French company Akoustic Arts has developed a directional loudspeaker called A that only one person can hear at a time – without needing headphones. A works by transposing sound frequencies, shifting audible sound into the ultrasonic realm. The resulting ultrasonic signal is then fired out like a laser beam from the A, at which point …
Imagine being able to charge your laptop, phone or tablet from a distance. That’s the promise offered by WiTricity, a new wireless charging technology developed by two professors at MIT. WiTricity uses a technique the professors first demonstrated in 2007, which makes use of natural resonant frequencies. This is the phenomenon whereby a wine glass will shatter if an opera singer hits a certain note, because …
If you fancy growing your own food but are hampered by not having a garden, you’ll love this invention from Estonia’s Natufia Labs. The Kitchen Garden is an indoor incubator that’ll let you grow herbs and vegetables inside a high-tech hydroponic cabinet with a footprint of just 590 x 580mm. It’s equipped with an array of sensors that send data about growing conditions to a smartphone app, and …
One of the biggest crowdpullers at CES (the biggest new tech showcase of the year) was this prototype of a huge robotic exoskeleton. Built by Furrion Robotics, the Prosthesis weighs more than three tonnes. The 4.2m-tall, 4.8m-long mech is operated by a human pilot, just like the AMP suits in the movie Avatar – but …
Imagine if bumping into someone in the street meant you knew everything they knew. A French team has discovered that when two slime moulds fuse together, they pool their knowledge. This knowledge is then retained by both organisms even if they’re split into two. It’s only been known for a short while that slime moulds …
Nothing ever escapes a black hole, right? Wrong. New research has revealed that Sagittarius A*, the supermassive black hole which lie the heart of the Milky Way, regularly issues forth balls of gas that can be as big as a planet. Strictly speaking, these don’t actually come from the black hole itself, because their point …
If you thought untangling your phone charger from the mass of leads and cables in your desk drawer was tricky, spare a thought for David Leigh and his team at the University of Manchester, who recently had to unpick a knot that featured eight ‘crossings’ despite measuring just 20 millionths of a millimetre across. It was entirely their own fault, mind …

If you were to travel back tens of thousands of years in time and look up, you may well see a sky full of mini moons. Researchers from the Technion-Weizmann Institute of Technology have proposed a theory suggesting that our current Moon may be the latest in a long line of moons that orbited Earth …

The grunts, barks and wahoos of baboons contain distinct vowel-like sounds similar to human speech, suggesting language may have begun to evolve 25 million years ago. After analysing 1,335 spontaneous vocalisations produced by 15 male and female Guinea baboons in different social contexts, researchers from Grenoble Alpes University in France found that baboons produce five sounds that have …

Just call it bat chat. Researchers from Tel Aviv University have managed to decipher bat calls, to find out exactly what they’re talking about. The team spent 75 days monitoring a group of 22 Egyptian fruit bats (Rousettus aegyptiacus) round-the-clock. After recording tens of thousands of calls, the researchers used a machine-learning algorithm to pick …
Let us introduce Thor, Loki, Odin and Heimdall – our microbial ancestors dating back two billion years. A team at Uppsala University, Sweden has discovered several microbes carrying genes that were previously thought to be unique to more complex life forms, including humans. The single-celled microorganisms, called archaea, were discovered in aquatic sediments collected at …

Step aside, Nanook: NASA has announced a Mars base concept that reinvents the igloo. The variable distance between Mars and Earth means astronauts may have to stay on the surface of the Red Planet for many months. That means living quarters are required to keep the crew safe from wildly varying temperatures and radiation. Dubbed …
1. A discarded banana peel is extremely slippery. The friction between the peel and a smooth floor is six times lower than between the floor and your shoe. 2. The slipperiness comes from the follicle cells on the inside of the peel. When they are crushed underfoot, they release a polysaccharide gel between the floor …
