  • Tiny graphene wrinkles create surprisingly powerful electrical effects
    Scientists have discovered that tiny, sharply curved wrinkles in graphene can dramatically alter its electrical behavior, creating surprisingly strong charge separation. The finding suggests future electronics could be tuned by reshaping materials at the atomic scale instead of changing what they’re made of.
  • Ordinary WiFi can now identify you with near-perfect accuracy
    Ordinary WiFi networks could quietly become powerful surveillance tools, allowing people to be identified without cameras, special sensors, or even carrying a connected device. Researchers showed that unencrypted signals routinely exchanged between WiFi devices and routers can be used to create radio-based images of people and recognize them within seconds. In tests involving 197 participants, […]
  • Chemists set electrons free and break a decades-old chemistry barrier
    Chemists have developed a catalyst that breaks a long-standing rule governing which molecules receive electrons during chemical reactions. By releasing electrons directly into solution, the technique could unlock reactions—and potentially useful new molecules—that were previously out of reach.
  • Scientists just 3D printed one of the hardest metals on Earth
    A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials. By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade hardness and opened the door to more efficient manufacturing.
  • Mysterious Milky Way object accelerates protons beyond one quadrillion electron volts
    Scientists have identified LHAASO J1912+1014u as a cosmic accelerator that can push protons beyond one quadrillion electron volts. The finding may help reveal where the Milky Way’s most energetic cosmic rays come from and how they influence the galaxy.
  • New process turns plastic waste into hydrogen fuel while trapping the carbon
    A new chemical process can transform three of the most common plastics into high-purity hydrogen without sorting them first. The technique operates at much lower temperatures than traditional gasification and captures most of the plastic’s carbon in solid or liquid forms instead of releasing it as carbon dioxide.

Introduction to t-test

A t-test is a statistical test used to determine whether there is a significant difference between the means of two groups of data. It is commonly used to compare the means of two groups, such as a treatment group and a control group, or to compare the mean of a ...
