A new technique is a dramatic breakthrough in the search for alien life, astronomers say. Researchers at the Breakthrough Listen project based at the University of California, Berkeley say they have developed a new way to be sure that any potential signal is really coming from space – and not from something more boring. Astronomers spend vast amounts of time looking for radio signals that might have come from alien civilisations as part of work on the search for extraterrestrial intelligence, or SETI. But they have in the past been fooled by very human technology, such as cellphones, microwaves and car engines, that can produce a blast of radio signals that look as if they have come from distant worlds. One way to check whether signals are really alien is to point the telescope elsewhere and then repeatedly return to the same spot, with the hope of seeing the signal again and ensuring that it is not a false alarm. But that is not foolproof – and only works if the signal sticks around. Some of the most promising radio signals might only be detectable once. The so-called “Wow!” signal, for instance – a radio signal detected in 1977 that was so shocking the astronomer who found it wrote the exclamation on a printout – has not been detected since, and astronomers still do not know whether it was an alien message or just a mistake. Now scientists have devised a new test that can be used to see whether a signal has really passed through interstellar space, which should help show that it is not from elsewhere on Earth. It works by looking for “scintillation” – the changes in amplitude of a signal as it is affected by the cold plasma of space. “The first ET detection may very well be a one-off, where we only see one signal. And if a signal doesn’t repeat, there’s not a lot that we can say about that. And obviously, the most likely explanation for it is radio frequency interference, as is the most likely explanation for the Wow! signal,” said Andrew Siemion, principal investigator for Breakthrough Listen and director of the Berkeley SETI Research Center, which operates the world’s longest running SETI program. “Having this new technique and the instrumentation capable of recording data at sufficient fidelity such that you could see the effect of the interstellar medium, or ISM, is incredibly powerful.” Dr Siemion called the breakthrough “one of the biggest advances in radio SETI in a long time” and said that it would be the first time researchers would be able to differentiate a real signal from a false alarm, even if it was only detected once. The technique can only be used for signals that have travelled 10,000 light years or more to Earth, researchers note. If it was closer to us, the scintillation effect cannot be seen because they are not travelling through enough of the interstellar medium, or ISM. The research is described in a new paper, ‘On Detecting Interstellar Scintillation in Narrowband Radio SETI’, published in The Astrophysical Journal.

In an interview recorded days before lawsuit allegations were made public, Lizzo hinted that something was making her 'sad', prompting speculation she knew of the storm was coming. A pre-recorded 60 Minutes interview has been released, in which producers were totally unaware of what was to come. "Even today, I was having a rough day. I was sad and stuff earlier today", she told host, Tom Steinfort. "And I still feel like for some of reason, even if I'm having a bad day or I'm going through something, people still get good from it. Maybe I'm transmuting it or maybe I'm an alchemist."

MrBeast has confirmed that he is suing the company behind his burgers over quality control complaints, while also claiming not to have received payments. The YouTube star partnered with Virtual Dining Concepts back in 2020 to launch a chain of “ghost kitchens” which would act as “virtual restaurants” producing MrBeast Burgers. MrBeast, real name James Donaldson, is now taking legal action after the virtual chain was hit with complaints from users, Bloomberg reports. The lawsuit refers to the negative feedback from customers, reading: “Customers have referred to the burgers as being ‘disgusting’, ‘revolting,’ and ‘inedible'.” Sign up to our free Indy100 weekly newsletter “There are thousands of negative reviews, articles, and comments from people who are deeply disappointed by the fact that MrBeast would put his name on this product.” It continues: “Because the entire business is based on the tremendous global value of the MrBeast brand, it is MrBeast himself, and not Virtual Dining Concepts, who has borne the brunt of the (justified) attacks and criticisms.” The lawsuit also claims that MrBeast has not received payments. “To be clear, while this business has made millions of dollars, MrBeast has not received a dime,” it claims. MrBeast also responded to a user on Twitter who was unhappy with their experience ordering the burger by saying: “It’s impossible to guarantee the quality of orders with virtual restaurants. Hurts my soul to see orders messed up. Sadly I can’t get out of my deal with [MrBeast Burger]”, he said. “Hence why I’m never giving up control of Feastables so I can always do what’s best for my fans. Harsh lesson to learn.” Links to negative reviews and comments from customers are also included in the lawsuit. Have your say in our news democracy.
