Fossils in the ‘Cradle of Humankind’ may be more than a million years older than previously thought

For decades, scientists have studied these fossils of early human ancestors and their long-lost relatives. Now, a dating method developed by geologists just pushed the age of some of these fossils found at the site of Sterkfontein Caves back more than a million years. This would make them older than Dinkinesh, also called Lucy, the …

Artificial photosynthesis can produce food without sunshine

Scientists have found a way to bypass the need for biological photosynthesis altogether and create food independent of sunlight by using artificial photosynthesis. The technology uses a two-step electrocatalytic process to convert carbon dioxide, electricity, and water into acetate. Food-producing organisms then consume acetate in the dark to grow. The hybrid organic-inorganic system could increase …

Secrets of aging revealed in largest study on longevity, aging in reptiles and amphibians

An international team of 114 scientists reports the most comprehensive study of aging and longevity to date of reptiles and amphibians worldwide. Among their many findings, they document for the first time that turtles, crocodilians and salamanders have particularly low aging rates and extended lifespans for their sizes. The team also finds that protective phenotypes, …

The heat is on: Traces of fire uncovered dating back at least 800,000 years

Scientists reveal an advanced, innovative method that they have developed and used to detect nonvisual traces of fire dating back at least 800,000 years — one of the earliest known pieces of evidence for the use of fire. The newly developed technique may provide a push toward a more scientific, data-driven type of archaeology, but …
