IBM Fellow Grady Booch on the Value of Engineering?

In this webcast IBM Fellow Grady Booch discusses the critical role engineering plays in moving society forward. And he explores the history of science and engineering. This interesting webcast would be a good video to show children, or anyone, to bring out the desire to study engineering and encourage them to study so they can join the many engineers shaping our world and our future.

Innovation, America and Engineering: NAE Grand Challenges Summit

Innovation, America and Engineering: NAE Grand Challenges Summit in Raleigh, North Carolina:

Friday morning in Raleigh, a group of engineers from industry, academia and even government met to discuss the threat of America losing its global lead in innovation. The panel discussion was part of a Summit on the National Academy of Engineering Grand Challenges

Jeff Wadsworth, CEO and president of Battelle Memorial Institute, noted that high school graduation rates have fallen from about 86 percent in the Baby Boomer generation to about 72 percent today. He compared that to a 96 percent graduation rate in Denmark, 92 percent in Japan and the fact that China graduates three engineering students for every one that we do. It’s not news that international competition is stiffening against us, but the statistics he presented about how the U.S. measures up to foreign countries in K-12 metrics was gut-wrenching.

“Our historic lead in secondary education has disappeared,” Wadsworth said. “And as a leader of a large organization, I worry about education.”

Another panelist, Senator Ted Kaufman (D-Delaware) said the country was at a critical point in history. “We are in an economic war,” he said. “The future of our country rests on our ability to use STEM to solve problems.” Kauffman is the only sitting senator in Congress to have worked in the engineering field, and he repeatedly drummed out a message that policy could drive a solution to the STEM crisis.

A third panelist – John Chambers, chairman and CEO of CISCO – said he believed changing teaching methods in K-12 settings to be more collaborative, projects-oriented and skills-mastery oriented would be a good starting point.

the deans of the engineering colleges at both Duke and NC State universities announced today a new nationwide program targeting attracting school-aged children to the STEM fields. The Grand Challenge K-12 Partners Program will lean on engineering colleges throughout the U.S. to be resource hubs for K-12 students and teachers in their region.

Three more NAE Grand Challenge Summits are scheduled to take place next month, in Phoenix, Chicago and Boston. A fourth is scheduled for Seattle in May.

The importance of innovation and engineering education to long term economic success is one thing I believe strongly in and have written about here: Engineering Economic Benefits, Techonolgy Innovation Global Economy Changing, Centers of Technical Excellence and Economic Power. And is one reason I work for the American Society of Engineering Education (this blog is my own and not associated with ASEE).

Norway Reduces Infections by Reducing Antibiotic Use

Norway conquers infections by cutting use of antibiotics

Twenty-five years ago, Norwegians were also losing their lives to this bacteria. But Norway’s public health system fought back with an aggressive program that made it the most infection-free country in the world. A key part of that program was cutting back severely on the use of antibiotics.

Now a spate of new studies from around the world prove that Norway’s model can be replicated with extraordinary success, and public health experts are saying these deaths — 19,000 in the U.S. each year alone, more than from AIDS — are unnecessary.

“It’s a very sad situation that in some places so many are dying from this, because we have shown here in Norway that Methicillin-resistant Staphylococcus aureus [MRSA] can be controlled, and with not too much effort,” said Jan Hendrik-Binder, Oslo’s MRSA medical advisor. “But you have to take it seriously, you have to give it attention and you must not give up.”

The World Health Organization says antibiotic resistance is one of the leading public health threats on the planet. A six-month investigation by The Associated Press found overuse and misuse of medicines has led to mutations in once curable diseases like tuberculosis and malaria, making them harder and in some cases impossible to treat.

Now, in Norway’s simple solution, there’s a glimmer of hope.

Researchers Explain How Rotifers Thrive Despite Forgoing Sex

Bdelloid rotifers haven’t had sex for at least thirty million years. Most asexual animals are doomed to extinction. The excellent show, Science Friday, looks at the extraordinary adaptations that allow rotifers to thrive sex-free.

For millions of years, the rotifers have reproduced asexually, flying in the face of an idea known as the Red Queen Hypothesis, which states that without the advantage of sexual reproduction, more-rapidly evolving parasites and predators will eventually doom the asexual species. Now, the researchers studying the tiny organism say that its ability to dry up and blow away to greener pastures may have given the rotifers a hidden tactical edge in this evolutionary war.

The webcast provides a nice overview of the research. Every week Science Friday provides many such interesting reviews of recent scientific research.

What Are Rotifers?

Rotifers are small, mostly freshwater animals, and are amongst the smallest members of the Metazoa — that group of multicellular animals which includes humans, and whose bodies are organized into systems of organs.
Most rotifers are about 0.5mm in length or less, and their bodies have a total of around a thousand cells. This means that their organ systems are a greatly simplified distillation of the organ systems found in the bodies of the higher animals.

A typical rotifer might have a brain of perhaps fifteen cells with associated nerves and ganglia, a stomach of much the same number, an excretory system of only a dozen or so cells, and a similarly fundamental reproductive system. They have no circulatory system. It is an anomaly that despite their complexity, many rotifers are much smaller than common single-celled organisms whose world they share.

they are able to survive long periods — even perhaps hundreds of years — in a dried or frozen state, and will resume normal behaviour when rehydrated or thawed.
Secondly, they exhibit what biologists call cell constancy — they grow in size not by cell division, but by increase in the size of the cells which they already have.

