Phys.org / Male sperm whales produce loudest communication sounds ever measured in any mammal
Deep in the world's oceans, large male sperm whales emit slow, low-frequency clicks with the highest source levels of any animal communication sounds. These slow clicks are not the echolocation clicks the whales use to locate ...
Phys.org / Pluto's hazy atmosphere may be collapsing as it moves farther from the sun
Pluto is on an icy march away from the sun. In 2114, it will turn back, but until then, its elliptical orbit will carry it to colder and darker parts of the outer solar system. This is Pluto's first time entering the outer ...
Phys.org / Metal deposits reveal how ice ages reshaped oxygen levels across Earth's oceans
Earth's oceans repeatedly lost oxygen and produced metal deposits during the planet's deepest ice ages. An international team of researchers analyzed manganese and other chemical signatures preserved in more than 27,000 ancient ...
Phys.org / Mechanical shortcut' rapidly carries organic particles into the deep ocean
The processes that capture carbon from the atmosphere and store it on the seabed are crucial for climate balance. However, assessing these mechanisms is often complicated because it requires measurements ranging from the ...
Phys.org / Over 100 South American lakes could become climate-change early-warning observatories
More than 100 shallow lakes stretching over 1,000 kilometers (620 miles) along the Atlantic coast of southern Brazil and Uruguay could become one of the world's most important natural laboratories for understanding how climate ...
Phys.org / Humpback whales match song themes to dive phases, tags reveal
For male humpback whales, singing is serious business. Their haunting, complex songs can last for hours and travel for miles underwater, playing a central role in reproduction during the winter breeding season. But despite ...
Phys.org / Why we overestimate the positive impact of our actions on the climate
Why is recycling waste or switching off the lights sometimes perceived as more effective for the climate than giving up air travel? A team from the University of Geneva (UNIGE) surveyed nearly 3,000 people and identified ...
Phys.org / Cells of the same age can follow sharply different biological aging paths
New research reveals that cells of the same chronological age can follow dramatically different biological aging paths, offering new insights into cancer, neurodegeneration and the fundamental biology of aging. Rather than ...
Phys.org / Scientists watch, molecule by molecule, as cell helpers rescue problem proteins
University of Wollongong (UOW) scientists have uncovered, for the first time, exactly how two of the cell's "helper" proteins operate as a rescue crew for misfolded proteins, a discovery that sheds new light on the molecular ...
Phys.org / Underground fungal networks come into 3D view without disturbing plant roots
Symbioses between plants and fungi are essential for most plants. Fungal structures known as mycorrhizae extend the area from which plants can draw water and nutrients from the soil. In return, plants supply the fungi with ...
Phys.org / Four labs find experimental differences can undermine AI catalyst predictions
To turn abundant carbon dioxide into valuable fuel, we need a fast and efficient way to determine which catalysts work best over the longest time. AI models have the potential to help guide catalyst selection, but as with ...
Phys.org / Pixel patterns harness diffraction for faster, more accurate nanoscale 3D printing
Researchers at the George W. Woodruff School of Mechanical Engineering have developed a new approach to nanoscale 3D printing that improves both speed and fidelity, overcoming a challenge that has limited the technology's ...
