Ontario free to axe Toronto bike lanes, region’s top court rules

Win is significant for region’s premier, Doug Ford, who blames protected zones for city’s traffic ills The Ontario government is now free to rip out Toronto’s bike lanes on its busiest streets after the region’s top court ruled in favour of the province on Friday, overturning a lower court’s decision that decreed removal would violate constitutional rights. The win is significant for Ontario’s premier, Doug Ford, and his government, who have long railed against Toronto’s bike lanes, blaming the protected zones for the city’s traffic ills .

The US’ future policymakers are questioning the standard ‘China threat’ playbook

For years, the conventional wisdom in Washington was that America’s China policy was moving in one direction: tougher. But walk into a classroom at Georgetown, Rice or another US university where the next generation of diplomats and foreign-policy professionals is being trained, and the picture looks less settled. A generation that has grown up with China’s rise is increasingly sceptical of the idea that Beijing should be treated primarily as America’s great strategic rival. That matters because...

China rattled by Trump White House chaos weeks ahead of Xi visit. It has happened before

Just months ago, disorganised planning from Washington in the lead-up to US President Donald Trump’s landmark China visit frustrated Chinese officials. Now, Beijing is watching the same story play out on the other side of the world. With less than six weeks until Chinese President Xi Jinping’s planned trip to Washington – his first state visit since 2015 – Beijing finds itself increasingly unsettled by the chaos within the Trump administration. Sources told the South China Morning Post that...

Delcy Rodriguez’s Castro tribute tests Venezuela’s balancing act between US and China

Venezuelan interim President Delcy Rodriguez’s tribute to Fidel Castro has drawn a blistering rebuke from US Secretary of State Marco Rubio, highlighting the political tensions surrounding Caracas’ rapprochement with Washington even as China seeks to preserve its economic interests in the South American country. Rodriguez marked the centenary of the late Cuban leader’s birth this week by praising Castro as a figure who “transcends time” and invoking his commitment to sovereignty, social justice...

Z.ai entrenó GLM-5.3 para programar mejor. El modelo aprendió de paso a ser mucho mejor en ciberseguridad

Mejorar un modelo de inteligencia artificial para programar ya no significa únicamente conseguir que escriba código con menos errores. Cuando lo entrenamos para desenvolverse durante horas en entornos complejos, utilizar herramientas, revisar resultados y resolver problemas de principio a fin, también estamos empujando habilidades que pueden aparecer en terrenos bastante más delicados. Eso es precisamente lo que Z.ai asegura haber observado con GLM-5.3: mientras escalaba su post-training, las capacidades relacionadas con ciberseguridad crecieron más rápido de lo que la propia compañía…

El Boeing 737 es una maravilla de la ingeniería. También lo es que un dispositivo del tamaño de una moneda altere su aviónica

El Boeing 737 lleva décadas formando parte del paisaje cotidiano de la aviación comercial. Lo hemos visto despegar miles de veces, cruzar aeropuertos de medio mundo y transportar pasajeros en una máquina donde conviven ingeniería, electrónica y procedimientos diseñados para funcionar con enorme precisión . Por eso resulta tan llamativo que una investigación reciente haya puesto el foco no en una gran vulnerabilidad visible, sino en algo casi insignificante por tamaño. Para situarnos, el 737 no es un modelo aislado, sino una extensa familia de aviones de pasillo único que Boeing ha…

Ask Ethan: Why are astronauts weightless while still in Earth’s gravity?

If you stand here on the surface of the Earth, whether at the north pole where the acceleration is greatest or at the summit of Huascarán where it’s the smallest, you’ll be pulled toward the center of the Earth with an acceleration of 9.8 m/s² : the acceleration due to gravity, or “ 1 g ” on the surface of the Earth. Sure, there are tiny variations that will ensue, as your distance from Earth’s center, the speed of the planet’s rotation beneath your feet, and the density and composition of Earth’s crust and mantle aren’t constant, but those variations only lead to variations in the…

This scientist is helping build a missing map of childhood

In 2017, Deanne Taylor attended a presentation at the University of Pennsylvania, just a short walk from her office. A researcher was there to unveil the Human Cell Atlas, an ambitious project that aimed to map every cell in the human body. Taylor was floored, and then concerned. As details emerged, she discovered that the…

Sleep disturbances linked to genetic Alzheimer's risk

A person's sleep patterns could be an early sign of Alzheimer's disease, a new study says. A greater number of micro-awakenings during sleep is linked to a greater genetic risk for Alzheimer's, researchers report in the journal Sleep.

A stress hormone may help the brain repair itself

A surprising stress-related signal may help the brain repair itself after injury. Researchers found that myelin-producing precursor cells rapidly release the stress hormone CRH near damaged brain tissue, helping control how those cells mature and rebuild protective nerve insulation. The same system also influences brain development and the thickness of myelin later in life. The findings could offer new clues about how early-life stress contributes to psychiatric disorders.

Immune cells flood into the aging brain, Stanford scientists discover

Scientists have discovered that the aging human brain may be far less isolated from the rest of the body than once believed. Stanford researchers found that large numbers of immune cells from the blood begin entering the brain as early as middle age, where they can transform into microglia, the brain’s specialized immune cells. The finding overturns a long-standing assumption that these cells remain largely separate from the body’s immune system throughout life.
