What If WW3 Starts Tomorrow? | The 5 Things You Must Do in the First 24 Hours

It’s 3:43 AM. Sirens are howling. Your phone lights up: DEFCON 1. Multiple ICBMs inbound.

World War 3 has just begun.

Would you know what to do in the first minutes? Most people freeze. This guide is for those who act.

In this video, we walk you through the real first steps to take if global war breaks out — not theory, not panic, but practical survival strategy for the first 24 hours: from identifying if you’re in a high-risk zone, to securing water and food, to communicating with loved ones when the grid is down.

💥 Whether it’s a nuclear attack, an EMP, or a cyber blitz — this is what you need to know before it’s too late.

Topics we cover include:

This Common Blood Pressure Drug Extends Lifespan, Slows Aging in Animals

The hypertension drug rilmenidine has been shown to slow down aging in worms, an effect that in humans could hypothetically help us live longer and keep us healthier in our latter years.

Previous research has shown rilmenidine mimics the effects of caloric restriction on a cellular level. Reducing available energy while maintaining nutrition within the body has been shown to extend lifespans in several animal models.

Whether this translates to human biology, or is a potential risk to our health, is a topic of ongoing debate. Finding ways to achieve the same benefits without the costs of extreme calorie cutting could lead to new ways to improve health in old age.

Early-life to endocrine-disrupting chemicals may fuel food preferences

Exposure to endocrine-disrupting chemicals in early life, including during gestation and infancy, results in a higher preference for sugary and fatty foods later in life, according to an animal study being presented Sunday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif.

Endocrine-disrupting chemicals are substances in the environment (air, soil or water supply), food sources, personal care products and manufactured products that interfere with the normal function of the body’s endocrine system. To determine if early-life exposure to these chemicals affects eating behaviors and preferences, researchers from the University of Texas at Austin conducted a study of 15 male and 15 female rats exposed to a common mixture of these chemicals during gestation or infancy.

“Our research indicates that endocrine-disrupting chemicals can physically alter the brain’s pathways that control reward preference and eating behavior. These results may partially explain increasing rates of obesity around the world,” said Emily N. Hilz, Ph.D., a postdoctoral research fellow at the University of Texas at Austin in Austin, Texas.

New biodegradable plastic shines in vibrant colors without dyes or pigments

Plastics are one of the largest sources of pollution on Earth, lasting for years on land or in water. But a new type of brilliantly colored cellulose-based plastic detailed in ACS Nano could change that. By adding citric acid and squid ink to a cellulose-based polymer, researchers created a variety of structurally colored plastics that were comparable in strength to traditional plastics, but made from natural biodegradable ingredients and easily recycled using water.

Many plastics are dyed using specialized colorants, which can make these materials hard to recycle using typical processes. Over time, dyes can fade or leach into the environment, posing risks to wildlife. One way to make these colorants largely unnecessary could be a phenomenon called . This occurs when tiny structures in a material reflect certain wavelengths of light rather than a dye or pigment molecule. Structural color gives peacock feathers and butterfly wings their vibrant hues and dazzling shine, but certain display structural color as well.

Hydroxypropyl cellulose (HPC), a derivative of cellulose often used in foods and pharmaceuticals, is one example of a material that can display structural color. In , it shines in iridescent tones, but its have historically made it difficult to form into a solid plastic. Researchers Lei Hou, Peiyi Wu and colleagues wanted to see if they could fine-tune the chemistry of HPC to create vibrant, structurally colored plastics that worked as well as existing petroleum-based plastics and were environmentally friendly.

Bifacial thin-film solar cells harness sunlight from both sides for higher output

A research team successfully implemented CuInSe2 thin-film solar cells composed of copper (Cu), indium (In), and selenium (Se) on transparent electrode substrates. Furthermore, the team developed a “bifacial solar cell technology” that receives sunlight from both the front and back sides to generate power. This technology can be fabricated at low temperatures, enabling a simpler production process, and is broadly applicable to building-integrated solar power, agricultural solar power, and high-efficiency tandem solar cells in the future.

New approach allows drone swarms to autonomously navigate complex environments at high speed

Unmanned aerial vehicles (UAVs), commonly known as drones, are now widely used worldwide to tackle various real-world tasks, including filming videos for various purposes, monitoring crops or other environments from above, assessing disaster zones, and conducting military operations. Despite their widespread use, most existing drones either need to be fully or partly operated by human agents.

In addition, many drones are unable to navigate cluttered, crowded or unknown environments without colliding with nearby objects. Those that can navigate these environments typically rely on expensive or bulky components, such as advanced sensors, graphics processing units (GPUs) or .

Researchers at Shanghai Jiao Tong University have recently introduced a new insect-inspired approach that could enable teams of multiple drones to autonomously navigate complex environments while moving at high speed. Their proposed approach, introduced in a paper published in Nature Machine Intelligence, relies on both a deep learning algorithm and core physics principles.

Genetically modified gut bacteria show promise for combating kidney stones in clinical trial

The human gut microbiome has been shown to impact health in a myriad of ways. The type and abundance of different bacteria can impact everything from the immune system to the nervous system. Now, researchers at Stanford University are taking advantage of the microbiome’s potential for fighting disease by genetically modifying certain bacteria to reduce a substance that causes kidney stones. If scientists are successful at modifying gut bacteria, this can lead to therapeutic treatments for a wide range of diseases.

However, the study, published in Science, shows that this is not a simple task. The researchers used the bacterium Phocaeicola vulgatus, which is already found in the microbiome of humans, and modified it to break down and also to consume porphyran, a nutrient derived from seaweed. The porphyran was used as a way to control the population of Phocaeicola vulgatus by either adding more porphyran or reducing the amount, which should kill off the bacteria due to a lack of food.

The study was made up of three parts: one testing the modified bacteria on rats, one trial with healthy humans and one trial on people with enteric hyperoxaluria (EH). EH is a condition in which the body absorbs too much oxalate from food, leading to and other kidney issues, if not treated.
