US Navy is Liable for Mass Software Piracy, Appeals Court Rules
The United States Navy is liable for a mass copyright infringement. The Court of Appeals for the Federal Circuit sided with the German software company Bitmanagement, which accused the Navy of copying software without permission. Bitmanagement claimed more than $500 million in damages, but the final amount has yet to be determined. From a report: The dispute started when the US…
We may have to rewrite our understanding of gravity
There is a mismatch between two ways of measuring galactic mass. Dark matter is one way to solve it, but so is rewriting the laws of gravity, says Chanda Prescod-Weinstein Source: https://www.newscientist.com/article/mg24933240-100-we-may-have-to-rewrite-our-understanding-of-gravity/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

The hidden rules that determine which friendships matter to us
Evolutionary psychologist Robin Dunbar has found that our friendships are governed by secret rules, based on everything from your sex to your sleep schedule. Our unique social fingerprints help determine who we are drawn to, which friendships last and why some friends are ultimately replaceable Source: https://www.newscientist.com/article/mg24933240-700-the-hidden-rules-that-determine-which-friendships-matter-to-us/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
A warp drive that doesn’t break the laws of physics is possible
Previous ideas for warp drives have required types of matter that do not seem to exist, but a new concept could allow them to be made without any imaginary substances Source: https://www.newscientist.com/article/2269544-a-warp-drive-that-doesnt-break-the-laws-of-physics-is-possible/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Photon-photon polaritons: the intriguing particles that emerge when two photons couple
Scientists at the University of Bath in the UK have found a way to bind together two photons of different colors, paving the way for important advancements in quantum-electrodynamics—the field of science that describes how light and matter interact. In time, the team’s findings are likely to impact developments in optical and quantum communication, and precision measurements of frequency, time and…
Bitcoin Could Either Become Preferred Currency For International Trade Or Face a ‘Speculative Implosion,’ Citi Says
An anonymous reader quotes a report from Reuters: Bitcoin rose nearly 7% on Monday as risk assets rallied after last week’s bond rout cooled, with Citi saying the most popular cryptocurrency was at a “tipping point” and could become the preferred currency for international trade. With the recent embrace of the likes of Tesla and Mastercard, bitcoin could be at the…
