Dr. Tamar Gutnick, first author and former postdoctoral researcher in the Physics and Biology Unit at the Okinawa Institute of Science and Technology (OIST), said, “If we want to understand how the brain works, octopuses are the perfect animal to study as a comparison to mammals. They have a large brain, an amazingly unique body, and advanced cognitive abilities that have developed completely differently from those of vertebrates.”
“Octopuses have eight powerful and ultra-flexible arms, which can reach anywhere on their body. If we tried to attach wires to them, they would immediately rip it off, so we needed to get the equipment out of their reach by placing it under their skin.”
Protons and neutrons are held together by the strong force: with 3 colors and 3 anticolors. So why are there only 8 gluons, and not 9?

The pros and cons of moonlighting—taking up an extra job in addition to full-time employment—are hotly debated. But in biology, moonlighting is not uncommon, as individual proteins often perform multiple functions. For many years, scientists knew that the Unusual Floral Organ (UFO) protein seems to do some moonlighting.
Based on the protein’s structure, its role in plants is thought to target proteins for destruction. But it also works with the Leafy (LFY) protein to aid flower formation. A team of scientists from France has now shed light on how this protein performs two roles.
“It’s safe, economical and gentle for people,” Iwaya told reporters. “The idea is to make space tourism for everyone.” He said he wants to “democratize space.”
The company, Iwaya Giken, based in Sapporo in northern Japan, has been working on the project since 2012 and says it has developed an airtight two-seat cabin and a balloon capable of rising up to an altitude of 25 kilometers (15 miles), where the curve of the Earth can be clearly viewed. While passengers won’t be in outer space—the balloon only goes up to roughly the middle of the stratosphere—they’ll be higher than a jet plane flies and have an unobstructed view of outer space.
Calcium carbonate is an impressive material, in that it combines strength, light weight and porosity. Scientists have devised a new bacteria-based method of 3D-printing the substance, for use in applications such as bone repair and coral reef restoration.
First of all, this isn’t the first time we’ve heard about the 3D-printing of calcium carbonate objects.
Earlier approaches have involved extruding a gel containing mineral particles, which subsequently dries and hardens. Some of the resulting items have been rather soft and fragile, however, or they’ve shrunk as they dried, creating cracks and causing their shape to change.
Armed with tools and repair guides from hardware repair advocacy firm iFixit, a user can remove and replace the phone’s back cover, battery, screen and charging port.
Adam Ferguson, head of product marketing at HMD Global, said that this process would cost on average 30% less than replacing an old phone with a new one.
Smartphone companies are increasingly working to make phones last for longer amid pressure from regulators to make electronics devices more sustainable.
An Austrian and Spanish team demonstrated that a process can be ‘rewound’ to restore the components of an atom to their previous state.
Protein engineers are drawing on rapidly evolving machine learning tools, deep reservoirs of data, and the structure-predicting firepower of AlphaFold2 to pursue more sophisticated de novo protein designs.
