Streak of Light in Western US sky causing Social Media Buzz was Russian Space Debris, say Military officials

People in three Western states saw a mysterious fireball entering earth’s atmosphere on Tuesday. The light streak not only lighted up the sky, but also social media. Some people said it was a meteor, but US Military officials believe it was debris from a Russian rocket.

The officials said the light witnessed by many people over an apartment complex in Las Vegas earlier came from rocket debris while entering the earth’s atmosphere. They also said that people should not believe rumors suggesting that the light was a meteor.

Oso, Washington has faced Landslides once every 500 years, unveils Calibrated surface dating method

Oso has faced Landslides once every 500 years, unveils Calibrated surface dating method

Cancelling earlier beliefs that Oso, Washington, had witnessed a series of large landslides thousands of years ago, researchers using new dating method have concluded landslides have been continuing in recent history.

In March 2014, much of Oso was buried in the large, fast-moving landslide that was the deadliest landslide in the US history. Geologists from University of Washington said that they have come up with a new method to date all the earlier landslides at a particular location.

UCLA Researchers Create Super-Strong yet Light Structural Metal with Extremely High Specific Strength

UCLA Researchers Create Super-Strong yet Light Structural Metal with Extremely High Specific Strength

Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have done remarkable job by creating a super-strong yet light structural metal with extremely high specific strength and modulus. The new metal made of magnesium infused with dense silicon carbide nanoparticles could have significant implications in making lighter airplanes, spacecraft, and cars, mobile electronics and many more. It could also be used to help improve fuel efficiency and biomedical devices.

Strong and Light-weight metal developed by UCLA Research Team Using Ceramic Nanoparticles

UCLA researchers have developed a new metal by combining magnesium and ceramic silicon carbide nanoparticles which has record-breaking strength to weight ratio. The lightweight metal has extremely high specific strength and modulus. It can be used as light structural metal. Structural metals are used as load-bearing metals in structures and vehicles. The research team used magnesium as it is the lightest structural metal.

California Desperately In Need Of Early Warning System for Earthquakes

California Desperately In Need Of Early Warning System for Earthquakes

The members of the US Congress said California presently is under high risk to be hit by an earthquake. This is the time when it feels need of having a system that could guide people to reach safer place, and Californians presently are in high need of any such system to help them save themselves from mega earthquake.

Presently, a prototype system has been developed by the researchers at the California Institute of technology (Caltech) and the congress members are asking president Obama to fund the project.

World’s busiest ice road is running late this year

World’s busiest ice road is running late this year

In the remote areas of Canada’s north, an icy highway builds up atop frozen lakes every winter and tundra works as a supply lifeline to far away diamond mines that bustles with traffic for months prior to melting away in the spring.

The busiest ice road of the world is running late this year. The ice formation on the Tibbitt to Contwoyto Winter Road has received a setback due to unseasonably warm weather. The name of the road has been given after the first and last of hundreds of lakes on the route.

Immediate fossil fuels elimination is a way to achieve Paris global warming targets, scientists say

Immediate fossil fuels elimination is a way to achieve Paris global warming targets, scientists say

Scientists said that if governments are serious regarding the global warming targets adopted by them in Paris, then there are two options. One is immediate elimination of fossil fuels and second is to look for ways to undo their harm on the climate system in the coming time.

The first one is politically impossible as the world still engages in using coal, oil and natural gas, leaving the option of a significant atmosphere cleanup later this century.

Experts think reusable rockets may not be as cheaper as Space X thinks

Experts think reusable rockets may not be as cheaper as Space X thinks

Space X has always believed that reusability of rockets can prove as a cost-saver for the private spaceflight industry. Now, it has even landed a rocket after launching it in space. But experts have a question as whether rocket reusability is that cost-effective as prompted by Space X.

Elon Musk has shared some facts that it takes $60 million to make Falcon 9 and $200,000 to fuel it. He believes that reusing rockets can lower these costs, which as per experts, is not exactly correct. Firstly, Space X needs to be sure that it’s returned rockets are able to fly again.

NASA Puts Next Mission to Mars on Hold for Indefinite Time

NASA Puts Next Mission to Mars on Hold for Indefinite Time

Deep space missions or any mission beyond earth always involve high risk and efforts. NASA was also planning one such mission to Mars, but it has now put the mission on hold for an indefinite period.

Sources with knowledge about the matter said that the decision to cancel the new Mars lander, named InSight, was taken after agency engineers were unable to repair a major leak, which involves key scientific instruments.

Researchers capture New Caledonian crows making and using tools

Researchers capture New Caledonian crows making and using tools

Crows are intelligent and have been able to survive in diverse and difficult situations. Past researchers have proved that crows effectively use many tools. However, a technologically advanced species of crows, the New Caledonian crows, have been captured on camera making tools which they used for foraging. New Caledonian crows were captured in an interesting video by biologists while they were making hook-shaped tools.
