mapping

By Mary Lynn Reed, Professor of Mathematics, Rochester Institute of Technology August 26, 2022The math of threes is surprisingly powerful.It’s difficult to imagine that three random words have the power to both map the globe and protect your private data. The secret behind this amazing power is just a little bit of math.What3words is an app and web-based service that provides a geographic reference for every 3-meter-by-3-meter square on Earth using three random words. If your brain operates more naturally in the Imperial…

Scientists have made a major advance toward understanding the molecular mechanisms that are involved in the creation of spatial maps in the brain.Research in mice illuminates the molecular mechanisms that underlie spatial mapping in the brainResearchers found that a gene called Fos plays a key role in helping the brain use specialized navigation cells to form and maintain spatial mapsThe findings bring us one step closer to a complete understanding of how the brain creates memories of spatial maps for navigationAnytime we…

PS5 DualSense Edge wireless controller has been announced. On Tuesday, at Gamescom Opening Night Live, Sony unveiled their new premium-grade controller for the PlayStation 5. At first glance, the controller looks similar to the normal PS5 DualSense, but comes with extra perks to up the standards. The new DualSense Edge wireless controller is “ultra-customisable,” letting you swap out thumbstick caps and set control mappings to suit your taste. The DualSense Edge is essentially Sony's (very belated) answer to Xbox's Elite…

Combining research with cutting-edge technology, a Delhi-based hospital launched a "brain mapping device" and claimed it was the first-of-its-kind gadget in the country. With the advent of such personalised brain mapping, treatment for brain tumours and other brain surgeries has become much safer, and due to the accuracy, damage to important brain areas can be avoided, it said in a statement. "In a first-of-its-kind technology to be launched, with a combination of decades of research with cutting edge technology, IBS…

IN FOCUS Scientists rallied outside Canada’s Parliament on 11 August, carrying a 70-meter-long letter with more than 7000 signatures. The letter to lawmakers calls for increases in the stipends paid by graduate student scholarships and postdoctoral fellowships awarded by the Natural Sciences and Engineering Research Council of Canada. “We can’t do science if we can’t pay rent,” one rallygoer’s sign read. COVID-19 U.K. OKs anti-Omicron vaccine The United Kingdom this week…

The titular abyss in the manga and anime series Made in Abyss is a large pit of about 1,000 meters in diameter and at least 20,000 meters deep. Its seven layers are packed full of ancient artifacts of unfathomable value, natural wonders, and terrifying creatures. While it's safe for delvers who want to explore the mysteries of the abyss to climb down (not taking the predatory creatures into account), one is immediately struck by the strains of ascension upon attempting to climb back up again. The strains of ascension…

Diving into the Unshashable Type errorA common issue all Python developers face at some point (or in reality, many times) is a TypeError with the magic words unhashable type. We can all agree that it does not sound good and can get close to scary without the proper context.Python is a language heavily built on top of dictionaries. For example, that is how namespaces or classes store their functions and attributes. Understanding how dictionaries work beyond Python’s API can help us make sense of this data structure and…

Can we all admit that it was starting to look decidedly hairy for Marvel prior to last week’s info-splurt of a Comic-Con panel? After shaping the Hollywood architecture for more than a decade, the Disney-owned superhero studio has in the past nine months released a trio of movies – Eternals, Doctor Strange in the Multiverse of Madness and Thor: Love and Thunder – that if not quite duds, certainly came nowhere near the top ranks of the critical pantheon.With a lingering sense that any movie not part of the Multiverse Saga…

REEF TOWERSOUTH PACIFIC, 50 MILES EAST OF CAPE YORK PENINSULA, AUSTRALIA Scientists at James Cook University in Australia were charting underwater habitats just beyond the northern end of the Great Barrier Reef using multibeam sonar when they came on a freestanding coral reef tower 1,640 feet tall—taller than the Empire State Building. The base of the wedge, shaped like a shark fin, is almost a mile across, and the tip is only 130 feet below the sea surface. Subsequent dives by a remotely operated vehicle showed the tower…
