New studies on spider’s silk promise to deliver huge medical benefits in everything from knee replacements to heart transplants.
Researchers in Australia have found evidence that dragonflies are capable of higher-level thought when hunting their prey. This is the first evidence that an invertebrate animal has brain cells capable of selective attention, something that has so far only been demonstrated in primates.
