In a few years, the exterior of the International Space Station could be crawling with geckos. It’s not an alien invasion, or the plot of a low- budget sci-fi movie. The robotic geckos could follow from an experiment NASA launched to the International Space Station on Tuesday aboard an uncrewed Cygnus spacecraft . The Gecko Gripper devices use tiny artificial hairs that replicate the ones geckos use to climb walls . They are designed to help astronauts to keep track of objects in zero gravity, and enable robots to crawl around a spacecraft to inspect and repair it. The bots have already been tested on parabolic aircraft flights, where they grabbed and manipulated 10-kilogram and 100-kg objects during 20-second periods of microgravity. On the ISS trip, astronauts will test the system by attaching it to surfaces inside the space station. They will attach five devices in a range of sizes to 30 surfaces at different angles to check how well they grip. The devices wi...

Increased activity in the amygdala -- the fear center of the brain -- appears to create an immune system reaction that increases inflammation in the arteries, researchers plan to report at the upcoming American College of Cardiology meeting in Chicago. Such arterial inflammation is a precursor to heart disease, heart attack and stroke, said senior researcher Dr. Ahmed Tawakol, a cardiologist at Massachusetts General Hospital in Boston. Tawakol and his colleagues followed nearly 300 people and found their amygdala activity -- as seen on brain scans -- indicated whether they would suffer a major cardiac event in the near future. "By the end of the study, roughly 5 percent with low activity had events, compared to roughly 40 percent of the individuals with high amygdala activity," Tawakol said. Doctors need to be aware of the heart-health consequences of current events such as the Syrian crisis and this week's terror attacks in Brussels, said Dr. Rich...

Zanzibar. Police here have promised to escort those wishing to vote in tomorrow’s polls, if the need arises. Urban West Regional Police Commander Mkadam Khamis Mkadam told Kwetu blog on Saturday that security would be maintained. Police officers will be stationed inside polling stations and within 200 metres from the stations, he said. “There are a lot of threats. If anyone wants to vote and thinks his or her life is in danger, he or she can reach us and we will escort the person to the polling station and back home. We have furnished the public with our telephone numbers.” According to him, patrols will be intensified in some areas based on the past election experience. “Some areas are notorious for political violence. We will ensure that everything is contained and based on our preparations it is our hope that the situation will be under control.” Speaking on the arrests of senior officials of opposition Civic United Front (CUF), he said that was in line with pol...

Within all the metal, only gold poured in human economic life and it has such a significant influence to the human society. In the thousands of years of human civilization history, through the years, the up and downs, honor or disgrace, lift uncertain, the social status of gold have never changed and it still the wealth that puersued by all the people. We will give you the key to concentrate the gold from the mineral ore. Gold ore means the mineral ore which is with sufficient Au elements and it is with ndustrial exploitation value. Here is the several common gold ore for your reference as below: 2. The processing technology for the gold ore: Coarse gold ore: a. Gravity Separation+flotation b. Gravity Separation+ CIL processing technology Fine Gold ore or the gold ore with high flotability ( like Sulfide gold and silver, the gold is associated with qurtz) a. Flotation processing b. Flotation+ CIL processing c. CIL processing Gold is in fine-grained or the ...

As mobile and wearable devices such as smartwatches grow smaller, it gets tougher for people to interact with screens the size of a matchbook. That could change with a new sonar technology developed by University of Washington computer scientists and electrical engineers that allows you to interact with mobile devices by writing or gesturing on any nearby surface -- a tabletop, a sheet of paper or even in mid-air. FingerIO tracks fine-grained finger movements by turning a smartphone or smartwatch into an active sonar system using the device's own microphones and speakers. Because sound waves travel through fabric and do not require a line of sight, users can even interact with a phone inside a front pocket or a smartwatch hidden under a sweater sleeve. In a paper to be presented in May at the Association for Computing Machinery's CHI 2016 conference in San Jose, California, the UW team demonstrates that FingerIO can accurately track two-dimensional f...
