Nanoscopic imaging aids in understanding protein, tissue preservation in ancient bones      (via sciencedaily.com)     Original source 

A pilot study shows that nanoscopic 3-D imaging of ancient bone not only provides further insight into the changes soft tissues undergo during fossilization, it also has potential as a fast, practical way to determine which specimens are likely candidates for ancient DNA and protein sequence preservation.

Maximizing hydrogen peroxide formation during water electrolysis      (via sciencedaily.com)     Original source 

When water is split electrolytically, the result is typically hydrogen -- and 'useless' oxygen. Instead of oxygen, you can also produce hydrogen peroxide, which is required for many branches of industry. This, however, requires certain reaction conditions.

Waste Styrofoam can now be converted into polymers for electronics      (via sciencedaily.com)     Original source 

A new study describes a chemical reaction that can convert Styrofoam into a high-value conducting polymer known as PEDOT:PSS. Researchers also noted that the upgraded plastic waste can be successfully incorporated into functional electronic devices, including silicon-based hybrid solar cells and organic electrochemical transistors.

Converting wastewater to fertilizer with fungal treatment      (via sciencedaily.com)     Original source 

Creating fertilizers from organic waste can help reduce the consumption of fossil fuels and promote sustainable production. One way of doing this is through hydrothermal liquefaction (HTL), which converts biomass into biocrude oil through a high-temperature, high-pressure process. Two studies explore the use of a fungal treatment to convert the leftover wastewater into fertilizer for agricultural crops.

Another intermediate-mass black hole discovered at the center of our galaxy      (via sciencedaily.com)     Original source 

So far, only about ten intermediate-mass black holes have been discovered in the entire universe. The newly identified black hole causes surrounding stars in a cluster to move in an unexpectedly orderly way.

Microbes found to destroy certain 'forever chemicals'      (via sciencedaily.com)     Original source 

An environmental engineering team has discovered that specific bacterial species can cleave the strong fluorine-to-carbon bond certain kinds of 'forever chemical' water pollutants, offering promise for low-cost treatments of contaminated drinking water.

A new addition to the CRISPR toolbox: Teaching the gene scissors to detect RNA      (via sciencedaily.com)     Original source 

CRISPR-Cas systems, defense systems in bacteria, have become a plentiful source of technologies for molecular diagnostics. Researchers have now expanded this extensive toolbox further. Their novel method, called PUMA, enables the detection of RNA with Cas12 nucleases, which naturally target DNA. PUMA promises a wide range of applications and high accuracy.

Sun-like stars found orbiting hidden companions      (via sciencedaily.com)     Original source 

Astronomers have uncovered what appear to be 21 neutron stars in orbit around stars like our Sun. The discovery is surprising because it is not clear how a star that exploded winds up next to a star like our Sun.

Transporting precious cargo using the body's own delivery system      (via sciencedaily.com)     Original source 

Delivery systems in body continuously move materials between cells. Hijacking these systems allowed scientists to improve loading and delivery of therapeutic proteins. Biophysical principles could be used to enable more cost-effective loading of biological cargo into cell-derived delivery systems. Engineered molecules loaded up to 240 times more protein than other loading methods.

JWST unveils stunning ejecta and CO structures in Cassiopeia A's young supernova      (via sciencedaily.com)     Original source 

Researchers announced the latest findings from the James Webb Space Telescope (JWST) of the supernova remnant, Cassiopeia A (Cas A). These observations of the youngest known core collapse supernova in the Milky Way provide insights into the conditions that lead to the formation and destruction of molecules and dust within supernova ejecta. The study's findings change our understanding of dust formation in the early universe in the galaxies detected by JWST 300 million years after the Big Bang.

Cosmic wrestling match      (via sciencedaily.com)     Original source 

Our universe is around 13.8 billion years old. Over the vastness of this time, the tiniest of initial asymmetries have grown into the large-scale structures we can see through our telescopes in the night sky: galaxies like our own Milky Way, clusters of galaxies, and even larger aggregations of matter or filaments of gas and dust. How quickly this growth takes place depends, at least in today's universe, on a sort of wrestling match between natural forces: Can dark matter, which holds everything together through its gravity and attracts additional matter, hold its own against dark energy, which pushes the universe ever further apart?

Vivid portrait of interacting galaxies marks Webb's second anniversary      (via sciencedaily.com)     Original source 

Two for two! A duo of interacting galaxies commemorates the second science anniversary of NASA's James Webb Space Telescope, which takes constant observations, including images and highly detailed data known as spectra. Its operations have led to a 'parade' of discoveries by astronomers around the world.

A better way to make RNA drugs      (via sciencedaily.com)     Original source 

RNA drugs are the next frontier of medicine, but manufacturing them requires an expensive and labor-intensive process that limits production and produces metric tons of toxic chemical waste. Researchers report a new, enzyme-based RNA synthesis method that can produce strands of RNA with both natural and modified nucleotides without the environmental hazards.

Scientists have created a computer program that 'paints' the structure of molecules in the style of famous Dutch artist, Piet Mondrian. Researchers are opening eyes and minds to the beauty of molecular structure, as well as posing new questions about the form and function of the molecules themselves.

How the 'heart and lungs' of a galaxy extend its life      (via sciencedaily.com)     Original source 

Galaxies avoid an early death because they have a 'heart and lungs' which effectively regulate their 'breathing' and prevent them growing out of control, a new study suggests. If they didn't, the universe would have aged much faster than it has and all we would see today is huge 'zombie' galaxies teeming with dead and dying stars. That's according to a new study that investigates one of the great mysteries of the Universe -- why galaxies are not as large as astronomers would expect.

Nanoplastics and 'forever chemicals' disrupt molecular structures, functionality      (via sciencedaily.com)     Original source 

Researchers have made significant inroads in understanding how nanoplastics and per- and polyfluoroalkyl substances (PFAS) -- commonly known as forever chemicals -- disrupt biomolecular structure and function. The work shows that the compounds can alter proteins found in human breast milk and infant formulas -- potentially causing developmental issues downstream.
