A chunk of ice half the size of Jamaica which is breaking away from West Antarctica is now attached to its parent ice shelf just by a thread, scientists reported Friday.
.Covering 5,000 square kilometres (1,900 square miles) and nearly 100 storeys deep, the formation is poised to snap off from Larsen C ice shelf, creating “one of the largest icebergs ever recorded,” the researchers said in a statement.
A widening rift running the length of the finger-shaped, 350-metre (1150-feet) -thick ice block grew 10 kilometres (six miles) longer some time during the last three weeks, satellite images revealed.
“The rift is likely to break off in the next few months—if it doesn’t, I’ll be amazed,” said Adrian Luckman, a professor at Swansea University in Wales, and leader of Britain’s Project Midas, which tracks changes in West Antarctic ice formations.
“It’s so close to calving that I think it’s inevitable,” he told AFP.

Researchers have found a way to trigger the innate, but previously hidden, ability of graphene to act as a superconductor – meaning that it can be made to carry an electrical current with zero resistance.
.
The finding, reported in Nature Communications, further enhances the potential of graphene, which is already widely seen as a material that could revolutionise industries such as healthcare and electronics. Graphene is a two-dimensional sheet of carbon atoms and combines several remarkable properties; for example, it is very strong, but also light and flexible, and highly conductive.
Since its discovery in 2004, scientists have speculated that graphene may also have the capacity to be a superconductor. Until now, superconductivity in graphene has only been achieved by doping it with, or by placing it on, a superconducting material – a process which can compromise some of its other properties.

A team of researchers with members from Iceland, the U.K. and the Netherlands has found a genetic factor that plays a role in how much education a person might attain over their lifetime and that the factor is becoming less common. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they analyzed genomic information in a national database in Iceland and what it showed.
.
Prior efforts have demonstrated that the more education a person has, the fewer offspring they are likely to produce. This has caused some concern among social scientists, as it suggests that we as a species might be evolving to become less intelligent beings. In this new effort, the researchers sought to determine if there might be a way to see this process at work.

Is there anybody out there? The question of whether Earthlings are alone in the universe has puzzled everyone from biologists and physicists to philosophers and filmmakers. It’s also the driving force behind San Francisco State University astronomer Stephen Kane’s research into exoplanets—planets that exist outside Earth’s solar system.
As one of the world’s leading “planet hunters,” Kane focuses on finding “habitable zones,” areas where water could exist in a liquid state on a planet’s surface if there’s sufficient atmospheric pressure. Kane and his team, including former undergraduate student Miranda Waters, examined the habitable zone on a planetary system 14 light years away. Their findings will appear in the next issue of Astrophysical Journal in a paper titled “Characterization of the Wolf 1061 Planetary System.”
“The Wolf 1061 system is important because it is so close and that gives other opportunities to do follow-up studies to see if it does indeed have life,” Kane said.

What scientific discoveries will 2017 bring? What technological innovations? Probably not time travel — or time-shares on Mars. But no one really knows for sure, and when we asked some of the biggest names in in science and technology to share their predictions for the coming year, there was a bit of pushback.
“I normally don’t make predictions for anything less than two trillion years in the future,” Arizona State University cosmologist Lawrence Krauss told NBC MACH. It’s easier to make predictions that far out, he added jokingly, when “no one will be around to check them.”
Ultimately, Krauss came through with some fascinating forecasts. Read on to see them, along with predictions from legendary astronaut Buzz Aldrin and nine more thought leaders in science and tech (the submissions have been lightly edited).

If you’re an innovative person with ideas about how best to deal with your bodily functions while wearing a spacesuit, then NASA wants to hear from you! The agency is currently soliciting entries in its aptly titled Space Poop Challenge, posted on the website HeroX, to “source a system that routes and collects human waste away from the body” for “fully-suited astronauts.”
What’s more, it pays. The innovator with the winning design gets $30,000.
Right now, astronauts use space toilets when they’re out of their suits and diapers when they need to wear their spacesuits during launch and entry, but diapers are usually only worn for a matter of hours. They’re also uncomfortable, and keeping waste next to your body for long periods of time can lead to irritation and infection.

Famed theoretical physicist Stephen Hawking has some grim news for humanity: We have 1,000 years to get off Earth or we’re totally screwed.
The 74-year-old Hawking delivered a speech on Tuesday at , reported the Daily Express, in which he said “I don’t think we will survive another 1,000 years without escaping beyond our fragile planet.” Hawking reportedly said that humans are speeding towards the end of our time on Earth by destroying and using up its resources — and eventually, it will be impossible for us to continue living here.

The launch was 3:20 p.m. EST Thursday, which was early Friday morning at the Baikonur cosmodrome in Kazakhstan.

At 56, astronaut Peggy Whitson is a lot younger than John Glenn was when he flew in a space shuttle at 77, but when Whitson launched Thursday with two other crew members toward the International Space Station she became the oldest female astronaut in the world to fly into space.

A millisecond is a thousandth of a second, and a nanosecond is a billionth of a second, but there’s another measurement of time that makes both of them look slow.
Scientists have for the first time been able to measure something in a zeptosecond, or a trillionth of a billionth of a second.
Laser physicists in Munich fired an extreme ultraviolet light pulse onto a helium atom to excite the electrons, causing one to break free ― a process called photoemission. At the same time, they shot an infrared laser pulse to detect the electron as it left the atom.
That’s when it happened.
