New Theory Tests Sex Ratios Under Asymmetrical Local Mate Competition
In a new study featured in the September issue of The American Naturalist, David M. Shuker (University of Edinburgh) and colleagues show that females alter the sex ratio they produce on a host by considering whether there are already eggs on the host they are using and if there are other eggs already laid on other hosts in the patch. Targeted Drug Delivery Achieved With Nanoparticles
Ground-breaking results from researchers at Harvard Medical School and Massachusetts Institute of Technology (MIT), USA, disclosed at the 13th European Cancer Conference (ECCO) have shown for the first time that targeted drug delivery is possible using nanoparticle-apatamer conjugates. 'Hot'Ice Could Lead To Medical Device
Physicists have shown that specially treated diamond coatings can keep water frozen at body temperature, a finding that may have applications in future medical implants. Researchers spent a year building and examining computer models that showed that a layer of diamond coated with sodium atoms will keep water frozen up to 108 degrees Fahrenheit. In ice, water molecules are arranged in a rigid framework that gives the substance its hardness. The process of melting is somewhat like a building falling down: pieces that had been arranged into a rigid structure move and flow against one another, becoming liquid water. Genetically Engineered Rice Found In Two Rice Varieties, USDA Investig
Trace amounts of genetically engineered rice was present in two varieties of rice, Cheniere and CL131. No short- or medium-grain rice varieties tested positive for either GE strain investigated. The exact mechanism for introduction of the GE material could not be determined in either instance. Prenatal Cocaine Exposure Increases Heart Susceptibility To Ischemia,
Cocaine abuse is becoming increasingly prevalent among women of childbearing age, and is associated with numerous adverse perinatal outcomes. New research, published in The Journal of Physiology, by Professor Lubo Zhang and his research team from Loma Linda University School of Medicine in California presents the exciting novel finding that cocaine exposure in utero has lasting and lifelong adverse effects on the heart in adulthood, particularly if you are male! Unusual Material That Contracts When Heated Is Giving Up Its Secrets T
Most solids expand when heated, a familiar phenomenon with many practical implications. Among the rare exceptions to this rule, the compound zirconium tungstate stands out by virtue of the enormous temperature range over which it exhibits so-called "negative thermal expansion,"contracting as it heats up and expanding as it cools, and because it does so uniformly in all directions. See What You're Spewing As You Speed Along
In the future, drivers may only have to glance at the dashboard to see the pollution spewing out of their vehicle's exhausts. Scientists have constructed a laser measuring device capable of recording levels of carbon dioxide, carbon monoxide and methane from directly inside an exhaust. Science Geek Gifts for All
Banish underwear from your gift-giving list this year! Your smarty-pants friends and relatives aren't as hard to buy for as you might think. The web is full of brain-gratifying gift ideas. By Kristen Philipkoski. Iron Exporter Revealed That May Explain Common Human Disorder
The first direct evidence that a single protein is critical in the cellular export of iron may help to explain human hemochromatosis, researchers report in the March issue of Cell Metabolism. Everything I Need to Know About (Real) Robots I Learned From Transform
Transformers don’t care about people, period. That's what I learned growing up in the 1980s, religiously watching a race of robot Titans from outer space wage a secret war on Earth.
