Researchers have obtained the first-ever photographs of the Cozumel dwarf fox (Urocyon sp.), an elusive dwarf fox living on the Caribbean island of Cozumel, off Mexico’s Yucatán Peninsula. Captured in September 2023, the images provide the first confirmed evidence since 2001 that the elusive animal still survives on the island.

The extinct Eurasian cave lion (Panthera spelaea) and today’s African and Asian lions (Panthera leo) belong to separate evolutionary lineages that diverged roughly 1.7 million years ago -- far earlier than previously thought, according to an analysis of 12 cave lion genomes spanning more than 100,000 years. The post Study: Cave Lions were Distinct Species that Occasionally Bred with Ancestors of …

Physicists at the University of Oxford have engineered a new class of ‘cat states’ -- quantum superpositions constructed not from ordinary wave packets, but from deeply exotic, nonclassical components -- opening unexpected paths toward more resilient quantum computers.
