Scientists achieve electrically driven perovskite laser using dual-cavity design

In a recent Nature study, scientists have demonstrated an electrically driven perovskite laser using a dual-cavity design, addressing a challenge that has persisted in the field for over a decade.

The dual-cavity laser device developed by a team from Zhejiang University shows a lasing threshold an order of magnitude lower than state-of-the-art electrically driven organic lasers and offers superior operational stability with rapid modulation capabilities.

Phys.org spoke with the research team about their work.

New Huntington’s Disease Therapy Slows Patients’ Disease by 75%

Huntington’s disease is a genetic disorder that is caused by an unusual number of repeats in the huntingtin gene; there make the gene too long, and lead to the production of a toxic protein in brain cells. Symptoms of the disease tend to arise when a person is in their 30s or 40s and it is typically fatal within 20 years. New work may change that, however.

Scientists Identify Brain Signal Disruptions Behind Voices in Schizophrenia

A new study reveals a missing area of brain activity in the minds of people with schizophrenia who hear voices.

The analysis of brain wave data suggests a combination of two neurological functions could trigger auditory verbal hallucinations.

Researchers from China found evidence of a breakdown in the ability to prepare the senses for specific words to be spoken. This on its own, however, isn’t enough; another area that filters our brain’s internal chatter is also enhanced in those with schizophrenia who experience unsettling auditory hallucinations.

Sugar fingerprints offer faster, more reliable diagnoses for fungal infections

Hospitals worldwide, including Germany, face a growing problem with fungal infections, with an estimated 6 million cases and 3.8 million deaths each year. According to the World Health Organization (WHO), Candida—a common fungus most people encounter at least once in life—is a top concern. While many know it from mild, superficial infections such as thrush, Candida (especially C. auris and C. albicans) can also reach the bloodstream and cause life-threatening disease.

This is increasingly happening in clinics around the world, where Candida finds an ideal target in weakened patients—after major surgery or chemotherapy, for example. Candida can also cling to medical equipment, like catheters, tubes, or prostheses, forming slimy biofilms that are highly resistant to antifungal drugs.

The European Center for Disease Prevention and Control has recently echoed the WHO in sounding the alarm and calling for better prevention, faster diagnosis, and more effective treatment.

Paper information

🌍 Exciting News! 🌍

Our research team is honored to have two papers accepted at the International Astronautical Congress (IAC) 2025 in Sydney 🇦🇺. Both sessions are scheduled for October 2nd, 2025:

📄 Hybrid GEO–LEO Satellite Network for Multi-Service 5G/6G NTN Connectivity in Australia 🕙 10:15 AM | Room C4.

In a first, scientists observe short-range order in semiconductors

Inside the microchips powering your devices, atoms aren’t just randomly scattered. They follow a hidden order that can change how semiconductors behave.

A team of researchers from the Lawrence Berkeley National Laboratory (Berkeley Lab) and George Washington University has, for the first time, observed these tiny patterns, called short-range order (SRO), directly in semiconductors.

This discovery is a game-changer, as understanding how atoms naturally arrange themselves could let researchers design materials with desirable electronic properties. Such control could revolutionize quantum computing, neuromorphic devices that mimic the brain, and advanced optical detectors.

A Systematic Review of the Use of AI in EFL and EL Classrooms for Gifted Students

There is a growing body of literature that focuses on the applicability of artificial intelligence (AI) in English as a Foreign Language (EFL) and English Language (EL) classrooms; however, educational application of AI in the EFL and EL classroom for gifted students presents a new paradigm. This paper explores the existing research to highlight current practices and future possibilities of AI for teaching EFL and EL to address gifted students’ special needs. In general, the uses of AI are being established for class instruction and intervention; nevertheless, there is still uncertainty about practitioner use of AI with gifted students in EFL and EL classrooms. This review identifies 42 examples of GenAI Models that can be used in gifted EFL and EL classrooms.

Time-released gel packs a one-two punch against aggressive brain tumors

High-grade gliomas are aggressive brain tumors with poor prognosis, largely because even after surgical removal, infiltrative residual tumor cells often regrow during the latency before radiotherapy, leading to recurrence. The standard chemoradiotherapy only modestly improves survival. A crucial window of vulnerability arises post-surgery, before radiotherapy begins, where residual tumor cells are not well addressed by systemic chemotherapy.

Prof. Feng-Huei Lin and Dr. Jason Lin from National Taiwan University have designed a local post-surgical gel packing with sequential delivery of platinum agents that could maintain therapeutic drug concentrations intracranially and synergize with subsequent radiotherapy to eliminate tissue. Their study is published in the Chemical Engineering Journal.

The cutting-edge drug-delivery gel can be directly injected into the surgical cavity following tumor resection. This gel provides sustained local delivery of platinum-based anticancer agents, ensuring effective eradication for residual glioma tissue that remain after surgery. The gel is designed to maximize the therapeutic impact while minimizing systemic exposure.
