Two DNA defense systems behind resilience of 7th cholera pandemic
Cholera is caused by the bacterium Vibrio cholerae, a waterborne pathogen that infects the gut of humans through contaminated water and food. When ingested, V. cholerae colonizes the gut's inner surface, causing a watery diarrhea, that if left untr.....»»
A blueprint for mapping melting ice sheets: Open-source tool can help make radar systems at a fraction of the cost
Researchers in the Stanford Radio Glaciology lab use radio waves to understand rapidly changing ice sheets and their contributions to global sea-level rise. This technique has revealed groundwater beneath Greenland, the long-term impacts of extreme m.....»»

Monash University research has found that campus-wide lockdowns at universities based in Northern China during the COVID-19 pandemic impacted university students' value of trust, honesty, and creativity—behavioral traits that are crucial for positi.....»»
EPA lead ruling unlikely to resolve water contamination issues in LA public housing
Days after the administrator of the U.S. Environmental Protection Agency visited a Los Angeles public housing project with lead-contaminated water, the agency ordered drinking water systems nationwide to replace every lead pipe within 10 years......»»
SpaceX prevails over ULA, wins military launch contracts worth $733 million
SpaceX and ULA were eligible to compete for eight launches, and SpaceX won them all. The US Space Force's Space Systems Command announced Friday it has ordered eight launches from.....»»
Team develops promising new form of antibiotic that makes bacterial cells self-destruct
To address the global threat of antibiotic resistance, scientists are on the hunt for new ways to sneak past a bacterial cell's defense system. Taking what they learned from a previous study on cancer, researchers from the University of Toronto (U of.....»»
North Carolina"s hurricane damage is not just destroyed homes, but contaminated water systems, experts say
Hurricane Helene brought death and destruction to North Carolina, with the western part of the state in particular seeing entire towns and homes washed away......»»
How to spot AI deepfakes that spread election misinformation
Generative AI systems, such as ChatGPT, are trained on large datasets to create written, visual or audio content in response to prompts. When fed real images, some algorithms can produce fake photos and videos known as deepfakes......»»

Can NZ"s supply chain build enough resilience and sustainability to survive the next global crisis?
New Zealand is highly reliant on trade—particularly on maritime routes, which are lifelines for exports and imports. Key sectors such as agriculture, construction, and wholesale and retail trade depend heavily on this global network......»»
Single-molecule imaging reveals aberrant DNA-binding dynamics of cancer-linked chromatin remodelers
Biophysical chemists from the National University of Singapore (NUS) have uncovered a previously hidden landscape that governs the intracellular organization and dynamics of SWI/SNF chromatin remodelers, an important class of protein complexes that c.....»»
New fabrication strategy enhances graphene aerogel sensitivity and durability for human-machine interfaces
In recent years, researchers have synthesized various new materials that could be used to develop more advanced robotic systems, devices and human-machine interfaces. These materials include graphene aerogels, ultralight, porous and graphene-based ma.....»»
Resolving biology"s dark matter: DNA barcoding reveals hidden insect diversity
There are millions of species on Earth that we still know nothing about. Researchers call these species "biological dark matter," but new methods can provide us with a better overview more quickly......»»
A method to switch between optical pulling and pushing forces by altering the shape of Fermi arcs in Weyl systems
Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects such as cells, bacteria, and viruses. This effect is.....»»
It’s increasingly unlikely that humans will fly around the Moon next year
It's not just Orion's heat shield; the mission's ground systems are running out of time. Don't book your tickets for the launch of NASA's Artemis II mission next year just yet. W.....»»
Discovery of key protein for biosynthesis of plant defense steroids could enhance pest control strategies
Researchers at the Max Planck Institute for Chemical Ecology have identified GAME15 as a key protein that regulates the biosynthesis of both steroidal glycoalkaloids and steroidal saponins in plants of the genus Solanum......»»
New benchmark helps solve the hardest quantum problems
From subatomic particles to complex molecules, quantum systems hold the key to understanding how the universe works. But there's a catch: when you try to model these systems, that complexity quickly spirals out of control—just imagine trying to pre.....»»
Incorporating effects of sea spray into models to improve hurricane intensity forecasting
Hurricanes are massive, complex systems that can span hundreds of miles as they swirl around the low pressure of the storm's eye. In such a complicated situation, predicting how powerful a hurricane will grow is a difficult undertaking......»»
DNA-binding C2H2 zinc finger proteins also regulate RNA processing, researchers discover
Researchers at the University of Toronto have shown that an important class of DNA-binding factors can also bind to RNA, regulating gene expression through various mechanisms. The study significantly expands our understanding of these proteins' funct.....»»
Environmental DNA and epidemics in wood frogs: Collaboration examines eDNA"s precision in population size estimation
Tracy Rittenhouse, associate professor of natural resources and the environment in UConn's College of Agriculture, Health and Natural Resources (CAHNR), was doing an experiment to study ranavirus epidemics in wood frogs. When Meghan Parsley, then a P.....»»
Protein signaling pathway provides insights into cell migration and cancer metastasis
The innate immune response is the body's first line of defense against infection, and a successful immune defense takes a village: a combination of physical barriers, chemical attacks, and an army of specialized white blood cells. But maintaining and.....»»
