ALPHABET'S ISOMORPHIC LABS HAS GRAND AMBITIONS TO ‘SOLVE ALL DISEASES' WITH AI. NOW, IT'S GEARING UP FOR ITS FIRST HUMAN TRIALS

Isomorphic Labs, Alphabet's secretive drug discovery arm, is preparing to launch human trials of AI-designed drugs. The company was born from one of DeepMind's most celebrated breakthroughs, AlphaFold, an AI system capable of predicting protein structures and interactions with a high level of accuracy. The system has helped researchers design medicines faster and more precisely.

UNCOMMON USES OF PYTHON IN COMMONLY USED LIBRARIES

Common Python libraries often use Python in uncommon ways. `super()` in Python base classes is often used for cooperative multiple inheritance, and mixins are strategically applied for modularizing optional features. Relative imports are used for correct package resolution, and the `__init__.py` file doesn't always have the same purpose across packages.

COLUMBIA UNIVERSITY STUDENT DATA STOLEN BY POLITICALLY MOTIVATED HACKER

A politically motivated hacker recently breached Columbia University's systems, locking students out of their coursework, email accounts, and video conferencing services. The hacker also stole around 460GB of data, some of which they provided to Bloomberg to showcase that the university employed discriminatory admissions practices. The data includes the Social Security Numbers of students, faculty, staff, applicants, and their families, as well as university ID numbers, citizenship status, admissions decisions, and the program to which they applied.

STAND WITH CRYPTO BACKS CLARITY ACT

Stand With Crypto, backed by Coinbase and joined by 65+ organizations, is urging the U.S. House to pass the Digital Asset Market Clarity Act, which would define SEC and CFTC roles, mandate disclosures, and provide long-awaited regulatory clarity. The bill faces political friction tied to Trump's crypto ventures, with lawmakers racing to finalize legislation before the September deadline.

JACK DORSEY LAUNCHES A WHATSAPP MESSAGING RIVAL BUILT ON BLUETOOTH

Bitchat is a decentralized, peer-to-peer messaging app that works entirely over Bluetooth mesh networks - no internet, central servers, phone numbers, or emails required. It enables ephemeral, encrypted communication - nearby devices form clusters and pass messages from device to device, allowing them to reach peers beyond standard range, even without Wi-Fi or cell service. Messages are stored only on-device, disappear by default, and never touch centralized infrastructure. A beta version of Bitchat is currently live on TestFlight.

CREATING THERAPEUTIC ABUNDANCE

The invention of new medicines is limited by our knowledge of cells and molecules that can be manipulated to treat disease. The cost of discovering new medicines is increasing. New technologies have the potential to unlock an era of target abundance and reverse the long decline in research and development productivity. This could be one of AI's most important impacts.

NUCLEAR REACTORS SMALLER THAN A SEMI TRUCK TO BE TESTED IN IDAHO

The US Department of Energy (DoE) has conditionally selected Westinghouse's trailer-sized eVinci test reactor and Radiant's Kaleidos unit to conduct the first fueled microreactor experiments at its Demonstration of Microreactor Experiments (DOME) facility at Idaho National Laboratory. The DOME project considers anything under 50 MW of power to be a microreactor - the eVinci is designed to produce 5 megawatts, and the Kaleidos can output 1.2 megawatts. The DoE hopes that microreactors can be used to power small, remote sites. DOME is designed to be up and running by early 2026. It will operate one experiment at a time for six months.

HANDLING UNIQUE INDEXES ON LARGE DATA IN POSTGRESQL

PostgreSQL has a limitation on unique index entries larger than 1/3 of a buffer page. The 1/3 page size limit exists to ensure efficient page splitting. To overcome the restriction, introduce a new field that stores a hash of the large field. This allows you to store really large data inside databases, even with unique constraints.
