Approximately 1.5 million heart attacks and strokes occur every year in men and women in the U.S. Sex and age play a large part in who experiences a heart attack, the methods used to treat these heart attacks, and the eventual post hospital outcomes of the people who experience heart attacks.

Appearance, social norms keep students off Zoom cameras
Cornell researchers surveyed the 312 students in the class at the end of the semester to figure out why they weren’t using their cameras – and to try to come up with ways to turn that trend around. They found that while some students had concerns about the lack of privacy or their home environment, 41% of the 276 respondents cited their appearance, and more than half of those who selected “other” as their reason for keeping their camera off explained that it was the norm. This suggested that explicitly encouraging camera use could boost participation without adverse effects, the researchers said.

Fastener with Microscopic Mushroom Design Holds Promise
A Velcro-like fastener with a microscopic design that looks like tiny mushrooms could mean advances for everyday consumers and scientific fields.

The team believes a 3D mushroom design can be made with softer, more flexible materials and provide sufficient interlocking force on the fabric and hold strong.

Eggs Reveal What May Happen to Brain on Impact
Our brains consist of soft matter bathed in watery cerebrospinal fluid inside a hard skull, and in Physics of Fluids, researchers describe studying another system with the same features, an egg, to search for answers about concussions. Considering that in most concussive brain injuries, the skull does not break, they wanted to find out if it was possible to break or deform the egg yolk without breaking the eggshell and did a simple experiment using an egg scrambler, measuring the soft matter deformation.
DNA Origami Enables Fabricating Superconducting Nanowires
In AIP Advances, researchers describe how to exploit DNA origami as a platform to build superconducting nanoarchitectures.
