Welcome to Science News Daily. I'm your host, bringing you the latest discoveries and breakthroughs from the world of science. Today we're exploring everything from simple health fixes hiding in plain sight to ancient cosmic mysteries finally being solved. Let's dive in.

First up, a surprising finding about blood pressure management. Despite overwhelming evidence that salt substitutes can safely reduce high blood pressure, a new analysis of nearly 20 years of national health data reveals that hardly any Americans actually use them. Usage peaked at just over 5 percent and then declined, even among people with hypertension. Researchers are calling this a major missed opportunity since salt substitutes are both inexpensive and effective. It's fascinating how sometimes the simplest solutions remain the most underutilized.

Moving from Earth to the cosmos, astronomers have solved a 400-year-old mystery about globular clusters, some of the oldest and densest stellar systems in our universe. New simulations suggest these ancient star formations don't just form in one way, but multiple ways. Even more intriguingly, the research points to a mysterious new type of star system that may already be hidden somewhere in our own Milky Way galaxy. It's remarkable how our understanding of these cosmic neighborhoods continues to evolve.

Speaking of space discoveries, the solar wind may be hiding particles that could completely reshape our understanding of space weather. The Magnetospheric Multiscale Mission has delivered the first observational evidence of pickup ions and their related wave activity in the solar wind near Earth. This data could challenge current models of how solar wind evolves, potentially revolutionizing our ability to predict space weather events.

The James Webb Space Telescope continues to amaze us with new insights about potentially habitable worlds. Observations of TRAPPIST-1e, an Earth-sized exoplanet 40 light years away, show no signs of its original atmosphere, but hints of a secondary atmosphere remain. This means liquid water could still exist there, either as vast oceans or beneath an icy surface. Every new piece of data brings us closer to answering that fundamental question: are we alone?

In medical breakthroughs, scientists have solved a rare medical mystery by identifying mutations in the SPNS1 gene as the cause of a previously unrecognized multi-organ disorder. This discovery not only provides answers for affected families but opens potential pathways for treatment. Meanwhile, a Texas hospital is pioneering the use of suzetrigine, a new non-opioid painkiller that provides strong pain relief without the harmful side effects of narcotics. This could be a game-changer in our ongoing fight against the opioid crisis.

Archaeologists have uncovered surprising secrets from a 500-year-old royal warship. The Gribshunden, a Danish-Norwegian flagship that sank in 1495, carried an arsenal of small guns designed for close-range combat. This floating castle didn't just project military might, but also served diplomatic purposes, offering us a rare glimpse into naval power during the late Middle Ages.

In health research, scientists are discovering that the ketogenic diet might affect men and women very differently. Research from UT Health San Antonio shows that estrogen appears to shield females from some of the harmful effects that males experience on keto diets. This finding highlights the importance of considering biological sex in dietary recommendations.

Finally, researchers have made breakthrough discoveries about alcohol's effects on our bodies. Mayo Clinic scientists uncovered how excessive drinking disrupts an enzyme called VCP, which normally prevents harmful protein buildup on fat droplets in the liver. Meanwhile, UC San Diego researchers found that chronic alcohol use blocks a crucial protein that keeps gut bacteria from leaking into the liver, making damage even worse. Both discoveries point toward new treatment approaches for alcohol-related liver disease.

That's all for today's Science News Daily. From simple salt substitutes to complex cosmic mysteries, science continues to surprise us with both practical solutions and mind-bending discoveries. Keep exploring, keep questioning, and we'll see you next time.
