Study says Northern Hemisphere lakes may lose 40 days of winter ice by 2100 (National Geographic photo) Winter ice on lakes plays an important role in keeping lakes healthy by controlling water temperature, supporting aquatic life and helping maintain the natural balance of freshwater ecosystems. However, scientists say this seasonal ice cover is disappearing faster…

“Do what you can do tomorrow, today,” says Roy Kim, a 13-year-old Oregon student who has solved the water crisis for numerous farmers in the region. The teenager developed a device that turns moisture in the air into water, helping farmers access a sustainable and reliable source of water in drought-prone areas, as per a…

The Massachusetts project is an example of agrivoltaics, a nascent farming practice that combines agriculture with solar energy generation on the same land. Farmers have relied on sunshine to grow healthy crops for generations. But as they say, excess of anything is bad and with climate change causing hotter summers, longer droughts and erratic weather,…

Ghana is transforming its plastic problems into paving blocks for its roads, sold below the price of concrete blocks. Behind this operation is Nelson Boateng, who graduated in computer network engineering, and was already manufacturing plastic bags and began transforming the same material into flooring. The plastic Ghana cannot contain Accra, the capital of Ghana…

More than 120 fish species have migrated from the Red Sea into the Mediterranean Since the Suez Canal opened more than 150 years ago, more than 120 fish species have migrated from the Red Sea into the Mediterranean. Researchers at Tel Aviv University have now created a statistical model that predicts which species are likely…

Concrete is the most widely used manufactured material on Earth, yet most people only ever encounter it once it has already hardened into a wall, a road or a slab. Science communicator Derek Muller set out to understand what the material actually does while it is still wet, by climbing into a tank of fresh…

“The present is theirs; the future, for which I really worked, is mine.” — Nikola Tesla (AI-generated image) Two inventors can watch someone else take credit for their work in real time and respond in completely different ways. One spends what energy remains fighting for immediate recognition, determined to win the argument before it’s too…

Rewilded elephants on Khamab Kalahari Reserve, who were observed during this research project (from left to right: Ngwedi, Mana, Michael, and Chikwenya) South Africa released 11 elephants that had spent years in captivity into protected reserves. Five years later, researchers found that their behavior was very similar to elephants that had always lived in the…

Representative Image of Europa’s hidden ocean beneath its icy surface (AI-generated image) Europa, one of Jupiter’s icy moons, may hold more liquid water than all of Earth’s oceans combined, sealed beneath a thick shell of ice. For years, one of the most promising ideas for studying that hidden ocean was that water rising through cracks…

Image Credit: inhabitat.com The global energy landscape is rapidly changing as the dangers of fossil fuels are becoming visible to researchers and the public. As traditional energy sources will probably diminish by the year 2088, the search for renewable options has expanded from wind and solar farms to personal, wearable technology. A prime example of…
