TB antibiotic activity impacted by cell pH
Researchers at the Francis Crick Institute have shown that an antibiotic used to treat tuberculosis (TB) is affected by pH levels in the environment the bacteria has infected......»»
Live-cell imaging under centrifugation: New method measure 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......»»
Climate change projected to deplete food sources of endangered whale sharks
As part of her Ph.D. research at The University of Queensland, lead investigator Dr. Samantha Reynolds, now a Research Fellow from Murdoch University's Harry Butler Institute, used three future climate change scenarios from CMIP6 climate models to in.....»»
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......»»
Climate change to alter seasonal outdoor activity patterns in US
It can be hard to connect a certain amount of average global warming with one's everyday experience, so researchers at MIT have devised a different approach to quantifying the direct impact of climate change......»»
Scientists uncover how transcription drives motion within the genome
A team of scientists has discovered surprising connections among gene activity, genome packing, and genome-wide motions, revealing aspects of the genome's organization that directly affect gene regulation and expression......»»
Satellite-derived data on artificial light at night indicate rapidly increasing industrial activities in the Arctic
More than 800,000 km2 of the Arctic were affected by human activity in 2013, according to an analysis of satellite-derived data on artificial light at night. On average, 85% of the light-polluted areas are due to industrial activities rather than urb.....»»
Island arcs study reveals ancient connections between ocean chemistry and volcanic rocks
Bringing a novel approach to a classic problem, researchers have revealed how changes in ocean chemistry over the past 2 billion years have left an imprint on volcanic rocks formed in island arcs. Island arcs, which arise from volcanic activity along.....»»
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.....»»
New study reveals the effects of lockdowns in shaping socioeconomic behaviors
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.....»»
"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......»»
Chemical trick activates antibiotic directly at the pathogen
Colistin is a last-resort antibiotic that is usually only used for severe infections with resistant bacteria. This is due to its severe kidney-damaging side effects, which occur in about 30% of treated patients. A research team at the Helmholtz Cente.....»»
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......»»
Leveraging skyscraper architecture: New design enhances porosity and structural stability for metal-organic frameworks
The Burj Khalifa, the tallest building in the world, employs advanced construction techniques designed to withstand wind, seismic activity, and its own massive weight. Among these techniques is the "Meta Column System," which plays a pivotal role by.....»»
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.....»»
