Rising global temperatures and shifting tectonic plates are believed to have shaped the development of one of Earth’s most iconic trees, the oak (Quercus). According to reports, the Paleocene-Eocene Thermal Maximum (PETM), a significant climatic event approximately 56 million years ago, created extreme conditions that influenced the evolution of diverse plant species, including the ancestors

Rocket Lab’s planned mission to deploy a radar-imaging satellite for the Japanese company Synspective faced a setback when the launch attempt on December 20, 2024, was postponed. The Electron rocket, scheduled to lift off from Rocket Lab’s New Zealand site, was grounded approximately 17 minutes before the planned launch. The company attributed the delay to
Research published in Astronomy & Astrophysics has cast doubt on the supposed discovery of an intermediate-mass black hole in the star cluster Omega Centauri. Initial findings suggested a black hole with a mass equivalent to 8,200 times that of the Sun resided at the cluster’s core. However, a reanalysis indicates the high-velocity stars in this
Fossilised plant remains unearthed near the now-abandoned town of Rainbow, Utah, have defied classification. The plant, named Othniophyton elongatum, was initially discovered in 1969, but recent analysis has shown it is unrelated to any known plant families, living or extinct. The fossil, dating back around 47 million years, was preserved in the Green River Formation,
A new pulsar, PSR J1922+37, has been discovered with a spin period of 1.92 seconds using the Five-hundred-metre Aperture Spherical Radio Telescope (FAST) in China, according to a report. The finding was made in the direction of the open cluster NGC 6791. If confirmed as a member of this cluster, it would be the first
In The Astrophysical Journal, a University of Michigan-led study detailed how the Sun’s magnetic field evolves as it moves through space, providing insights into solar wind acceleration. Using data from rare alignments of the Parker Solar Probe and Solar Orbiter, researchers observed that the Sun’s magnetic field transitions from sharp oscillations to smoother waves, with
Bronze statues, including depictions of snakes and a child priest, have been uncovered from a hot spring at San Casciano dei Bagni in Italy, according to the Italian Ministry of Culture, as per reports. The site, located around 120 kilometres northwest of Rome, has been excavated since 2019 and is believed to have been used
Pipes designed to enable one-way liquid flow without the use of valves have been developed, drawing inspiration from the intestinal structure of sharks. Tesearchers at the University of Washington have created tubes featuring an internal helix, which mimics the corkscrew-shaped intestines found in sharks. This design may pave the way for more durable fluid transport
New research on PDS 70b, a forming exoplanet located approximately 400 light-years away in the constellation Centaurus, suggests that prevailing models of planet formation may require revision. According to a study published in Astrophysical Journal Letters, astronomers found a mismatch between the chemical composition of the planet’s atmosphere and the surrounding protoplanetary disk from which
NASA astronauts Barry Wilmore and Sunita Williams, who embarked on Boeing’s Starliner spacecraft in June 2024, will now extend their stay on the International Space Station (ISS) until March 2025. The return, initially set for February, has been postponed due to a delay in SpaceX’s Crew-10 mission, NASA confirmed on December 17. The decision was
The discovery of 4,000-year-old human remains at Charterhouse Warren in Somerset has unveiled a harrowing chapter of British prehistory. The analysis of over 3,000 bone fragments belonging to at least 37 individuals, ranging from newborns to adults, has indicated an unprecedented level of violence. The findings, published in Antiquity, revealed evidence of scalping, decapitation, defleshing,
SpaceX’s Dragon cargo capsule, part of the CRS-31 mission, undocked from the International Space Station (ISS) on December 16, 2024 at 11:05 a.m. EST, according to reports. The spacecraft, carrying thousands of pounds of research materials and supplies, is expected to splash down off the coast of Florida on December 17. NASA officials confirmed that
NASA’s retired InSight Mars lander was recently spotted by the Mars Reconnaissance Orbiter (MRO) in an image taken on October 23, 2024, using its High-Resolution Imaging Science Experiment (HiRISE) camera. The image shows dust build-up on the lander’s solar panels, which now match the reddish-brown colour of the Martian surface. Reports suggest this observation continues
Permafrost, a frozen layer of soil rich in organic matter, lies beneath 15 percent of the northern hemisphere and is facing significant degradation due to rising global temperatures. According to findings published in Earth’s Future, researchers predict extensive thawing of permafrost by the end of this century. This thawing, influenced by the intensifying greenhouse effect,
An ancient silver amulet, discovered in a third-century grave near Frankfurt, Germany, is being hailed as a groundbreaking find that reshapes perspectives on the spread of Christianity in the Roman Empire. According to a study published by the Leibniz Center for Archaeology (LEIZA) on December 11, the artefact, dated between AD 230 and 270, contains
After a demanding ascent spanning several months, NASA’s Perseverance rover has successfully reached the top of Jezero Crater’s rim, as confirmed during a media briefing held on December 12 at the American Geophysical Union’s annual meeting in Washington. The climb covered a vertical rise of 500 metres and involved navigating steep grades of 20 percent.
