Tiny wireless device sheds light on combating obesity — ScienceDaily

Gastric bypass surgery is sometimes the last resort for those who struggle with obesity or have serious health-related issues due to their weight. Since this procedure involves making a small stomach pouch and rerouting the digestive tract, it is very invasive and prolongs the recovery period for patients. In a new study, researchers at Texas […]

What to know before you buy an electric vehicle

Understanding the different charging levels and types will help you make a more informed decision about EV ownership. (Photo by CHUTTERSNAP on Unsplash/) Electric cars have long remained objects of fantasy, tantalizingly just out of reach for drivers who imagine the joy of whooshing silently around town, powered by electrons that were hopefully produced by […]

Bioenergetics: New features of ATP synthase

The mitochondrial ATP synthase is energy-converting macromolecular machine that uses the electrochemical potential across the bioenergetic membrane called cristae. This potential is maintained via a membrane curvature that is induced by ATP synthase assembled in dimers. The dimers shaping the bioenergetic membrane were thought to be universal across the eukaryotic organisms. Two newly published cryo-EM […]

Scientists discover virus-like particles in Bryozoa

Credit: SPbU Scientists from Russia, Austria, and the USA have discovered virus-like particles in the bacterial symbionts of Bryozoa—a phylum of colonial aquatic invertebrates—filter-feeders dominating in many bottom ecosystems. The research project was planned and supervised by scientists from St Petersburg University. Some of the virus-like […]

Pfizer vaccine works against coronavirus mutation in UK and S. Africa variants

Pfizer’s coronavirus vaccine is effective against a key mutation found in variants of the virus that are spreading faster than the original strain, according to an early study. While viruses mutate all the time, scientists worry that some of the new mutations in the novel coronavirus, specifically those in a new variant discovered in South […]

Nanoparticle vaccine for COVID-19 — ScienceDaily

Before the pandemic, the lab of Stanford University biochemist Peter S. Kim focused on developing vaccines for HIV, Ebola and pandemic influenza. But, within days of closing their campus lab space as part of COVID-19 precautions, they turned their attention to a vaccine for SARS-CoV-2, the virus that causes COVID-19. Although the coronavirus was outside […]

COVID-19 immunity could be long term

Many people who catch COVID-19 may develop long-lasting immunity to the new virus, SARS-CoV-2. (Pixaba/) People who have recovered from COVID-19 mount an immune response that persists for at least eight months, scientists reported on January 6 in the journal Science. Researchers detected multiple components of the immune system specific to defending against the novel […]

Bacteria can tell the time

Shining a light on internal clocks – the bacterium Bacillus subtilis. Credit: Professor Ákos Kovács, Technical University of Denmark Humans have them, so do other animals and plants. Now research reveals that bacteria too have internal clocks that align with the 24-hour cycle of life on Earth. The research answers a long-standing biological question and […]

Dwarf giraffes were just discovered, and they’re adorable

Adorable dwarf giraffes have been spotted for the first time, and with their graceful long necks tacked onto a set of chunky legs, they look like a mashup of mythical creatures. Researchers identified two wild giraffes that were around 9 feet (2.7 meters) tall — about half the height of the average giraffe. That diminutive […]
