Scientists have long known that light can sometimes appear to exit a material before entering it—an effect dismissed as an illusion caused by how waves are distorted by matter.
Phys.org / The genomic journey of modern and archaic humans may be older than we thought
Research conducted at the Department of Biology, University of Padova, has identified critical genomic milestones in the evolution of Homo sapiens, including key chromosomal rearrangements and specific gene variants that ...

Medical Xpress / Salt-seeking behavior traced to specific brain neurons
Salt, or more precisely the sodium it contains, is very much a "Goldilocks" nutrient. Low sodium levels cause a drop in blood volume, which can have serious, sometimes deadly, health consequences. Conversely, too much salt ...
Medical Xpress / Microscopic cell changes linked to cancer's rapid growth in stiff tissues
In 2022 alone, over 20 million people were diagnosed with cancer, and nearly 10 million died from the disease, according to the World Health Organization. While the reaches of cancer are massive, the answer to more effective ...
