Tesla popularized “invisible” car door handles. China has just handed down its death sentence

In China they have been wanting for a long time ban retractable handles of the vehicles, a design commonly popularized by Tesla. It is no wonder, since over the last few years we have witnessed serious fatal and safety incidents involving this type of handles. The regulations will force many of the best-selling models on the market to be redesigned. what has happened. The Ministry of Industry and Information Technology of China has approved a new safety regulation that will come into force on January 1, 2027. The regulation prohibits door handles recessed in the body and requires that all vehicles have visible handles and a mechanical opening system on each door, according to they count from Financial Times. Why is it important. The hidden handle design has become popular in recent years in electric cars. In China they had been following Tesla’s example for a long time, looking for a more minimalist aesthetic and small aerodynamic improvements. Virtually all of the major electric car manufacturers in China have models with retractable handles. However, these designs have proven to be dangerous in emergency situations. The trigger. A fatal accident in 2024 with Aito’s M7 SUV was one of the main triggers. Three people, including a two-year-old child, died after a crash. Videos shared on social media showed rescue teams breaking windows to try to save victims. As Aito explained in a statement, “the power and signal cables were immediately cut, preventing the handle controller from receiving the ejection signal.” The concern continued after two accidents with the Xiaomi SU7whose videos showed people struggling to open the vehicle doors to rescue those inside, without luck. What the regulations require. Just like they explain from CarNewsChina, the ‘GB 48001-2026’ standard states that each door must have a mechanical exterior handle located in specific areas of the door surface, with sufficient space for manual operation in emergencies such as deployment of restraint systems or battery problems. Electric handles must include independent mechanical mechanisms capable of withstanding forces of at least 500 N. On the other hand, inside, each side door must have at least one mechanical opening handle with graphic symbols of at least 100 mm × 70 mm and clearly visible instructions or pictographic symbols. Impact on the industry. The regulations will affect numerous models from manufacturers such as Xiaomi, BYD and others that have adopted designs similar to Tesla. Bill Russo, founder of Automobility, counted to FT that the standard will require changes to some models but not a complete redesign. “Many manufacturers already design alternative handle solutions for export markets with different regulations,” he explains. “With the new regulation, we will be ready to change any handle as the government wants,” Stella Li, executive vice president of BYD, told Bloomberg TV. Outside China. Perhaps the most notorious case is in the United States, where the issue of hidden handles is also being investigated. The National Highway Traffic Safety Administration opened investigations on Tesla Model Y and Model 3 over concerns about the accessibility of their vehicles in emergencies. A particularly serious accident in California that caused the death of three teenagers in a Cybertruckwhere neither the occupants nor anyone close to the incident could open the doors through the hidden handles and reinforced glass, prompted Congress to take action and Tesla to announce a redesign of its handles.

A simple gene can send a divine punishment to the snails: turn them into “left -handed”

It is estimated that Something more than 10% of the world population is left. Today, this does not usually involve greater inconveniences, but there are animals that have a more problematic asymmetry: snails. Left -handed snails. Most snails share the direction in which their snail draws its spiral characteristic that revolves in the direction of the clock needles. But there is a very small population of snails whose shells develop in reverse. The reason It seems to be In a small genetic variation. The snails that develop their shell symmetrically to the rest are usually called them as “left -handed snails”, but if we had to look for a more precise human analogue we tended to go to the condition to which which We call SITUS INVERSUS. People with this condition, also of genetic origin, develop one or more organs on the “incorrect” side, for example they can have the heart to the right and the liver to the left. This condition occurs in around one person in 10,000 and rarely generates disorders, but in the case of these mollusks, the investment of their snail can cause problems, for example, making it difficult to reproduce these animals. A vital gene. Understanding the genetics responsible for change in these animals is important since it can give us clues about the evolution that was modeling the different genera and gastropod species. According to Explain the team Responsible for discovering the main gene involved in this differentiation, throughout the evolution, these changes resulted in the appearance of new species, something striking when it comes to mutations that hinder reproduction. Laboratory snails. The team conducted its study with a variant of snails of the species Bradybaena Similaris. The variant has the characteristic of presenting a high prevalence of “left -handed” snails, almost half of the specimens are born with this characteristic. The team compared the genes of the mice born with shells that turned to either side. They discovered that the main difference was in a gene, Diaph, but not in the gene itself but in its expression. The details of the study were published In an article In the magazine Zoological Letters. Jeremy’s curious case. Perhaps the most famous snail to present this anomaly was a British snail nicknamed Jeremy in honor of politician Jeremy Corbyn, the leftist politician who was twice a candidate for prime minister in the United Kingdom. Jeremy was the protagonist of another investigation whose results postulated an alternative hypothesis to genetics based. The team responsible for the study concluded, after gathering numerous specimens such as Jeremy so that they could reproduce between them, that the change obeyed external forcesnot by genetic inheritance but for accidents in development. The study, Posted in 2020 In the magazine Biology Lettersreminds us that we will still have to investigate these mollusks, their genetics and their development, if we want to know exactly what phenomenon is behind this unique characteristic of a small amount of snails and, above all, of its implications.
