Going subterranean: Repurposed mines become innovative labs

Around the world, old mines are finding new life as underground research facilities, offering scientists unique ways to answer some of science’s biggest questions — from investigations of natural resources, seismic activity and carbon sequestration, to less obvious topics like biofuel development and how life began on Earth — and, maybe, on other planets as well.

Solar eclipse mimics conditions on Mars

What does a total solar eclipse here on Earth have to do with studying life on Mars? The answer lies nearly 25 kilometers above Earth’s surface in the stratosphere, where the August 2017 eclipse offered researchers a rare opportunity to mimic conditions on the Red Planet.

Stable isotopes offer novel methods of disease detection

Stable isotope techniques developed by geoscientists are being applied to studies of human health, and one in particular has shown promise as an improved way to determine bone loss, a problem for astronauts, as well as those on bed rest and aging populations here on Earth.

Silk Road routes may have followed the herds

The Silk Road — the ancient trade route that stretched thousands of kilometers from China to the Mediterranean — often calls to mind images of large camel caravans trekking for months across deserts and over mountains, carrying luxurious linens, spices and gems between distant lands. In reality, the “road” comprised a network of many shorter relays between neighboring areas, with goods often changing hands many times in cities, rural villages and even remote trading outposts. In a new study, researchers have illuminated likely routes of Silk Road travelers through a region of particularly challenging terrain — mountainous Central Asia — with the help of an innovative mapping method.

Soil moisture may help predict power outages in hurricanes

Power outages, most often caused by trees and branches falling on electric lines and transformers, are one of the most debilitating aspects of hurricanes, knocking out power to large numbers of people and businesses. In a new effort to improve modeling of where and when power outages caused by falling trees will occur during hurricanes, researchers are making use of frequent measurements of soil moisture provided by NASA’s SMAP (Soil Moisture Active Passive) mission, which began collecting data in spring 2015.

Improved genetic simulations identify human genes passed down from Neanderthals, Denisovans

You could have your mother to blame for a predisposition to baldness, but you might need to thank a Neanderthal for your ability to fight off disease. In the past decade, researchers have identified a number of genes in the human genome that they believe originated in Homo sapiens’ close evolutionary kin, Neanderthals and Denisovans. Now, a study published in the journal Molecular Biology and Evolution has identified additional traces of such archaic genes in modern human DNA.
