Why Does a VPN Drain Your Battery? Explained for Everyday Users

September 24, 2025 Science Buzzer 2

In today’s digital world, Virtual Private Networks (VPNs) have become essential tools for online security and privacy. Whether you’re browsing public Wi-Fi at a coffee shop or streaming content from another country, a VPN encrypts your internet connection and keeps your data safe. However, many users notice a common problem: their phones or laptops seem to lose battery faster when a VPN is active. Why does this happen? Let’s break it down in simple terms.

Indian scientists reveal how SPIN90 turns on a key cell “builder”

September 17, 2025 Science Buzzer 1

A team of scientists based at CSIR-Centre for Cellular and Molecular Biology (CCMB) in Hyderabad, India has solved an important piece of how cells build their internal skeleton. Using cryo-electron microscopy, the researchers showed how a protein called SPIN90 forms a pair and activates the Arp2/3 complex to start new actin filaments. This work explains a long-standing mystery about how straight actin filaments can be made inside cells and helps us understand cell movement, shape and some disease processes.

The James Webb Space Telescope, known as Webb, is giving scientists new ways to spot atmospheres like Earth’s on distant planets. Webb looks at faint infrared light. That light can carry the fingerprints of gases such as water vapor, carbon dioxide, oxygen, methane and ozone. These are the same gases that help make Earth habitable.
