Published Flapping frequency of birds, insects, bats and whales described by universal equation
(via sciencedaily.com) Original source A single universal equation can closely approximate the frequency of wingbeats and fin strokes made by birds, insects, bats and whales, despite their different body sizes and wing shapes, researchers report in a new study.
Published Bone loss drugs can help azoles fight fungal infections
(via sciencedaily.com) Original source A new study suggests that adding common bone loss drugs to azoles can improve efficacy when treating fungal infections.
Published Unlocking the world around us for next-gen antibiotics
(via sciencedaily.com) Original source An international research team has found almost a million potential sources of antibiotics in the natural world.
Published New technique reveals how gene transcription is coordinated in cells
(via sciencedaily.com) Original source Researchers invented a technique that allows them to observe which genes and enhancers are active in a cell at the same time. This could help them determine which enhancers control which genes and may reveal potential new drug targets for genetic disorders.
Published Father's diet before conception influences children's health
(via sciencedaily.com) Original source A recent study provides new insights into how fathers' diets and overweight can affect their children's health even before conception. The findings of the study can help develop preventive health measures for men wishing to become fathers: The healthier the father's diet, the lower the risk for their children to develop obesity or diseases such as diabetes later in life.
Published Exercising during pregnancy normalizes eating behaviors in offspring from obese mice
(via sciencedaily.com) Original source Maternal obesity impacts the eating behaviors of offspring via long-term overexpression of the microRNA miR-505-5p, according to a new study.
Published Giant viruses found on Greenland ice sheet
(via sciencedaily.com) Original source Giant viruses found on the Greenland ice sheet probably regulate the growth of snow algae on the ice by infecting them. Knowing how to control these viruses could help us reduce the rate of ice-melt.
Published An anti-inflammatory curbs spread of fungi causing serious blood infections
(via sciencedaily.com) Original source Study finds that mesalamine, a common anti-inflammatory drug, can fight the fungus Candida albicans in the gut, potentially preventing the risk of invasive candidiasis in patients with blood cancers.
Published Human activity contributed to woolly rhinoceros' extinction
(via sciencedaily.com) Original source Researchers have discovered sustained hunting by humans prevented the woolly rhinoceros from accessing favourable habitats as Earth warmed following the Last Ice Age.
Published Small, but smart: How symbiotic bacteria adapt to big environmental changes
(via sciencedaily.com) Original source Lucinid clams, inconspicuous inhabitants of the seafloor and one of the most diverse group of animals in the ocean, rely on symbiotic bacteria for their survival. Researchers now reveal the evolutionary journey of these tiny tenants. Faced with a drastically changing environment following the closure of the Isthmus of Panama, they acquired new metabolic skills to enable their own survival. Understanding the adaptive strategies of bacteria provides insight into their potential responses to challenging environmental changes, such as those caused by human activities.
Published New light shed on circadian rhythms
(via sciencedaily.com) Original source Circadian clocks, which drive circadian rhythms, are entwined with many essential systems in living things including plants, fungi, insects, and even humans. Because of this, disruptions to our circadian clocks are linked to higher disease rates in humans, including certain cancers and autoimmune diseases.
Published Oral nucleoside antiviral is progressing toward future pandemic preparedness
(via sciencedaily.com) Original source Obeldesivir (GS-5245), a novel investigational small molecule oral antiviral, represents a new tool in the ongoing effort to prepare for future pandemics.
Published Wire snare removal in protected areas is labor-intensive but effective -- and essential to solving the Southeast Asian snaring crisis
(via sciencedaily.com) Original source Snaring -- a non-selective method of poaching using wire traps -- is widespread in tropical forests in Southeast Asia. Snaring decimates wildlife populations and has pushed many larger mammals to local or even global extinction. Eleven years of data from ranger patrols in the Thua Thien Hue and Quang Nam Saola Nature Reserves in Viet Nam show that intensive removal efforts are labour-intensive and costly but brought snaring down by almost 40 percent and therefore reduced imminent threats to wildlife. Further reductions were difficult to achieve despite continued removal efforts. Snare removal is therefore necessary but by itself not sufficient to save the threatened wildlife diversity in tropical forests, scientists conclude.
Published Fungus breaks down ocean plastic
(via sciencedaily.com) Original source A fungus living in the sea can break down the plastic polyethylene, provided it has first been exposed to UV radiation from sunlight. Researchers expect that many more plastic degrading fungi are living in deeper parts of the ocean.
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 Antibodies may aid effort to fight influenza B
(via sciencedaily.com) Original source Researchers have isolated human monoclonal antibodies against influenza B, a significant public health threat that disproportionately affects children, the elderly and other immunocompromised individuals.
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 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 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.
