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.....»»
How Chlamydia pneumoniae bacteria use molecular mimicry to manipulate the host cell
Bacteria that cause diseases, so-called pathogens, develop various strategies to exploit human cells as hosts to their own advantage. A team of biologists from Heinrich Heine University Düsseldorf (HHU), together with medical professionals and exper.....»»
Cryo-electron microscopy provides new insights into the cell"s repair system
The membrane that surrounds cells in living organisms is extremely flexible and sensitive. How it protects itself from damage and renews itself is crucial for many life processes, and is not yet fully understood in detail. Scientists at Forschungszen.....»»
Nanopore technique shows transport mechanism of chaperone proteins at the single-molecule level
Proteins control most of the body's functions, and their malfunction can have severe consequences, such as neurodegenerative diseases or cancer. Therefore, cells have mechanisms in place to control protein quality......»»
Single-celled eukaryote employs unconventional cytoskeletal components for dynamic shape-shifting
Recently, a research group led by Prof. Miao Wei from the Institute of Hydrobiology (IHB) of the Chinese Academy of Sciences discovered that Lacrymaria cells utilize unconventional and novel components of the cytoskeleton to achieve their remarkable.....»»
Dead Cells follow-up Windblown already feels like a roguelike classic
Dead Cells follow-up Windblown is heading into early access later this month and it's already feeling spectacular......»»
Engineers create a chip-based tractor beam for biological particles
MIT researchers have developed a miniature, chip-based "tractor beam," like the one that captures the Millennium Falcon in the film "Star Wars," that could someday help biologists and clinicians study DNA, classify cells, and investigate the mechanis.....»»
Tesla plans four new batteries in 2026, including for robotaxi, The Information reports
Tesla plans four new batteries in 2026. Tesla sources most of its EV batteries from other companies, including Panasonic Energy and LG Energy but wants to ramp up production of its 4680 battery cells......»»
Scientists find plant-like behavior in human cells
A team of scientists from Monash University has solved the structure of a protein known as "LYCHOS," which can detect and regulate cell growth by sensing cholesterol levels in the body......»»
As the Advanced Photon Source upgrade nears completion, scientists anticipate experimental possibilities
In June, X-rays began to shine again at the U.S. Department of Energy's (DOE) Advanced Photon Source (APS), a facility where intense, directed X-ray light beams are used to inspect everything from materials for better solar cells and batteries to ant.....»»
These Record-Breaking New Solar Panels Produce 60 Percent More Electricity
Experimental cells that combine silicon with a material called perovskite have broken the efficiency record for converting solar energy—and could eventually supercharge how we get electricity......»»
First-ever artificial cell nuclei created in living egg from purified DNA injection
A research group is the first in the world to succeed in constructing artificial cell nuclei by injecting purified DNA solution instead of sperm into living mouse eggs. Their findings are published in the journal Genes to Cells......»»
Nanopillars create tiny openings in the nucleus without damaging cells
Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a technology that performs a similarly delicate task in living cells.....»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»

Elucidating the mechanism of cell division during plant self-healing
When the stem of a plant is injured, the surrounding cells proliferate to repair and fuse the damaged tissue, eventually restoring function. This self-healing property is utilized in grafting techniques to propagate fruit and vegetable plants......»»
Scientists identify structural basis of stitched-together protein complexes that recycle most proteins in cells
Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell's recycling process for obsolete and misshapen proteins—known as proteasomes—are formed......»»
Building better bone grafts: Nanofibrous scaffolds to activate two main collagen receptors in bone cells
Each year, about 2.2 million bone-grafting procedures are performed worldwide, the gold standard of care being autografting, which uses the patient's own bone for tooth implantation and to repair and reconstruct parts of the mouth, face and skull......»»
The 1963 Ford Cardinal—too radical for America at the time
Here's what happened when Ford tried to react to the Volkswagen Beetle. Enlarge / This was supposed to be Ford's answer to the VW Beetle, a small, light, efficient, front-wheel drive car called Cardinal. (credit: Ford).....»»
Scientists develop method to control timing of synthetic DNA droplet division
Many cellular functions in the human body are controlled by biological droplets called liquid-liquid phase separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside living cells but are not enclosed by membranes like.....»»
"Tamed" molecules for more sustainable catalysts: Chemists succeed in synthesizing a spectacular gallium compound
Catalysts play an important role in the manufacture of many products that we encounter in everyday life—for example in cars for exhaust gas purification or in the chemical industry in the production of fertilizers. Catalysts ensure that these react.....»»
