Cells" electric fields keep nanoparticles at bay, scientists confirm
The humble membranes that enclose our cells have a surprising superpower: They can push away nano-sized molecules that happen to approach them. A team including scientists at the National Institute of Standards and Technology (NIST) has figured out w.....»»
Protein from mosquitoes could help control dengue virus infection
NUS scientists have revealed the structure and function of a pupal cuticle protein found in the exoskeleton—a hard covering that supports and protects the bodies of some types of invertebrate animals, especially arthropods—of Aedes aegypti mosqui.....»»
Salt, microbes, acid and heat in food preservation
In an era of grocery stores and home refrigerators, it is easy to lose sight of the fact that, for most of history, people have been bound by the seasonality of food. This reality has long presented humanity with a conundrum: how to keep eating after.....»»
China"s medieval Tang dynasty had a surprising level of social mobility, new study finds
In studying social mobility in today's industrialized nations, researchers typically rely on data from the World Economic Forum or, in the United States, the General Social Survey. But examining the same phenomena from past centuries is a more daunti.....»»
New technique provides insight into how proteins involved in cellular processes communicate via extracellular vesicles
One way that cells communicate with one another is through the secretion and uptake of extracellular vesicles (EVs). EVs convey a multitude of cargoes, including proteins, lipids and nucleic acids. Their uptake affects the function of recipient cells.....»»
New study reveals impact of skin microorganisms on earthworm toxicity in polluted environments
In a study published in the journal Eco-Environment & Health, researchers from Zhejiang University revealed the crucial role of epidermal microorganisms in influencing earthworm toxicity under environmental stress, notably in conditions of nano zero-.....»»
Researchers unravel complex 3D structure of thick filaments in human heart
It's been estimated that over one lifetime, a heart will beat 2.5 to 3 billion times without stopping. Yet the mechanics of how the heart physically carries out this function flawlessly, without fail, minute after minute, remains poorly understood on.....»»
DNA construction leads to unexpected discovery of important cell function
Researchers at Karolinska Institutet in Sweden have used DNA origami, the art of folding DNA into desired structures, to show how an important cell receptor can be activated in a previously unknown way. The result opens new avenues for understanding.....»»
Scientists develop high-power optic fiber laser to power nano satellites
The use of lasers in space is a reality. Even though radio waves have been the backbone of space communications for ages, the demand to convey more data, in a faster way, made these lighter, more flexible, and more secure infrared rays (invisible to.....»»
Stem cell study throws our understanding of gene regulation for a loop
The blueprint for human life lies within the DNA in the nucleus of each of our cells. In human cells, around six and a half feet of this genetic material must be condensed to fit inside the nucleus. DNA condensation is not random. To function properl.....»»
Unraveling the role of supersulfides in regulating mitochondrial function and longevity
Supersulfides are gaining prominence for their occurrence as low-molecular-weight thiols or persulfidated cysteine residues, observed more frequently in both prokaryotic and eukaryotic cells. These compounds, which are characterized by sulfur–sulfu.....»»
Cryo-microscopy reveals nano-sized copy machine implicated in origin of life
How the intricate molecular machinery of life arose from simple beginnings has been a long-standing question. Several lines of evidence point towards a primordial "RNA world," where an "RNA copy machine" (a so-called replicase) started making copies.....»»
AI poisoning could turn open models into destructive “sleeper agents,” says Anthropic
Trained LLMs that seem normal can generate vulnerable code given different triggers. Enlarge (credit: Benj Edwards | Getty Images) Imagine downloading an open source AI language model, and all seems well at first, but it.....»»
First-Ever Biorobotic Heart Helps Scientists Study Cardiac Function
A model heart made from living tissue fused with robotic muscles could help researchers see how the organ works on the inside.....»»
Do former regulators improve the quality of audits?
In their auditing capacity, accounting firms, such as the "Big Four"—Deloitte, EY, KPMG and PWC—function as watchdogs for publicly traded companies. They're tasked with ensuring financial disclosures are accurate and above board. But who watches.....»»
Study views the city as a multi-layered system in cultural heritage management
The intense changes in our modern society and the associated challenges are constantly increasing, not least due to the meta-crisis of climate change. Yet our approach to cultural heritage is still strongly influenced by the narrative of preservation.....»»
Study shows effects of vegetation composition, warming and nitrogen deposition on peatland carbon sink function
Peatlands, which contain about one-third of the global soil carbon stock, are important carbon sinks. Their net carbon uptake is equivalent to ~1% of human fossil fuel emissions or 3%–10% of the current net sink of natural terrestrial ecosystems. H.....»»
Noninvasive technique reveals how cells" gene expression changes over time
Sequencing all of the RNA in a cell can reveal a great deal of information about that cell's function and what it is doing at a given point in time. However, the sequencing process destroys the cell, making it difficult to study ongoing changes in ge.....»»
