Climate change pushing up levels of methylmercury in fish

A new study concludes that while the regulation of mercury emissions have successfully reduced methylmercury levels in fish, spiking temperatures are driving those levels back up and will play a major role in the methylmercury levels of marine life in the future.

Harvard study reveals ancient Mesoamericans’ knowledge about Earth’s magnetism

Led by Assistant Professor of Earth and Planetary Sciences Roger Fu, a team of researchers has shown that the makers of ancient Mesoamerican statues found in Guatemala intentionally carved the figures to place the magnetic areas over the navel or right temple — suggesting not only that they were familiar with the concept of magnetism, but had some way of detecting the magnetic anomalies.

Wyss researchers has electrifying insights into how bodies form

A researcher is reviving the study of bioelectricity to learn how cells communicate with each other to form tissues and organs, and how harnessing those signals could one day lead to truly regenerative medicine, in which amputees could simply regrow limbs.
