A new study of the human genome has discovered evidence that humanity nearly went extinct nearly 900,000 years ago, due to the species having dwindled to less than 1,300 reproductively-capable individuals, quite probably from a climate-related disruption. This genetic bottleneck persisted for over 100,000 years, and would explain a gapread more
A team of researchers with Cambridge University has determined that the common cuttlefish has the cognitive ability to postpone the instant satisfaction that can come from an immediate reward if it holds out for a more attractive prize that is made available later, through a test originally designed to studyread more

Although there is the outside chance that ’23 mightn’t reach this ignominious landmark, it would require global surface temperaturesread more
In what may be the first sign of life detected beyond our Solar System, the James Webb Telescope has detected the signature of a chemical compound that is known to only be produced by biological organisms, in the atmosphere of an exoplanet 124 light years from Earth. Although its detection is stillread more
