Are ad blockers backfiring? New study finds they may show you worse ads
- A new study suggests that ad blockers may not be as effective as users think and could even lead to worse ads being shown.
- The study focused on Adblock Plus' 'Acceptable Ads' feature, which aims to balance ad support for websites with providing users a better browsing experience.
- Users with the Acceptable Ads feature turned on saw 13.6% more problematic ads than those without any ad blockers, including ads with inappropriate content and misleading claims.
- The study raises concerns about ad platforms potentially targeting users with ad blockers with lower-quality or riskier ads, posing privacy risks. The research will be presented at the Privacy Enhancing Technologies Symposium on July 15, 2025.

What is the optimal setting for your air conditioner
- Air conditioners operate on the principle of moving heat from a cold area to a high-temperature area, requiring electricity to power compressors.
- The optimal temperature setting for an air conditioner is around 80 degrees Fahrenheit, slightly lower than body temperature, to allow efficient radiation transfer of excess heat from the body.
- Large temperature differences between indoor and outdoor environments cause stress on the body, requiring energy for temperature balance.
- The efficiency of air conditioners depends on building insulation; it is better to adjust usage based on insulation quality, with considerations for natural airflow and sunlight management.

New smart sensor could sniff out indoor pollution—and heals itself
- Researchers at Carnegie Mellon University have developed a new formaldehyde sensor for indoor use with a special polymer coating that extends its life and allows it to regenerate.
- The sensor is based on MXene, known for its electrical properties and gas detection abilities, but typically vulnerable to air and humidity exposure.
- A nano-scale polymer coating made using Chemical Vapor Deposition protects the sensor, extending its effectiveness to over five months, compared to only two months without the coating.
- The coating not only protects the sensor but also helps it regenerate. When its performance fades, introducing humidity revives its sensitivity by about 90%—making it a sustainable and reliable solution for monitoring indoor air quality.
