by Arianna Lord Earlier this year, the Columbus Zoo and Aquarium performed artificial insemination on two of their female polar bears in hopes that the procedure would produce cubs. Polar bears greatly rely on Arctic sea ice for hunting, traveling, mating, and resting. However, because of the continued shrinking of sea ice due to climate change, polar bears have been listed as a threatened species … Continue reading Assisted Reproductive Technologies for Biodiversity Conservation
by Sanjana Kulkarni SARS-CoV-2 may have spread to humans from an animal host, but it is not the only disease-causing agent (i.e. pathogen) to have done so. Lyme disease, Ebola virus, influenza, HIV, the plague, and rabies virus are just some examples of zoonotic diseases, meaning that they originated in animals and spread (i.e spilled over) to humans. Many human activities, such as deforestation and … Continue reading Biodiversity Loss Can Increase the Spread of Zoonotic Diseases

When we think of biodiversity management, or maintaining the species diversity in an area, it’s easy to draw parallels to conservation. However, conservation usually focuses on one or few species at a time. This means that it often doesn’t mesh well with biodiversity maintenance, which requires considering the balance of all species in a given habitat. By managing a system based on the needs of … Continue reading Managing biodiversity: Indigenous knowledge, elephants, and the repercussions of intervention
Over 250 million years ago, cataclysmic volcanic activity wiped out nearly all life on earth. 65 million years ago, a meteor impact in the Yucatán drove the dinosaurs to extinction. In the past 540 million years of earth’s history, paleontologists have identified five mass extinction events in which over 75% of Earth’s species have died during a relatively short period of time [1]. Unfortunately, it … Continue reading Biodiversity and human health
Researchers from Heidelberg University have developed a sustainable approach to high-resolution 3D printing by using microalgae as “biofactories” to produce environmentally friendly, biocompatible inks, offering an alternative to conventional petroleum derived inks. Continue reading Nature’s Ink: Microalgae Biofactories for Creating Sustainable 3D Printing Inks
by Sanjana Kulkarnifigures by Swathy Karamchedu Forensic DNA testing has become crucial in criminal investigations and legal proceedings. DNA has linked people to crime scenes using hair or blood and exonerated wrongfully convicted individuals. This type of DNA is called environmental DNA (eDNA) because it is collected from the environment, rather than from a person. Scientists have also begun analyzing eDNA from non-human organisms. All … Continue reading DNA Detectives: How scientists are using DNA from the environment to see the unseen
Rivers, skies, and mountains become legal persons under Rights of Nature laws, but their implementation has been difficult. To help interpret and enforce these laws, scientific knowledge must be integrated. Continue reading Can Science Boost the Rights of Nature Movement?
by Salvador Balkus Collectively, scientists conduct a lot of experiments. Whether they study addiction, air pollution, or animal populations, most basic scientific experiments have one thing in common: data. To perform an experiment, scientists first formulate a hypothesis about how something works. Then, they collect data – measurements, sensor information, images, surveys, and the like – that either support their hypothesis or prove it false. … Continue reading How do scientists know whether to trust their results?
by Isle Bastillefigures by Allie Elchert In an episode of the BBC show Planet Earth there is a harrowing scene depicting thousands of freshly hatched baby sea turtles scuttling away from the sea towards a busy highway. A somber voice-over relays that the hatchlings are misguided by the nearby city lights. Paradoxically, while this was a human-driven habitat disruption, the turtles will not survive without … Continue reading Can assisted colonization save endangered species?
