A Theory Blossoms
Bob Grant | Nov 1, 2009 | 4 min read
By Bob Grant A Theory Blossoms Researchers unfold a key step in the process that tells plants to flower, findings that could one day benefit agriculture. Fluorescent FT protein in the phloem of an Arabidopsis plant. Courtesy of Laurent Corbesier and George Coupland Few acts of nature seem simpler than flowers blooming on the outstretched tips of a plant’s shoots. But the induction of that seemingly simple process baffled pla

Biofilms are home to millions of microbes, but disrupting their interactions could produce more effective antibiotics.
GPCRs: Researchers Disprove the Single Polypeptide Theory
Jim Kling | Oct 28, 2001 | 5 min read
For this article, Jim Kling interviewed Bryen A. Jordan, postdoctoral scientist in the lab of Edward Ziff at the New York University School of Medicine's department of biochemistry; Theresa Branchek, vice president of research at Synaptic Pharmaceutical Corp. (Paramus, NJ); and Christophe Gerald, vice president of target discovery and assessment at Synaptic Pharmaceutical. Data from the Web of Science (ISI, Philadelphia) show that Hot Papers are cited 50 to 100 times more often than the average
The Path Less Traveled
Bob Grant | Feb 1, 2010 | 4 min read
By Bob Grant The Path Less Traveled A freshly demonstrated theory on how peptides enter cells sparks ongoing debate. The uptake of fluorescein-labeled peptides into cells via endocytosis at 5 microM peptide (top) and independent of endocytosis at 20 microM peptide (bottom) Courtesy of Roland Brock Describing how peptides and proteins traverse cell membranes is huge in the field of cell biology. Peptides, short chains of amino acids,

(A-E) represent cells containing HAT-tagged proteins stained with the DNA dye, DAPI, and a monoclonal antibody against hemagluttinin, α-HA. At right the images are merged. (F-J) indicates cells carrying V5 tagged proteins. The bar equals 2 μm.Aliens sifting through the remains of a lost human civilization might puzzle over the function of a ladle. But if found in a room associate

Sidebar: Society for Neuroscience NEW MESSENGERS: Caltech’s Erin Schuman and colleagues discovered that one form of nitric oxide is important to long-term potentiation. Can you recall where you were when you heard about the explosion of the space shuttle Challenger? Why is it that, almost universally, people can remember with vivid and instantaneous detail this tragic event when they can't recall what they had for dinner just days before? How are some memories indelibly hard-wired into o

Leonard Hayflick has been unafraid to speak his mind, whether it is to upend a well-entrenched dogma or to challenge the federal government. At 86, he’s nowhere near retirement.
Exosomes Make Their Debut in Plant Research
Amanda Keener | Feb 1, 2019 | 10+ min read
A growing branch of research on how plants use exosomes to interact with their environment is opening up a new field of plant biology.
Image Is Everything

Date: February 1, 1999Table of Confocal Microscope Manufacturers Perhaps in few other fields has the creation of an instrument been so important to the establishment of a new theory or discipline. Even the Galilean telescope, with its revelation of the Medicean moons, does not compare to the microscope because the foundation for astronomy had already been well established by naked-eye observation. Cell theory, by contrast, had no such foundation in anecdotal experience. However, it wasn't long
