China or US — who is really winning the supercomputer race?

Posted by in category: supercomputing

According to supercomputer guru, even despite sanctions, China has more supercomputers than the US.

A supercomputer is faster, more expensive, and much bigger than your humble personal computer. They are used by scientists and researchers in tech companies and labs to test theories and models with intensive databases.

Keeping a tab on which is the fastest supercomputer in the world is the Top500 List, which comes out twice every year – in November and June. It is the most coveted and sought-after ranking of the top supercomputers in the world. However, over the years, the rankings have been affected due to sociopolitical factors.

Airless bike tires made with NASA technology are now on sale

Posted by in category: transportation

The METL tire is made from a shape memory alloy, making it elastic like rubber yet strong like titanium.

The much-hyped airless tire technology developed by NASA for its rovers, later commercialized for terrestrial use by The SMART Tire Company (STC), is now available for sale.

Student-built nuclear fusion reactor to debut in Australia

Posted by in categories: nuclear energy, particle physics

The student-built Tokamak reactor will be 3 × 3 feet in size and be the first such facility built for nuclear fusion in a university.

Australia is set to become home to the world’s first nuclear fusion facility designed, built, and operated by students. The project is planned by the University of New South Wales (UNSW) but will not use nuclear fuel, a press release said.

Nuclear fusion is the process where atoms of lighter elements like hydrogen are heated up to hundreds of millions of degrees Celsius to enable their fusion under large amounts of force. The process releases large amounts of energy, which can then be used to power devices and machines.

Meet the British Army’s new jet-propelled Hydra 400 drone

Posted by in categories: drones, security

The British Army has just showcased its next-generation, jet-propelled, heavy-lift Hydra 400 drone at this year’s DSEI conference in London.

The British Ministry of Defense (MoD) officially displayed its latest jet-propelled, heavy-lift drone at the Defence and Security Equipment International (DSEI) conference at the ExCeL center in London this September (2023). Called the Hydra 400, the British Army stand also featured the drone’s Aether mothership. A pioneering new generation of heavy-lift drones using hybrid propulsion technology (rotors and jet engines), the Hydra 400 is compact and portable, can be transported on a regular pickup truck, and can be prepared for flight in six minutes. It… More.

Webb telescope spots star spewing bright supersonic jets

Posted by in category: space

The space observatory has observed a dynamic environment around a young protostar as it accumulates mass on its path to becoming a Sun-like celestial body.

Since its launch, the advanced James Webb Space Telescope.

One example is star-forming regions, often challenging to observe due to their location within densely populated clouds of gas and dust.

US state seeks to outlaw the use of armed robots

Posted by in categories: drones, law enforcement, military, robotics/AI

The US military and its contractors would be exempt.

Robots that are autonomous or semi-autonomous and carry weapons or offensive capabilities are often called armed robots. These robots can be employed in a variety of settings, including the military, law enforcement, industry, and security.

Today, many armed robots are controlled remotely by human operators who can keep a safe distance between themselves and the devices. This is particularly prevalent with military drones, as the operators control the aircraft and its weaponry from a distance, making the machines even more dangerous to civilians.

Earth’s health is depleting on six of nine parameters

Posted by in categories: health, space

Human intervention right now holds the key.

How do we assess the health of our planet? In 2009, a group of 28 scientists wanted a definite answer to this question. So, they outlined nine planetary boundaries, which are critical for Earth’s stability.

A reassessment in 2023 says that six of these nine planetary boundaries have been transgressed, suggesting that Earth is “well outside of the safe operating space for humanity.”

Scientists kill brain cancer with quantum therapy in a first

Posted by in categories: neuroscience, quantum physics

Scientists propose a spray that will make the most aggressive brain cancer tumors commit suicide. This spray contains bio-nanoantennae, special molecules that can alter cells at the quantum level.

Scientists at the University of Nottingham have devised a unique spray treatment method to cure glioblastoma, a highly aggressive brain cancer that annually kills over 10,000 people in the US.

Underwater abode for deep-sea living open to public by 2027

Posted by in categories: habitats, innovation

The Sentinel system facilitates extended stays underwater, allowing scientists to reside at depths of up to 200 meters for as long as 28 days.

In a bold initiative, DEEP, a leading research organization, has announced plans to construct an underwater habitat open to the public by 2027. Named Sentinel, this modular subsea abode aims to revolutionize underwater living, research, and observation by providing scientists unprecedented access to the depths of the ocean.

The Sentinel system is designed to facilitate extended stays underwater, allowing scientists to reside at depths of up to 200 meters for as long as 28 days. This innovative habitat offers a unique opportunity for researchers to study… More.

TouchWind.

For years, the wind energy industry has adopted the three-blade model for its turbines. As the world looks for cleaner sources of energy, the turbines are getting larger and are also going deeper into the seas, where winds blow stronger.
