Robotics: The future of healthcare

Around 2007, a young surgeon stood in a conference hall in Orlando, Florida, the US staring at a magnificent robot operating on a human body. It was then that he decided what he wanted to do — become a robotic surgeon.

Meet the 'zombie star' that survived a supernova blast

Astronomers have observed in a relatively nearby galaxy a star that not only survived what ordinarily should have been certain death - a stellar explosion called a supernova - but emerged from it brighter than before the blast.

Chinese spacecraft acquires images of entire planet of Mars

An uncrewed Chinese spacecraft has acquired imagery data covering all of Mars, including visuals of its south pole, after circling the planet more than 1,300 times since early last year, state media reported on Wednesday.

A composite image shows the star-forming region called 30 Doradus, also known as the Tarantula Nebula in this undated handout picture. The background image, taken in the infrared, was captured by the HAWK-I instrument on ESO's Very Large Telescope (VLT) and the Visible and Infrared Survey Telescope for Astronomy (VISTA) and shows bright stars and light, pinkish clouds of hot gas. The bright red-yellow streaks superimposed on the image come from radio observations taken by the Atacama Large Millimeter/submillimeter Array (ALMA), revealing regions of cold, dense gas that have the potential to collapse and form stars.

So long, Internet Explorer. The browser retires today

Internet Explorer is finally headed out to pasture. As of Wednesday, Microsoft will no longer support the once-dominant browser that legions of web surfers loved to hate — and a few still claim to adore. The 27-year-old application now joins BlackBerry phones, dial-up modems and Palm Pilots in the dustbin of tech history.

Astronomers ponder 'cosmic mystery' over powerful radio wave bursts

Powerful bursts of radio waves emanating from a distant dwarf galaxy that were detected using a massive telescope in China are moving scientists closer to solving what one called a "cosmic mystery" that has lingered for years.

Dusty demise for NASA Mars lander in July; power dwindling

Dusty demise for NASA Mars lander in July; power dwindling

A NASA spacecraft on Mars is headed for a dusty demise. The Insight lander is losing power because of all the dust on its solar panels. NASA said Tuesday it will keep using the spacecraft's seismometer to register marsquakes until the power peters out, likely in July. Then flight controllers will monitor InSight until the end of this year, before calling everything off.

This artist’s impression shows a two-star system, with a white dwarf (in the foreground) and a companion star (in the background), where stellar explosions called micronovae may occur. The white dwarf steals materials from its companion, which is funnelled towards its poles. As the material falls on the hot surface of the white dwarf, it triggers a micronova explosion, contained at one of the star’s poles.

Surprised astronomers find new type of star explosion - a micronova

Astronomers have detected a previously unknown type of stellar explosion called a micronova involving thermonuclear blasts at the polar regions of a type of burned-out star called a white dwarf after it has siphoned material from a companion star.
