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…

Ocean Floor Warming Affects Antarctic Seabed Life

By Neha Jain @lifesciexplore A rise in ocean temperatures by 1°C may not seem like a lot. But researchers were surprised to find nearly doubled growth of some species with just one-degree rise in ocean warming and varied growth responses of assemblages with two degrees of warming, in the most realistic marine warming study conducted in Antarctica to date. These drastic changes in community structure may have huge consequences for the entire ecosystem, as they affect the food chain. “I was not expecting such a visible difference,” said Gail Ashton,…

Vampires, or People with Blood Disorder?

By Michelle Dookwah @mtdookwah Vampires, or People with This Blood Disorder? Autumn is here, and with it comes cooler temperatures, shorter days, and a favorite fall holiday: Halloween. These last two features of the season have more in common than you may have realized. The shorter days of fall mean less daylight in the evening hours, and this might have a significant impact on the day-to-day lives of certain individuals with a particular blood disorder called erythropoietic protoporphyria. Erythropoietic protoporphyria (EPP) is a rare genetic disorder that results in hypersensitivity…

Ongoing Human Evolution Revealed in Data

By Kate Stone @GotScienceOrg When I was about nine years old, a young schoolmate demanded to know, “If evolution is real, then why isn’t it happening now?” Being nine and not a biologist, I wasn’t prepared to answer this question. And yet, it was a question that I’ve heard echoes of in the years to follow. Now, a research team at Columbia University has conducted a large-scale study of genetic data and revealed how humans are evolving. In a study analyzing the genomes of 210,000 people in the United States…

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…

Coral Gardening Effectively Restores Staghorn Corals

By Neha Jain @lifesciexplore Staghorn corals (Acropora cervicornis)—a threatened species that resembles deer antlers—are effectively restored by coral gardening, a process that involves cutting coral fragments from healthy, wild donor colonies, rearing the coral fragments in underwater nurseries, and outplanting or reattaching onto degraded reefs, finds a study conducted in the Caribbean. The study demonstrates that current restoration methods are very effective, that no excess damage is done to donor colonies, and that once outplanted, the corals behave like wild colonies. Stephanie Schopmeyer, a coral biologist at the University of…

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…

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…

Urban Life of Bees: A Pollination-Parasite Trade-Off

By Jonathan Trinastic @jptrinastic   Few people would consider cities the ideal home for bees, but what if these dense population centers could provide the means for healthy cohabitation? Scientists from Europe recently examined how bumblebees visit and pollinate flowers across urban and agricultural regions and found that urban areas can have a surprisingly beneficial effect on pollination rates. The reasons behind these results not only provide insight into how cities could be designed to better care for bees but also signal yet another danger of farming monocultures. Urban sanctuary…

Shelf Life Video: Screening Biodiversity

Scientists at The American Museum of Natural History explain why managing biodiversity is a key component in managing endangered species. This video is another in the Shelf Life series from the American Museum of Natural History. Even though one and a half million species of organisms have already been named and described, they represent just a tiny portion of the biodiversity of our planet. Having a distinct genetic identity is important because more variation tends to be better in the face of the changing world. And when populations get small and isolated…
