Depending on the heart rate your doctor measures during your annual checkup, you might get a stamp of approval — or a raised eyebrow and questions about your overall health.But a new study confirms that a normal resting heart rate isn't the same for everyone. Data from over 92,000 FitBit-wearers were analyzed in a new PLOS ONE paper, showing that average resting heart rates ranged between 40 and 109 beats per minute (BPM). Though not all of those rates are necessarily healthy, the study did fi ...read more
Apollo 7 sent a trio of astronauts into space in 1968, making it the first successful crewed NASA mission. But about 15 hours into the flight, astronaut Wally Schirra began developing the symptoms of a bad head cold, with the rest of his team following suit. Balancing a fog of symptoms, including sniffles and congestion, on top of their heavy workload was a recipe for misery. Considering the extensive training and screening astronauts go through to ensure they’re in optimal health for missions ...read more
As winter approaches, bears and other hibernators — from butterflies to box turtles — begin preparing to clock out until spring. Us humans, on the other hand, find ourselves stuck all-too-consciously contemplating the frozen months ahead. In winter, everything feels twice as hard: getting dressed, shoveling snow, averting existential meltdown. Wouldn’t it be nice to ring in the new year, promptly tunnel down some dark burrow, and curl up to wait for better days?There’s no clear path to h ...read more
Radio telescopes around the globe have provided scientists with data on astronomical phenomena for nearly a century. We have even built telescopes and sent them into orbit, the most recent of which — the James Webb Space Telescope (JWST) — has provided astronomers with brand new insights into the formation of early galaxies, nebula where stars are born, and the chemical composition of atmospheres of newly discovered worlds.But science doesn't stop. Astronomers have been asking what the next ...read more
The Science Near Me blog is a partnership between Discover magazine and ScienceNearMe.org.If you’re searching for a place to learn, create, and explore all kinds of STEM activities, look no further than a local science festival! These events happen all over the country and offer exciting opportunities to learn about and do science right.Some science festivals are localized enough to be hosted on a college campus, like the Virginia Tech Science Festival, while others span entire cities and stat ...read more
Before the Neolithic Revolution, around 12,000 years ago, Homo sapiens lived scattered about the world in small groups, mostly with their extended families. They hunted, gathered and moved around, living in temporary shelters.They had to follow the food because they didn’t yet know how to grow their own. But gradually, over generations, agriculture began sprouting up across the globe, and the world began to change. Early H. sapiens could finally stay in one place because they cultivated th ...read more
Because of adverse weather conditions and city lights, a major migration collision killed 960 birds after they crashed into the McCormick Place convention building in Chicago on Oct. 5, 2023, according to Cornell Lab experts on BirdCast.“Prior to this, the highest number [of birds] I've ever found at McCormick in one night is 250, which seems massive to start with,” says David Willard, a retired collection manager at Chicago’s Field Museum, who is still involved with the institution.How Ma ...read more
Humans have sophisticated senses that have been well-developed over time. We have an excellent sense of sight — thanks to retinal photoreceptors (rods and cones). We also have a strong sense of hearing that ranges between 20 to 20,000 hertz. Along with that, we have a robust sense of smell that helps us detect dangers such as fire and if food has gone bad. While we have sharpened senses, there are many animals that surpass us. In fact, animals possess some impressive senses that people don’ ...read more
When you buckle up for a road trip or brace for takeoff, the deep connection you’ve formed with your furry sidekick can stay intact as they accompany you for adventures. But what happens when some modes of transportation pose a health risk for your four-legged friend? Are Some Pet Breeds at Greater Travel Health Risks?(Credit:OlgaOvcharenko/Shutterstock) Certain dog and cat breeds are at greater health risks during air travel. Breeds with snubbed noses tend to have short nasal passages, which ...read more
Sending humans to Mars has always seemed a distant dream. But in recent years, cheap access to space, the steady arrival of Mars rovers to explore the surface and the ambitions of billionaires like Elon Musk have made the Red Planet feel almost within reach.All concerned are aware of the huge challenges — from developing the technology to support life during the journey and to safely deliver them to the surface, to bringing them home again. This will be one of the greatest expeditions in human ...read more
