A chemical element so visually striking that it was named for a goddess shows a “Goldilocks” level of reactivity — neither too much nor too little — that makes it a strong candidate as a carbon scrubbing tool. The element is vanadium, and research by Oregon State University scientists has demonstrated the ability of vanadium Read more about Key advance for capturing carbon from the air[…]
Global warming is largely caused by carbon dioxide and other gases absorbing infrared radiation, trapping heat in Earth’s atmosphere – known as the greenhouse effect. The most accurate climate models use precise measurements of the amount of radiation CO₂ can absorb to calculate how much heat will be trapped in the atmosphere. These models are Read more about Fermi Resonance explains why carbon dioxide causes global warming[…]

A new approach could solve this problem: Tiny spherical containers are created with a high-resolution 3D printer. These containers are then filled with cells and assembled into the desired Read more about Artificial cartilage with the help of 3D printing[…]
Researchers have profiled the entire immune system in young children to compare their response to SARS-CoV-2 with that of adults. The results, published in Cell, show that infants’ systems mount a strong innate response in their noses, where the airborne virus usually enters the body. And unlike adults, babies don’t exhibit widespread inflammatory signaling throughout Read more about Here’s Why Infants Are Strangely Resistant to COVID[…]
Delivering medication to the lungs with inhalable nanoparticles may help treat chronic obstructive pulmonary disease (COPD). In mice with signs of the condition, the treatment improved lung function and reduced inflammation. COPD causes the lungs’ airways to become progressively narrower and more rigid, obstructing airflow and preventing the clearance of mucus. As a result, mucus Read more about COPD: Inhalable nanoparticles could help treat chronic lung disease[…]
The rainbow looks different to a human than it does to a honeybee or a zebra finch. That’s because these animals can see colors that we humans simply can’t. Now scientists have developed a new video recording and analysis technique to better understand how the world looks through the eyes of other species. The accurate Read more about Animals Can See Colors We Can’t. A New camera method gives us a good idea.[…]
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 why, by using artificial membranes that mimic the behavior of natural ones. Their discovery could make a Read more about Cells’ electric fields keep nanoparticles at bay, scientists confirm[…]

A new study published in The Astrophysical Journal reveals new evidence for standard gravity breaking down in an idiosyncratic manner at low acceleration. This new study reinforces the evidence for modified gravity that was previously reported in 2023 from an analysis of the orbital motions of gravitationally bound, widely separated (or long-period) binary stars, known Read more about Study of wide binary stars reveals new evidence for modified gravity at low acceleration[…]
[…] Curceanu hopes the apparatus and methods of nuclear physics can solve the century-old mystery of why lentils – and other organisms too – constantly emit an extremely weak dribble of photons, or particles of light. Some reckon these “biophotons” are of no consequence. Others insist they are a subtle form of lentil communication. Curceanu Read more about Biophotons: Are lentils communicating using quantum light messages?[…]
It sounds like a simple, well-known everyday phenomenon: there is high pressure in a champagne bottle, the stopper is driven outwards by the compressed gas in the bottle and flies away with a powerful pop. But the physics behind this is complicated. […] Using complex computer simulations, it was possible to recalculate the behavior of Read more about Clarified at last: The physics of popping champagne[…]
The typical strategy when treating microbial infections is to blast the pathogen with an antibiotic drug, which works by getting inside the harmful cell and killing it. This is not as easy as it sounds, because any new antibiotic needs to be both water soluble, so that it can travel easily through the bloodstream, and Read more about Research team discovers how to sabotage antibiotic-resistant ‘superbugs’[…]
This article was originally featured on The Conversation. The global anti-vaccine movement and vaccine hesitancy that accelerated during the COVID-19 pandemic show no signs of abating. According to a survey of U.S. adults, Americans in October 2023 were less likely to view approved vaccines as safe than they were in April 2021. As vaccine confidence falls, health misinformation continues Read more about Health misinformation is rampant on social media[…]
