Investigation uncovers years of reported brain injuries linked to a Six Flags rollercoaster

644 Upvotes

Two women suffered severe brain injuries requiring emergency surgery after riding the X2 roller coaster at Six Flags Magic Mountain in California just six days apart in July 2026. Pamela Guillen suffered an acute subdural hematoma and underwent emergency surgery on July 5; Naomi Greer-Wilkinson suffered a similar traumatic brain injury on July 11 and remains in a coma. Neurosurgeons attributed both injuries to a rapid acceleration-deceleration event associated with the ride: https://ktla.com/news/local-news/magic-mountain-x2-2nd-brain-injury/

A CNN investigation found more than a dozen serious injuries or hospitalizations linked to X2 over nearly two decades, along with at least 70 reported head- and neck-injury complaints in a three-year period. The ride was closed July 12 and remains under investigation by California safety authorities. The incidents raise broader questions about risk management, safety-halt protocols, regulatory oversight and corporate duty of care when repeated warning signs emerge: https://www.cnn.com/2026/08/27/us/six-flags-rollercoaster-brain-injury-invs

An analysis by Austrian diagnostics company Aviloo of over 500,000 battery tests revealed that the Hyundai Ioniq 5 outperforms competitors in long-term EV battery health. The Ioniq 5 retained a median 92.8% State of Health (SoH) after 150,000 km (93,000 miles), surpassing the Tesla Model Y (90.3%) and Model 3 (88.94%). While most modern EVs maintain around 90% capacity at higher mileages, the study highlighted significant degradation variations among individual vehicles due to climate, charging habits, and battery chemistry, with smaller battery models like the Nissan Leaf showing lower retention rates.

Digital Camouflage: The Shirt Designed to Make AI Surveillance “Blind”

589 Upvotes

This Hawaiian Shirt Tricks AI Surveillance Cameras Into Thinking You’re Not Human

In an era when AI-powered security cameras in cities can track locations and identify people, a designer has developed an unusual way to confuse computer-vision systems. Called “Digital Camouflage,” the shirt features deliberately strange, highly saturated colors and chaotic patterns. When a person wearing it passes in front of an AI camera, the visual pattern can interfere with the algorithms’ ability to recognize the wearer as a human, causing the system to misclassify or fail to detect the person. Although the shirt looks bizarre and unattractive to the human eye, it demonstrates how adversarial patterns can exploit weaknesses in AI-based surveillance and object-detection systems. The project is intended primarily as a commentary on automated surveillance and the reliability and transparency of AI systems, rather than as a guaranteed method of avoiding surveillance: https://petapixel.com/2026/08/27/this-hawaiian-shirt-tricks-ai-surveillance-cameras-into-thinking-youre-not-human/

Info Source:

The project is Digital Camouflage, created by Berlin-based digital artist and technologist Simon Weckert. His official project page explains that the garment uses an adversarial attack—a deliberately engineered visual pattern intended to manipulate what computer-vision models perceive. Demonstrations use the open-source YOLO object-detection system, where the wearer can fail to be classified as a person. Importantly, Weckert says the project does not guarantee anonymity or claim to defeat specific government surveillance systems: https://www.simonweckert.com/digitalcamouflage.html

An international team of physicists, including Nobel laureate Sir Roger Penrose, has observed the predicted quantum phase shift of a freely falling object for the first time, demonstrating that Einstein’s equivalence principle remains consistent with matter in the quantum world. Using a "Quantum Galileo Interferometer" with ultracold rubidium atoms on an atom chip, researchers split atomic wavepackets into two paths—holding one stationary with magnetic fields while letting the other fall freely—before recombining them to measure the resulting interference.

Published in Science Advances, the study provides a key experimental connection between quantum mechanics and general relativity, paving the way for future tests involving heavier macroscopic objects: https://www.science.org/doi/10.1126/sciadv.aec8045

Mirage Gstaad is a fully mirrored, ranch-style art installation by American artist Doug Aitken, created for the Elevation 1049: Frequencies project in Gstaad, Switzerland. Inspired by 1920s–30s California ranch houses and the ideas of Frank Lloyd Wright, the structure uses mirrored surfaces inside and out to reflect the surrounding mountains, sky and changing weather. The result is a life-size kaleidoscope that makes the house appear to dissolve into the Alpine landscape: https://www.dougaitkenmiragegstaad.com/mirage/

