By studying the body chemistry of hibernating Arctic ground squirrels, researchers have found that the animals are able to recycle their body’s own nutrients to survive during a long, inactive winter.

Large amounts of new particles can form in the valleys of the Himalayas from naturally emitted gases and can be transported to high altitudes by the mountain winds and injected into the upper atmosphere.

The country endured its hottest spring and November on record.

About a month before the start of astronomical summer in the southern hemisphere, vast areas of sea ice were already painted blue with meltwater.

In his first year of graduate school, Rice University biochemist Zachary Wright discovered something hidden inside a common piece of cellular machinery that’s essential for all higher order life from yeast to humans.

Scientists striving to understand how and when volcanoes might erupt face a challenge: many of the processes take place deep underground in lava tubes churning with dangerous molten Earth.

When humans have low iron levels, they tend to feel weak, fatigued and dizzy.

Under the current pandemic conditions, activities out in nature are a popular pastime.

During the last glacial period, app. 10,000 – 110,000 years ago the northern hemisphere was covered in glacial ice and extensive sea ice, covering the Nordic seas.

Astronomers have caught a rare look at a rapidly fading shroud of gas around an aging star. Archival data from NASA’s Hubble Space Telescope reveal that the nebula Hen 3-1357, nicknamed the Stingray nebula, has faded precipitously over just the past two decades.
