The problem is that the origin of the hybrid yeast used in lager beer is relatively unknown. We know that a domesticated yeast (Saccharomyces cerevisiae) combined with a recently discovered yeast (Saccharomyces eubayanus) at some point to create an interspecies hybrid — but we’ve never understood how the two halves met.
Research has shown that approximately two-thirds of the population have experienced some form of childhood adversity by the age of 18. So why do so many people emerge from difficult childhoods seemingly unscathed, while others develop various forms of mental illness? And are there any evident brain differences between the two types?
Five-year-old Naja Tunney’s home is filled with books. Sometimes, she’ll pull them from a bookshelf to read during meals. At bedtime, Naja reads to her 2-year-old sister, Hannah.
Family stressors can take a toll on children and approximately two-thirds of youth will experience some form of childhood adversity by the age of 18. Research has primarily focused on how adversity at a young age can lead to mood disorders in adolescence, but most children exhibit resilience to adverse experiences. So senior author Dr. Marilyn Essex, Professor of Psychiatry at the University of Wisconsin, and colleagues followed 132 kids from infancy to 18 years old to search for a neurobiological mechanism of emotional adaptation.

Researchers at the University of Wisconsin-Madison have confirmed a type of bacteria can completely block the transmission of the Zika virus.
Researchers at the University of Wisconsin-Madison said Friday they have taken a step toward blocking transmission of the Zika virus.
A bacteria found in butterflies and bees can help prevent the spread of Zika virus, suggesting that mosquitoes could be infected with the bacteria and released into the wild to control Zika outbreaks, UW-Madison researchers said Friday.
Barbara Wolfe and Jason Fletcher at the University of Wisconsin-Madison found children from lower income families have lower non-cognitive skills than children from richer families.
New experiments have shown that one infection with Zika virus can provide immunity against subsequent exposure to the virus, a piece of good news published Tuesday as officials continue to wrestle with the mosquito-borne threat.
Fred Lee is not afraid to put himself out there. Lee is a radiologist at the University of Wisconsin Hospital and Clinics, where his primary area of interest is the ablation, or elimination, of cancerous tumors. He says that around the year 2000, he decided that the radio frequency ablation devices he and his colleagues were using “were just not good enough.” But since Lee’s background wasn’t in engineering, he had to reach out for help.
Monkeys infected with Zika virus are protected from future infection, and pregnancy dramatically prolongs infection in monkeys, findings that could help fight the virus in people, UW-Madison researchers said Tuesday.
Dawn Dudley, a research scientist at UW-Madison’s School of Veterinary Medicine and Medicine and Public Health talks about the fight against the Zika virus and a real-time look at their research findings.
The Zika Virus has been a major concern among public health officials and world leaders in recent months, especially now that the Summer Olympic Games in Brazil are just a few short weeks away.
Scientists have developed a nonhuman primate model of Zika virus infection to better understand its course in humans, especially in pregnant women. David O’Connor of the University of Wisconsin-Madison and colleagues injected eight rhesus macaques—two of them pregnant—with the Asian strain of the virus currently circulating in South and Central America. The non-pregnant and pregnant monkeys were still infected 21 days and up to 57 days later, respectively, and all animals were immune to reinfection 10 weeks post-injection, the researchers reported today (June 28) in Nature Communications. Prior to publication, the team was posting its data online in real time.
New research on monkeys found some good news that could have implications for humans: One infection with the Zika virus protects against future infections.
Scientists have successfully infected a group of rhesus macaque monkeys with Zika, marking the first time that non-human primates have been shown to be susceptible to the mosquito-borne virus. That’s good news for researchers, as it potentially opens up a new animal model to study Zika. Scientists could use the monkeys to trace how the virus spreads and test new vaccines or treatments on the animals.
A new animal study adds to the complexity of Zika infection during pregnancy
Infection with the Zika virus may protect against future infection, but pregnancy seems to extend how long the mosquito-borne virus stays in the body, a new study in monkeys suggests.
A batch of new studies show the Zika virus is trickier than it appeared at first glance, lurking for months in pregnant females and interfering with the immune system’s response.
University of Wisconsin-Madison researchers have found that a single exposure to the Zika virus protected monkeys against a second bout of the infection. That natural immunity may help in work to develop a vaccine.
Rhesus macaque monkeys make a good model for studying how Zika infects people, researchers at the University of Wisconsin-Madison concluded Tuesday in Nature Communications.
“A sustained [Zika] infection during pregnancy is completely different from a normal infection,” study senior author David O’Connor of the University of Wisconsin, Madison, told BuzzFeed News. The monkey results make sense, he said, given that other research has shown that the virus prefers the fetal brain and placenta over other tissue types.
In another advance, researchers at the University of Wisconsin reported on Tuesday that they have successfully infected rhesus macaques with an Asian strain of the Zika virus that is currently circulating in the Americas. The study, published in the journal Nature Communications, shows that monkeys – which have immune responses similar to humans – can be used to study Zika.

