Transcription — the transfer of DNA’s genetic information through the synthesis of complementary molecules of messenger RNA — forms the basis of all cellular activities. Yet little is known about the dynamics of the process — how efficient it is or how long it takes. Now, researchers at the Albert Einstein College of Medicine of Yeshiva University have measured the stages of transcription in real time. Their unexpected and surprising findings have fundamentally changed the way transcription is understood.
Cancer causing mutations occur in our bodies every day – but luckily, we have specific genes that recognize these malignant events and keep cells from growing out of control. Only a few of these genes – called tumor suppressors – are currently known.

A relatively new, minimally invasive treatment was 93 percent successful in eradicating malignant kidney tumors, according to a recent study conducted by researchers from Wake Forest University Baptist Medical Center in Winston-Salem, NC.
“I have performed many radiofrequency ablations of renal tumors and the results looked promising,” said Ronald J. Zagoria, MD, lead author of the study. “I wanted to scientifically review the data to better assess the results and look for patterns that might predict success or complications,” he said.
Finding an immune system in the social amoeba (Dictyostelium discoideum) is not only surprising but it also may prove a clue as to what is necessary for an organism to become multicellular, said the Baylor College of Medicine researcher who led the research that appears today in the journal Science.
One of the fundamental challenges facing organic synthesis in the 21st century is the need to significantly increase the efficiency with which carbon frameworks can be constructed and functionalized. Chemists at the University of Illinois are helping to meet this challenge by developing a class of carbon-hydrogen catalysts that are highly selective, reactive and tolerant of other functionality.M.
Researchers at Temple University have observed and documented electron transfer reactions on an electrode surface at the single molecule level for the first time, a discovery which could have future relevance to areas such as molecular electronics, electrochemistry, biology, catalysis, information storage, and solar energy conversion.
A new fingerprinting technique could potentially detect the diet, race and sex of a suspected criminal, according to new research published in the August edition of the journal Analytical Chemistry.
The team, led by Professor Sergei Kazarian from Imperial College London’s Department of Chemical Engineering, has devised a technique which collects fingerprints along with their chemical residue and keeps them intact for future reference.
The effect of logging on canopy nectar production in tall forest trees has for the first time been investigated by NSW DPI researchers, with funding from the Honeybee Program of the Rural Industries Research and Development Corporation and Forests NSW.
State forests provide the major honey resource for the beekeeping industry in NSW.
While Forests NSW has a number of management practices in place to retain nectar-producing trees during logging operations, there has been no information on how much nectar is produced by retained trees or young trees regrowing after logging.
A special type of cell found in the eye has been found to be very important in regenerating the retina in zebrafish and restoring vision even after extensive damage. Now, a UK team of scientists believe they may be able to use these cells – known as Müller glial cells – to regenerate damaged retina in humans, according to a study published this month in the journal Stem Cells.
