Molecular ‘switch’ reverses chronic inflammation and aging

Hourglass, aging concept (stock image). Credit: © photosaint / Adobe Stock Chronic inflammation, which results when old age, stress or environmental toxins keep the body's immune system in overdrive, can contribute to a variety of devastating diseases, from Alzheimer's and Parkinson's to diabetes and cancer. Now, scientists at the University of California, Berkeley, have identified…

Normal resting heart rate appears to vary widely from person to person

Monitoring heart rate (stock image). Credit: © VILevi / Adobe Stock A person's normal resting heart rate is fairly consistent over time, but may vary from others' by up to 70 beats per minute, according to analysis of the largest dataset of daily resting heart rate ever collected. Giorgio Quer of the Scripps Research Translational…

Cancer mutations occur decades before diagnosis

Cancer diagnosis concept (stock image). Credit: © vchalup / Adobe Stock Researchers at EMBL's European Bioinformatics Institute (EMBL-EBI) and the Francis Crick Institute have analysed the whole genomes of over 2600 tumours from 38 different cancer types to determine the chronology of genomic changes during cancer development. Cancer occurs as part of a lifelong process…

Why males pack a powerful punch

Man's fist (stock image). Credit: © cineberg / Adobe Stock Elk have antlers. Rams have horns. In the animal kingdom, males develop specialized weapons for competition when winning a fight is critical. Humans do too, according to new research from the University of Utah. Males' upper bodies are built for more powerful punches than females',…

Scientists document collapse of the white-lipped peccary

Peccary (stock image). Credit: © KikkiaJackson / Adobe Stock White-lipped peccaries have declined by as much as 87% to 90% from their historical range in Central America, signaling a population collapse of a key species in the region, according to a study published recently in the journal Biological Conservation. The research was conducted by a…

Genome stability: Intricate process of DNA repair discovered

DNA illustration (stock image). Credit: © Design Cells / Adobe Stock An elaborate system of filaments, liquid droplet dynamics and protein connectors enables the repair of some damaged DNA in the nuclei of cells, researchers at the University of Toronto have found. The findings further challenge the belief that broken DNA floats aimlessly -- and…

Gene variants provide insight into brain, body incongruence in transgender

Genetic sequencing illustration (stock image). Credit: © ktsdesign / Adobe Stock Some of the first biological evidence of the incongruence transgender individuals experience, because their brain indicates they are one sex and their body another, may have been found in estrogen receptor pathways in the brain of 30 transgender individuals. "Twenty-one variants in 19 genes…

Altruistic babies? Infants are willing to give up food, help others

Children sharing an apple (stock image). Credit: © anoushkatoronto / Adobe Stock Altruistic helping -- the act of giving away something desirable, even at a cost to oneself -- is perhaps no more evident than when it comes to food. Human adults often respond to hungry people, whether through food banks or fundraisers, or by…

DNA extracted in museum samples can reveal genetic secrets

DNA illustration (stock image). Credit: © adimas / Adobe Stock DNA in preserved museum specimens can allow scientists to explore the history of species and humanities impact on the ecosystem, but samples are typically preserved in formaldehyde which can damage DNA and make very difficult to recover. Researchers have used a vortex fluidic device (VFD)…
