Greenhouse gases, such as carbon dioxide (CO2) and methane, contribute to global warming by slowing the rate at which heat energy escapes into space. Although methane is less abundant than CO2, it is several times more potent, absorbing up to 36 times…

Scientists generally agree that today’s birds descend from ancient flying dinosaurs, but nobody is sure exactly how the first flying dinosaurs actually took flight. A group of researchers from Tsinghua University and the Chinese Academy of Sciences…

by Catherine Weiner figures by Elayne Fivenson Every cell in our bodies is constantly on the edge of danger. Our DNA, the molecular blueprints that tell our cells how to function, brought us to life. But it is also just one error away from catastrophe.…

Heart attack is a leading cause of death, and often results in damage by overstretching the heart muscle. Once overstretched, the weakened heart muscle is less efficient at pumping blood, and it’s hard for the muscle to recover once the damage is formed…

Researchers at McMaster University have developed a novel method for stabilizing vaccines, removing the strict requirement that the components be maintained within a specific low temperature range from development through delivery. The technique is based…

Tyrannosaurus Rex, Triceratops, Saber-toothed Tiger…as kids, we probably imagined these creatures using a variety of crayon colors. But what if we could figure out what color these creatures actually were? A scientific technique developed by Roy Wogelius…

by Christopher Gerry Our DNA influences our height, eye color, affinity for sky diving and other extreme thrills, sleep habits, disease risk factors, and more. It’s no surprise, then, that scientists have found another job for our reliable genetic…

by Ankur Podder and Rhea Grover figures by Jovana Andrejevic Electric Vehicles (EVs) were once regarded as hopeless, tasteless, and incapable of replacing the fossil fuel-powered vehicles. In 2006, the award-winning documentary “Who Killed the Electric…

Electricity is created by electrons flowing through materials. Materials that allow electrons to travel through, like copper wires, are called conductors, whereas materials that inhibit electron flow, like rubber, are called insulators. However, the…
