New research suggests that the tiny human species – that survived until about 18,000 years ago, later than any human species other than our own – evolved its small size remarkably quickly while living on an isolated island.

Glaciers are melting in many places on Earth today. But glacier loss in the Peruvian Andes is happening particularly rapidly. New research reports a reduction of almost 30% between 2000 and 2016.
Tropical glaciers exist in the high altitudes of more than 4000 meters around the equator. Peru is home to 92 percent of all glaciated areas in the tropics. Pictured: Cordillera Apolobamba Image via Thorsten Seehaus.

Research involving a non-invasive scan of living human embryos shows that some muscles, thought to have been abandoned by our mammalian ancestors 250 million years ago, are still present before birth. They’re among the oldest, albeit fleeting, remnants of evolution yet seen in humans.

The coming full moon – Hunter’s Moon for the Northern Hemisphere – is October 12-13. Will it be bigger, brighter, more colorful? All you need to know here.
The November full moon is also called the Beaver Moon. You can see all the full moon names here. Maggie NY wrote, "November's Beaver Moon over NY."
Our global human population was estimated to reach 6 billion on today’s date in 1999. Eleven years later, in 2011, Earth had gained another billion people. Today – October 12, 2019 – it stands at about 7.7 billion, according to United Nations estimates.
A new study suggests that about 4,000 years ago, a combination of isolation, extreme weather, and the arrival of humans on Wrangel Island in the Arctic Ocean killed off Earth’s last population of mammoths.

On average the ocean is 2.3 miles (3.7 km) deep, but many parts are much shallower or deeper. In the deepest zones, life forms have adapted to live in the dark, under crushing water pressure.

The Cassini mission to Saturn is over, but scientists still pore over its data. The newest discovery is of organic compounds – the ingredients of amino acids, the building blocks of life – in water vapor plumes from Saturn’s moon Enceladus.
The geysers of Saturn’s moon Enceladus. These huge plumes of water vapor erupt through cracks at Enceladus’ south pole. The Cassini spacecraft analyzed the plumes and found they contain water vapor, ice particles, salts, methane and a variety of complex and simple organic molecules. Scientists believe they originate from an ocean below the moon’s icy crust. Image via NASA/JPL-Caltech/Space Science Institute.