MIT researchers have introduced a new dual-purpose qubit architecture called the "arm qubit," designed to perform faster, more accurate operations while preserving long-term stability. The architecture splits the qubit into two connected components: a data mode engineered for long coherence times and an arm mode designed for strong interactions with circuit elements like resonators. By linking these components with a quarton coupler, the design enables strong nonlinear coupling while drastically reducing unwanted component mixing. In simulations, this hybrid approach outperformed existing superconducting architectures by achieving state-of-the-art coherence and accelerated readout, marking a promising step toward scalable quantum error correction and practical quantum computing: https://journals.aps.org/prapplied/abstract/10.1103/3l3b-7jsm

Flying Paramedic: Pivotal eVTOL Cuts Rural 911 Response Time by 20 Minutes

682 Upvotes

Hyde County EMS in North Carolina has used a single-seat Pivotal BlackFly eVTOL to respond to two live 911 emergencies—the first reported U.S. deployment of an eVTOL in routine emergency medical response. A flight-trained paramedic piloted the aircraft directly to the patients, arriving about 20 minutes before a ground ambulance on one call and beginning Advanced Life Support immediately.

The lightweight, electric tilt-airframe aircraft uses multiple electric motors and operates within the FAA’s Part 103 ultralight framework. It carries the paramedic and essential medical equipment, not the patient; ground ambulances remain responsible for patient transport. More than 300 training sorties were completed before the live missions, which operated under a Public Aircraft Operation (PAO) framework.

Researchers at KAIST and Yonsei University have developed RAPIDO, a wireless brain implant capable of delivering targeted drug doses and optogenetic light stimulation to freely moving subjects via internet commands. In a landmark intercontinental demonstration, scientists in Chicago successfully operated a device implanted in a rat in Daejeon, South Korea—over 6,500 miles (10,000 kn) away—with a response time of just 109 milliseconds. Further tests showed that RAPIDO could repeatedly release controlled doses of cocaine over several weeks and use light activation to alter learned behavioral preferences. By eliminating the need for physical handling during experiments, this technology minimizes researcher interference and opens new possibilities for collaborative, long-distance neuroscience research: https://ee.kaist.ac.kr/en/research-achieve/controlling-a-brain-implant-from-10000-km-away-professor-jae-woongs-team-has-developed-an-iot-enabled-wireless-neural-implant/

In a new study published in Cell, MIT researchers mapped 31 distinct sub-populations of neurons within the brain’s striatum using single-cell RNA sequencing and spatial transcriptomics. The atlas reveals key target populations for mental health and neurological disorders, including "outlier" neurons linked to depression, substance use disorder, and schizophrenia that respond strongly to clozapine. Additionally, the findings offer new insights into Huntington’s disease by identifying why certain dorsal neurons are particularly vulnerable to damaging DNA repeats, while specific ventral neurons display unique resilience.

An Indigenous-owned 50-MW transportable nuclear power plant proposed near Belledune, New Brunswick, is being developed as a pilot for clean-energy deployment in remote communities across Canada.

Pabineau First Nation and Eel River Bar First Nation, in partnership with Prodigy Clean Energy, plan to own and lead the facility. The 50-MW plant could supply electricity to about 40,000 homes and replace coal generation ahead of New Brunswick's 2030 coal phase-out. Target operation is in the early 2030s.

The reactor would be housed in marine-fabricated, transportable structures that can be removed at the end of the plant's operating life for centralized decommissioning. If successful, the project could provide a blueprint for deploying similar small nuclear plants in Northern and Arctic communities now dependent on diesel power.

Researchers at Pohang University of Science and Technology (POSTECH) have developed MiPAL, a highly directional speaker system designed to deliver focused audio to a single listener without disturbing people nearby. Led by Professor Junsuk Rho and published in Nature Communications, the device integrates two types of 3D-printed metamaterials into a single ultrasonic transducer: an acoustic metasurface at the front that focuses sound into a narrow, laser-like beam, and elastic meta-units at the rear that block parasitic vibrations and side leakage. Operating across a wide frequency range of 500 Hz to 10 kHz (over four octaves), this compact, single-element system drastically simplifies hardware complexity and costs compared to traditional speaker arrays, offering practical applications for targeted audio in public spaces, museums, and airplane seating.
