The webcast shows a train transferring passengers without stopping. Essentially passenger modules are picked up and dropped off at each station. Looks pretty cool and would seem to require somewhat complex engineering - which can be a problem as complexity allows for more things to go wrong. Still it looks pretty cool. The sound is not in English but you can see what the idea is.

Pelf Nyok has posted drawing of turtle camps students that she taught in Malaysia. On the image shown on the left:
Pelf is on her way to the USA for turtle conservation training on the Asian Scholarship Program for in-situ Chelonian Conservation:
And the remaining 3 months would be spent at the Wetlands Institute at Stone Harbor, New Jersey. The training will be conducted at the Wetlands Institute, together with other local participants.
The trait in amphibians is likely an adaptation to life between water and land and their ability to respire through the skin. The researchers suggest lunglessness in B. kalimantanensis may be an adaptation to the higher oxygen content in fast-flowing, cold water.
…
Wake added that for most amphibians, the majority of gas exchange happens through the skin. A low but significant amount of respiration occurs via simple, sac-like lungs. Most species, he noted, have mating calls that require lungs. So biologists are unsure why a few species have entirely gotten rid of the organs, Wake said.

Inside Honda’s brain by Alex Taylor III
The wellspring of Honda’s creative juices is Honda R&D, a wholly owned subsidiary of Honda Motor. Based in Saitama, west of Tokyo, R&D engineers create every product that Honda makes - from lawn mowers to motorcycles and automobiles - and pursue projects like Asimo and Hondajet on the side. Defiantly individualistic, R&D insists on devising its own solutions and shuns outside alliances. On paper it reports to Honda Motor, but it is powerful enough to have produced every CEO since the company was founded in 1948.
…
The engineer in Fukui [Honda's president and CEO] cannot help but be intrigued by what his former colleagues are up to, and his office is only a few steps away from Kato’s. But even with the CEO just down the hall, says Kato, “We want to look down the road. We do not want to be influenced by the business.”
…
Honda allows its engineers wide latitude in interpreting its corporate mission. “We’ve been known to study the movement of cockroaches and bumblebees to better understand mobility,” says Frank Paluch, a vice president of automotive design. Honda R&D gets about 5% of Honda’s annual revenues. Most of the money goes to vehicle development, not cockroach studies
…
mistakes like the Insight are also the exception. R&D has provided Honda with a long list of engineering firsts that consumers liked, including the motorcycle airbag, the low-polluting four-stroke marine engine, and ultralow-emission cars.

Google, Gates, Indian Diaspora Bet on Children by Andy Mukherjee
Born into a poor, illiterate family in the western Indian state of Gujarat, Patel was lucky to break free of the poverty trap. Several people from his community had prospered in East Africa. They supported his studies.
…
at 30 U.S. cents per child per year, the basic math, reading and writing skills required to help young learners retain their interest in education and keep them from dropping out of school are ridiculously cheap. It’s also critical enough to have caught the attention not just of wealthy Indian communities overseas but also of the Menlo Park, California-based William and Flora Hewlett Foundation and the Bill & Melinda Gates Foundation.
Together, the two charities offered to help 10 million students for three years by pledging $9 million last year to Read India, an initiative of Pratham, a Mumbai-based not-for- profit organization for which Patel is a fund-raiser. Google.org, the philanthropic arm of Google Inc., chipped in last month with a $2 million grant to help fund Pratham’s annual survey of the qualitative aspects of primary education in India.

