Neanderthals created stone tools held together by a multi-component adhesive, a team of scientists has discovered. Its findings, which are the earliest evidence of a complex adhesive in Europe, suggest these predecessors to modern humans had a higher.....»»
Fire is a chemical reaction—here"s why Australia is supremely suited to it
Over the last 15 million years, Australia has slowly dried out. After humans arrived more than 65,000 years ago, they learned to use fire to their advantage. Today, fire weather is getting more frequent—and fires are following as the world heats up.....»»
Researcher: A long voyage to Mars in a confined space could raise stress levels and make the journey more challenging

Bat "nightclubs" may be the key to solving the next pandemic
Bats carry some of the deadliest zoonotic diseases that can infect both humans and animals, such as Ebola and COVID-19. In a recently-published article in the journal Cell Genomics, a Texas A&M research team has revealed that some species of bats are.....»»
Nature"s checkup: Surveying biodiversity with environmental DNA sequencing
A thousand kilometers south of Tokyo, far into the largest ocean on Earth, lies a chain of small, volcanic islands—the Ogasawara Islands. Nature has been able to develop on its own terms here, far from both humans and the warm Kuroshio current, whi.....»»
NASA vows to battle "organizational silence" as problems arise amid Artemis delays
NASA was riding a high after the overall success of Artemis I when the uncrewed rocket made a test run to the moon and back in 2022, so the message remained full steam ahead to push for a crewed Artemis II flight in 2024 and the return of humans to t.....»»
Zombie deer disease is spreading and scientists are concerned that it could jump to humans
In the tranquil expanses of North America's woodlands and grasslands, a silent but concerning phenomenon is unfolding: chronic wasting disease (CWD). The condition, often dubbed "zombie deer disease", is stealthily spreading among deer populations, s.....»»
