NASA Is Planning To Capture An Asteroid And Put It In Orbit Around The Moon

UCLA researchers create exceptionally strong and lightweight new metal

Los Angeles CA (SPX) Dec 31, 2015 A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal with extremely high specific strength and modulus, or stiffness-to-weight ratio. The new metal is composed of magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles. It could be used to make lighter airplan Full article

Using copper to prevent the spread of respiratory viruses

New research from the University of Southampton has found that copper can effectively help to prevent the spread of respiratory viruses, which are linked to severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).

Futuristic Simulation Finds Self-Driving “Taxibots” Will Eliminate 90% Of Cars, Open Acres Of… — The Ferenstein Wire

A fascinating new simulation finds that self-driving cars will terraform cities

A fascinating new simulation finds that self-driving cars will terraform cities:90% of cars will be eliminated, acres of land will open up, and commute times will drop 10%. A team of transportation scientists at the Organization for Cooperation and Development took data on actual trips in Lisbon, Portugal and looked at how a fleet of self-driving, shared “taxibots” would change city landscape [PDF].

We need to move to large scale implementation as soon as the technology is good enough

These are the Most Incredible Photos Shot by NASA’s Cassini Probe

The Cassini space probe has captured its fair share of eye-popping photos since launching in 1997 and arriving in Saturn’s orbit in 2004. Here’s a collection of some of Cassini’s most remarkable photographs. Many of them were compiled by Reddit user I_Say_I_Say, and others were featured here before or obtained from NASA’s website: You can find a massive collection of Cassini’s photos in the mission gallery on NASA’s website.Thanks Petapixel

Another Station Upgrade:

Spacewalkers Jeff Williams and Kate Rubins to install new TV cameras 

On Thursday, Sept. 1, U.S. astronauts Jeff Williams and Kate Rubins will conduct the station’s 195th American spacewalk. As part of their activities, the pair will install the first of several enhanced high-definition television cameras that will monitor activities outside the station, including the comings and goings of visiting cargo and crew vehicles

Working on the station’s backbone, or truss, Williams and Rubins will retract a thermal radiator that is part of the station’s cooling system. 

As was the case for their first spacewalk together on Aug. 19, Williams will be designated as extravehicular crew member 1 (EV1), wearing a spacesuit with a red stripe, while Rubins will be EV2, wearing a suit with no stripes.

Watch LIVE!

Coverage of the spacewalk begins at 6:30 a.m. EDT on Thursday, Sept. 1; with the spacewalk scheduled to begin at 8:05 a.m. EDT. Stream live online HERE.

Where did the stars go?

One day, you find time to get out of the clutches of your work life and you decide to gaze at the stars. 

Something which you used to do when you were a kid. 

But the city life with all its glory has diverted you to other ‘fun’ things.

But to your amazement you find that the density of stars has drastically decreased.

‘That’s preposterous’- you say to yourself. That can’t be true.

You are positive that it has something to do with you aging.

You decide to go to your eye doctor and do a thorough check up. The doctor concludes that your eye sight is perfect.

You are delighted,  knowing that your eye sight is perfect and that you are going to see those stars again. You spend all day lamenting about it. 

You crave for the starry night sky. And you are sure it would look like so :

So, the following night you go to the terrace to rejoice at the sight. But yet see that the sky is not starry at all as you had marveled. 

In fact, there is a stark difference between what you had in mind and what you observe.

You get increasingly concerned about it. You ask a few people around and you find out that the answer to this mysterious phenomenon is Light Pollution..

And you start to explore this new bizarre form of pollution.

What is Light Pollution?

Alteration of natural light levels in the outdoor environment owing to artificial light sources.

What does it do?

The impact of light pollution is to reduce our eye’s limiting magnitude. That means that we can see fewer and fewer stars.

The differences in the number of stars that can be seen due to varying levels of background light pollution.

Light pollution competes with starlight in the night sky for urban residents, interferes with astronomical observatories, and, like any other form of pollution, disrupts ecosystems and has adverse health effects.

Light pollution is a side effect of industrial civilization. Its sources include building exterior and interior lighting, advertising, commercial properties, offices, factories, streetlights, and illuminated sporting venues. 

How can I prevent it?

(Light Pollution and How to Reduce It)

The solution does not involve curtailing nightlife, hampering the nighttime economy or compromising safety. It just requires directing lights where they’re needed and eliminating waste.

Here what you can do prevent light pollution.

1) Only turn on outdoor lights when needed—or install motion sensors.

2) Point the lights downward and outfit them with “shields” to prevent light from traveling sideways. The goal is to shine them only where illumination is wanted—not in people’s eyes or on other people’s property (a case of “light trespass”).

3) Lower the wattage of your bulbs and put them on dimmers. Bright lights and dark shadows don’t improve safety, but reduce it.

4) Close curtains at night to keep indoor light in. If you live in a multi-story building, use black-out curtains to prevent bird crashes.

And, of course, please use energy-efficient lights to cut global warming emissions even more than you’ll be doing already.

Inspiration :

Here’s what the night sky looks now, with light pollution.

And here’s how it will look like without it.

This post is to educate all the followers of the blog about Light Pollution, and raise awareness about it.

“Stars can’t shine without Darkness”

and hence i urge you to do your part to curbing Light Pollution.

Have a good day :)

Scientists extend an atom’s lifetime with a mirror

Scientists from Chalmers University of Technology have been able to extend the lifetime of an artificial atom, allowing it to remain charged for up to ten times longer. They achieved this by placing the artificial atom in front of a short circuit, which acts as a mirror. The distance between the atom and the mirror affects how long the atom “lives,” which is the time from when an atom is charged to when it returns to its ground state.

Research team leader and Professor of Physics Per Delsing says, “We can vary the lifetime of the atom by changing the distance between the atom and the mirror. If we place the atom at a certain distance from the mirror the atom’s lifetime is extended by such a length that we are not even able to observe the atom.”
