It can cause serious health problems. Three-quarters of adults in the APA survey said they’ve experienced headaches, fatigue, or felt nervous or anxious because of stress. Stress can have adverse effects ...read more

It’s Women’s History Month AND we’re just two short weeks from Citizen Science Month. And that’s why we have Rosie the Robot urging everyone to roll up their sleeves and do their part by signing up for the One Million Acts of Science Challenge! If we all work together We Can Do It!Portrait of Maria Mitchell, ca. 1851, painted four years after Mitchell achieved fame for discovering what came to be known as "Miss Mitchell's Comet."

Magnesium is an essential mineral that’s integral to our health. The human body doesn’t produce magnesium, so we must get it from food or supplements. Found naturally in seawater, salt lake brines, crustal rocks, and deposits, magnesium makes up 13 percent of Earth’s mass and is the eighth most abundant element in the planet’s crust. There are varying estimates of how much of the American population is magnesium deficient — with a wide range spanning from 12 percent to more than 50 per ...read more

In 2019, a fin whale beached itself along the Gulf of California in Mexico. The gigantic creature was so frightened by the team of orcas trying to take it down that it ran itself into the ground on the beach and later died.While there have been only two documented instances of fin whales beaching themselves to escape killer whales, these giant mammals are being attacked more often, according to experts like Robert Pitman, a biologist who specializes in the study of killer whales at Oregon State ...read more

The word “leprosy” conjures images of biblical plagues, but the disease is still with us today. Caused by infectious bacteria, some 200,000 new cases are reported each year, according to the World Health Organization. In the United States, leprosy has been entrenched for more than a century in parts of the South where people came into contact with armadillos, the principle proven linkage from animal to humans. However, the more recent outbreaks in the Southeast, especially Florida, have not ...read more

Gamma rays are weightless, high-energy packets of electromagnetic radiation — the same stuff that makes up light. However, while visible light can comfortably light up a room, gamma rays can penetrate concrete, and cause serious damage to the human body as they pass through. While we may assume we’re safe from the effects of gamma radiation, one particular cosmic phenomenon — gamma-ray bursts — poses a chilling question: What would happen if one of these massive spikes of radiation hit t ...read more

In Argentina, where beef is a symbol of national pride, a government-led partnership has started certifying certain livestockas carbon neutral. It’s a big step that shouldn’t be underestimated, but getting the certification process right is crucial.The world’s livestock sector is a key driver of climate change, contributing around 12% of global greenhouse gas emissions. Two-thirdsof agriculture’s annual greenhouse gas emissions come from livestock, with raising cattle for meat typically ...read more

Is or was there life on Mars? That profound question is so complex that it will not be fully answered by the two NASA rovers now exploring it.But because of the literal groundwork the rovers are performing, scientists are finally investigating, in-depth and in unprecedented detail, the planet’s evidence for life, known as its “biosignatures.” This search is remarkably complicated, and in the case of Mars, it is spanning decades.As a geologist, I have had the extraordinary opportunity to wo ...read more

Imagine opening your front door wide and inviting the world to listen in on your most private conversations. Unthinkable, right? Yet, in the digital realm, people inadvertently leave doors ajar, potentially allowing hackers, tech companies, service providers and security agencies to peek into their private communications.Much depends on the applications you use and the encryption standards the apps uphold. End-to-end encryption is a digital safeguard for online interactions. It’s used by many ...read more

In both December 2023 and February 2024, NASA’s Juno spacecraft soared over Jupiter’s moon, Io. Shooting past at a distance of around 930 miles, the twin flybys — the two closest flybys of Io in over 20 years — produced images of the moon’s lava lakes and volcanic plumes, fleshing out our impression of our solar system’s most volcanic world.According to NASA scientists, the images could contribute to our understanding of Io’s volcanism, confirming the patterns and the origins of th ...read more
