H-index Rank for Countries: for Science Publications

The SCImago Journal and Country Rank provides journal and country scientific indicators. As stated in previous posts, these types of rankings have limitations but they are also interesting. The table shows the top 6 countries by h-index and then some others I chose to list (the top 6 repeat from my post in 2008 – Country H-index Rank for Science Publications). The h-index provides a numeric indication of scientific production and significance (by looking at the citations given papers by other papers). Read more about the h-index (Hirsh index).

Lobopodians from China a Few Million Years Ago

Cactus Walking On 20 Legs Found In China

There was a wild period — roughly 520 million years ago — when life, for no obvious reason, burst into a crazy display of weird new fantastic forms — producing creatures in shapes never seen before or since. Consider this animal, the newest fossil discovery from Jianni Liu in China. She calls it “the walking cactus.”

This is not a plant, not a sculpture. It was a live animal, with no eyes, what may or may not be a head, mostly a gaggle of limbs, armor-plated, covered in thorns, attached to a stomach.

What is it? Taxonomically, Jianni Liu thinks it’s a lobopodian, a group of animals described as “worms with legs.” Lobopodians are about the craziest looking critters that ever lived. A whole zoo of them appear in the rocks around Chengjiang, China.

All we know, says Richard Fortey in his classic history Life, is that a long time ago, the first of these strange animals popped into view and for a short while “there was a chain reaction, unstoppable once it started, a bacchanalia of zoological inventiveness, which has never been matched again.”

Every living thing on earth today is what’s left over from that amazing burst of forms. It’s true we now live on land and in the air, not just in the sea. We have grasses and flowers and beetles in more varieties than you can imagine, and yet, in some deep architectural way, the developmental paths were set way back then, 500 million years ago. The Walking Cactus is just another souvenir of that crazy moment.

Very cool. Actual science is so full of such interesting things. The Cambrian explosion of life, about 540-490 million years ago, marked the beginning of complex life on earth. Before Cambrian, the sea floor was covered by microbial mats. By the end of the period, burrowing animals had destroyed the mats through bioturbation, and gradually turned the seabeds into what they are today. Generally it is accepted that there were no land plants at this time, although it is likely that a microbial “scum” comprising fungi, algae, and possibly lichens covered the land.

Complex organisms gradually became more common in the millions of years immediately preceding the Cambrian, but it was not until this period that mineralized (readily fossilized) organisms became common. Before about 580 million years ago, most organisms were simple, composed of individual cells occasionally organized into colonies. Over the following 70 or 80 million years the rate of evolution accelerated by an order of magnitude (as defined in terms of the extinction and origination rate of species) and the diversity of life began to resemble today’s.

USA Losing Scientists and Engineers Educated in the USA

The USA continues to lose ground, in retaining the relative science and engineering strength it has retained for the last 50 plus years. As I have said before this trend is nearly inevitable – the challenge for the USA is to reduce the speed of their decline in relative position.

A new open access report, Losing the World’s Best and Brightest, explores the minds of current foreign science and engineering students that are studying in the USA. This is another in the list of reports on similar topics by Vivek Wadhwa and Richard Freeman. And again they point out the long term economic losses the USA is setting up by failing to retain the talent trained at our universities. It is a problem for the USA and a great benefit for countries like India and China.

“Foreign students receive nearly 60% of all engineering doctorates and more than half of all mathematics, computer sciences, physics and economics doctorates awarded in the United States. These foreign nationals end up making jobs, not taking jobs,” said Wadhwa. “They bring insights into growing global markets and fresh ideas. Research has shown that they even end up boosting innovation by U.S. inventors. Losing them is an economic tragedy.”

According to the study’s findings, very few foreign students would like to stay in the United States permanently—only 6% of Indian, 10 percent of Chinese and 15% of Europeans. And fewer foreign students than the historical norm expressed interest in staying in the United States after they graduate. Only 58% of Indian, 54% of Chinese and 40% of European students wish to stay for several years after graduation. Previous National Science Foundation research has shown 68% of foreigners who received science and engineering doctorates stayed for extended periods of time, including 73% of those who studied computer science. The five-year minimum stay rate was 92% for Chinese students and 85% for Indian students.

