By Sarah Greene The Next New Thing Our conversation is about to get a lot more interesting. Can we invigorate science through greater interactive behavior? Way before Facebook, scientists and readers of science—pioneers by nature—were establishing their own brand of participatory media. Twenty-two years ago, when Fred Ausubel and colleagues at Massachusetts General Hospital and Harvard Medical School were formulating the lab manual Curr

Contributors Kai Simons began researching cell membrane biology in the 1960s and 70s as a postdoc at Rockefeller University in New York, and he’s never looked back. “The field [is] at the crossroads of protein and lipid biochemistry, as well as cell biology and biophysics,” making it a challenging—but exciting—area to work in, says Simons, director emeritus at the Max Planck Institute of Molecular Cell Biol

Mail Speak Your Mind Steven Wiley’s article about the lack of willingness to debate1 is an excellent description of the current state of culture in biology. Perhaps the most important comment in the article is “Besides, why should anyone respect an opinion that even the author is not willing to claim?” Given the evident truth in this statement, are the excuses for keeping peer review anonymous really paramount? Colin Anderson Univer

When postdoc Usama Al-Atar returned to retrieve his worms after an hour of incubating them with a photo-controlled molecular switch, he thought they were dead. Dozens of nematodes hung lifeless in solution, and Al-Atar could not see the rhythmic beating of their tiny pharyngeal bulbs (worm hearts) with his low magnification m

Experts in neurology, rehabilitation medicine, physical therapy, speech pathology, and anesthesiology gave the little girl an EEG, a test of her heart’s electrical activity

By Victoria Stern Dry out, put away The freezer meltdown was a huge disaster for Judy Muller-Cohn. One night in 1997, she lost millions of dollars’ worth of crucial DNA and protein samples. But this major meltdown at Mycogen Corporation, an agriculture and biotechnology company based in San Diego, ultimately had a happy ending for Muller-Cohn. “My husband and I knew that sample management was a major issue,” says Muller-Cohn. Her husba

But picture starting at a university that didn’t exist the year before, where the equipment you need to conduct your research is nonexistent, and you get an idea of what bioengineer Michelle Khine experienced in her first year at the University of Californi

It was September 2004, just a year after the group had made a joint decision to increase the moss field’s visibility. The moss field

By Fraser Black Time to Outsource Lab Management? Expert scientific asset management drives efficiency in R&D. The biotechnology and pharmaceutical industries waste huge amounts of time, money and resources, especially in operational areas. Pressure to improve cost effectiveness has spurred some innovation, including such approaches as process mapping and value analysis, also known as cost-out, in manufacturing. However, further opportunities exist to signifi

By Steven Wiley Why I Love Vendors Talks and posters are about where biology has been—but the booths with the sales pitches and freebies tell you where science is going. I have found that creating a new, useful tool for scientists can be just as gratifying as discovering a new protein. In December, I attended the annual meeting of the American Society for Cell Biology, as I have done regularly for the last several decades. It is always a good w

By Kai Simons My Life on a Raft The picture of the lipid bilayer of cell membranes as a boring solvent for proteins has given rise to one that is much more dynamic, and which is revealing new mechanisms and targets for drug delivery.

Illustrations by Tomasz Walenta nce in a generation, perhaps, a new research agency is born that does unprecedented things. The US National Science Foundation (NSF) got going (after 5 years of argument) in 1951 and its budget hit $1 billion 32 years later, in 1983. The budget of the UK Medical Research Council, which was

He was just trying to graduate. © Dan Porges Aaron Ciechanover could not have predicted that the humble system he was studying would play a central role in everything that happens from embryonic development to adulthood. Of course he was just a graduate student at the time. ̶

By Jeffrey M. Perkel Can Mass Spec Really Do That? Unexpected applications of a technique best known as a proteomics powerhouse. Mass spectrometry (MS) is not just about proteomics, though its star in that field certainly shines bright. As anyone in the drug discovery, food science, petroleum, or chemistry industries can tell you, mass spec is considerably broader than that. “Traditionally it was a technique for looking at relatively small compou

From the collection of Jack and Beverly Wilgus On September 13, 1848, a 25-year-old railroad worker named Phineas Gage triggered an explosion that propelled a 3 foot 7 inch iron rod straight through his skull, destroying a good portion of his brain. Luckily, the iron missed the critical blood vessels and parts of t
