- Disinfection byproducts (DBPs) are harmful chemicals that form when disinfectants react with natural organic matter and other precursors during water treatment and distribution. Over the past 50 years, more than 6,300 DBPs have been identified, many of which pose significant risks to human health and the environment.
- It is now possible to obtain three-dimensional, high-resolution images of enzyme activity in tissue samples or whole organs—thanks to probe molecules that anchor fluorescent dyes within tissue as they are activated by enzymes. The organ being mapped is made transparent by a clearing process.
- The interaction between growth and the active migration of cells plays a crucial role in the spatial mixing of growing cell colonies. This connection was discovered by scientists from the Department of Living Matter Physics at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS). Their results, published in Communications Physics, provide new approaches to understanding the dynamics of bacterial colonies and tumors.
- A fiber sensor inspired by the shape of DNA, developed by researchers at Shinshu University, introduces a new design for more durable, flexible fiber sensors in wearables. Traditional fiber sensors have electrodes at both ends, which often fail under repeated movement when placed on body joints.
- The NASA New Horizons spacecraft's extensive observations of Lyman-alpha emissions have resulted in the first-ever map from the galaxy at this important ultraviolet wavelength, providing a new look at the galactic region surrounding our solar system. The findings are described in a new study authored by the SwRI-led New Horizons team.
- A new straightforward way to make an injectable gel capable of releasing multiple drugs at specific speeds improves scalability and access to the technique, according to a University of Michigan study.
- Earth's atmosphere is much more sensitive to ripples of radiation from the sun than scientists previously believed, new research by Queen's University Belfast has found.
- The summer of 2024 was the warmest in 2,000 years in the Lapland region of northern Finland, Norway and Sweden, driven by climate change, the Finnish Meteorological Institute told AFP on Monday.
- Humans are known to make mental associations between various real-world stimuli and concepts, including colors. For example, red and orange are typically associated with words such as "hot" or "warm," blue with "cool" or "cold," and white with "clean."
- Nanomaterials are the future of modern technology. From powering batteries to improving clean energy systems and efficient catalysts, nanomaterials are everywhere. Their unique properties often arise from the precise arrangements of their atoms.
- One longstanding problem has sidelined life-saving drugs, stalled next-generation batteries, and kept archaeologists from identifying the origins of ancient artifacts.
- A research group led by Prof. Chen Liang at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences has designed a high-entropy electrocatalyst that achieves efficient production of hydrogen and valuable glycerol chemicals. The study was published in Nature Nanotechnology.
- Researchers, students and science-lovers across the world now have access to the design of the globally significant SABRE South dark matter experiment in the lead up to its installation in the Stawell Underground Physics Laboratory.
- In a development that could reshape the future of microelectronics, optics, and biomedicine, researchers from Jinan University, in collaboration with the Institute of Chemistry at the Chinese Academy of Sciences, have unveiled a new nanoprinting technology that simultaneously achieves unprecedented resolution and efficiency.
- Scientists have discovered a new type of immune defense in E. coli bacteria that turns viral infection machinery against the virus itself. Named after the Chinese military strategist Kongming—who famously used enemy weapons to defeat them—the system reveals a novel immune signaling pathway. This discovery could inform the development of future biotech tools and phage therapy as an alternative to antibiotics.
- Some things just go together in your belly: peanut butter and jelly, salt and pepper, bacteria and bacteria-eating viruses. For the bacterial species that inhabit your gut, there's a frenzy of viruses called bacteriophages that naturally infect them. Although they co-evolved with bacteria, phages get far less glory. They're harder to classify and so deeply entangled with the bacteria they target that scientists struggle to understand what functions they serve.
- Many atomic nuclei have a magnetic field similar to that of Earth. However, directly at the surface of a heavy nucleus such as lead or bismuth, it is trillions of times stronger than Earth's field and more comparable to that of a neutron star. Whether we understand the behavior of an electron in such strong fields is still an open question.
- What if counteracting mercury contamination in waterways could be as simple as adding selenium? That proposition has gained traction among some scientists and governments, but new research from Cornell and the U.S. Geological Survey (USGS) suggests the idea is likely too good to be true.
- A new economics study shows the potential for an ancient process to develop new domestic demand for rice and offset declining exports.
- Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), Chinese astronomers have discovered a new millisecond pulsar. The newfound pulsar, designated PSR J2129-1210O, was missed by previous searches as its spin period is close to the harmonics of the known pulsar PSR J2129+1210A.
