Santa Clara County’s ‘ICE-free zones’ questioned as ICE presence grows at jails

Santa Clara County is not intervening as federal immigration agents increasingly stage around its jails, despite county-declared ICE-free zones. Advocates report roughly 10 to 12 agents seen daily at Elmwood and the Main Jail, and the sheriff's office says about 70 people have been detained near county jails since June 2025.

Satellites leak noise that interferes with telescopes and GPS. Here's how to fix it

Researchers report that radio energy leaking from satellites can exceed international limits and disrupt radio telescopes, while modeling indicates direct-to-phone satellites already degrade many geodetic measurements used for GPS. The authors call for wider shielding and routine monitoring before satellite numbers grow further.

Fireworks provide a few minutes of joy, but the economic and environmental costs last much longer

A finance researcher argues that the price of fireworks leaves out costs imposed on others, citing 123 hospital admissions in England in 2024–25 and brief fine-particle pollution spikes around Bonfire Night. A peer-reviewed Dutch study found about 1,000 times as many birds flying during New Year's Eve displays.

Satellite analysis finds little evidence that data centers cause widespread ground warming

A study in Environmental Research Letters using 13 years of satellite imagery from 12 data centers near Tokyo found little evidence that server waste heat causes widespread ground warming. It reported daytime cooling of 1.8–2.2 °C from reflective roofs and negligible nighttime changes directly over facilities.

Overlooked Melbourne patch reveals 45 animal species and more than 40 plant types

A four-month ecological survey of a two-hectare Melbourne site between a waste facility and a shipping container park recorded 45 animal species and over 40 plant types. Records for the site rose from eight to more than 200, and researchers concluded that human-made structures added to habitat and ecological processes.

How a cell surface protein slows down the Ebola virus

Researchers led by Michael Schindler at Tübingen University Hospital found that the cell surface protein CD81 restricts replication of the Ebola virus, while two viral proteins, glycoprotein GP and matrix protein VP40, lower CD81 levels. An antibody binding CD81 reduced infection with authentic virus in cell cultures, though the authors say the mechanisms and any treatment potential remain unresolved.

I tried Apple’s Siri Recaps. They’re surprisingly useful — and a little unsettling

Apple released developer betas of iOS 27.3 and watchOS 27.3 with four Audio Intelligence features for Apple Watch Series 12, including sound and song detection plus Live Rewind and Siri Recaps. Testing Siri Recaps, a reviewer found it captured car-repair deductible and rental details but also saved trivial family chatter.

Long-term temperature records reveal a surprising picture of climate change on Kilimanjaro

A University of Portsmouth study combining 22 temperature loggers with satellite data found that Kilimanjaro warmed near the summit during daytime while middle slopes cooled roughly 0.13–0.14°C per decade. Researchers suggest upslope heathland expansion may influence that cooling, though other factors likely contribute.

Molecular imaging reveals how shape-shifting protein complex captures DNA and holds separate sections together

Researchers at Kanazawa University and Japan's National Institute of Genetics used high-speed atomic force microscopy to watch the Smc5/6 protein complex open and close as it captured DNA and held separate sections together. The Nature Communications study also found Smc5/6 stabilizing twisted DNA into more compact forms.
