CHATGPT'S MEMORY CAN NOW REFERENCE ALL PAST CONVERSATIONS, NOT JUST WHAT YOU TELL IT TO

OpenAI is rolling out improvements to ChatGPT's memory and making it a default for the chatbot to reference past conversations. The chatbot will now draw on past conversations to deliver more relevant and useful responses across all modalities on the platform. While AI long term memory could be useful for many tasks, some users are concerned with the privacy implications of the feature. Users are able to turn the feature on or off in ChatGPT settings.

TARIFFS, TRADE TENSIONS MAY BE POSITIVE FOR BITCOIN ADOPTION

Tariffs may lead to stagflation, reducing the appeal of traditional assets and boosting demand for inflation-resistant stores of value like Bitcoin. As economic pressures mount and the U.S. dollar's reserve dominance potentially wanes, Bitcoin adoption is expected to grow, especially if policy shifts support alternative hedging strategies.

GOOGLE PIXEL 9A REVIEW: ALL THE PHONE YOU NEED

Google's new Pixel 9a has most of what makes flagship Pixel phones so good at a $499 price point. While the cheaper price point means a trade-off in materials, charging, and the on-device AI capabilities the device has compared to its pricier siblings, none of those are deal-breakers. The modestly-priced phone, which will have lengthy support, could be the perfect purchase in a period of uncertainty for imported gadgets.

NEUTRINOS ARE SHRINKING, AND THAT'S A GOOD THING FOR PHYSICS

A new study published in the journal Science sets a new upper limit for the mass of a neutrino. Neutrinos are prolific across the cosmos - they are created virtually anytime atomic nuclei snap together or rip apart. They carry no electric charge and are notoriously difficult to detect. Learning more about neutrinos will help cosmologists fill in more knowledge about the universe, including how galaxies clustered together and what influences the expansion of the cosmos. Uncovering the exact values of the mass of neutrinos could lead to new physics.

CELLS ARE SWAPPING THEIR MITOCHONDRIA. WHAT DOES THIS MEAN FOR OUR HEALTH?

Mitochondrial transfer - when mitochondria skip from cell to cell on demand - has been observed in a wide variety of cells and in organisms as diverse as yeast, molluscs, and rodents. It isn't clear yet why mitochondria are so mobile, but there are hints that cells donate their mitochondria to neighbors during times of need. The implications for human health are still a mystery. It is unclear whether mitochondrial transfer happens inside the human body.

.LOCALHOST DOMAINS

It's possible to configure private, custom domains for local webapps, so instead of having to remember and type 'localhost:4333', you can simply navigate to 'appname.localhost'. The process involves setting up each app as a launchd daemon that listens to a unique port, configuring /etc/hosts to redirect traffic to 127.0.0.1, and then redirecting traffic from 127.0.0.1 to the right port for the domain. This post provides more details on the process.
