EMBL researchers discover a mechanism by which cells monitor estrogen
The hormone estrogen is recognized by most people because of its important role in women’s reproductive cycles. It also has other functions in the body: it drives some types of cells to replicate themselves, and it has been linked to the development of tumors. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg have now described a new model of how cells constantly monitor their exposur
The same characteristics that make misfolded proteins known as prions such a pernicious medical threat in neurodegenerative diseases may offer a construction toolkit for manufacturing nanoscale electrical circuits, researchers report this week in the online edition of the Proceedings of the National Academy of Sciences.
Scientists working at Whitehead Institute for Biomedical Research and the University of Chicago write that they have used the durable, self-assembling fibers formed by prions as
Vitamin C helped convert mouse embryonic stem cells growing in the laboratory to heart muscle cells, researchers report today’s rapid track publication of Circulation: Journal of the American Heart Association.
Rapid track articles are released online early because they have major clinical impact or represent important basic science discoveries. This basic-research discovery could lead to future research on ways to treat people suffering from damaged heart muscle.

A protein responsible for the assembly of cell cilia – the hair-like projections from cells – may cause polycystic kidney disease, the most common genetic cause of kidney failure, according to a new study at UT Southwestern Medical Center at Dallas.
The study, which will be published online this week and will appear in a future edition of the Proceedings of the National Academy of Sciences, is the first to directly test the role of cilia in polycystic kidney disease. Previous studies have h
Researchers from Chicago have identified focal neurological deficits as a major group of presenting symptoms among patients with West Nile Virus infection, which became epidemic in the United States in 2002. Focal neurological deficits included visual loss, muscle weakness, paralysis of one half of the body, abnormally slow movement, tremor with rigidity, numbness or tingling and unstable gait. Findings of their study are being presented at the American Academy of Neurology Annual Meeting in Honolul
Researchers have found disturbing new evidence suggesting that environmental exposure to a ubiquitous substance may cause chromosomally abnormal pregnancies. They have learned that low levels of a compound used in the manufacture of common plastic food and beverage containers and baby bottles interfere with cell division in the eggs of female mice. The disruption of cell division can result in an abnormal number of chromosomes in the eggs, a condition known as aneuploidy, which is the leading cause o
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
A new paper unravels the mysteries of a bizarre physical state known as the pseudogap, which has close ties to the sought-after state called high-temperature superconductivity, in which electrical resistance…
Researchers from Delft University of Technology in The Netherlands have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to…
