WHY APPLE STILL HASN'T CRACKED AI

While Apple has rolled out new AI features just like its competitors, they've mostly been notable for being delayed and underwhelming. The company announced Apple Intelligence last June, but some of the features are still being delayed - the new Siri won't be out in time for next month's WWDC, a year after it was first announced. Apple has devoted considerable resources to the technology and has little to show for it. While some attribute the struggles to decisions made by executives, others see symptoms of a deeper problem within the company.

OPENAI INTRODUCES CODEX, ITS FIRST FULL-FLEDGED AI AGENT FOR CODING

OpenAI's Codex is an agentic coding tool that allows experienced developers to delegate rote and relatively simple programming tasks to an AI agent to generate production-ready code. It is a unique interface that can be accessed from the sidebar in the ChatGPT web app. Developers can include an 'AGENTS.md' file to give the agent custom instructions. Codex is built on a fine-tuned variation of OpenAI's o3 reasoning model. It is now rolling out to ChatGPT Pro, Enterprise, and Team users - Plus and Edu support will come at a later date.

LASER-POWERED FUSION EXPERIMENT MORE THAN DOUBLES ITS POWER OUTPUT

The team at the US Department of Energy's National Ignition Facility has increased the yield of its net-positive fusion experiment to 8.6 megajoules. They made history in 2022 when they generated 3.15 megajoules in the first controlled fusion reaction to generate more energy than it consumed. While none of the experiments have been effective enough to feed electrons back to the grid, they show that controlled nuclear fusion is more than hypothetical.

FDA OKS FIRST BLOOD TEST THAT CAN HELP DIAGNOSE ALZHEIMER'S DISEASE

A blood test has been approved by US health officials for diagnosing Alzheimer's in patients 55 and older who are showing early signs of the disease. The test identifies a key marker for Alzheimer's, beta-amyloid. The low costs and convenience of the blood test may help expand the use of drugs shown to slightly slow the progression of the disease. Previously, the only FDA-approved methods for detecting beta-amyloid were invasive tests of spinal fluid or expensive PET scans.

GOOGLE IS ABOUT TO UNLEASH GEMINI NANO'S POWER FOR THIRD-PARTY ANDROID APPS

Google's new ML Kit GenAI APIs, likely to be announced at I/O 2025, will enable developers to implement AI features like text summarization into their apps. The APIs will support image input and be available on a wide range of Android devices beyond the Pixel 9 series. They will enable on-device execution of AI foundation models like Gemini Nano to enhance app functionality, keeping user data private by processing data locally.

HOW TO HAVE THE BROWSER PICK A CONTRASTING COLOR IN CSS

CSS' contrast-color() allows the browser to automatically assign contrasting color values. This can be handy, especially in large projects, as managing such small details can be a really hard task to get right. Developers just need to define one color. This post provides a guide on how to use contrast-color() and discusses accessibility considerations when using the function.

GOOGLE I/O 2025: WHAT TO EXPECT, INCLUDING UPDATES TO GEMINI AND ANDROID 16

Google I/O is scheduled for May 20 to 21 at the Shoreline Amphitheater in Mountain View. The developer conference will showcase product announcements from across Google's portfolio, including Android, Chrome, Search, YouTube, and Gemini. It will likely reveal more about Android 16 and spotlight the capabilities in the latest versions of Android XR and Wear OS. Leaks over the past few weeks suggest that an updated Gemini Ultra model is on the way, which may indicate a pricier Gemini subscription.

APPLE SAYS IT WON'T YET ‘TAKE ACTION' ON FORTNITE RETURN TO THE APP STORE
