In a comprehensive and complex molecular study of blood samples from Ebola patients in Sierra Leone, published today (Nov. 16, 2017) in Cell Host and Microbe, a scientific team led by the University of Wisconsin–Madison has identified signatures of Ebola virus disease that may aid in future treatment efforts.

Molecular Magnetism Packs Power with “Messenger Electron”

A UW–Madison lab has made a molecule that gains magnetic strength through an unusual way of controlling those spins, which could lead to a breakthrough in quantam computing.

Breeding Highly Productive Corn Has Reduced Its Ability to Adapt

Natalia-1024x683.jpg

Researchers at the University of Wisconsin–Madison wanted to know whether the last 100 years of selecting for corn that is acclimated to particular locations has changed its ability to adapt to new or stressful environments. By measuring populations of corn plants planted across North America, they could test how the corn genomes responded to different growing conditions.

UW Scientists Create a Recipe to Make Human Blood-Brain-Barrier

In a report published this week (Nov. 8, 2017) in Science Advances, researchers from the University of Wisconsin-Madison detail a defined, step-by-step process to make a more exact mimic of the human blood-brain-barrier in the laboratory dish. The new model will permit more robust exploration of the cells, their properties and how scientists might circumvent the barrier for therapeutic purposes.

New Model Reveals Possibility of Pumping Antibiotics Into Bacteria

Researchers in the University of Wisconsin–Madison Department of Biochemistry have discovered that a cellular pump known to move drugs like antibiotics out of E. coli bacteria has the potential to bring them in as well, opening new lines of research into combating the bacteria.

Cool Idea: Magma Held in ‘Cold Storage’ Before Giant Volcano Eruption

Long Valley, California, has long defined the “super-eruption.” About 765,000 years ago, a pool of molten rock exploded into the sky. Within one nightmarish week, 760 cubic kilometers of lava and ash spewed out in the kind of volcanic cataclysm we hope never to witness. A new study shows that the giant body of magma — molten rock — at Long Valley was much cooler before the eruption than previously thought.

A Little Myelin Goes a Long Way to Restore Nervous System Function

A team of researchers from the University of Wisconsin-Madison reports that in long-lived animals, renewed but thin myelin sheaths are enough to restore the impaired nervous system and can do so for years after the onset of disease.

New Study Shows How Cells Can Be Led Down Non-Cancer Path

As cells with a propensity for cancer break down food for energy, they reach a fork in the road: They can either continue energy production as healthy cells, or shift to the energy production profile of cancer cells. In a new study, University of Wisconsin–Madison researchers map out the molecular events that direct cells’ energy metabolism down the cancerous path. Their findings could lead to ways to interrupt the process.

H7N9 Influenza Is Both Lethal and Transmissible in Animal Model for Flu

In 2013, an influenza virus began circulating among poultry in China. It caused several waves of human infection and as of late July 2017, nearly 1,600 people had tested positive for avian H7N9. Nearly 40 percent of those infected had died. In 2017, Yoshihiro Kawaoka of the University of Wisconsin-Madison received a sample of H7N9 virus isolated from a patient in China who had died of the flu. He and his research team subsequently began work to characterize and understand it.

Autism Prevalence and Socioeconomic Status: What’s the Connection?

Children living in neighborhoods where incomes are low and fewer adults have bachelor’s degrees are less likely to be diagnosed with autism spectrum disorder compared to kids from more affluent neighborhoods.
