A theoretical physics institute must be a bit like a science-fiction starship, in that you actually have to take concepts like extradimensional wormholes and inflationary multiverses seriously. If that's the case, then give a "Star Trek" salute to the Perimeter Institute for Theoretical Physics' new captain: cosmologist Neil Turok.

Images from NASA's Mars Reconnaissance Orbiter are providing an advance peek at what the Phoenix Mars Lander will be running up against when it lands near the planet's north pole later this month: The spacecraft will be coming down in the middle of a spring thaw, and based on the pictures released this week, there just might be some Martian mini-tornadoes swirling through the scene.
Two of the twisters, known as dust devils, show up on an April 20 image of Phoenix's projected landing area, taken by MRO's Context Camera. The Martian whirlwinds are similar to the desert mini-twisters often seen on Earth - and have previously been caught on camera by the Mars Pathfinder lander as well as NASA's Spirit rover. You can watch a dust devil spin through Spirit's line of sight in this year-old video clip.

NBC News' Tim Russert isn't the only one selling Hillary Clinton short today: In the wake of the North Carolina and Indiana primaries, her shares on the Iowa Electronic Markets have fallen to the lowest point ever. The market lets online investors put real money down on the candidates’ prospects, as a science experiment on the "wisdom of crowds." The shares are worth $1 each if the investor's candidate wins the nomination, but they're worthless if the candidate loses.
Today, Clinton’s shares for the Democratic nomination were trading at less than 10 cents on the IEM - and the situation was pretty much the same at the InTrade prediction market.

The catastrophic cyclone that hit Myanmar hints at the shape of things to come in a warming world — but probably not for the reason you think. Chris Mooney, the author of "Storm World," argues that the tragedy says more about the sad state of infrastructure in the developing world than it does about the raw impact of climate change. However, shifts in climate will likely accentuate that global rich-vs.-poor split.

Cal Orey says her Brittany spaniels, Simon
and Seth, help her predict seismic events.

Tiny earthquakes have been swarming near Reno for weeks, and seismic experts are trying to gauge whether things are settling down or heading toward a bigger rumble. All this is making some of the region's residents jittery - including Cal Orey, who lives near Lake Tahoe and issues earthquake predictions based on such things as headaches, pet behavior and moon phases.
Orey made headlines when she called the current wave of shakers in advance - and now she thinks a stronger quake could hit by the end of this month. To be specific, she's predicting a 70 percent chance of a magnitude-5 to magnitude-6 quake in the Reno/Tahoe/Sierra region by the end of May.
"I'm not saying 100 percent," she told me today. "But it's likely."
Seismologists don't tend to put stock in such predictions, as I explained in a report about quake forecasting a couple of years ago. However, the practical effect of what the experts are saying is pretty much the same: Be prepared for a Bigger One.
