A study of platinum-coated nanoparticles shows how energy balance controls crystal growth Glass beads (Courtesy: Shutterstock/Schmidt) Many catalysts are made using core-shell nanoparticles, in which the core is a structurally important or inexpensive material and the thin shell surrounding it is an expensive metal such as platinum. Since catalytic reactions occur on the surface, this helps to reduce the amount of platinum required and therefore lowers costs. Crystal structures are described based on the smallest repeating unit of the crystal (the unit cell) using the Bravais lattice system. Three important crystal structures are face-centred cubic (fcc, atoms at the corners…

Cook explained that to handle users who might want to use Siri AI extensively, the company plans an upgrade option through iCloud+, though it is too early to define the specifics. (Incoming CEO John Ternus said Apple is focused on its own approach to artificial intelligence, but continues to see “enormous opportunity” in the sector.) What the analysts said Discussing the results, Morgan Stanley analyst Erik Woodring pointed to decelerating services growth and memory costs nibbling at the edge of Apple’s margins. “Apple’s leverage over the supply chain appears to be in question,” he said, adding it’s not clear whether…

Welcome back to another edition of M&A Monthly, where TeleGeography’s GlobalComms team tracks the deals that keep the world connected. Here’s everything you need to know about mergers and acquisitions across the global telecom landscape.

Lidar technology uses pulses of infrared light to calculate distances and create detailed 3D maps of the surrounding environment. This allows autonomous vehicles to detect objects in their path and respond quickly. However, conventional lidar sensors are often large and costly, and many rely on moving components that can wear out over time. These limitations make the systems difficult to use in a wider range of settings. MIT researchers have now developed an approach that could lead to smaller, more durable lidar sensors that operate without any moving parts. Their advance centers on a new silicon-photonics chip, a type of…

AWS recorded its fastest growth in more than four years during the second quarter, but Amazon said it still lacked enough computing capacity to meet customer demand despite raising its 2026 capital spending forecast to $220 billion.AWS revenue rose 37% year over year to $42.2 billion in the quarter ended June 30. The result exceeded the 31.21% growth expected by analysts surveyed by LSEG and marked the cloud unit’s strongest performance in 18 quarters.“AWS is booming right now,” Amazon CEO Andy Jassy said during the company’s earnings call. AWS added more than $4.6 billion in revenue from the previous quarter,…

The screenshot may look convincing, but it doesn’t necessarily prove that the payment, booking or conversation is genuine 30 Jul 2026  •  , 6 min. read Someone sends you a screenshot showing that a payment has gone through. It carries the right logo, amount, timestamp and transaction status. Yet the money never arrives. What passes for proof today can generally be very different from just a few years ago. Screenshots, often commonly treated as a convenient record of a payment, message or online conversation, are hard to take at face value. To be sure, they have always been open to…

An intervertebral disc disease diagnosis changes more than a dog’s exercise routine. It can alter how mornings begin, where the dog sleeps, how bathroom trips are managed, and how closely every movement is watched. The first days at home can feel particularly demanding. Owners may be balancing medication schedules, restricted activity, veterinary appointments, interrupted sleep, and concern about whether recovery is progressing normally. For dogs with severe weakness or paralysis, daily care may also include lifting, bladder assistance, frequent bedding changes, and skin checks. Not every dog needs the same level of support. Some recover well after a period of…

As businesses lean on AI for productivity gains and better customer experiences, security teams are struggling to secure this adoption. This challenge is further compounded by frontier AI models like Mythos. Not only are these models accelerating vulnerability discovery—leaving IT teams scrambling to secure aging hardware—they are also empowering enterprising IT engineers to spin up AI-powered agents to speed up operations. “Yesterday’s insecure Python scripts have evolved into today’s insecure, autonomous IT agents.” If we peel back the layers, while AI is a significant trend, security teams have weathered the internet era, the BYOD and mobility landscape, the age of…
