Researchers in Canada got most of what they were hoping for in the country's 2024 federal budget, with a big boost in postgraduate pay and more funding for research and scientific infrastructure. From a report: "We are investing over $5 billion in Canadian brainpower," said finance minister Chrystia Freeland in her budget speech on 16 April. "More funding for research and scholarships will help Canada attract the next generation of game-changing thinkers." Postgraduate students and postdoctoral researchers have been advocating for higher pay for the past two years through a campaign called Support Our Science. They requested an increase in the value, and number, of federal government scholarships, and got more than they asked for. Stipends for master's students will rise from Can$17,500 (US$12,700) to $27,000 per year, PhDs stipends that ranged from $20,000 to $35,000 will be set to a uniform annual $40,000 and most postdoctoral-fellowship salaries will increase from $45,000 to $70,000 per annum. The number of scholarships and fellowships provided will also rise over time, building to around 1,720 more per year after five years. "We're very thrilled with this significant new investment, the largest investment in graduate students and postdocs in over 21 years," says Kaitlin Kharas, a PhD student at the University of Toronto, Canada, and executive director of Support Our Science. "It will directly support the next generation of researchers." Although only a small proportion of students and postdoctoral fellows receive these federal scholarships, other funders tend to use them as a guide for their own stipends. Many postgraduates said that low pay was forcing them to consider leaving Canada to pursue their scientific career, says Kharas, so this funding should help to retain talent in the country.

sinij shares a report: Members of Parliament in Canada are expected to vote for up to 15 hours in a row Thursday and Friday on more than 200 Conservative amendments to the government's sustainable jobs bill. The amendments are what's left of nearly 20,000 changes the Conservatives proposed to Bill C-50 last fall at a House of Commons committee. Liberals now contend the Conservatives came up with the amendments using artificial intelligence in order to gum up the government's agenda. The Conservatives deny that accusation.

A Toronto Sun columnist writes that two Canadian civil liberties groups are "sounding alarms" about the proposed new Online Harms Act (C-63): The Canadian Civil Liberties Association (CCLA) and the Canadian Constitution Foundation (CCF) say while the proposed legislation contains legitimate measures to protect children from online sexual abuse, cyber-bulling and self-harm, and to combat the spread of so-called "revenge porn," its provisions to prevent the expression of hate are draconian, vaguely worded and an attack on free speech... "[D]on't be fooled," said CCF executive director Joanna Baron. "Most of the bill is aimed at restricting freedom of expression. This heavy-handed bill needs to be severely pared down to comply with the constitution." Both the CCLA and CCF warn the bill could lead to life imprisonment for someone convicted of "incitement to genocide" — a vague term only broadly defined in the bill — and up to five years in prison for other vaguely defined hate speech crimes. The legislation, for example, defines illegal hate speech as expressing "detestation or vilification of an individual or group of individuals," while legally protected speech, "expresses dislike or disdain, or ... discredits, humiliates, hurts or offends." The problem, critics warn, will be determining in advance which is which, with the inevitable result that people and organizations will self-censor themselves because of fear of being prosecuted criminally, or fined civilly, for what is actually legal speech. "Both the CCLA and the CCF say the proposed legislation, known as Bill C-63, will require major amendments before becoming law to pass constitutional muster," according to the columnist. Some specific complains: The CCF argues that the Bill "would allow judges to put prior restraints on people who they believe on reasonable grounds may commit speech crimes in the future." The CCLA adds that the proposed bill also grants authorities "sweeping new search powers of electronic data, with no warrant requirement," according to the Toronto Sun, and also warns about the creation of a government-appointed "digital safety commission" given "vast authority" and "sweeping powers" to "interpret the law, make up new rules, enforce them, and then serve as judge, jury, and executioner." And in addition, the CCF points out under the proposed rules the Canadian Human Rights Commission "could order fines of up to $50,000, and awards of up to $20,000 paid to complainants, who in some cases would be anonymous." "Findings would be based on a mere 'balance of probabilities' standard rather than the criminal standard of proof beyond a reasonable doubt... The mere threat of human rights complaints will chill large amounts of protected speech." Thanks to long-time Slashdot reader sinij for sharing the article.

It was an idea first proposed by Archimedes, reports CNN. But now, "Brenden Sener, 13, of London, Ontario, has won two gold medals and a London Public Library award for his minuscule version of the contraption — a supposed war weapon made up of a large array of mirrors designed to focus and aim sunlight on a target, such as a ship, and cause combustion — according to a paper published in the January issue of the Canadian Science Fair Journal." For his 2022 science project, Sener recreated the Archimedes screw, a device for raising and moving water. But he didn't stop there. Sener found the death ray to be one of the more intriguing devices — sometimes referred to as the heat ray. Historical writings suggested that Archimedes used "burning mirrors" to start anchored ships on fire during the siege of Syracuse from 214 to 212 BC... There is no archaeological evidence that the contraption existed, as Sener noted in his paper, but many have tried to recreate the mechanism to see if the ancient invention could be feasible. In Sener's attempt at the ray, he set up a heating lamp facing four small concave mirrors, each tilted to direct light at a piece of cardboard with an X marked at the focal point. In this project he designed for the 2023 Matthews Hall Annual Science Fair, Sener hypothesized that as the mirrors focused light energy onto the cardboard, the temperature of the target would increase with each mirror added. In his experiment, Sener conducted three trials with two different light bulb wattages, 50 watts and 100 watts. Each additional mirror increased the temperature notably, he found... The temperature of the cardboard with just the heating lamp and the 100-watt light bulb and no mirrors was about 81 degrees Fahrenheit (27.2 degrees Celsius). After waiting for the cardboard to cool, Sener added one mirror and retested. The focal point's temperature increased to almost 95 F (34.9 C), he found. The greatest increase occurred with the addition of the fourth mirror. The temperature with three mirrors aimed at the target was almost 110 F (43.4 C), but the addition of a fourth mirror increased the temperature by about 18 F (10 C) to 128 F (53.5 C)... Sener was not attempting to light anything on fire, as "a heating lamp does not generate anywhere near enough heat as the sun would," he said. But he believes that with the use of the sun's rays and a larger mirror, "the temperature would increase even more drastically and at a faster rate" and "would easily cause combustion." The powerful weapon wouldn't work on cloudy days, Sener's paper points out, and even a moving ship might diminish its impact. But in an interview with CNN, Sener calls Archimedes' death ray "a neat idea".
