Contributors

Contributors Stanford molecular biologist Suzanne Pfeffer studies how receptors are transported through human cells and end up in just the right place at the membrane. She specializes in Rab GTPases, the enzymes that orchestrate much of this activity. Currently, her lab is focusing on the functioning of the Golgi apparatus, the cell’s packaging and distribution center. “The Golgi’s a really important structure in the cell, and despite d

Naturally Selected

By Sarah Greene Naturally Selected Ninety thousand ways to make you smarter. Can the molecular biologist afford to ignore developments in systems biology, bioinformatics, structural biology, and now even physics? Many thanks to readers who responded to my inaugural editorial (in the February issue), calling for feedback on the “next new thing.” To some, the thing was the t-shirt (we’re working on that), othe

Mail

Mail Do Fish have Personalities? Re: “Odd Man Out,”1 animals don’t have personalities since they are not persons. But individuals in many species (most, all?) differ from one another in the way they behave. If you do a behavioral experiment on rats, they will differ in how they respond, and the differences are in some situations consistent across tests that measure similar characteristics (like fear responses). So the rats diff

Bio and the city

By Bob Grant Bio and the city © Brett Hillyard On more than one occasion, Chicago-area police have pulled researcher Stan Gehrt out of the truck he drives around the area. Often, they are acting on tips from wary community members, who report his vehicle—topped by large radio telemetry antennae and driving through neighborhood streets in the wee hours of the morning—as suspicious. “We have to assume the position [hand

Catch of the day

By Amy Coombs Catch of the day © Greg Lynch Even discriminating sushi connoisseurs would envy the tuna George Amato has sampled. The purpose of the tasty experiment: Use DNA barcoding to find out if threatened species of tuna are sold in the United States market. Barcoding relies on a short fragment of mitochondrial DNA found in virtually all living things. The 650 base-pair region, part of the cytochrome oxidase I (COI) gene, accu

Once bitten

An intense heat washed over my body, my head throbbed, my neck muscles ached, and I tried desperately to stretch the flimsy airline blanket over my chill-wracked arms and legs. All because of a South African tick—o

Evolution of science

By Lauren Urban Evolution of science Science is made up of cliques. Throughout Alex Shneider’s career, he has noticed certain people drawn to certain types of science, and certain types of grant proposals always being funded. Shneider, the founder and CEO of Cure Lab, a vaccine biotech based in Massachusetts, came up with a theory to explain why these cliques occur. At first, it wasn’t too popular. Shneider concluded that a certain type

The Garden of Antimicrobial Delights

By Julian Davies The Garden of Antimicrobial Delights Major advances in genomics, cloning, and chemistry will restock the dwindling supply of effective antibiotics, but we can’t depend on big pharma and biotech.

Almost all papers and reviews dealing with infectious diseases stress that new classes of antibiotic

Keep it Simple

By H. Steven Wiley Keep it Simple Telling a simple story about your data is the easiest way to get funded—and it’s one of the hardest things to do. The big and simple stories attract ample funding and top scientific talent, whereas the complex stories remain mostly ignored in specialty journals. One common piece of advice I frequently give to young scientists is to always tell a story with their data, because it’s a us

Dangerous Liaisons

Death Star

How Does Your Golgi Go?

By Suzanne R. Pfeffer How Does Your Golgi Go? Science is shedding new light on the functioning of the cell’s protein processing complex. © Biophoto Associates / Photo Researchers, Inc. Scientists have long sought a robust picture of how the Golgi complex, an organelle critical to the post-translational modification and sorting of newly synthesized proteins, operates. The Golgi contains multiple subcompartments—cis (earl

Wallace's lost chest, circa 1848

By Edyta Zielinska Wallace’s lost chest, circa 1848 When Bill Wallace, great grandson of famed naturalist Alfred Russel Wallace, was growing up, he would put on his great grandfather’s hat and finger a cabinet that his family considered “a bit of a shrine to Wallace,” Bill recalls. By that time, the family had sold most of Wallace’s collections, but had kept the cabinet—one of two that housed the naturalist’s specimens.
