Google Search Is Going Global
Google’s cleaning house: no more country-specific domains like google.co.uk or google.de. Instead, everyone gets routed to google.com—no matter where you are. It’s like turning all the local coffee shops into one giant global café. This shift means more consistent results worldwide, but it could also blur the local flavor we’re used to. The change is rolling out now, so next time you search, you might just be sipping from the same digital cup as someone across the globe.

Ancient crocodiles’ secret to surviving 2 mass extinctions stuns scientists
The ancestors of modern crocodiles survived two mass extinctions throughout their 230-million-year history.
ften labeled as living fossils, crocodilians have inhabited swamps and rivers for millions of years.
Surprisingly, the ancestors of modern crocodiles survived two mass extinctions throughout their 230-million-year history.
Researchers at the University of Central Oklahoma (UCO) and the University of Utah have discovered a key to the long-term evolutionary success of these prehistoric creatures: their exceptional adaptability in both diet and habitat.
“Lots of groups closely related to crocodylians were more diverse, more abundant, and exhibited different ecologies, yet they all disappeared except these few generalist crocodylians alive today,” said Keegan Melstrom, lead author and assistant professor at UCO.
For scientists and conservationists, knowing how species survive planetary crises can lead to more effective protection of vulnerable species.
“Aquatic hypercarnivores, terrestrial generalists, terrestrial hypercarnivores, terrestrial herbivores—crocodylomorphs evolved a massive number of ecological roles throughout the time of the dinosaurs,” added Melstrom.
However, during the Late Cretaceous, this incredible diversity began to wane.
At the time of the end-Cretaceous mass extinction, the survivors were largely the semiaquatic generalists and some aquatic carnivores – the ancestors of the crocodilians we see today.
This research involved a large-scale effort, with the authors examining skulls from 99 extinct crocodylomorph species and 20 living crocodylian species across numerous museum collections worldwide.
The team says that dietary flexibility might be crucial for the survival of critically endangered species like the Gharial and Cuban Crocodile amidst the current potential sixth mass extinction.
A trick before the split
With the aim of finding the elusive oxygen evolution reaction (OER), Geiger’s team used an iron-rich mineral known as hematite as an electrode. Geiger’s lab fabricated a water-PR-SHG technique that let them observe the water molecules’ dynamics over the electrode’s surface.
There is a cost to achieving the oxygen flips. The energy expenditure required for the rearrangement of water molecules was calculated, and it turned out to be almost equal to the energy-binding water as a liquid.
“These electrodes are negatively charged, so the water molecule wants to put its positively charged hydrogen atoms toward the electrode’s surface,” Geiger said. “In that position, electron transfer — from water’s oxygen atoms to the electrode’s active site — is blocked.”
Toward better catalysts—and a hydrogen economy
The results do much more than explain water splitting’s inefficiency; they also offer a guide on how to change it for the better.
“A key goal is to move away from fossil fuels and toward a hydrogen economy,” Geiger said. “One long-pursued idea is to use a material with the right electrocatalytic and optical properties. Through solar radiation, it generates catalytically active sites that do the electrochemistry.”
“You still need to apply a current to perform the electrochemistry, but the sun’s photons allow you to apply less voltage. And the less voltage you apply, the cheaper the fuel becomes.” Our study shows that the catalyst surfaces need to be tailored to facilitate water flipping so the electron transfer can initiate.”
At its 2024 launch, the firm stated that the Turing chip can process AI models with 30 billion parameters and complete over 2,700 functional verifications within 40 days—three times faster than the industry standard. This level of performance enables Iron to think, adapt, and respond to a variety of tasks with flexibility and human-like decision-making.
The robot’s “Eagle Eye” visual system, powered by advanced cameras, ensures precise environmental awareness and decision-making capabilities. “It also features a 720° AI vision system that can also be found in XPENG’s autonomous driving technology,” said the firm in a statement.

US chemists find hidden energy barrier in water splitting for hydrogen fuel production
The results do much more than explain water splitting’s inefficiency; they also offer a guide on how to change it for the better.
Water splitting has long been hailed as a promising path to clean hydrogen fuel. But while the process looks elegant on paper, it turns out to be far less efficient in practice, demanding significantly more energy than theory predicts. Now, scientists at Northwestern University have discovered a surprising culprit behind this energy gap.
“When you split water, two half-reactions occur,” said Northwestern’s Franz Geiger, who led the study. The half-reaction that produces oxygen is really difficult to perform because everything has to be aligned just right. It ends up taking more energy than theoretically calculated. If you do the math, it should require 1.23 volts. But, in reality, it requires more like 1.5 or 1.6 volts.”
“Providing that extra voltage costs money, and that’s why water splitting hasn’t been implemented at a large scale. By designing new catalysts that make water flipping easier, we could make water splitting more practical and cost-effective.”
The study reveals this molecular acrobatics as a key barrier to oxygen evolution, a critical half-reaction in water splitting. Even more importantly, the researchers found that adjusting the pH of water can make the flipping easier — opening new avenues to optimize the reaction and lower the cost of clean hydrogen fuel.
Iron: China’s humanoid robot gets supercomputer-like brainpower, eagle-eye vision
XPENG sees Iron as a personal assistant for admin and customer service in homes, offices, and retail—beyond just manufacturing.
Chinese carmaker Guangzhou Xiaopeng Automotive Technology, or XPENG, has unveiled its updated humanoid robot, Iron.
The humanoid robot is powered by the Turing AI chip, with 60 joints, 200 degrees of freedom, and 3,000 TOPS of processing power.
The unveiling is part of XPENG’s AI Tech Tree strategy, which combines AI, energy solutions, and embodied intelligence to build a future ecosystem of smart EVs, humanoid robots, and flying vehicles.
In November, the electric vehicle (EV) manufacturer went the Tesla way by unveiling Iron, its first humanoid robot. XPENG reported that Iron is already active on its automotive production lines, helping assemble its upcoming EVs.
Robotics meets autonomy
The firm claims that its humanoid robot showcases cutting-edge advancements in robotics, blending design, mobility, AI, and automotive technology.
The robot stands 5’8″ tall and weighs 154 pounds (70 kilograms) it is designed with a human-like structure; Iron features 1:1 proportional hands and 22 degrees of freedom, allowing for precise and flexible object manipulation.
According to XPENG, its advanced mobility is driven by end-to-end large models and reinforcement learning, enabling smooth, natural movements and stable walking without the jerky motions typical of traditional robots.