Millions of users around the globe could not access YouTube for a couple hours yesterday. Why?
Well to understand, we need to start with how you normally connect to a web site. You click on a link to youtube.com. Your ISP looks up the internet address for youtube.com by looking at internet routing tables. Each domain has a name server that provides the IP address for where it should be found (for example, an IP address that shows youtube.com is 208.65.153.238).
Well what happened in this case is Pakistan decided to prevent anyone in Pakistan from accessing YouTube because the government didn’t like some video. The way Pakistan decided to accomplish this was to update their routing table to just direct all traffic that was meant to go to YouTube to a phony address which would then return nothing.
Why did many outside of Pakistan lose access to YouTube? Well their version of the routing table leaked out of Pakistan through PCCW (large internet provider), Then other internet providers adopted the incorrect information, until many around the globe were being directed to the wrong place.
You might find it amazing the routing system could allow such a thing to happen - it doesn’t seem very secure. You are right, that it doesn’t seem very sensible. When the internet was created some protocols were established that made sense then but don’t necessarily make sense for what the internet has become.
The problem was fixed when Google’s YouTube engineers contacted PCCW to inform them of the problem and have them correct it. I think if it was my site instead, I would have had difficulty figure out what was going on 
Once PCCW corrected their routing tables the fixed flowed through the system and everyone was able to see the great stuff like Marissa Mayer discussing Innovation at Google.
I would imagine Internet2 (well on its way to a computer near you) and IPv6 will take not be so venerable to such a mistake.

China’s Sci-Tech Savvy Leadership by Jocelyn Ford
Ancient China is famous for its early scientific advances, some of which predated western developments by centuries. Its inventions include paper, printing, gunpowder and the compass.
…
Leadership does matter, but so does the system. It seems to me it should take a lot longer for China to build a sci-tech friendly system than for the U.S. to bring in sci-tech friendly leadership. That’s where you come in Ira & co.
If I may make one final comment: in my ideal world, borders shouldn’t matter. Victory by the best system, with the best leaders, will hopefully be a victory for all earthlings.

CHINA’S POLITBURO (2007): Decline of the engineer. Last fall China introduced a new top lineup that included two law graduates, as well as an economist, and graduates in history, journalism, management and business administration.
I agree that the increase in science and engineering investment around the globe is a positive development. But the USA faces loses that it has enjoyed due to past technology leadership.
China benefits greatly from such scientific knowledge at the highest level of government. The top 9 leaders in China are know as the “Politburo Standing Committee,” the new additions in 2007 were:
Xi Jinping, 54, studied chemical engineering at the Qinghua University and later earned a doctorate in law.
Li Keqiang, 52, obtained MA and doctorate of Economics after attending the on-the-job postgraduate program on Economics at the School of Economics of Peking University.
He Guoqiang, 63, B.S. Beijing Institute of Chemical Engineering.
Zhou Yongkang, 64 “Graduated from the Exploration Department, Beijing Petroleum Institute, majoring in geophysical exploration. With a university education. Senior engineer with a rank equivalent to professor. ” Funny, I don’t remember any U.S. politician exalting their experience as “equivalent to a professor.”
They joined the nine-member echelon with the five remaining members of the previous standing committee, namely Hu Jintao, Wu Bangguo, Wen Jiabao, Jia Qinglin and Li Changchun.

Different Engineering Education Expectations
On the contrary, however, engineering professors gave high marks of 97 out of 100 on their knowledge, and answered positively regarding their teaching skills, which revealed the different views colleges and companies have.
The conflict between what is being taught and what is needed in business is the subject of continuing debate globally.

The Webometrics Ranking of World Universities provides another estimate of the top universities. The methodology is far ideal however I still find it interesting. The various attempts to rank schools can provide a general idea of impact of various institutions (though the measures are fairly crude). Still a sensible picture (especially at the country level) can emerge. And the various rankings should be a able to track shifts in the most influential institutions and relative country strength over time. How quickly those rankings track changes will vary depending on the measures used. I would imagine most will lag the “real” changes as it is easy to imagine many measures that would lag. Still, as I have said before, I expect the USA will lose in relative ranking compared to China, India, Japan, Singapore, Mexico…
The ranking methodology used here weighed rankings in: Jiao Tong academic rankings, Essential Science Indicators, Google Scholar, Alexa (a measure of web site visits to universities) and The Times Higher World University Rankings.

