Why didn't Darwin discover Mendel's laws?
Mendel solved the logic of inheritance in his monastery garden with no more technology than Darwin had in his garden at Down House. view more (2009-02-27)
Canadian breast cancer guidelines do not meet their objective
The Canadian Practice Guidelines for the Care and Treatment of Breast Cancer, first published in 1998, were developed to reduce variation in the way that breast cancer was being treated. view more (2007-03-13)
Scientists show that mitochondrial DNA variants are linked to risk factors for type 2 diabetes
Today, researchers report for the first time that genetic variants in mitochondria-energy-producing structures harboring DNA that are inherited only from the mother-are directly linked to metabolic markers for type 2 diabetes. view more (2007-08-13)
Women at risk from vitamin A deficiency
Almost half of UK women could be suffering from a lack of vitamin A due to a previously undiscovered genetic variation, scientists at Newcastle University have found. view more (2009-11-18)
Barnacles go to great lengths to mate
Compelled to mate, yet firmly attached to the rock, barnacles have evolved the longest penis of any animal for their size - up to 8 times their body length - so they can find and fertilize distant neighbours. view more (2008-02-07)
Cutting-edge weapons result of prehistoric experimentation
In today's fast-paced, technologically advanced world, people often take the innovation of new technology for granted without giving much thought to the trial-and-error experimentation that makes technology useful in everyday life. When the "cutting-edge" technology of the bow and arrow was introduced to the world, it changed the way... view more... (2008-06-11)
Sulphur in just one hair could blow a terrorist's alibi
A group of researchers from the LGC Chemical Metrology Laboratory in the United Kingdom and the University of Oviedo, Spain, have come up with a method to detect how the proportions of isotopes in a chemical element (atoms with an equal number of protons and electrons but different numbers of neutrons) vary throughout the length of a single hair. view more (2009-05-28)
Genetics for personalized coronary heart disease treatment
Identifying a single, common variation in a person's genetic information improves prediction of his or her risk of a heart attack or other heart disease events and thus, choice of the best treatment accordingly, said researchers at Baylor College of Medicine in Houston. view more (2008-11-12)
Scientists use nanoparticle to discover disease-causing proteins
A complex molecule and snake venom may provide researchers with a more reliable method of diagnosing human diseases and developing new drugs. view more (2007-02-13)
Predators ignore peculiar prey
Rare traits persist in a population because predators detect common forms of prey more easily. view more (2009-05-13)
Bacterial spread all down to chance: some strains 'just the lucky ones'
Scientists have discovered that factors such as human immunity and drug resistance are less important to the success of bacterial spread than previously thought. view more (2005-02-03)
'Fingerprinting' method tracks mercury emissions from coal
University of Michigan researchers have developed a new tool that uses natural "fingerprints" in coal to track down sources of mercury polluting the environment. view more (2008-10-09)
Male praying mantids prefer not to be victims of sexual cannibalism
Female praying mantids are notorious for sexual cannibalism - that is, for eating their male partner during mating. view more (2006-07-27)
Cell division find prompts overhaul of immune response modelling
Research at the Walter and Eliza Hall Institute into the mechanics of how two types of white blood cells grow and die is fundamentally changing the development of computer models that are used to predict how immune system cells respond to a pathogenic threat. view more (2009-07-21)
Longevity gene also protects memory, cognitive function
A gene variation that helps people live into their 90s and beyond also protects their memories and ability to think and learn new information, according to a study published in the December 26, 2006, issue of Neurology, the scientific journal of the American Academy of Neurology. view more (2006-12-26)
Central Africa's tropical Congo Basin was arid, treeless in Late Jurassic
The Congo Basin - with its massive, lush tropical rain forest - was far different 150 million to 200 million years ago. At that time Africa and South America were part of the single continent Gondwana. view more (2009-11-11)
New collaboration on rice DNA variation study
Perlegen Sciences, Inc., and the International Rice Research Institute (IRRI) announced today that they will collaborate to identify DNA variation in fifteen rice strains. view more (2005-11-17)
Global structures of the DE3 tide
Researchers from LAGEO , the Institute of Atmospheric Physics, has shown that the DE3 tide can propagate up to above 110 km height and exhibits 2-year cycle oscillation. Among all the diurnal tides in the upper atmosphere, this tide is the most prominent component other than the migrating diurnal tide. view more (2008-12-30)
Extraterrestrial platinum was 'stirred' into the Earth
Report author CSIRO Minerals Down Under Flagship researcher Dr Stephen Barnes said the study group collected a large body of data on the platinum content of lava flows called komatiites, which host some of the world's major nickel deposits. view more (2009-07-31)
Chimpanzee study reveals genome variation hotspots
Researchers believe that dynamic regions of the human genome - "hotspots" in terms of duplications and deletions - are potentially involved in the rapid evolution of morphological and behavioral characteristics that are genetically determined. view more (2006-05-16)
