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

A study currently under review in Climate of the Past has reported that Arctic Siberia experienced summer temperatures up to 10 degree Celsius warmer than today during the Last Interglacial period, approximately 115,000 to 130,000 years ago. Researchers have drawn these conclusions from sediment cores and fossil remains, highlighting how polar ecosystems responded to heightened

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

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

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

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,

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

The innermost planet of the TRAPPIST-1 system, TRAPPIST-1b, may possess a carbon dioxide-rich atmosphere, according to research published in Nature Astronomy on December 16. The TRAPPIST-1 system, which lies 40 light-years from Earth and includes seven Earth-sized exoplanets, has intrigued astronomers since its discovery in 2017. Earlier studies suggested that these planets lacked atmospheres due

A pair of stars, designated D9, has been identified orbiting Sagittarius A, the supermassive black hole at the core of the Milky Way, according to a study published in Nature Communications. This is the first time a binary star system has been detected in close proximity to such an immense gravitational force. The finding 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,

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

The NASA/ESA/CSA James Webb Space Telescope has verified a decades-old mystery regarding planet formation in the early universe. According to The Astrophysical Journal, findings indicate that planet-forming disks around stars endured far longer than previously theorised, even in environments with minimal heavy elements. Reportedly, in 2003, the NASA/ESA Hubble Space Telescope observed the presence of

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

The USS Zumwalt, a stealth destroyer from the United States Navy, is undergoing upgrades to accommodate experimental hypersonic missiles under the Conventional Prompt Strike (CPS) programme. These missiles, capable of speeds exceeding five times the speed of sound, represent a significant advancement in non-nuclear warfare. According to reports, the enhanced capabilities will allow for precise

A humpback whale has undertaken an extraordinary migration spanning over 8,000 miles and three oceans, breaking records for the longest documented journey between breeding grounds. This exceptional voyage, reported in Royal Society Open Science, is believed to be influenced by changing oceanic conditions or evolving mating strategies, as suggested by researchers. According to Professor Darren

A galaxy nicknamed the Firefly Sparkle has been detected by NASA’s James Webb Space Telescope, marking a significant discovery. According to research published in Nature on December 11, this galaxy existed approximately 600 million years after the Big Bang and has a mass similar to the Milky Way at a comparable stage of development. The

Recent research, published in Nature, has raised questions about the volcanic processes occurring on Jupiter’s moon Io, particularly regarding the absence of a global magma ocean beneath its surface. Data collected by NASA’s Juno spacecraft, combined with historical information from the Galileo mission, suggest that Io’s interior is more solid than previously believed. This revelation

The Ingenuity Mars Helicopter, initially deployed by NASA to test the feasibility of powered flight on Mars, has been repurposed as a weather station following a crash that ended its flying capabilities, as per reports. According to updates shared during the 2024 Annual Meeting of the American Geophysical Union (AGU) in Washington, D.C., the helicopter

A major glacial lake outburst flood, among the largest ever recorded, has been documented in East Greenland, releasing more than 3,000 billion litres of meltwater, as per reports. The event, observed by researchers from the University of Copenhagen’s Niels Bohr Institute, took place between September 23 and October 11 and was caused by the sudden
