Water is present almost everywhere. It covers most of our planet, moves through the human body, and even settles into the tiniest molecular pockets. But what happens when water cannot circulate freely and becomes trapped inside these cramped spaces? Researchers at Karlsruhe Institute of Technology (KIT) and Constructor University in Bremen have now shown for…

Working with Alzheimer’s mouse models, human cells, and donated human brain tissue, researchers found that reducing levels of a molecule called PU.1 can shift microglia into a more protective mode. Microglia are immune cells that live in the brain and help maintain its health. When PU.1 levels drop, these cells increase the production of certain…

Loggerhead turtles are equipped with two different abilities for sensing the Earth’s magnetic field, yet scientists had not determined which one they rely on to interpret the magnetic map they inherit at birth. New findings from researchers at the University of North Carolina at Chapel Hill, published in Journal of Experimental Biology, show that hatchlings…

A geomagnetic superstorm is one of the most extreme forms of space weather, created when the Sun sends enormous bursts of energy and charged particles toward Earth. These powerful events rarely occur, typically appearing only once every 20-25 years. On May 10-11, 2024, Earth was hit by the strongest event of this kind in more…

University of California, Irvine astronomers have identified an exoplanet located within a star’s habitable zone, a region where temperatures could allow liquid water to exist on the surface. Liquid water is considered essential for every form of life currently known. The planet lies in a relatively nearby part of the Milky Way Galaxy and appears…

The COP30 climate summit fails to secure new pledges to cut fossil fuels after running over time for more than 18 hours. Source link

Georgina RannardClimate and science correspondent, Belém, Brazil EPA Following bitter rows, the UN climate summit COP30 in Belém, Brazil has ended with a deal that contains no direct reference to the fossil fuels that are heating up the planet. It is a frustrating end for more than 80 countries including the UK and EU that…

Every spring, the familiar songs of Wood Thrushes and warblers drift back into parks and neighborhoods across eastern North America. Few people realize that these birds spend most of their lives much farther south, relying on the lush and often remote forests of Central America to survive the rest of the year. A recent study…
