Scientists have created an elaborate map of more than a billion brain cell connections, helping to shed light on how memories are formed and recalled. Their complex series of images are the first to illustrate how these vital connections are... Continue Reading →
The Bekenstein-Hawking entropy or black hole entropy is the amount of entropy that must be assigned to a black hole in order for it to comply with the laws of thermodynamics as they are interpreted by observers external to that black hole. This is particularly true for the... Continue Reading →
What is Reynolds number?The Reynolds number is an important dimensionless quantity in fluid mechanics used to help predict flow patterns in different fluid flow situations. Magmas typically consist of a mixture of molten liquid, bubbles, and solid crystals. As they... Continue Reading →
Scientists, using an instrument aboard NASA’s Lunar Reconnaissance Orbiter (LRO), have observed water molecules moving around the dayside of the Moon. A paper published in Geophysical Research Letters describes how Lyman Alpha Mapping Project (LAMP) measurements of the sparse layer... Continue Reading →
Columbia engineers and neuroscientists have joined forces to create 3D videos of individual nerve cells moving, stretching and switching on inside fruit fly larvae as they move. Data gleaned from these videos reveals how nerve cells called proprioceptive neurons work... Continue Reading →
This week NASA released the first-ever image of shock waves interacting between two supersonic aircraft. It’s a stunning effort, requiring a cutting-edge version of a century-old photographic technique and perfect coordination between three airplanes – the two supersonic Air Force T-38s and the NASA B-200 King...

Studies of health effects of alcohol consumption may underestimate the risks of imbibing, particularly for younger people, according to a new study in the Journal of Studies on Alcohol and Drugs. The research demonstrates that although cohort studies--the type of observational... Continue Reading →
On January 1, New Horizons swooped to within 3,500 kilometers of the Kuiper Belt world known as Ultima Thule. That's about 3 times closer than its July 2015 closest approach to Pluto. The spacecraft's unprecedented feat of navigational precision, supported by... Continue Reading →
Results from a pioneering clinical trials programme that delivered an experimental treatment directly to the brain offer hope that it may be possible to restore the cells damaged in Parkinson's. The multimillion-pound study, funded by Parkinson's UK with support from... Continue Reading →
