SARS-CoV-2 goes "underground" to spread from cell to cell
The virus that causes COVID-19 has adopted some stealth moves to stay alive and kicking, and one secret to its success is hiding from the immune system by spreading through cell-to-cell transmission, a new study has found......»»
Research on how gut bacteria breaks down dietary fiber could lead to helpful new probiotics
There are trillions of bacteria in the human gut microbiome. When we eat fruits and vegetables, some of these bacteria break down the dietary fiber and provide us with metabolites, small molecules our body can use for energy or cell repair......»»
Warming lakes and rivers may spread fish pathogens
Michigan's rivers and lakes were once cold enough that fish were protected from some infection-causing parasites. As the Great Lakes ecosystem warms, a Michigan State University researcher is investigating new pathogens that may become relevant to th.....»»
When ribosomes go rogue
Unusual variations in the cellular protein factory can skew development, help cancer spread, and more. But ribosome variety may also play biological roles, scientists say. In the.....»»
Live-cell imaging under centrifugation: New method measures the forces that keep the nuclei of living cells centered
Using two specialized microscopes invented at the Marine Biological Laboratory (MBL), a team of researchers from Japan and the MBL have developed a new method to measure the forces that keep the nucleus centered within a living cell. The experiments.....»»

An elegant switch regulates production of protein variants during cell division
Our cells contain thousands of proteins that have gone largely undetected and unstudied until recent years: these are variants of known proteins, which cells can make when their protein-building machinery interacts differently with the same stretch o.....»»
A multi-level breakthrough in optical computing—a faster, more efficient, and robust memory cell
For the first time, an international cadre of electrical engineers has developed a new method for photonic in-memory computing that could make optical computing a reality in the near future......»»
De-extinction company provides a progress report on thylacine efforts
Stem cell editing, complete genome, and cane toad resistance mark necessary steps. Colossal, the company founded to try to restore the mammoth to the Arctic tundra, has also deci.....»»
Researcher finds special proteins are key when antibiotic resistance spreads
Antibiotic resistance is a growing public health problem globally. The problem is exacerbated by the fact that some bacteria that have become resistant to antibiotics have the ability to spread that resistance to other bacteria via secretion systems......»»
Creating a simplified form of life: Scientists build modules for a synthetic cell
It is one of the most fundamental questions in science: how can lifeless molecules come together to form a living cell? Bert Poolman, Professor of Biochemistry at the University of Groningen, has been working on this problem for over 20 years. He aim.....»»
"Nano-weapon" discovery boosts fight against antibiotic-resistant hospital superbugs
Researchers have discovered how a bacteria found in hospitals uses "nano-weapons" to enable their spread, unlocking new clues in the fight against antibiotic-resistant superbugs......»»
How Cells Resist the Pressure of the Deep Sea
Cell membranes from comb jellies reveal a new kind of adaptation to the deep sea: curvy lipids that conform to an ideal shape under pressure......»»
Invasive flathead catfish impacting Susquehanna"s food chain, researchers find
Flathead catfish—native to the Mississippi River basin—were first detected in the Susquehanna River in Pennsylvania in 2002, according to the U.S. Geological Survey. In the two decades since then, the invasive species has spread throughout the ri.....»»
Q&A: Experts discuss the beaver, a controversial mammal
When an endangered species succeeds in repopulating its former habitat, the immediate reaction is one of joy. In the long term, however, its spread is often associated with conflict. One example is the beaver, a keystone species. Other keystone speci.....»»
An ill kitten in Nebraska sparked efforts to stamp out the spread of rabies
The 2023 illness and death in Nebraska of a stray kitten infected with rabies set off a large-scale effort to discover how the feline became infected in the first place......»»
Team achieves successful reproduction of hematopoietic stem cell developmental process in an in vitro culture system
Researchers at Kumamoto University have achieved a notable advancement in stem cell biology by reproducing the developmental process of hematopoietic stem cells (HSCs) in vitro. This culture system not only enhances our understanding of how HSCs deve.....»»
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.....»»
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......»»
Focus on making the sure bets so you can win today
Those bets include the most profitable (and increasingly efficient) gasoline-powered vehicles, proven battery-cell chemistries for electric vehicles and the driver-assist technology that more than 90 percent of new vehicles already have......»»
