NSF Cafe Scientifique: Arlington, Virgina

Cafe Scientifique NSF. Where: The Front Page, 4201 Wilson Blvd, Arlington, Virginia (Ballston Metro stop). 6:30PM-8:00PM presentation, followed by Q&A: The “Shocking” Science Behind Electric Cars:

Science makes many things possible, including alternative fuels and modes of personal transportation… Goldstein and Garlow are the President and VP of the DC area Electric Vehicle Association. They will discuss the science behind electric cars, such as fuel cells and battery technology, and some of the issues surrounding their use and acceptance. And, they will bring actual cars to touch and explore, including the MIT entry into the 1994 Tour de Sol, an electric car that is solar-powered, and an all-electric Toyota RAV4.
…
Cafe Scientifique flourished first in the U.K. as a way for the public and scientists to mingle and discuss science issues in an informal setting. At least 35 cafés now exist in the U.S.

I hope to make it this month.

FDA May Make Decision That Will Speed Antibiotic Drug Resistance

FDA Rules Override Warnings About Drug:

The government is on track to approve a new antibiotic to treat a pneumonia-like disease in cattle, despite warnings from health groups and a majority of the agency’s own expert advisers that the decision will be dangerous for people. The drug, called cefquinome, belongs to a class of highly potent antibiotics that are among medicine’s last defenses against several serious human infections. No drug from that class has been approved in the United States for use in animals.

This is why it is so important for government decisions that require scientific knowledge be made by knowledgeable scientists.

But Sundlof said that under FDA rules, those decisions must be left up to veterinarians unless there is clear evidence that wider use is causing harm.

“That is our policy” is not a good excuse for endangering public health. The dangers of anti-biotic resistance are obvious, well known, we see the results of bad decisions in the past creating havoc today and still government wants to act as though the inevitable consequences of their actions are somehow out of their hands. A policy that will lead to the deaths of many people should be fought. If you want to claim this policy will not do that, then make that argument. Don’t claim some policy prohibits you from saving lives.

Democratic/Republican forms of government give politicians oversight over bureaucracy to guide decisions for the public good. When politicians don’t understand basic science (in this day and age – when decisions require that understanding) that can lead to very dangerous policies. You would think that adults would be able to understand that just because consequences will be delayed a few years that doesn’t mean you should allow special interests to get what they want today. But the deficit (nearly $8,800,000,000,000 for the federal government now) provides a visible sign how much they care about future consequences of their actions. Combine that with little scientific understanding and that is not a prescription for good decisions.

European Innovation Scoreboard

European Innovation Scoreboard (pdf)

The US and Japan are still ahead of the EU25 in terms of innovation performance, but the innovation gap between the EU25 and Japan, and in particular with the US is decreasing (see Figure II). The EU25 has improved its relative performance compared to the US in S&E graduates, tertiary education, business R&D, early-stage venture capital, medium-high and high-tech manufacturing employment, EPO patents, USPTO patents and community trademarks. The EU has improved its relative performance compared to Japan mostly in S&E graduates and broadband penetration rate.
…
Sweden, Switzerland, Finland, Denmark, Japan and Germany are the innovation leaders, with SII scores well above that of the EU25 and the other countries…
The US, UK, Iceland, France, Netherlands, Belgium, Austria and Ireland are the innovation followers, with SII scores below those of the innovation leaders but above that of the EU25 and the other countries.

NSF Summer Institute on Nano Mechanics and Materials

NSF Summer Institute on Nano Mechanics and Materials is offering short courses this summer, one at Northwestern and one at UCLA. NSF fellowships are available to professors, high-school science teachers, post-docs and Ph.D. candidates from US universities. The fellowship consists of full tuition plus a travel allowance, if applicable. Apply by April 1, 2007. I really like that the NSF provides funds to help people attend this type of thing.

The objectives of the NSF Summer Institute on Nano Mechanics and Materials are:

* To identify and promote important areas of nanotechnology, and to create new areas o focus which will augment current nanotechnology research and development by universities, industries and government.
* To train future and practicing engineers, scientists and educators in the emerging areas of nanotechnology, nano-mechanics, and nano-materials.
* To exchange new ideas, disseminate knowledge and provide valuable networking opportunities for researchers and leaders in the field.

The short courses offered by the Institute provide fundamentals and recent new developments in selected areas of nanotechnology. The material is presented at a level accessible to BS graduates of science and engineering programs. Emphasis is on techniques and theory recently developed that are not available in texts or standard university courses.

