Key Points

To build faster and more energy-efficient computers, researchers need to understand nanoscale magnetic materials. But looking inside these tiny magnets is surprisingly difficult: Modern microscopes only measure the magnetic field outside the material, not the magnetic pattern inside. Because many different internal patterns can produce the exact same field, working backwards has long been a challenge.

El Niño has killed hundreds of children in Sudan

Hundreds of children have died of starvation and disease in a drought in Sudan caused by the record-breaking El Niño. The risk of this leading to a full-blown famine is growing. Almost half the country is experiencing drought, which in some areas is the worst in decades, according to a warning from the Integrated Food Security Phase Classification (IPC), a partnership of the United Nations and charity organisations.

Tesla Unveils Roadster With a Nod to SpaceX Merger

Tesla unveiled its long-delayed Roadster sports car Thursday in Texas, showcasing a prototype that used SpaceX-developed air thrusters to perform aerial flips and accelerate from zero to 60 mph in under one second. Production isn’t expected until 2028, while the flying version will be limited to an invite-only package not approved for public roads. Bloomberg Detroit Bureau Chief David Welch breaks it down on Bloomberg Intelligence.

One-step rapid syphilis test uses layered nanoparticles to detect infection earlier

Penicillin has cured syphilis cases since 1943, but symptoms of the sexually transmitted infection, known as "the great imitator," mimic many other diseases and can come and go without treatment while the infection keeps causing harm. If it remains undetected, it can spread to partners and to babies during pregnancy, causing lifelong effects.

Can social media bans protect young people's mental health? Early research suggests that bans aren't the answer

The year 2026 has been an expensive one for social media platforms. Since March, YouTube and Meta, the parent company of Instagram and Facebook, have settled or paid out in multiple lawsuits totaling more than $17 billion for allegedly acting negligently, deliberately designing their platforms to hook kids and misleading the public about safety and privacy. If these suits are any indication of how states and the public are starting to view social media platforms, more may follow.
