New research from the University of New Hampshire has led to the development of a novel technique to determine the surface area and volume of small particles, the size of a grain of sand or smaller. Due to their tiny size, irregular shape and limited viewing angle, commonly used microscopic imaging techniques cannot always capture the whole object’s shape often leaving out valuable information that can be important in numerous areas of science, engineering and medicine.
Alex McVey, a senior majoring in Earth system science at The University of Alabama in Huntsville (AUH), served as the project lead this summer for NASA DEVELOP’s Rwanda ecological forecasting project.

Lighter-toned bedrock that surrounds fractures and comprises high concentrations of silica—called “halos”—has been found in Gale crater on Mars, indicating that the planet had liquid water much longer than previously believed.
The discovery of anomalously high levels of mercury in rocks from the Ordivician geological period has led to a new interpretation of the ensuing mass extinction. A sequence of disturbances may have led to catastrophic cooling by reflective sulfate aerosols injected into the atmosphere by massive volcanism. The finding is important since aerosol cooling is under consideration as a way to temper global warming.
An international team of scientists has found evidence suggesting the dehydration of minerals deep below the ocean floor influenced the severity of the Sumatra earthquake, which took place on December 26, 2004.

Using radioactive elements trapped in crystallized, cream-colored “veins” in New Mexican rock, geologists have peered back in time more than 400,000 years to illuminate a record of earthquakes along the Loma Blanca fault in the Rio Grande rift. It is the longest record of earthquakes ever documented on a fault.
Recent articles have declared that deposits of mineral raw materials (copper, zinc, etc.) will be exhausted within a few decades. An international team, including the University of Geneva (UNIGE), Switzerland, has shown that this is incorrect and that the resources of most mineral commodities are sufficient to meet the growing demand from industrialization and future demographic changes. Future shortages will arise not from physical exhaustion of different metals but from causes related to industrial exploitation, the economy, and environmental or societal pressures on the use of mineral resources. The report can be read in the journal Geochemical Perspectives.
Special ‘nugget-producing’ bacteria may hold the key to more efficient processing of gold ore, mine tailings and recycled electronics, as well as aid in exploration for new deposits, University of Adelaide research has shown.
Explorers planning to settle on Mars might be able to turn the planet’s red soil into bricks without needing to use an oven or additional ingredients. Instead, they would just need to apply pressure to compact the soil—the equivalent of a blow from a hammer. These are the findings of a study published in Nature Scientific Reports on April 27, 2017. The study was authored by a team of engineers at the University of California San Diego and funded by NASA.
University of Iowa volcanologist Ingrid Ukstins spent two weeks collecting samples from Yasur, a continuously erupting volcano on Tanna, an island in the remote South Pacific archipelago of Vanuatu, to study its chemical composition and determine how the gasses it produces may be affecting people who live nearby.
Agronomy is the study of crop and soil science – important in delivering food from farm to table. But most people don’t know the word. And most agronomists – the scientists working in the field of agronomy – find their complicated jobs hard to explain. That means there is a communication gap, and Nels Hansen wants to help solve it.
