Biocomputing with Martyn Amos

The Jan 30th This Week in Science Podcast covers various topics including:

Today’s interview with Biocomputing expert, Martyn Amos, was a fascinating journey into the future of technology. What we consider computers today won’t be the computers of tomorrow, and computers will likely be integrated into all aspects of life using the miniaturization potential of DNA. While we are still far away from the realization of many aspects of biocomputing, it has come a long way from its humble beginnings.

Scientists and Engineers Without Borders

Building on the Doctors without Borders organization are two organizations: Science without Borders and Engineers without Borders.

Science Without Borders:

Scientists may not provide emergency relief in times of disaster, but the discipline has a major role to play in meeting the chronic needs of our planet: health, agriculture, environment, energy, and many more. By creating Scientists Without Borders, the Academy aims to facilitate synergies among institutions already committed to the UN Millennium Development Goals as well as to unleash the energy of thousands of scientists in academia and industry. With the benefit of the best and most current information, they can apply their efforts to training health workers and researchers in developing countries or devote part of their research efforts to address underserved global challenges.

Engineers Without Borders (USA):

The activities of EWB-USA range from the construction of sustainable systems that developing communities can own and operate without external assistance, to empowering such communities by enhancing local, technical, managerial, and entrepreneurial skills. These projects are initiated by, and completed with, contributions from the host community working with our project teams.

Educating the Engineer of 2020: NAE Report

Educating the Engineer of 2020:

The BS degree should be considered as a pre-engineering or “engineer in training” degree.

I am not convinced of this idea. It seems to me a BS degrees in engineering should be a full degree not some “pre” degree like pre-law. Obviously no engineering degree is an invitation to stop learning; life long learning is a requirement whether the engineering degree is earned in 4, 6, 8… years. Improving the life long learning methods is where effort should be focused in my opinion not in making the original degree take longer to earn.

The engineering education establishment should participate in efforts to improve public understanding of engineering and the technology literacy of the public and efforts to improve math, science and engineering education at the K-12 level.
NSF should collect or assist collection of data on program approach and student outcomes for engineering departments/schools so prospective freshman can

These seem like good ideas to me.

Other than trying to get people to buy the content that they provide for free I can’t understand why they present the material so poorly online. Once again basic web usability principles are lacking on their site.

Robots for Space Exploration

Robot Subs in Space James Vlahos:

But now, after spending nearly three decades on the margins of the space industry, Stone is closer than he’s ever been to proving that caves are the best earthly training ground for exploring space. Backed by a $5-million grant from NASA, he is developing a robot called DepthX that may turn out to be the most advanced autonomous underwater vehicle (AUV) ever. Like its inventor, DepthX is a caver, capable of navigating constrained, obstacle-filled environments. Its theoretical mission, though, is bold even by Stone’s standards: a hunt for extraterrestrial life on the Jovian moon of Europa.

A ‘Chunnel’ for Spain and Morocco

From the bustling waterfront of this African port city, Europe appears tantalizingly close: The coast of Spain shows on the horizon just nine miles away. Despite decades of dreaming, no one has been able to bridge the physical divide that opened between the two continents more than 5 million years ago, forming the geological bottleneck to the Mediterranean Sea.

In recent months, however, the governments of Morocco and Spain have taken significant steps to move forward with plans to bore a railroad under the muddy bottom of the Strait of Gibraltar. If built, the project would rank among the world’s most ambitious and complex civil engineering feats, alongside the Panama Canal and the Channel Tunnel between Britain and France.

More Microchip Breakthroughs

Intel, IBM separately reveal transistor breakthrough

In dueling announcements, Intel Corp. and International Business Machines Corp. separately say they have solved a puzzle perplexing the semiconductor industry about how to reduce energy loss in microchip transistors as the technology shrinks to the atomic scale.

Each company said it has devised a way to replace problematic but vital materials in the transistors of computer chips that have begun leaking too much electric current as the circuitry on those chips gets smaller. Technology experts said it’s the most dramatic overhaul of transistor technology for computer chips since the 1960s
…
The problem is that the silicon dioxide used for more than 40 years as an insulator inside transistors has been shaved so thin that an increasing amount of current is seeping through, wasting electricity and generating unnecessary heat. Intel and IBM said they have discovered a way to replace that material with various metals in parts called the gate, which turns the transistor on and off, and the gate dielectric, an insulating layer, which helps improve transistor performance and retain more energy.

Entrepreneurial Engineers

Business Leader Says Today’s Engineers Have to Be Entrepreneurial:

“Every engineer and scientist entering the job market today needs to be entrepreneurial, whether or not they plan to start their own business,” says Donna Novitsky, partner at venture capital firm Mohr Davidow Ventures and adjunct professor in the School of Engineering. “It’s no longer an optional job qualification. It’s a ticket to entry in leading companies, even for undergrads.”

Strong words. A great resource mentioned in the article Stanford Technology Ventures Program Educators Corner, includes a large number of podcasts and short (2 – 10 minute video webcasts):

Stanford Technology Ventures Program (STVP) Educators Corner is a free online archive of entrepreneurship resources for teaching and learning. The mission of the project is to support and encourage faculty around the world who teach entrepreneurship to future scientists and engineers, as well as those in management and other disciplines.

Feedback Within the Context of Systems Theory

Good read – Lengthening the Feedback Loop: A History of Feedback Within the Context of Systems Theory by Julia Evans:

Once you start looking for feedback loops, you see them everywhere. As I write this, my refrigerator clicks on, reminding me that negative feedback from its thermostat is responsible for keeping my food from spoiling.
…
The purpose of this paper is to show how feedback developed from an engineering principle to part of a unifying theory that helps to shape the way we look at the world. I will trace the concept of feedback through history within the broader framework of systems theory, and demonstrate how it is being applied to business, economics, and society at large.

The Dynamics of Crowd Disasters: An Empirical Study

Interesting paper – The Dynamics of Crowd Disasters: An Empirical Study (also see the supplemental materials). Systems thinking allowed the engineers to design a solution that wasn’t about enforcing the existing rules more but changing the system so that the causes of the most serious problems are eliminated.

analysis of unique recordings of the Muslim pilgrimage in Mina/Makkah, Saudi Arabia. It suggests that high-density flows can turn “turbulent” and cause people to fall. The occuring eruptions of pressure release bear analogies with earthquakes and are de facto uncontrollable.
