Advanced chelators offer efficient and eco-friendly rare earth element recovery      (via sciencedaily.com)     Original source 

The world is going to need a lot of weird metals in the coming years, according to chemistry professor. But he isn't talking about lithium, cobalt or even beryllium. He's interested in dysprosium, which is so hidden in the periodic table that you'd be forgiven for thinking he made it up.

Stacking molecules like plates improves organic solar device performance      (via sciencedaily.com)     Original source 

Researchers found that how well light-converting molecules stack together in a solid is important for how well they convert light into electric current. A rigid molecule that stacked well showed excellent electricity generation in an organic solar cell and photocatalyst, easily outperforming a similar flexible molecule that did not stack well. This new way of improving the design of molecules could be used to pioneer the next generation of light-converting devices.

Soft gold enables connections between nerves and electronics      (via sciencedaily.com)     Original source 

Gold does not readily lend itself to being turned into long, thin threads. But researchers have now managed to create gold nanowires and develop soft electrodes that can be connected to the nervous system. The electrodes are soft as nerves, stretchable and electrically conductive, and are projected to last for a long time in the body.

Live longer, die healthier      (via sciencedaily.com)     Original source 

Everyone wants to live to a ripe old age, but no one wants to be decrepit. Now, researchers demonstrated a treatment that could lengthen life -- and vigor -- up to the very end. Gerontologists describe how a group of mice lived 9% longer when they received monthly treatments, walking faster and gripping objects with greater strength than untreated mice of the same age.

Horse miscarriages offer clues to causes of early human pregnancy loss      (via sciencedaily.com)     Original source 

A study of horses -- which share many important similarities with humans in their chromosomes and pregnancies -- revealed that 42% of miscarriages and spontaneous abortions in the first two months of pregnancy were due to complications from an extra set of chromosomes, a condition called triploidy.

Preventing Parkinson's disease may lie in seaweed antioxidants      (via sciencedaily.com)     Original source 

A research team examined the effect of Ecklonia cava polyphenols on the prevention of Parkinson's disease. It was found that the oral intake of the seaweed antioxidants restores motor function and protects dopaminergic neurons in model mice, while cellular experiments revealed the biochemical interaction of their preventive effect.

First measurement of electron- and muon-neutrino interaction rates at the highest energy ever detected from an artificial source      (via sciencedaily.com)     Original source 

Understanding neutrino interactions is crucial for obtaining a complete picture of particle physics and the universe. To date, neutrino interaction cross sections have not been measured at high energy above some hundred gigaelectronvolts at particle colliders. Now, researchers have obtained the first direct observation of electron and muon neutrino interactions in the Teraelectronvolt range at CERN's Large Hadron Collider, using the FASER detector. This study marks a significant step for particle physics research.

Cracking the code of life: new AI model learns DNA's hidden language      (via sciencedaily.com)     Original source 

With GROVER, a new large language model trained on human DNA, researchers could now attempt to decode the complex information hidden in our genome. GROVER treats human DNA as a text, learning its rules and context to draw functional information about the DNA sequences.

'Laser view' into the avocado: New method reveals cell interior      (via sciencedaily.com)     Original source 

Checking whether an avocado is hard or soft by looking at it? This would require recognizing how the plant cells behave behind the skin. The same applies to all other cells on our planet: Despite more than 100 years of intensive research, many of their properties remain hidden inside the cell. Researchers now describe a new approach that can determine the particularly difficult-to-detect mechanical properties of the cell interior by taking a closer look.

Improving cat food flavors with the help of feline taste-testers      (via sciencedaily.com)     Original source 

Cats are notoriously picky eaters. But what if we could design their foods around flavors that they're scientifically proven to enjoy? Researchers used a panel of feline taste-testers to identify favored flavor compounds in a series of chicken-liver-based sprays. The cats particularly enjoyed the sprays that contained more free amino acids, which gave their kibble more savory and fatty flavors.

Discovery of a new population of macrophages promoting lung repair after viral infections      (via sciencedaily.com)     Original source 

Researchers have discovered a new population of macrophages, important innate immune cells that populate the lungs after injury caused by respiratory viruses. These macrophages are instrumental in repairing the pulmonary alveoli. This groundbreaking discovery promises to revolutionize our understanding of the post-infectious immune response and opens the door to new regenerative therapies.

Allergy cells' hidden secret      (via sciencedaily.com)     Original source 

Known for their role in allergic reactions, mast cells have long been recognised as key players in our immune system. When they encounter allergens, they release chemicals that trigger typical allergy symptoms such as tissue swelling and inflammation. Now, researchers have discovered a hidden talent of mast cells: they can capture and use another type of immune cell called neutrophils. This surprising discovery sheds new light on how our immune system works, particularly during allergic reactions.

Coinfecting viruses impede each other's ability to enter cells      (via sciencedaily.com)     Original source 

The process by which phages -- viruses that infect and replicate within bacteria -- enter cells has been studied for over 50 years. In a new study, researchers have used cutting-edge techniques to look at this process at the level of a single cell.
