Five people have been killed and at least two others wounded in the Kingsessing neighbourhood of Philadelphia on Monday night, when a gunman dressed in a bullet-proof vest and armed with an AR-15-style rifle and a handgun opened fire. The mass shooting unfolded at around 8.30pm when Philadelphia police said the 40-year-old suspect left his home and began shooting at victims. Police initially said that four men were killed but early on Tuesday revealed that a fifth victim, a 31-year-old man, had since been found dead inside a home. Two children – aged two and 13 – were also injured in the shooting but are in stable condition. Responding officers chased the suspect and arrested him on the scene. As well as the weapons, a police scanner was found. The identities of both the suspect and the victims have not been released. While the motive for the massacre remains unknown, Police commissioner Danielle Outlaw said in a press conference that “at this point all we know is that this person decided to leave their home and target individuals”. A second person was also taken into custody with police saying they believe the individual returned fire on the shooter.

Researchers in China have developed an artificial intelligence tool capable of designing a working computer in under five hours. The team of 19 computer scientists from five different institutions made the AI breakthrough after setting out to prove that machines can create computer chips in a similar way to humans. The feat was performed 1,000 times faster than a human team could have achieved it, the researchers claimed, marking a major step towards building self-evolving machines. “Design activity... distinguishes humanity from other animals and traditional machines, and endowing machines with design abilities at the human level or beyond has been a long-term pursuit,” the scientists wrote in a paper detailing their research. “We present a new AI approach to automatically design a central processing unit (CPU), the brain of a computer, and one of the world’s most intricate devices humanity has ever designed.” The project involved the layout of an industrial-scale RISC-V CPU, capable of running the Linux operating system and achieving an accuracy of 99.99 per cent in validation tests. The AI bypassed the manual programming and verification process of the typical design cycle, which the researchers said “consumes more than 60-80 per cent of the design time and resources” of human teams. The AI was also able to autonomously make discoveries involving computer design, uncovering something called the von Neumann architecture, first invented in 1945. The overall performance of the CPU is relatively modest compared to modern computers, with the researchers saying it can perform at a similar level to a 1991 Intel 80486SX CPU. Developing the AI approach, however, has the potential to “reform the semiconductor industry by significantly reducing the design cycle”, the researchers said. The research is detailed in a study, titled ‘Pushing the limits of machine design: Automated CPU design with AI’. Leading AI chip maker Nvidia has previously used artificial intelligence to optimise its computer chip designs, publishing a new approach to AI-powered chip design in March that could significantly improve the cost and performance of CPUs.

Scientists believe they have discovered the cause of the megalodon's extinction – and no, it’s not Jason Statham. Experts have been conducting research on fossils of teeth from the biggest species of shark the world has ever seen, which went extinct around 3.6 million years ago and measured at least 15 metres long. Research published in the journal Proceedings of the National Academy of Sciences explains that the animal was actually partially warm-blooded. Unlike most cold-blood sharks, the body temperature is thought to have been around 27 degrees. The temperature is higher than the sea temperatures around the time. Sign up to our free Indy100 weekly newsletter Study co author Robert Eagle, who is professor of marine science and geobiology at UCLA, said [via CNN]: “We found that O. megalodon had body temperatures significantly elevated compared to other sharks, consistent with it having a degree of internal heat production as modern warm-blooded (endothermic) animals do.” They were able to prove that the animals were warm-blooded by analysing how carbon-13 and oxygen-18 isotopes were closely bonded together in the fossilised teeth. Senior study author Kenshu Shimada is a paleobiologist at DePaul University in Chicago, who said: “A large body promotes efficiency in prey capture with wider spatial coverage, but it requires a lot of energy to maintain. “We know that Megalodon had gigantic cutting teeth used for feeding on marine mammals, such as cetaceans and pinnipeds, based on the fossil record. The new study is consistent with the idea that the evolution of warm-bloodedness was a gateway for the gigantism in Megalodon to keep up with the high metabolic demand.” The fact it was warm-blooded means that regulating body temperature could have been the cause of its eventual demise. The Earth was cooling when the animal went extinct, which could have been a critical factor. “The fact that Megalodon disappeared suggests the likely vulnerability of being warm-blooded because warm-bloodedness requires constant food intake to sustain high metabolism,” Shimada said. “Possibly, there was a shift in the marine ecosystem due to the climatic cooling,” causing the sea level to drop, altering the habitats of the populations of the types of food megalodon fed on such as marine mammals and leading to its extinction. “One of the big implications for this work is that it highlights the vulnerability of large apex predators, such the modern great white shark, to climate change given similarities in their biology with megalodon,” said lead study author Michael Griffiths, professor of environmental science, geochemist and paleoclimatologist at William Paterson University.
