New Bacteria Groups, and Stunning Diversity, Discovered Underground

Berkeley Lab and UC Berkeley research also provides new clues about the roles of subsurface microbes in globally important cycles

One of the most detailed genomic studies of any ecosystem to date has revealed an underground world of stunning microbial diversity, and added dozens of new branches to the tree of life. (more…)

Gas Injection Probably Triggered Small Earthquakes Near Snyder, Texas

AUSTIN, Texas — A new study correlates a series of small earthquakes near Snyder, Texas between 2006 and 2011 with the underground injection of large volumes of gas, primarily carbon dioxide (CO2) — a finding that is relevant to the process of capturing and storing CO2 underground.

Although the study suggests that underground injection of gas triggered the Snyder earthquakes, it also points out that similar rates of injections have not triggered comparable quakes in other fields, bolstering the idea that underground gas injection does not cause significant seismic events in many geologic settings.

The New Face of Mining: Women Carving Out a Place in Surging Industry

The UA department of mining and geological engineering, one of only 14 U.S. schools offering mining engineering degrees and only a handful with its own student mine, is dedicated to helping fill the industry pipeline, and that includes ensuring female engineers continue to gain ground in a surging industry.

They roam the remotest corners of the world, scale the highest mountains and descend deep into the Earth.

They go places few women have ever gone. They are not afraid of getting dirty, or of much else for that matter, certainly not adversity or a good challenge. And they know, better than most, how and when to take a joke. (more…)

New App Keeps Londoners in the Loop about the Tube

A new app for android phones allows Londoners to share their experiences about the London Underground as they travel, and could transform how we use public transport.

The new application, called Tube Star, has been developed by researchers at UCL and aims to capture the experience of being in the tube, as reported by passengers. The app’s designers hope that it will give travellers a way of sharing their knowledge as well as improving our understanding of what happens when things go wrong – or right – on the underground.

The Search for Dark Matter Goes Deeper Underground

With LUX ZEPLIN Berkeley Lab researchers seek to increase the sensitivity of LUX, the most sensitive search for dark matter yet, by orders of magnitude

Although it’s invisible, dark matter accounts for at least 80 percent of the matter in the universe. No one knows what it is, but most scientists would bet on weakly interacting massive particles, or WIMPs.

LUX, the Large Underground Xenon detector at the Sanford Underground Research Facility in the Black Hills of South Dakota, is calling that bet with a titanium bottle holding 350 kilograms of liquid xenon, placed in a cavern 4,850 feet down in the former Homestake gold mine. LUX is a trap set for dark-matter WIMPs. (more…)
