A safer heart pump is important for patients with serious heart disease because they are commonly used as a bridge-to-transplant for patients waiting for a heart. The less time on a heart pump, the better, given the stroke and blood clot risk

Building a safer heart pump

The heart pumps, also known as a ventricular assist device to support heart function and blood flow in people who have weakened hearts. The...

Optimizing technologies to detect cancer cell mutations

Cancer cells frequently have transformations in their DNA that can give researchers hints about how the tumor began or which treatment might be best....
Artist's conception of a planet covered with a global ocean. A new study finds that these water worlds could maintain stable climates and perhaps sustain life

Water world planets could have stable climate, perhaps support life, study

According to a new study by the University of Chicago and Penn State, planets with water worlds could maintain surface conditions as like as...
Adolescent students in a rural school in India who consumed an iron-biofortified version of the grain pearl millet exhibited improved attention and memory compared to those who consumed conventional pearl millet, according to Penn State researchers. Image: Getty images monkeybusinessimages

Consuming iron-fortified grain improves students’ attention, memory

Iron deficiency remains the most prevalent micronutrient deficiency globally, but few studies have examined how iron status relates to cognition in adolescents. Benefits of consuming...
morning stress

Expecting a stressful day may lower cognitive abilities throughout the day

According to Penn State researchers, there may be some truth to the saying "getting up on the wrong side of the bed". A new...

The MXene nanosheets are distributed homogeneously along the ZnO grain boundaries, as seen in the TEM image and EDS map. Image: MRI/Penn State

Sintering atomically thin materials with ceramics now possible

Sintering is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of...
"The changes in the microbiota might affect how much vitamin D a person can metabolize, or how the body metabolizes vitamin D, so there are implications, but it's still early and that remains to be seen," said Cantorna.

Gut microbes may link with a protein to help regulate vitamin D

An accumulation of bacteria in the gut may utilize a cell signaling protein to help manage vitamin D, a key supplement that, among different...
The scientists developed a novel high-throughput sequencing technique that efficiently detected in bees both previously identified and 27 never-seen-before viruses belonging to at least six new families in a single experiment. Image: Jeff Kerby / National Geographic

Scientists discovered evidence of 27 new viruses in bees

Populations of bees around the world are declining. According to scientists, viruses are the fundamental cause behind this. Now, a team of scientists at...
Posttraumatic stress disorder (PTSD) caused by traumatic military experiences is associated with feelings of anxiety, anger, sadness and/or guilt. New Penn State research is evaluating how PTSD symptoms increase risks for academic difficulties as well. Image: Katarzyna Białasiewicz

Posttraumatic stress affects academics

A new study by the Penn State which evaluates what causes the risk of Posttraumatic stress disorder (PTSD) found that this traumatic military experience...
