Surgeon used 5G network to operate remotely on animal

Technology
A doctor in China has become the first to perform remote control surgery over a super-fast 5G network. The surgeon, who manipulated two robotic arms, was 30 miles from an operating theatre in Fujian province.During the procedure, he removed a laboratory animal's liver, the South China Morning Post reported.The 5G system, which is said to be at least 10 times as fast as current networks, and perhaps even up to a hundred times, has a lag time of only 0.1 seconds.That meant the delay between the surgeon's movements, and the robot in the theatre, was short enough to avoid potentially dangerous mistakes.In future, it is hoped such technology will enable surgeons to work remotely in war zones and disaster areas.It will also allow specialists from large hospitals to assist more ju...

Total lunar eclipse meets supermoon Sunday night

Total lunar eclipse meets supermoon Sunday night

Technology
Here comes a total lunar eclipse and supermoon, all wrapped into one. The moon, Earth and sun will line up this weekend for the only total lunar eclipse this year and next. At the same time, the moon will be ever so closer to Earth and appear slightly bigger and brighter than usual — a supermoon. "This one is particularly good," said Rice University astrophysicist Patrick Hartigan. "It not only is a supermoon and it's a total eclipse, but the total eclipse also lasts pretty long. It's about an hour." The whole eclipse starts Sunday night or early Monday, depending on location , and will take about three hours. It begins with the partial phase around 10:34 p.m. EST Sunday. That's when Earth's shadow will begin to nip at the moon. Totality — when Earth's shadow completely blank...
Desalination's leftovers may negatively affect oceans and ecosystems

Desalination's leftovers may negatively affect oceans and ecosystems

Technology
This is an Inside Science story. About 700 million people worldwide lack reliable access to fresh water, a number which might grow due to population growth and climate change. This has pushed many nations to look to new, untapped water sources. One popular solution has been the construction of plants to remove salt from water sources such as seawater. However, new research from the United Nations University Institute for Water, Environment and Health in Canada is warning that a byproduct of these desalination plants -- super-salty, potentially toxic brine -- is being produced in large quantities and that it could pose serious environmental threats. There are now almost 16,000 desalination plants in the world. Although the majority of plants worldwide are located in the Middle East and ...
