The Times and Troubles of the Scientific Method

UPDATE: We got a couple of things wrong when it comes to gravity (particularly that it has nothing to do with photons). Check out this video from TheGentlemanPhysicis (http://www.youtube.com/watch?v=4y-dFLZHb1c) in which our confusion is explained. We also did a whole video about gravitation in our series on the four fundamental forces of physics, which you […]

Kicking neural network automation into high gear — ScienceDaily

A new area in artificial intelligence involves using algorithms to automatically design machine-learning systems known as neural networks, which are more accurate and efficient than those developed by human engineers. But this so-called neural architecture search (NAS) technique is computationally expensive. One of the state-of-the-art NAS algorithms recently developed by Google took 48,000 hours of […]

Philosophers and neuroscientists join forces to see whether science can solve the mystery of free will | Science

A new research program on free will teams up neuroscientists and philosophers. iStock.com/rudall30 By Bahar GholipourMar. 21, 2019 , 11:05 AM Philosophers have spent millennia debating whether we have free will, without reaching a conclusive answer. Neuroscientists optimistically entered the field in the 1980s, armed with tools they were confident could reveal the origin of […]

Clever math enables MRI to map molecules implicated in multiple sclerosis, other diseases | Science

A noisy map of myelin in the brain (left) becomes more stable and sensitive (right) thanks to a new mathematical technique. M. BOUHRARA ET AL., NEUROIMAGE, 127, 456 (2016) By Adrian ChoMar. 20, 2019 , 10:55 AM BOSTON—MRI scanners can map a person’s innards in exquisite detail, but they say little about composition. Now, physicists […]

Evidence for a Human Geomagnetic Sense — ScienceDaily

Scientists develop a robust experiment that shows human brain waves respond to changes in Earth-strength magnetic fields. Many humans are able to unconsciously detect changes in Earth-strength magnetic fields, according to scientists at Caltech and the University of Tokyo. The study, led by geoscientist Joseph Kirschvink (BS, MS ’75) and neuroscientist Shin Shimojo at Caltech […]
