Climate change is affecting the environments in which we live more and more every year. Along with that, these drastic changes are starting to take a toll on our mental health, as well, especially for young adults. An international research team has taken an interest in what kind of effects climate change is having on adolescent mental health, and the results they have uncovered are concerning. A Mental Health CrisisIn a study published in the Journal of Climate Change and Health, researchers ...read more

Mount Spurr, just to the west of the city of Anchorage, is rumbling. The Alaska Volcano Observatory has been monitoring the earthquakes, gas emissions and visible changes at Spurr and think we might be headed towards a new eruption, the volcano's first since the early 1990s. They've placed it at Yellow Alert status thanks to all the unrest since the start of 2025.More potentially active volcanoes are located in Alaska than any other state in the US thanks to the long chain of the Aleutians that ...read more

Birds-of-paradise are among the most resplendent creatures on Earth, with long, elaborate feathers in eye-popping shades of yellow, blue, and red. Naturalists have admired them for centuries. Yet it turns out they didn’t know the half of it.As if those vibrant colors weren’t enough, a recent study found that the birds — native to Australia, Indonesia, and New Guinea — are also biofluorescent. Their skin and plumage absorb light at high-energy wavelengths, then re-emit it at low-energy wa ...read more

The evolutionary path leading to the rise of modern humans is full of twists and turns, and the latest surprise reveals that our species likely sprung forth from two ancient intermingling populations. A new study has confirmed that these groups first diverged from each other around 1.5 million years ago and later merged back together 300,000 years ago, initiating a genetic mixing event that culminated with the birth of modern humans. The study, published in Nature Genetics, completely rewrites ...read more

We give blood to save someone else’s life. It turns out that this altruistic act could also improve the donor’s health. But they might have to give a lot of blood over time for that effect.A study screened 217 male volunteer blood downers. The researchers divided the group into two. One cohort had given blood over a hundred times during their lifetimes. The other group had done so less than five times.Although the study was initiated in part to investigate whether long-term donation had any ...read more

New findings from the Atacama Cosmology Telescope (ACT) collaboration may have just unveiled the sharpest images of the universe as an infant. After measuring light that traveled 13 billion light years to Earth, the images reveal the universe at about 380,000 years old — the equivalent of an image of a human baby only mere hours old. The new findings come from several international pre-peer-reviewed studies, set to be presented later in March 2025. According to the study researchers, this vie ...read more

Cancer is the second leading cause of death in the U.S., claiming around 600,000 lives in 2022 alone. A diagnosis can be devastating, as the disease can often resist treatment and spreads uncontrollably.Now, a research team from The Jackson Laboratory (JAX) and UConn Health has identified a potential therapeutic strategy to halt or reverse tumor growth. Their study, published in Nature Communications, reveals how cancer cells disable a built-in "off switch" — and how reactivating it could stop ...read more

A 30,000-year-old vulture feather represents a “two-for-the-price-of one” discovery: the fossil itself, and the first evidence that volcanic ash can preserve such soft tissues in exquisite detail.The feather itself is not a new find; a Roman landowner in 1889 came across evidence of entire bird preserved as a three-dimensional impression. Its details included eye lids and wing feathers. However, new research published in the journal Geology demonstrates that preservation extends to microscop ...read more

Sitting in traffic can expose a driver to intense irritation, as well as a range of sound frequencies. Humming engines typically emit low-frequency sounds, while car horns release high-frequency blasts. Emergency vehicle sirens are high-pitched, and the rumblings from large trucks are lower-pitched.For most people, their ears are able to process these wide-ranging sounds and make sense of them. However, scientists don’t have a full sense of why this happens because they are still working to un ...read more

Gas emissions, earthquakes, and ground deformations. These are all signs that a volcano is about to erupt, and they are also all signs that have appeared at Mount Spurr, an active volcano in southcentral Alaska, around 80 miles west of Anchorage.According to the team at the Alaska Volcano Observatory, “significantly elevated” emissions of volcanic gas have been detected at the volcano — the tallest in the Aleutian Arc — this month, along with elevated earthquake activity and ground defor ...read more
