The creators of Botnet Judo, thanks to their work on Storm, decided that the use of templates might provide an opportunity to recognize any spam based on the same template. Since normal e-mail would be very unlikely to match a template by chance, this method should have a very low false-positive rate, where a legitimate message is recognized as spam.

Liangfang Zhang, the second author on the "nanoburr" paper in last week's PNAS that has received alot of attention is now a professor in the Department of NanoEngineering at the Jacobs School.CAMBRIDGE, Mass. — Researchers at MIT and Harvard Medical School have built targeted nanoparticles that can cling to artery walls and slowly release medicine, an advance that potentially provides an alternative to drug-releasing stents in some patients with cardiovascular disease.
The particles, dubbed “nanoburrs” because they are coated with tiny protein fragments that allow them to stick to target proteins, can be designed to release their drug payload over several days. They are one of the first such targeted particles that can precisely home in on damaged vascular tissue, says Omid Farokhzad, associate professor at Harvard Medical School and an author of a paper describing the nanoparticles in the Jan. 18 issue of the Proceedings of the National Academy of Sciences.
Researchers at UC San Diego who last year genetically engineered bacteria to keep track of time by turning on and off fluorescent proteins within their cells have taken another step toward the construction of a programmable genetic sensor. The scientists recently synchronized these bacterial “genetic clocks” to blink in unison and engineered the bacterial genes to alter their blinking rates when environmental
conditions change.
Their latest achievement, detailed in a paper published in the January 21 issue of the journal Nature, is a crucial step in creating genetic sensors that might one day provide humans with advance information about temperature, poisons and other potential hazards in the environment by monitoring changes in the bacterium’s blinking rates. Watch a video showing the UCSD team’s blinking genetic clocks here.
“Programming living cells is one defining goal of the new field of synthetic biology,” said Jeff Hasty, associate professor of biology and bioengineering at UCSD who headed the research team with Lev Tsimring, associate director of UCSD’s BioCircuits Institute.
I know that many of you have been moved, as I have, by the stories and images emerging from Haiti in the wake of last week’s devastating earthquake. We all want to do something to help. Rest assured that Global TIES intends to help Haiti rebuild itself, once it is safe and appropriate for us to be on the
ground.
In the meantime, the best way to help is through financial contributions. Immediate medical aid is urgently needed to stem the death toll from this disaster. To this end, Global TIES has teamed up with Partners in Health, a non-governmental organization co-founded by Dr. Paul Farmer that has been providing healthcare in Haiti for the past 25 years. (To learn more about Dr. Farmer and his groundbreaking work, read “Mountains Beyond Mountains” by Tracy Kidder.)
Global TIES has created a fund-raising page on the Partners in Health web site: http://act.pih.org/page/outreach/view/haitiearthquake/ucsdglobalties.
Please join me in giving what you can via this web site. Partners in Health has agreed to track contributions made from UC San Diego via this site, so if you are part of the UC San Diego community, please include your UCSD email address on your donation form. All proceeds will go to Partners in Health.
"In Haiti, we are dealing with structures that are similar in a way to the construction we used to do 100 years ago here in the U.S.," said Jose Restrepo, professor of structural engineering at UCSD. "Those are structures that do not incorporate any seismic design provisions that are very precarious where they are built."
Restrepo talked to 10News about seismic advances being made in schools throughout the University of California system. "Every one of us chips in and we are working in a collaborative environment to see what is best for our region and trickle down to all the regions in the world," he said.
Inspired by overheard snippets of cell phone conversations that most people
would ignore, Wendy Richmond and collaborator Michael Chladil have taken
background noise and turned it into interactive artwork.
"Overheard" opens Jan. 15, 2010 and runs through March 12, 2010 at the gallery@calit2. The installation consists of multiple displays of textual graphics, based on overheard New York City cell phone conversations ranging in subject matter from the poetic to the banal. The audio, made up of recordings of conversations spoken by actors, is triggered as the audience moves through the gallery space. In addition, two interactive rope&pulley systems allow visitors to interface with the displayed graphics, changing their shape and size. The visual elements of the fragmented conversations continue onto the gallery display walls on the first floor of Atkinson Hall. The artists hope that the installation will provide viewers an opportunity to reframe the barrage of private and public expression that they navigate in their everyday lives.

High school teachers are invited to attend an exciting new TeacherTECH workshop series focused on biotech. This series will provide building blocks needed to introduce standards-based, hands-on laboratory activities into your lesson plans. May be used as stand-alone activities or as a combined series of labs to create an entire biotechnology course. The first of this eight-part series will focus on quick, easy ways to teach the principles of chromatography, a powerful method for separating complex mixtures into component parts based on molecular properties. We will extract the DNA from your own cheek cells, and then watch it precipitate. Bring only your imagination and take home your own DNA - in a necklace! Teachers may choose to attend one or all of the workshops in this series, depending on their interest. Please contact Ange Mason via email or at 858-534-5064 for more details.
