8:46 PM | Brain-Like Circuits Can Mimic Pavlov's Dogs
Originally published: Dec 15 2014 - 1:45pm, Inside Science News ServiceBy: Charles Q. Choi, Contributor(Inside Science) -- Artificial electronic circuits that mimic the pathways connecting neurons in the brain can learn, unlearn and store memories, researchers have reported. These inventions could not only help researchers better understand how the brain works, but could also lead to advanced new computers.Brains are the most powerful computers known. This is due in large part to their […]

8:44 PM | Carbon-trapping nanopore sponges can cut greenhouse gases
In the fight against global warming, carbon capture is gaining momentum, but standard methods are plagued by toxicity, corrosiveness and inefficiency. Using a bag of chemistry tricks, materials scientists have invented low-toxicity, highly effective carbon-trapping 'sponges' that could lead to increased use of the technology.

6:31 PM | New Japanese ALMA Video Is Breathtaking
Topically transcending cultures, the reasons the new Japanese ALMA video below might not get be as widely shared in America would be insignificant reasons.ALMA (the Atacama Large Millimeter/submillimeter Array) is one of my favorite projects in astronomy, yielding some of the most freaking ridiculously beautiful data humans have yet to discover and render.  The most well known ALMA related image is probably this one, the Antennae Galaxies composite of ALMA and Hubble […]

2:59 PM | Il secondo principio di relatività
Durante i suoi primi passi, la relatività speciale incrociò la strada con l'elettrone e la ricerca della sua massaLa relatività speciale di Albert Einstein proponeva alcuni elementi rivoluzionari, fornendo innanzitutto una serie di strumenti matematici e di discorsi epsitemologici a supporto di una serie di osservazioni apparentemente assurde, prima fra tutte la non conservazione delle equazioni di Maxwell sotto l'azione delle trasformazioni di Galileo.Le trasformazioni di […]

Do Itty-Bitty Meteorites Harbor Secret Superconductors? The pretty gems you see above are in fact tiny meteorites. Scientists are hopeful that some of them may contain unique compounds new to science — high-temperature superconductors. Superconductors conduct electricity without resistance, a nifty property that makes them useful in all kinds of electronics applications. But all the superconductors we know of have to be very, very cold to work, making them impractical for many […]
