Canadian researchers observed a rare moment in the Arctic as an adult polar bear appeared to tolerate and protect a lone cub, challenging assumptions about the species’ solitary nature.
Courage doesn’t remove fear—it reorders it. By choosing action over avoidance, courage restores agency, builds resilience, and keeps our lives from quietly shrinking.
As climate risks grow, many experts argue that research into solar geoengineering should continue, not to deploy it, but to understand its risks before decisions are forced.
The Trump administration plans to break up the National Center for Atmospheric Research, raising concerns about the future of U.S. weather forecasting and climate science collaboration.
Interstellar comet 3I/ATLAS nears its closest Earth approach (~1.8 AU) on Dec. 19, offering rare observational opportunities with no threat to our planet.
NASA’s Perseverance rover prepares for years of careful travel on Mars, moving slowly and deliberately as it balances science, safety, and long-term exploration goals.
In an extraordinary observation, wildlife scientists have documented a female polar bear adopting an orphaned cub in Alaska, showcasing the intricate maternal instincts often seen in these majestic creatures. This remarkable event, rarely observed in the wild, emphasizes the nurturing aspect of polar bear mothers, who are vital for the survival of their young.
Vast has invited scientists worldwide to propose research for its Haven‑1 commercial space station and related missions, offering access to microgravity environments and orbital science platforms.
As climate risks grow, many experts argue that research into solar geoengineering should continue, not to deploy it, but to understand its risks before decisions are forced.
Ten years after the Paris climate agreement, global emissions are still rising, highlighting progress in policy and renewables but a widening gap between pledges and reality.
Experts warn that a harmful biological growth is spreading rapidly across parts of the U.S., threatening ecosystems, public health, and local communities.
Astronomers have observed a rare cosmic event, AT2025ulz, that may be a first-of-its-kind “superkilonova” — a stellar explosion that happened twice, linking supernova and kilonova traits.
After years of budget threats and political debate, a 4.3 billion dollar space telescope once targeted for cancellation is now complete and preparing for its next steps toward launch.
Researchers warn that if satellite control were lost, a catastrophic collision in low Earth orbit could occur in about 2.8 days, highlighting the urgent risks of orbital congestion and space debris.
A new study warns that Alpine glaciers could reach their highest rate of extinction within eight years as climate change accelerates ice loss, with profound environmental impacts.
Japan is preparing for its first panda-free moment in nearly 50 years as the last giant pandas return to China, closing a long chapter of cultural and diplomatic symbolism.
The Geminid meteor shower of 2025 lit up December skies, offering a calm, steady celestial display that marked the year’s closing nights with quiet beauty.
Scientists document orcas and Pacific white‑sided dolphins hunting salmon together off British Columbia — a rare cooperative behaviour suggesting mutual benefits and shared foraging strategies.
New climate data prompts scientists to reassess how much the Earth has warmed, refining temperature records while reaffirming long‑term warming trends.
A photographer in Italy has captured a rare luminous atmospheric event over his town for the second time, offering scientists and skywatchers a striking glimpse of a fleeting phenomenon.
Scientists detected hundreds of small earthquakes beneath Antarctica’s Thwaites Glacier, raising concern and uncertainty about how the unstable ice mass is responding to stress and warming.
Scientists have sequenced the vampire squid’s genome for the first time, revealing how the deep-sea species evolved to survive darkness, pressure, and low oxygen.
Scientists have found evidence that Earth’s mantle may contain the planet’s largest water reservoir, locked inside minerals and reshaping how we understand Earth’s geology.
Astronomers detected a deep-space explosion lasting nearly seven hours, defying known categories of cosmic events and hinting at a phenomenon never seen before.
