Over the course of only a century, humanity has made an observable impact on the genetic diversity of the lion population. That’s the conclusion of a recently published study by Caitlin Curry and James Derr from the Texas A&M University College of Veterinary Medicine & Biomedical Sciences.

A cell in worms that transforms itself into a completely different type of cell when males mature has recently been discovered. In the cell switch, a glial cell becomes a sensory neuron, which enables the worms to improve their mating technique.

A new study by researchers at the Max Planck Institute for Ornithology suggests that the way in which DNA is packaged in retinal cells within owls' eyes is what helps them see at night.

A blood test already available to GPs in the UK is more predictive of ovarian cancer than previously thought and could also help pick up other forms of cancer, according to new research published in PLOS Medicine.

Hybridizations with wild species have made the apple genome very complex and difficult to study. A team of multi-disciplinary researchers tackled this problem by applying cutting-edge sequencing technologies and bioinformatics algorithms to assemble complete sets of both chromosomes for the domesticated apple and its two main wild progenitors.

Two scientists at the Max Planck Institute of Neurobiology developed a method in the fruit fly that marks receptor proteins in selected cells. In this way, they gained new insights into the neuronal mechanisms of motion vision. In addition, the research community receives an innovative tool to label proteins of all kinds.

A study has shown that there are seven "forms of disease" in mild COVID-19 and that the disease leaves behind significant changes in the immune system, even after 10 weeks. These findings could play a significant role in the treatment of patients and in the development of a potent vaccine.

A study involving more than 5,000 COVID-19 patients in Houston finds that the virus that causes the disease is accumulating genetic mutations, one of which may have made it more contagious.

A team of biomedical engineers has studied how human and mouse cells communicate with each other. The team discovered that the humanized tissue is physiologically integrated into single functional bone tissue which retains species-specific ultrastructural differences.

A new study finds that pancreatic cancer cells avoid starvation by signaling to nerves, which grow into dense tumors and secrete nutrients.
