Angela Howard was concerned when her infant daughter stopped crying, despite repeated jabs with an IV needle.

Despite lack of life on Saturn's moon, astrobiologists could gain much from mission

When scientists make long-term research plans, they must try to anticipate how emerging technologies will influence their work in the coming years.

Microarrays are wonderful tools for seeing global patterns of gene expression under different conditions.

Few research tasks are as time-consuming and tedious as scouring the scientific literature. The searcher might need only one nugget of information, yet it can take hours or days to slog through hundreds of papers before that one fact is found. Now, a new open-source tool called Textpresso http://www.textpresso.org can find a single fact just by typing in a quick search entry.Paul Sternberg's lab at the California Institute of Technology designed Textpresso to organize papers on Caenorhabditis el

Roland Siezen and colleagues at the University of Nijmegen, the Netherlands, have created a software tool that's long overdue. Most researchers in the eukaryotic model organism community have genome browsers capable of integrating and overlaying various datasets to produce annotated chromosome maps. Microbiologists, though, have been largely out of luck.Now the playing field has been leveled a bit. Microbial Genome Viewer (MGV; http://cmbipc49.cmbi.kun.nl/genome) is a free, open-source program t

Courtesy of Filippo RusconiWhile a graduate student, Filippo Rusconi couldn't come up with the money to pay for a Microsoft developer's license to continue work on his mass spectrometry program. So instead he rewrote the whole program in GNU/Linux. It turned out to be the best thing that happened to him, he says. "It allowed me to make the program a thousand times more powerful."The program, now called GNU polyxmass http://www.polyxmass.org is a complete software suite for mass spectrometrists t

Courtesy of IBMA new effort to unify the naming conventions of biological data is now underway in labs and companies throughout the world. The Life Science Identifier (LSID) Resolution Protocol Project consists of two software programs and a set of naming standards http://www.ibm.com/developerworks/oss/lsid.The first program is a server application called LSID Authority, which allows database and Web-site managers to identify their data with LSID URNs (uniform resource names, similar to URLs).

For a 30-year-old experimental method, gel electrophoresis remains popular. Originally devised as a method to extract nucleic acids from solution, it has evolved into a method for the analysis of everything from protein expression to matching RNA expression to proteins. "When we opened this facility three years ago, some people told me that in three years you won't do gel electrophoresis any more, so why invest in the equipment?" says Thomas Franz, head of the proteomics core facility at the Eur

Adecade-long war over genetically modified mice still rages. In 1994, Klaus Rajewsky's laboratory at the University of Cologne in Germany created the first transgenic conditional knockout mouse.1 With this mouse, researchers could turn on a genetic mutation at a specific period of development in a specific type of cell. Rajewsky assumed that his mouse would soon be used in labs throughout the world. Simply pleased with his research success, he never considered applying for a patent on a mouse. "

For decades, the behavioral sciences have been at a dramatic disadvantage to the hard sciences. When a biologist hypothesizes that the addition of a particular ligand to a cell will cause a certain gene to turn on and thus produce a certain protein, all she has to do is to introduce the enzyme and then test for the protein. If it's there, she publishes a paper; if it's not, she quietly discards the work.The psychologist has a much steeper hill to climb. Let's say he's trying to prove his hypothe