The vast majority of foreign student and 85% of Indians and Chinese and 72% of Europeans are concerned about obtaining work visas. 74% of Indians, 76% of Chinese, and 58% of Europeans are also worried about obtaining jobs in their fields. Students appear to be less concerned about getting permanent-resident visas than they are about short-term jobs. Only 38% of Indian students, 55% of Chinese, and 53% of Europeans expressed concerns about obtaining permanent residency in the USA.

On the tonight show yesterday, President Obama said

we need young people, instead of — a smart kid coming out of school, instead of wanting to be an investment banker, we need them to decide they want to be an engineer, they want to be a scientist, they want to be a doctor or a teacher.

And if we’re rewarding those kinds of things that actually contribute to making things and making people’s lives better, that’s going to put our economy on solid footing. We won’t have this kind of bubble-and-bust economy that we’ve gotten so caught up in for the last several years.

Eric Schmidt, Google CEO, recently expressed his frustration with the policies discouraging science and engineering graduates staying in the USA after they complete their education.

That is a brilliant [actually not brilliant at all] strategy take the best people hire them in American universities and then kick them out” It happens. “Its shocking.” It happens. “I know we are fighting against it.” “We America remain, by far the place of choice for education, particularly higher education.”

Making Embryonic Stem Cells

photo of Junying Yuphoto of Junying Yu, an assistant scientist with the University of Wisconsin-Madison by Bryce Richter, 2007.

Holy Grail of stem cell research within reach by Mark Johnson

It was time to test the 14 genes she had selected as the best candidates to reprogram a cell.

Using viruses to deliver the genes, she inserted all 14 at once into human cells. On the morning of July 1, 2006, Yu arrived at the lab and examined the culture dishes. Her eyes focused on a few colonies, each resembling a crowded city viewed from space. They looked like embryonic stem cells.

Cells must pass certain tests. They must multiply for weeks while remaining in their delicate, primitive state. When they are allowed to develop, they must turn into all the other cell types.

Bad things happen. Cells develop too soon. Cells die. There is no “aha!” moment, Thomson has said, only stress. He looked at the colonies and suppressed any excitement. He told Yu, essentially: OK, well get back to me in a couple of weeks.

In the fall of 2006, Yu was preparing to whittle down her list of genes when she fell ill. The pain in her gut was awful. She struggled to eat. Her doctor thought it was a stomach flu. Instead, in late October, Yu’s appendix burst. She was laid up for a month. When she returned to the lab, the problem with the culture medium struck again.

Not until January 2007 was she able to begin narrowing the list of genes. She spent several months testing subsets of them, finally arriving at four. Two, Oct4 and Sox2, were “Yamanaka factors,” the name given to the genes the Japanese scientist had used to reprogram mouse cells. Two, Nanog and Lin28, were not.

Using a virus to deliver the four genes, she reprogrammed a line of fetal cells, then repeated the experiments with more mature cells. Although the process was inefficient, succeeding with only a small fraction of cells, it did work.

Dr. Junying Yu, an American trained scientist who entered the US as a foreign student from China. Which is somewhat ironic given the movement of USA based stem cell researches to China. Great article showing the process of scientific inquiry.

Best Research University Rankings – 2008

The annual ranking of research Universities are available from Shanghai’s Jiao Tong University. The methodology values publications and faculty awards which provides a better ranking of research (rather than teaching). Results from the 2008 rankings of Top 500 Universities worldwide, country representation of the top schools:

location Top 100 % of World
Population
% of World GDP % of top 500
USA 54     4.6%   27.2%  31.6%
United Kingdom 11  0.9  4.9 8.3
Germany   6  1.3  6.0 8.0
Japan   4  2.0  9.0 6.2
Canada   4  0.5  2.6 4.2
Sweden   4  0.1  0.8 2.2
France   3  0.8  4.6 4.6
Switzerland   3  0.1  0.8 1.6
Australia   3  0.3  1.6 3.0
Netherlands   2  0.2  1.4 2.4
Denmark   2  0.1  0.6 0.8
Finland   1  0.1  0.4 1.2
Norway   1  0.1  0.7 0.8
Israel   1  0.1  0.3 1.2
Russia   1  2.2  2.0 0.4
China  20.5  6.6 6.0
India  17.0  1.9 0.4

There is little change in most of the data from last year, which I think is a good sign, it wouldn’t make much sense to have radical shifts over a year in these rankings. Japan lost 2 schools in the top 100, France lost 1. Denmark (Aarhus University) and Australia (University of Sydney) gained 1. Last year there was a tie so there were 101 schools in the top 100.

