Ribosomes are the tiny molecular machines found in all cells that translate mRNA into the amino acid chains that fold into functional proteins. Synthetic biologists have been making considerable progress in engineering yeast or bacteria to produce various chemicals, including fuels, drugs and fabrics. However, a new study by a multi-university team of chemists has …
Asteroid Itokawa, as viewed by the Hayabusa spacecraft, is a peanut-shaped S-type asteroid with a diameter of around 1,100 feet that rotates once every 12 hours. Recently, researchers at the University of Arizona Lunar and Planetary Laboratory made an exciting discovery: they found tiny salt crystals within a sample from the asteroid, indicating the presence …

Unfortunately, it is unlikely that one of the trees will survive, according to park officials and tree enthusiasts. These trees are estimated to be at least 500 …
(a) Boron vacancy defect in hexagonal boron nitride. The vacancy acts as an atom-sized quantum sensor for magnetic field measurements. The magnetic field-sensitive quantum sensor behaves like a nano-sized “magnetic needle”. (b) Photoluminescence of a quantum sensor nanoarray. By analyzing the change in the photoluminescence intensity in response to microwaves, the researchers measured the magnetic …
Credit: CC0 Public Domain Imagine being a bumblebee, with the ability to see a vibrant world of colors and scents. Bumblebees possess a keen sense of sight, allowing them to distinguish UV and most colors except red, and three separate simple eyes for detecting polarized light. In addition, their sense of smell is approximately 100 …
An ancient mystery has been solved as the oldest known footprint of Homo sapiens has been discovered on South Africa’s Cape south coast. The footprint is estimated to be 153,000 years old, making it the oldest ever attributed to our species. This new discovery underscores the fact that early anatomically modern humans survived and thrived …
Schematic workflow of bioink preparation and bioprinting process of E. coli MG1655 biofilms. An inoculated gelatin-alginate based hydrogel was pulled into a syringe. Biofilm was grown on piston while being incubated upside down. Three syringes were pooled and transferred into a cartridge for bioprinting. If required, prints can be crosslinked post-printing with CaCl2. Credit: Biofabrication …

It has been suggested that regulating these digital channels could prevent the transmission of diseases, which are capable of jumping from animals to humans. With the likes of Ebola and COVID-19 causing such …

Revealing three main coping mechanisms, ‘active’, ‘expressive’ and …
Director Steven Spielberg released the film “Jurassic Park” in June 1993, which sparked a wave of technological change in filmmaking while simultaneously reigniting popular interest in dinosaurs. Based on Michael Crichton’s novel, the film franchise spawned five blockbuster sequels as well as various spin-off games, toys, novels, and multiple animated television shows. Its plot centers …
