Mix of factors prompts owl monkeys to leave their parents      (via sciencedaily.com)     Original source 

There comes a point in the lives of young owl monkeys when they leave their parents and strike out on their own to find a mate. In a new study of a wild population of Azara's owl monkeys in northern Argentina, researchers reveal that a combination of social and ecological factors influences when these tree-dwelling monkeys peel away from their parents and siblings. According to their findings -- which were based on 25 years of genetic and demographic data for several generations of owl monkeys, covering more than 330 individuals -- none of the individuals, regardless of their sex, reproduced in the same group where they were born. In all cases, the researchers found, the animals either departed from their natal group or died before reproducing.

Viral defense protein speeds up female stem cell production      (via sciencedaily.com)     Original source 

A viral defense mechanism can be used to accelerate the creation of female stem cell lines in mice. The findings can boost efforts in medical research, drug testing, and regenerative therapies, particularly for women and individuals with two X chromosomes.

Forever chemical pollution can now be tracked      (via sciencedaily.com)     Original source 

Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.

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.

Elephants on the move: Mapping connections across African landscapes      (via sciencedaily.com)     Original source 

Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change.

Researchers find gene which determines marsupial fur color      (via sciencedaily.com)     Original source 

Fur is a defining characteristic of mammals, coming in a wide variety of colors and patterns -- thanks to a world-first study, we now know which genes make a marsupial's coat black or grey.

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.

Reduction in folate intake linked to healthier aging in animal models      (via sciencedaily.com)     Original source 

Scientists found that decreasing folate intake can support healthier metabolisms in aging animal models, challenging the conventional belief that high folate consumption universally benefits health.
