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.

Was given test for Singapore students and failed.

The publication compared ChatGPT with students who have taken the PSLE in the past three years using questions from the latest collection of past year papers that are available in bookstores.

ChatGPT received a mere 16 out of 100 points for three math papers, 21 points for the science papers, and 11 out of 20 for the English papers.

Through a phenomenon known as gravitational lensing, aliens could be transmitting signals using the sun, but a quick scan for such signals has turned up nothing.

Scientists have proposed a way that the universe could stop expanding, ending in a ‘Big Crunch’ that resets space and time as we know it.

The OVM6948 is the only ultra small “chip on tip” camera with backside illumination, which provides excellent image quality.
