So much happens in research it's impossible to keep up with it all, and some neat discoveries go underreported. So I'm directing your attention to a pair of complementary findings about DNA transcription -- a rather fundamental issue for the biological sciences.
A few weeks ago, a "rewind" motor for DNA was described by UCSD scientists James Kadonaga and Timur Yusufzai
. This protein… Continue

Hello, science-minded folks,
You're looking to inform people about science and to exchange ideas. Quelle coincidence! I just happen to work for a San Diego newspaper that can spread that information. And I'm looking for ideas and contacts.
I'm Bradley Fikes, the business and sci-tech writer for the North County Times, in San Diego and Southwest Riverside counties. I just joined yesterday, but plan to be a frequent presence here. Our Web is at… Continue

The US has shown a long standing lead in computer technology at the high end. New players in Europe and Asia are looking to potentially dethrone the US as the leader in the fastest supercomputer. The current leader, IBM currently has a machine at Los Alamos that can perform 1.1 petaflops--about a million times faster than a decent desktop personal computer. Because of the ever falling price of CPUs, it is now possible to built supercomputers at a much… Continue

I don't think I could describe this better than the folks at Science Now so here ya go:
"Six weeks ago, the Gonzo Scientist challenged researchers around the world to interpret their Ph.D. research in dance form, film the dance, and share it with the world on YouTube (Science, 10 October, p. 186). By the 11 p.m. deadline this past Sunday, 36 dances--including solo ballet and circus spectacle--had been submitted online. A panel of nine judges--the three winners of the first "Dance… Continue

As part of an excellent graduate student seminar series at the Salk Institute, I gave a talk today addressing some of the research related to spinal cord injury. As promised in the talk, I have posted here the main websites I used to gather information and the list of references I cited in the talk.
• Christopher & Dana Reeve Foundation
• University of Alabama Spinal Cord… Continue

So the other night, I was channel surfing when a confusing commercial interrupted the comfy brain numbing sensation television usually provides.
It featured Noah Whyle (sp?), who was on the show ER a decade ago, blathering on about the WWF and Polar Bears. He mentioned the WWF a number of times and the imagery showed polar bears swimming from small patches of ice and the letters "WWF" were featured prominently on the screen.
I admit I was a bit confused. I'm aware of the… Continue

Dr. Steve Kay (Dean of the UCSD Division of Biological Sciences and member of the National Academy of Sciences) recently gave a lecture at the UCSD Biomedical Library in which he provided a broad overview of the environmental, economic and security issues surrounding the need to generate transportation fuels from biomass in a sustainable fashion.
This lecture is now available online

The Willow Grove Elementary School in Santa Luz (Poway school district) had a Family Science Night Nov 14, 2009 that drew about 750 people to 8 tables of hands-on science experiments.
Lead by Event organizer Dr. Tanya Moreno, PTA Chair Zoom Duong, and Principal Cindy De Clerc:
We had tables the physics of spinning chairs, dropping balls, extracting DNA, aerodynamics, polymers, fluorescence, a microscopic look at frogs eggs and embryos, and of course,… Continue

FREE WATERSHED PRESENTATIONS FOR HIGH SCHOOL STUDENTS IN UNINCORPORATED SD COUNTY!
This year we have partnered with the County of San Diego to give free classroom presentations to high school students in the unincorporated areas of the County. These presentations focus on local watersheds, explain the difference between storm water and waste water, and identify everyday actions students can take to keep their local watershed healthy. Our… Continue

Because it costs $15,000 per pint to bring water into space, NASA developed a system that can convert other um...'fluids' into drinkable water. NASA sent "jars of sweat" to researchers asking them to get drinkable water from this other less thirst-quenching sources of water.
This example of pushing technology and our perceptions of clean water sources has huge Earth-bound implications. In 2006, waterborne diseases were estimated to cause 1.8 million deaths each year while about 1.1… Continue

After surviving far longer than expected, the Phoenix Mars Lander ground to a halt a few days ago, probably for good.
The Phoenix landed on Mars in May to analyze the soil of the planet's northern arctic plans, and outlived the timeline for its mission...twice! $428 million well spent. If only the financial industry used its funds so effectively.…

Earlier this week biologists in Japan published results showing they cloned mice that have been dead and frozen for 16 years. This was big news because, until now, scientists have only been able to clone animals from cells taken from living animals.
Of course the speculation now goes to the next level, can we clone extinct species?
The answer? Probably.
But does this seem like a really bad idea to anyone else?
Not that I’m worried about getting eaten… Continue

This headline has been splashed across all major media outlets as of yesterday morning when it was announced the popular speculative fiction author lost his battle to cancer.
"The master of the "techno thriller," Michael Crichton, has died at the age of 66. He was battling cancer. Crichton was best known for scary stories of science gone wrong in popular books like The Andromeda Strain and Jurassic Park."
They include a recent interview with the author… Continue

Three neat article appearing on the ScienceDaily website from yesterday and today. The first is about how the brain prevents verbal errors.
From the article:
"The researchers showed that the brain responds to such faulty utterances with a specific electrophysiological signal. It was already known that this wave occurs when making behavioural errors, such as pressing a wrong button by accident. This wave, called Error-Related Negativity, is informally known as the 'Oh-shit'… Continue
