A race to militarize artificial intelligence is gearing up. Two years ago, the US Congress created the National Security Commission on Artificial Intelligence (NSCAI). This March, it recommended that the United States must accelerate artificial-intelligence (AI) technologies to preserve national security and remain competitive with China and Russia. This will undermine the United States’ ability

Researchers have developed a strain of SARS-CoV-2 that triggers severe COVID-19 symptoms in mice — an advance that could accelerate the creation of drugs and vaccines and help to illuminate the biology of the disease. Mice aren’t naturally susceptible to SARS-CoV-2 infection. That’s because the virus does not recognize the mouse version of a receptor

Archibald Since Charles Darwin first proposed his theory of evolution, biologists have struggled to fit all life forms — from the tiniest bacterium to the blue whale — onto a tree of life that explains their ancestry. The tree, it turned out, was more of a web. Branches were fused by the

The signature mane, the predatory stealthy movement, the fierce roar-it appears fitting to discover that there is just one species of lion (Panthera leo).  However, there are several subspecies, which are different in appearance and other specific traits. Almost all lions are indigenous to Sub-Saharan Africa, living here and there excluding the deserts and rainforests,

During embryonic development, new cell types emerge with stunning speed and robustness. The process of gastrulation — in which a single layer of cells gives rise to multiple ‘germ layers’ — is fundamental to the early development of most animals. Although studied for more than 150 years, many aspects of gastrulation remain elusive, not least
