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.

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.

Estuaries in South Florida have experienced rapid warming over the past two decades, including a record-breaking marine heat wave in 2023, research shows. The findings paint a troubling picture for the marine life that calls Florida home. Possible causes include evaporation, water capacity and residence time (the amount of time water spends in an estuary). No single factor has been identified as dominant.

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.

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.

A new paper describes a ground-breaking experiment that united 25 independent taxonomists from 10 countries. The initiative boasts the discovery of 11 new marine species from all over the globe, occurring at depths from 5.2 to 7081 meters. It also represents a significant step forward in accelerating the pace at which new marine species are described and published.

Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.

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.

The rising earth beneath the Antarctic Ice Sheet will likely become a major factor in future sea level rise, a new study suggests.

     (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.

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.

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.

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.

Unravelling the complexities of circular RNAs (circRNAs) in cancer biology has positioned scientists on the cusp of revolutionary breakthroughs in the diagnosis and treatment of cancer. A new study predicts remarkable potential for circular RNAs to improve cancer treatment and patient outcomes within the next 5-10 years.

Shifts in the Earth's continental plates that drove long-term changes in sea level set the stage for the evolution of the earliest animals on Earth, a study suggests.

A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.
