Don’t forget to set your clocks ahead tonight! Daylight Saving Time begins tonight for most of the United States and Canada. The expansion of the period we use DST is due to the Energy Policy Act of 2005; although studies show the effect on energy consumption is negigible, if not counterproductive. DST will last until the first weekend in November, which is almost two-thirds of the year. European Summer Time begins the last Sunday in March and runs til the last Sunday in October. Nations in the southern hemisphere who observe the practice have been on DST for months, and will soon go back to standard time as their fall approaches. Wikipedia has more on Daylight Saving Time history and practices around the world. Link

Universe Today looks at the possibility of humans traveling to Mars. One of the major roadblocks to such a mission is arranging for a return flight. A one-way mission would eliminate a lot of research and expense, but is it ethical?

Even though explorers in the past traveled, for example, to the south or north pole, knowing they might never return, and thousands of immigrants moved to the US in the 18- and 1900's, knowing they would never see their homeland again, the human psyche has seemingly changed enough that a one-way ticket off the planet is not acceptable. According to psychologist Molly Dooley from Springfield, IL, it might take a major crisis on Earth for humans to seriously consider such a mission. “Usually it’s the disenfranchised that are willing to take those kinds of risks," she said. “When our present situation no longer works for us, we become more willing to take risks. The difference between the folks who are interested and those who aren’t is their attachment to their current situation."

The Becohanger by Wannabeco is a new clothes hanger made from environmentally-friendly carboard. It is completely biodegradable, and may replace wire hangers in Britain.

"Each year 100 million wire coat hangers are put into UK landfill where they take centuries to degrade - it is this we are trying to prevent," said Alexander Beattie, Head of marketing at Wannabeco.

"We have worked out a way to alleviate this problem as well as provide an innovative and ecologically friendly media space for our advertising clients".

Yes, the hangers will be paid for by advertisers, and distributed to dry cleaners. The ads will be printed with environmentally-friendly ink. Link -via Fark

The Greek gods Hermes and Aphrodite had a child named Hermaphroditus. You can pretty much gather where the story leads from that alone. The legend of Hermaphroditus doesn’t quite explain why some people are born intersexual, but it’s an interesting tale. Link

This 3-way chessboard was purchased in the Czech Republic. The pieces move in the same way as normal chess, but that becomes a little weird in the center of the board, where six “squares” ajoin. The first person to checkmate either of the other two wins. The biggest problem I see is finding two people who want to play with you! http://meignorant.com/3-way_chess -via the Presurfer

Salar de Uyuni is the world's largest salt flat, high in the Andes mountains in Bolivia. In the rainy season when it is covered with a thin sheet of water, it reflects the sky.

Due to its large size, smooth surface, high surface reflectivity when covered with shallow water, and minimal elevation deviation, Salar de Uyuni makes an ideal target for the testing and calibration of remote sensing instruments on orbiting satellites used to study the Earth.

The salt flat contains an estimated ten billion tons of salt, in a layer ten feet thick. See more pictures and videos at Fogonazos. Link -via Reddit

Residents of a French village are under orders not to die, because the cemetery is full!

It added: "Offenders will be severely punished."

The manner of punishment was not specified. The order came after an administrative court ruled against the aquisition of private land to annex the existing parish cemetery. Link

Movie monsters are getting bigger and tougher over time, and it may take new technologies to defeat them. Danger Room takes a look at the new and improved monsters, and the weapons the military should use to defend humanity.

It's difficult to make accurate assumptions about 500 foot-tall fictional monsters whose very existence violates the laws of physics. But it's liable to have skin, scales or other outer with protective blubber or equivalent covering several feet thick. This will absorb anything except apart from an armor-piercing round. Flesh, like water, can stop virtually any projectile within a few feet – that's why you need something very exotic like a supercavitating round if you want to go through a lot of it. Those supercavitating Russian APS underwater assault rifles might be handy here... but you'd need a lot of rounds to have any effect.
