The Pentagon has announced a new four-star military command that will focus on quickly developing and using killer robots and other weapons that can operate on their own.

The announcement was made by US Defense Secretary Pete Hegseth during his “State of the Force” speech on Wednesday at the Quantico Marine base in Virginia.

The new command is expected to help the US military adopt advanced technology faster and improve its ability to use autonomous weapons in future wars.

Autonomous weapons are machines that can carry out certain military tasks with little or no human control.

These weapons may include robots, drones, and other systems that can identify targets and carry out attacks.

Supporters believe such technology could help soldiers stay away from dangerous battlefields and allow military operations to happen more quickly.

However, the growing use of these weapons has raised serious concerns about safety, responsibility, and human control.

One major question is whether a machine should be allowed to decide who lives and who dies during a war.

If an autonomous weapon makes a mistake and attacks innocent people, it may be difficult to decide who should be held responsible.

Amnesty International, a human rights organisation, has called for a complete ban on killer robots.

The organisation has warned that replacing soldiers with machines could make it easier for governments to start wars because fewer human lives would be directly at risk.

Experts and human rights groups are concerned that this technology could make conflicts more dangerous and harder to control.

As countries continue developing military artificial intelligence, the debate over killer robots is likely to grow.

The main challenge will be balancing military progress with human safety, responsibility, and international law.

Solar power above, grazing cows below! ☀️🐄

A dairy farm in France is combining farming with clean energy using 5,184 solar panels installed about 16 feet above the ground. Cows can graze underneath while the panels generate renewable electricity. 🌱⚡

Known as agrivoltaics, this approach allows the same land to support both agriculture and solar power. The elevated panels can also offer livestock shade during hot weather, while their effects on grass growth and soil moisture depend on local conditions and system design.

With thoughtful planning, farms can produce food and electricity side by side.

Tesla has revealed its new Roadster, an electric sports car that appears to be capable of flying into the air.

The car was shown performing amazing moves in the air using special technology developed with SpaceX.

It uses small devices called cold-gas thrusters, which release gas to create force and help the car move in different directions.

This technology could give the Roadster a completely new level of speed and performance.

Unlike normal sports cars, this futuristic vehicle is designed to push the limits of what a car can do.

The demonstration was part of the long-awaited reveal of Tesla's next-generation Roadster.

Tesla has been working on this electric sports car for years, and people have been waiting eagerly to see what it can offer.

The use of SpaceX technology has made the car even more exciting because it brings ideas from space engineering into the world of cars.

However, the airborne demonstration does not mean that the Roadster can fly like an aircraft or travel through the sky freely.

Its special thrusters are designed to improve performance, but the exact capabilities of the production car will depend on its final design.

If this technology works as expected, it could change how people think about future sports cars.

It also shows how electric vehicles may become more advanced as engineers develop new technologies.

For now, the idea of a car that can rise into the air sounds like something from a science-fiction movie.

But with Tesla exploring such technology, we might actually be living in the future.

A statue of US President Donald Trump called “The Orange Plague” was displayed inside the European Parliament building in Strasbourg, France.

The 8.5-foot-tall copper statue was created by Danish artist Jens Galschiot and is also known as the “King of Injustice.”

The statue shows Trump sitting on the shoulders of a smaller man.

It stands on a platform with a message criticizing leaders who claim to help people but continue to put pressure on them.

The message says that Trump is sitting on another man's back while claiming to help him, but refuses to step down and make things easier.

According to the artist, the statue was covered with 23-karat gold leaf, giving it a shiny golden appearance.

The artwork was inspired by the famous fairy tale The Emperor's New Clothes by Hans Christian Andersen.

In the story, an emperor believes he is wearing beautiful clothes, but he is actually naked.

Galschiot said Trump believes that gold makes him look powerful and important, but it only makes his nakedness more visible.

The exhibition was sponsored by Danish politician Per Clausen.

He said Trump's actions were creating serious problems for people across Europe.

Clausen wanted the exhibition to encourage Europeans to discuss how they could protect themselves from Trump's influence.

He also called for European leaders to develop policies that do not depend on Trump.

The statue uses humour and criticism to raise questions about power, leadership, and political responsibility.

Developers showed a Dutch-Belgian technology news website called Tweakers how a new government computer system works behind the scenes.

The system is called the Digital Autonomous Government Work Environment, or DAWO.

It is already being used on a small scale by some government agencies in the Netherlands.

DAWO is designed to give government workers a reliable and well-organized computer system.

The system is based on NixOS, a Linux-based operating system developed in the Netherlands.

NixOS uses a special tool called the Nix package manager to install and manage software.

This tool helps computers keep their software and settings organized.

It also makes it easier to set up several computers in the same way.

This is important for government offices because they need computers that work reliably and follow the same rules.

The Nix package manager can run on different systems, including Linux, Unix, and macOS.

It can also work on Windows through a feature called Windows Subsystem for Linux, or WSL.

This feature allows people to use Linux tools on a Windows computer without replacing Windows.

Using NixOS could help government agencies manage their computers more easily.

It may also make software updates and system maintenance simpler.

However, DAWO is still being used on a limited scale.

Its wider use will depend on how well it works in real government offices.

If successful, the project could help Dutch government agencies build a more consistent and manageable digital workplace.

A woman in Auckland, New Zealand, was sentenced to two months in jail after her dog, Nuggi, died because of extreme obesity.

The woman told animal welfare officers that she fed Nuggi eight to ten pieces of chicken every day, along with his regular dog biscuits.

In 2021, Nuggi was found weighing nearly 120 pounds (54 kilograms).

He was so overweight that he could barely move around.

His body had become extremely unhealthy because of his excessive weight.

The case shocked animal welfare workers, who believed that his condition was among the worst they had ever seen.

After investigating the case, the court punished the woman for failing to take proper care of her dog.

Apart from spending two months in jail, she was ordered to pay $1,222.15 in compensation.

She was also banned from owning animals in the future.

Later, a detailed examination of Nuggi's body revealed that he had other serious health problems.

He was suffering from liver disease and Cushing's disease, a condition that can affect hormone levels and cause weight gain.

These illnesses made his health even worse.

The chief executive of the Society for the Prevention of Cruelty to Animals (SPCA) said Nuggi was one of the most obese animals they had ever encountered.

The case highlights how important it is to feed pets the right amount of food and provide them with proper care.

Overfeeding a dog may seem harmless, but it can lead to serious health problems and even death.

Pet owners must ensure their animals maintain a healthy weight and receive veterinary care when needed.

Scientists have detected a radio signal coming from a planet outside our solar system for the first time in scientific history.

This discovery is an important step toward understanding distant planets and finding out whether life could exist beyond Earth.

The research was carried out by a team of scientists who study space and distant planets.

Radio signals are waves of energy that travel through space and can be detected using special telescopes.

By studying these signals, scientists can learn more about a planet's atmosphere, magnetic field, and other important features.

A planet's magnetic field helps protect it from harmful particles coming from its nearby star.

Studying these magnetic fields can also help scientists understand whether a planet has conditions that might support life.

Until now, scientists have faced many challenges in studying planets outside our solar system because they are extremely far away.

These planets are called exoplanets, and thousands of them have already been discovered.

However, detecting radio signals from such distant worlds is difficult because the signals are often very weak.

This new discovery could help researchers develop better ways to study exoplanets in the future.

It may also help scientists identify planets with conditions suitable for living organisms.

However, finding a radio signal does not mean that life has been discovered on another planet.

More research is needed to understand the signal and confirm what it tells us about the planet.

Scientists hope that future discoveries will bring us closer to answering one of humanity's biggest questions: Are we alone in the universe?
