![]() One promising approach to improving the skills of AI is to expand its senses currently AI with computer vision or audio recognition can sense things but cannot “talk” about what it sees and hears using natural-language algorithms. They lack the human ability, found even in young children, to learn how the world works and apply that general knowledge to new situations. James Temple describes how a lithium-metal battery works, and why scientists are so excited by recent results.ĭespite the immense progress in artificial intelligence in recent years, AI and robots are still dumb in many ways, especially when it comes to solving new problems or navigating unfamiliar environments. But if QuantumScape and others working on lithium-metal batteries succeed, it could finally make EVs attractive to millions of consumers. The battery is still just a prototype that’s much smaller than one needed for a car. The startup has a deal with VW, which says it will be selling EVs with the new type of battery by 2025. According to early test results, the battery could boost the range of an EV by 80% and can be rapidly recharged. It’s called a lithium-metal battery and is being developed by QuantumScape. A well-funded Silicon Valley startup now says it has a battery that will make electric vehicles far more palatable for the mass consumer. ![]() All these drawbacks have to do with the limitations of lithium-ion batteries. Antonio Regalado explains the history and medical potential of the exciting new science of messenger RNA.Įlectric vehicles come with a tough sales pitch they’re relatively expensive, and you can drive them only a few hundred miles before they need to recharge-which takes far longer than stopping for gas. Also in the works: using mRNA to help the body fight off cancers. Messenger RNA also holds great promise as the basis for cheap gene fixes to sickle-cell disease and HIV. And if this coronavirus keeps mutating, mRNA vaccines can be easily and quickly modified. ![]() The new covid vaccines are based on a technology never before used in therapeutics, and it could transform medicine, leading to vaccines against various infectious diseases, including malaria. When the covid-19 pandemic began last January, scientists at several biotech companies were quick to turn to mRNA as a way to create potential vaccines in late December 2020, at a time when more than 1.5 million had died from covid-19 worldwide, the vaccines were approved in the US, marking the beginning of the end of the pandemic. The two most effective vaccines against the coronavirus are based on messenger RNA, a technology that has been in the works for 20 years.
