How Huawei’s new chip changes the US-China tech landscape

Posted by in categories: computing, economics, mobile phones

The recent unveiling of Huawei Technologies’ Mate 60 Pro smartphone has sparked a whirlwind of chatter across political, economic, and technological spectrums. The device, a showcase for China’s growing prowess in semiconductor technology, has left industry insiders debating whether it signifies a significant milestone in the US-China technology cold war.

Ever since Huawei was blacklisted by the US in 2020, denying it access to state-of-the-art American chip technologies, the tech giant has been cloaked in secrecy. In this mysterious atmosphere, the launch of Mate 60 Pro has become the subject of intense scrutiny, primarily due to the chip powering it—dubbed Kirin 9000s.

Scientists reveal the hidden math that governs how neurons cluster in the brain

Posted by in categories: computing, mathematics, neuroscience

The density of neurons in the brain is governed by a fundamental mathematical function, new research finds.

The discovery, which holds true across a variety of mammals, could help researchers make better computer models of the brain in the future.

Light-field control of real and virtual charge carriers

Posted by in categories: computing, materials

Year 2022 femtosecond logic gates for computers once thought to be almost a myth only for 2099 dreams is now real.


Light-field control of real and virtual charge carriers in a gold–graphene–gold heterostructure is demonstrated, and used to create a logic gate for application in lightwave electronics.

What A General Diagonal Argument Looks Like (Category Theory)

Posted by in categories: computing, mathematics

Diagonal Arguments are a powerful tool in maths, and appear in several different fundamental results, like Cantor’s original Diagonal argument proof (there exist uncountable sets, or “some infinities are bigger than other infinities”), Turing’s Halting Problem, Gödel’s incompleteness theorems, Russell’s Paradox, the Liar Paradox, and even the Y Combinator.

In this video, I try and motivate what a general diagonal argument looks like, from first principles. It should be accessible to anyone who’s comfortable with functions and sets.

PeLEDs offer to make encryption cheaper and more sustainable

Posted by in categories: computing, encryption, quantum physics, sustainability

Perovskite light-emitting diode is used as the light source for a quantum random number generator used in encryption.

Encryption plays an important role in protecting information in this digital era, and a random number generator plays a vital part in this by providing keys that are used to both encrypt and unlock the information at the receiving end.

Now, a team of researchers has made use of light-emitting diodes made from the crystal-like material perovskite to devise a new type of Quantum Random Number Generator (QRNG) that can be used for encryption but also for betting and computer simulations.

Apple bows to EU, iPhone 15 likely to have USB-C port

Posted by in categories: climatology, computing, law, mobile phones

EU law requires manufacturers to adopt Type-C chargers in phones, tablets, etc by December 2024.

Apple will switch out its proprietary Lightning charging port in iPhones to be compatible with a USB Type-C cable instead, reported.

The EU law says that by 2024-end, all mobile phones, tablets, and cameras sold in countries under the EU will have to be equipped with a USB-C charging port. From spring 2026, the obligation will extend to laptops as well. The law’s overall purpose is to cut down on environmental waste and save consumers an estimated $247 million per annum.

The limestone spheroids of ‘Ubeidiya: Intentional imposition of symmetric geometry by early hominins?

Posted by in category: computing

Limestone spheroids, enigmatic lithic artifacts from the ancient past, have perplexed archaeologists for years. While they span from the Oldowan to the Middle Paleolithic, the purpose behind their creation remains a subject of intense debate.

Now, a study conducted by a team from the Computational Archaeology Laboratory of the Hebrew University of Jerusalem, in collaboration with researchers from Tel Hai College and Rovira i Virgili University seeks to shed light on these mysterious objects, offering insights into the intentions and skills of early hominins.

Spheroids are among the most enduring yet least understood , often considered as by-products of percussive tasks. However, the team’s research challenges this conventional wisdom. The central question at the heart of this study is whether these spheroids were unintentional by-products or intentionally crafted tools designed for specific purposes.

Scientists Slowed Down a Chemical Reaction 100 Billion Times to See What Happens

Posted by in categories: chemistry, computing, particle physics, quantum physics

Scientists have been able to observe a common interaction in quantum chemistry for the first time, by using a quantum computer to shadow the process at a speed 100 billion times slower than normal.

Known as a conical intersection, the interactions have long been known about, but are usually over in mere femtoseconds – quadrillionths of a second – making direct observations impossible to carry out.
