Hidden “electron highways” beneath our feet could revolutionize pollution cleanup

Electrons flow underground in ways far more extensive than once believed, forming networks that link distant chemical zones. Minerals, organic molecules, and specialized bacteria can act as bridges, creating long-distance electron highways. These discoveries hold promise for pollution cleanup strategies, remote remediation, and protecting ecosystems. Scientists now see the subsurface as an interconnected redox system with exciting practical potential.

Earthquakes release blistering heat that can melt rock in an instant

MIT scientists have unraveled the hidden energy balance of earthquakes by recreating them in the lab. Their findings show that while only a sliver of energy goes into the shaking we feel on the surface, the overwhelming majority is released as heat—sometimes hot enough to melt surrounding rock in an instant.

Why Alaska’s salmon streams are suddenly bleeding orange

Warming Arctic permafrost is unlocking toxic metals, turning Alaska’s once-clear rivers into orange, acid-laced streams. The shift, eerily similar to mine pollution but entirely natural, threatens fish, ecosystems, and communities that depend on them—with no way to stop the process once it starts.

GIS-based analysis of fault zone geometry and hazard in an urban environment

Typical geologic investigations of active earthquake fault zones require that the fault can be observed at or near the Earth's surface. However, in urban areas, where faults present a direct hazard to dense populations, the surface expression of a fault is often hidden by development of buildings and infrastructure. This is the case in San Diego, California, where the Rose Canyon fault zone trends through the highly developed downtown.

New flame retardants, old problems

New flame retardants escaping from our TVs, other electrical and electronic products, and children's car seats are just as toxic as the flame retardants they're intended to replace, according to a new study. The authors found that the replacement chemicals, called organophosphate flame retardants, have been associated with lower IQ in children, reproductive problems, and other serious health harms.

Scientists find early humans moved through Mediterranean earlier than believed

An international research team led by scientists from McMaster University has unearthed new evidence in Greece proving that the island of Naxos was inhabited by Neanderthals and earlier humans at least 200,000 years ago, tens of thousands of years earlier than previously believed.
