From Science Daily:

Science Daily (Jan. 20, 2010) — A new model for primate origins is presented in Zoologica Scripta, published by the Norwegian Academy of Science and Letters and The Royal Swedish Academy of Sciences. The paper argues that the distributions of the major primate groups are correlated with Mesozoic tectonic features and that their respective ranges are congruent with each evolving locally from a widespread ancestor on the supercontinent of Pangea about 185 million years ago.

Ability To Recognize Faces Is Inherited

From Live Science:

Some people never forget a face. For the rest of us, recognizing faces is not so easy. And those with prosopagnosia can't even recognize their close friends.

Now scientists say the ability to recognize faces is inherited and separate from general intelligence or IQ.

IQ is strongly heritable. And one longstanding general thought about IQ holds that if you're smart in one area, you'll be smart in others. But some skills seem distinct. A person can be brilliant with numbers but not good with linguistics, for example. This latter reality supports a modularity hypothesis, in which the mind is like a Swiss Army knife — a general-purpose tool with special-purpose devices, researchers explained.

Himalayan Melting: How A Climate Panel Got It Wrong

From Time Magazine:

Between the undying controversy that was "Climategate" and the near collapse of the Copenhagen summit on global warming, 2009 was not a great year for climate scientists or activists. Less than a month into the new year, 2010 isn't looking much better.

On Wednesday (the day after Republican Scott Brown, an opponent of cap and trade, seized a U.S. Senate seat in Massachusetts), a new scandal broke over climate science. Faced with criticism of a widely quoted piece of analysis from its 2007 climate assessment that warned that Himalayan glaciers could melt by 2035, the U.N. Intergovernmental Panel on Climate Change (IPCC) was forced to admit to relying on dubious scientific sources, apologized and retracted its earlier estimate. That estimate of the rate of Himalayan glacier loss because of warming, which appeared in the same assessment that earned the global body a share of the Nobel Peace Prize, was "poorly substantiated," the IPCC said.

From L.A. Times:

The first jumbo jet made its maiden commercial flight 40 years ago today. More than 1,400 of the planes with their signature hump have rolled off the Boeing assembly line.

It was the kind of plane that seemed to fit the swinging go-go days with martini-swigging travelers lingering around a bar.

First-class passengers dressed in their Sunday best made their way up a spiral staircase to get to the "flying penthouse," harking memories of private rail cars.

It seemed the epitome of plushness when it made its first commercial flight 40 years ago today. A Times reporter described the cabin as a "luxurious auditorium some genie had wafted aloft."

The Sound of Saturn's Rings



From Universe Today:

This wonderful video was posted by Jennifer Ouellette on Discovery News, and I just had to share it. The sounds are actual recordings picked up by the Cassini spacecraft. I have heard the eerie audio before, but never had previously seen it paired up with moving images from the mission. The radio emissions, called Saturn kilometric radiation, are generated along with Saturn's auroras, or northern and southern lights. Cassini's Radio and Plasma Wave Science (RPWS) instrument takes high-resolution measurements that allow scientists to convert the radio waves into audio recordings by shifting the frequencies down into the audio frequency range.

Environmental Cleanup Starts Amid Haiti Rubble



From Discovery News:

Experts have started assessing how to deal with the masses of rubble and hazardous waste left in the wake of the Haiti quake.


Just a week after Haiti's catastrophic magnitude 7.0 earthquake, getting aid to victims remains a top priority, but experts are also now starting to assess how to coordinate the sorting and disposing of building rubble.

So far, no large industrial spills have been found. The biggest environmental issue, according to the United Nations Environment Program, is dealing with all of the building waste generated by the earthquake, which destroyed at least 40-50 percent of the buildings in the capital, Port-au-Prince, and devastated other towns in the area.

The Global Shipping Network Is Finally Revealed


From Technology Review:

Despite carrying 90 percent of the planet's trade, nobody has mapped the network of links between the world's ports. Until now.

The International Maritime Organization based in London estimates that 90 percent of the world's trade is moved around the planet by sea. Given the fascination that complexity scientists have with rail, air and road networks, it seems strange that so little attention has been paid to the maritime network.
