Do smells prime our gut to fight off infection?      (via sciencedaily.com)     Original source 

In nematodes and humans, mitochondrial stress in the nervous system initiates a whole-body response that is most pronounced in the gut. A recent study showed that in nematodes, the odor of a pathogen triggers the nervous system to broadcast this response to the rest of the organism, prepping mitochondria in intestinal cells to fight a bacterial infection. Humans, too, may be able to sense pathogenic odors that prepare the gut for an infection.

New device for on-the-spot water testing      (via sciencedaily.com)     Original source 

Researchers at University of Galway have developed a new, portable technology for on-the-spot testing of water quality to detect one of the most dangerous types of bacteria. Ireland regularly reports the highest crude incidence rates of the pathogen Shiga toxigenic Escherichia coli -- STEC for short -- in Europe over the recent years.

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.

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.

Link between global warming and rising sea levels      (via sciencedaily.com)     Original source 

A new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought.

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.

New research sheds light on relationships between plants and insects in forest ecosystems      (via sciencedaily.com)     Original source 

Researchers have published new findings on how leaf-eating insects affect forest ecosystems worldwide. Researchers are aware of how large herbivores cycle nutrients in forests. They know much less, however, about how leaf-eating insects impact forest carbon and nutrient cycling.

Scientists find a human 'fingerprint' in the upper troposphere's increasing ozone      (via sciencedaily.com)     Original source 

Scientists confirmed that much of ozone's increase in the upper troposphere is likely due to humans. A team detected a clear signal of human influence on upper tropospheric ozone trends in a 17-year satellite record starting in 2005.

Genetic signatures of domestication identified in pigs, chickens      (via sciencedaily.com)     Original source 

Wild boars and red junglefowl gave rise to common pigs and chickens. These animals' genes evolved to express themselves differently, leading to signatures of domestication -- such as weaker bones and better viral resistance -- in pigs and chickens, according to a research team.

Talking about regeneration      (via sciencedaily.com)     Original source 

Researchers transferred genes from simple organisms capable of regenerating their bodies into common fruit flies, more complex animals that cannot. They found the transferred gene suppressed an age-related intestinal issue in the flies. Their results suggest studying genes specific to animals with high regenerative capability may uncover new mechanisms for rejuvenating stem cell function and extending the healthy lifespan of unrelated organisms.
