🧠 Supportive brain cells might cause cognitive decline

New research suggests that brain cells producing myelin, which is a protective coating on nerve fibers, can become dysfunctional with age. This study focused on participants from the Lothian Birth Cohort 1936, who had cognitive assessments between age 70 and 82. Researchers found that more severe decline was linked to unhealthy myelin and fewer large nerve fibers in post mortem tissue. They discovered reduced NRF2 protein in these cells drives this dysfunction, contributing to cognitive issues during aging. This opens possibilities for repurposing existing drugs to protect cognition later in life. 🧠

⚽ Chelsea offloading strikers Jackson and Delap

Chelsea is reportedly set to raise around £100m through player sales as Nicolas Jackson and Liam Delap approach moves away from the club. These players, deemed surplus to requirements by Xabi Alonso, have been training separately from the first-team squad. Jackson is close to a £60m deal with Aston Villa, while Delap is set to join Nottingham Forest for £45m. Alonso prefers to sell Jackson amid interest from several top clubs, and Delap endured a difficult year at Stamford Bridge. Chelsea will next face Luton Town in the Carabao Cup on Thursday night. ⚽

⚛️ Quantum breakthrough solves Burgers' equation dynamics

Researchers developed a quantum algorithm to solve the dynamics of the nonlinear viscous Burgers’ equation. This work was conducted using Carleman linearization and Permutation Matrix Representation (PMR) techniques. The simulation achieved a six-fold reduction in gate complexity compared to previous block encoding methods. This improved method allows explicit quantum gate construction, bypassing expensive oracle access for efficient fluid simulation. While promising, scaling this approach to genuinely large systems is still unproven due to postselection overhead. 🤯

🔋 Spin coupling boosts quantum battery storage, but work output drops

Researchers found that enhancing dipolar interaction in a two-qubit system significantly boosted maximum ergotropy when used as a quantum battery. This study was conducted at Mohammed V University and Ibnou Zohr University, reporting a 15 percent increase in charging power. The research reveals a complex trade-off between energy storage capacity and the work extractable from a quantum Otto heat engine. While storage capacity rose sharply with greater dipolar coupling, the maximum work obtainable decreased slightly under stronger interactions. This challenges the assumption that improved energy retention automatically leads to better power output in quantum devices.

🕊️ India, China chat peace along LAC border

India and China discussed peace and border delimitation during a meeting between NSA Ajit Doval and Chinese Foreign Minister Wang Yi. The talks took place under the Special Representatives dialogue framework. Doval noted the normalcy resulted from both sides maintaining tranquility along the border areas. Both sides also discussed resuming border trade and strengthening diplomatic ties. This dialogue precedes Xi Jinping's expected visit to India for the BRICS summit. 🤝

🚗 VW's $1.4B tax case to restart in Bombay High Court

The Bombay High Court is re-hearing Volkswagen's $1.4 billion customs tax dispute after failing to deliver a verdict in time. This case involves Skoda Auto Volkswagen India Pvt Ltd and customs authorities regarding imported vehicle parts for the Aurangabad plant. The bench had reserved its judgment on February 26, 2025, but released the matter due to work exigencies. Volkswagen will now have to present its arguments again before a different tax bench. For now, the court has granted VW four weeks of temporary relief. 🚗

🚌 UP gives free bus rides to senior women

The Uttar Pradesh Cabinet approved lifelong free bus travel for women aged 60 and above on UPSRTC buses. This decision, made on Tuesday, August 25, 2026, was part of the Lokmata Ahilyabai Matrushakti Yojana. An estimated 88,438 women passengers could benefit from this facility daily. The move aims to offer financial relief and greater independence to senior women commuters. Special smart cards will be issued by the Transport Corporation for systematic implementation.

🏨 Hotels push for tourism reforms in AP state

The A.P. Star Hotels Association met the new Tourism Special Chief Secretary, Shamsher Singh Rawat, on Tuesday. Led by president R.V. Swamy, the delegation presented a strategic assessment report for 2024–2029. They pushed for faster reforms, including incentives for MSMEs and a permanent industry platform. Key suggestions included better coordination and developing Amaravati as a tourism hub. The association hopes this new leadership will speed up tourism development and job creation. 🏨

🪐 Planet 23x heavier than Earth is still rock?

Researchers confirmed exoplanet GJ 523b defies typical gas-giant rules by maintaining a solid rocky structure. This planet orbits its star and is located in the system, with a mass of 23.5 Earth masses and a radius of 2.55 Earth radii. Measurements were taken using TESS, WIYN, and JWST, with the system being about 170 million years old. Current formation models struggle to explain how such a massive body avoided becoming a gas giant. Future JWST observations are expected to help clarify which of the two competing theories is correct.

🐍 Spectacled cobras in India are genetically the same

Researchers found that spectacled cobras (Naja naja) across India are genetically uniform despite visible differences. This study was conducted by the Evolutionary Venomics Lab (EVL) in Kolkata to aid anti-venom development for the 58,000 annual snakebite deaths. The findings support an African origin for the genus Naja, with dispersal into South Asia during the Miocene era. The research indicates the Indian population is largely panmictic, meaning it's one connected genetic group. This knowledge is crucial for optimizing anti-venom protocols and snakebite biology. 🐍

🔎 9,000-year-old marked arrowheads keep guessing game going

Archaeologists discovered eleven new obsidian arrowheads with intentional, hand-cut markings at Tepecik-Ciftlik, central Turkey. These markings, including crosses and chevrons, were found on arrowheads dating back nearly nine thousand years. The study detailed these findings on 12 pieces, bringing the regional count to 54, published in PLOS One. The purpose of these unique designs remains a puzzle, suggesting ritual or decoration rather than simple hunting signs. Future research needs to decipher why this practice was so localized to specific Neolithic communities. 🧐
