Highly Energetic Electrons Hit Earth from an Unusual Nearby Source

Physics /

Astrophysicists have detected the highest-energy electrons ever recorded, raining down on Earth from a mysterious nearby source. These cosmic rays carry trillions of times the energy of visible light, suggesting they originate from a powerful source relatively close to our solar system. Earth is constantly bombarded by cosmic radiation, primarily from our Sun. However, other […]

Why Preserving Muscle Mass Is Crucial for Healthy Aging

Biology, Science /

We all wish for a longer life—at least, I know I do—but what about ensuring that we enjoy good health during the time we have? Over the past century, human life expectancy has significantly increased for several reasons, particularly advances in sanitation, public health, nutrition, and medicine. These improvements have reduced mortality, especially among younger

Study Finds Traffic Noises Boosts Stress and Anxiety Levels

Healthcare, Science /

Manmade noises, like vehicle traffic, can reduce the stress-relieving effects of natural soundscapes, according to a November 27, 2024, study in PLOS ONE by Paul Lintott and Lia Gilmour. Previous research shows natural sounds, such as birdsong, lower blood pressure, heart rate, and stress. In contrast, human-made noises like traffic negatively affect health. In this

Remarkable Fossil Reveals a 12-Million-Year-Old Crocodile

Archaeology, Social /

On Wednesday, paleontologists revealed the fossil of a young marine crocodile, estimated to be 10 to 12 million years old, uncovered in a Peruvian desert. The three-meter-long (nearly 10-foot) gharial, or fish-eating crocodile, was discovered in late 2023 in the Ocucaje Desert, about 350 kilometers (190 miles) south of Lima, in near-perfect condition. “This is

Evidence Found of the Only Known Family Practice of Pong-Term Embalming in Early Modern France

Archaeology, Social /

A team of bioarchaeologists from the Austrian Archaeological Institute, Université de Bordeaux, and Aix-Marseille Université has uncovered evidence of an aristocratic family in France embalming their deceased loved ones for nearly two centuries. Their findings, published in Scientific Reports, mark the first discovery of its kind. While embalming practices have been documented in Ancient Egypt

An Expert Discusses the True Impact of Microplastics on Human Health

Earth Science, Environmental Science /

It’s well-known that enjoying a tasty fish fillet or a seafood platter provides essential nutrients like omega-3s and vitamin D. However, these meals often come with an unwelcome side: numerous micro- and nano-plastics. Plastic particles smaller than 5 millimeters find their way into oceans through human waste, infiltrating the food chain. An Ifremer study estimates

A Galaxy Collision at 3.2 Million km/h

Astronomy, Astrophysics, Planetary Science /

Astronomers have observed a massive galaxy collision in remarkable detail, triggered by a galaxy traveling at 2 million mph (3.2 million km/h), using one of Earth’s most powerful telescopes. The dramatic event occurred in Stephan’s Quintet, a galaxy group discovered nearly 150 years ago, and sparked a shockwave resembling a “sonic boom from a jet

Air Fryers Found to Be the Least Polluting Cooking Method

Earth Science, Environmental Science /

Air fryers emit significantly less indoor air pollution than other cooking methods, such as pan and deep frying, according to a new study. While cooking is a major source of indoor air pollution, much of the research has focused on air fryers’ energy efficiency, leaving their environmental benefits less explored. Since most people spend over

Pandrug-Resistant Bacteria Emerging From the War in Ukraine are Highly Pathogenic

Microbiology, Science /

Kristian Riesbeck, a professor of clinical bacteriology at Lund University, was approached by Ukrainian microbiologist Oleksandr Nazarchuk for help in assessing antibiotic resistance in bacteria from severely injured, infected war patients. Using samples from 141 individuals, including 133 adults and 8 newborns with pneumonia, the study revealed widespread resistance to broad-spectrum antibiotics. Alarmingly, 6% of
