A thermodynamic approach to gravity could explain cosmic acceleration without dark energy

Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general relativity. This framework describes gravity as the curvature of spacetime, the invisible four-dimensional fabric of the universe.

Megacluster of bacterial genes reveals four antibiotics that jointly starve rivals of biot

Researchers at McMaster University have discovered what they describe as a "megacluster" of genes in Streptomyces bacteria that produces four antibiotics that work together to stop rival bacteria.

Novel rice paddy approach aims to prevent toxic metals from tainting rice

In a perspective published in Nature Reviews Earth & Environment, Colorado State University researchers describe a management approach to prevent the uptake of arsenic, cadmium and mercury in rice grains to protect human health. They propose strategies that would change soil chem

Semiconductor quantum dots 'reawaken' predicted Rabi oscillations, boosting quantum contro

Physicists at Paderborn University have, for the first time, experimentally demonstrated the so-called "return" of Rabi oscillations in semiconductor quantum dots. The phenomenon, which was first predicted theoretically in 2007, describes the decrease in the emission intensity of

Peptide alternative to antibiotics could combat antimicrobial resistance crisis

A University of Alberta research team has designed a promising alternative for treating antimicrobial-resistant infections, a pressing global health issue. In a paper recently published in Cell Biomaterials, the team describes preclinical testing results for its human-derived pep

First ever dinosaur found in Antarctica described for science

The first dinosaur fossil found on the Antarctic continent has been described scientifically. The fossil, a vertebra, was found on a British Antarctic Survey (BAS) expedition in 1985 but has only recently been recognized as that of a dinosaur. The paper, "A titanosaurian sauropod

Mice actively seek better views to make visual decisions, virtual reality experiments show

Animals don't experience the world passively. A hawk tilts its head to track prey. A person leans forward to read a sign. Scientists call this "active sensing": moving the body to gather better information. A specific version of active sensing is infotaxis, which describes how an

World's first synthetic cell with a complete life cycle could revolutionize biological eng

While many of life's mysteries remain unsolved, every biologist can describe the basic processes performed by a living organism, including energy use, reproduction, growth and development. While these characteristics can be replicated in isolation in a lab, the idea of a complete

Beyond the dust: Families describe daily health challenges near the Salton Sea

A study examining air quality and respiratory health in communities surrounding the Salton Sea in Southern California shows how environmental conditions, poor housing quality and structural inequities combine to place children at greater risk for respiratory illness.

Quantum gravity tests may mistake ordinary spacetime for superposition

Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the behavior of the microscopic world, while Einstein's theory of gravity describes

Dynamic black holes may obey Hawking-style thermodynamics with an alternative entropy meas

Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, physicists have relied on complex equations from
