New Low-Power Desalination Technology
Water, water everywhere, nor any drop to drink! KISS on a boat Living on a boat as I do, obtaining fresh water is a problem. I try to follow the KISS principle and so I’ve avoided the complexities associated with power-hungry marine desalination systems.

Dark Matter
The study of "dark matter" is one of the most intriguing and mysterious areas of modern physics. Despite its name, dark matter is not actually "dark" in the traditional sense of the word. Rather, it is a type of matter that does not interact with light or other forms of electromagnetic radiation in the way that normal matter does. As a result, it is invisible to telescopes and other instruments that are used to study the universe. But despite its invisibility, scientists believe that dark matter plays a crucial role in the formation and evolution of galaxies, as well as in the overall structure of the universe. The existence of dark matter was first proposed in the 1930s by Swiss astronomer Fritz Zwicky, who observed that the total mass of galaxy clusters was not sufficient to account for the gravitational forces holding them together. Since then, numerous studies have provided evidence for the existence of dark matter. One of the key reasons scientists believe in the existence of dark matter is the fact that the universe appears to contain far more matter than we can see. According to astronomical observations, the universe contains five times more matter than can be accounted for by the "normal" matter that we can see, such as stars, planets, and galaxies. This missing matter is thought to be made up of dark matter. The existence of dark matter is inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. For example, the rotation curves of spiral galaxies suggest that they contain far more mass than can be accounted for by the visible stars and gas. Similarly, the temperature fluctuations of the cosmic microwave background radiation suggest that there is more matter in the universe than we can see. The study of Cosmic Microwave Background radiation by the Planck spacecraft, also supports the existence of dark matter and dark energy. One of the most popular theories about dark matter is that it is made up of "Weakly Interacting Massive Particles" (WIMPs). These particles are thought to interact only through gravity and the weak nuclear force, which makes them difficult to detect. However, scientists have been searching for WIMPs using underground detectors and particle accelerators in the hopes of detecting these elusive particles. The Large Hadron Collider (LHC) at CERN, is currently one of the major experiments looking for WIMPs. Another theory is that dark matter could be composed of primordial black holes, that formed shortly after the Big Bang. These black holes would be much smaller than the ones we see today, and they could be detected by their gravitational effects on nearby matter. The LIGO and Virgo gravitational wave detectors have also been used to search for primordial black holes. The study of dark matter also has potential implications for our understanding of the Earth. Scientists have proposed that dark matter could be responsible for the mysterious "Earth hum" phenomenon, a low-frequency noise that has been reported in various locations around the world. According to this theory, the Earth's rotation could be causing dark matter particles to collide and produce the hum. However, this theory is still highly speculative and more research is needed to confirm or disprove it. In conclusion, dark matter is one of the most mysterious and intriguing areas of modern physics. Despite its invisibility, scientists believe that dark matter plays a crucial role in the formation and evolution of galaxies, as well as in the overall structure of the universe. The study of dark matter is ongoing, with scientists searching for evidence of its existence and trying to understand its properties using various experiments and observation methods. The potential implications of dark matter's existence are far-reaching, and it could have a profound impact on our understanding of the universe, the Earth, and its environment. The study of dark matter is a reminder of the vastness and complexity of our universe, and how much we have yet to discover and understand about it. It also highlights the importance of interdisciplinary research and international collaboration in making progress in this field. The search for dark matter is not only a scientific quest but also a technological one, as it requires the development of more sensitive and advanced detectors and instruments. As we continue to explore the universe, it is important to keep an open mind and consider all possibilities, in order to fully understand the mysteries of dark matter and its impact on our world.

First polio campaign of the year begins today
Today marks the beginning of the first polio campaign of the year, aimed at reaching and vaccinating children under the age of five against the debilitating and potentially deadly disease. The World Health Organization (WHO) and its partners, including UNICEF and the Centers for Disease Control and Prevention (CDC), will be working to vaccinate children in high-risk areas across the globe in an effort to eradicate the disease once and for all.

The Changing Face of Weather: Understanding and Adapting to Our Climate
Introduction: Climate change is one of the most pressing issues of our time, and the effects of a changing climate can be seen in the weather patterns all around us. From heat waves to hurricanes, droughts to floods, it's clear that the weather is becoming more extreme and unpredictable. It's a well-established scientific fact that the Earth's climate is warming and that human activities, such as burning fossil fuels and deforestation, are the main cause of this warming. In this blog post, we will delve into the science behind these changes and discuss the impact on weather patterns. We will also talk about the steps that individuals, communities and governments can take to adapt to a new normal.

Why is the Arctic warming so much faster? New
The Arctic is warming at a faster rate than the rest of the planet due to a phenomenon known as Arctic amplification. This occurs because as the polar regions warm, ice and snow melt, exposing darker land and water surfaces that absorb more solar radiation, causing even more warming. Additionally, the loss of sea ice in the Arctic can also cause more warming by altering ocean currents and weather patterns. Greenhouse gases are the main driver of this warming, with the majority of the warming caused by carbon dioxide emissions from human activities.

World Without US
Sages meditated for Ages; the wise-men wrote millions of pages; kings and statesmen gave brilliant speeches—about joy and happiness, that has eluded the mankind in the known history. What a profound mystery! The pages of human history, daubed in bloodshed, very recently that of World War I & II and Nanking (China) ask the crying question. How to make this Planet Earth, heaven-like? The answer is simple and direct. Eyes full of understanding, the heart full of love and the life that refuses conflicts—enough. These alone are enough. Well, if peace is not possible for humanity, what is the alternative? Alan Weisman seems to have the answer.
