S1Ultrasound waves zapped at the brain are being used to treat everything from hand tremors to addiction  One in four people has a mental disorder, according to the World Health Organization. If you’re lucky enough to live in a wealthy country, treatment will usually involve some form of medication – which can cause more issues than it fixes.
The reason for that lies in the depths and complexities of the human mind. It is made up of a maze of pathways that connect the different parts of the brain. They are in turn governed by chemicals that dictate our thoughts, emotions and actions. When a person has psychiatric disorders such as depression, anxiety or addiction, this intricate landscape is often clouded in shadow.

S11What Actually Happened To The 'Doomsday Glacier?' Here's What Satellite Data Shows The world’s widest glacier isn’t as grounded as scientists once thought. Relatively warm seawater is rushing underneath Antarctica's Thwaites Glacier, contributing to rapid melting and global sea level rise, according to a study published May 20 in the journal Proceedings of the National Academy of Sciences.
The shifting mass of ancient frozen ice, larger in area than Florida, is sometimes called the Doomsday Glacier, because of its potential to contribute to rising tides worldwide. Thwaites itself holds enough water volume to raise sea levels by about two feet, which is enough on its own to impact millions of people living in coastal areas around the globe. Then, there’s the additional interior ice of the West Antarctic shelf where melting would rapidly accelerate with the loss of Thwaites Glacier — eventually leading to an additional estimated eight feet of sea level rise over the course of centuries, according to previous research.

S12Is Boeing's Starliner An Anomaly, Or Is Space Flight Just Really Hard? The vehicle has experienced a string of issues, but so did most spacecraft that came before it.
NASA and its space aviation partners are in the midst of a major problem. Their newest human-rated spacecraft, Boeing’s Starliner, is in the middle of a string of issues. The latest? A second helium leak. While it might seem easy to place full blame on Boeing, in reality, rocketry is, put simply, extremely difficult.

S15Why the upcoming South African election is a massive milestone for the ruling ANC South African’s governing party, the African National Congress (ANC), is in trouble. After 30 years in charge, it is scrambling for support ahead of the upcoming national elections.
The ANC has run the country since the end of apartheid in 1994, initially with Nelson Mandela as its leader. Crumbling infrastructure, particularly to do with electricity supply, a growing lack of employment opportunities, and the perception of elite corruption have all eroded the promise and the early nobility of Mandela’s emergence on to the South African government stage.

S16How Detroit techno is preserving the city's beating heart in the face of gentrification For over two decades, Detroit has celebrated its status as the birthplace of techno with an electronic music festival held over Memorial Day weekend.
But like the city around it, the festival has changed. At its inception, the event was free and focused on techno music and Detroit musicians, primarily the Black Americans who started techno – just as house music was developing in Chicago – in the mid-1980s. Now, the price of a weekend ticket is US$309, plus a $46.15 service fee. And some festivalgoers have noted it no longer draws as many Black attendees as it once did or as one would expect, given the racial makeup of the city. It has long since dropped “Detroit” from its name, rebranding as the Movement Electronic Music Festival in 2006.

S17Ukraine recap: Putin on top as Kyiv scrambles to play catch-up on the battlefield Vladimir Putin has been looking pretty chipper of late. Two weeks ago saw him wearing his trademark vulpine smile as he presided over the Victory Day commemorations in Moscow. It was a rather more upbeat occasion than in the two years previously, given recent Russian successes on the battlefield. Then, pausing briefly to unleash a fresh offensive against the Kharkiv region in northeastern Ukraine, he was off to Beijing where he and the Chinese president, Xi Jinping, agreed on closer ties and deeper military cooperation, “to counter Washington’s destructive and hostile course”.
In the interim, Putin has rearranged Russia’s military establishment, shifting several key players including erstwhile defence minister Sergei Shoigu, who has become national security minister. Shoigu’s replacement is deputy prime minister, Andrei Belousov, an economist. The rationale behind this manoeuvre is to hasten the transition of Russia’s economy fully on to a war footing. But it must be added that the Russian leader also likes to keep his subordinates on their toes and encourage rivalries.

S18Vaping in schools: Ontario's $30 million for surveillance and security won't address student needs The province’s security investments are fear-driven responses to a real problem: Statistics Canada explains that “vaping to reduce stress has increased during the COVID-19 pandemic for those aged 15 to 19, and was reported as the main reason for vaping within this age group.”
Detectors and other surveillance technologies fail to address the stressors students are coping with, particularly those most vulnerable to systemic neglect. Rationale for their efficacy is also unclear.

