“A healthy person is going to be able to withstand an illness from the outside better than an unhealthy person,” says Justin Ries, a professor of marine and environmental science. “It’s the same thing with an ecosystem.”

To predict our future climate, they’re digging into the mud of the past

Using molecules left in the mud of an Illinois lakebed by long-dead bacteria, Samuel Muñoz, an assistant professor of marine and environmental sciences, and his colleagues have reconstructed ancient climate conditions in the midwestern United States. Their results could help us anticipate what’s in store for our future as the planet continues to warm.

The new fitness coach might not have a body

A group of researchers led by Timothy Bickmore, a professor of computer sciences at Northeastern, has designed a digital, bilingual coach to help older Latino adults meet their fitness goals. In a year-long study, the virtual advisor, Carmen, performed just as well as her human counterparts.

Flu season is coming and COVID-19 is still here. Can disease forecasts tell them apart?

Both viruses attack the respiratory system and can have similar symptoms. “Something like this is completely unprecedented,” says Alessandro Vespignani, who directs Northeastern’s Network Science Institute. “Having a major pandemic and then trying to get insight on the seasonal flu—it’s a completely new game.”

Why does COVID-19 hit hard and fast in some places, but not others?

“The way populations are structured matters quite a bit in terms of the potential risk for sharp, intense epidemics, as compared to broader, slower-burning epidemics,” says Samuel Scarpino, an assistant professor in Northeastern’s Network Science Institute.

What do we know about airborne transmission of the coronavirus?

Last week, the Centers for Disease Control and Prevention posted—and then quickly removed—new guidelines indicating that the coronavirus is airborne, leaving people confused about vital public information. Samuel Scarpino, assistant professor and head of the Emergent Epidemics Lab, explains where the science stands.

How do you learn hands-on medical skills during a pandemic?

Clad in masks, face shields, and gloves, a dozen students in Northeastern's physician assistant program begin to pore over each other’s hands, arms, neck, and scalp. Six more students begin the same process without all the protective equipment; their patients are family members, friends, and partners, and their exam spaces are living rooms, bedrooms, and home offices.

Just how much contact tracing and testing do we need?

How much testing is enough? What percentage of people who’ve been unwittingly exposed to the virus do we need to track down? How many people will need to be quarantined? In a recent study published in Nature Human Behaviour, researchers in Northeastern’s Network Science Institute sought to quantify these answers.

Hybrid NUflex is ready for the fall semester. Are you?

Welcome to the Hybrid NUflex classroom: Eight cupcake-shaped microphones extend from the ceiling like futuristic stalactites. Two swiveling cameras flank the clock at the front of the room. A single camera at the back focuses its lens on the instructor, blackboard, and projection screen. Northeastern is ready for hybrid learning.
