Published 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.
Published Pesticide contamination is more than apple skin deep
(via sciencedaily.com) Original source Pesticides and herbicides are critical to ensuring food security worldwide, but these substances can present a safety risk to people who unwittingly ingest them. Protecting human health, therefore, demands sensitive analytical methods to identify even trace levels of potentially harmful substances. Now, researchers have developed a high-tech imaging method to detect pesticide contamination at low levels, and its application on fruits reveals that current food safety practices may be insufficient.
Published South Florida estuaries warming faster than Gulf of Mexico, global ocean, USF research shows
(via sciencedaily.com) Original source 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.
Published 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.
Published 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.
Published 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.
Published Eating more fruits and vegetables to reduce dietary acid lowers blood pressure and improves kidney and heart health in patients with hypertension
(via sciencedaily.com) Original source 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.
Published The race to discover biodiversity: 11 new marine species and a new platform for rapid species description
(via sciencedaily.com) Original source 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.
Published Ketogenic Diet may reduce friendly gut bacteria and raise cholesterol levels
(via sciencedaily.com) Original source A study reveals that ketogenic low-carbohydrate diets can increase cholesterol levels and reduce beneficial gut bacteria, specifically Bifidobacterium.
Published A new way of thinking about the economy could help protect the Amazon, and help its people thrive
(via sciencedaily.com) Original source To protect the Amazon and support the wellbeing of its people, its economy needs to shift from environmentally harmful production to a model built around the diversity of indigenous and rural communities, and standing forests.
Published Antarctic-wide survey of plant life to aid conservation efforts
(via sciencedaily.com) Original source The first continent-wide mapping study of plant life across Antarctica reveals growth in previously uncharted areas and is set to inform conservation measures across the region. The satellite survey of mosses, lichens and algae across the continent will form a baseline for monitoring how Antarctica's vegetation responds to climate change.
Published 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.
Published 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.
Published Forecasting climate's impact on a debilitating disease
(via sciencedaily.com) Original source In Brazil, climate and other human-made environmental changes threaten decades-long efforts to fight schistosomiasis, a widespread and debilitating parasitic disease. Now, researchers have developed models that can predict how the disease risk will shift in response to environmental changes.
Published 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.
Published 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.
Published Why virus causing cold sores does not spread to devastating brain infection
(via sciencedaily.com) Original source A previously unknown defence mechanism in the brain prevents herpesvirus from infecting the brain's nerve cells.
Published New model refutes leading theory on how Earth's continents formed
(via sciencedaily.com) Original source Computational modeling shows that plate tectonics weren't necessary for early continents.
Published '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.
Published How the rising earth in Antarctica will impact future sea level rise
(via sciencedaily.com) Original source The rising earth beneath the Antarctic Ice Sheet will likely become a major factor in future sea level rise, a new study suggests.
