Researchers have discovered a gene for a tandem potassium channel in an algal virus. The finding supports the view that giant viruses may have contributed significantly to the evolution of complex proteins. The study is published in the journal Proceedings of the National Academy of Sciences.
Copper is essential for making bronze, which shaped tools, weapons and ornaments across Bronze Age Europe. While many Bronze Age mines have been identified throughout Europe, researchers are still trying to pin down which of them were most active at different times and how far their copper traveled. New research, published in the journal Antiquity, suggests that a series of mines in modern-day Spain and Portugal may have been an important source of copper in the Late Bronze Age, with some of that copper ending up as far away as Scandinavia.
New research in the journal Science finds that crows turn visual information into decisions twice as fast as humans and primates. They also process information is quite similarly to humans.
