Water delivered to the mantle by aluminum enriched hydrated slabs?      (via sciencedaily.com)     Original source 

Researchers found a notable effect of aluminum on the sound velocities of superhydrous phase B, a dense hydrous magnesium silicate and potential host of water in the deep Earth. Their results suggest that aluminous phase B could explain seismic velocity anomalies in the Earth's mantle transition region and uppermost lower mantle.

Type 2 diabetes can be prevented by diet and exercise even in individuals with a high genetic risk      (via sciencedaily.com)     Original source 

A new study shows that a healthy diet and regular exercise reduce the risk of type 2 diabetes even in individuals with a high genetic risk. In other words, everyone benefits from lifestyle changes, regardless of genetic risk.

Plants offer fruit to insects to disperse dust-like seeds      (via sciencedaily.com)     Original source 

Fruit exist to invite animals to disperse the swallowed seeds. A research team found that plants targeting insects rather than birds or mammals for this service are more common than previously thought. These plants produce dust-like seeds and fruit suitable for the minute, ground-dwelling animals.

Scientists uncover hidden forces causing continents to rise      (via sciencedaily.com)     Original source 

Scientists have answered one of the most puzzling questions in plate tectonics: how and why 'stable' parts of continents gradually rise to form some of the planet's greatest topographic features.

Nasal microbiome: Depriving multi-resistant 'bugs' of iron      (via sciencedaily.com)     Original source 

Whether dangerous staphylococci survive in the nose depends on what other bacteria are present -- and how they obtain iron.

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.

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.

Greenland fossil discovery reveals increased risk of sea-level catastrophe      (via sciencedaily.com)     Original source 

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.

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.

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.

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.
