Recent findings by medical researchers indicate that naturally occurring nanotubes may serve as tunnels that protect retroviruses and bacteria in transit from…
Mice deficient in the fragile X mental retardation 1 gene (FMR1) and a similar gene called fragile X-related gene 2 (FXR2) have no rhythm to their wake and…
The largest ever study of bird genetics has not only shaken up but completely redrawn the avian evolutionary tree. The study challenges current…
Scientists at the Burnham Institute for Medical Research have, for the first time, genetically programmed embryonic stem (ES) cells to become nerve cells when…
The gene products, known as tRNAs, assemble amino acids for the production of proteins within mitochondria. If the mitochondrial tRNA genes are defective or…
However, Weibel's efforts to uncover the molecular choreography within the cell that governs their physical, chemical and physiological attributes – including…
It has long been known that the first backboned land animals or “tetrapods” – the ancestors of amphibians, reptiles, birds and mammals, including ourselves -…
AA amyloidosis is a potential complication of chronic inflammation or infection, for example, rheumatoid arthritis and tuberculosis, and is characterised by…
Researchers at Johns Hopkins have found that epigenetic marks on DNA-chemical marks other than the DNA sequence-do indeed change over a person's lifetime, and…
Reporting online Tuesday, June 24, 2008 in the Journal of the National Cancer Institute, Scott Waldman, M.D., Ph.D., professor and chair of Pharmacology and…
Rutgers researcher Karl Herrup and colleagues at Case Western Reserve University have discovered that a protein that suppresses cell division in brain cells…
The new “lab-on-a-chip” can automatically position, image, determine the phenotype of and sort small animals, such as the worm Caenorhabditis elegans that is…
The method, detailed in the current issue of Nature Nanotechnology, uses scanning near-field ultrasonic holography to clearly see nanoparticles residing within…
More than 15 years ago scientists discovered a way to stop a particular gene in its tracks. The Nobel Prize-winning finding holds tantalizing promise for…
Bloodsucking pests like bat fleas and bat flies may not sound very appealing to the rest of us, but to University at Buffalo biologist Katharina Dittmar de la…
Exploiting liver cells’ appetite for polystyrene ring “doughnuts”, just a few microns across, might give scientists a new way to deliver drugs selectively,…
