How Cape Town Solved Their Water Crisis
In January 2018, Cape Town declared a national emergency. The South African city of 4 million people was three months away from running out of municipal water. Three years on, the city’s dams are now 100% full and water use restrictions have since been relaxed. Here's how they did it, and what the world can learn from them.
The Fall Equinox Starts This Weekend - Here's What It Means for Your Day
The arrival of the fall equinox marks the official start of the autumn season in the Northern Hemisphere. During this special moment, Earth's axis aligns with its orbit, ensuring that both the northern and southern hemispheres receive nearly equal amounts of sunlight. This alignment results in day and night lasting almost the same duration, a phenomenon that gives the equinox its name, derived from Latin words meaning "equal" and "night."
How This AI-Powered Bird Migration Tracker is Saving Bird Lives
BirdCast, an AI-powered tracking technology developed by researchers at Cornell University, is helping to protect migratory birds and mitigate the impact of human activities on them. BirdCast uses radar data from the National Weather Service to monitor and predict the movements of birds during their migrations, providing real-time information to cities and organizations. By forecasting bird migrations and alerting communities to turn off lights, BirdCast has reduced bird fatalities and it has also been used to help predict avian flu outbreaks.
San Diego is Closing a Beach for Seven Years to Protect the Sea Lion Population
The San Diego City Council has unanimously voted to close Point La Jolla and parts of nearby Boomer Beach for seven years to protect the local sea lion population from human disturbances. he closure, spanning about 150 yards of coastline, aims to provide a safe space for sea lions to give birth, nurse, and breed without human interference. Visitors will still be able to observe the marine mammals behind barriers, and ocean access from the closed area will remain open.
How a High School Class Helped NASA Discover a Space Mystery
High school teacher Jonathan Swift and his students observed unexpected changes in the behavior of the asteroid Dimorphos following NASA's intentional crash into it during the DART mission. Dimorphos, which orbits its parent asteroid Didymos, appeared to be tumbling in its orbit and continuously slowing down for at least a month after the impact, contrary to NASA's predictions. The class's observations brought attention to these findings, and the DART team is planning to release more information, with further investigation scheduled for 2026 .
Global Rhino Numbers Are Rebounding in a Conservation Win

A New Study Shows Human Cells Display a Mathematical Pattern That Repeats in Nature
After more than a decade of research, scientists have estimated the number of cells in the human body. Their findings reveal that men have around 36 trillion cells, women have about 28 trillion, and a 10-year-old child has roughly 17 trillion cells. What's intriguing is that these cells follow a mathematical pattern based on size and mass, mirroring patterns found in other areas of science and nature. The study may offer valuable insights into understanding human health and diseases, particularly cancer, by shedding light on cell frequencies and counts.
