 Ship to circumnavigate Denmark with passengers, but without crew The Nelly Bly will leave the port of Hamburg next September. On board this small tug will be three people, but none of them will take the controls unless it is an emergency. It is an autonomous boat and its creators want it to circumnavigate Denmark. The crossing is neither short nor easy. It is a route of 1,000 nautical miles (approximately 1852 km) filled with sea traffic of all kinds and with stops at equally busy ports. The promoters of the voyage are an American company called Sea Machines and the aim of the voyage is precisely to test their new autonomous maritime navigation system, the SM300. The SM300 is a computerized vision system that complements GPS guidance systems and all other computerized nautical information enjoyed by human-piloted vessels. The system is not only capable of following a predetermined route. It also detects obstacles and avoids them along that same route. This last detail is critical ...

 Three Russian politicians have the same name and the same face The story takes place in the elections for a municipal seat in St. Petersburg, Russia. There, candidate Boris Vishnevsky was looking like a clear winner until one morning he finds his image next to those of his two rivals wallpapering the entire city. His rivals are also Boris Vishnevsky, and it would seem that they are the same person. Put another way, at first glance it looks like Vishnevsky is running against two people who not only legally changed their names to his, but also borrowed his physical appearance to confuse voters. What? Yes, and apparently it's nothing new that Russian opposition politicians are used to running against candidates with the same last name. In fact, it's a common tactic with the idea of derailing a few votes in close elections. Local media reports say that Vishnevsky, a senior member of the liberal Yabloko party running for public office in a St. Petersburg district, already knew that...

 Scientists Are Toilet Training Cows To Reduce Emissions Researchers in Germany recently demonstrated that cattle can learn to go to the bathroom to reduce some of their climate impact. By making young cows urinate in latrines made of grass, the team of animal behavior and agricultural science experts stopped the natural production of nitrous oxide caused by cow urine. Cows are notorious for their contributions to greenhouse gas emissions in large-scale agriculture; the animals burp (and to a lesser extent, fart) methane, and their urine and feces combine to produce ammonia, which is not itself a greenhouse gas, but is converted to nitrous oxide by soil microbes. The team trained nearly a dozen calves to urinate in a makeshift latrine, dubbed MooLoo, thus preventing the urine from becoming part of the problem. The research was published Monday in Current Biology . "It is generally assumed that cattle are not capable of controlling defecation or urination," Jan Langbein, an a...

 How do fish sleep? We have probably all asked this question at least once in our lives. Most of us, usually during our childhood, have had fish as pets, however, although we have tried to observe them sleeping, we have not obtained the answers we expected... But of course, the word sleeping does not exactly define their resting period. It seems that fish do not sleep since, apparently, they are always with their eyes open. But the simple fact that fish do not have eyelids does not mean that they do not sleep. Like any living being, they also need a rest time, as all animals respond to the time and stationary cycles of this planet. They sleep in their own way, motionless at the bottom of rivers, seas or aquariums. They slow their heart rate and completely suspend any movement to achieve something like a short hibernation. They have a transparent membrane that covers their eyes, preventing the dim light of the night from disturbing their "sleep". Something like our eyelids. Fi...

 "Upgrading the RAM" of some Samsung phones is now possible with an update Samsung has joined the mobile virtual memory craze with a new feature called "RAM Plus". RAM Plus is a software upgrade that, for all practical purposes, expands the amount of RAM available on the phone by making use of a portion of the ROM memory, which is normally used for storage. According to SamMobile , RAM Plus has been implemented first on the new Galaxy A52s 5G, starting with those in India. The feature, which comes in firmware update A528BXXU1AUH9, allows you to add up to 4GB of virtual memory to the phone (which itself already has 6GB of physical RAM). Samsung is the latest manufacturer to incorporate a virtual memory feature to its handsets after Xiaomi, Vivo, Oppo and Realme. Oppo plans to expand by up to 7GB the RAM of its phones with its own software update, for now available in the Middle East and Africa. But don't expect a drastic change in phone speed. RAM is extremely fa...

 Singapore police to use robots to search for "undesirable social behavior" If you're wandering around Singapore soon, don't forget to say hello to this friendly (and snitchy) neighborhood robot. Singapore's Home Team Science and Technology Agency (HTX) will deploy two robots called "Xavier" that, according to the agency, use cameras with a 360-degree field of view and analytics software to detect "undesirable social behaviors" in real time. As Business Insider reported , the robots are designed to detect activities such as smoking in public, violation of pandemic restrictions (i.e., groups of more than five people) and illegal street vending. Other behaviors the agency said the robots can detect include the use of motorized vehicles or motorcycles in pedestrian walkways and "improperly parked bicycles." The Xavier robots travel a "patrol route preconfigured in advance by public officials," although they can deviate as need...
