Tiny robots, big impact: Revolutionizing infertility treatment with magnetic microrobots

Infertility affects an estimated 186 million people worldwide, with fallopian tube obstruction contributing to 11%-67% of female infertility cases. Researchers have developed an innovative solution using a magnetically driven robotic microscrew to treat fallopian tube blockages. The microrobot is made from nonmagnetic photosensitive resin, coated with a thin iron layer to give it magnetic properties. By applying an external magnetic field, the robot rotates, generating translational motion that enables it to navigate through a glass channel simulating a fallopian tube.

The Death of Russia’s Chemical Weapons Chief: A Turning Point in Ukraine’s Unconventional Warfare

Unveiling the Strategy The assassination of Lieutenant-General Igor Kirillov, Russia’s head of nuclear, biological, and chemical defense forces, marks a dramatic escalation in Ukraine’s unconventional warfare against Moscow. By targeting a top military figure accused of orchestrating chemical attacks, Ukraine signals its readiness to strike at the heart of Russian leadership. This development raises significant...
