Phys.org / How giant galaxies could form just 1.4 billion years after the Big Bang
The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international team led by Nikolaus Sulzenauer and Axel Weiß from the Max Planck Institute for Radio Astronomy ...
Phys.org / Mauled by a bear, 27,500 years ago: What a lavish teen burial reveals
A teenager's skeleton lay supine in a shallow pit on a bed of red ocher, his remains adorned with several ivory pendants, four perforated antler batons, mammoth ivory pendants, and a flint blade, his skull decorated with ...
Phys.org / Non-biologic processes don't fully explain Mars organics collected by Curiosity, researchers say
In a new study, researchers say that nonbiological sources they considered could not fully account for the abundance of organic compounds in a sample collected on Mars by NASA's Curiosity rover. The paper is published in ...
Phys.org / DNA-binding proteins from volcanic lakes could improve disease diagnosis
Scientists have uncovered new DNA-binding proteins from some of the most extreme environments on Earth and shown that they can improve rapid medical tests for infectious diseases. The work has been published in Nucleic Acids ...
Phys.org / The wild physics that keeps your body's electrical system flowing smoothly
Building on their pioneering 2018 research into how some of the body's cells, such as neurons and cardiac tissue, communicate via ions that flow through cellular channels, chemists at the University of Massachusetts Amherst ...
Phys.org / Bison hunters abandoned long-used site 1,100 years ago to adapt to changing climate, Great Plains study finds
On the Great Plains of North America, bison were hunted for thousands of years before populations collapsed to near extinction due to overexploitation in the late 1800s. But long before then, bison hunters used various strategies ...
Phys.org / Half of the world's coral reefs suffered major bleaching during the 2014–2017 global heat wave, estimates suggest
Benefits to society from coral reefs, including fisheries, tourism, coastal protection, pharmaceutical discovery and more, are estimated at about $9.8 trillion per year. For the first time, an international team led by Smithsonian ...
Phys.org / When heat flows backwards: A neat solution for hydrodynamic heat transport
When we think about heat traveling through a material, we typically picture diffusive transport, a process that transfers heat from high-temperature to low-temperature as particles and molecules bump into each other, losing ...
Dialog / How charges invert a long-standing empirical law in glass physics
If you've ever watched a glass blower at work, you've seen a material behaving in a very special way. As it cools, the viscosity of molten glass increases steadily but gradually, allowing it to be shaped without a mold. Physicists ...
Phys.org / Acoustic communication—an overlooked driver in boxfish evolution
A new international study reveals the unexpected importance of acoustic communication in the evolution of boxfishes. This discovery offers new perspectives on the role of acoustic communication in the evolutionary history ...
Phys.org / Where did that raindrop come from? Climate model ensemble captures worldwide water isotopes over 45 years
Water is made of hydrogen and oxygen, and sometimes these atoms are slightly heavier than usual. These heavier forms are called isotopes. As water evaporates or moves through the atmosphere, the amount of these isotopes changes ...
Phys.org / Noise pollution is affecting birds' reproduction, stress levels and more: The good news is we can fix it
New research led by the University of Michigan is painting a more comprehensive picture of how noise pollution is impacting birds around the world. "The major takeaway from this study is that anthropogenic noise affects many ...
