Ancient Extra-Terrestrial rock —Geologists in France and Italy have spotted what appear to be organic molecules from outer space in 3.3-billion-year-old rocks in South Africa, according to a new study.
Organic molecules, from methane to amino acids, exist in space. Perhaps some of these molecules were brought to our own planet via carbon-containing asteroids. Scientists studying ancient rock in South Africa seem to have uncovered evidence of the oldest examples yet of these extraterrestrial molecules.

Fabric purifies water — A team of scientists in China has found a way to purify water contaminated with pharmaceuticals and personal care products (PPCPs). Their findings are published in the journal ACS Applied Materials & Interfaces.

Improvement for hearing aids — Researchers at Columbia University had the opportunity to work with epilepsy patients undergoing repeated brain surgeries to test out a new approach to improving how hearing aids work. Using data gathered from electrodes implanted directly into the volunteers’ brains, they found that their brain wave activities tended to naturally mirror the speech patterns of a specific person they were focusing on and listening to, even when other voices were competing for attention. It’s this unique behaviour of the brain that researchers believe could be the key to radically improving the effectiveness of hearing aids.

We can build you from Titanium — Titanium is a silver-coloured metal valued for its low density, high strength, and resistance to corrosion. Relatively low-cost precision 3D printing is becoming a game-changer for titanium as designers can create amazing shapes, including structural body parts.
~ Titanium is a very biocompatible metal.
Almost-transparent batteries — Scientists in South Korea have developed a transparent and flexible battery using single-layered graphene. Advances in materials science and electronics are bringing such gadgets closer to reality. Graphene, a one-dimensional layer of carbon atoms in a hexagonal arrangement, has unique electrical and optical properties, making it ideal for use in electronic displays and devices.
~ Imagine a wholly-transparent smartphone.
Electric car c1884 — Thomas Parker was a British genius inventor who revolutionised several aspects of life in England. He was once described as “the Edison of Europe” because of the things he was able to accomplish. He even built an effective electric car.
~ He had well aware how bad coal and gas were for the environment.
Ancient beers revived — A self-proclaimed beer archaeologist, Rupp has traveled the world in search of clues as to how ancient civilisations made and consumed beer. With Avery Brewing Co, he has concocted eight of them in a series called Ales of Antiquity. The brews are served in Avery’s restaurant and tasting room.

Ancient school of fish — An exquisite fossil of photographic-like quality shows nearly 260 tiny fish swimming together in what appears to be coordinated group action. The 50-million-year-old fossil is evidence that fish have been swimming together in shoals for a very long time.
~ An enduring lesson, then.
