MRI reveals long-term organ abnormalities after COVID-19

Posted by in categories: biotech/medical, neuroscience

COVID-19 can affect various organs in the body, such as the brain, lungs, heart, and kidneys. But what happens to these organs after the infection is over? How long does it take for them to heal? A new study has tried to answer these questions by using MRI scans to look at multiple organs of people hospitalized with COVID-19.

The study, published in The Lancet Respiratory Medicine, is one of the most comprehensive post–COVID–19 MRI studies to date. It involved 259 patients who had been hospitalized with COVID-19 in the U.K. and 50 people who had never been… More.

Solar cars can reduce global charging needs by half

Posted by in categories: solar power, sustainability, transportation

A new study modeled the behavior of solar vehicles in 100 locations around the world.

According to a new study, solar energy can provide a range of between 6 and 18 miles (11 and 29 kilometers) for electric vehicles each day, cutting down on the requirement for charging by half. The study took into account the capabilities of solar-powered vehicles in urban settings in 100 locations across the world, modeling the behavior of the cars in busy cities.

Honda releases its first-ever series production V8 engine

Posted by in category: transportation

The BF350 VTEC motor makes an ideal choice for large pontoon boats to offshore vessels.

Honda’s Variable Valve Timing and Lift Electronic Control (VTEC) engines are known for their performance, refinement, and durability. However, their production engine series lacked a V8 option in its lineup, except for a few versions developed for racing.

How a student invented an affordable fire-fighting robot

Posted by in categories: employment, robotics/AI

FireBot is a high-temperature resistant and wirelessly controlled robot that can assist firefighters in search and rescue operations.

Firefighters have one of the most dangerous and heroic jobs in the world. They risk their lives every day to save people from burning buildings, often without knowing what they will face inside. But what if there was a way to make their job safer and easier?

Saudi Arabia to resume building the world’s tallest tower

Posted by in categories: business, economics, space

Standing 3,280 feet (1,000 meters) tall, the Jeddah Tower will dwarf the Burj Khalifa by over 560 feet (172 m).

Jeddah Economic Company (JEC), the firm behind the ambitious Jeddah Tower Project in Saudi Arabia, has announced the resumption of work on the world’s tallest building, media reports have confirmed. The project that began in 2010 came to an abrupt halt in 2017.

Countries in the Middle East have been pouring money into ambitious projects to attract tourism and businesses and reduce their dependence on oil exports for income. The city of Dubai is replete with examples of structures meant to attract people from all over the world, whether one looks at the Palm Islands or the Moon-themed resort.

The Problem with Elon Musk

Posted by in categories: Elon Musk, robotics/AI

The new biography of Elon Musk by Walter Isaacson just came out on September 12. How has Musk already accomplished so much? Why does his success bother so many people? And what the heck is his fascination with the letter X?

Love him or hate him, Elon Musk seems to be everywhere with a hand in everything. He’s the richest person in the world, with an estimated net worth of between $226 Billion and $249 Billion depending on who does the estimating. And between Twitter, now X, SpaceX, Tesla, The Boring Company, OpenAI, X.Ai., and PayPal, he’s probably been involved in something that currently touches your life or will in the near future, especially if he gets his way.

Step forward for massive DNA computer systems

Posted by in categories: biotech/medical, computing, information science

The group at Shanghai Jiao Tong University has demonstrated a DNA computer system using DNA integrated circuits (DICs) that can solve quadratic equations with 30 logic gates.

Published in Nature, the system integrates multiple layers of DNA-based programmable gate arrays (DPGAs). This uses generic single-stranded oligonucleotides as a uniform transmission signal can reliably integrate large-scale DICs with minimal leakage and high fidelity for general-purpose computing.

To control the intrinsically random collision of molecules, the team designed DNA origami registers to provide the directionality for asynchronous execution of cascaded DPGAs. This was used to assemble a DIC that can solve quadratic equations with three layers of cascade DPGAs comprising 30 logic gates with around 500 DNA strands.
