Newly identified cellular trash removal program helps create new neurons

MADISON — New research by University of Wisconsin-Madison scientists reveals how a cellular filament helps neural stem cells clear damaged and clumped proteins, an important step in eventually producing new neurons. The work provides a new cellular target for interventions that could boost neuron production when it’s needed most, such as after brain injuries. And…

Could new discovery play a role in diagnosing Alzheimer’s earlier?

Scientists have detected that a previously overlooked gene behavior could potentially lead to a new way to diagnose Alzheimer’s earlier. Published in the journal Epigenetics, an international research team’s findings — discovered in mice and confirmed in human samples — suggest that the gene Presenilin1 (PSEN1) should be monitored as a ‘biomarker’: to see what…

How door-to-door canvassing slowed an epidemic

Liberia was the epicenter of a high-profile Ebola outbreak in 2014-15, which led to more than 10,000 deaths in West Africa. But for all the devastation the illness caused, it could have been worse without an innovative, volunteer-based outreach program Liberia’s government deployed in late 2014. Now, a study co-authored by an MIT professor shows…

Getting off of the blood sugar roller coaster

For the 250,000 Canadians living with type 1 diabetes, the days of desperately trying to keep their blood sugar stable are coming to an end. A team of researchers at McGill University’s Faculty of Medicine is working to optimize an artificial pancreas with the ability to minimize the glucose highs and lows that diminish quality…

New algorithm tracks pediatric sepsis epidemiology using clinical data

Philadelphia, February 27, 2020—Researchers at Children’s Hospital of Philadelphia (CHOP) have developed a novel computational algorithm to track the epidemiology of pediatric sepsis, allowing for the collection of more accurate data about outcomes and incidence of the condition over time, which is essential to the improvement of care. The tool was described in a paper…

Lessons learned from addressing myths about Zika and yellow fever outbreaks in Brazil

When disease epidemics and outbreaks occur, conspiracy theories often emerge that compete with the information provided by public health officials. A Dartmouth-led study in Science Advances finds that information used to counter myths about Zika in Brazil not only failed to reduce misperceptions but also reduced the accuracy of people’s other beliefs about the disease.…

Wine glass size may influence how much you drink in restaurants

The size of glass used for serving wine can influence the amount of wine drunk, suggests new research from the University of Cambridge, funded by the National Institute of Health Research (NIHR). The study found that when restaurants served wine in 370ml rather than 300ml glasses they sold more wine, and tended to sell less…

They Were Infected With the Coronavirus. They Never Showed Signs.

In Anyang, China, five members of a family came down with the coronavirus after hosting a guest from Wuhan in early January. But the visitor, a 20-year-old woman, never got sick herself. Some individuals who are infected with the coronavirus can spread it even though they have no symptoms, studies have shown. Asymptomatic carriers are…
