Older People Hold Stronger Belief in God
Across the world, people have varying levels of belief (and disbelief) in God, with some nations being more devout than others. But new research reveals one constant across parts of the globe: As people age, their belief in God seems to increase. -

The shape of things, illuminated: Metamaterials, surface topology and light-matter interactions
(Phys.org) -- Finding new connections between different disciplines leads to new – and sometimes useful – ideas. That’s exactly what happened when scientists in the Department of Physics, Queens College, City University of New York (CUNY), in collaboration with City College of CUNY, Purdue University and University of Alberta, leveraged mathematical topology to create an artificially nanostructured anisotropic (exhibiting properties with different values when measured along axes in different directions) metamaterial that can be switched from a non-conductive dielectric state to a medium that behaves like metal in one direction and like a dielectric another. The metamaterial’s optical properties was mapped onto a topological transformation of an ellipsoidal surface into an hyperboloid – and transitioning from one to the other dramatically increases the photon density, resulting in dramatic increase in the light intensity inside the material. The researchers state that by allowing topologically-based manipulation of light-matter interactions, these types of metamaterials could lead to a wide range of photonic applications in solar cells, light emitting diodes, displays, and quantum computing and communications. -
16:50When your head hits the pillow, for many it's lights out for the conscious part of you. But the cells firing in your brain are very much awake, sparking enough energy to produce the sometimes vivid and sometimes downright haunted dreams that take place during the rapid-eye-movement stage of your sleep.

13:24Hackers tried to get the best of Hotmail by figuring out how to reset Hotmail user passwords for e-mail accounts this month. Locking hotmail users out of their own accounts when trying to key in their passwords was something like a bad-dream scenario, trying to open your front door only to find your key does not work and thieves are inside. This could have turned into a big-time nightmare if Microsoft, after being notified of the weakness, had not rushed out a patch for its troubled password reset system. The Redmond company reportedly closed the loophole, so that hackers trying to manipulate data would now get an error message.

Who could have ever thought that a perpetually depressed nihilistic French cat could be so amusing?
This week's Caturday morning video smile is a little bit different from the usual fare. Instead of featuring amusing and peculiar animal (or plant) behaviour, I am sharing an artsy film that will either give you a smile or make you more depressed than you already are. I'm betting on a smile.
This black-and-white video features a black-and-white longhaired cat named Henri, who is a perpetually depressed nihilist. The film also includes poorly pronounced French narration accompanied by amusing English subtitles and a soundtrack.
Music: "Nothing has Changed" performed by Vi Hart.
Henri is on facebook and twitter @HenriLeChatNoir

NOTE: the silly cat/pet/animal videos shared here on Saturday (Caturday) mornings are intended to amuse. This feature is designed to help hard-working and stressed-out people shed their professional façade so they can be better friends, companions, parents, family members and drinking pals to those in their personal lives. Any relationship between these videos and science or any scientific principle is sweet when I manage to present a solid connection to you, but is random, usually coincidental and (mostly) unintended.

09:23(Phys.org) -- The NASA/ESA Hubble Space Telescope has been at the cutting edge of research into what happens to stars like our sun at the ends of their lives. One stage that stars pass through as they run out of nuclear fuel is called the preplanetary or protoplanetary nebula stage. This Hubble image of the Egg Nebula shows one of the best views to date of this brief but dramatic phase in a star’s life.
