Astronomers have published a gigantic infrared map of the Milky Way containing more than 1.5 billion objects ― the most detailed one ever made. Using the European Southern Observatory’s VISTA telescope, the team monitored the central regions of our Galaxy over more than 13 years. At 500 terabytes of data, this is the…
Why is there almost nothing on the left hand side of the USA? Water scarcity! We’re missing 300 million Americans. We’re missing 30 global cities west of 100 degrees longitude. We shoul…
Ende 2019 begann die zuvor unauffällige Galaxie SDSS1335+0728 plötzlich heller zu leuchten als je zuvor. Um den Ursachen auf den Grund zu gehen, haben Astronom*innen Daten von mehreren weltraumbasierten und bodengebundenen Observatorien, darunter das Very Large Telescope (VLT) der Europäischen Südsternwarte (ESO)…

Exercise can have benefits at the level of neurons, through chemical and mechanical effects, MIT researchers find. The discovery could inform exercise-related therapies for repairing damaged and deteriorating nerves.
Too much stuff in the periphery of our vision can make it difficult to identify what we’re seeing. Yale researchers now know how that clutter affects the brain.
EDIT: Be warned that this post is angry. If you’re easily offended when someone goes on a rant, then leave now because I’m very unforgiving in several places below. The tone of my writing is unusually harsh, but the people whose work I’m talking about deserve it, and here’s why. Even though I had been working with…
In the largest study of its kind, scientists have shown how protein “biomarkers” predict dementia 15 years before diagnosis.
I got something wrong; introducing Airship Industries
MIT Whitehead and Broad Institute researchers designed an epigenetic editor that can silence the prion protein gene, which could potentially be developed into a therapy against fatal prion diseases. The same approach could be used against other genetic diseases.
“Imagine what mistakes might be found in the raw data if anyone was allowed to look!” – Sholto David
Every 60 seconds the equivalent of a lorry-load of plastic enters the global ocean. Where it goes after that remains largely unknown. But a new ESA Discovery study reported in Nature Communications has proven the concept of monitoring floating plastic litter using satellites.
A ‘tritone substitution’ is a popular trick for making your music sound more sophisticated. I’ll show you a couple of videos with lots of examples. But since I’m mathematici…
