What is Dark Energy? A mysterious substance that fills space and causes it to expand is Dark Energy .70% of the universe’s energy is in the form of ‘dark energy’
Centenarians have become the fastest-growing demographic group in the world, with numbers approximately doubling every 10 years since the 1970s.
Many researchers have sought out the factors and contributors that determine a long and healthy life. The dissolution isn’t new either, with Plato and Aristotle writing about the ageing process over 2,300 years ago.
Understanding what is behind living a longer life involves unravelling the complex interplay of genetic predisposition and lifestyle factors and how they interact.

Earth’s H2O is 97 percent seawater, and most of the remaining 3 percent is inaccessible, frozen in glaciers or permafrost. Only a small portion, about half of a percent, exists as freshwater in aquifers and rivers that humans can tap into. A process called, however, allows us to dip into the oceans to satisfy our thirst.
Desal has been around for decades and is used to make both seawater and salty groundwater drinkable. But scientists think that it will become increasingly important in a warmer, drier future. In a recent UN-led review, researchers stated that “‘conventional’ sources of water such as rainfall, snowmelt and river runoff captured in lakes, rivers, and aquifers are no longer sufficient to meet human demands in water-scarce areas.”
During a media roundtable at the 2019 American Geophysical Union conference, Peter Fiske, director of the Water-Energy Resilience Research Institute at Lawrence Berkeley National Laboratory, discussed why we might need to more strongly consider this technology—at times written off for its high costs and energy use—to stabilize water supplies in the future. Here’s what you need to know.

In late 2019, the previously unremarkable galaxy SDSS1335+0728 unexpectedly brightened, prompting astronomers to investigate the cause using data from various observatories, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT).
The study, recently published in the journal Astronomy & Astrophysics, suggests an unprecedented event: the sudden awakening of the massive black hole at the galaxy’s core.
“Imagine you’ve been observing a distant galaxy for years, and it always seemed calm and inactive,” said Paula Sánchez Sáez, an astronomer at ESO.
The cosmos has always fascinated scientists, and NASA’s James Webb Space Telescope (JWST) is now offering unprecedented views of supernovae from the early universe.
Recently, a team of researchers used Webb’s data to identify ten times more supernovae than were previously known, uncovering some of the most distant examples ever observed.
These findings, presented at the 244th meeting of the American Astronomical Society in Madison, Wisconsin, are revolutionizing our understanding of the universe’s expansion.
Good health depends on a healthy diet and sufficient exercise and sleep. There are clear associations among these components; for example, good nutrition provides energy for exercise, and many people report that getting enough exercise is important to their ability to get enough sleep. So how might nutrition affect sleep?
A new study looks at the connection between fruit and vegetable intake and sleep duration. The research, by a team from Finland’s University of Helsinki, National Institute for Health and Welfare, and Turku University of Applied Sciences, is published in Frontiers in Nutrition.
Why sleep is important and how it works Sleep gives our bodies the chance to rest and recover from wakeful activity. Our hearts, blood vessels, muscles, cells, immune systems, cognitive abilities, and memory-making abilities depend on regular, healthy sleep for optimal functioning, and a 2019 study suggests that sleep is important for repairing DNA damage that occurs during wakefulness.
