Phys.org / A supermassive black hole erupted in X-rays, and its radio jets followed 300 days later
By combining roughly two decades of observations from NASA's Swift X-ray Telescope with radio monitoring, astronomers have caught a supermassive black hole at the heart of the Perseus Cluster suddenly flaring in X-rays, and ...
Phys.org / Resin-mounted wallaby teeth reveal rare 1,200-year-old ornaments in Queensland
While sorting through animal bones in a rock shelter in Queensland, Australia, archaeologists came across a tooth where something was "not quite right." Stuck to the tip of its root was a blackish-brown ball of glue-like ...
Phys.org / Switching gravity on and off leaves particles behind, mathematical model finds
Hawking radiation causes black holes to eventually evaporate. This is because particle pairs are spontaneously created near the event horizon (the position of the last ray of light that can escape the black hole's gravitational ...
Phys.org / MeerKAT directly detects faint hydrogen signal from the distant universe
Astronomers from the University of Manchester and the University of the Western Cape have directly detected an extremely faint radio signal from hydrogen gas billions of light-years away, opening a powerful new way to map ...
Phys.org / LEDs let archaeologists see the past in a new light
An archaeological excavation is a little like eating a layered cake: Once you have removed a layer, you cannot put it back. The problem becomes even trickier if two layers look almost exactly the same. Researchers from Aarhus ...
Phys.org / Saturn encounter may have set distant centaur on path to becoming a comet
More than 3 billion miles (4.8 billion kilometers) from Earth, an ancient icy object is slowly awakening. As it drifts inward through the solar system, the frozen body known as Centaur 450P/LONEOS has begun releasing gas ...
Phys.org / In tune with nature: Human speech follows a rhythm that is also found in the animal kingdom
The temporal structure of speech rhythms resembles that of the communication signals of numerous animal species. This is shown by a study conducted by a research team from the Leibniz Center for General Linguistics (ZAS) ...
Phys.org / Old-growth tropical forests bear lasting legacy of ancient Maya civilization
Rainforests in Central America that have remained largely untouched by modern human activities could bear the invisible imprint of ancient Maya civilizations. New research has found that forest structure in Belize, such as ...
Phys.org / First measurement of low-energy solar neutrinos scattering off electrons
Every second, tens of billions of neutrinos produced by nuclear fusion in the sun pass through every square centimeter of Earth—and through our bodies—almost without interacting. Although they are among the most abundant ...
Phys.org / Food innovation in your kitchen: Giving peas, beans and lentils a surprisingly meat-like bite
Separating things and then putting them back together is a common principle in industrial food production. Agricultural raw materials are broken down into their individual constituents, such as proteins, starches and fats, ...
Phys.org / Firelight may have sparked human storytelling by extending social hours
New research from the University of St Andrews has developed a novel hypothesis of how firelight was critical to the evolution of sophisticated storytelling.
Phys.org / Single amino acid swap expands nanoparticle vaccine approach to influenza viruses
Influenza viruses constantly shapeshift to evade recognition by the immune system. This shapeshifting occurs in critical proteins like hemagglutinin (HA), which controls how the virus attaches to human cells before entering ...
