Lost Colonies
Anna Azvolinsky | Oct 1, 2015 | 10+ min read
Next-generation sequencing has identified scores of new microorganisms, but getting even abundant bacterial species to grow in the lab has proven challenging.
Stem cells for brain cancer

FEATUREThe Ecology of Tumors Stem cells for brain cancer BY PETER B. DIRKSNeural stem cell biology took off in 1992 when Brent Reynolds and Samuel Weiss, working at the University of Calgary, discovered that culturing mammalian brain cells in serum-free conditions (in EGF and bFGF), yielded clonally derived colonies of undifferentiated neural cells (neurospheres). This culture system demonstrated that cells within these colonies showed cardinal pr
Surpassing the Law of Averages

By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo

Fungi Squeezed Through Microchannels Offer Clues to Cell Growth
Catherine Offord | Jun 1, 2021 | 3 min read
A study finds that fast-growing species are stymied by narrow gaps, while slower-growing species can pass through and continue extending.
Leukemia and Cancer Stem Cells

FEATUREThe Ecology of Tumors Leukemia and Cancer Stem Cells BY IRVING WEISSMAN AND MICHAEL CLARKECancers and normal tissue stem cells have much in common: Both have self-renewal capacity, and both develop into differentiated progeny. But do true cancer stem cells exist? We believe that they do and that this realization will have a major impact on the understanding and treatment of cancers. Putative cancer stem cells can be recognized by three attr
Woods Hole Lab Faces Uncertain Future
Elizabeth Pennisi | Aug 7, 1988 | 10 min read
Celebrating its centennial, the Marine Biological Laboratory adapts to a new era in which money talks as loudly as science WOODS HOLE, MASS.—When Harlyn 0. Halvorson, the new director of the Marine Biological Laboratory in Woods Hole, blows out the candles for his institution’s 100th birthday this summer, no one will have to ask what he wished for. The laboratory needs more money, more room, and more molecular biology if it is to remain in the forefront of scientific research durin
The Genetics of Society

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.
Skipping Pluripotency
Jef Akst | Sep 14, 2011 | 5 min read
Researchers are developing ways to convert mature somatic cells from one cell type to another, avoiding the tumor-causing pluripotent stage associated with stem cells.

What’s the Deal with Bacterial Nanotubes?
Sruthi S. Balakrishnan | Jun 1, 2021 | 10+ min read
Several labs have reported the formation of bacterial nanotubes under different, often contrasting conditions. What are these structures and why are they so hard to reproduce?
