Scientists overcome a hidden obstacle to more powerful quantum computers

Scientists have discovered a way to operate multiple silicon qubits simultaneously with remarkable accuracy, overcoming a major challenge in scaling up quantum computers. Their new technique maintained accuracy of approximately 99.9% even when all five qubits were running at once, opening the door to larger and more powerful quantum processors.

A simple liquid can stop cavities without drilling, major study confirms

A simple liquid painted onto teeth in seconds can stop cavities without drilling, injections, or anesthesia, according to a major clinical trial involving young children.

  • Silver diamine fluoride (SDF) stops tooth decay in young children without drilling.
  • Phase III trial with 830 children aged 6 or under in Michigan, New York, and Iowa.
  • 38% SDF solution applied every six months to halt decay in over half of affected baby teeth.