S19These tips can help keep you safe during a potentially severe 2024 wildfire season High temperatures and widespread drought fuelled over 6,600 fires, burning a record-breaking 18.4 million hectares, an area more than double the size of New Brunswick. The fires emitted nearly 480 million tonnes of carbon, five times the emissions of an average season, turning the skies hazy and orange and blanketing much of North America in wildfire smoke for weeks.
Many regions of Canada experienced over 40 days where air pollution concentrations exceeded the World Health Organization’s air quality guidelines, leading to periods where Canada had some of the worst air quality in the world.

S20You leave a 'microbe fingerprint' on every piece of clothing you wear - and it could help forensic scientists solve crimes When you think of a criminal investigation, you might picture detectives meticulously collecting and analysing evidence found at the scene: weapons, biological fluids, footprints and fingerprints. However, this is just the beginning of an attempt to reconstruct the events and individuals involved in the crime.
At the heart of the process lies the “principle of exchange” formulated by the French criminologist Edmond Locard in the early 1900s, which states that “every contact leaves a trace”. The transfer of materials between the parties involved in a crime (the victim, the perpetrator, objects, the environment) forms the basis for reconstructing the events.

S21S22Multiple sclerosis: blood test that tracks immune response could be first step in developing better treatments An estimated 2.8 million people worldwide have multiple sclerosis (MS). This autoimmune condition is the result of the immune system damaging parts of the nerves in the brain and spinal cord, which can lead to problems with movement, vision, balance and sensation.
While many MS symptoms can be managed, there’s currently no way to cure or prevent the condition. This is due to the complex immune response that leads to this disease. But a blood test recently developed by me and my colleagues has allowed us to estimate the strength of the immune response in people with MS.

S23S24I want to keep my child safe from abuse - but research tells me I'm doing it wrong Child sexual abuse is uncomfortable to think about, much less talk about. The idea of an adult engaging in sexual behaviors with a child feels sickening. It’s easiest to believe that it rarely happens, and when it does, that it’s only to children whose parents aren’t protecting them.
This belief stayed with me during my early days as a parent. I kept an eye out for creepy men at the playground and was skeptical of men who worked with young children, such as teachers and coaches. When my kids were old enough, I taught them what a “good touch” was, like a hug from a family member, and what a “bad touch” was, like someone touching their private parts.

S25S26Animals self-medicate with plants - behavior people have observed and emulated for millennia When a wild orangutan in Sumatra recently suffered a facial wound, apparently after fighting with another male, he did something that caught the attention of the scientists observing him.
The animal chewed the leaves of a liana vine – a plant not normally eaten by apes. Over several days, the orangutan carefully applied the juice to its wound, then covered it with a paste of chewed-up liana. The wound healed with only a faint scar. The tropical plant he selected has antibacterial and antioxidant properties and is known to alleviate pain, fever, bleeding and inflammation.

S27S28The Biggest Sci-Fi Franchise of the Year Just Lost Its Director -- Here's Why That's a Good Thing Adam Wingard, the wizard behind Godzilla x Kong, isn't coming back for a third movie. Here's why that's not the end of the world.
The most unstoppable shared cinematic universe of the moment doesn’t concern superheroes, but instead, giant monsters who smash things. While film critics — or even fans of monster movies in general — struggle to take Godzilla x Kong: The New Empire seriously, the movie is impossible to ignore. So far, it’s earned $564 million at the box office, making it the highest-grossing Godzilla movie of all time and, at the moment, the second-biggest movie of 2024.

S29Kia's Most Affordable EV Yet Gets More Than 300 Miles of Range Kia revealed its EV3, an all-electric compact car that’s targeting a wider audience with its more affordable price and solid range. It still matches the boxy design language of its older siblings, the EV6 and the larger EV9, but in a more approachable package.
While we’ve been teased with enough mini EVs that are better suited for smaller European cities, Kia wants to bring the EV3 to the U.S. in the coming years. Until then, we’ll have to make do with the slim number of existing options, like the Hyundai Kona, or wait for the comeback of the Chevrolet Bolt.

S3017 Years Later, the Longest-Running Sci-Fi Show Is Attempting to Pull Off the Impossible One of the biggest problems facing any long-running franchise is finding room to improve. After Return of the Jedi, it’s hard to replicate the joyous victory of the Rebellion. After Endgame, it’s hard to top saving billions of lives. Doctor Who has more than 60 years of history to top, but with a new deal with Disney+ (and a new Doctor) the series is still attempting to keep things fresh.
A recent interview with returning showrunner Russell T. Davies reveals that the next episode, “73 Yards,” will contain a groundbreaking new villain, but is that even possible after an old episode contained one of the most creative monsters seen on sci-fi TV?
