A poison helps us understand molecular hydrogen-producing biocatalysts
In nature, enzymes termed hydrogenases are capable of producing molecular hydrogen (H2). Special types of these biocatalysts, so-called [FeFe]-hydrogenases, are extremely efficient and therefore of interest for biobased hydrogen production. Although.....»»
Light microscopy study reveals molecular density changes during mitotic chromosome condensation
A team of scientists studying cell division developed a special light microscopy system and used it to analyze the molecular density of cellular environments. Their results provide a novel insight into mitotic chromosome condensation in living human.....»»
Maintaining company confidentiality simultaneously hurts and helps workers" well-being
A hush has fallen over the workplace. At tech startups and banks, in doctors' offices and law firms, workers are increasingly being asked to keep secrets. These aren't personal confidences but organizational secrets about clients, proprietary technol.....»»
Algorithm raises new questions about Cascadia earthquake record
The Cascadia subduction zone in the Pacific Northwest has a history of producing powerful and destructive earthquakes that have sunk forests and spawned tsunamis that reached all the way to the shores of Japan......»»
Discovery of a hidden epigenetic clock in mitochondria reveals a "lifespan limit line"
Building on their work on epigenetics of aging and transposable elements, researchers Dr. Ádám Sturm and Dr. Tibor Vellai from Eötvös Loránd University have made another advance in understanding the molecular mechanisms of aging. Their latest st.....»»
3D shapes of viral proteins point to previously unknown roles
Viruses are tricky to keep up with. They evolve quickly and regularly develop new proteins that help them infect their hosts. These rapid shifts mean that researchers are still trying to understand a multitude of viral proteins and precisely how they.....»»
From antiquity to adaptation: Tracing the genetic journey of east Asian chestnut varieties
Uncovering the genetic saga of Castanea trees, a study maps their evolutionary journey and local climate adaptations. This research reveals the genetic markers and molecular mechanisms that have allowed these nut fruit trees to adapt and flourish acr.....»»
Controlling molecular electronics with rigid, ladder-like molecules
As electronic devices continue to get smaller and smaller, physical size limitations are beginning to disrupt the trend of doubling transistor density on silicon-based microchips approximately every two years, according to Moore's law. Molecular elec.....»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
Stranded student helps design synthetic polymers to combat fungal infections
Every year, more than 2 million people are affected by invasive fungal infections, which are often caused by Candida species and are associated with high mortality rates. The development of new therapies is progressing very slowly. Demand is increasi.....»»
How Twitter—now X—helps with understanding Canadian values and attitudes toward asylum seekers
The treatment of asylum seekers is an important issue for many countries as they grapple with polarized public views on the issue. Some policymakers focus on the need for border security to keep asylum-seekers out and "protect" their nations, while o.....»»
A small molecular glue that increases P53 level and suppresses tumor growth in vivo
Molecular glues are typically small chemical molecules that act on the interface between the target protein and the degradation machinery to trigger ternary complex formation. Identification of molecular glues is challenging, and there has been a lac.....»»
How particles of light may be producing drops of the perfect liquid
The world's largest and most powerful particle accelerator may be producing the world's tiniest droplets of liquid, right under scientists' noses. Researchers are digging into this subatomic enigma......»»
Doctor decries Apple gift card discount "scam" after failing to understand the terms of the deal
An academic with a sideline in TikTok videos about marketing scams claims Apple defrauded her over an iPad discount — despite her getting precisely the deal she was promised and should have expected.Apple gift cardsThis will shock you, but it's pos.....»»
Physicists observe key minuscule molecular interactions in ultra-fast atomic processes

Astronomers think they’ve found a plausible explanation of the Wow! signal
Magnetars could zap clouds of atomic hydrogen, producing focused microwave beams. Enlarge / The Wow! signal, represented as "6EQUJ5," was discovered in 1977 by astronomer Jerry Ehman. (credit: Public domain) An unusually.....»»
The Wow! Signal deciphered—it was hydrogen all along, study says
In 1977, astronomers received a powerful, peculiar radio signal from the direction of the constellation Sagittarius. Its frequency was the same as neutral hydrogen, and astronomers had speculated that any ETIs attempting to communicate would naturall.....»»
Bacteria make thermally stable plastics similar to polystyrene and PET for the first time
Bioengineers around the world have been working to create plastic-producing microbes that could replace the petroleum-based plastics industry. Now, researchers from Korea have overcome a major hurdle: getting bacteria to produce polymers that contain.....»»
Twisted molecular wires exhibit high single-molecule conductance
From the high-voltage wires that carry electricity over long distances, to the tungsten filaments in our incandescent lights, we may have become accustomed to thinking that electrical conductors are always made of metal. But for decades, scientists h.....»»
Newly discovered, free-living eukaryote is the first known to have lost its mitochondria
