The ancient Incan sanctuary of Machu Picchu is considered one of humanity's greatest architectural achievements. Built in a remote Andean setting atop a narrow ridge high above a precipitous river canyon, the site is renowned for its perfect integration with the spectacular landscape. But the sanctuary's location has long puzzled scientists: Why did the Incas build their masterpiece in such an inaccessible place?
Mosasaurs were true sea monsters of late Cretaceous seas. These marine lizards — related to modern snakes and monitor lizards — grew as long as fifty feet, flashed two rows of sharp teeth, and shredded their victims with enormous, powerful jaws.
If children are exposed to bias against one person, will they develop a bias against that person's entire group? The answer is yes, according to new research.

Researchers have developed a tiny nanolaser that can function inside of living tissues without harming them.
Findings from an innovative new study reveal that the way in which human fungal pathogens form colonies can significantly impact their ability to cause disease. Understanding how these colonies form could lead to new therapies that target these infections in critically ill patients.
Read moreA new imaging study of the mummified arteries of people who lived thousands of years ago revealed that their arteries were more clogged than originally thought, according to a proof-of-concept study.
Read moreResearchers have found that dogs can suffer from the same type of autoimmune encephalitis that people do. The finding could lead to better screening methods for diagnosis and possibly more effective treatments for canine encephalitis.
Read moreResearchers have constructed a quantum-mechanical state in which the colors of three photons are entangled with each other. The state is a special combination, called a W state, that retains some entanglement even if one of the three photons is lost, which makes it useful for quantum communication. Such entangled states also enable novel quantum applications and tests of fundamental physics.
Read moreWhat does it take for a human to trust a robot? That is what researchers are uncovering in a new study into how humans and robots work together. Research into human-agent teaming, or HAT, has examined how the transparency of agents — such as robots, unmanned vehicles or software agents — influences human trust, task performance, workload and perceptions of the agent.
