The paradox that moves against the rules: Researchers from Ariel University cracked a 120-year-old engineering puzzle

Prof. Nir Schwalb and Dr. Oded Medina showed that not only the number of links and axes determines the movement in the mechanism, but also their geometric arrangement in space, and they also discovered "hypo-paradoxical" mechanisms that lock even though, according to

New study: Ancient magnetic fields may explain the difference between Jupiter's moons and Saturn's moons

Simulations by researchers from Japan and China suggest that Jupiter's strong magnetic field created a void in the disk around it and preserved large moons, while at Saturn a weaker field led to a more sparse system dominated by

Do Corona Vaccines Increase Cancer Risk? The Korean Study That Claimed This Did Not Prove a Causal Link

A new study supposedly found a link between coronavirus vaccines and an increased risk of cancer. In fact, the study has fundamental flaws and does not prove causation – and other studies have not found such a link.
