Engineers crack 58-year-old puzzle on way to quantum breakthrough

A happy accident in the laboratory has led to a breakthrough discovery that not only solved a problem that stood for more than half a century, but has major implications for the development of quantum computers and sensors.In a study published today in Nature, a team of engineers at UNSW Sydney has done what a celebrated scientist first suggested...

Scientists used computer algorithms to “evolve” an organism that’s made of 100% frog DNA — but it isn’t a frog.

A manufactured quadruped measuring 650 to 750 microns in diameter — just a little smaller than the head of a pin — was built from amphibian stem cells. (Image credit: Douglas Blackiston, Tufts University)What happens when you take cells from frog embryos and grow them into new organisms that were "evolved" by algorithms? You get something that...

Scotland scientists invent groundbreaking low-emissions, recycled building brick

Scientists at Heriot Watt University in Scotland have developed the world’s first building brick that’s made from 90% recycled construction and demolition waste. The K-Briq uses less than one-tenth of the energy in its manufacture, creates one-tenth of CO2 emissions of a traditional fired brick, and can be made in any color.

China’s lunar rover travels 367 meters on moon’s far side

China's lunar rover Yutu 2 (Jade Rabbit 2) has driven 367.25 meters on the far side of the moon to conduct scientific exploration. Both the lander and the rover of the Chang'e 4 probe ended their work for the 14th lunar day on Saturday (Beijing Time), and switched to dormant mode for the lunar night, according to the Lunar Exploration...

Taiwan researchers successfully extract sample of coronavirus

Taiwanese researchers have successfully extracted a sample of the novel coronavirus (2019-nCoV), which could eventually lead to the development of a vaccine, Health and Welfare Minister Chen Shih-chung (陳時中) said Friday. The virus, which was first detected in the Chinese city of Wuhan last December, has been declared a global emergency by the World Health Organization. As of Sunday morning, China...

scientists create first “living robot” that is neither bot nor beast

A remarkable combination of artificial intelligence (AI) and biology has produced the world’s first “living robots”. A research team of roboticists and scientists has published their recipe for making a new life form called xenobots from stem cells. The term “xeno” comes from the frog cells (Xenopus laevis) used to make them. One of the researchers described the creation as “neither...

FUTMinna research group gets £155,465 AI grant

The Advanced Engineering Innovation Research Group (AEIRG) of the Federal University of Technology, Minna (FUTMinna), has won the Royal Academy for Engineering Research grant for artificial intelligence (AI) for clean energy. The grant valued at £156,465 will enable the university to build capacity in artificial intelligence and clean energy in order to address societal problems. The award letter signed by AEIRG’s...

Pair of Civil Servants Rewrite Quantum Mechanics in Their Spare Time

A pair of civil servants solve a quantum mechanics problem that had bothered them since they were students. As students, Jussi Lindgren and Jukka Liukkonen had found one element of their quantum mechanics lectures unsatisfying. “When we were taught physics, there were some fundamental elements you were told were true, and you had to accept they were true without it...

China’s first electric ship conducts trial operation

China on Friday conducted a trial operation on a first all-electric passenger ship built by the China State Shipbuilding CorpJunlyu was the first electric ship weighing above 1,000 tonnes to sail the Yangtze, River, China’s longest waterway.It took two years to build the vessel by altering an oil-powered ship.With powerful lithium batteries, the 53-metre-long ship can carry...

HARMATTAN SAFETY

WHAT IS HARMATTAN?  The Harmattan is a cold-dry and dusty trade wind, blowing over the West African subcontinent. This northeasterly wind blows from the Sahara Desert into the Gulf of Guinea between the end of November and the middle of March. It consists of fine dust particles between 0.5 and 10 micrometres.
