For years now, brain-computer interfaces (BCI) have incrementally advanced, giving people with spinal injuries or lost limbs the ability to control prosthetics and computer cursors using their signals. But even though the tech has made strides, the replicating subtle, delicate, nuanced sensations of touch has remained just out of reach. Now, however, a team of researchers from the Cortical Bionics Research Group believe they have made a major breakthrough. A pair of patients wearing a BCI was able to control a bionic arm and "feel" tactile edges, shapes, and curvatures along its fingers. The researchers' findings were published today in the journal Science.

Before he died, eccentric philosopher Jeremy Bentham asked that his body be stuffed and wheeled out at parties to help his friends with their grief. But the social reformer didn't stop there, bequeathing 26 memorial rings to those he knew and admired, featuring his bust in silhouette and strands of his hair. Now scientists are on the hunt for Bentham's rings, of which just six have been found since his death in 1832. The philosopher commissioned the rings a decade before he passed, leaving them in his will and testament to a list that included famous politicians, journalists, fellow philosophers and several of his servants. Researchers say the missing artefacts could be spread across the globe, after one was found in a jewellery shop in New Orleans.

Bank phone trees are dreadful experiences, so many banks are turning to chatbots in the hope to spruce up the experience. Take Capital One's chatbot text message "Eno" ("One" backwards), which allows customers to text to get balance, transaction history and pay bills. Customers can even communicate with emojis -- a "thumbs up" means to confirm and a "money bag" will prompt Eno to list a customer's account balance. Capital One's approach to Eno may offer some clues why traditionally risk-averse banks are just taking baby steps. Capital One is only rolling out the product as a pilot for the time being, and the bank is careful to manage future expectations.

San Diego Brayan Valle was looking to buy some marijuana. When he reached out to a business associate of his uncle's, a drug connection, Valle became involved in a much more serious -- and novel -- offense. Rather than sell him the marijuana, the associate asked for Valle's help to smuggle drugs over the U.S.-Mexico border by drone. The case signals the first drone drug-smuggling seizure along the Southwest border. On Thursday, Valle, now 21, was sentenced to three years in prison for his role in operating the drone remote control and loading up 30 pounds of heroin dropped into a Calexico-area field on April 28.
