Visualizing how flutter kick vertical vortices generate propulsion and suppress body sway in swimmers

Transposons, DNA sequences that can self-replicate and move (jump) throughout the genome, are widespread and can affect cell survival if left unchecked. Cells control these "jumping genes" by silencing them, but little was known about how cells recognize and defend themselves from invading transposons.

Increasingly, the world's oceans are telling us our climate system may be changing faster and more dramatically than expected.

Carbon dioxide (CO2) separation is central to technologies ranging from natural gas purification to hydrogen production and carbon management. One widely used approach relies on thin filtering materials called membranes. However, these membranes face a major challenge: materials that allow CO2 to pass through quickly are often less effective at separating it from other gases, while highly selective materials usually slow the flow of CO2. This balancing act is known as the permeability-selectivit

A new Physical Review Letters study places constraints on the ER = EPR conjecture, showing that under the authors' assumptions, the conjecture would imply possible alterations to the hyperfine structure and effective charge of the hydrogen atom—effects that have never been observed.
