China challenges dominance of USA, Europe and Japan

China challenges dominance of USA, Europe and Japan in scientific research according to UNESCO Science Report 2005

The report says that “the most remarkable trend is to be found in Asia, where gross expenditure on R&D has grown from a world share of 27.9% in 1997 to 31.5% in 2002”.

This hardly seems impressive compared to the growth of Google say. However the amounts of money for global R&D are huge and so changes as less dramatic than other areas. Still this is significant and seems likely to continue to move in this direction.

The Brine Lake Beneath the Sea

The Brine Lake by Harry Roberts:

As we took the sub into the brine lake, the pressure wave from the sub’s movement across the lake created waves on the interface between the brine and the overlying normal-density sea water.

We watched these waves break on the “beach” like storm waves approaching and breaking on a sandy coastline.

NOAA researchers include a video from the adventure. Also read more about the Expedition to the Deep Slope, in the Gulf of Mexico.

Toyota Announces Overview of “Toyota Partner Robot”

Toyota wants its partner robots to have human characteristics, such as being agile, warm and kind and also intelligent enough to skillfully operate a variety of devices in the areas of personal assistance, care for the elderly, manufacturing, and mobility. Furthermore, since each area requires a special set of skills, Toyota is promoting the development of three different types of partner robots (walking, rolling, and mountable), each with its own areas of expertise.

Read posts about the Toyota Productions System (TPS) on the Curious Cat Management Improvement Blog.

Others are making progress on human like robots including Sony and Honda. See Sony QRIO Robots in action in this flash video below:

Psychology Experiment

Not Your Average Summer Camp by Marisa Brook

They would be pitted against each other in a lengthy tournament of sports and other challenges; the winner would be awarded a medal and a pocketknife. The psychologists’ aim was to prompt each team to see the other as an ‘enemy’ of sorts, and test the second part of the hypothesis.

Overall, the experiment was seen as a success. Not only had both aspects of Sherif’s hypothesis been verified, but several further conclusions had been reached.

Scientists and Students

Scientists ‘too busy’ for pupils BBC News:

The pressure to publish research means many scientists do not have time to go into schools to encourage pupils to take up sciences, a study suggests.

Obviously research is important. But, as the article points out, it is also important for primary school teachers and students to interact with practicing scientists. The benefits of those interactions are most likely going to pay dividends over the long term.

Ants on Stilts for Science

When Ants Go Marching, They Count Their Steps by Bjorn Carey

One is that they do it like honeybees and remember visual cues, but experiments revealed ants can navigate in the dark and even blindfolded. Another disproved hypothesis was that because ants scurry at a steady pace, they could time how long it took them to get to and fro. Other studies have shown that once ants find a good source of food, they teach other ants how to find it.

The ant “pedometer” technique was first proposed in 1904, but it remained untested until now.

Scientists trained desert ants, Cataglyphis fortis, to walk along a straight path from their nest entrance to a feeder 30 feet away. If the nest or feeder was moved, the ants would break from their straight path after reaching the anticipated spot and search for their goal.

A simple example of the scientific process (another one posted yesterday about birds and global warming).

Birds Fly Early

Spring Is Early, and So Are the Birds, NPR webcast

This is short real life example of the scientific method. Spring is coming earlier to Europe, thanks to global warming. Scientists figured migrating birds in southern Europe would be able to adjust to the change and leave early (because the early warming would also be obvious where they wintered). But the scientists expected that birds from Africa would not be able to tell that they should leave early.

However, they studied what actual took place and found that the migrating birds from Africa were actually arriving early while those in southern Europe were not. So now they are revising their theories and will do more study to try and determine what is happening and why (for example, how are the birds in Africa deciding to leave early?).

Large-Scale, Cheap Solar Electricity

Large-Scale, Cheap Solar Electricity by Kevin Bullis

This week, Nanosolar, a startup in Palo Alto, CA, announced plans to build a production facility with the capacity to make enough solar cells annually to generate 430 megawatts. This output would represent a substantial portion of the worldwide production of solar energy.

According to Nanosolar’s CEO Martin Roscheisen, the company will be able to produce solar cells much less expensively than is done with existing photovoltaics because its new method allows for the mass-production of the devices. In fact, maintains Roscheisen, the company’s technology will eventually make solar power cost-competitive with electricity on the power grid.

Nanosolar also announced this week more than $100 million in funding from various sources, including venture firms and government grants. The company was founded in 2001 and first received seed money in 2003 from Google’s founders Larry Page and Sergey Brin.

Open-Source Biotech

Open-Source Biotech:

Mr. Jefferson, the man credited with inventing one of the main tools used in plant genetic engineering, started his campaign in 1987 by doing what the big companies that dominate agricultural biotech rarely do: He shared his discovery of beta-glucuronidase gene (GUS), an indicator that tells where a gene is, how much it expresses, and when it acts.

GUS is widely credited for enabling many breakthroughs in plant biotech, including the development of one of Monsanto’s first and most profitable agricultural products, Roundup Ready soybeans. Mr. Jefferson first provided GUS and all the know-how to use it for free to hundreds of labs around the world.

When he secured his patents, he charged only what people could afford: Monsanto, he says, paid a substantial amount; academics and companies in the developing world, including those who wanted to use his work for commercial purposes, received it free of charge.
