An uncannily human-like robot that had been programmed to socially interact with human companions tricked people into thinking that the mindless machine was self-aware, according to a new study.
The digital deceiver, which the researchers dubbed "iCub," is a child-size humanoid robot created by the Italian Institute of Technology (IIT) in Genoa to study social interactions between humans and robots. This advanced android, which stands at 3.6 feet (1.1 meters) tall, has a humanlike face, camera eyes that can maintain eye contact with people and 53 degrees of freedom that allow it to complete complex tasks and mimic human behaviors.

Doctors recently transplanted pig hearts into two deceased patients, raising hopes that animal transplants could one day be used to save human lives.
Led by Dr. Nader Moazami, a cardiac surgeon at NYU Langone Health medical center in New York City, the surgeries took place in June and July, according to the Associated Press. Earlier this year, a different group of doctors from the University of Maryland Medical Center transplanted a pig heart into another patient, who died two months after the operation, Live Science reported in March.
After months of nausea and vomiting, a middle-age man in the United Kingdom finally learned the toxic cause of his health problems: too much vitamin D. His doctors found that an overzealous supplement regimen was to blame.
The patient lost 28 pounds (12.7 kilograms) in three months and complained to his general practitioner of persistent abdominal pain, dry mouth, diarrhea and vomiting, according to a case study published July 6 in the British Medical Journal. At the hospital, doctors learned that the man's symptoms had started about one month after he began an intense vitamin regimen suggested by a private nutritionist.

It was a cold case with hundreds of victims. For decades, scientists puzzled over a gruesome mystery: What killed hundreds of fossilized frogs found at an ancient "death trap" in Germany dating to millions of years ago?
These frogs seemed to be completely healthy when they died, but researchers recently determined that the amphibians may have drowned during aggressive underwater sex.
Is the summer heat getting you down? Cool off with a virtual dip into icy Arctic waters and watch as tens of thousands of beluga whales frolic in the frigid sea. Starting Friday (July 15), the research vessel Delphi will broadcast a beluga whale livestream, direct from the Churchill River estuary where the river flows into Hudson Bay in northeastern Canada.
The livestream, produced in a partnership between Arctic conservation nonprofit Polar Bears International and explore.org, is in celebration of Arctic Sea Ice Day on July 15. The goal is to raise public interest in sea ice and increase awareness of its importance to the Arctic ecosystem.
