Human endurance is not limitless
Imagine you’re running a race. But this is no normal race—this is a 140-day trek from Huntington Beach, CA to Washington, D.C. Welcome to Race Across the USA, a seemingly-superhuman feat that provides the perfect laboratory to study human endurance. After all, extreme athletes push their bodies to the proverbial “limit”—but what, exactly, is this limit? That’s what a new study published in Science Advances … Continue reading Human endurance is not limitless
Can converting methane into CO2 help reduce climate change?
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 more energy than CO2 over a century. Last year marked the first time that global methane concentrations reached levels 2.5 times greater than … Continue reading Can converting methane into CO2 help reduce climate change?
How did dinosaurs learn to fly? Robots can help model the flapping wings.
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 think they might be able to piece together the origins of flight using a mix of fossils, mathematical models, robotic models, and modern ostriches. The scientists started their … Continue reading How did dinosaurs learn to fly? Robots can help model the flapping wings.
Mending a Broken Heart: A new post-heart attack adhesive patch speeds healing
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 because the heart is always beating. It can’t ever stop to heal. Researchers from Brown University and Fudan University have developed an … Continue reading Mending a Broken Heart: A new post-heart attack adhesive patch speeds healing
A Sweet Solution for Preserving Vaccines
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 on drying the vaccines using two FDA-approved sugars and was shown to be successful in preserving vaccine effectiveness at elevated temperatures for twelve weeks. While it must still be validated on other vaccines, this method could be a major step toward cheap, accessible immunization in developing areas. Continue reading A Sweet Solution for Preserving Vaccines
So what color was that dinosaur, actually?
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 involving the Interdisciplinary Centre for Ancient Life at the University of Manchester may paint the ancient world in its truest form. Paleontologists use information contained in fossils to try … Continue reading So what color was that dinosaur, actually?
Electric Forest
Semiconductors are materials that are used as switches in modern electronics. While the switches in your computer and smartphone are made of silicon, carbon-based organic semiconductors offer the potential for flexible, inexpensive electronics. Toward this goal, students in CHEM 100R have synthesized a novel organic semiconductor. For an organic semiconductor film to perform well, it must be processed so that is both crystalline and continuous. Students in CHEM 165 … Continue reading Electric Forest
Conductors vs. Insulators: A Quantum Perspective
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 models behind our understanding have been incomplete. To understand which materials permit electron movement, scientists have investigated the patterns of electron motion in materials. Electrons do not behave like macroscopic objects. … Continue reading Conductors vs. Insulators: A Quantum Perspective
Pokémon Light Up the Brain
Need another reminder of the lasting impact that the Pokémon anime franchise has had on those who grew up in the 1990s? Rewind to the summer of 2016, when it became nearly impossible to walk down the street without bumping into a millennial immersed in the wildly successful ‘Pokémon GO’ mobile app. As it turns out, it is not just a sense of nostalgia that … Continue reading Pokémon Light Up the Brain
Health Data Privacy: Updating HIPAA to match today’s technology challenges
by Jordan Harrod figures by Dan Utter In the modern era, maintaining the privacy of your personal information has become more challenging than ever. Cyberattacks and social media have resulted in the average person sharing more information than ever before, in ways that they may not be aware of. One area of data privacy that isn’t discussed often, however, is health data. In the past, … Continue reading Health Data Privacy: Updating HIPAA to match today’s technology challenges
