Physics students at Brigham Young University have produced this tiny cupid from carbon nanotubes that are 10,000 times smaller than a human hair!
The project began by laying down microscopic iron "seeds" to form a Cupid pattern. When they applied a heated gas to the iron, the seeds sprouted into the desired shape. Each nanotube is 99% air and measures roughly 20 atoms across. Like love, it's a very fragile structure. Treat it with care! =D

When a meteoroid hits the atmosphere, it generates a bright streak of light caused by vaporizing solids and gases. This streak of light can actually be very valuable to physicists because spectral analysis of the light provides information about the composition of the meteoroid.

I thought Philippe Roux & Josh Lewin's points were spot on. Your comment added nicely to theirs & I appreciate your further investigation into this mystery. Not only is it interesting to see the source of this gif (BBC documentary) but also the fantastic footage of the night sky (without light pollution!). =) Thanks again!
As part of the first demonstration of laser communication with a satellite at the moon, scientists with NASA's Lunar Reconnaissance Orbiter (LRO) beamed an image of the Mona Lisa to the spacecraft from Earth.
The iconic image traveled nearly 386,243 km or 240,000 miles in digital form from the Next Generation Satellite Laser Ranging (NGSLR) Station at NASA's Goddard Space Flight Center in Greenbelt, MD, to the Lunar Orbiter Laser Altimeter (LOLA) instrument on the spacecraft. By transmitting the image piggyback on laser pulses that are routinely sent to track LOLA's position, the team achieved simultaneous laser communication and tracking.

I don't think that a straight line is the only possible path.
As I read somewhere.. if we distort space and time, and reshape it, anything that is inside space and time will be affected such as waves, for example.
Waves can be bent and can follow different paths as we change the geometric properties of the space they live in.
So what does this mean exactly?
Some silliness first... when I was a teen I wrote a story about scifi story about sailing ships with huge reflective solar sails traveling the cosmos on solar winds and reflecting light to each other and from above to settlements below when they were in a planetary orbit. That old idea got me thinking about a series of strategically placed lenses made of distorted space-time could forward quantum data anywhere ... optically lenses can magnify as well ;) and so although light may normally take a long time to travel perhaps we can bend space-time and use "lenses" to reach a location very quickly ... that said we can do that with our minds already... anyways....my imagination runneth over, back to terra firma and science ....
Well, this could easily be a hundred page post so, for instance, on a very basic level let's look at what we are learning about self-bending light here:
Go to http://scaleofuniverse.com/ for a fun, interactive, visual representation of everything around us using powers of 10! =) Included along the way are explanations of each item beginning at the smallest to the largest according to Cary & Michael Huang.
They start with the smallest or Quantum Foam (1 x 10^-35). According to the spacetime theory, quantum foam, which is also known as spacetime foam, is the foundation of the fabric of the universe. It is impossible to directly observe or measure this because it is so small.
Their end with the largest or Distance to the Hubble Deep Field (1.27 x 10^26). The Hubble Space Telescope took a picture of an empty spot in the night sky. Instead of nothingness, the image had almost 3000 objects in it - distant galaxies. It's unknown where these galaxies are now, but where they were 12.7 billion years ago is 12.7 billion light-years away from us.

Researchers Tilo Müller and Michael Spreitzenbarth at Erlangen University in Germany have shown that a trick known as a “cold boot attack” can read data from a smartphone running the latest version of Android, even when the phone is protected by a PIN and has its storage disk encrypted.
To access the cryptographic key stored in the phone's memory, they placed the phone in the freezer compartment for an hour, with the result that the memory content remained – almost literally – frozen. By cooling the device to below 10 degrees, the volatile memory can be made to retain data for a short period of time without power.
They exploit this to disconnect the battery for a moment, resulting in a reboot then use a key combination to invoke the bootloader, allowing them to flash and run their own recovery image, dubbed "FROST" (Forensic Recovery of Scrambled Telephones).

Today we have the opportunity to unite and dance together in solidarity and support for our sisters around the world who do not have the good fortune to be free, safe, or know what it feels like to love & be loved in return. Together we have the power to break the cycle of violence so that generations of girls and women will not have to experience it.
The One Billion Rising movement is:
+ A global revolution
+ A call to men and women to refuse to participate in the status quo until rape and rape culture ends
+ An act of solidarity, demonstrating to women the commonality of their struggles and their power in numbers
+ A refusal to accept violence against women and girls as the norm
+ A new time and a new way of being
This is an invitation to dance. Join us! =D

Coments are celestial bodies moving about the sun, usually in a highly eccentric orbit, consisting of a central mass surrounded by an envelope of dust and gas that may form a tail that streams away from the sun. They are cold bodies, and become visible because the gases in their comae and tails fluoresce in sunlight (somewhat akin to a fluorescent light) and because of sunlight reflected from the solids.
Below is an amazing image of Comet C/2012 F6 Lemmon taken by from New Zealand. Comet C/2012 F6 was discovered by A. R. Gibbs (Mount Lemmon Survey) on 23 March 2012, 20.7 mag. Olsen original G+ post has a great explanation of how he captured the Comet Lemmon image & equipment he used (http://goo.gl/sPXfi).
2013 starts to look great as the year for comets! =) Thanks to for his excellent comet posts and to the astrophotographers & sky watchers.

A moon dog, moondog, or mock moon, (scientific name paraselene, plural paraselenae, i.e. "beside the moon") is a relatively rare bright circular spot on a lunar halo caused by the refraction of moonlight by hexagonal-plate-shaped ice crystals in cirrus or cirrostratus clouds. As determined by the crystal geometry, paraselenae are seen at an angle of 22 degrees or more from the Moon. Compared to the bright lunar disk, paraselenae are faint and easier to spot when the Moon is low.
Moonlight illuminates a snowy scene in this night land and skyscape made on 17 January 2013 from Lower Miller Creek, Alaska, USA. Overexposed near the mountainous western horizon is the first quarter Moon itself, surrounded by an icy halo and flanked left and right by moondogs.

Hugging someone can help reduce stress, fear and anxiety, has a lowering effect on blood pressure, promotes wellbeing and improves memory performance. These positive effects are caused by the secretion of the peptide oxytocin – but only when we are hugged by someone you trust.
