The complex shape of respiratory syncytial virus is one hurdle limiting the development of treatments for an infection that leads to hospitalization or worse for hundreds of thousands of people in the United States each year, according to the Centers for Disease Control and Prevention. New images of the virus from researchers at the University of Wisconsin鈥揗adison may hold the key to preventing or slowing RSV infections.

Land was once set aside as Native American reservations because it was undesirable and low in resources, but now interested Native Americans may have economic leverage in the growing industry of clean energy. A team of researchers led by UW鈥揗adison professors Dominic Parker and Sarah Johnston quantified the economic potential of wind and solar energy projects on these lands and discussed the regulatory barriers for tribes wishing to tap into it.

A report on more than 40 years of research on Wisconsin lakes is highlighting some of the lessons scientists have learned about aquatic invasive species, including that far more ecosystems are playing host to non-native species than previously thought. 聽However, the researchers note, those species aren鈥檛 necessarily detrimental to their new habitat and, in some cases, the negative 鈥渋mpacts of invasive species control may be greater than the impacts of the invasive species鈥� themselves.

As they are in many places around the globe, glaciers perched high in the Andes Mountains are shrinking. Now, researchers at the University of Wisconsin鈥揗adison and their collaborators have uncovered evidence that the high-altitude tropical ice fields are likely smaller than they鈥檝e been at any time since the last ice age ended 11,700 years ago.

An invasive fungus that colonizes the skin of hibernating bats with deadly consequences is a stealthy invader that uses multiple strategies to slip into the small mammals' skin cells and quietly manipulate them to aid its own survival. The fungus, which causes the disease white-nose syndrome, has devastated several North American species over the last 18 years.

In a rare opportunity to study carnivores before and after wolves were reintroduced to their ranges, researchers from the University of Wisconsin鈥揗adison found that the effects of wolves on Isle Royale have been only temporary. And even in the least-visited national park, humans had a more significant impact on carnivores鈥� lives.

The small footprint and dim light of white dwarfs, remnants of stars that have burned through their fuel, may make excellent backdrops for studying planets with enough water to harbor life. The trick is spotting the shadow of a planet against a former star that has withered to a fraction of its size and finding that it鈥檚 a planet that has kept its water oceans for billions of years even after riding out the star鈥檚 explosive and violent final throes.

Clouds of gas in a distant galaxy are being pushed faster and faster 鈥� at more than 10,000 miles per second 鈥� out among neighboring stars by blasts of radiation from the supermassive black hole at the galaxy鈥檚 center. It鈥檚 a discovery that helps illuminate the way active black holes can continuously shape their galaxies by spurring on or snuffing out the development of new stars.

Farmland is often a battleground in the fight against climate change.Solar panels and energy crops are pitted against food production, while well-intended policy choices can create incentives for farmers to till up new lands, releasing even more heat-trapping gas into the atmosphere.That鈥檚 why strategies for sustainable plant-based fuels focus on marginal lands 鈥� fields that are too hard to cultivate or don鈥檛 produce good enough yields to be considered profitable.

Consuming raw cow's milk that contains H5N1 avian influenza virus poses an infection risk, but a laboratory process that simulates high-temperature pasteurization reduces the virus in infected milk by more than 99.99%. That's according to a team led by University of Wisconsin鈥揗adison scientists, who reported their findings May 24 in a letter published in the New England Journal of Medicine.

Many pancreatic tumors are like malignant fortresses, surrounded by a dense matrix of collagen and other tissue that shields them from immune cells and immunotherapies that have been effective in treating other cancers. Employing bacteria to infiltrate that cancerous fortification and deliver these drugs could aid treatment for pancreatic cancer, according to newly published findings from a team of University of Wisconsin鈥揗adison researchers.