Researchers at the University of Wisconsin at Madison and Duke University found the virus persisted in the blood of pregnant monkeys for much longer — up to 70 days — compared to the 10 days it lasted in males and non-pregnant female monkeys.
The University of Wisconsin-Madison researchers say this is good news for vaccine developers. Lead researcher Prof David O’Connor said: “It suggests the sort of immunity that occurs naturally is sufficient. If you can mimic that in a vaccine, you’ll likely have a very successful vaccine.”

Despite an increase in jobs, there was no reduction in poverty in Wisconsin between 2013 and 2014 under a broad measure developed by researchers at the University of Wisconsin.
This week’s challenge was suggested by Jordan Ellenberg, a math-world superstar and current professor of mathematics at the University of Wisconsin. Jordan is the child prodigy who turned out well. After teaching himself to read at age 2, he attained a perfect 800 on the math portion of the SAT at age 12, won two gold medals in the International Math Olympiad (with perfect scores), and was a two-time Putnam Fellow at Harvard.
Walk into most macaque enclosures, and you might expect a ruckus: bird-like cooing if you’re bringing them food, or guttural barks if you aren’t.
The Rising Star cave system, part of the Cradle of Humankind World Heritage Site in South Africa, has been well mapped and was explored by cavers for many years, but without any fossils being noted there. That changed in September 2013, when two South African cavers, Rick Hunter and Steve Tucker, entered a remote, unmapped chamber and found the first-known fossil bones of what is now called Homo naledi strewn across its floor.
A UW-Madison virologist whose controversial work has sought to create more effective flu vaccines will receive a prestigious award from Japan’s scientific academy, officials announced Wednesday.
There’s an arms race raging underground – well, between microbes and plants anyway. When bacteria attack crop roots, plants fight back by snaring the pathogens in a sticky trap made from their own DNA secretions. But a new study shows how the bacteria bust out, using a set of enzymes that act as molecular scissors, splitting the DNA like bubble wrap.

Wisconsin consumers widely agree that “local” food means food grown in Wisconsin, according to a new statewide survey conducted by faculty affiliated with the University of Wisconsin-Extension, UW-Madison, and UW-River Falls. Food from Michigan, Iowa, Illinois, and Minnesota, meanwhile, is not considered “local” by most Wisconsin shoppers.
Data collected from sensors on a buoy in Lake Mendota map the ebb and flow of the algal blooms that each year turn the lake green with phytoplankton. A look at the patterns created over time shows a confluence of interconnected cycles driven by season, temperature, sunrise and sunset.
iPS cells have made their mark in a different way. They have become an important tool for modelling and investigating human diseases, as well as for screening drugs. Improved ways of making the cells, along with gene-editing technologies, have turned iPS cells into a lab workhorse — providing an unlimited supply of once-inaccessible human tissues for research. This has been especially valuable in the fields of human development and neurological diseases, says Guo-li Ming, a neuroscientist at Johns Hopkins University in Baltimore, Maryland, who has been using iPS cells since 2006.
Since the 17th century, when Antonie van Leeuwenhoek first observed microorganisms through the lens of a rudimentary microscope, humans have slowly come to appreciate that ours is a germy world.
The remnants of this town, nestled along a shallow bend in the Crawfish River, have generated many other fantastic myths over time — myths that researchers like University of Wisconsin-Madison anthropology professor Sissel Schroeder work to dispel.
Snapshot Wisconsin, as the project has been named, is “an unprecedented effort to capture in space and time the deer, bears, elk, coyotes, bobcats, badgers, and any other wild animal that lumbers, hops, lopes or slithers across the Badger state,” according to the University of Wisconsin-Madison, the school leading the charge on this project. “Snapshot Wisconsin aims to provide one of the richest and most comprehensive caches of wildlife data for any spot on our planet.”
Like some humans, giant pandas struggle with digestion due to changes in diet – an affliction that could be interrupting their reproduction, according to a new study.
AZTALAN — Ancient Aztalan was a prehistoric Native American village in southern Wisconsin occupied by Mississippian and Late Woodland peoples 800 to 1,000 years ago. Archaeological evidence suggests it was an ethnically diverse community — some residents were local to the area, but others were newcomers who brought their exotic beliefs, practices and ways of living with them.
