Study suggests statistical 'noise' affects perceived evolutionary rates

For decades, researchers have observed that rates of evolution seem to accelerate over short time periods—say five million years versus fifty million years. This broad pattern has suggested that "younger" groups of organisms, ...

Low-noise amplifiers aboard the Arctic Weather Satellite

The Arctic Weather Satellite (AWS) of the European Space Agency (ESA) was sent on its journey to a polar orbit 600 km above the Earth on August 16, 2024. On board: four low-noise amplifiers (LNAs) from the Fraunhofer Institute ...

Study sheds light on trade-off between noise and power in nanoscale heat engines

Thanks to nanoscale devices as small as human cells, researchers can create groundbreaking material properties, leading to smaller, faster, and more energy-efficient electronics. However, to fully unlock the potential of ...

Paying attention to errors can improve fused remote monitoring of lakes, researchers say

Lakes can tip the scales from healthy to potential environmental hazard quickly when they become eutrophic. In this state, an abundance of nutrients accelerates algae growth, which then crowd the water's surface and block ...

Thanks to humans, Salish Sea waters are too noisy for resident orcas to hunt successfully

The Salish Sea—the inland coastal waters of Washington and British Columbia—is home to two unique populations of fish-eating orcas, the northern resident and the southern resident orcas. Human activity over much of the 20th ...

Fluctuating hydrodynamics theory could describe chaotic many-body systems, study suggests

Although systems consisting of many interacting small particles can be highly complex and chaotic, some can nonetheless be described using simple theories. Does this also pertain to the world of quantum physics?

AI helps distinguish dark matter from cosmic noise

Dark matter is the invisible force holding the universe together—or so we think. It makes up about 85% of all matter and around 27% of the universe's contents, but since we can't see it directly, we have to study its gravitational ...
