Published Crucial shift in River Nile's evolution during ancient Egypt discovered
(via sciencedaily.com) Original source Researchers have explored how the River Nile evolved over the past 11,500 years and how changes in its geography could have helped shape the fortunes of ancient Egyptian civilization. Research reveals a major shift in the Nile around four thousand years ago, after which the floodplain in the Nile Valley around Luxor greatly expanded.
Published Captivating blue-colored ant discovered in India's remote Siang Valley
(via sciencedaily.com) Original source A new species of blue ant was discovered in Yingku village in Arunachal Pradesh, Northeastern India. It was named Paraparatrechina neela, after the word 'neela' which means blue in various Indian languages. Its unique blue coloration makes it stand out among other ant species.
Published Food drove the evolution of giraffes' long neck
(via sciencedaily.com) Original source A study explores body proportions of Masai giraffes, lending insight into why giraffes have such long necks and how this trait might have evolved.
Published Kinship and ancestry of the Celts in Baden-Württemberg, Germany
(via sciencedaily.com) Original source The Celtic culture of the pre-Roman Iron Age in Western and Central Europe has left numerous traces to this day, not least in the form of enormous burial mounds and spectacular archaeological artifacts. Despite this rich legacy, much about this civilization remains hidden from us.
Published How sharks survived a major spike in Earth's temperature
(via sciencedaily.com) Original source The sharks we know today as the open ocean's top predators evolved from stubby bottom dwellers during a dramatic episode of global warming millions of years ago.
Published Paving the way for hydrogen from algae enzymes
(via sciencedaily.com) Original source Under certain conditions, some algae are able to produce hydrogen -- a much sought-after green energy source. Its production takes place in the unique catalytic center of the unicellular algae and is only possible if certain cofactors of the relevant proteins are present. Researchers have identified how such a cofactor, the so-called hydrogen cluster, is assembled. Specifically, they describe the previously unexplained role of the enzyme HydF, which is involved in the final steps of assembly.
Published Researchers discover 'trojan horse' virus hiding in human parasite
(via sciencedaily.com) Original source An international team has found a new RNA virus that they believe is hitching a ride with a common human parasite. The virus is associated with severe inflammation in humans infected with the parasite Toxoplasma gondii, leading the team to hypothesize that it exacerbates toxoplasmosis disease.
Published Lighting up the brain: What happens when our 'serotonin center' is triggered?
(via sciencedaily.com) Original source Scientists have studied the main source of serotonin in the brain -- the dorsal raphe nucleus (DRN). By studying how activating the brain's 'serotonin center' affects awake animals for the first time, they found that serotonin from the DRN activates brain areas that affect behavior and motivation. Results show that DRN serotonin stimulation causes activation of the cerebral cortex and the basal ganglia, brain areas involved in many cognitive functions.
Published The world's most powerful anti-fungal chemistries cause fungal pathogens to self-destruct
(via sciencedaily.com) Original source Scientists have discovered that the most widely-used class of antifungals in the world cause pathogens to self-destruct. The research could help improve ways to protect food security and human lives.
Published Mediterranean diet tied to one-fifth lower risk of early death in women
(via sciencedaily.com) Original source In a new study that followed more than 25,000 initially healthy U.S. women for up to 25 years, researchers found that participants who had greater Mediterranean diet intake had up to 23% lower risk of all-cause mortality, with benefits for both cancer mortality and cardiovascular mortality.
Published Trout in mine-polluted rivers are genetically 'isolated'
(via sciencedaily.com) Original source Trout living in rivers polluted by metal from old mines across the British Isles are genetically 'isolated' from other trout, new research shows.
Published New coral disease forecasting system
(via sciencedaily.com) Original source Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.
Published New, modified CRISPR protein can fit inside virus used for gene therapy
(via sciencedaily.com) Original source Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells.
Published Novel virus identified in zebrafish from the pet trade causes disease in laboratory fish
(via sciencedaily.com) Original source Zebrafish in the pet trade are asymptomatic carriers of previously undescribed microbes, including a novel virus that causes hemorrhaging in infected laboratory fish, researchers report.
Published Scientists develop visual tool to help people group foods based on their levels of processing
(via sciencedaily.com) Original source Scientists studying ultra-processed foods have created a new tool for assessing the rewarding and reinforcing properties of foods that make up 58 percent of calories consumed in the United States. The foods have been linked to a wide range of negative health outcomes.
Published Rapid urbanization in Africa transforms local food systems and threatens biodiversity
(via sciencedaily.com) Original source Urbanization in Africa is accelerating quickly, showing no signs of slowing down. An international team of researchers addresses critical gaps in our understanding of how this urbanization affects local food and ecological systems, emphasizing the importance of recognizing shifts in dietary patterns.
Published Tracing the evolution of ferns' surprisingly sweet defense strategy
(via sciencedaily.com) Original source Plants and the animals that eat them have evolved together in fascinating ways, creating a dynamic interplay of survival strategies. Many plants have developed physical and chemical defenses to fend off herbivores. A well-known strategy in flowering plants is to produce nectar to attract 'ant bodyguards.' Recent research explores the evolution of this same defense strategy in ferns.
Published Antibiotic pollution disrupts the gut microbiome and blocks memory in aquatic snails
(via sciencedaily.com) Original source Antibiotics prevent snails from forming new memories by disrupting their gut microbiome -- the community of beneficial bacteria found in their guts.
Published Researchers expose new symbiosis origin theories, identify experimental systems for plant life
(via sciencedaily.com) Original source Research work on symbiosis -- a mutually beneficial relationship between living organisms -- is pushing back against the newer theory of a 'single-origin' of root nodule symbiosis (RNS) -- that all symbiosis between plant root nodules and nitrogen-fixing bacteria stems from one point--instead suggesting a 'multiple-origin' theory of sybiosis which opens a better understanding for genetically engineering crops.
Published Researchers apply quantum computing methods to protein structure prediction
(via sciencedaily.com) Original source Researchers recently published findings that could lay the groundwork for applying quantum computing methods to protein structure prediction.
