Experiment

By Okinawa Institute of Science and Technology (OIST) Graduate University February 10, 2024Recent research reveals that clown anemonefish demonstrate cognitive abilities previously unrecognized, such as distinguishing species by counting the white bars on other anemonefish. Through experiments, it was found that these fish show varying levels of aggression based on the number of bars, suggesting a more complex social structure and cognitive capacity than previously understood. New research suggests that the fish may be…

As It Happens6:05Spider webs catch more than prey. They're also jam-packed with animal DNAJosh Newton probably isn't very popular with spiders. After all, the Australian scientist has a tendency to go around undoing their hard work. "I liken it to when Princess Fiona in Shrek makes some cotton candy for Shrek from spider webs, where she collects a stick and just wraps around the spider web for him. But I do it with a clean, sterile stick," Newton, a PhD candidate in life sciences at Curtin University, told As It Happens…

Scientists have previously established that light can be slowed down in certain scenarios, and a new study demonstrates a method for achieving it that promises to be one of the most useful approaches yet.The researchers behind the breakthrough, from Guangxi University and the Chinese Academy of Sciences in China, say that their method could benefit computing and optical communication.Light zipping through the emptiness of space moves at one speed and one speed only - 299,792 kilometers (about 186,000 miles) per second.…

Construction workers created two colossal caverns, each more than 500 feet long and about seven stories tall, for the gigantic particle detector modules of the Deep Underground Neutrino Experiment, hosted by Fermilab. A third cavern will house utilities for the operation of the detector.

Scientists at CERN are trialling a new type of robot that identify potential radiation leakages in environments challenging to navigate both for humans and other robots employed at the research centre. Called the CERNquadbot, the dog-like robot has successfully completed its radiation protection test at the North Area, the facility’s largest experimental zone. “There are large bundles of loose wires and pipes on the ground that slip and move, making them unpassable for wheeled robots and…

It’s crazy to think of how far video games have come since the original Doom release in 1993. But, as iconic of a game as it is, what has even become more iconic than the game itself is getting it to run on tons of different things. In fact, we’ve seen Doom play on a myriad of things. And now, some scientists have even managed to run Doom on E. coli cells.Yes, you read that correctly. An MIT doctoral candidate by the name of Lauren “Ren” Ramlan has shared video proof of Doom running on cells. Ramlan admitted…

In December 2022, scientists at the US National Ignition Facility announced a historic milestone: for the first time, their laser-powered fusion reaction had 'broken even', producing more energy than it consumed.But advances as big as this need to be rigorously checked – and that can take some time.Importantly, a series of papers detailing the experimental design, technological advancements, and results of the initial breakthrough reaction have just passed peer review, meaning researchers not involved in the work have…

The Big Bad Wolf is going to tear the Ugly Duckling to shreds unless you put that noggin to use. Yes, I’m blending characters from two different fairy tale universes, but maybe the Brothers Grimm meets Hans Christian Andersen is the crossover event we never knew we needed.Alex Winter on Innovative Horror Movies Ensuring that the Ugly Duckling lives to grow into a beautiful swan in this week’s puzzle will be quite difficult, but there is a satisfying solution if you stick with it. Much like a fairy tale, various…

In what just might be one of the most horrifying scientific twists of the year, scientists have managed to keep a pig brain alive for five hours while it was separated from its body. New research published in Scientific Reports details how the researchers accomplished this feat of brain preservation, and it’s absolutely bonkers.For starters, keeping the brain alive outside of the body, away from the connections that typically run between it and the heart, is astounding. However, the fact that the researchers…

A nanoscale-sized glass bead evolving in a potential created through electrostatic or magnetic forces enters a macroscopic quantum superposition state. Credit: Helene HainzerMaking a nanoscale-sized glass bead exhibit quantum effects at macroscopic scales.The distinction between the ordinary world and the quantum realm remains ambiguous. As an object increases in size, its localization intensifies when it undergoes quantum transformation by cooling its motion to absolute zero.Researchers, led by Oriol Romero-Isart from…
