The contention the human brain shrank sharply around 3,000 years ago, coinciding with the establishment of cities, has captured popular and scientific imagination, but new evidence suggests it never happened.

The 12th century BC, when humans were forging great empires and developing new forms of written text, did not coincide with an evolutionary reduction in brain size.

Less than two years after shocking the science world with the discovery of a material capable of room-temperature superconductivity, a team of UNLV physicists has reproduced the feat at the lowest pressure ever recorded.

Did the 12th century B.C.E. -- a time when humans were forging great empires and developing new forms of written text -- coincide with an evolutionary reduction in brain size? Think again, says a UNLV-led team of researchers who refute a hypothesis that's growing increasingly popular among the science community.

Last year's study was sharply criticized by a team of scientists from UNLV, who found many ambiguities in it.

New research has demolished previous theories about evolution, as researchers find that human brains did not shrink 3,000 year ago.

The Southern Nevada Health District announced Thursday that it had received nearly 3,000 additional doses of monkeypox vaccine, as the United States declared a public health emergency to bolster the federal response to the spread of the disease.
