From the oxygen-carrying corpuscles in our blood to the branching neurons that govern our thoughts, our body is built of a dazzling variety of cells.

Researchers from institutions in Germany, Canada, Spain, and the US have published a comprehensive study of how many individual cells of each type there are in typical bodies.

Based on an exhaustive analysis of over 1,500 published sources, most adult males contain a total of around 36 trillion cells, while adult females tend to have some 28 trillion cells. A 10-year-old child, by comparison, would have in the region of 17 trillion.

Now, a YouTuber called Jay Bowles who goes by the name Plasma Channel built one and posted the process on his channel on Saturday. He started his video off by saying he was partially inspired to build the thruster by MIT’s model developed in 2018.

This version of the technology actually made a vehicle fly. “Their design was brilliant,” said Bowles in his video. “And it included aspects of a decades-old device called an ionic lifter.”

The universe is bigger than you think.

This means any deep-space future awaiting humanity outside our solar system will remain beyond the span of a single life until we develop a means of propulsion that outclasses conventional rockets. And, when three studies rocked the world earlier this year, it felt like a dream come true: Warp drive was no longer science fiction, potentially unlocking a theoretical basis to build faster-than-light warp drive engines that could cut a trip to Mars down to minutes.

However, a recent study shared in a preprint journal cast doubt on the theory, pointing to a gap in the math that could put the viability of a physical warp drive back into the realm of speculation.

A team of researchers led by Seung-Cheol Lee, director of the Indo-Korea Science and Technology Center(IKST) at the Korea Institute of Science and Technology (KIST), developed a method to predict the distribution of molecules on the surface using the magnetoresistance property of MXene, according to a statement by the scientists.

Autonomous underwater robots have been contracted to survey the site of the US’s first floating offshore wind farm.

In December, Norwegian energy giant Equinor won a 2-gigawatt (GW) lease in Morro Bay, California, in the first-ever offshore wind lease sale on the US West Coast. It was also the first US sale to support commercial-scale floating offshore wind development.

The Morro Bay project has the potential to generate enough energy to power around 750,000 US households.

Penn State researchers have recently harnessed the biological concept for application in artificial intelligence to develop the first artificial, multisensory integrated neuron, which may forever change the world of AI and robotics.

Associate professor of engineering science and mechanics at Penn State Saptarshi Das explains: “Robots make decisions based on the environment they are in, but their sensors do not generally talk to each other. A collective decision can be made through a sensor processing unit, but is that the most efficient or effective method? In the human brain, one sense can influence another and allow the person to better judge a situation.”

Quantum behavior is a strange, fragile thing that hovers on the edge of reality, between a world of possibility and a Universe of absolutes. In that mathematical haze lies the potential of quantum computing; the promise of devices that could quickly solve algorithms that would take classic computers too long to process.

For now, quantum computers are confined to cool rooms close to absolute zero (−273 degrees Celsius) where particles are less likely to tumble out of their critical quantum states.

Breaking through this temperature barrier to develop materials that still exhibit quantum properties at room temperatures has long been the goal of quantum computing. Though the low temperatures help keep the particle’s properties from collapsing out of their useful fog of possibility, the bulk and expense of the equipment limits their potential and ability to be scaled up for general use.
