Mixing Science and Politics This article1 seemed to be a well-researched and written update on the action by some European scientists. I understand that the purpose of the article was not to air the motives of those people, but the question begs itself, and intended or not, the message it sends is that the boycotters have high moral ground, that the conflict and bloodshed and suffering in the area are all Israel's doing. Paragraph after paragraph, those activities are examined as perhaps h

Arbitrarily Meaningful No need to feel guilty about dropping the ball on "Xerox."1 The term is indeed arbitrary and meaningless in the only meaningful way possible; that is, legally with respect to trademarks. Xerox is not a term commonly used, either now (but for Xerox's use of it) or in classical times. While "xerography" may technically mean "dry writing," Xerox is no less fanciful than whatever would be the term for thin film, as derived by combining words that never have been used in t

Dumbocracy Examples of public "demagoguery" that you quote in your editorial1 are quite conspicuous. Unfortunately, your appeal to "our most eminent researchers" to "lead the debates on the scientific merits of stem cells" in existing situations will only make things worse; that is, decisions less rational and public confidence more abused. The problem is that "our most eminent researchers" are mostly a thoroughly corrupt crowd, who put their personal financial interests, including gains in

More than half, 57%, bustle about in the kitchen nearly every day.

Frontlines | Standing Guard--Inside the Zoo Erica P. Johnson With monkeypox a reality in the United States and SARS (severe acute respiratory syndrome) perhaps only several sneezes away, it makes sense to use zoo animals, which are checked regularly for health problems, as sentinels to monitor public health threats from zoonotic (animal to human) organisms. After birds were found dead from West Nile virus (WNV) in New York zoos in 1999, the Zoo Network was established to monitor zoo animal

Carlson An Anglo-French research team has created a chicken with teeth, shedding new light on the signaling mechanisms that underlie cell differentiation in organ development. Chicken embryos were implanted with murine cells that constitute teeth and parts of the head, which resulted in the development of tooth-like structures not found in any bird.

Foundations | The Holy Grail of Immunology Click for larger version (27K) In 1983, Tak Mak's lab cloned the beta chain of the T-cell receptor, helping to accomplish what the immunology community had been anticipating for 20-plus years. But the T-cell receptor's structure was believed to be heterodimeric, and no one had deciphered what the other piece looked like. In 1984, Mak sketched his thoughts on its shape for a student, Pamela Ohashi, who then made antibodies to peptides, using the a

He skipped the "What-should-I-do-with-my-life" angst, knowing since grade school that he wanted to be a scientist. And when he mixed ammonia and bleach in his own little lab in his parents' basement, no life or property was lost. He met his lifelong partner, Carol, in an organic chemistry class at Grinnell College in Iowa. After

5-Prime | Whisper Down the Vine: Plant Communication What is chemical communication in plants? Plants rely on chemical signals to communicate with each other and themselves. Some of these chemicals are volatile (known as volatile organic compounds--VOCs) and can be released from leaves, fruits, and flowers. VOCs play various roles in plant development, survival, and gene expression. What sends and receives these signals? Three main types of plant-to-plant signaling are known: interspecifi

The discovery of cyclooxygenase (COX) isoforms, COX-1 and COX-2, in the early 1990s helped explain how non-steroidal anti-inflammatory drugs (NSAIDs) work and led to specific agents with fewer gastrointestinal side effects.

PATENT WATCH | RNA Interference without the Interferon The red-hot field of RNA interference (RNAi) could benefit from patents issued jointly to Queensland, Australia-based Benitec, and the State of Queensland (US patent 6,573,099, issued June 3, 2003, and UK patent 2353282, granted May 3, 2003). The patents describe a method Benitec calls "DNA-directed RNA interference" (ddRNAi) to differentiate it from typical double-stranded small interfering RNA (siRNA). Using this method, a DNA constru

In response to scrambled protein signaling pathways, certain cells turned cancerous and grew into tumors that took over the 37-year-old woman's ovaries. Though her doctors settled on a diagnosis of ovarian cancer, they could not determine what kind of neoplasia was causing the tumor growth--an important factor in determining the proper treatment.

Courtesy of Invitrogen Scientists studying a protein's function frequently start with the gene that encodes it. "You want to know what a protein does at the biochemical, cellular, physiological, and organismal levels," says Marc Vidal, assistant professor of genetics at Harvard University and research associate at the Dana-Farber Cancer Institute. "To do that, you need to express this protein under many different conditions using the region of the gene that encodes it, and that's the open read

One of the challenges of proteomics is sample size. Researchers need to fractionate complex protein mixtures into their component parts for subsequent analysis, but the miniscule quantities and volumes involved preclude standard large-scale chromatography. Three years ago Agilent Technologies, headquartered in Palo Alto, Calif., introduced its 1100 series capillary LC system, featuring tiny tubes that could pump nanoliter volumes through columns with high accuracy. Now the company is following

TIP TROVE | Traveling on a Light Budget Courtesy of NIH Traveling on a budget isn't much different for researchers than when they were students. For trips of a relatively short duration, going by train instead of plane offers benefits such as less time required to check in, and more room for paperwork while en route. Sharing a hotel room with a peer can result in significant savings. Although many now use the Web for travel arrangements, consider soliciting recommendations from a travel age

But with talent, experience, and enormous focus and discipline, the big wall becomes a series of small, concentrated moves.

When universities license discoveries made by scientists to companies for commercialization, the whims of the marketplace determine the results. As with anything else in business, the odds of scoring a major financial hit are slight, but the payoff can be exceedingly large. This is especially true for the life sciences, where discoveries and patents in medicine and biology continue to produce the lion's share of revenues for universities and research institutions. Life science patents also co

The rigor scared Stephen Hoffman. He had felt irritable and feverish all morning in his hotel room. Then, in the midst of a presentation at a meeting of the American Society for Clinical Investigation, he began to shake uncontrollably. Ironically, the subject of that presentation was whether the antibodies elicited by the vaccine he had helped develop would prevent malaria. To prove it would work, he and six of his coworkers took the vaccine and then exposed themselves to the bites of malaria

Each time Susan Fahrbach walks into her dank, windowless lab, she returns to the past. "We have dingy, cinderblock walls that give a 1960s feel to our work environment, which is probably the last time they've been painted," explains the professor of entomology at the University of Illinois, Urbana-Champaign. A working environment like Fahrbach's can be a huge disadvantage for recruiting. "I had a visitor from Europe ask me why my building looked like a prison," says Fahrbach. "This isn't the

Ignorance and commercial interest make a combustible mixture, with enlightenment often a victim of the fumes. Views tend to polarize and become unduly influenced by those best able to manipulate the media, irrespective of the argument's merits. The result can be an alarming disparity between public opinion and the true state of the science. No doubt, this syndrome has adversely affected debate over big issues such as genetic modification of plants and global warming. The question is, what's

As my intrepid colleague Sam Jaffe reports in this issue (Rebuilding Iraqi Science), Iraqi science is on its knees. Following two-and-a-half decades of a brutal dictatorship, it's been pummeled by sanctions, halted in its tracks by war, and ransacked in the postwar chaos. We probably can add to this list a deep malaise, which appears to be affecting the entire country as it awaits reconstruction. While reading his report, several questions struck me: Just how worthwhile would it be to reconst

Ned Shaw If the 20th century will be remembered for outer space exploration and the human genome, the 21st century, I believe, will be known as the "Brain Century." Although voluminous literature has appeared about the brain and its attribute, the infinite mind, our knowledge is still infinitesimal. From the knowledge to date and forthcoming, I foresee that we will, within this century, begin to learn how our frontal cortex, through focused thought, can treat physiological disorders. This woul
