Four planets locked in a perfect rhythm around a nearby star are destined to be pinballed around their solar system when their sun eventually dies, according to a study led by the University of Warwick that peers into its future.

Astronomers have modeled how the change in gravitational forces in the system as a result of the star becoming a white dwarf will cause its planets to fly loose from their orbits and bounce off each other’s gravity, like balls bouncing off a bumper in a game of pinball.

In the process, they will knock nearby debris into their dying sun, offering scientists new insight into how the white dwarfs with polluted atmospheres that we see today originally evolved. The conclusions by astronomers from the University of Warwick and the University of Exeter are published in the Monthly Notices of the Royal Astronomical Society.

The formula for launching a machine learning company in health care looks something like this: Build a model, test it on historical patient data in a computer lab, and then start selling it to hospitals nationwide.

Suchi Saria, director of the machine learning and health care lab at Johns Hopkins University, is taking a different approach. Her company, Bayesian Health, is coming out of stealth mode on Monday by publishing a prospective study on how one of its lead products — an early warning system for sepsis — impacted the care of current patients in real hospitals.

Mint Mobile is an American telecommunications company which sells mobile phone services and operates as an MVNO on T-Mobile’s cellular network in the United States.

BleepingComputer reported that Mint Mobile has disclosed a data breach that exposed subscribers’ account information and ported phone numbers to another carrier.

The data breach notification sent to the impacted subscribers reveals that an unauthorized person gained access to their data between June 8th and June 10th. The company did not reveal how hackers had access to the subscribers’ data.

Following a second exploit in 9 days, over 14 tokens listed on the ChainSwap bridge have plunged 99%. The company insists: funds from individual wallets are safe.


ChainSwap, a cross-chain asset bridge and application smart chain, has become the latest victim of the increasingly worrying exploits happening in the DeFi ecosystem that has caused the sector to lose hundreds of millions of dollars since the start of the year.

What is ChainSwap?

As a hub for smart chains, the ChainSwap protocol acts as a defi bridge for projects and users to seamlessly move assets between different blockchains like Ethereum (ERC20), Binance Smart Chain (BSC), and Huobi’s ECO Chain.

Olympic stadiums can be costly and wasteful. Some have argued for a single, more sustainable, location that can be used year after year.


The summer Olympics have been a quadrennial tradition ever since the late 1800s—when modern sports and rivalries freshened up the ancient tradition. Since COVID-19 crashed the schedule for last years’ events, now the world is gearing up again for another round of competition in Tokyo.

Transporting athletes and fans from all over the world and to cities hosting the Olympic games comes with a gigantic carbon footprint, for example, the 2021 London Olympics had an estimated footprint of over 400 thousand tons of CO2 emissions. Constantly building brand-new stadiums every few years that often go unused after the games, with very few exceptions, is also extremely wasteful. The 2016 Rio Olympics whipped up a whopping 3.6 million tonnes of carbon when including all that went into infrastructure. Eerie listicles of decaying stadiums, including Rio’s, litter the internet with costly examples of the wasted hundreds of millions of dollars worth of labor and materials that go into just one site.

For as long as the games have existed, there have been proponents of having just one Olympic location. King George of Greece gave a speech offering to permanently host the games in the spirit of its origins in 1896, the year of the first modern Olympic games. Some countries, like the United States, agreed, while others, including Pierre de Coubertin who revived the modern Olympics, worried that it would make the games too Hellenistic and that it would hurt the international spirit behind the worldwide event. John Rennie Short, a public policy professor at the University of Maryland, has spoken in the past about the environmental and financial benefits of having the games in a singular location.
