'Flying focus' laser overcomes key limitation in plasma-based particle accelerators
Researchers used a specially engineered laser pulse called a flying focus to accelerate electrons to more than twice the energy predicted by traditional dephasing limits in plasma-based accelerators. The flying focus laser counteracts dephasing, a longstanding limitation that prevented electrons from gaining energy over the same distance.

Creating cleaner chemical reactions that run on oxygen and produce only water as waste
Scientists developed chemical reactions that use oxygen to drive organic transformations while producing only water as waste, mimicking how natural enzymes rearrange oxygen's electrons to activate reactions. The approach addresses oxygen's unusual electronic configuration that normally slows reactions with organic matter.
New 'shape-shifting' architecture brings versatility to photonic quantum computing
Researchers developed a shape-shifting photonic architecture that enables light-based quantum computers to perform a broader range of computations by overcoming photons' natural lack of interactions. The new system uses reconfigurable components to manipulate quantum information carried by light particles across multiple processing modes.
As Canada’s captive belugas arrive in the US, questions linger about their future
Thirteen beluga whales from a closed Canadian theme park arrived in the United States through two transfers in July and August. Six whales moved on July 21, followed by seven whales on August 3, as part of an emergency relocation from Marineland.
A banana byproduct transforms farm waste into profits in Bangladesh
Banana stems left after harvest are being processed into fiber for textiles, yarns, and handicrafts in Bangladesh, where bananas represent 20% of all fruit crops. The extracted banana fiber serves as a biodegradable material that transforms agricultural waste into manufactured products.
Vitamin C may fight cancer — but not the way scientists once thought
Intravenous vitamin C reaches vastly higher concentrations than pills and may damage vulnerable cancer cells while reducing treatment side effects. Early studies suggest this approach could improve outcomes for some patients, though it functions more like an experimental drug than a supplement.
Thermal drones deployed in Kenya’s Amboseli Park to tackle human-elephant conflict
Thermal imaging drones were deployed in Kenya's Amboseli National Park to help monitor elephants and reduce conflicts with nearby farmers. The technology allows rangers to detect elephants at night, enabling them to chase animals away before they damage crops on farms like those within 30 kilometers of the park.
New autism therapy shows surprising benefits even in adult mice
Blocking the glycine transporter SLC6A20 restored brain signaling and improved social, communication, and repetitive behaviors in autism-related mouse models. The treatment also showed lasting effects in adult mice and functioned in human brain organoids.
UCLA scientists discover how to guide heat like light at room temperature
Scientists demonstrated that heat can travel through crystal in focused, directional waves at room temperature rather than dispersing randomly. This discovery could enable routing heat away from sensitive components in advanced chips and quantum devices.
Scientists tracked 12 people in Antarctica for 10 months—what happened could shape future Mars missions
Scientists studied 12 people isolated in Antarctica for ten months and found that frequent contact with the same crew members increased tension and mistrust. The isolated group gradually split into smaller factions based on cultural and language differences, a pattern relevant to planning extended space missions.
Earth’s molten core suddenly reversed direction — and scientists don’t know why
Earth's molten iron core beneath the Pacific reversed direction, a change detected by satellite data of the planet's magnetic field. Scientists observed the surge is already weakening, suggesting the deep-Earth shift may be part of a natural cycle.
Wearable ultrasound patch boosts REM sleep without drugs or surgery
A wearable ultrasound patch shortened time to REM sleep by 43 minutes and extended REM duration by approximately 16 minutes in a 28-person study. The device produced signs of improved stress regulation and altered brain circuits associated with emotion without requiring medication or surgical intervention.
Protecting primates could protect thousands of other species, study finds
A new study recommends prioritizing primate habitat protection as a conservation strategy, since safeguarding primate territories also preserves habitats for thousands of other species. This umbrella species approach could protect multiple species simultaneously through protecting the large areas that primates require for survival.
Scientists find unexpected life on Ötzi the Iceman’s 5,300-year-old body
Scientists identified ancient gut bacteria and cold-loving yeasts living on Ötzi the Iceman's 5,300-year-old frozen body. The researchers separated microbes present during his lifetime from those that arrived after death, finding organisms that survived in the glacier for thousands of years.
