Vadasaurus Fossil Shows a Reptile in Transition

By Kate Stone @GotScienceOrg A small fossil—just a foot long—is revealing secrets of how some land-dwelling reptiles moved back into the water. After studying the 155-million-year-old reptile fossil, scientists at Johns Hopkins University and the American Museum of Natural History report they have filled in some important clues to the evolution of animals that once roamed land and transitioned to life in the water. Vadasaurus, the Latin term for “wading lizard,” was discovered in limestone quarries near Solnhofen, Germany. The area was once part of a shallow sea that has…

How Can Caribbean Corals Cope with Climate Change?

By Justin Baumann @jbaumann3  The planet is warming. This is a fact we should all be comfortable with by now. As a result of this warming (and other human-caused stressors such as overfishing and nutrient pollution coupled with disease), coral reefs are in decline globally. Corals are animals that live in a symbiotic relationship with algae from the genus Symbiodinium. These symbionts are photosynthetic and transfer sugars to the coral host. While corals can also capture prey using their stinging cells and tentacles, most reef-building corals rely heavily on the…

New Ways to Reduce Antibiotics in Food Animals by 2030

By Neha Jain @lifesciexplore In a new study, researchers in the United States and Europe propose three measures—capping antibiotic use in farm animals, imposing a fee for veterinary use of antibiotics, and limiting meat intake—that, together, can reduce the use of antibiotics in food animals by up to 80 percent by 2030. Antibiotic resistance results from antibiotics overuse Overuse of antibiotics, particularly in animals for food, is the main cause of the spread of resistance whereby antibiotics lose their effectiveness, and infections become untreatable, leading to what many scientists call…

Shelf Life Video: The Salamander-Algae Symbiotic Relationship

What happens inside a Salamander egg? How does the embryo interact with its environment? Find out in this video, which is another in the Shelf Life series from the American Museum of Natural History.   Scientists collect Salamander egg masses to investigate the symbiotic relationship between embryos and algae. The two organisms exchange substances that help each other to thrive in their environment. Researchers are increasingly interested in how the microorganisms that are inside and on our bodies interact with us throughout the course of our lives and affect our physiology. GotScience…

Shelf Life Video: The Dinosaurs of Ghost Ranch

Dinosaurs’ fossils have attracted paleontologists to the Badlands of Ghost Ranch, NM, since 1881. Here, they have found the best place to find early carnivorous dinosaurs in the world. This video is another in the Shelf Life series from the American Museum of Natural History.   After being unearthed, dinosaurs’ bones are very delicate, and paleontologists need to take really good care of them. Once they are safely brought to the Museum of Natural History, they are ready to be analyzed. By looking at dinosaurs’ fossils, researchers can figure out…

Underwater Gardening: Coral Reefs and Aquaculture

By Shayna Keyles Twitter @shaynakeyles Instagram @shaynakeyles Our oceans are home to most of the world’s biodiversity, and 25 percent of its diversity thrives in coral reefs—that’s about two million species that call the reefs their home. But as reefs suffer the effects of climate change and globalization (several Caribbean reef-building species are now considered endangered), their ecosystems suffer, too. Fish colonies that provide food for coastal communities dry up, and the natural barriers that the reefs create become less effective, leading to more destruction in the wake of tropical…

Shortfin Mako Shark under Threat

By Kate Stone The shortfin mako shark is the fastest shark in the world. Its top cruising speed has been recorded at 40 kilometers per hour (kph), or 25 mph, with bursts of up to 74 kph, or 46 mph. Because shortfin makos are so fast, collecting accurate data about them has been especially difficult. Fortunately, new real-time satellite tracking technology has enabled researchers to gather much more accurate information about these amazing sharks. Unfortunately, the data is shockingly grim: shortfin mako sharks are being killed in fisheries at a…

Do Wandering Bees Help Spread Disease?

By Emily Rhode @riseandsci Given the continued growth of the human population, it’s no surprise that our behaviors impact plants and animals. But what might be alarming are the ways we harm these species. Habitat loss and pesticide use have been shown to have devastating effects on pollinator populations worldwide, but researchers from the University of Toronto have found a new and unexpected way that humans are killing off bumblebees. And according to their study, the potential for bee deaths will only get worse as our demand for pollinated crops…

Bee-coming a Beekeeper: An Interview with Andy Zaayenga

By Cathy Seiler @cyc55 Andy Zaayenga was “that guy” who introduced himself to new girlfriends by warning them about the 11-foot boa constrictor he kept as a pet. Not being okay with Andy’s love of all types of animals was a relationship dealbreaker. But despite Andy’s affinity to creatures big (especially in the case of the boa constrictor) and small, Andy’s career took him away from the animals and towards the inanimate. He’s spent most of his career repairing, selling, and developing automated solutions (a.k.a. robots) that doctors use to…

Chemicals Used on Almond Trees Linked to Bee Deaths

By Emily Rhode @riseandsci Americans have a serious obsession with almonds. In 2016, 1.2 million metric tons were grown worldwide, and 80% of that was grown in California alone. As our taste grows for the protein-packed nut, a looming crisis threatens not only the almond crop, but the global food industry as a whole. Over the last decade, honeybee populations, which are necessary for sustaining a healthy almond industry, have been steadily declining. The reasons for the decrease are not fully clear. What if our rabid consumption of this tasty…
