In 1910, Thomas Jennings fled a murder scene, but he left behind a clue that would seal his fate: a perfect impression of his fingerprints in the drying paint of a railing, outside the house where he'd committed the crime. Jennings' fingerprints were the first ever to be used as evidence in a criminal investigation,… Continue reading Why Do We Have Fingerprints?

Dark energy: Understanding the mystery force that rules the universe
Dark energy dominates the universe, and could lead it to a cold, bleak end. But that’s not to say we have much clue what it is or how it works Source: https://www.newscientist.com/article/mg24432601-900-dark-energy-understanding-the-mystery-force-that-rules-the-universe/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Why is Mars sometimes bright and sometimes faint?
In 2018, Mars was brighter in our sky than it had been since 2003. In 2019, Mars was mostly faint and inconspicuous. But 2020, here we come! Source: https://earthsky.org/astronomy-essentials/why-is-mars-sometimes-bright-and-sometimes-faint…

Smartphone Videos Can Now Be Analyzed To Locate a Shooter
Researchers at Carnegie Mellon University have found that videos captured by smartphones can be useful for determining the location of a shooter. Gizmodo reports: The Video Event Reconstruction and Analysis system — or VERA, for short — was developed at CMU’s Language Technologies Institute with the cooperation of SITU Research who shared its expertise on ballistics and architecture, and the tool…
George Lucas Has Apparently Changed the Famous Greedo Scene In 1977’s Star Wars Again, For Disney+
Freshly Exhumed shares a report from The Guardian: George Lucas, whose departure from all things Star Wars seems to have been greatly exaggerated — appears to have yet again doctored the famous Greedo scene in 1977’s Star Wars [prior to it being shown on the Disney+ streaming service]. The scene depicts the Mos Eisley cantina in which Harrison Ford’s Han Solo…
Whoa! Check out this giant geode
Scientists recently studied the formation of the huge crystals inside the giant geode of Pulpí, located deep in a Spanish mine. They found that temperature fluctuations – maybe from climate or maybe from geothermal systems – amplified a natural process that grew the crystals, ripening them over thousands of years and making them literally crystal clear.

How the 2018 Olympic Cyberattack Was Traced To Russian Hackers
Sparrowvsrevolution writes: In a lengthy article, Wired tells a newly detailed narrative of the cyberattack on the 2018 Winter Olympic games, which hit the Olympics network during the opening ceremony. The piece details how the malware used in that attack was designed to incorporate multiple sophisticated false flags, and how forensic analysts overcame those red herrings to eventually trace the attack…
Astronomer probes idea of ET ‘lurkers’
What would an extraterrestrial intelligence need to observe Earth, long-term, from nearby? Materials, a firm anchor, concealment? Earth’s co-orbital objects, or quasi-satellites, might be the ideal place to “lurk.” Source: https://earthsky.org/space/alien-lurker-probes-co-orbital-asteroids-earth…
Non-thermal emission from cosmic rays accelerated in HII regions
Radio observations at metre-centimetre wavelengths shed light on the nature of the emission of HII regions. Usually, this category of objects is dominated by thermal radiation produced by ionised hydrogen, namely protons and electrons. A number of observational studies have revealed the existence of HII regions with a mixture of thermal and non-thermal radiation. The latter represents a clue to the…
