Texas A&M University will pay an unprecedented $1 million in fines for more than a dozen safety violations in its research program on bioterrorism agents, the university announced today (February 20).

Who should the next US president appoint as director of the Office of Science and Technology Policy? That and more than 50 other science-related linkurl:positions;http://www.the-scientist.com/news/display/53457/ in the executive branch will more than likely be up for grabs come next January. The scientific community has already called for a linkurl:science debate;http://www.the-scientist.com/blog/display/54084/ by presidential candidates.

Geneticist Ray Wu dies
Alla Katsnelson | | 2 min read
Geneticist and genetic engineering pioneer Ray Wu died on February 10 of cardiac arrest. He was 79. In 1970, Wu developed a new location-specific primer-extension technique that became the first method of sequencing DNA. In the following decade, Frederick Sanger adapted the approach for faster sequencing, and received the Nobel Prize in Chemistry for the work in 1980. Wu's lab also devised other approaches that were used to analyze genetic sequences and to construct vectors for cloning genes,

Plant signaling gets complex

Last night's session (February 12) on hormones networks at the joint Keystone meeting on plant signaling and immunity in Keystone, Co, began with Charlie Chaplin. Specifically, the audience was treated to a video clip of the scene in Modern Times where Chaplin, a worker on a factory assembly line, becomes curious about the gears that drive the machinery, and to the horror of other workers, dives onto the assembly line and down the chute to explore. It was a clear metaphor for what's going on in

Autoimmunity in plants?
Alla Katsnelson | | 2 min read
Can plants suffer from autoimmunity? The term is generally reserved for organisms with an adaptive immune system, but one of the speakers last night at the Keystone meeting on plant signaling and immunity described a scenario that she called "the plant world version of autoimmunity." Farmers as well as plant researchers have long known that every once in a while, when two healthy plants are crossbred, the offspring (called F1) is inexplicably sickly - maybe its leaves are necrotic, or maybe it

The cell wall defense

What if our textbooks aren't quite correct, and the plant cell wall isn't just the purely structural organ it's thought to be?

The Sunshine Project, a Texas-based group that has monitored safety and oversight issues in research on bioterror agents, suspended operations on February 1, according to the group's linkurl:Web site.;http://www.sunshine-project.org/ Ed Hammond, who heads the non-profit operation and whom I've spoken with a handful of times, has gained a reputation as something of a pitbull tearing on the pantleg of the US's growing biodefense research program.

Lederberg: A thoughtful visionary

As a young lab leader at the University of Wisconsin in the 1950s, Joshua Lederberg and his first wife linkurl:Esther,;http://www.the-scientist.com/news/display/37394/ a microbiologist, would invite lab members to their home once a week to discuss significant recent advances in microbial genetics.

UK eases proposed stem cell rules

In response to a petition from researchers, the UK government has backed down on linkurl:restrictions;http://www.the-scientist.com/blog/display/54198/ to stem cell research proposed in a new bill. The revision of the Human Fertilisation and Embryology Bill, currently being debated in Parliament, stipulates that tissue donors must give explicit consent for use of their cells in embryonic stem cell research.

Paying for Patients

The international picture By Alla Katsnelson Related Articles Paying for Patients Different countries have different standards for paying clinical trial participants. In some places, says National institutes of Health's Christine Grady, a bag of rice or a bag of soap are considered more appropriate than cash. Institutional Review Boards (IRBs) say they try to translate US standards for payment into amounts appropriate for the region. The Human Subjects Commit

Paying for Patients How much should researchers pay clinical trial subjects? By Alla Katsnelson Related Articles 1 The wide range of payments, from $5 to $2,000 with a median of $155, also surprised her. "Everyone is worried so much about payment," says Grady, "but the amounts were pretty modest." The wide range of payments, from $5 to $2,000 with a median of $155, is surprising to Christine Grady.
