Scientists behind a major study that claimed the Earth's oceans are warming faster than previously thought now say their work contained inadvertent errors that made their conclusions seem more certain than they actually are.

Deadly radiation from the cosmos, potential vision loss, and atrophying bones are just some of the challenges scientists must overcome before any future astronaut can set foot on Mars, experts and top NASA officials said Tuesday.

The awards are given in the field of field of Engineering and Computer Science, Humanities, Life Sciences, Mathematical Sciences, Physical Sciences and Social Sciences.

The biggest ever robot exercise in the history of the British army got underway Monday.

Some 78 million miles from Earth, alone on the immense and frigid Red Planet, a robot the size of a small 4x4 wakes up just after sunrise. And just as it has every day for the past six years, it awaits its instructions.

NASA is planning to send small devices containing human cells in a 3D matrix -- known as tissue chips or organs-on-chips -- to the International Space Station (ISS) to test how they respond to stress, drugs and genetic changes.

A team of researchers has developed a portable and low-cost mobile diagnostic tool, utilising a cellphone and nanotechnology, that can detect HIV viruses and monitor their management in resource-limited regions.

India's vaccination coverage to prevent rotavirus infection, a leading cause of severe diarrhoea in young children, was the lowest among the 15 countries which introduced it last year, a new report said Friday. It also pointed out that India lost over 2.6 lakh children under five years from pneumonia and diarrhoea in 2016.

Parker Solar Probe, NASA's historic mission to solve the mysteries of the Sun, is alive and well after skimming by the Sun at just 15 million miles from its surface. This is far closer than any spacecraft has ever gone -- the previous record was set by Helios B in 1976 and broken by Parker on October 29 -- and this manoeuvre has exposed the spacecraft to intense heat and solar radiation in a complex solar wind environment, NASA said in a statement on Thursday. On November 5, the spacecraft made the closest approach, called perihelion. Parker Solar Probe reached a top speed of 213,200 miles per hour, setting a new record for spacecraft speed. At this distance, the intense sunlight heated the Sun-facing side of Probe's heat shield, called the Thermal Protection System, to about 820 degrees Fahrenheit.

A painting of an animal in an Indonesian cave dates from at least 40,000 years ago, making it the world's oldest piece of figurative art, new research has shown.

NASA's Hubble Space Telescope has captured a formation of galaxies that looks like a smiling face, said the US space agency.

South African researchers say they have made bricks using human urine in a natural process involving colonies of bacteria, which could one day help reduce global warming emissions by finding a productive use for the ultimate waste product.

Europe's Airbus said on Friday it had delivered the "powerhouse" for NASA's new Orion Spaceship that will take astronauts to the Moon and beyond in coming years, hitting a key milestone that should lead to hundreds of millions of euros in future orders.

NASA's Dawn spacecraft has gone silent, ending an 11-year-old historic mission to explore the two largest bodies in the main asteroid belt, Vesta and Ceres, the US space agency said.
