Online spending during this year's 48-hour Amazon Prime Day event was up 11% year-over-year, with customers spending $14.2 billion.

WHAM! NUCLEAR FUSION EXPERIMENT HITS NEW RECORD FOR MAGNET STRENGTH

A new fusion experiment has set a record for the strongest steady magnetic field confining a plasma. Strong magnets are essential for certain types of fusion power - for every doubling of the strength of a magnetic field, the power output of one reactor design increases 16-fold. The team was able to produce a 17 tesla magnetic field, more than twice as powerful as the high-resolution MRI scanners used to image human brains. They are now working on more advanced magnet designs.

A SCIENTIST TOOK A PSYCHEDELIC DRUG — AND WATCHED HIS OWN BRAIN 'FALL APART'

A study on psilocybin suggests that psychedelic drugs work by disrupting certain brain networks, especially one that helps people form a sense of space, time, and self. The study, which involved scanning participants' brains with an MRI while under the influence of the drug, showed that the drug caused populations of neurons usually in synchrony to fall out of synchrony. The brain appears to respond to this by entering a state of enhanced plasticity that can last for weeks. The study hints at how psychedelic drugs could be used to treat people with addiction, depression, or post-traumatic stress.

GOTCHAS WITH SQLITE IN PRODUCTION

SQLite provides lower operational complexity. It is the best choice for getting applications running on a single machine. However, SQLite becomes less appealing if a project requires multiple machines, has a write-heavy workload, or has long-running transactions. In these cases, developers are better off using a more traditional database like MySQL or Postgres.

PYTHON GRAPPLES WITH APPLE APP STORE REJECTIONS

Apple's macOS App Store is automatically rejecting apps that contain the string 'itms-services' - the URL scheme for apps to ask Apple's iTunes Store to install another app. The string exists in the urllib parser in Python's standard library. The discovery of this issue led to a discussion among Python developers about whether 'acceptable to app stores' should be a design goal for CPython. The developers decided to implement a `--with-app-store-compliance` configuration option to remove the problematic code.

APPLE TV+ WILL SOON GET A LOT MORE MOVIES MADE BY STUDIOS OTHER THAN APPLE

Apple is in talks with major studios to bring more movies to Apple TV+, expanding and extending the service's appeal. The company's previous experiments with licensing movies and making them available for limited runs seem to have gone well. While Apple has found some success in terms of series, it has struggled to make as much of an impact with its movies. Apple TV+ accounted for $23.9 billion, more than half the revenue generated by iPhone hardware sales, in the second quarter of this year.
