episode 221: Weekly: Security risks of ChatGPT; do other mammals go through the menopause?; record breaking quantum computer
#221
Independent researchers have found new ways that OpenAI’s ChatGPT tool can assist bad actors, from providing the code needed to hack computer databases to teaching people how to make homemade explosives. While the company continually updates security safeguards, it turns out some languages can be used to bypass these guardrails.
It has long been thought that only humans and some toothed whales go through the menopause. But are there other mammals out there who experience it too? And if so, is it a rarity, or much more common than we realised? The answer may depend on how you define “menopause.”
A US start-up has broken a record in quantum computing, fitting the largest ever number of qubits – or quantum bits – into its new machine, finally exceeding the 1000-qubit milestone and more than doubling the previous record. Qubits are what allow quantum computers to do their calculations, and are essential in increasing reliability and stability. Still, more qubits aren’t the only step in the quest for more practical quantum computers.
Measuring self-awareness in animals usually involves a well-known mirror test, where an animal is given a mark before being placed in front of a mirror. If they touch the mark after seeing it on their reflection, they pass the test. But few animals have passed, and it isn’t without controversy. Now, researchers using a new kind of mirror test to investigate self-awareness in chickens – who fail the classic mirror test – think they have found new evidence that the birds recognise their reflections as “self.” This might reveal self-awareness in a greater variety of animals.
