Here is a set of science and tech-based photos, culled from various sources in the past week. Hopefully I should be able to return to doing regular tech posts soon.

High-resolution photo of Saturn's two-tone moon, Iapetus.

Undular bore are giant atmospheric waves, such as those captured in this photograph. Besides being pretty, they can amplify tornadoes if they strike them.

Light-emitting roofing tiles, so you can talk to the aliens when they come.

NASA has just released a set of new high-resolution images of Mars, like the one shown here.

World's smallest radio in comparison to other historical radios.

The actual face of King Tut, revealed this week.

Man-made tornado

This robotic SUV spent 6 hours navigating the streets of a deserted town without human intervention.

The pistol-cam is being adopted by NYC police to record what they were shooting at.

One drawback of kevlar is that the force of the bullet is still absorbed at the point of impact. Nanotube-based armour, scientists claim, should be able to spread the energy out, reducing injury.

The BOBBY scooter... a motorbike in a briefcase.

Edible printing material.

Recently-published research seems to show that aggression in adolescent boys may be linked to an amygdala (which is believed to be involved with fear response) that over-reacts to perceived threats in conjunction with lower activity in the prefrontal cortex (associated with reasoning and decision-making)

A church in Germany has beat out the Leaning Tower of Pisa as the most tilted building according to the Guinness Book of World Records.

Grand Prismatic Spring in the Yellowstone National Park, situated over a supervolcano, has been rising faster than ever due to an influx of magma. The cone is 70 km across, covering most of the park, and last erupted 70,000 years ago. Officials don't expect it to erupt any time soon.

Apparently the radio emissions of Saturn, when downshifted to the human range, are uncannily like the score for Forbidden Planet. Follow the link and listen for yourself.

50 years ago last Saturday (November 3), Laika become the first dog in space.  It is believed that she died a few hours after going into orbit as a result of overheating during launch.

The closest "solar twin" to our sun has been found in constellation Draco. it is known by the designation HIP 56948 and and is 200 light years from us and 1 billion years older. Three other stars, Scorpio 18, HIP 100963 and HIP 98614 were also in the running, but were deemed to have too much lithium to match our own sun.

An Italian musician claims to have found hidden musical notes in daVinci's Last Supper.

A set of Chinese-made toys were pulled from store shelves when it was discovered that they were coated in a chemical that, when ingested, metabolizes into gamma hydroxy butyrate... a date rape drug.

Here's another from joyeuse60, a wall-mounted cat post. Now I just need a wall strong to hold it.

Another one from joyeuse60, this time a corner frame. I think I have a shot that could work with this.

The Ford Nucleon, designed in 1958, was a nuclear-powered concept car. As you might guess, it never made it past the drawing board.

The head of what was believed to be the mythical blood-sucking chupacabra ("goat sucker"), was revealed to be a type of hairless coyote, thanks to DNA analysis.
