Scientists use sound waves to deliver a new attack on deadly brain cancer

Scientists at the University of Virginia have developed a promising new strategy to fight glioblastoma, one of the deadliest and most difficult-to-treat forms of brain cancer. Their experimental approach combines focused ultrasound, tiny nanoparticles, and genetic molecules called microRNAs to attack multiple cancer-driving genes simultaneously.

Physicists created a tiny universe and watched time emerge without a clock

Scientists have created a miniature universe in the laboratory that could help answer one of the biggest mysteries in physics: What is time, and where does it come from? Using 24,000 ultracold atoms, a University of Birmingham researcher built an isolated quantum system that repeatedly expands and contracts, mimicking the Big Bang and a possible Big Crunch. Remarkably, the experiment showed that time could emerge from changes happening inside the system, without relying on an external clock.

Scientists discover that cranberry juice may help fight tooth decay

Cranberry juice may offer an unexpected benefit beyond its reputation for helping prevent urinary tract infections: protecting teeth from decay. Researchers at the University of Illinois Chicago discovered that pure, unsweetened cranberry juice slowed the regrowth of dental plaque bacteria and reduced their production of acids that damage tooth enamel. The secret may lie in naturally occurring compounds called proanthocyanidins, which interfere with harmful bacteria.

NASA University Challenge Ignites Trajectory of Drone Entrepreneur

Five years ago, Gavin Gardner was a Michigan State University engineering student researching next-generation drone technology as part of a NASA grant. Garder expected the research to be demanding – but he was surprised that navigating the financial side of the work presented an even greater challenge. Although Gardner was used to leading fellow students […]

Scientists discover the immune system’s hidden sense of touch

Scientists at McGill University have discovered a surprising new ability of immune cells that could change how we understand long-term immunity. Researchers found that T cells can actually sense how stiff their surrounding tissues are, using these physical signals to help determine whether they develop into long-lasting memory cells that protect against future infections.

Do spiders dream? Scientists just found a surprising clue

Scientists have discovered that spiders may sleep in ways surprisingly similar to humans, complete with distinct sleep stages and a dream-like REM state. Researchers at the University of Bonn studied the Australian jumping spider Portia fimbriata, a remarkably clever hunter known for its sophisticated strategies. By recording the spiders over several days and nights, they found clear evidence of regulated sleep, including a REM-like stage marked by eye movements and muscle twitches.

Bolsonaro's refusal to concede underscores ‘serious’ challenges to Brazil's democratic institutions

Annette Young is pleased to welcome Dr Pedro Perfeito da Silva, Latin American specialist at the University of Exeter. For Dr Perfeito da Silva, Lula's stunning success reflects the convergence of digital organizing, grassroots mobilization, targeted socioeconomic appeals and an effective effort to mobilise opposition to the Bolsonaro political project. As he explains, Lula assembled a coalition that "not only energized his supporters but also attracted voters from groups that had been somewhat skeptical of the government in the first round."

Cornell University bans fraternity parties after alleged gang rape

Cornell University will ban parties and social events at fraternity houses until the end of the academic year, its president said on Tuesday, responding to the outcry over an alleged ​gang rape on ‌campus in 2024. The measure is the strongest reaction yet from Cornell's leadership to a lawsuit ⁠filed by a former undergraduate, Jane Doe, alleging seven men sexually assaulted her during a party. Over the last several weeks, the Ivy League school in Ithaca, New York, and its ‌president, Michael Kotlikoff, have come under heavy criticism over its response to ⁠the allegations.
