companion objects—will help expand the census of these overdense worlds. Detectability of companions to GJ 523b in mass period space. The gray region shows what would have been detected in our current RV data, and the black shows what we likely would...

Beneath the Pacific The temporal analysis revealed significant fluctuations in seismic wave velocity over the 18-year study period. Compared to the 1977 baseline, waves accelerated by approximately 0.1 seconds by 1982-1983 and further by 0.15 seconds...

consensus that their massive size was primarily a result of the high oxygen levels characteristic of the Carboniferous period. Challenging the Oxygen-Driven Growth Hypothesis For decades, researchers have argued that because insects lack lungs and rely...

a newborn, eventually aligning with the molecular profile of a four-year-old child by the end of the five-year observation period. Perhaps most intriguingly, the cells appear to possess an inherent temporal awareness. When the researchers combined cells...

of the find when he observed that the bones were buried eight meters deep, placing them squarely in the transition period between the Lower and Upper Cretaceous. Skeletal reconstruction of Dasosaurus tocantinensis, showing the estimated body size of the...

The team subjected magnetite samples to high-pressure environments and water temperatures reaching 200°C over a 60-day period. The results confirmed that the mineral successfully releases hydrogen gas under these specific conditions. Beyond simply...

both terrestrial and marine animals. These findings confirm a sustained human presence dating back to the Mesolithic era, a period when, contrary to earlier theories, there were no land bridges connecting Malta to the Italian mainland or Sicily. Maps...

researchers could perform detailed atmospheric characterization. Rather than simply confirming a planet’s mass or orbital period, scientists hope to detect the chemical fingerprints of potential habitability. “We’re going for the spectral lines from red...

with females typically giving birth to only a single pup every two to three years following a roughly year-long gestation period. Commercial fishing remains the primary driver of their decline. Whether targeted directly or captured as bycatch in gill...

evidence of 18 burials discovered within the area. Unlike a singular event, these interments occurred over a significant period, indicating that the monument held cultural importance for successive generations who returned to the space long after its...

engravings dating back 24,000 years, alongside evidence of prehistoric modifications to the cave’s stalagmites. The Roman period was first confirmed at the site in 2024, when researchers identified 15 Latin inscriptions and a coin depicting Emperor...

represents the entire phenotypic range of the group. Denisovans occupied a vast geographic range over a significant period, likely exhibiting a diverse array of physical traits as they adapted to different environments and engaged in interbreeding with...

15,000 coins, representing over 100 different territories and centuries of global monetary history. Following a long period of dormancy, the holdings are currently being dispersed through a sequence of high-profile auctions managed by the Zurich-based...

deployed its solar arrays and instrument sun shade. Over the next three months, the craft will undergo a rigorous period of calibration and systems testing before it begins its primary mission to survey the cosmos. Nancy Grace Roman stands in front of a...

animal’s true lineage. The specimen, identified as Tamirkhan balcarceli, is a small creature dating back to the Cretaceous period. Its discovery, detailed in a new study published in Nature, forces a reclassification of zhelestids. Rather than being...

how supermassive black holes achieved such immense proportions in the early universe. These findings, dating back to a period between 12.5 and 12.8 billion years ago, suggest that these rapidly feeding black holes were already congregating in...

data indicated that reintroduced tortoises maintained a survival rate of over 80 percent across a four-year study period. Another initiative at the Réserve de Bandia successfully grew a population from eight to 22 individuals over the course of a...

A Multi-Millennial Tradition Radiocarbon analysis indicates that the turtle figurines were deposited over an extensive period, spanning from roughly 14,500 B.C.E. to 11,200 B.C.E. According to Deniz Sarı, a professor of archaeology at Bilecik Şeyh...

unaccustomed to such deluges. In the town of Taltal, roughly 40 millimeters (1.6 inches) of rain fell over a three-day period. Garreaud noted that this total represents approximately ten times the city’s average annual precipitation, describing the...

shorten the development time of the embryos, which typically takes about four years. By accelerating the gestation period, the volcanic heat increases the likelihood of juvenile survival. Once the young skates hatch, they use the coral-rich summit as a...
