Canadian Teenager Replicated Archimedes’ Death Ray For a Science Project : ScienceAlert

Legends about the ingenuity of the Greek inventor and mathematician Archimedes were so powerful that for centuries, many scholars have believed he was able to use mirrors to set Roman ships alight more than 2,000 years ago.A Canadian middle schooler, Brenden Sener, designed a science-fair project to see whether such a feat was possible with a miniature version of the death ray.Though he wasn't trying to set anything on fire, he found that his setup – which included heat lamps and mirrors – did significantly increase the…

Researchers find that sea waves once swept Canadian Prairie Provinces

It’s mating season for coyotes. Here’s how to limit encounters and stay safe

It's mating season for coyotes, which means they're more likely to be out and about during the day.With that in mind, the City of Burlington, Ont., is reminding residents what to do if they encounter one, and how to coyote-proof their properties. Last week, the city also updated its bylaws to let wildlife management professionals use firearms but the city's head of bylaw says that's not to make it easier to kill coyotes but makes the response require less staffing."Coyotes have always been here. People just didn't notice…

Privately owned Odysseus lander makes first U.S. moon touchdown in half-century

A private lander touched down on the moon Thursday but managed just a weak signal back, as flight controllers scrambled to gain better contact with the first U.S. spacecraft to reach the lunar surface in more than 50 years.Tension mounted in the company's command centre in Houston, as controllers awaited a signal from the spacecraft some 400,000 kilometres away, which arrived about 10 minutes later.Despite the spotty communication, Intuitive Machines, the company that built and managed the craft, which is called Odysseus,…

Canadian contribution to private lunar lander could lead to a telescope on the moon

The first private spacecraft to softly land on the moon carries a Canadian instrument that will test the possibility of building an observatory at the Lunar south pole.The phone booth-sized lander by Intuitive Machines, named Odysseus, launched on Feb. 15 and touched down on Thursday near a small impact crater about 300 kilometers from the moon's south pole.It was a stressful event with navigation and communication issues, but 15 nail-biting minutes after it landed, mission control confirmed that they were receiving a…

Time in space is bad for the bones. N.S. prof’s research could help humans on Earth

For two decades, Tamara Franz-Odendaal has been studying how space travel affects the human skeleton.Because of the absence of gravity in space, astronauts experience bone loss when they get back to Earth."We always think of it as just the scaffold that kind of keeps the body together, but it's a really dynamic tissue," said Franz-Odendaal, a professor at Mount Saint Vincent University.Using a device known as a random positioning machine, which simulates microgravity experiments on Earth, Franz-Odendaal is conducting a…

World’s globetrotting animals at risk due to habitat loss, climate change

During its nesting season, the marbled murrelet, known affectionately among bird watchers as a "strange, mysterious little seabird," lays a single egg in the thick mosses that grow on the branches of British Columbia's old-growth forest canopy.With some of those forests under threat from logging, the small black-and-brown mottled seabird is considered threatened, too.The marbled murrelet is among a growing number of migratory species animals facing a perilous future, a new UN report found.  "The solution for the marbled …

Swordfish are moving north in Canadian waters

Canadian scientists and fishermen are tracking the northward movement of swordfish into Newfoundland waters, where the prized fish is being caught in large numbers on the Grand Banks and Flemish Cap.What no one knows is if it's the result of a warming ocean or a cyclical — and temporary — event."It's still unclear whether this is becoming the new normal due to climate change or if the biomass will eventually shift back again as we think it did historically," said Fisheries and Oceans Canada biologist Kyle…

Lunar lander launched, separated successfully in latest U.S. moon attempt

A moon lander was launched from Florida early on Thursday on a mission to conduct the first U.S. lunar touchdown in more than a half century and the first by a privately owned spacecraft.The Nova-C lander built by Houston-based Intuitive Machines, dubbed Odysseus, lifted off shortly after 1 a.m. ET atop a two-stage Falcon 9 rocket flown by SpaceX from NASA's Kennedy Space Center in Cape Canaveral.A live NASA-SpaceX online video feed showed the two-stage, 25-storey rocket roaring off the launch pad and streaking into the…
