Treatment reverses paralysis in mice; offers a general delivery platform for neurologic drugs. Currently there’s no treatment for botulism once the toxin gets into neurons...

Engineers demonstrate a new shape-changing nozzle that could revolutionize ‘4D printing’ applications. Engineers at the University of Maryland (UMD) have created a new shape-changing or “morphing” 3D printing nozzle that was featured as a Frontispiece in the January 5th issue of the journal Advanced Materials Technologies.

The team’s morphing nozzle offers researchers new means for 3D printing “fiber-filled composites” — materials made up of short fibers that boost special properties over traditional 3D-printed parts, such as enhancing part strength or electrical conductivity. The challenge is that these properties are based on the directions or “orientations” of the short fibers, which has been difficult to control during the 3D printing process, until now.

“When 3D printing wi...

In 2020, astronomers added a new member to an exclusive family of exotic objects with the discovery of a magnetar. New observations from NASA’s Chandra X-ray Observatory help support the idea that it is also a pulsar, meaning it emits regular pulses of light.

Magnetars are a type of neutron star, an incredibly dense object mainly made up of tightly packed neutron, which forms from the collapsed core of a massive star during a supernova.

What sets magnetars apart from other neutron stars is that they also have the most powerful known magnetic fields in the universe. For context, the strength of our planet’s magnetic field has a value of about one Gauss, while a refrigerator magnet measures about 100 Gauss...

In a study to examine a Mediterranean diet in relation to prostate cancer progression in men on active surveillance, researchers from The University of Texas MD Anderson Cancer Center found that men with localized prostate cancer who reported a baseline dietary pattern that more closely follows the key principles of a Mediterranean-style diet fared better over the course of their disease.

“Men with prostate cancer are motivated to find a way to impact the advancement of their disease and improve their quality of life,” said Justin Gregg, M.D., assistant professor of Urology and lead author of the study, published today in Cancer. “A Mediterranean diet is non-invasive, good for overall health and, as shown by this study, has the potential to effect the progression of their cancer.”
