Discovery of pathway that controls cell size and division

Organisms precisely regulate cell size to ensure that daughter cells have sufficient cellular material to thrive or to create specific cell types: a tiny sperm versus a gargantuan egg for example.

Scientits devise dimmer swith to regulate gene expression in mammal cells

Three Boston University biomedical engineers have created a genetic dimmer switch that can be used to turn on, shut off, or partially activate a gene's function. Professor James Collins, Professor Charles Cantor and doctoral candidate Tara Deans invented the switch, which can be tuned to produce large or small quantities of protein, or none at all.

New findings on gene-transcription machinery

For some time, scientists have been tracking down the sequence of biochemical steps required to attract and assemble at the head end of a gene the molecular machinery needed to transcribe that gene to put to work the information it encodes.

New insight into cell division and chromosones

St. Jude investigators have used the lowly yeast to gain insights into how a dividing human cell ensures that an identical set of chromosomes gets passed on to each new daughter cell.

Rochester now offers gene test to detect Batten disease

Rochester has become one of only a handful of communities around the world to offer a genetic test to detect Batten disease, a deadly inherited disorder.

Vaginal health

Silence may impact women's health since few women or their doctors are comfortable talking about vaginal health openly.

Magnetic nano tweezers show how cancer drug works

The annoying bulges of an over-wound telephone cord that shorten its reach and limit a caller's motion help to explain why drugs called camptothecins are so effective in killing cancer cells, according to investigators at St. Jude Children's Research Hospital and Delft University of Technology.

New insights into prion propagation

Prions - infectious, oddly-folded proteins that are the main suspects in fatal neurodegenerative diseases such as Cruetzfeldt-Jakob and bovine spongiform encephalopathy, or "mad cow" - remain mostly a mystery to scientists.

Discovery of enzyme critical in DNA replication

In this week's issue of Science, researchers from the National Institute of Environmental Health Sciences (NIEHS) and Umea University in Sweden report an important discovery about a critical new role that an enzyme called DNA polymerase epsilon plays in replicating DNA in higher organisms such as yeast and perhaps even humans.

Discovery of new gene with links to childhood asthma

New treatments for childhood asthma could be in the pipeline following the discovery of a gene associated with the condition.

Key finding on ALS related protein

Chemists from UCLA and the University of Florence in Italy may have solved an important mystery about a protein that plays a key role in a particular form of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, a progressive, fatal neurodegenerative disorder that strikes without warning.

New understanding of cancer inhibitor topotecan

Researchers in Delft University of Technology's Kavli Institute of Nanoscience in The Netherlands have cast new light on the workings of the important cancer inhibitor topotecan.

Scientists identify gene responsible for one type of Charcot-Marie-Tooth disorder

Scientists have identified the gene responsible for one type of Charcot-Marie-Tooth disorder, a common inherited neurological disease, thanks to the chance appearance of a strain of impaired 'pale tremor' mice in a University of Michigan research laboratory.
