Researchers create a melanin particle containing selenium, providing even more protection from harsh UV rays. These nanoparticles can be incorporated into clothing – providing astronauts a very lightweight alternative to lead shielding. Continue reading Artificial Sunscreen Protects Cells from X-ray Radiation
What makes all the different cheeses taste so wonderful? All of the different microbes that help make your cheese! Scientists have begun linking specific flavors to specific bacteria – meaning sometime soon we can start making designer cheese flavors. Continue reading How to improve cheese quality and taste? Understand the cheese’s microbial community.
Interviewee: Dr. Marc Schmidt, Professor of Biology, University of Pennsylvania Interviewer: Hope Merens, PhD Student in the Biological Sciences, Harvard University Pint-Sized Science · Pint-Sized Science: How do songbirds learn their songs? Have you ever wondered how a songbird knows the song that it sings? How successful are different songs at attracting female songbirds, and how do females decide what songs they like? What are … Continue reading Pint-Sized Science: How do songbirds learn their songs?
Researchers implemented an artificial pheromone system to allow robots to communicate within a swarm. Continue reading Robot Swarms Communicate with Artificial Pheromones
Don’t want to be bitten by mosquitoes? Well, new research has found a gene that can make females, the ones that bite, into males, the ones that don’t. Continue reading Want to control a pesky mosquito population? Convert all the females to males!
by Rebecca Silbermanfigures by Aparna Nathan It only took a few weeks of the coronavirus pandemic to send the American farm industry reeling. The supply chains that connect soy fields and chicken coops and greenhouses with American tables were not built for a world that lacks steady restaurant traffic or school lunches, where instead consumers are emptying supermarket shelves. There is at once a surplus … Continue reading Solace and Warnings From Our Planet’s Most Successful Non-Human Farmers
A recent study of tiger sharks reveals migratory changes based on life stage, sex, and season – and points to oil drilling platforms as key hangout spots, which could have large consequences for their population. Continue reading The Shark Movement: Fresh insight into Tiger Sharks in Gulf of Mexico
As the Roman Republic began to fall, the Earth suffered from extreme cold and famine that helped push Rome’s instability to its ultimate collapse. The cause of the extreme climate? The eruption of an Alaskan volcano on the opposite side of the world. Continue reading Et tu, Okmok? Alaska’s Okmok Volcano Contributed to Fall of Roman Republic and the Ptolemaic Kingdom
by Isabella Grabskifigures by Jovana Andrejevic In 1935, a scientist named Clive McCay published a startling discovery: rats with severely restricted diets lived up to 33% longer than previously known possible. Over the last few decades, similar experiments have been carried out on countless species, from worms to rodents and even primates. The specifics vary from study to study, but many show results just as … Continue reading Can Calorie Restriction Extend Your Lifespan?
Materials engineers at MIT have developed a new, more reliable design for a “memristor,” a component of computer circuits that could revolutionize artificial intelligence, improve efficiency of learning, lower energy costs, and fundamentally change the design of computers.
