Ancient Greek ships shipped more than just wine

5:28 pm

New data has shown that ancient Greek merchant ships transported a wide assortment of goods, not just wine.

What is interesting about this story is how it punctures a hole in an assumption too many archeologists have been making about the amphorae, the standard shipping container of the ancient Mediterranean:

Amphorae have been found in their thousands in wrecks all over the Mediterranean Sea. Some of them contain residues of food, such as olive pits and fish bones, but the vast majority of them are discovered empty and unmarked. Foley says historians tend to assume that these containers were used mainly to transport wine — in a survey of 27 peer-reviewed studies describing 5,860 amphorae, he found that 95% of the jars were described as having carried the beverage.

The new research found evidence for many things besides wine, illustrating again the dangers of assuming anything in science.

An archeology discovery in Africa suggests that Stone Age humans had an understanding of basic chemistry

9:15 pm

An archeology discovery in Africa suggests that Stone Age humans had an understanding of some basic but complicated chemistry.

Archaeologists have found evidence that, as long ago as 100,000 years, people used a specific recipe to create a mixture based on the iron-rich ochre pigment. The findings, published in the journal Science, “push back by 20,000 or 30,000 years” the evidence for when Homo sapiens evolved complex cognition, says Christopher Henshilwood of the universities of Bergen in Norway and Witwatersrand in Johannesburg, South Africa, who led the work. “This isn’t just a chance mixture, it is early chemistry. It suggests conceptual and probably cognitive abilities which are the equivalent of modern humans,” he says.

Space News suggests Congress use the billions for NASA’s heavy-lift rocket to fund JWST

3:51 pm

In an editorial yesterday Space News suggested that Congress use the billions it is allocating for NASA’s heavy-lift rocket to fund the James Webb Space Telescope instead.

This is not surprising. Webb already has a strong constiuency (astronomers, the public) while the Space Launch System has little support outside of Congress and the specific aerospace contractors who want the work. With tight budgets as far as the eye can see into the future, and the likelihood that Congress is going to become more fiscal conservative after the next election, it would not shock me in the slightest if SLS gets eliminated and the money is given to Webb. And if the SpaceX and Orbital Sciences cargo missions to ISS go well then cutting SLS would almost be a certainty, as this success would demonstrate that these private companies should be able to replace SLS for a tenth of the cost.

And I also think this would be a much wiser use of the taxpayers money.

A UN report says that nearly one billion people are hungry because of biofuels such as ethanol from corn

11:51 pm

A UN report this week says that nearly one billion people are hungry, partly because of biofuels such as ethanol from corn.

The findings are echoed in a report published today by the International Food Policy Research Institute (IFPRI), based in Washington DC. Maximo Torero, one of the report’s authors, says policymakers must “curtail biofuels subsidies” and “discourage the use of food crops in biofuel production” to limit food price volatility.

The space police of Baikonur

9:29 am

The space police of Baikonur.

I find this quote interesting:

When the status of the city was designated [after the fall of the Soviet Union], the leased Baikonur was monitored by two Interior Ministries, two prosecutors’ offices and two state security organs. But social problems have not disappeared. Engineers and astronauts are not the only ones who live in the city. Baikonur hosts a great deal of people who have local residence papers, including the indigenous Kazakhs. They cannot work on Baikonur objects because mostly Russians are hired to work there. If the Kazakhs are lucky enough to be hired, they are paid far less than the Russians.

In June of this year mass uprisings occurred in Baikonur. A crowd of youths pelted a police patrol car with stones and bottles.

The strange rubbing boulders of Chile

8:55 am

The strange rubbing boulders of Chile.

Then, on another trip to the Atacama, Quade was standing on one of these boulders, pondering their histories when a 5.3 magnitude earthquake struck. The whole landscape started moving and the sound of the grinding of rocks was loud and clear.

“It was this tremendous sound, like the chattering of thousands of little hammers,” Quade said. He’d probably have made a lot more observations about the minute-long event, except he was a bit preoccupied by the boulder he was standing on, which he had to ride like a surfboard. “The one I was on rolled like a top and bounced off another boulder. I was afraid I would fall off and get crushed.”

The abstract is here.

Rough Terrain

10:21 pm

The Dawn scientists have released another spectacular image of the south polar mountain on Vesta whose relative size is three times that of Mount Everest. More information about the image can be found here. From the caption:

The peak of Vesta’s south pole mountain, seen in the center of the image, rises about 13 miles (22 kilometers) above the average height of the surrounding terrain. Another impressive structure is a large scarp, a cliff with a steep slope, on the right side of this image. The scarp bounds part of the south polar depression, and the Dawn team’s scientists believe features around its base are probably the result of landslides.

Mountain on Vesta

It appears the light gravity on Vesta allows for the formation of extreme topology.

I am going to the west

2:20 pm

I was born and raised in Brooklyn, New York, and thus am undeniably what people call a city boy. Though in my youth my family spent summers in the country near Monticello in upstate New York, I never saw a real mountain. To me, a mountain was the typical rounded wooded hills of the Catskills and Adirondack Mountains.

The first time I traveled west of the Mississippi was when I was 33 years old, in 1986. I and five other caving friends went to New Mexico to attend that year’s annual caving convention. (We spent all of three hours at this week long convention. Instead of sitting in a college classroom listening to cavers talk about caving, we went caving in the Guadalupe Mountains, which to my mind was far more fun.)

When we first arrived in El Paso, we rented a car and started the three hour drive east towards Carlsbad Caverns where we planned to camp and cave for the first few days. At one point during the drive we stopped, just to look at the view. For a born Easterner who was used to hiking in forests where it might take you hours to reach a point where the trees thinned out enough to give you a lookout or vista, the west’s openness was breathtaking. Wherever you looked you could see for fifty to a hundred miles.

As I stood by the side of the road, I noticed something else, but could not put my finger on it at first. Something that was not obvious was different.
