Swarms of ‘ant-like’ robots lift heavy objects and hurl themselves over obstacles

Scientists have developed swarms of tiny magnetic robots that work together like ants to achieve Herculean feats, including traversing and picking up objects many times their size. The findings suggest that these microrobot swarms -- operating under a rotating magnetic field -- could be used to take on difficult tasks in challenging environments that individual robots would struggle to handle, such as offering a minimally invasive treatment for clogged arteries and precisely guiding organisms.

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...