Mystery of the Himalayas Solved:
If not for the surge, Sir Edmund Hillary and Sherpa Tenzing Norgay might have found themselves reaching the “roof of the world” by conquering Aconcagua (6,962m) in Argentina while Everest languished at a mere 6,848m above sea level, 2,000m below its actual peak. The discovery of the missing mantle - the cold, heavy rock beneath the crust - was revealed last week by Professor Wang-Ping Chen at the University of Illinois, whose team used more than 200 super-sensitive seismometers strung across the Himalayas, from India deep into Tibet.
…
But some scientists remain sceptical. One geologist at Cambridge, who wanted to remain anonymous because he hadn’t yet read Professor Chen’s paper, suggested that the slab could be the remains of the Tethys Ocean plate. Professor England counters that both the Asian and Indian plates have moved north since then

Today more and more locations are becoming viable for world class research and development. Today the following have significant ability: USA, Europe (many countries), Japan, Canada, China, Brazil, Singapore, Israel, India, Korea and Australia (I am sure I have missed some this is just what come to mind as I type this post) and many more are moving in that direction.
The continued increase of viable locations for significant amounts of cutting edge research and development has huge consequences, in many areas. If paths to research and development are blocked in one location (by law, regulation, choice, lack of capital, threat of significant damage to the career of those who would choose such a course…) other locations will step in. In some ways this will be good (see below for an explanation of why this might be so). Promising new ideas will not be stifled due to one roadblock.
But risks of problems will also increase. For example, there are plenty of reasons to want to go carefully in the way of genetically engineered crops. But those seeking a more conservative approach are going to be challenged: countries that are acting conservatively will see other countries jump in, I believe. And even if this didn’t happen significantly in the area of genetically engineered crops, I still believe it will create challenges. The ability to go elsewhere will make those seeking to put constraints in place in a more difficult position than 50 years ago when the options were much more limited (It might be possible to stop significant research just by getting a handful of countries to agree).
Debates of what restrictions to put on science and technology research and development will be a continuing and increasing area of conflict. And the solutions will not be easy. Hopefully we will develop a system of diplomacy that works, but that is much easier said than done. And the United States will have to learn they do not have the power to dictate terms to others. This won’t be an easy thing to accept for many in America. The USA will still have a great deal of influence, due mainly to economic power but that influence is only the ability to influence others and that ability will decline if diplomacy is not improved. Diplomacy may not seem to be a science and engineering area but it is going to be increasingly be a major factor in the progress of science and engineering. (more…)
Shanghai’s Jiao Tong University produces a ranking of the top universities annually (since 2003). The methodology used focuses on research (publications) and faculty quality (Fields and Nobel awards and citations). While this seems a very simplistic ranking it still provides some interesting data: highlights from the 2006 rankings of Top 500 Universities worldwide include:
Country representation in the top schools:
| location | Top 101 | % of World Population |
% of World GDP | % of top 500 |
|---|---|---|---|---|
| USA | 54 | 4.6% | 28.4% | 33.4% |
| United Kingdom | 10 | 0.9 | 5.1 | 8.6 |
| Japan | 6 | 2.0 | 11.2 | 6.4 |
| Canada | 4 | 0.5 | 2.4 | 8.0 |
| The rest of Europe | 18 | 4.4 | ||
| Australia | 2 | 0.3 | 1.5 | 3.2 |
| Israel | 1 | 0.1 | 0.3 | 1.4 |

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.

Lagging Engineer Degrees a Crisis by Kevin Hall:
I doubt that US universities are awarding more doctoral degrees than others are. Even if that is true I doubt it will last for even 5 more years. You might measure this in various ways including: absolute number of doctoral degrees awarded or using a per capita number. I believe several European countries are ahead today on a per capita basis. On an absolute basis I would be surprised if China or India isn’t already ahead. But if neither is, that will not true for long. I tried to find some good data online and wasn’t able to find anything certain in the time I took. Lost Dominance in Ph.D. Production sites a National Bureau of Economic Research report:
