How blocking cell wall formation stops bacterial cell division
Researchers still do not understand exactly how antibiotics kill bacteria. However, this understanding is necessary to develop new antibiotics. And that is precisely what is urgently needed, because bacteria are currently showing more and more resist.....»»
Why is Elon Musk talking to Vladimir Putin, and what does it mean for SpaceX?
NASA chief says ties between SpaceX CEO and Putin should be investigated. In a blockbuster story published Friday morning, The Wall Street Journal reports that Elon Musk has been.....»»
Did some of Earth"s water come from the solar wind?
The source of Earth's water is an enduring mystery that extends to exoplanets and the notion of habitability. In broad terms, Earth's water was either part of the planet from the beginning of its formation in the solar nebula or delivered later, mayb.....»»
Bacterial pathogen must balance between colonizing airways and developing antibiotic tolerance, study reveals
Imagine trying to settle into a new home while constantly being attacked. That's what the bacterium Pseudomonas aeruginosa faces when it infects the lungs, and it can't both spread and protect itself from antibiotics at the same time......»»
Political polarization poses health risks, new analysis concludes
News coverage of the 2024 election season has often centered on how partisan division has affected our politics. But a new analysis shows that political polarization also poses significant health risks—by obstructing the implementation of legislati.....»»
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......»»
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.....»»

New technology illustrates bacterial "hibernation states"
Like hibernating bears, certain bacterial cells have the ability to shift into a "low-power" metabolic state in which they can stably survive without growing. This state is often seen in the context of antibiotic-resistant infections as bacteria form.....»»
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......»»
Google’s AI detection tool is now available for anyone to try
Google's DeepMind division announced Wednesday that is releasing its SynthID AI content authentication system for general public use......»»
Availability of parental leave may affect social norms on gender division of childcare
In research published in the British Journal of Social Psychology, investigators have examined the relationship between countries' parental leave policies and young adults' perceptions of social norms for the division of childcare duties between moth.....»»
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.....»»
Structural biology analysis of a Pseudomonas bacterial virus reveals a genome ejection motor
The viruses that infect bacteria are the most abundant biological entities on the planet. For example, a recent simple study of 92 showerheads and 36 toothbrushes from American bathrooms found more than 600 types of bacterial viruses, commonly called.....»»
Tesla faces questions on robotaxi service, $25,000 model and flat sales in Q3 earnings report
Wall Street analysts expect a drop in Tesla's third-quarter margins after it boosted incentives to juice sales of its aging core vehicles, the Model Y crossover and Model 3 sedan......»»
Discovery of new bacterial toxins could be key to fighting infections
Researchers have discovered a new group of bacterial toxins that can kill harmful bacteria and fungi, opening the door to potential new treatments for infections. These toxins, found in over 100,000 microbial genomes, can destroy the cells of bacteri.....»»
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.....»»
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......»»
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.....»»
