Phys.org / Scientists uncover recurrent patterns within chaotic quantum behavior
Many complex quantum systems rapidly lose the recognizable patterns of their initial states as their components interact. To describe patterns of regular and chaotic motion in specific systems, physicists can construct a ...
Phys.org / New saber-toothed predator from Argentina suggests its lineage survived longer than believed
In 2014, members of a local museum found fragments of an ancient fossil dating to the end of the Pliocene or early Pleistocene epoch in a seaside cliff on the Argentine pampas. They belonged to a large predator, but the only ...
Phys.org / Ancient DNA evidence narrows down when people first reached the Americas
One of the unresolved mysteries about the history of the Americas is when the first people arrived. Despite extensive debate centering on genetic, archaeological and environmental evidence, there is still no consensus or ...
Phys.org / Tiny ancient black holes may live in a five-dimensional world
Primordial black holes (PBHs) don't exist as far as we know. But if they did, these hypothetical objects would have formed in the early universe rather than from dying stars, and they may even make up dark matter. That's ...
Phys.org / US-German trio wins medicine Nobel for work on optogenetics
The Nobel Prize in medicine was awarded Monday to U.S. psychiatrist and neurologist Karl Deisseroth and German scientists Peter Hegemann and Georg Nagel for their pioneering work in the neuroscience field of optogenetics.
Phys.org / Lightsaber-like plasma antenna uses laser-ionized air to transmit radio waves
Researchers have demonstrated a technique that uses a laser to produce a plasma beam antenna capable of transmitting radio waves. The article, "Laser-Induced-Plasma-Filament Antenna Transmitting 30 MHz VHF," is published ...
Phys.org / Astronomers catch a star slowly snacking on a brown dwarf, 300 light years away
Like Earth, most planetary bodies circle their star in stable, detached orbits. These companionable systems can suddenly change when a planet comes too close to its star. In such a close encounter, a star can pull the planet ...
Phys.org / The phoenix planet: Astronomers find a world reborn from its star's ashes
Astronomers have discovered the first example of a second-generation planet orbiting a white dwarf, a world that appears to have formed from the remains of the dead star it now orbits.
Phys.org / How rotting food in the kitchen and a whiff of vinegar led to a 'happy' agricultural accident
Rutgers scientists have identified natural repellents against an invasive blueberry pest, a discovery made accidentally when fruit flies invaded their laboratory.
Phys.org / Rare insect discovery reveals a new species from the dinosaur age
Some 99 million years ago, during the age of the dinosaurs, a tiny insect belonging to a species previously unknown to science became trapped in tree resin. The resin hardened and turned into amber, and the fossil preserved ...
Phys.org / A novel path to fusion ignition: Heat first, then add fuel
For more than 70 years, fusion energy researchers have used a particular equation to judge whether a plasma would stay hot and dense enough—for long enough—to reach a point where it could sustain itself without any more external ...
Phys.org / Electrical technique could help identify signs of life in space
The truth is out there—but identifying signs of life in space involves an intense search for biosignatures within our solar system and beyond. However, developing sensitive yet compact technologies capable of detection has ...
