Today weâre going explore the unthinkable: How would the United States respond during a Nuclear conflict?
When we first came up with this concept, we aimed to cover the Americaâs Nuclear Triad and itâs Russian Nuclear War Plan in one concise video, but one video turned into three. So hereâs full version of âHow Would the United States Fight a Nuclear War?â as it was originally intended. Enjoy!

Venus is one of the most brutally inhospitable places in our solar system, but many scientists think life may have thrived there at one point. Hereâs why.
The James Webb Space Telescope has delivered yet another astounding discovery, spying an active supermassive black hole deeper into the universe than has ever been recorded.
The black hole lies within CEERS 1,019 â an extremely old galaxy likely formed 570 million years after the big bang â making it more than 13 billion years old. And scientists were perplexed to find just how small the celestial objectâs central black hole measures.
âThis black hole clocks in at about 9 million solar masses,â according to a NASA news release. A solar mass is a unit equivalent to the mass of the sun in our home solar system â which is about 333,000 times larger than the Earth.
To avert the extremely remote risk that debris poses to life, ESA is targeting the reentry at a vast expanse of ocean far away from land.
If the manoeuvres are successful, ESA expects to complete the journey in late July or early August. However, as a first-ever attempt at an assisted reentry, itâs not guaranteed to work. If the plan has to be aborted, Aeolusâ natural descent will continue.
But if the mission is accomplished, it will set a new standard for satellite reentry and space junk mitigation.
AI had its nuclear bomb threshold. The biggest thing that happens to human technology maybe since the splitting of the atom.

Pulsar Fusion has begun construction of the worldâs largest rocket engine, which will be fuelled by fusion. Within four years, the British company intends to create an 8-metre-long combustion chamber.
Hereâs What We Know
The fusion engine will be based on a very hot plasma trapped inside an electromagnetic field. Now scientists are working on how to keep the plasma in the electromagnetic field. The announcement was made by James Lambert, CFO of the UK-based company.
A small selection of volunteers who were completely color blind can now faintly detect a splash of color following retinal gene therapy.
Following the trial by researchers in Israel, three adults and one child who could only sense brightness of light found that after gene therapy they were able to tell a red object apart from its darker background.
Achromatopsia is caused by defects in genes that control cone cells, our eyesâ color-sensors. The approximately 1 in 30,000 people affected see all the vibrant colors of the world as blurry shades of gray.
Long-lived fungi are the latest organisms to go under the microscope in search of new understandings as to why they donât accrue life-limiting mutations, given their age.
Researchers at Wageningen University in the Netherlands set out to compare âthe peculiaritiesâ of multicellular growth in filamentous fungi. What they ended up with was a new hypothesis explaining how certain types of fungi keep a lid on freeloading mutations that accumulate in their thread-like mycelia; the root-like structures of fungal colonies.
The filaments of mushroom-forming fungi spend much of their long lives with two, separate nuclei, each containing one-half of a full set of chromosomes. Only in the gills of mushrooms moments before forming spores do the two haploid nuclei mesh together in a brief union to reproduce asexually.
In a study published recently in Advanced Intelligent Systems, researchers from Queen Mary University of London have made significant advancements in the field of bionics with the development of a new type of electric variable-stiffness artificial muscle that possesses self-sensing capabilities. This innovative technology has the potential to revolutionize soft robotics and medical applications.
Muscle contraction hardening is not only essential for enhancing strength but also enables rapid reactions in living organisms. Taking inspiration from nature, the team of researchers at QMULâs School of Engineering and Materials Science has successfully created an artificial muscle that seamlessly transitions between soft and hard states while also possessing the remarkable ability to sense forces and deformations.
Dr. Ketao Zhang, a Lecturer at Queen Mary and the lead researcher, explains the importance of variable stiffness technology in artificial muscle-like actuators. âEmpowering robots, especially those made from flexible materials, with self-sensing capabilities is a pivotal step towards true bionic intelligence,â says Dr. Zhang.
