Archaeological digs in Amazon provide clues about Indigenous inhabitants before colonization
Paving roads in the Amazon rainforest has long brought deforestation that threatens the people who live there. The same roadwork, however, has also allowed archaeologists to get glimpses of the region's past long before Europeans ...
Phys.org / We think norms spread by imitation, but one deceptively simple rule tells a more human story
A paper appearing in Proceedings of the National Academy of Sciences offers a strikingly simple answer to a longstanding question: How do people learn and settle on shared social conventions, from everyday habits to workplace ...
Phys.org / Honeybees pass their math test, upending an animal intelligence debate
We've run the numbers and the verdict is in: Honeybees do have the ability to process numerical information. New research led by Monash University has now addressed recent international debate over whether bees are truly ...
Phys.org / What if humans could regrow tissue? New study moves science closer
For centuries, the inability to regrow lost body parts has been considered a defining limitation of humans and other mammals. While animals like salamanders can regenerate entire limbs, humans are left with scar tissue. But ...
Phys.org / What wild honey from the Philippine jungle reveals about biodiversity
In the Philippines, Indigenous communities have been harvesting wild honey for centuries. A new chemical analysis of this honey now provides insights into the biodiversity of the region. "And an additional reason to protect ...
Phys.org / Riding the quantum wave: Quasiparticles reveal a magneto-optical transport phenomenon
Excitons are being explored in materials science and information technology as a means of storing light. These luminous quasiparticles move through individual layers of quantum materials and can absorb and emit light with ...
Phys.org / Milky Way's 'little cousins' may hold clues about infant universe
Ultra-faint dwarf galaxies—tiny satellite galaxies orbiting the Milky Way—have long been seen as cosmic fossils. Now, a new study published today in Monthly Notices of the Royal Astronomical Society uses an unprecedented ...
Phys.org / Life's earliest proteins may have folded into complex shapes with far fewer amino acids
How did the earliest life on Earth build complex biological machinery with so few tools? A new study explores how the simplest building blocks of proteins—once limited to just half of today's amino acids—could still form ...
Phys.org / Did NASA's Curiosity rover find signs of ancient life on Mars? An astrobiologist explains how we determine 'life'
NASA's Curiosity rover has identified seven new organic compounds on the planet Mars, according to new research published in Nature Communications.
Phys.org / In Eastern Africa, the cradle of humankind is tearing apart
Eastern Africa's Turkana Rift is both a hotbed for fossil discoveries of our earliest ancestors and a literal hotbed of volcanic activity caused by shifting tectonic plates. Now researchers have found that Earth's underlying ...
Phys.org / Moon dust could stop being a nuisance and start reshaping how humans may build beyond Earth
As space agencies and private companies look toward a sustained human presence on the moon, a fundamental challenge centers on how to build strong, durable infrastructure without hauling every material from Earth. New research ...
Phys.org / How a sinking lithospheric root raised Mongolia's Hangay Mountains
Central Mongolia's Hangay Mountains rise more than four kilometers above sea level, forming a dramatic dome that shapes the region's climate. But for decades, geologists have been puzzled: What caused this massive mountain ...
