A largely 3D-printed robotic hand that can translate printed text into finger-spelling is the first stage in a project that aims to produce a fully functional two-armed robot with a face that can handle the full complexity of sign language. It's the project of a team at Belgium's University of Antwerp using a very basic printer to produce the 25 plastic parts of the hand, which also consists of an Arduino Due microcomputer, 16 servo motors, three motor controllers and some additional electronic components.
The absence of gravity in space can be a huge problem for astronauts, who stand to lose as much as 20% of their muscle mass in as little as five days of weightlessness. A team at Ohio State University is working to find solutions by taking successive snapshots of muscle cells on a space flight to judge how fibers change at various points in time.
Singapore University of Technology and Design researchers have developed a new malaria diagnostic test that is portable, cost-efficient and can produce results within half a minute. The improved cytometer has a color camera and raised lens and counts cells by using machine-learning algorithms and image processing.
The USS John S. McCain carried out a routine operation near Mischief Reef in the South China Sea last Thursday, in the process skirting a Chinese artificial island in disputed waters. It was not clear whether the Chinese asked that the destroyer leave the area.
The 6,000-ton icebreaker CCGS Amundsen makes quite an impression as it plows through thick Arctic ice on its mission of research into changing weather patterns and their effect across the Northwest Passage. The project includes the gathering of ancient mud as well as water samples, although the massive vessel may be called to rescue duty at any moment.
More than 60 UK sailors and marines have been training to develop carrier skills aboard the USS George H.W. Bush, which met up with the HMS Queen Elizabeth last week off the Scottish coast. The Royal Navy thanked the US Navy for access to the Bush strike group for exercises intended to prepare for the UK carrier's entry into service this year.
For the second time in a week, an Iranian drone buzzed the USS Nimitz while the carrier was in international waters in the Persian Gulf. The Navy labeled the incident potentially dangerous, and Lt. Ian M. McConnaughey said, "This type of behavior is not in accordance with international maritime customs, norms and laws."
Performance during 270 days on three strategic patrols last year earned the USS Alaska the Omaha Trophy for Best Ballistic Missile Submarine. The Alaska crew also experienced the longest continuous alert period of any unit originating from Kings Bay in the past four years.
The laser technology used in the Navy's new Laser Weapon System is a direct descendant of technology intended for old-fashioned telephones. Key advances that led from communications to powerful but compact laser weaponry lay in the development of fiber optics and inexpensive laser diodes, Robert Afzal of Lockheed Martin explains.
Two former nuclear missile submarines converted to land attack roles with cruise missiles are likely to be at the forefront in any potential confrontation with North Korea. The USS Ohio and USS Michigan are forward deployed to Guam for a year at a time but are based at Naval Base Kitsap.
