Distant blazar OP 313 emits very high-energy gamma rays above 100 GeV
June 3, 2026 report Distant blazar OP 313 emits very high-energy gamma rays above 100 GeV Tomasz Nowakowski Author Stephanie Baum Scientific Editor Robert Egan Associate Editor An international team of astronomers have employed one of the Large-Sized Telescopes (LSTs) at the Cherenkov Telescope Array Observatory (CTAO) to observe a distant blazar known as OP 313. Results of the observational campaign, published May 26 on the arXiv preprint server, shed more light on the behavior and nature...
Short videos may hinder learning by fragmenting attention and memory, study finds
June 4, 2026 feature Short videos may hinder learning by fragmenting attention and memory, study finds Ingrid Fadelli Author Stephanie Baum Scientific Editor Robert Egan Associate Editor Recent technological advances and the introduction of new digital media platforms have dramatically changed how people learn and source information about topics that interest them. Some recent studies have found that while browsing online or scrolling down social media platforms, users tend to spend under...
Warming unlocks ancient carbon in Tibetan permafrost, triggering climate tipping point
Warming unlocks ancient carbon in Tibetan permafrost, triggering climate tipping point Tejasri Gururaj Author Stephanie Baum Scientific Editor Robert Egan Associate Editor A new study in Nature Communications finds a critical climate tipping point in Tibetan permafrost ecosystems. Warming of 2–4 degrees Celsius triggers a self-reinforcing cycle of carbon release that could significantly accelerate climate change, according to the work. Permafrost covers roughly 15% of the Northern...
Q&A: Why do telomeres shorten when a cell divides, and how does it affect human aging?
Q&A: Why do telomeres shorten when a cell divides, and how does it affect human aging? Stephanie Baum Scientific Editor Andrew Zinin Lead Editor In each cell of your body, DNA is stored in structures called chromosomes.
Why doesn't coffee taste like caffeine?
Why doesn't coffee taste like caffeine? Stephanie Baum Scientific Editor Robert Egan Associate Editor Though decaf fans might disagree, caffeine is a critical component of a cup of joe. This compound is incredibly bitter on its own, but regular coffee itself is not.

We can predict space weather—what if we could also stop it? Stephanie Baum Scientific Editor Robert Egan Associate Editor The weather on Earth can get pretty messy sometimes. But in space, it can be wild, and the effects can be far-reaching.
Ötzi the Iceman and his microbiome—a 5,300-year-old relationship
Ötzi the Iceman and his microbiome—a 5,300-year-old relationship Stephanie Baum Scientific Editor Robert Egan Associate Editor Researchers at Eurac Research have obtained a detailed picture of the microbial community associated with Ötzi, Europe's oldest known natural human mummy. The study provides insights into a complex microbiome, ranging from the gut flora of a Copper Age human to cold-adapted yeasts. Using a variety of samples and methods, the researchers were able to differentiate...
Rainfall near 700 mm marks turning point in ecosystem nitrogen retention
Rainfall near 700 mm marks turning point in ecosystem nitrogen retention Stephanie Baum Scientific Editor Andrew Zinin Lead Editor In a study published in Nature Geoscience, a research team led by Prof. Liu Lingli from the Institute of Botany of the Chinese Academy of Sciences (IBCAS) has identified a mean annual precipitation (MAP) threshold of approximately 700 mm, beyond which the dominant controls on ecosystem nitrogen retention shift. Researchers used naturally occurring soil nitrogen...
Wading bird populations in the New York–New Jersey Harbor are in decline
Wading bird populations in the New York–New Jersey Harbor are in decline Stephanie Baum Scientific Editor Robert Egan Associate Editor Urban estuaries can support thriving ecosystems despite bustling human activity. Noting that bird populations can serve as a key indicator of environmental health, researchers recently investigated trends in the New York–New Jersey Harbor, home to the largest breeding population of colonial nesting wading birds (herons, egrets, ibises) in the northeastern...
Sharks thrive in hotspots of prey, underlining need for holistic approach to conservation
Sharks thrive in hotspots of prey, underlining need for holistic approach to conservation Stephanie Baum Scientific Editor Robert Egan Associate Editor Sharks need healthy habitats, and some have a strong preference for locations jam-packed with food, according to FIU research. A recent study of Caribbean reef sharks in the Bahamas, where shark fishing has been banned for years, shows that the sharks don't seem to like places where prey is hard to find. Instead, they prefer to live where...
