Scientists capture first optical images of carbon nanotubes inside a living organism

Using fruit flies, the researchers confirmed that a technique developed at Rice -- near-infrared fluorescent imaging -- was capable of detecting DNA-sized nanotubes inside living fruit flies.

The cell size problem

For more than 100 years, scientists have tried to figure out the cell size problem: How does a cell know when it is big enough to divide?

Researchers pinpoint when a cell is ready to reproduce

For more than 100 years, scientists have tried to figure out the cell size problem: How does a cell know when it is big enough to divide, In research conducted in budding yeast ( Saccharomyces cerevisiae ), scientists at Rockefeller University have now identified the cellular event that marks the moment when a cell knows it is big enough to commit to cell division and spawn genetic replicas of itself.

Two genes in mammalian cells act as gatekeepers for cellular longevity

In everything from yeast to primates, a significant decrease in calories can extend lifespan by as much as one-third. But getting under the hood of the molecular machinery that drives this longevity has remained elusive.

Everything that itches isn't a yeast infection!

Most women who think they have a vaginal yeast infection are wrong and may be doing more harm than good in treating their problem, says a Saint Louis University researcher who presented her findings recently.

Fruit flies have a taste for carbonated water

That fruit fly hovering over your kitchen counter may be attracted to more than the bananas that are going brown; it may also want a sip of your carbonated water.

Gene regulation in humans is closer than expected to simple organisms

Gene networks are some of the most basic features of a living organism. An external or internal stimulus activates some genes, which in turn control others genes whose activity turns on or off various biological processes (such as the cell cycle, energy production, DNA repair, cellular suicide etc).

First large-scale study of proteins inside human cells called Jurkat T cells

The study, which appears in the August issue of Molecular & Cellular Proteomics, could lead to a better understanding of how proteins inside a specific type of cell work together and may pave the way for future detailed studies of how proteins work in other types of cells.

All eukaryotic kinases share 1 common set of substrates

Kinase mediated phosphorylation is generally recognised as the major regulator of virtually all metabolic activities in eukaryotic cells including proliferation, gene expression, motility, vesicular transport and programmed cell death.

Antitumour drugs impede DNA uncoiling by topoisomerase I

The annoying bulges of an overwound telephone cord that shorten its reach and limit a caller's motion help explain why drugs called camptothecins are so effective in killing cancer cells, according to investigators led by Mary-Ann Bjornsti, Ph.D., at St. Jude Children’s Research Hospital, and Nynke Dekker, Ph.D., at Delft Technology University.

Chromatin remodeling complex connected to DNA damage control

When molecular disaster strikes, causing structural damage to DNA, players in two important pathways talk to each other to help contain the wreckage, scientists at The University of Texas M. D. Anderson Cancer Center report in the August edition of Cell.

Gene regulation drives evolution

It is not just what's in your genes, it's how you turn them on that accounts for the difference between species , at least in yeast , according to a report by Yale researchers in this week's issue of Science.

Promising new line in anti-cancer therapy

A promising new line in anti-cancer therapy by blocking the molecular motors involved in copying genetic information during cell division is being pursued by young Dutch researcher Dr. Nynke Dekker in one of this year's EURYI award winning projects sponsored by the European Science Foundation (ESF) and the European Heads of Research Councils (EuroHORCS).
