The world’s biggest X-ray laser called European XFEL has reached the last major milestone, its first X-ray laser light, ahead of its official opening in September this year.

Most of the 3.4-kilometer-long facility is located in underground tunnels. It produced its first X-ray laser light with a wavelength of 0.8 nm – roughly five hundred times shorter than that of perceptible light.

At the very first lasing, the European XFEL produced laser with a repetition rate of one pulse per second that will later boost to a whopping 27 000 per second.

Elon Musk-led SpaceX on Wednesday announced its plans to launch thousands of small satellites starting in 2019 to establish a global broadband internet constellation.

Patricia Cooper, vice president of satellite government affairs at SpaceX, told the U.S. Senate’s Committee on Commerce, Science & Transportation that the private-sector firm wanted to launch 4,425 small satellites to low Earth orbit starting in 2019.

The satellites, all of which would be launched in phases on Falcon 9 rockets, will be fully deployed by 2024.

A team of researchers at MIT’s Computer Science & Artificial Intelligence Lab claimed to have developed a device capable of measuring the walking speeds with unprecedented accuracy, without requiring the individual to wear an on-body measurement device.

The new device, dubbed WiGait, can measure the walking speeds of people with an accuracy of 95 to 99 per cent using wireless signals.

Elon Musk-led SpaceX is all set to launch a classified spacecraft for the National Reconnaissance Office (NRO) into Earth’s orbit this Sunday (April 30), officials confirmed.

A Falcon 9 rocket carrying the spacecraft is scheduled to lift off sometime between 7 a.m. and 9 a.m. EDT or 1100 to 1300 GMT from Florida’s Kennedy Space Center. The planned launch will mark the fifth of nearly two dozen launched scheduled to fly this year.

The launch will also break United Launch Alliance’s (ULA’s) ten-year monopoly on launching military and national security satellites.

A new study has attempted to resolve the mysterious phenomenon by which neatly and securely tied shoelaces untie, particularly when the wearer walk fast or run.

Researcher Oliver O'Reilly said his shoelaces had been coming untied daily for more than four decades but he never thought much about it. But, around a decade back, when his daughter Anna was learning how to tie her shoes, he decided to find out why shoelaces get untied on their own.

In wake of reports that President Vladimir Putin’s administration is training a ‘robot army’ to shoot using guns with both hands, Russia has denied that the Terminator-like army would jeopardize humans.

In December last year, reports emerged that the android-based robots known as Final Experimental Demonstration Object Research (FEDOR) were being trained for exploring space. But, new reports suggested that robots are being trained to shoot guns.

A recently published shocking news about a couple from Mississippi having issues in conceiving a child finding out that they were twins, has turned out to be a fake news. The news was shocking and more than 30,000 people shared it on Facebook. Major outlets including Daily Mail, Mirror and The Sun published the story. The news was first reported by Mississippi Herald and identity of the couple was kept a secret. The report added that a couple in Mississippi was informed by their doctor that they were twins.

Water Harvesting from air sounds like a difficult idea to implement but a research team from MIT and UC Berkeley has successfully developed a prototype water harvester which can collect water from air with as low at 20-30 percent humidity. The technique can help in dealing with water crisis in many regions across the world and research team added that water harvested with this technique is pure and drinkable. The research team has presented a device based on porous metal-organic framework-801 [Zr6O4(OH)4(fumarate)6] which is powered by natural sunlight.

Amazon CEO Jeff Bezos offered a sneak peak to Blue Origin’s space tourism capsule and what passengers for space tourism can expect. The New Shepard spaceship is already on its nationwide tour and the design of capsule suggests that every seat will be a window seat. The New Shepard spaceship could take tourists for its first journey as early as next year. The spaceship will take tourists to the edge of space but Blue Origin has still not revealed the cost of ticket for this amazing journey.
