called intermittent hypercapnia. This involves breathing air with a slightly higher level of carbon dioxide for short periods, followed by normal air. This technique has been used before to study blood vessel health. In this study, it became a tool to...

an intermediate host, amplifying the virus and facilitating its spread to farm workers. Since then, outbreaks have appeared periodically in parts of South and Southeast Asia, including Bangladesh and India. Each outbreak has added to scientists’...

and 1972, NASA’s Apollo program carried 24 astronauts to lunar orbit, with 12 of them walking on the Moon’s surface. That period marked an extraordinary chapter in space history. Since then, no human has traveled that far from Earth. Artemis II is meant...

43 to 53 thousand calibrated years. Taken together, Level 3 likely formed during MIS 4 or early MIS 3, a cold and dry period in the Late Pleistocene. That places the accumulation firmly within the time of Neanderthals. Repeated Behavior, Not a Single...

in the call, the thyroid cartilage tilted, and the vocal folds began vibrating. That produced the lower fo component. For a period, both mechanisms operated together. Statistical analysis showed only a weak correlation between fo and go. That suggests...

it out of the way? The mission succeeded almost immediately. Observations showed that the collision shortened the orbital period of the asteroid moon Dimorphos around its larger companion Didymos by about 33 minutes. But scientists suspected something...

prime location in the search for past life. Some of the rocks visible in the panorama date back billions of years, during a period when Mars was still developing its crust and experiencing frequent asteroid impacts. In a NASA video released alongside...

began. While it shares some characteristics with standard cogs, it also exhibits features that are not typical of the period. The ship’s hull was sealed with pitch-covered animal fur, rather than the usual moss, and certain plank configurations were not...

for twilight photography. Later in the month, the so‑called Buck Moon reaches full illumination on July 29. Named for the period when male deer grow new antlers, this full Moon appears especially large near the horizon, a visual effect amplified by the...

June 8 sea‑surface height map attracted attention because the western Pacific patterns resembled those observed in the same period of 1997, a year that produced one of the strongest El Niños on record. Severine Fournier, deputy project scientist for...

length, as reported in the journal Palaeontology. The fossils date back roughly 415 million years to the Early Devonian, a period when vertebrate life had only just begun to venture onto dry ground. At that time, terrestrial ecosystems were dominated by...

also reported a reduction in incontinence and an overall improvement in quality of life throughout the observation period. The authors acknowledge substantial limitations: observations were primarily caregiver‑reported, lacking objective cognitive...

a peak three‑hour Kp index of 5.67 between July 2 and July 4, corresponding to a G2 (moderate) storm. The most intense period is projected for 00:00‑03:00 UTC on July 4, with G1‑level conditions likely throughout July 3. Under G2 circumstances, the NOAA...

terrain, erasing portions of the ancient surface while burying others, which may further complicate the search for early‑period artifacts.

stems from several Indigenous peoples who noted that young male deer begin to sprout new antlers during this midsummer period. The Algonquin peoples called it the “Raspberry Moon,” highlighting the ripening of local fruit, while the Cree referred to it...

boats during ritual ceremonies. Radiocarbon analysis dates the assemblage to the 8th–10th centuries CE, aligning with the period of Tiwanaku’s territorial expansion. Among the recovered items were the remains of at least seven juvenile llamas,...

a small ceramic pot and hidden for more than two thousand years, may represent payments made to mercenary forces during the period of conflict between Persian and Athenian armies. The find emerged in 2023 during fieldwork by scholars from the University...

tools, animal bones, and environmental signatures that help reconstruct human behavior during the Late Pleniglacial, a period marked by rapid climatic shifts. Tiny Fossils Pinpoint the Age of the Mammoth House Rather than dating the massive bones...

participants to be free of any dementia diagnosis and qualify for shingles vaccination. Over a four‑year observation period, the researchers observed that individuals receiving at least one of the two Shingrix doses experienced a markedly reduced...

body, while a kilometre‑scale rock could receive enough momentum change to be steered away, provided a sufficient warning period exists. The authors estimate that a velocity shift of roughly one metre per second may be enough to miss Earth when applied...
