Experiment

Do bacteria mutate randomly, or do they mutate for a purpose? Researchers have been puzzling over this conundrum for over a century.In 1943, microbiologist Salvador Luria and physicist turned biologist Max Delbrück invented an experiment to argue that bacteria mutated aimlessly. Using their test, other scientists showed that bacteria could acquire resistance to antibiotics they hadn't encountered before.The Luria–Delbrück experiment has had a significant effect on science. The findings helped Luria and Delbruck win the…

An elementary school in Gallatin, Tennessee, has made headlines after 19 students and a teacher were sent to the hospital after a dry ice experiment. According to Nashville’s WKRN, the third-grade class was experimenting with dry ice as part of a STEM activity.The experiment was handled under the care of a third-party speaking group, and things seemed to be going fine. However, several students soon began to complain of feeling nauseous and were sent to the school nurse. The nurse then contacted the school…

From the “cinnamon challenge” to the “chubby bunny challenge,” the Internet has seen many viral trends that spread like wildfire thanks to a combination of boredom, curiosity, and a desire for online fame. Some were even conceived for a great cause, such as the “ice bucket challenge,” born as an initiative to encourage donations for ALS research.Still, not everything seen online should be reproduced. A Florida man named John has recently inspired jaw-dropping reactions online after announcing that he would embark on a…

NASA’s Spacecraft Fire Safety Experiment series, Saffire, concluded its final mission with Saffire-VI, marking the end of an eight-year investigation into fire behavior in space. The data collected from these experiments will help NASA design safer spacecraft for future deep-space exploration missions. Credit: SciTechDaily.comThe Saffire experiment series, led by NASA’s Glenn Research Center, concluded with its final mission, Saffire-VI. It investigated fire behavior in space to improve safety and design for future…

Canadian writer Sheila Heti’s 2010 breakout novel sought to interrogate its titular puzzler, How Should a Person Be? It’s become a continuing quest, but over the course of a career that now finds her publishing her 12th book, she’s also asked readers to consider again and again another question: how should prose be? Pairing philosophical inquiry with formal experimentation, she’s drawn inspiration from sources as scattered as reality TV, the I Ching and chatbot utterances, expanding our thinking about structure, character…

I've been very fortunate as a documentary and adventure series filmmaker, having the opportunity to travel all over Canada and the world doing what I love. But my latest project sent me on a mission to a lunar landscape in Canada's Far North — one of the most difficult places I've ever had to reach. For the CBC Short Doc My New Moon Suit, we travelled to Devon Island, nestled in Canada's Arctic, to run our very own test of a new spacesuit. It's here, on the world's largest uninhabited island, that new-concept spacesuits…

After eight years of experimenting with flames in space, NASA lit a fire inside a cargo spacecraft for the last time and sent its Saffire experiment toward a burning reentry into Earth’s atmosphere.Nvidia’s Almost Worth 2 Trillion. Is It a Bubble, or Is It Just Getting Started?NASA’s Spacecraft Fire Safety Experiments, also known as Saffire, came to a fitting end on January 9, flying aboard a Northrop Grumman Cygnus spacecraft that burned up as it plunged through the atmosphere for its planned reentry.The series of…

Xbox has confirmed that four exclusive games will be released on rival consoles, after weeks of speculation.

Lawrence Livermore National Laboratory has published an extensive paper confirming the validity of its 2022 fusion experiment where multiple lasers focused on a sphere of deuterium and tritium to achieve the first fusion ignition in a laboratory.Creating nuclear fusion is relatively easy to produce. All you need are the conditions that place hydrogen isotope ions under the right conditions of heat and pressure to cause them to fuse into helium. In fact, it's so easy that it was the centerpiece of a General Electric…
