Engineers have designed an armrest that reduces repetitive strain injuries and has the potential to be used in almost anything with a seat, from heavy machinery to powered wheelchairs. Tests show the provisionally patented armrest reduces muscle activity in the neck by more than 60 per cent compared to typical armrests, said the researcher. Genetic Changes Shown To Be Important Indicators For Disease Progressi
Cervical cancer patients with specific changes in the cancer genome have a three- or fourfold increased risk of relapse after standard treatment compared to patients without these changes, according to a new study. The research suggests that specific genetic changes are crucial steps in the progression of the disease towards an aggressive and treatment-resistant state. Mayo Clinic Reports Tamoxifen Benefit For Breast-cancer Patients Tied
One of the most commonly administered drugs for breast cancer, tamoxifen, may not be as effective for women who inherit a common genetic change, according to researchers at Mayo Clinic and the University of Michigan. New Finding Points Way To Foiling Anthrax's Tricks
Anthrax, when inhaled, is nearly always fatal, in part because the bacteria have a very effective way of stealing iron from human cells to reproduce. This involves two molecules, siderophores, that compete with the body's own iron-transport molecules. UC Berkeley researchers have now found that humans produce a protein that sidelines one of these siderophores, but not the other. A drug that blocks the second siderophore should be able to stop anthrax in its tracks. Transgenics Transformed: Maize Mini-chromosomes Can Add Stacks Of Func
A new method of constructing artificial plant chromosomes from small rings of naturally occurring plant DNA can be used to transport multiple genes at once into embryonic plants where they are expressed, duplicated as plant cells divide, and passed on to the next generation -- a long-term goal for those interested in improving agricultural productivity. The Best Both Of Worlds: How To Have Sex And Survive
Researchers have discovered that even the gruesome and brutal lifestyle of the Evarcha culicivora, a blood gorging jumping spider indigenous to East Africa, can't help but be tempted by that "big is beautiful"mantra no matter what the costs. Researchers found that despite the inherent risk of sexual cannibalism, virgin females were attracted to bigger males when losing their virginity before opting for the safer smaller male as a longer term mate choice. Critical Protein Prevents DNA Damage From Persisting Through Generatio
A protein called ATM, long known to be involved in protecting cells from genetic damage, is also part of a system that prevents damage from being passed on when the cells divide. Star-shaped Cells In Brain Help With Learning
Every movement and every thought requires the passing of specific information between networks of nerve cells. To improve a skill or to learn something new entails more efficient or a greater number of cell contacts. Scientists can now show that certain cells in the brain -- the astrocytes -- actively influence this information exchange. Automated Water Safety Sensor Units Detect Currently Unmonitored Biolo
Sandia National Laboratories, CH2M Hill, and Tenix Investments Pty. Ltd. today announced a multi-year, multi-million dollar partnership to develop an unattended water safety system that offers the unique capability of detecting currently unmonitored biological agents such as bacteria, viruses, and protozoa that could threaten water supplies.
