Nanorobots Capable of Folding DNA can Replicate Indefinitely

Robotics, Science /

Researchers have showcased a programmable nanoscale robot constructed from a few DNA strands, which can capture other DNA fragments and assemble them to produce new UV-welded nanomachines, including duplicates of itself. In fact, the nanorobots, as reported by New Scientist, are constructed using only four DNA strands and have dimensions of approximately 100 nanometers, allowing […]

Sleep Boosts Memory but Can also Implant False Memories

Neuroscience, Science /

A group of psychologists from the University of York in the U.K. has discovered through experiments that sleeping after studying can solidify memories. However, as outlined in their publication in the journal Royal Society Open Science, sleep can also occasionally result in the formation of false memories. Recent research has highlighted the fallibility of human

Electric Eel Shocks Transfer Genes to Nearby Animals

Biology, Genetics /

A recent investigation indicates that the electrical discharge from an electric eel is potent enough to facilitate the transfer of genetic material from the surroundings into the cells of neighboring animals. In laboratory conditions, electroporation refers to applying an electric field to cells to enhance the permeability of their cell membrane. This enables the introduction

Home Saliva Tests: A Potential Alternative to Daily Finger Pricks for Diabetics

Healthcare, Medicine, Science /

For people with diabetes, having to do painful daily finger-prick blood tests is a common and uncomfortable experience. However, scientists created a sample device for home use that checks blood sugar levels using saliva instead. We already knew that the amounts of glucose (and some other biomarker substances) in saliva are linked to those in
