In future, doctors hope the technology could revolutionise the treatment of conditions such as depression, addiction, OCD and epilepsy by rebalancing disrupted patterns of brain activity.
Jacques Carolan, Aria’s programme director, said: “Neurotechnologies can help a much broader range of people than we thought. Helping with treatment resistant depression, epilepsy, addiction, eating disorders, that is the huge opportunity here. We are at a turning point in both the conditions we hope we can treat and the new types of technologies emerging to do that.”
The trial follows rapid advances in brain-computer-interface (BCI) technology, with Elon Musk’s company Neuralink launching a clinical trial in paralysis patients last year and another study restoring communication to stroke patients by translating their thoughts directly into speech.
When used correctly, font selection usually goes unnoticed, blending seamlessly with content and reader. When the One Times Square Billboard used a retired Microsoft Word default Calibri font to usher in 2025’s “Happy New Year” message, it was immediately met with sarcastic scorn and delightful derision for the uninspired choice (at least by people who pay attention to such things). Had the font faux pas been the branding rollout of a new app, product, or company, the consequences might have been more severe.
Hanyang University researchers in Korea have attempted to take the intuition and subjective judgment out of the art of font selection. Using computational tools and network analysis to develop an objective framework for font selection and pairing in design, the researchers aim to establish foundational principles for applying typography in visual communication.
Font choice plays a critical role in visual communication, shaping readability, emotional resonance, and overall design balance across mediums. According to the researchers, designers have traditionally relied on subjective rules for font pairing, such as mixing Serif and Sans-Serif or creating contrast. These rules are difficult to formalize and often apply to only a narrow subset of fonts.
MIT researchers are developing techniques to make quantum gates, the basic operations of a quantum computer, as fast as possible in order to reduce the impact of decoherence. However, as gates get faster, another type of error, arising from counter-rotating dynamics, can be introduced because of the way qubits are controlled using electromagnetic waves.
Single-qubit gates are usually implemented with a resonant pulse, which induces Rabi oscillations between the qubit states. When the pulses are too fast, however, “Rabi gates” are not so consistent, due to unwanted errors from counter-rotating effects. The faster the gate, the more the counter-rotating error is manifest. For low-frequency qubits such as fluxonium, counter-rotating errors limit the fidelity of fast gates.
“Getting rid of these errors was a fun challenge for us,” says Rower. “Initially, Leon had the idea to utilize circularly polarized microwave drives, analogous to circularly polarized light, but realized by controlling the relative phase of charge and flux drives of a superconducting qubit. Such a circularly polarized drive would ideally be immune to counter-rotating errors.”

Job displacement is a serious issue everywhere, but professional computer science majors should get ready for a tightening of the belt in their field.
A Semafor article published this month, written by Reed Albergotti, shows how Amjad Masad, CEO of Replit, is enthusiastic about cutting the firm’s workforce in half, while boosting revenue something like 500% on the back of agenticAI.
Replit’s new tool can reportedly “write a working software application with nothing but a natural language prompt” and that’s going to usher in a new renaissance in computing, while costing some careerists their jobs.
How Symmetry Shapes the Universe: A Peek into Persistent Symmetry Breaking.
Imagine a world where certain symmetries—like the balance between left and right or up and down—are spontaneously disrupted, but this disruption persists regardless of temperature. Scientists are exploring this fascinating behavior in a special type of mathematical framework known as biconical vector models. These models examine how symmetries behave under specific conditions, especially in a universe with two spatial dimensions and one time dimension (2+1 dimensions).
This study takes a closer look at these models and reveals exciting new insights about symmetry breaking in a way that respects established physical principles. Here’s what the researchers discovered:
1. Symmetry Breaking Basics: The study confirms that symmetry can break persistently when these models are designed to include both continuous and discrete symmetry features (described by the mathematical groups O(N)×Z₂). This breaking shifts from one type of symmetry (O(N)×Z₂) to another (O(N)) as temperature rises, but only under certain conditions.
2. Precision at Zero Temperature: By using advanced computational methods, the team accurately described how these models behave when the temperature is absolute zero. Their findings are valid for a wide range of systems, provided the number of components, N, is 2 or greater.
3. Finite-Temperature Effects: As the temperature increases, the discrete symmetry (Z₂) remains the only one to break, ensuring that the laws of physics, specifically the Hohenberg-Mermin-Wagner theorem, are respected. This theorem essentially states that continuous symmetries cannot break spontaneously in 2D systems at finite temperatures.
4. A Critical Threshold: The researchers calculated that this unusual symmetry-breaking phenomenon can only be observed when N (the number of components in the system) exceeds a critical value, approximately 15.