According to the United Nations, more than 40 percent of Africans live in poverty, subsisting on less than US$1 a day. As co-founder and CEO of the nonprofit social enterprise KickStart, Fisher develops and markets moneymaking tools such as low-cost, human-powered irrigation pumps that improve the lives of small-scale rural farmers – the majority of the poor in sub-Saharan Africa.

“These poor rural farmers have one asset: a small plot of land; and one basic skill: farming. The best business they can pursue is irrigated farming,” Fisher explained. “Once they employ irrigation, the farmers can grow and sell high-value crops, like fruits and vegetables. They can grow year-round and reap four or five harvests, instead of waiting for the rain to grow a staple crop once or twice a year.”

Engineering Majors Hold 8 of Top 10 Highest Paid Majors

In August, employers responding to a NACE survey reported plans to trim their college hiring, hiring 7% for 2010 graduates from 2009. In addition, just 29% of those employers said they would increase their starting salary offers for the Class of 2010.

Most, but not all majors, experienced salary decreases. In fact, as a group, graduates with computer-related degrees (computer programming, computer science, computer systems analysis, and information sciences/systems) posted a 6.1% increase – the highest increase reported, which pushed their average up from $56,128 to $59,570. Among those earning a computer science degree, the average rose 4.8% to $61,205.

As a whole, engineering graduates also fared well. Their average salary offer as a group is up by 1.2% to $59,245. Although that increase is modest, engineering majors account for eight of 10 top-paid bachelor’s degrees in the Winter 2010 Salary Survey.

Slime Mold and Engineers Design Similar Solution

Slime Mold Grows Network Just Like Tokyo Rail System

Talented and dedicated engineers spent countless hours designing Japan’s rail system to be one of the world’s most efficient. Could have just asked a slime mold.

When presented with oat flakes arranged in the pattern of Japanese cities around Tokyo, brainless, single-celled slime molds construct networks of nutrient-channeling tubes that are strikingly similar to the layout of the Japanese rail system, researchers from Japan and England report Jan. 22 in Science. A new model based on the simple rules of the slime mold’s behavior may lead to the design of more efficient, adaptable networks, the team contends.

The yellow slime mold Physarum polycephalum grows as a single cell that is big enough to be seen with the naked eye. When it encounters numerous food sources separated in space, the slime mold cell surrounds the food and creates tunnels to distribute the nutrients. In the experiment, researchers led by Toshiyuki Nakagaki, of Hokkaido University in Sapporo, Japan, placed oat flakes (a slime mold delicacy) in a pattern that mimicked the way cities are scattered around Tokyo, then set the slime mold loose.

Initially, the slime mold dispersed evenly around the oat flakes, exploring its new territory. But within hours, the slime mold began to refine its pattern, strengthening the tunnels between oat flakes while the other links gradually disappeared. After about a day, the slime mold had constructed a network of interconnected nutrient-ferrying tubes. Its design looked almost identical to that of the rail system surrounding Tokyo, with a larger number of strong, resilient tunnels connecting centrally located oats. “There is a remarkable degree of overlap between the two systems,” Fricker says.

New Funding for arXiv Online Scientific Repository

The Cornell University Library is broadening the funding base for the arVix online scientific repository. Nearly 600,000 e-prints – research articles published online in physics, mathematics, statistics, computer science and related disciplines – now reside in arXiv, which is an open information source for hundreds of thousands of scientific researchers.

arXiv will remain free for readers and submitters, but the Library has established a voluntary, collaborative business model to engage institutions that benefit most from arXiv. “Keeping an open-access resource like arXiv sustainable means not only covering its costs, but also continuing to enhance its value, and that kind of financial commitment is beyond a single institution’s resources,” said Oya Rieger, Associate University Librarian for Information Technologies. “If a case can be made for any repository being community-supported, arXiv has to be at the top of the list.”

The 200 institutions that use arXiv most heavily account for more than 75 percent of institutional downloads. Cornell is asking these institutions for financial support in the form of annual contributions, and most of the top 25 have already committed to helping arXiv.

arXiv’s original dissemination model represented the first significant means to provide expedited access to scientific research well ahead of formal publication. Researchers upload their own articles to arXiv, and they are usually made available to the public the next day. arXiv, founded by physics professor Paul Ginsparg, has about 400,000 users and serves more than 2.5 million article downloads per month. Its 101,000 registered submitters live in nearly 200 countries.

arXiv is interconnected with many other scholarly information resources. These include the INSPIRE system being developed by supporting high-energy physics laboratories CERN, DESY, Fermilab and SLAC, as well as the Astrophysics Data System at Harvard University, another supporting institution. Read details about the operating principles of the new structure.

Bewick’s Swan Divorce

Experts stunned by swan ‘divorce’ at Slimbridge wetland

It is only the second time in more than 40 years that a “separation” has been recorded at the centre. Staff have described the new couplings as “bizarre”. It is not unheard of for the birds, which usually mate for life, to find a new mate but it tends to be because one of the pair has died, they said.

During the past four decades 4,000 pairs of Bewick’s swans have been studied at Slimbridge, with only one previous couple moving on to find new partners.

First suspicions of the rare event were raised when male swan Sarindi turned up in the annual migration from Arctic Russia without his partner of two years Saruni and with a new female – newly-named Sarind – in tow.

The pair’s arrival led conservationists to fear the worst for Saruni. But shortly afterwards Saruni arrived at the wetlands site – also with a new mate, Surune.

As for why they may have split, she said: “Failure to breed could be a possible reason, as they had been together for a couple of years but had never brought back a cygnet, but it is difficult to say for sure.”

Bewick’s swans are the smallest and rarest of the three species found in the UK and each individual can be identified by their unique bill pattern.
