GameStop Offers to Buy eBay for $56 Billion

GameStop has made an unsolicited $56 billion cash-and-stock offer to buy eBay (paywalled; alternative source), with CEO Ryan Cohen arguing he can turn the marketplace into a far larger Amazon competitor. "EBay should be worth -- and will be worth -- a lot more money," Cohen said in an interview. "I'm thinking about turning eBay into something worth hundreds of billions of dollars." The Wall Street Journal reports: Cohen said GameStop has a commitment letter from TD Bank to provide up to $20 billion in debt financing to help make a deal possible. GameStop delivered an offer letter to eBay on Sunday and released a copy of it following the Journal's report on the details of the bid. Cohen wrote in the letter to eBay Chairman Paul Pressler that GameStop started building its eBay position on Feb. 4. It said its offer consists of 50% cash and 50% GameStop shares. EBay said Monday morning its board and financial advisers would review GameStop's unsolicited proposal. It said there were no discussions with or outreach from GameStop before receiving the offer. Ebay added that it will review the offer "with a focus on the value to be delivered to eBay shareholders, including the value of the GameStop stock consideration and the ability of GameStop to deliver a binding, actionable proposal." If eBay isn't receptive, Cohen said he was prepared to run a proxy fight and take the offer directly to its shareholders. The window for shareholders to nominate director candidates at eBay ahead of an annual meeting scheduled for this June has already closed, according to the company's proxy materials. Cohen told the Journal that putting his videogame retailer and eBay under one roof could create opportunities to cut costs and improve earnings. The two companies have some overlap already, including a focus on selling collectibles such as trading cards. "There is nobody who is more qualified, based on my experience, to run the eBay business," Cohen said, referencing his time at GameStop and previously Chewy, the online pet-products marketplace he co-founded.

Scientists Discover 27 Potential New Planets That Orbit Two Stars

Astronomers have identified 27 potential new circumbinary planets -- worlds that orbit two stars, like Star Wars' Tatooine. "To date, only about 18 circumbinary planets ... had been identified in the universe," reports the Guardian. "More than 6,000 planets have been discovered that orbit single stars, like Earth does around the sun." The Guardian reports: In a timely publication for May 4, also known as Star Wars Day, scientists have identified nearly 30 more candidate planets, whose distances range from 650 to 18,000 light years away from Earth. [...] More than half of the stars in the universe exist in binary or multiple star systems. The researchers instead used a method known as "apsidal precession," searching for a wobble between stars that orbit around and eclipse each other. "If we monitor the exact timing of these eclipses ... that can tell us that there's something else going on in the system," said Margo Thornton, the study's lead author and a PhD candidate at UNSW. After eliminating other factors such as the rotation and gravitational pull of the two stars, the team identified 36 star systems out of 1,590 whose behavior could only be explained by a third body. For "27 of those objects, it is possible that they are planet mass," Thornton said. More research into their spectra -- the light they emit -- was needed to formally confirm them as circumbinary planets, she said. "It's just a matter of: what is the mass of it? Is it a planet? Is it a brown dwarf? Is it a star?" The team discovered the potential planets -- which likely range from Neptune-sized to ten times heavier than Jupiter -- using data from Nasa's Transiting Exoplanet Survey Satellite, a planet-hunting space telescope that launched in 2018. The research was published in the Monthly Notices of the Royal Astronomical Society.

Infrasound Waves Stop Kitchen Fires, But Can They Replace Sprinklers?

An anonymous reader quotes a report from Ars Technica: In a makeshift demonstration kitchen in Concord, California, cooking oil splatters in and around a frying pan, which catches fire on an unattended gas stove. Within moments, a smoke detector wails. But in this demonstration, something less common happens: An AI-driven sensor activates and wall emitters blast infrasound waves toward the source of the fire in an attempt to put it out. The science of acoustic fire suppression, which has long been known and documented in scientific literature and the press, works by vibrating oxygen molecules away from a fuel source, depriving the fire of a critical component needed for combustion. Indeed, after just a few seconds of infrasound, the tiny kitchen blaze goes out. "We were able to not just point-and-shoot like a fire extinguisher; we figured out how to run it through ducting and distribute it like a sprinkler system," said Geoff Bruder, co-founder and CEO of Sonic Fire Tech, during the presentation. The company's goal is to replace sprinklers, which are effective at stopping fires but can also do significant water damage to a property. Sonic Fire Tech appears to be the first company trying to commercialize the science of acoustic fire suppression. Its executives have already been touring Southern California; Wednesday's event was the first in the northern half of the state. The company aims to make this infrasound technique mainstream in both commercial (for instance, a data center, where sprinklers would damage electronics) and in-home installations, given that sprinklers are already required in all new California homes built in 2011 and later. Sonic Fire Tech also hopes to produce a backpack-based system that could be worn by wildland firefighters headed out into the field. "We are making meaningful technological improvements on a monthly basis," Stefan Pollack, a company spokesperson, emailed Ars after the event. But two experts who spoke with Ars raised serious questions about the potential for this technology to supplant traditional sprinklers in a home. They are even more skeptical as to whether the technique can be effective in an uncontrolled wildfire situation, where flames can grow very quickly. Experts are concerned that infrasound may knock down small flames but does not cool hot surfaces or wet fuel like sprinklers do, which raises the risk of re-ignition, smoldering fires, hidden fires, or blocked fires. Sonic Fire Tech has claimed third-party validation and possible NFPA 13D equivalency, but it has not publicly released full testing details. Fire officials and outside observers also want more information about reliability, maintenance, calibration, and how system failures would be detected and communicated.
