New research tries to explain consciousness with… quantum physics This research could either confirm or dismiss Penrose and Hameroff’s controversial theory Brains and fractals Our brains are composed of cells called neurons, and their combined activity is believed to generate consciousness. Each neuron containsmicrotubules, which transport substances to different parts of the cell. The Penrose-Hameroff theory of quantum consciousness argues that microtubules are structured in afractal patternwhich would enable quantum processes to occur....

New satellite tech could reveal the cause of the rare milky seas So milky and mysterious Sailors’ tales To date, only one research vesselhas ever encountered a milky sea.That crew collected samples and found a strain of luminous bacteria calledVibrio harveyicolonizing algae at the water’s surface. Unlike bioluminescence that happens close to shore, where small organisms called dinoflagellates flash brilliantly when disturbed, luminous bacteria work in an entirely different way. Once their population gets large enough – about 100 million individual cells per milliliter of water – a sort ofinternal biological switch is flippedand they all start glowing steadily....

New study offers clues about how Mars lost its water Its small size and low gravity have caused Mars to lose most of its atmosphere Water escapes from the Martian atmosphere The evidence suggests that Mars was not always the cold, arid planet we observe today. There is plenty of evidence of water on Mars’s surface in the distant past – about four billion years ago. At that time, liquid water flowed in great streams and stagnated in the form of pools or lakes, such as in the Jezero crater explored by the Perseverance rover, in search of traces of past life....
