APPLE TAKES CONTROL OF ALL CORE CHIPS IN IPHONE AIR WITH NEW ARCHITECTURE TO PRIORITIZE AI

The iPhone Air contains Apple's A19 Pro, N1, and C1X chips, making it the most power-efficient iPhone ever made. The A19 Pro chip introduces neural accelerators to each GPU core to increase compute power. The N1, Apple's first wireless chip for the iPhone, has improved Wi-Fi functionality that enables more power-efficient location tracking. The C1X modem is up to twice as fast as the C1 and uses 30% less energy than the Qualcomm modem in the iPhone 16 Pro. Using its own silicon gives Apple more control, allowing it to do things beyond what it could do by buying merchant silicon parts.

LESS IS SAFER: HOW OBSIDIAN REDUCES THE RISK OF SUPPLY CHAIN ATTACKS

Supply chain attacks involve malicious updates sneaking into open-source code. Obsidian minimizes risk by depending on minimal third-party code, often re-implementing functions or forking modules when feasible. When using larger libraries, Obsidian uses version pinning and lockfiles, guaranteeing a deterministic build process.

FORTRA ADDRESSED A MAXIMUM SEVERITY FLAW IN GOANYWHERE MFT SOFTWARE

Fortra has patched a critical deserialization vulnerability (CVE-2025-10035) with a maximum CVSS score of 10.0 in the GoAnywhere Managed File Transfer software that allows attackers to execute arbitrary commands through the License Servlet. The company has urged customers to upgrade to version 7.8.4 or sustaining release 7.6.3 and recommends restricting public access to the GoAnywhere Admin Console to mitigate exploitation risks. This follows previous high-severity vulnerabilities in the same product, including an authentication bypass flaw (CVE-2024-0204) discovered in January 2024.

DEMOCRATS PUSH FOR BIPARTISAN ROLE IN CRYPTO MARKET STRUCTURE BILL

Twelve Senate Democrats, including Kirsten Gillibrand and Cory Booker, called for a bipartisan authorship process on the Clarity Act, arguing they should help draft the crypto market structure bill rather than merely comment on a GOP-led version. Their framework seeks stronger CFTC authority over spot markets, bans on elected officials profiting from crypto projects, and expanded funding for regulators.

TESLA GIVES BIG HINT THAT IT WILL BUILD CYBER SUV, SMALLER CYBERTRUCK

The Cyber SUV and a smaller Cybertruck could potentially be added to Tesla's lineup soon. While the company has not confirmed its plans for the vehicles, a recent promotional video Tesla released seemed to show a mock-up design of the Cyber SUV in plain sight. A smaller Cybertruck design would allow fans in Europe and Asia to purchase the all-electric pickup. There have been regulatory concerns in some countries about the size and sharp edges of the Cybertruck, increasing the need for an 'international' version.

BUILDING NUCLEAR POWER IN THE US IS TOUGH. NASA WANTS TO DO IT ON THE MOON

The US, China, and Russia are racing to build a nuclear reactor on the Moon. The countries have been exploring the idea of jointly deploying nuclear energy on the Moon by the mid-2030s, but NASA leaders are worried that a rival could potentially use its own station to establish a keep-out zone on the lunar surface, limiting US efforts to build up its own presence. NASA now aims to land a reactor on the Moon by late 2029. The agency expects to lean on US industry to design a reactor, get it to the Moon, and operate it.

MAKING REAL GAINS IN WAR ON ALZHEIMER'S

New technologies like AI are helping scientists find new ways to understand and possibly help treat Alzheimer's disease. Scientists are now looking at the possible role of lithium deficiency as a cause in the onset and progression of the disease. The cost for care of patients with the disease is estimated to increase to $1.5 trillion per year by 2050. If scientists are unable to change the course of the disease, then the only real treatment will be physical and palliative care.

INTERCEPTION

Interceptium is a proof of concept that routes web requests through a large language model to generate custom outputs. It passes request data to models that generate HTML that is returned to the browser. These 'interceptors' can craft pages to users' needs and preferences without any input. There are a lot of risks and challenges with this approach, but the goal of the project was only to consider future browser functionalities, as AI's ability to customize and adapt the web is incredibly powerful.