Atom-thick Carbon Transistor

Atom-thick carbon transistor could succeed silicon by Tom Simonite:

Transistors more than four times smaller than the tiniest silicon ones – and potentially more efficient – can be made using sheets of carbon just one-tenth of a nanometre thick, research shows. Unlike other experimental nanoscopic transistors, the new components require neither complex manufacturing nor cryogenic cooling.

The transistors are made of graphene, a sheet of carbon atoms in a flat honeycomb arrangement. Graphene makes graphite when stacked in layers, and carbon nanotubes when rolled into a tube. Graphene also conducts electricity faster than most materials since electrons can travel through in straight lines between atoms without being scattered. This could ultimately mean faster, more efficient electronic components that also require less power.

How to Deal with False Research Findings

The Science of Getting It Wrong: How to Deal with False Research Findings by JR Minkel adds to our recent spate of posts on drawing faulty conclutions from data (such as: Correlation is Not Causation, Cancer Deaths – Declining Trend?, Seeing Patterns Where None Exists, Karl Popper Webcast).

In his widely read 2005 PLoS Medicine paper, Ioannidis, a clinical and molecular epidemiologist, attempted to explain why medical researchers must frequently repeal past claims. In the past few years alone, researchers have had to backtrack on the health benefits of low-fat, high-fiber diets and the value and safety of hormone replacement therapy as well as the arthritis drug Vioxx, which was pulled from the market after being found to cause heart attacks and strokes in high-risk patients.

Using simple statistics, without data about published research, Ioannidis argued that the results of large, randomized clinical trials—the gold standard of human research—were likely to be wrong 15 percent of the time and smaller, less rigorous studies are likely to fare even worse.

Among the most likely reasons for mistakes, he says: a lack of coordination by researchers and biases such as tending to only publish results that mesh with what they expected or hoped to find. Interestingly, Ioannidis predicted that more researchers in the field are not necessarily better—especially if they are overly competitive and furtive, like the fractured U.S. intelligence community, which failed to share information that might have prevented the September 11, 2001, terrorist strikes on the World Trade Center and the Pentagon.

But Ioannidis left out one twist: The odds that a finding is correct increase every time new research replicates the same result, according to a study published in the current PLoS Medicine.

$60 Million in Grants for Universities

HHMI Invites Colleges to Compete for Grants to Strengthen Undergraduate Research, Mentoring, Computational Skills:

Institutions are invited to compete based on their proven records in preparing undergraduates for graduate education in science and for careers in scientific research and medicine. In the past, the top 200 colleges were invited to apply. This year, to increase the pool of applicants, the Institute invited the 226 colleges with the highest percentage of graduates, including underrepresented minorities, who go on to graduate or medical school. For the first time, invited institutions include a Native American tribal college.

A panel of leading scientists and educators will review the applications and make recommendations to the HHMI undergraduate science education grants staff. Awards will be announced in May 2008.

Through its Undergraduate Science Education Program, HHMI has awarded $235.8 million in grants to 126 colleges throughout the United States and Puerto Rico since 1988, part of $693 million in grants for undergraduate science education that the Institute has awarded to institutions of higher education, including research and doctoral universities. HHMI is the largest private supporter of science education in the United States.

This is a huge amount of money that can do a great deal of good.

Editorial: Engineers of the Future

Engineers of the future:

Technology education programs at all grade levels seek to afford students opportunities to tinker, to discover how things work, and to explore the designed world. At the elementary school level, students may learn about simple machines designed for specific tasks or about the basics of electricity by actually building simple circuits. In middle school, students may explore concepts in more detail, perhaps by designing and building a model of a bridge or a gliding aircraft. In high school, students may have opportunities to design an affordable home, take something apart to see how it works, or design and build a robot that would be used for a rescue mission or some other specific purpose. All of these experiences are related to the processes of engineering.

This is the type of learning that can enhance a future engineer’s experience, but also the type that cannot be included in the typical upper grade level math or science classroom for one main reason: math and science teachers generally do not have the time and may not have the interest or expertise needed for in-depth study of technology.

The editorial makes a good point. As import and primary science and math education are they are not enough. Effort to create an environment where students can experiment and use their hands and minds to solve problems is incredibly valuable. Teaching in this way is not as simple as it might seem, see example below for some ideas and resources that can help create these type of learning institutions.
