Buried beneath a sulfurous cauldron in European seas lies a class of microorganisms known as “extremophiles,” so named because of the extreme environmental conditions in which they live and thrive. Almost as radical, perhaps, is the idea that these organisms and their associated enzymes could somehow unlock the key to a new transportation economy based on a renewable biofuel, lignocellulosic ethanol.They're called extremophiles for a reason.
Seen thundering across the landscape during an aerial survey, more than 1.3 million white-eared kob, tiang (African antelope), and mongalla gazelle are thriving in Southern Sudan, despite all odds. An estimated 8,000 elephants, concentrated mainly in the Sudd, the largest freshwater wetland in Africa, have also been observed.
A large study has found that black Medicare patients are less likely than white patients to receive blood vessel opening procedures such as angioplasty following a heart attack, whether they are admitted to hospitals that provide or do not provide these procedures, but also experience higher mortality rates at 1 year, according to a study in the June 13 issue of JAMA.
A University of Warwick physicist has uncovered how female cells are able to choose randomly between their two X chromosomes and why that choice is always lucky.
Human males have both a X and a Y chromosome but females have two X chromosomes. This means that in an early stage in the development of a woman’s fertilised egg the cells need to silence one of those two X chromosomes. This process is crucial to survival and problems with the process are related to serious genetic diseases.
A chemist at the Vienna University of Technology (TU Vienna) is looking for unusual structures in snake venom and plans to prove their medical effectiveness.
What in the 1950s led to the development of Captopril, a drug for the treatment of hypertension, is being continued in an interesting new chapter with the analysis of venom from South American pit vipers and tropical rattlesnakes.
When the activity of individual genes it is longer required, there are two main mechanisms responsible for the “switching off”, mainly DNA methylation and the Polycomb protein complex.
Sometimes, these mechanisms lose their efficiency and some of the genes that should be “switched off” remain active. This, in turn, could lead to uncontrolled cellular proliferation, and tumorigenesis. These mechanisms, present both in lower organisms as well as in mammals, have always been thought to be separated and independent.
The era in which standard serology tests divided populations into two basic blood groups, ABO and Rh, may soon be a thing of the past. Nearly a century after blood group analysis began, new technologies for genotyping of blood offer a far more accurate picture of blood groups, experts reported at the 12th Congress of the European Hematology Association.
Slicing certain pills in half could slice a hefty amount off of America’s prescription drug costs. While only some types of pills can be split safely, the practice could be used by millions of Americans – including many of those who take popular cholesterol-lowering drugs.
The same genetic defect that causes a rare respiratory disease may also lead to some types of congenital heart disease, according to a new study from the University of North Carolina at Chapel Hill School of Medicine.
Want to play the ultimate version of The X-Men's "Wolverine" this Halloween? You'll need self-healing skin after those claws come out. Researchers at the University of Illinois are here to help. They have invented the next generation of self-healing materials, which mimics human skin by healing itself time after time. The new materials rely upon embedded, three-dimensional microvascular networks that emulate biological circulatory systems.Now they just need to invent that Adamantium exo-skeleton.
