A Day in the Life of a Vascular Biologist

By Noeline Subramaniam (@spicy_scientist) A vascular biologist studies blood vessels. Blood vessels connect all of our organs and tissues in our body to each other; as such, they play a crucial role in helping to maintain homeostasis—in other words, keeping the balance within our body. They have several important functions including transporting nutrients and removing waste, sensing blood flow, playing a role in the immune system, and much more. The two major types of blood vessels are arteries and veins. Arteries travel away from the heart and veins return to the…

Science with Sophie: Scab Science

Scab Science It’s happened to all of us. You’re running or riding your bike, you slip, you fall, and you skin your knee. After a few days, you notice that the cut where you skinned your knee has formed a scab. What happens to our bodies when we get hurt? Why do we get cuts, and why do we get scabs afterward? Learn how white blood cells, proteins, and skin cells work together to help you get better after you get hurt in this episode of Science with Sophie! Do…

When Aquatic Invasive Species Take Over

By Natasha Parkinson @schrodicatsci The weather is hot, and everyone is trying to cool off any way they can. Everyone with a boat is out on the water, tubing, waterskiing, fishing, or cruising around. Anyone that has been around boats knows about boat safety: wear a life jacket, and don’t operate watercraft under the influence. But one aspect that is less discussed is preventing the spread of aquatic invasive species while you are on the water. Aquatic invasive species So what is an aquatic invasive species? Well, it is either a…

Fire Management in California's Chaparal: The U.S. Army Corps of Engineers Sacramento District conducted a controlled burn of central marine chaparral at Fort Ord, Calif., Oct. 15, to expose unexploded ordnance at the formerly utilized defense site. The burn, carefully coordinated with local agencies, lasted less than two hours and was timed so that prevailing winds would help blow the smoke away from population centers. The controlled burns are part of a comprehensive ordnance removal program at Fort Ord, which closed in 1994 under recommendation from the Base Realignment and Closure Commission.

Fire Management in California’s Chaparral Harms Birds

By Neha Jain @lifesciexplore California suffered its largest and most destructive wildfires in 2017. Victims included hundreds of wild animals. When the blazing fires were finally extinguished, the surviving animals—including birds—were forced to find new homes. Now, for the first time, researchers investigating the effect of fire management practices on birds in California’s chaparral have found that one practice known as mastication, which consists of mechanically crushing vegetation to remove fuel, threatens bird communities. “The best available science tells us that managing chaparral imperils wildlife and increases fire risk,” says…

Language Detectives

Where did the Uto-Aztecan language originate? An interdisciplinary research project looked at a set of 100 words to understand the sound sequences of this language. Watch this video to see how an anthropologist and a computational biologist carried out this research. This is another in the Shelf Life series from the American Museum of Natural History. Museum curators Peter Whiteley, an anthropologist, and Ward Wheeler, a computational biologist, joined forces to trace the evolution of Native American languages by applying gene-sequencing methods to historical linguistics. I became fascinated by the idea…

Citizen Science Promotes Environmental Engagement

By Neha Jain @lifesciexplore Citizen science projects are rapidly gaining popularity among the public, in which volunteers help gather data on species that can be used by scientists in research. And it’s not just adults who are involved in these projects—even kids have collected high-quality data in the US. In addition to producing more data for scientific research, citizen science promotes interest in conservation and public awareness. Now, an Australian study has found that first-year university students can benefit from increased environmental engagement and greater understanding of their studies when…

Fabulous Fat: Lipid-Based Nutrient Supplements Combat Malnutrition

By Shayna Keyles @shaynakeyles Malnutrition affects hundreds of millions of children around the world. As of 2017, about 23 percent of children under five suffer from stunted growth because of malnutrition and about 8 percent experience extreme wasting, which is characterized by a low weight-to-height ratio. Although over the years many treatments have been developed that reduce chances of mortality, increase weight gain, and improve lean tissue creation—all signs of healthy development—more work is necessary to create an inexpensive, accessible, and long-term solution. Médecins Sans Frontières (MSF; also known as…

The “Google Manifesto”: Bad Biology, Ignorance of Evolutionary Processes, and Privilege

By Agustin Fuentes, PhD, University of Notre Dame There are biological differences between the sexes, including average body size and upper body strength, and aspects of reproductive physiology. There is also a range of gendered differences in behavior and perception as contemporary societies structure developmental patterns and expectations differently for boys and girls. But there are more biological similarities than differences, and more gender overlaps than discontinuities, between males and females—we are the same species after all. These differences and similarities can, and do, play roles in shaping performance on specific tasks by individuals…

Spinach and Siderophores: The Bacterial Battle for Iron

By Ada Hagan @adahagan Many remember the boisterous, muscle-bound, tattooed sailor Popeye and the thin-as-a-rail Olive Oyl from Saturday morning cartoons. In times of need, such as when his rival Bluto abducted Olive Oyl for the 50th time, Popeye would squeeze open a tin can of spinach. Eating the spinach, sometimes miraculously through his corn-cob pipe, gave Popeye that extra boost of energy needed to escape his bonds and rescue Olive Oyl. What was so special about spinach that gave Popeye his superpower? Iron. Or so I thought. It’s popularly…
