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. The work was led by postdoctoral researcher Randy Williams and his advisor, Laurel Goodwin, a professor in the geoscience department.
An analysis just published online has broken new ground by finding gender differences in both symptoms and diagnoses of depression appearing at age 12. The analysis, based on existing studies that looked at more than 3.5 million people in more than 90 countries, confirmed that depression affects far more females than males.
The goal of UW2020 is to stimulate and support cutting edge, highly innovative and groundbreaking research at UW–Madison and the acquisition of shared instruments or equipment that will open new avenues for innovative and significant research.
Like a lot of pioneering science, the Wisconsin H-Alpha Mapper (WHAM) got its start as the shoestring project of a curious young researcher. Sawing a hole in the ceiling of an office at the University of Wisconsin–Madison’s Physical Sciences Laboratory in the late 1970s, astrophysicist Ron Reynolds pointed a specially built spectrometer skyward for the first time and discovered a previously unknown feature of the Milky Way.
Road salt is making North America’s freshwater lakes saltier, according to a new study published in the Proceedings of the National Academy of Sciences. Most of the lakes tested (284) are in the North American Lakes Region. The study represents the first large-scale analysis of chloride trends in freshwater lakes.
Despite the internet-dependent nature of our world, a thorough understanding of the internet’s physical makeup has only recently emerged, thanks to painstaking work by University of Wisconsin–Madison researchers and their collaborators. Professor of Computer Sciences Paul Barford, Ph.D. candidate Ramakrishnan (Ram) Durairajan and colleagues have developed Internet Atlas, the first detailed map of the internet’s structure worldwide.
On a lab benchtop, a handful of glass vials taped to a rocker gently sway back and forth. Inside the vials, a mixture of organic chemicals and tiny particles of fool’s gold are begging a question seemingly beyond their humble appearance: Where did life come from?
A study that used a new digital library and machine reading system to suck the factual marrow from millions of geologic publications dating back decades has unraveled a longstanding mystery of ancient life: Why did easy-to-see and once-common structures called stromatolites essentially cease forming over the long arc of earth history?
More than three decades of data on the physical, chemical and biological variables in 11 Midwestern lakes show that while lake temperatures and nutrient concentrations rise within relatively expected ranges, organisms achieve high population extremes. The findings challenge preconceptions about what a “normal” distribution of averages and extremes looks like.
