According to the Centers for Disease Control and Prevention (CDC), more than half of American adults take at least one type of supplement. Supplement usage typically increases as people age, with almost a quarter of people over 60 taking four or more supplements. However, supplements can have side effects, can be costly, and can interact negatively with medications. For some people, diet and lifestyle modifications can be a way to achieve positive health benefits instead of relying on supplement ...read more

As global temperatures climb higher year after year, the Earth heads toward a new era marked by a prospective breach of the Paris Agreement. Signed in 2016, the international climate treaty set a limit to keep global surface temperatures from rising 1.5 degrees Celsius (C) (2.7 Fahrenheit) above pre-industrial levels, but two new studies warn that the world may be on its way to failing this critical test. Recent temperature data reflect a turn for the worse, as 2024 became the first year in whi ...read more

A recent fossil find fills in a glaring prehistoric bird gap. The Jurassic period claims Archaeopteryx (sometimes called adeinonychosaurian dinosaur), which, despite their feathered wings, appear more dinosaur like. Meanwhile, most Cretaceous avian progenitors appear more birdlike, with short tails ending in a compound bone called a pygostyle.A team from the Chinese Academy of Sciences report in the journal Nature found a specimen that fits between those proto birds. This finding suggests that t ...read more

It can be hard to keep up all that sugar and spice in your relationship. We get busy with jobs and kids and endless to-do lists, but according to experts, you get what you give when it comes to your relationship. Being kind and loving on a regular basis is one of the most important components of a healthy relationship, says Jacqueline Olds, M.D., an associate professor of clinical psychiatry at Harvard Medical School and co-author of Marriage In Motion: The Natural Ebb And Flow Of Lasting Relat ...read more

The Magdalenian peoples of the European Ice Age left little of themselves behind. Today, their bones are few and far between, found typically in isolation and in fragments. But the remains from one 18,000-year-old assemblage tell us one thing: The Ice Age was a tough time to have enemies. Assessing the markings on Magdalenian remains from Maszycka Cave in southern Poland, a team of researchers has determined that the Magdalenian peoples dissected and cannibalized their dead around 18,000 years a ...read more

A recent study revealed that Earth’s inner core is slowing down, prompting scientists to investigate further. Their research led to an unexpected discovery: that inner core is not entirely solid.Scientists from the University of Southern California (USC) analyzed data from earthquakes and identified unexpected changes in the core's composition, offering insights into why these shifts are occurring.A Slowing Core and Its EffectsIn June 2024, USC scientists published a study showing that Earth� ...read more

The human body is, on average, 60 percent water. So it makes sense that water is doing something important in there. And indeed, water is necessary for almost all physiological processes. In the past few years, research on hydration has shifted from studying the role of hydration in athletic performance to water’s role in overall health. And scientists are finding some interesting connections.Water Is Essential to the BodyThere is evidence that insufficient hydration can cause inflammation, s ...read more

We process our world differently when we’re stressed out, and so, too, do mice. According to a new paper in PLOS Biology, mice perceive sounds in a different way when they’ve been subjected to repeated stressors, responding to some louder sounds as if they were softer. “We found that repetitive stress alters sound processing,” the study authors stated in their paper. “These alterations in auditory processing culminated in perceptual shifts, particularly a reduction in loudness percepti ...read more

After noticing a fish with striking red stripes under its eyes, Chinese scientists knew they’d identified a new species. The fish — a species of tilefish — appears to be wearing red face paint and thus has been named after San, a character from Princess Mononoke, a Studio Ghibli film. With this rare find, researchers are hoping to learn more about this genus and further investigate the species genetic diversity. The findings were recently published in ZooKeys.“Finding a new species in ...read more

Until recently, civilization (as a whole) had never endured severe climate change at global scale. Individual cultures, on the other hand, have confronted regional climate shifts time and again, and for the people involved, they’ve been no less devastating. In fact, many of those cultures collapsed in the turmoil of fluctuating temperatures and dwindling precipitation (and, surely, other political and economic factors). From the deserts of the Middle East to the rainforest of Central America, ...read more
