Type II diabetes is a rising global epidemic without any current treatments. But scientists have designed an interesting chimeric protein that aims to increase insulin sensitivity in patients and thereby provide a potential cure. Continue reading Using Chimeric Proteins to Fight Type II Diabetes
by Molly Sargen figures by Daniel Utter Water makes up 60-75% of human body weight. A loss of just 4% of total body water leads to dehydration, and a loss of 15% can be fatal. Likewise, a person could survive a month without food but wouldn’t survive 3 days without water. This crucial dependence on water broadly governs all life forms. Clearly water is vital … Continue reading Biological Roles of Water: Why is water necessary for life?
CRISPR genome editing has been used to study the biology of a number of species, but its use in reptiles has been difficult to achieve. Scientists have now figured this out, and albino lizards are the product! Read Ben Andreone’s article to learn more! Continue reading Albino Lizards are the First Ever Genome Edited Reptiles
Scientists are using carbon nanotubes to help damaged heart tissue, scarred from heart attacks, to function healthily again. Continue reading Carbon Nanotubes Restore Electrical Signals to Damaged Hearts
To achieve seamless cell-electronics interfacing, researchers have developed cyborg organs by growing human heart tissue together with dispersed, flexible electronics. Read Anqi Zhang’s article to learn more about cyborg organs! Continue reading “Cyborg” Human Organ Grown in a Dish
How prey species avoid multiple predators in the wild has long been puzzling, but now scientists have used GPS data from wolves, cougars, and elk at Yellowstone National Park to help unravel this mystery. Read Ben Andreone’s article to learn more! Continue reading Elk at Yellowstone National Park Outwit Multiple Predators to Stay Alive
Using fossil fuels has led to climate change; however, trees can erase some damage. By maximizing forest coverage on Earth, scientists predict that the carbon dioxide levels in the atmosphere could be reduced by a quarter—back to levels from a hundred years ago.

Researchers from MIT have developed a novel method to locally deliver drugs and prevent immune activity around implanted biomedical devices over several months. The method is based on the formation of crystals of immunosuppressive drugs, which can be included in devices and slowly dissolve over the course of months. While this method substantially increases the length of time tested devices can function, difficulty of crystallizing certain drugs or introducing them into specific devices may prove to be a challenge in adapting this method to other systems. Even so, for many cases, this method will likely substantially reduce the difficulty of maintaining device stability for extended periods of time. Continue reading Slow and Steady Drug Delivery Keeps Biomedical Devices Kicking
Bacteria in the human gut can modify the ingested drugs rendering them useless. Scientists discovered how the gut bacteria degrade a Parkinson’s disease medicine and found a way to stop them from stealing our drugs. Continue reading Hey, those bacteria are stealing our drugs!
