Changing reality with virtual technologies

Posted by in categories: augmented reality, robotics/AI, virtual reality

From attending a meeting to enjoying a live performance or, perhaps, taking a class at the University of Tokyo’s Metaverse School of Engineering, the application of virtual reality is expanding in our daily lives. Earlier this year, virtual reality technologies garnered attention as tech giants, including Meta and Apple, unveiled new VR/AR (virtual reality/augmented reality) headsets. We spoke with VR and AR specialist Takuji Narumi, an associate professor at the Graduate School of Information Science and Technology, to learn about his latest research and what VR’s future has to offer.

At the Avatar Robot Café DAWN ver. β, employees serve customers via a digital screen and engage in conversation using avatars of their choice, such as an alpaca and a man with blue hair.

Billions of Email and Password Combinations Leaked by DarkBeam

Posted by in category: cybercrime/malcode

This post is also available in: he עברית (Hebrew)

DarkBeam is a digital risk protection firm, which left its interface unprotected and so exposed records with user emails and passwords from previously reported and non-reported data breaches. These leaked logins present cybercriminals with almost limitless attack capabilities.

The CEO of SecurityDiscovery Bob Diachenko first identified the leak, and he states that it contained over 3.8 billion records. DarkBeam has apparently been collecting information to alert its customers in case of a data breach, but this incident will most likely affect more than only DarkBeam users.

Ultrafast dense DNA functionalization of quantum dots and rods for scalable 2D array fabrication with nanoscale precision

Posted by in categories: biotech/medical, nanotechnology, quantum physics

Abstract: Full Publication #OpenAccess.

Scalable fabrication of two-dimensional (2D) arrays of quantum dots (QDs) and quantum rods (QRs) with nanoscale precision is required for numerous device applications. However, self-assembly–based fabrication of such arrays using DNA origami typically suffers from low yield due to inefficient QD and QR DNA functionalization. In addition, it is challenging to organize solution-assembled DNA origami arrays on 2D device substrates while maintaining their structural fidelity. Here, we reduced manufacturing time from a few days to a few minutes by preparing high-density and rehydration process. We used a surface-assisted large-scale assembly (SALSA) method to construct 2D origami lattices directly on solid substrates to template QD and QR 2D arrays with orientational control, with overall loading yields exceeding 90%. Our fabrication approach enables the scalable, high fidelity manufacturing of 2D addressable QDs and QRs with nanoscale orientational and spacing control for functional 2D photonic devices.


Dehydration and surface-assisted assembly enable rapid, scalable quantum dot and quantum rod 2D arrays with nanoscale precision.

ChatGPT’s New Upgrade Teases AI’s Multimodal Future

Posted by in categories: futurism, robotics/AI

ChatGPT isn’t just a chatbot anymore.

OpenAI’s latest upgrade grants ChatGPT powerful new abilities that go beyond text. It can tell bedtime stories in its own AI voice, identify objects in photos, and respond to audio recordings. These capabilities represent the next big thing in AI: multimodal models.

“Multimodal is the next generation of these large models, where it can process not just text, but also images, audio, video, and even other modalities,” says Dr. Linxi “Jim” Fan, Senior AI Research Scientist at Nvidia.

Marin transportation agency backs faster electric-vehicle transition

Posted by in categories: climatology, law, sustainability

The Transportation Authority of Marin board has voted to accept a framework to accelerate the transition to electric vehicles, in some cases faster than required under state law.

The “Marin Countywide Electric Vehicle Acceleration Strategy,” developed by the interagency Marin County Climate and Energy Partnership, is meant to provide a playbook of policies and actions for jurisdictions to employ to ready their communities for a growing number of electric vehicles.

Several Marin communities have already accepted the strategy, and the Transportation Authority of Marin board did so on Thursday. The authority is a state-managed congestion management agency that also provides rebates to public agencies for installing charging stations and electrifying their vehicle fleets.

Laser-Powered Leap: MXene and the Future of Rechargeable Battery Technology

Posted by in categories: energy, sustainability

Researchers used laser pulses to enhance MXene’s electrode properties, leading to a potential breakthrough in rechargeable battery technology that could surpass traditional lithium-ion batteries.

As the global community shifts towards renewable energy sources like solar and wind, the demand for high-performance rechargeable batteries is intensifying. These batteries are essential for storing energy from intermittent renewable sources. While today’s lithium-ion batteries are effective, there’s room for improvement. Developing new electrode materials is one way to improve their performance.

Genflow makes progress towards clinical trial of NASH gene therapy

Posted by in categories: biotech/medical, life extension

Gene therapy company Genflow Biosciences has received positive feedback from Belgium’s Federal Agency for Medicines and Health Products as it seeks to move into human clinical trials. Genflow is developing gene therapies that target the aging process, with a focus on reducing and delaying age-related diseases.

Genflow’s approach involves the use of adeno-associated virus (AAV) vectors to deliver copies of the Sirtuin-6 (SIRT6) gene variant found in centenarians into cells. Sirtuins are a group of proteins that play a vital role in regulating various cellular processes. In recent years, SIRT6 has gained attention for its potential role in promoting healthy aging.

Genflow says it has received written advice from the FAHMP to commence clinical trials of its lead compound (GF-1002) in patients suffering from NASH, an aggressive form of non-alcoholic fatty liver disease, rather than in healthy volunteers. While further discussions and agreement with the European Medicine Agency (EMA) are still required, Genflow says that it expects a NASH clinical trial to commence in approximately 18 months.
