New ultrathin lens focuses light into an optical needle

Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused over a long distance. Combining this lens, which is about 7 microns thick, with optical coherence tomography (OCT) could allow imaging that reaches deeper

Baseline tool could separate alien life signals from geology on ocean worlds

When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, scientists can be misled because certain geological processes can produce chemical signat

Isotope probing shows soil is packed with dormant viruses lying in wait

A single gram of soil contains between 10 million and 1 billion viruses. Most of those viruses do not infect plants, animals or people, but they do target bacteria and other microbes. Because of their influence on microbial communities, viruses can affect nutrient cycling and soi

Magnetic octupole model captures domain-wall motion in noncollinear antiferromagnets

Researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have developed the first magnetic multipole-based micromagnetic model for antiferromagnets. Published in Applied Physics Reviews, their generalized framework provides a theoretical

Saturn-ring-like laser emission from chiral polymeric microspheres

Controlling light within microscopic spaces is crucial for next-generation optical devices such as photonic integrated circuits and localized sensors. Microspheres formed of luminescent π-conjugated polymers act as optical resonators that confine and amplify light via whispering

Making the 'invisible' visible: How high-speed movies could change the way scientists stud

High-speed movies of microscopic worms may sound like a dull night at the cinema, but this advanced imaging capability could help scientists better understand how diseases begin and progress, track subtle changes in cells and study how the body responds to treatments.

Nanoplastics found in Antarctic soils for first time, suggesting long-range atmospheric tr

Microplastic contamination has been a much-discussed topic over the last several years, but contamination from even smaller plastic particles represents another pressing issue. Nanoplastics—defined as being under a micrometer in diameter—may pose an even higher ecological risk be

Is the state of nature fair? Researchers measure how biomass is distributed in microbial c

The distribution of income and growing inequality are central themes in public debate. Far less attention has been paid to how resources are distributed in ecological communities, in the so-called state of nature, without any social contract. Species abundance distributions have

Scientists used AI to crack one of water's biggest mysteries

Water’s odd behavior becomes even more dramatic when it is supercooled, but scientists have struggled to compare the many different ways of describing its microscopic structure. Researchers at the University of Osaka used an AI model trained on computer simulations to evaluate 16

South African fynbos soil delivers a new species of soil bacterium

Microbiologists from Stellenbosch University in South Africa have discovered a previously unknown bacterial genus within the phylum Acidobacteriota. It is the first genus from this phylum to be described from Southern Africa.

Decoding of one of nature's largest enzymes reveals electron flow behind biological methan

A research team at Marburg University has investigated one of the largest enzyme complexes found in nature to date and deciphered its remarkable structure. Under the supervision of Dr. Jan Schuller, Ph.D. student Sophia Paul from the Center for Synthetic Microbiology (SYNMIKRO) w
