Phys.org / 10-thousand-year-old genomes from southern Africa change picture of human evolution
In southern Africa, a group of people lived in partial isolation for hundreds of thousands of years. This is shown in a new study based on analyses of the genomes of 28 people who lived between 10,200 and 150 years ago in ...
Phys.org / Free climbers discover remnants of ancient sea turtle stampede in Italy
Rocks have been found to hold many traces of Earth's ancient history, but usually geologists have to seek them out. Every once in a while, however, these imprints of times past are found by unsuspecting visitors. This occurred ...
Phys.org / Smart material instantly changes colors on demand for use in textiles and consumer products
Scientists have developed a revolutionary technique for creating colors that can change on command. These are structural colors that don't rely on dyes or pigments and can be used for display signage, adaptive camouflage ...
Phys.org / Interstellar object covered in 'icy volcanoes' could rewrite our understanding of how comets formed
Analysis of the second confirmed interstellar comet to visit our solar system suggests that the alien body could be covered in erupting icy, volcano-like structures called cryovolcanoes. Researchers also discovered that the ...
Phys.org / First evidence of lost-wax casting for silver in Bronze Age Western Europe uncovered
In a recent study, Dr. Linda Boutoille uncovered the first evidence of lost-wax casting of silver objects in Bronze Age Iberia and, to date, Western Europe. Published in the Oxford Journal of Archaeology, the study examines ...
Phys.org / KIC 5623923 is a faint eclipsing binary exhibiting Delta Scuti-type pulsations, observations find
Using NASA's Kepler space telescope, Chinese astronomers have observed a binary star system known as KIC 5623923. As a result, they found that the investigated system is a faint eclipsing binary experiencing Delta Scuti-type ...
Phys.org / Scientists rule out fourth neutrino in particle physics mystery
Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the particle many hoped would explain it.
Phys.org / The bacteria that won't wake up: NASA discovers new bacteria 'playing dead'
New research conducted on a NASA-discovered bacterium shows the microbe is capable of entering an extreme dormant state, essentially "playing dead" to survive in some of the cleanest environments on Earth.
Phys.org / Complex life developed nearly 1 billion years earlier than previously thought, study reveals
Complex life began to develop earlier, and over a longer span of time, than previously believed, a new study has revealed. The research sheds new light on the conditions needed for early organisms to evolve and challenges ...
Phys.org / Degraded peatlands emit nearly twice as much greenhouse gas as previously thought, study finds
For the first time, researchers have produced a detailed, high-resolution map of peatlands in the EU, showing that these areas emit twice as much greenhouse gases than previously thought. The research, led by eco-hydrologist ...
Phys.org / Golden Eagles in the West appear stable, but Nevada tells a different story
Golden Eagles (Aquila chrysaetos) have been protected in North America since 1962 and their populations in the West are considered stable. However, a new study published in the Journal of Raptor Research found that the Nevada ...
Phys.org / Simulations reveal how black holes generate intense light from infalling matter
Surprisingly, some of the universe's brightest objects are black holes. As scorching gas and dust flow around and into a black hole, they glow with fierce intensity across the light spectrum. Now, a team of computational ...