The most dramatic data I noticed is China’s number of top 500 schools went from 14 to 30, which made me a bit skeptical of what caused that quick change. Looking more closely last year they reported the China top 500 totals as (China 14, China-Taiwan 6 and China-Hong Kong 5). That still gives them an impressive gain of 5 schools.

Singapore has 1 in the 102-151 range. Taiwan has 1 ranked in the 152-200 range, as do Mexico, Korea and Brazil. China has 9 in the 201-302 range (including 3 in Hong Kong). India has 2 in the 303-401 range.

University of Wisconsin – Madison is 17th again :-) My father taught there while I grew up.

How Humans Got So Smart

Cooking and Cognition: How Humans Got So Smart

For a long time, we were pretty dumb. Humans did little but make “the same very boring stone tools for almost 2 million years,” he said. Then, only about 150,000 years ago, a different type of spurt happened — our big brains suddenly got smart. We started innovating. We tried different materials, such as bone, and invented many new tools, including needles for beadwork. Responding to, presumably, our first abstract thoughts, we started creating art and maybe even religion.

To understand what caused the cognitive spurt, Khaitovich and colleagues examined chemical brain processes known to have changed in the past 200,000 years. Comparing apes and humans, they found the most robust differences were for processes involved in energy metabolism.

The finding suggests that increased access to calories spurred our cognitive advances, said Khaitovich, carefully adding that definitive claims of causation are premature.

Nice example of scientific discovery in action. The direct link from cooking to brain development is far from proven but it is interesting. I also like “the same very boring stone tools for almost 2 million years” – maybe that is because I am too cynical (but while evolution is amazing – sometimes it is amazing how slow progress is).

Why did China’s Scientific Innovation Stop?

Why did China’s scientific innovation, once so advanced, suddenly collapse

By the time Joseph Needham died in 1995, he had published 17 volumes of his Science and Civilisation in China series, including several that he wrote entirely on his own.

The Chinese began printing 600 years before Johannes Gutenberg introduced the technique in Germany. They built the first chain drive 700 years before the Europeans. And they made use of a magnetic compass at least a century before the first reference to it appeared elsewhere. So why, in the middle of the 15th century, did this advanced civilisation suddenly cease its spectacular progress?

Needham never fully worked out why China’s inventiveness dried up. Other academics have made their own suggestions: the stultifying pursuit of bureaucratic rank in the Middle Kingdom and the absence of a mercantile class to foster competition and self-improvement; the sheer size of China compared with the smaller states of Europe whose fierce rivalries fostered technological competition; its totalitarianism.

International Engineering Education Data: USA, China, India

Several years ago we posted about the report on the USA Under-counting Engineering Graduates. The authors, and two others, have written a new report that provides some useful additions – Getting the Numbers Right: International Engineering Education in the United States, China, and India

Since the late 1990s, the United States had a modest increase in bachelor’s degree output, from just over 103,000 in 1998–99 to more than 137,000 in 2003–04 before declining slightly to about 129,000 in 2005–06, a growth of nearly 25 percent since 1998–99. India’s expansion at the bachelor’s level was more rapid, with four-year degree holders in engineering, CS, and IT more than tripling in the last seven years, from just over 68,000 in 1998–99 to nearly 220,000 in 2005–06. The fastest growth in bachelor’s degrees, however, appears to be occurring in China. According to the Chinese MoE, the number of bachelor’s degrees awarded has more than doubled in the last four years, from 252,000 in 2001–02 to 575,000 in 2005–06.

While engineering, CS, and IT degree production in the United States has been stable or increasing at all degree levels over the past ten years, a sizable percentage of these degrees are indeed being
awarded to foreign nationals. Statistics collected by the ASEE on bachelor’s, master’s and Ph.D. degrees in engineering indicate that during the 2005–06 academic year, 7.2 percent, 39.8 percent and 61.7 percent of these degrees, respectively, were awarded to foreign nationals (Figure 4). As these figures indicate, the percentage of foreign nationals is significantly higher at the graduate level, especially for Ph.D. degrees.
