 "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).

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...

 Wasps are building fluorescent nests A team of scientists say they have come across the first known case of animals building fluorescent houses. In a new study, they detail the finding of nests built by certain species of wasps that glow green under exposure to ultraviolet light. What's more, wasps of the same family in other parts of the world also appear capable of creating similarly creepy structures. The discovery occurred during an expedition to northern Vietnam, but not intentionally, according to the scientists. Study author Bernd Schöllhorn, a professor of chemistry at the University of Paris, told Live Science that they traveled with ultraviolet lights in the hope of stumbling upon any fluorescent bugs after dark. Instead, they found wasp nests with cocoons (woven silk structures that cover the nest and keep the larvae safe) that emitted a bright mucus-green glow when exposed to ultraviolet light between 360 and 400 nanometers wavelength at night. Like any good researche...

 Hum: the smallest city in the world In the northwest of Croatia is located Hum, a town with only 25 inhabitants. According to Guinness World Records, Hum is the smallest city in the world. It is unusual for an urban center with such a small population and land area to be considered a city. In most countries of the world this would never be accepted, but in Croatian territory it is a curious reality. Hum's origins date back to the 11th century, and both the architecture and layout of the city have evolved little since then. It was originally built as a medieval castle with the intention of future urban development. And to some extent, this happened only within the city walls. From medieval castle to Croatian city. Today, a person on foot can walk through the entire city in less than an hour. Although urban development came out of the castle walls, it is just a parking lot and a souvenir store. Inside the walls the town still exists, although with little commercial activity. Fortuna...

 Do you prefer dogs or cats? The answer says a lot about you When it comes to pets, are you a dog lover or a cat lover? The answer to this millennial question could reveal interesting aspects of your personality. Several research studies have focused on deciphering the personality traits that distinguish each group. For example, from a demographic perspective, there are notable differences between people who prefer dogs or cats. Dogs or cats? Mikel Delgado, a researcher and animal behaviorist at the UC Davis School of Veterinary Medicine, conducted a study in 2015 where she analyzed the personality of those who preferred one species or the other. She also took into account people who confessed to having no preference or simply disliked dogs and cats. Under the term "Big 5", Delgado encompassed the personality metrics employed by his research. These are agreeableness, conscientiousness, openness, extroversion and neuroticism. In this context, the latter trait is defined as ner...

 Urban rats are getting bigger and bigger Urban rats do not stop growing, they are longer and fatter compared to other rodents. It is a strange phenomenon that defies Bergmann's rule, which postulates that animals grow smaller the higher the temperature of the environment they inhabit. If you go to great lengths to avoid coming face to face with a huge rat, we have bad news. Although most of the time they are out of sight, or we prefer to ignore them, the situation can change. These rodents, ancient companions of urban life, are growing like never before. A group of researchers from the Florida Museum of Natural History was surprised to conclude a recent study . They found that these mammals are growing beyond what anyone could have predicted. The scientists analyzed the evolution of 140,000 measurements in more than a hundred mammals in North America over eight decades. Rats getting bigger and bigger. Roughly speaking, they found that urban rats are much longer and fatter than tho...
