Rare Footage Of Baby Polar Bears Emerging From Den Captured By Scientists
Female polar bears give birth in December or early January when the cubs are blind, hairless and weigh just 0.5 kg.

Polar Bear Fur's Natural Oil Prevents Ice Build-Up, Study Finds
Scientists have uncovered a surprising feature of polar bear fur: a natural oil that prevents ice accumulation. Unlike penguins, which rely on feather structure, polar bears benefit from a chemical composition that keeps their fur ice-free. A study published in Science Advances found that unwashed polar bear fur performed as well as high-performanc...

New Link Found Between Ferroelectric Domain Walls and Superconductivity in 2D Materials
Scientists from the University of Cambridge and Argonne National Laboratory have uncovered a link between ferroelectric domain walls and superconductivity in 2D materials. Their study shows how specific structural features enhance electron-phonon interactions, especially in materials like molybdenum ditelluride (MoTeâ‚‚), paving the way for new sup...

Polar Bears in Alaska Face Rising Pathogen Threats Due to Climate Change
Polar bears in the Chukchi Sea are increasingly exposed to pathogens like Toxoplasma gondii, brucellosis, and canine distemper due to warming climates. Researchers revealed a significant rise in pathogen antibodies in polar bears since the 1990s, linking this trend to reduced sea ice, altered diets, and human interaction. The findings raise concern...

Scientists Discover New Electric Field in Earth’s Atmosphere Crucial for Life
Scientists have finally detected the long-predicted ambipolar electric field in Earth's atmosphere. Though weak, it plays a crucial role in shaping the planet’s upper atmosphere, impacting the polar wind and potentially contributing to Earth’s habitability. This discovery could help explain why Earth’s atmosphere has remained conducive to lif...

Mars Gravity Maps Shows Strange Hidden Structures Underneath the Surface
Scientists have unveiled a new gravity map of Mars, revealing hidden structures beneath the surface and active processes affecting Olympus Mons. The map, presented at the Europlanet Science Congress 2024, challenges traditional geological models and shows dense structures under Mars' northern polar plains. Researchers suggest that a mantle plume mi...

Scientists Uncover Invisible Ambipolar Electric Field Around Earth for First Time, New Study Reveals
Scientists have made a groundbreaking discovery by detecting and measuring the ambipolar electric field around Earth for the first time. This field, hypothesised over 60 years ago, was observed during the Endurance rocket mission launched by NASA in May 2022. The ambipolar field, located in the ionosphere at around 250 kilometres above Earth's surf...

"Something Unusual...": Scientists Warn Of Potential Antarctic Vortex Split
Scientists warn that repeated wind slowdowns could lead to a sudden and dramatic change in the vortex's direction.

The Day After Tomorrow Was Just A Warm-Up. Real Danger Looms, Warn Scientists
A new study has revealed that predicting the timing of catastrophic climate events, such as the collapse of the Atlantic Meridional Overturning Circulation (AMOC), is extremely difficult.

Russian Polar Scientist, Parliament Veteran Artur Chilingarov Dies At 84
Artur Chilingarov, a Russian polar scientist and explorer and veteran member of parliament, died on Saturday, the speaker of the state Duma lower house said. He was 84.

Explained: Earth's Polar Vortex Spins Backwards, Scientists Taken Aback
Scientists were taken aback, earlier this month, when they noticed that the Arctic's polar vortex has changed its course and has started spinning in the opposite direction.

India's 1st Antarctic Mission Top Secret, Felt Like James Bond Film: Scientists
Forty years after India set up its first scientific base station in Antarctica, the researchers associated with the mission on Friday recalled how the country's first expedition to this polar region was kept under wraps from everyone.

Italian Vessel In Antarctica Reaches New Destinations As Polar Ice Melts
An Italian ice-breaker carrying scientists researching in the Antarctic has sailed further south than any ship has done before, the organisers of the voyage said on Tuesday, a further sign of how ice is retreating around the poles.

Scientists Have Found New Evidence For Liquid Water On Mars. Details Here
An international team of researchers has found new evidence for the possible existence of liquid water beneath the south polar ice cap of Mars.

NASA's New Horizons Data Helps Identify a Possible Source for Pluto's Moon Charon's Red Cap
NASA's New Horizons mission data along with novel laboratory experiments and exospheric modelling has helped scientists to reveal the likely composition of the red cap on Pluto's moon Charon and how it may have formed. The team realistically replicated Charon surface conditions to measure the composition and colour of hydrocarbons produced on Charo...
