AI tools help uncover enzyme mechanisms for lasso peptides
Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tes.....»»
X-Ray Imaging and Spectroscopy Mission unveils black hole and supernova remnant surroundings
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed the structure, motion and temperature of the material around a supermassive black hole and in a supernova remnant in unprecedented detail. Astronomers presented the first scientific resu.....»»
How a bacterial pathogen that causes dysentery manipulates molecular activity to assure its survival
Virginia Tech researchers have learned how bacteria manipulate molecules to infect the host organism. Daniel Capelluto and his research team have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysen.....»»
New material with wavy layers of atoms exhibits unusual superconducting properties
MIT physicists and colleagues have created a new material with unusual superconducting and metallic properties, thanks to wavy layers of atoms only billionths of a meter thick that repeat themselves over and over to create a macroscopic sample that c.....»»
Independent origins of frog glue and its role in predator evasion
Skin-secreted adhesives, or glues, are highly effective defense adaptations that have evolved recurrently in a small number of amphibians. From an ecological standpoint, this rapidly solidifying material—essentially, a sticky slime—encumbers the.....»»

Plant pathogen battle: A tomato protein"s dual role in defense and susceptibility
Tomatoes, a staple crop worldwide, are increasingly threatened by biotic stressors such as viruses, fungi, and bacteria, with the effects worsening under climate change. These challenges lead to reduced yields and compromised nutritional quality, hig.....»»
Bioengineers create new substrate to study wood-decomposing enzyme
Researchers want to transform the natural and abundant resource wood into useful materials, and central to that is a molecular machine found in fungi that decomposes the complex raw material into its basic components......»»
Template synthesis creates multilayered perovskites with unique ferroelectric behavior
A group of Nagoya University researchers in Japan has synthesized 4- and 5-layered versions of the important electrical material perovskite. Analyzing the mechanism of ferroelectricity in the material, they found it has a unique function: the materia.....»»
Harmless strain of E. coli bacteria may be able to prevent urinary tract infections
Researchers from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) and the College of Engineering are collaborating on a project that uses harmless strains of E. coli bacteria to disrupt the bacteria responsible for urinary.....»»
Scientists identify 18 bacterial strains to treat antibiotic-resistant gut infections
Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enteroba.....»»
Tiny robots and AI algorithms could help to craft material solutions for cleaner environments
Many human activities release pollutants into the air, water and soil. These harmful chemicals threaten the health of both people and the ecosystem. According to the World Health Organization, air pollution causes an estimated 4.2 million deaths annu.....»»
Do bacteria age?
Any organism that lives, grows and reproduces must also age. People often think of aging in the physical sense—gray hair, slowed movements and wrinkles—but aging fundamentally occurs on a molecular level, inside of cells......»»
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 nanotechnology, addressing no.....»»
The popular Eve Light Switch now supports Matter, no longer requires a hub
The Eve Light Switch with Matter brings added functionality to the popular device, and it can even be controlled without a hub now......»»
Soil pH drives microbial community composition: Study shows how bacteria work together to thrive in difficult conditions
Though a founding concept of ecology suggests that the physical environment determines where organisms can survive, modern scientists have suspected there is more to the story of how microbial communities form in the soil......»»
Printed engines propel the next industrial revolution
In the fall of 2023, NASA hot fire tested an aluminum 3D printed rocket engine nozzle. Aluminum is not typically used for 3D printing because the process causes it to crack, and its low melting point makes it a challenging material for rocket engines.....»»
Multifunctional phosphor developed for white LED lighting and optical thermometry
In the realm of lighting and temperature measurement, advancements in material science are paving the way for significant improvements in technology and safety. Traditional methods, which combine yellow phosphors with blue chips in LEDs, have limitat.....»»
Evidence of “snowball Earth” found in ancient rocks
An outcrop in Scotland has material from when the Earth went into a deep freeze. Enlarge / Artist's conception of the state of the Earth during its global glaciations. (credit: NASA) Earth has gone through many geologic.....»»
How bacteria actively use passive physics to make biofilms
When we think about bacteria, we may imagine single cells swimming in solution. However, similarly to humans, bacterial cells often socialize, using surfaces to coalesce into complex heterogeneous communities called biofilms. Within a group, bacteria.....»»
