Brain’s stem cells slow ageing in mice
26th July 2017 | nature.com | Tech

Stem cells in the brain could be the key to extending life and slowing ageing. These cells — which are located in the hypothalamus, a region that produces hormones and other signalling molecules — can re­invigorate declining brain function and muscle strength in middle-aged mice

Lasers reactivate ‘lost’ memories in mice with Alzheimer’s
26th July 2017 | newscientist.com | Tech

A chance to remember? Forgotten memories have been reawakened in mice with Alzheimer’s disease, suggesting that the condition may not actually destroy our memories, but instead impair our ability to recall them.

It has long been assumed that Alzheimer’s disease completely erases memories. The condition involves clumps of proteins known as amyloid plaques and tau tangles accumulating in the brain, where they are thought to destroy the neurons that store our memories.

A robot delivered my dinner
25th July 2017 | theverge.com | Tech

It rides along pavements, crosses roads, and avoids driving into humans, and can travel up to three miles at 4 mph. The robot is part of a trial by Starship Technologies, a company created by two Skype co-founders. Starship is developing self-driving robotic delivery vehicles, but the current robot isn’t autonomous just yet.

We’re always hearing how robots are going to take our jobs, but there might be a way of preventing that grim future from happening: by becoming workplace cyborgs first.

Energy-harvesting bracelet could power wearable electronics
25th July 2017 phys.org | Tech

Researchers have designed a bracelet that harvests biomechanical energy from the wearer’s wrist movements, which can then be converted into electricity and used to extend the battery lifetime of personal electronics or even fully power some of these devices.

This New Material Could Let Phones And Electric Cars Charge in Seconds

Whales, sharks, butterflies and lotus leaves might together hold the secret to saving the shipping industry millions and help save the planet, according to a marine biologist.

Genetically Engineered Yeast Soak Up Heavy Metal Pollution
23rd July 2017 | acsh.org | Animal Life, Earth, Tech

Environmental contamination with heavy metals is often the result of various types of industrial processes. Because heavy metals can be dangerous to humans and other wildlife, contaminated sites need to be cleaned up. This isn’t easy. Chemical extraction methods can introduce different types of pollutants into the environment.

Give robots an ‘ethical black box’ to track and explain decisions, say scientists
22nd July 2017 | theguardian.com | Tech

As robots start to enter public spaces and work alongside humans, the need for safety measures has become more pressing, argue academics

Robots should be fitted with an “ethical black box” to keep track of their decisions and enable them to explain their actions when accidents happen, researchers say.

Buzz of drones is more annoying than any other kind of vehicle
22nd July 2017 | newscientist.com | Tech

Amazon, UPS, Domino’s Pizza and other companies planning drone delivery services may be heading for discord. A preliminary NASA study has discovered that people find the noise of drones more annoying than that of ground vehicles, even when the sounds are the same volume.

This 3D-Printed Human Heart Can Do Everything a Real One Can
22nd July 2017 futurism.com | Tech

Soft robotics and 3D printing have allowed a team of researchers from Switzerland to develop an artificial heart that works like the real thing. This proof of concept design was successfully tested in the lab, but it may take a while before it will be ready.

Scientists manipulate light to make flat surfaces appear as 3-D objects
22nd July 2017 phys.org | Tech

Scientists have created new 2-D nanostructured surfaces which appear as realistic 3-D objects – including shading and shadows – using cutting edge nano-engineering.

The research was carried out by King’s College London alongside Rheinische Friedrich-Wilhelms-Universität Bonn, and is published in the American Chemical Society journal Nano Letters.

Fly Trapped in a 3D Printed Block Is a 21st Century Fossil
22nd July 2017 gizmodo.com | Tech

Millions of years ago, unlucky animals settled in the sticky resin of trees, only to be trapped and preserved until we humans found them. Fossils of the distant future, however, will probably be a whole lot weirder than bugs in tree sap.

Robotic landers could start mining the moon as early as 2020
19th July 2017 | newscientist.com | Space, Tech

A permanent robotic mining outpost on the moon could be on the cards as early as 2020. The Florida-based company Moon Express has raised over $45 million in funding for three expeditions that will culminate in a mission to mine moon rocks and return them to Earth.
