The shapes and internal structures of individual cells within some of the earliest multicellular animals have been revealed for the first time using technology normally associated with hospitals.
Paleontologists Whitey Hagadorn of Amherst College and Shuhai Xiao of Tulane University have revealed the internal structure of 600-million-year-old fossilized embryos using specialized microscopic three-dimensional x-ray computer tomography (microCT). Hagadorn will present preliminary findi
What constrained the evolution of life during the very hot early Earth? Was a simple drop in temperature largely responsible for the emergence of cyanobacteria, a large and varied group of bacteria with chlorophyll that carry out photosynthesis in the presence of light and air with concomitant production of oxygen? Was it a reduction in carbon-dioxide levels?

17th International Congress on Thrombosis, Bologna, 26 October 2002: Important results from the EXPRESS clinical trial for the oral direct thrombin inhibitor (Oral DTI), EXANTA™ (oral ximelagatran and its active form, melagatran) show its superior efficacy in reducing risk of major venous thromboembolism (VTE), compared with a routinely used prophylactic treatment, enoxaparin, in major orthopaedic surgery.
Results show a significant 63 per cent relative risk reduction (2.3% vs 6.3%) in major ve
Washington University chemist offers radical new strategy in fight against cancer
Today, even the best cancer treatments kill about as many healthy cells as they do cancer cells but John-Stephen A. Taylor, Ph.D., professor of chemistry at Washington University in St. Louis, has a plan to improve that ratio. Over the last several years, Taylor has begun to lay the conceptual and experimental groundwork for a radical new strategy for chemotherapy — one that turns existing drugs into me
Elderly people who eat fish or seafood at least once a week are at lower risk of developing dementia, including Alzheimer’s disease, finds a study in this week’s BMJ.
Using data from a large ageing study, a team of French researchers set out to test whether there was a relation between consumption of fish (rich in polyunsaturated fatty acids) or meat (rich in saturated fatty acids) and risk of dementia.
The study involved 1,674 people aged 68 and over without dementia and liv
Raul Hernandez was no stranger to sports activity, and was active in Little League by the time he was 10 years old. But one day while running a short race at school, Raul experienced an intense burning sensation in his feet that turned his world upside down. From that day forward, he would experience severe pain in his feet any time he engaged in physical activity or, strangely, when the weather was hot or it rained. The situation worsened when the pain spread to his hands. His doctors, however, were
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
A new paper unravels the mysteries of a bizarre physical state known as the pseudogap, which has close ties to the sought-after state called high-temperature superconductivity, in which electrical resistance…
