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.

Doctors recommend making fruits and vegetables a foundational part of the treatment of patients with hypertension. Diets high in fruits and vegetables are found to lower blood pressure, reduce cardiovascular risk, and improve kidney health due to their base-producing effects. A new study details the findings from a five-year interventional randomized control trial.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Researchers have developed a compound that is effective against common bacteria that can lead to rare, dangerous illnesses.

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.
