Handwriting requires a combination of fine motor control and a complex set of mental skills, such as selecting, organizing, and interpreting sensory information, making it a cognitively challenging task. Because of its high ...
Phys.org / If you need to anesthetize a butterfly, here's the best way to do it
Anesthesia makes life-saving procedures as painless and stress-free as possible for the animals we love and care for. But not a lot is known about the effects of anesthesia on animals that we don't typically consider pets—like ...

A new European-led telescope could map the dusty, hidden half of the universe, all without using fossil fuels. If you have ever seen the Milky Way in the night sky, you probably noticed that it looks cloudy. That is because ...
Phys.org / Piezoelectric effect in diamond membranes challenges century-old scientific dogma
A research team in China has reported a significant piezoelectric effect in ultrathin and ultra-flexible polycrystalline diamond membranes. This pioneering discovery challenges a century-long scientific dogma that diamonds ...
Medical Xpress / Pilot trial suggests anti-inflammatory drug could help difficult-to-treat depression
Immunotherapy could be a promising new treatment option for patients with difficult-to-treat depression. This is a key finding from a University of Bristol-led pilot randomized controlled clinical trial, published in JAMA ...

Phys.org / When Mendel's rules don't apply: Mouse study reveals hidden epigenetic inheritance
Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA code itself—can also be ...
