Comparing cell and test tube

04-Feb-2016

Researchers often analyse isolated biomolecules in test tubes, and it is doubtful if the results can be applied to densely-packed cells. A team from Bochum, Dortmund and Greifswald monitored the folding of an RNA structure in the living cell and compared the results with those of test tube ...

The Nobel Prize in Physiology or Medicine 2010 goes to Robert G. Edwards for the development of in vitro fertilization

04-Oct-2010

Robert Edwards is awarded the 2010 Nobel Prize for the development of human in vitro fertilization (IVF) therapy. His achievements have made it possible to treat infertility, a medical condition afflicting a large proportion of humanity including more than 10% of all couples worldwide. As early ...

A drug against AIDS could be effective against the herpes virus

Researchers at IRB Barcelona have discovered this with the human cytomegalovirus, the most deadly and widespread herpes virus and the cause of serious defects in neonates

27-Sep-2010

Scientists at the Institute for Research in Biomedicine (IRB Barcelona) headed by the coordinator of the Structural and Computational Biology Programme, Miquel Coll, have published a new study that demonstrates that raltegravir, the drug approved in 2007 for the treatment of AIDS that is sold by ...

One molecule, many more insulin-producing cells to treat diabetes, says Pitt team

30-Jul-2010

With a single stimulatory molecule, human insulin-producing beta cell replication can be sustained for at least four weeks in a mouse model of diabetes, according to researchers at the University of Pittsburgh School of Medicine in Diabetes, a journal of the American Diabetes Association. They ...

Same types of cell respond differently to stimulus, Stanford study shows

28-Jun-2010

Using new technology that allows scientists to monitor how individual cells react in the complex system of cell signaling, Stanford University researchers have uncovered a much larger spectrum of differences between each cell than ever seen before. Cells don't all act in a uniform fashion, as was ...

Acne drug prevents HIV breakout

23-Mar-2010

Johns Hopkins scientists have found that a safe and inexpensive antibiotic in use since the 1970s for treating acne effectively targets infected immune cells in which HIV, the virus that causes AIDS, lies dormant and prevents them from reactivating and replicating. The drug, minocycline, likely ...

Enzyme design with remote effects

Chemists in Mülheim devise a new way of optimising enzymes for industrial applications

17-Feb-2010

Engineers are unlikely to tinker with the cooling system if they want to increase the size of an engine. Yet chemists at the Max Planck Institute for Coal Research have adopted an approach similar to this in their efforts to optimise an enzyme for practical applications. They substituted two ...

Cells can read damaged DNA without missing a beat

12-Feb-2010

Scientists have shown that cells' DNA-reading machinery can skim through certain kinds of damaged DNA without skipping any letters in the genetic "text." The studies, performed in bacteria, suggest a new mechanism that can allow bacteria to develop resistance to antibiotics. The results were ...

Research sheds light on workings of anti-cancer drug

Crystal structure shows how drug disables harmful copper in cells

01-Dec-2009

The copper sequestering drug tetrathiomolybdate (TM) has been shown in studies to be effective in the treatment of Wilson disease, a disease caused by an overload of copper, and certain metastatic cancers. That much is known. Very little, however, is known about how the drug works at the ...
