Recent Scientific Discoveries: Smallpox DNA, CERN Plasma, Quantum Anyons, and New Cavefish

A summary of 2026 scientific findings about ancient smallpox DNA, primordial matter at CERN, universal quantum gates, a rare Alabama cavefish, and AI in cryptography.

What did a 2026 study reveal about how smallpox reached the Americas?

An analysis of ancient DNA from the leg bones of an adult man and woman in South America, who likely died between 1492 and 1631, showed the smallpox strain sits between medieval European strains and later versions. This provides molecular evidence that colonization brought the disease from Europe, although the exact transmitting population remains unclear.

What primordial matter have recent CERN experiments detected?

In 2026, all four major LHC experiments—ALICE, ATLAS, CMS, and LHCb—reported signs of quark–gluon plasma from oxygen–oxygen and neon–neon collisions. The state forms at temperatures more than 100,000 times hotter than the Sun's center and is thought to have filled the universe moments after the Big Bang.

How did scientists demonstrate a universal gate set using non-Abelian anyons?

A team from UChicago, Harvard, Stony Brook, and Quantinuum paired non-Abelian anyons to encode topological qutrits and combined braiding and fusion to show operations that can generate any quantum computation. Their Nature paper, published 15 July 2026, is titled “Universal gates from braiding and fusing anyons on quantum hardware.”

What is the demon cavefish discovered in Alabama?

The new species is an eyeless, pigmentless cavefish with a hunchback, spiny rays, and a unique snout; its translucent skin reveals its brain. Described in Scientific Reports on July 6, it appears to exist only at a single site, possibly making it one of the rarest fish in the world.

How have AI tools produced overlapping results in cryptography?

Two separate research groups used AI to produce proofs for the same problem in unclonable encryption, a specialized area of quantum cryptography. The near collision, which has not yet been peer-reviewed, highlights how AI may speed research and blur traditional notions of independent discovery and credit.

What makes the 2026 ancient smallpox DNA study significant?

It provides the first molecular proof that strains of smallpox in the Americas evolved from European forms. By placing an ancient South American strain between medieval European strains and later variants, scientists gave concrete genetic support for what historians had long inferred from historical records.
