BOZEMAN, Mont. -- Montana State University researchers have discovered a rare oasis of life in the midst of hundreds of geothermal vents at the bottom of Yellowstone Lake.
A colony of moss, worms and various forms of shrimp flourishes in an area where the water is inky black, about 90 degrees Fahrenheit, and a cauldron of nutrients, gases and poisons, the researchers reported in the September issue of Geobiology.
Acute herpes zoster, or shingles, interferes with all health areas for people with the condition, including sleep, enjoyment of life and general activities, according to a study published in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj091711.pdf.
It is time to phase out the use of codeine as a pain reliever because of its significant risks and ineffectiveness as an analgesic, states an editorial in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj101411.pdf.
Post-doctoral researchers see their role as being vital in technology transfer where scientific findings become useful to the local economy, but most have little interest in running their own business once their research fellowship ends. That's the surprising finding of a study published in the International Journal of Knowledge-Based Development.
Tucked within its double-helix structure, DNA contains the chemical blueprint that guides all the processes that take place within the cell and are essential for life. Therefore, repairing damage and maintaining the integrity of its DNA is one of the cell's highest priorities.
Biodiversity decreases towards the poles almost everywhere in the world, except along the South American Pacific coast. Investigating fossil clams and snails Steffen Kiel and Sven Nielsen at the Christian-Albrechts-Universität zu Kiel (CAU) could show that this unusual pattern originated at the end of the last ice age, 20.000 to 100.000 years ago. The retreating glaciers created a mosaic landscape of countless islands, bays and fiords in which new species developed rapidly – geologically speaking. The ancestors of the species survived the ice age in the warmer Chilean north.
Having survived for more than 400 million years, the horseshoe crab is now under threat – primarily due to overharvest and habitat destruction. However, climatic changes mayalso play a role. Researchers from the University of Gothenburg reveal how sensitive horseshoe crab populations are to natural climate change in a study recently publishedin the scientific journal Molecular Ecology.
Malnutrition often goes hand in hand with COPD and is difficult to treat. In a recent study researchers at the University of Gothenburg, have come up with a new equation to calculate the energy requirement for underweight COPD patients. It is hoped that
this will lead to better treatment results and, ultimately, better quality of life for these patients.
Patients facing planned surgery answered 36 per cent more questions about the procedure correctly if they watched an interactive multimedia presentation (IMP) rather than just talking to medical staff, according to research in the October issue of the urology journal BJUI.
Researchers from the University of Melbourne, Australia, randomised 40 patients due to undergo radical prostatectomy into two groups. The first group went through the standard surgery consent process, where staff explained the procedure verbally, and the second group watched the IMP.
Tobias Brügmann and his colleagues from the University of Bonn's Institute of Physiology I used a so-called "channelrhodopsin" for their experiments, which is a type of light sensor. At the same time, it can act as an ion channel in the cell membrane. When stimulated with blue light, this channel opens, and positive ions flow into the cell. This causes a change in the cell membrane's pressure, which stimulates cardiac muscle cells to contract.
The enigmatic Möbius strip has long been an object of fascination, appearing in numerous works of art, most famously a woodcut by the Dutchman M.C. Escher, in which a tribe of ants traverses the form's single, never-ending surface.
Jerusalem, October 4, 2010 – Researchers at the Hebrew University of Jerusalem have discovered a group of substances in the body that play a key role in controlling bone density, and on this basis they have begun development of a drug for prevention and treatment of osteoporosis and other bone disorders.
Berkeley – Diagnostic X-rays may increase the risk of developing childhood leukemia, according to a new study by researchers at the University of California, Berkeley's School of Public Health.
