For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory instruments called spectrometers. ...

A long-standing mystery about how wild bats navigate complex environments in complete darkness with remarkable precision, has been solved in a new University of Bristol-led study. The findings are published in Proceedings ...

A team of scientists announced Tuesday they have developed new deep-sea landers specifically to test their contentious discovery that metallic rocks at the bottom of the ocean are producing "dark oxygen".

For social animals, encounters between rival groups can often lead to conflict. While some species avoid this by maintaining fixed territories, others, like the feral horses, live in a "multilevel society" where multiple ...

Researchers from the South Pole Telescope project team looked deep into the center of the Milky Way, discovering powerful, surprising bursts of light from two accreting white dwarf systems.

A new unified theory connects two fundamental domains of modern quantum physics: It joins two opposite views of how a single exotic particle behaves in a many-body system, namely as a mobile or static impurity among a large ...

The ocean is continuously ventilated when surface waters sink and transport, for example, oxygen and carbon to greater depths. The efficiency of this process can be estimated using the so-called water age, which describes ...

Light is a universal stimulus that influences all living things. Cycles of light and dark help set the biological clocks for organisms ranging from single-celled bacteria to human beings. Some bacteria use photosynthesis ...

Archaeologists working near Skipsea Castle in East Yorkshire say a series of rare discoveries is transforming understanding of life in the centuries before the Norman Conquest.

Researchers in the lab of Asst. Prof. Chibueze Amanchukwu at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) have spent three years looking for failure, scouring the academic literature for ...

Pūkeko use sound elements to create calls and combine them to create complex call sequences in order to expand the range of options for expressing themselves—these are the findings of an international team including Konstanz ...

A new analysis of air quality data from the past 70 years shows that Canada's record wildfire smoke in 2023 is part of a broader, continent-wide trend toward smokier skies across North America.
