New research on the chemical composition of the ocean has shown that, 3.26 billion years ago, the continents were actually above water. This pieces together several other studies into a cohesive, big-picture idea of how the world once looked, according to Aaron Satkoski and his team of researchers who studied the chemical composition of erosion in the ocean back in 2013 in the Barite Valley, near Barberton, South Africa.

Friday afternoon’s conversation with Dr. Nadia Drake, the Fall 2016 UW-Madison Science Writer in Residence, began with an experiment in which a chemistry professor placed dry ice into six cylinders filled with colorful liquid. Waiting until the chemical reaction stopped, Drake went to the front and poured huge amounts of dry ice into a basin of hot water. Clouds of white fog came out of the container as condensed water vapor.
Welcome back to Sciencecast: Climate Change Series! Twice a month, we will explore various facets of climate change through interviews with UW experts.
Yellowstone National Park is the nation’s oldest national park, spanning one of the largest swathes of wilderness in America. It’s famed for its pristine landscape and iconic wildlife. As UW-Madison’s Eugene P. Odum professor of ecology Monica Turner states, Yellowstone is the “crown jewel” of American national parks. However, Yellowstone’s forests, along with forest ecosystems elsewhere, are in danger of climate change.
The stick hit the puck and the puck glided across the ice. As the blades on his skates did the same, Vaughn Kottler, a now junior at UW-Madison but an incoming high school junior at the time, scurried around the hockey rink at tryouts. Little did he know what was about to hit him.

The College of Agricultural and Life Sciences hosted their third annual local produce showcase dinner called “Farm to Flavor” Thursday evening.
While earthworms are generally welcomed in soils for their ability to break down dead leaves and other organic matter into nutrients the plants can absorb, the invasive Asian jumping worm does so at an astounding rate, potentially accelerating the losses of nutrients from soils and harming native plants.
Dear Ms. Scientist,
Previous UW-Madison research suggests autism can be reliably diagnosed by age two, but fewer than half of children with autism spectrum disorders are being identified in their communities by age five nationwide.
A fourth-year biomedical engineering student at UW-Madison has won the grand prize of an international, GE sponsored, university challenge for his proposed technique to do the impossible.
An assistant scientist at UW-Madison has a developed new design strategy for creating much more stable synthetic collagen, a previously difficult task.
For the general population, satellites are simply there to help watch T.V., text, for the conspiracy theorists, spying or for a Skynet-esque takeover.
Urban heat island effect is a direct result of urbanization, through its conversion of pervious areas, or permeable surfaces that promise the growth of plants, into impervious areas, or hard surfaces like cement sidewalks or parking lots.
In one of nature’s more endearing displays, a panda paws at a narrow, basil-colored stick of bamboo. Propping the chute up like a flute, the panda tries to meander the bamboo into its mouth. It leans back just a little too far, awkwardly rolling onto its back as it gnaws on the chute like a toothless child. After the victorious snap of fiber, the panda props itself up toward the zoo crowd around it, flashing a hint of pride as it goes for another bite.
Wisconsin wildlife is about to take center stage and the Wisconsin Department of Natural Resources (DNR) is preparing to welcome these new celebrities. A new project called Snapshot Wisconsin is aiming to create one of the largest networks of trail cameras to capture Wisconsin wildlife.
A memorial for UW-Madison students that passed away during this academic year was held at the Carillon Tower outside of the William H. Sewell Social Sciences building Friday.
Dear Ms. Scientist,
The earth is warming. Ninety-seven percent of scientists have agreed on the consensus that climate change is real and caused by man.
