Our colleague, professor Mykhailo Kozlovskii, the well-known Ukrainian scientist in field of phase transitions and critical phenomena, turns 70 on August 30, 2022. The approach for treating behaviour three-dimensional systems, initiated by academician Ihor Yukhnovskii further developed M. forms a new direction transition theory.

A strange but interesting paper [2] by scientists at The University of Wisconsin, which just appeared in PNAS, examines whether two similar sunscreen chemicals, homosalate and octisalate, could be a possible treatment for multiple sclerosis (MS). (See my colleague Julianna LeMieux's companion article "Sunscreen, MS And A Scientific Finding That Is Hard To Believe [3]" about the biological activ...

The development of mathematical insight, the knack for discovering novel solutions to mathematical problems, might be one of the most erudite forms of learning that we can hope to achieve. However, Wagner and his colleague now report that a night of sleep after being exposed to a class of mathematical problems more than doubles the likelihood of discovering just such a novel solution.

In a collaborative research initiative, investigators from Dr. Hubank’s laboratory and those from the lab of his colleague Jonathan Ham, M.D., compared the genomic profiles of samples from pediatric medulloblastoma patients with those from normal cerebellar tissues by using Affymetrix Exon arrays. They reported that different splicing patterns exist between the two groups and between different ...
