How do cells react to micro- and nanoplastics?
The smaller plastic particles are, the more easily they can be taken up by cells. In addition, the shape, surface and chemical properties play an important role in answering the question of how the particles could affect human tissue. This conclusion.....»»
Silver nanoparticles and a new sensing method can fight back against antibiotic-resistant biofilms
From safeguarding our food supply to preventing hospital infections, the battle against antibiotic-resistant bacteria is a growing challenge. Some bacteria can form biofilms, thick aggregates of millions of individual cells surrounded by protective m.....»»
How to merge and unmerge cells in Microsoft Excel
Microsoft Excel has numerous powerful data analysis functions, but sometimes you need to do something simple like merge some cells. Here's how......»»
Biomolecules inside living cells can now be seen with infrared light thanks to new method

Uncovering the unique roles of Exportin-5 in RNA export within Drosophila cells
Eukaryotic cells are complex biological units, each with multiple membrane-bound compartments. These cells use specialized mechanisms to export biomolecules from their synthesis site to where they function......»»
How context-specific factors control gene activity
Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene regulation; essentially how and when genes are turned.....»»

Hijacking the command center of the cell: Nuclear parasites in deep-sea mussels
Most animals live in intimate relationships with bacteria. Some of these bacteria live inside the cells of their hosts, but only very few are able to live inside cell organelles (structures inside the cell, like organs in the body). One group of bact.....»»
AMD’s new CPU could silently replace the Ryzen 7 7800X3D
The latest addition to AMD's Zen 4 lineup is a Micro Center exclusive. Here's how it performs in benchmarks......»»
Decoding the language of cells with the power of proteomics
Hundreds of millions of years ago, single cells joined forces to become multicellular organisms. At the foundation of this multicellular world is the cell surface: the plasma membrane surrounding each cell, where individual units meet and communicate.....»»
BMW explains why it will sell hydrogen fuel cells in 2028
BMW sees hydrogen as complementary to battery EVs on a region-by-region basis. Enlarge / BMW has had some hydrogen fuel cell-powered iX5s in testing for a while, and for Art Basel 2024 this one got a new look courtesy of Es Devli.....»»
3D imaging allows researchers to observe degradation of micro- and nanoplastics with unprecedented detail
In a global first, University of Waterloo researchers have used 3D imaging technology to understand the fine details of microplastics, paving the way for more effective methods of plastic waste recycling......»»
Labs collaborate to enhance imaging tools for cell observation
Two labs at the University of Utah's Department of Chemistry joined forces to improve imaging tools that may soon enable scientists to better observe signaling in functioning cells and other molecular-scale processes central to life......»»
RNA editing plays critical role in fruit flies" sense of smell and social interactions
Imagine your DNA as a set of instructions or a recipe book that tells your body how to make everything it needs to function, from proteins to cells. Every time the body needs to build something, it reads these instructions. But sometimes, the body ca.....»»
Ultium Cells battery plant in Tenn. joins UAW
A majority of the 1,000 workers at the plant in Spring Hill, Tenn., operated by a joint venture between GM and LG, signed cards in favor of joining the union......»»
Preventing cell damage: Working principle of proton-activated chloride channels revealed
A research team led by Prof. Seo Byeong-Chang of the Department of Brain Sciences at DGIST has made the world's first discovery of how proton-activated chloride (PAC) channels—which play an important role in protecting cells in our bodies—work. P.....»»
Using fungal mycelium as the basis for sustainable products
Fungi have more to offer than meets the eye. Their thread-like cells, which grow extensively and out of sight underground like a network of roots, offer huge potential for producing sustainable, biodegradable materials. Researchers at the Fraunhofer.....»»
Micro-LED TVs: Are they still the next big thing?
Samsung and LG Micro-LED displays have plenty of potential, but this long-touted screen technology is still years away from being commercially viable......»»
3D bioprinting materials offer possibility for better bone and soft tissue repair
3D bioprinting is an advanced tissue engineering technique that builds complex tissues using bioactive substances like living cells and scaffolds. It provides personalized tissue repair solutions, reducing immune rejection by using patient-specific c.....»»
Cells use alternative splicing to regulate gene expression, research suggests
Alternative splicing is a genetic process where different segments of genes are removed, and the remaining pieces are joined together during transcription to messenger RNA (mRNA). This mechanism increases the diversity of proteins that can be generat.....»»
Saturday Citations: Corn sweat! Nanoplastics! Plus: Massive objects in your area are dragging spacetime
It's the last day of August, which means that in the Northern Hemisphere, tomorrow will be 50 degrees and cloudy; conditions are expected to be hot and humid south of the equator. In science news this week, we reported on nanoplastic contamination, s.....»»
