50-year-old Mystery Solved: Protein Tags Regulate Key Ion Channel
Researchers at the University of Chicago have found that a recently discovered biological process known as sumoylation -- until now thought to be active only in the nucleus -- also occurs near the cell's surface where it regulates at least one and possibly many kinds of proteins, providing a novel target for the development of new drugs. The discovery, published in the 8 April 2005 issue o...Mystery solved: Gold's power against autoimmune diseases defined
Gold compounds have been used for the treatment of rheumatoid arthritis and other autoimmune diseases for more than 75 years, but until now, how the metals work has been a mystery. Harvard Medical School researchers report in the Feb. 27 issue of Nature Chemical Biology that special forms of gold, platinum, and other classes of medicinal metals work by stripping bacteria and virus particles from...One big biology question solved
An Australian research team has solved one of biology's most fundamental questions ?why males produce sperm and females produce eggs. The finding is a breakthrough that could lead to improved infertility treatment, cancer therapy and pest management. The team, led by Dr Josephine Bowles and Professor Peter Koopman from the Institute for Molecular Bioscience at The University of Queensla...Solved: The mystery of flesh-eating bacteria's relentless attack
A Howard Hughes Medical Institute (HHMI) international research scholar in Israel has discovered one reason why so-called "flesh-eating" bacteria are so hard to stop. Emanuel Hanski, a microbiologist at Hebrew University in Jerusalem, and colleagues have found that the success of Group A Streptococcus is due in part to a protein that blocks the immune system's distress calls. The finding...Two central mysteries in genome inheritance solved at UCSD
The dance of the chromosomes during cell division, first described in the late 1800s and familiar to all high-school students from movies shown in biology classes, has long fascinated biologists. However, the molecular nature of a key component of cell division, the "chromosome-spindle" connection, which is critical for the inheritance of genetic information as cells divide, has remained elusive...Terri Schiavo is no more, but the question of Mercy killing is unresolved…
Terri Schiavo died in the Pinellas Park hospital on Thursday. Terri Schiavo, the severely brain damaged Florida woman, who was facing the right-to-die controversy.// She died today 13 days after her feeding tube was removed on the order of a state court judge. Terri Schiavo was 26 years when she collapsed in her home in 1990. She was suffering from potassium deficiency, due to extreme...Cholesterol Mystery Solved By Nobel Laureates
A 72 year old mystery about cholesterol synthesis which has been bugging scientists for so long has finally been cracked by Nobel laureates. // The Shoenheimer effect has long been unexplained, but not now. The first evidence for end-product feedback regulation of a biosynthetic pathway was demonstrated when Rudolph Shoenheimer observed that mice synthesized large amounts of cholestero...Mystery Surrounding Use Of Abortion Pill Yet To Be Resolved
Reports of the death of four Californian women due to the toxic shock syndrome following consumption of the abortion pill RU-486 (Mifeprex) has created much confusion // and controversy among members of the scientific community. It has been confirmed by health officials that it is due to the toxins produced by the highly lethal bacteria - Clostridium sordellii. So far, there have been o...Mystery Of The Placebo Effect, Yet To Be Solved
Placebo is usually given to patients who psychologically feel that they are unwell but are actually hale and healthy// . Some people are always under the notion that they are unwell and ask medicines to be prescribed by their General Practioners. But too much of medicines also lead to various problems in our body. Hence doctors prescribe placebo instead of medicines. Patie...Dry Earwax Mystery Solved: Ear Wax Gene Identified
An exhaustive genetic study conducted on more than 3000 people has helped solve one of the ancient mysteries associated with earwax. // It could eventually explain why some people have dry earwax while some others have a sticky, brown exudate. The study has further established that people from either a European or African descent tend to have sticky and wet earwax while those with an...
