Healthy Reef Sounds Could Help Restore Coral Reefs

-
Image
Healthy coral reefs may have more than beauty working in their favor. They also have a distinctive underwater soundtrack. New research suggests that reproducing the sounds of a thriving reef can help attract young coral and fish to degraded underwater habitats, potentially giving marine restoration projects a new tool for rebuilding damaged ecosystems. The finding is important because coral reef restoration is no longer simply about putting coral fragments back onto a damaged reef. Scientists are increasingly looking at the biological signals that help young marine animals decide where to settle. Among those signals, the underwater soundscape may be surprisingly powerful. Two new studies led by scientists at the Scripps Institution of Oceanography at UC San Diego investigated how acoustic enrichment could support both coral larvae and fish communities. The research combines underwater sound playback with other restoration technologies, including engineered settlement structures a...

2,000-Year-Old Ring Reveals Alexandria’s Lost Lighthouse

-
Image
A tiny bronze ring recovered from the submerged ruins of ancient Alexandria is giving archaeologists an extraordinary new clue about one of antiquity’s most famous monuments: the Lighthouse of Alexandria , also known as the Pharos. The approximately 2,000-year-old seal ring carries a small engraved image that researchers identify as a representation of the lost lighthouse. Egyptian archaeological authorities describe the object as exceptional because this is reportedly the first known example of the Lighthouse of Alexandria appearing on a seal ring. The discovery was made during underwater archaeological excavations in Alexandria’s ancient Eastern Harbour, specifically around the submerged royal island of Antirhodos. The location is important because the island once formed part of the city’s royal quarter and was associated with a palace described by the ancient geographer Strabo. A Tiny Bronze Ring With a Monumental Image At first glance, the newly discovered object is much le...

Stanford Cancer ‘Kill Switch’ Targets Lymphoma

-
Image
A new approach to cancer treatment from Stanford Medicine is attracting attention because it does something unusual: instead of simply blocking a protein that helps cancer grow, researchers have redesigned that cancer-driving protein so it helps trigger the death of cancer cells. The experimental strategy targets BCL6 , a protein strongly associated with certain B-cell lymphomas. Researchers created a two-part molecule called TCIP3 that redirects BCL6 toward activating genes involved in programmed cell death. In experiments involving aggressive human lymphoma tumors grown in mice, twice-daily treatment eliminated the tumors within 11 days. The findings could represent an important new direction in targeted cancer therapy. However, the results are still preclinical. The molecule has not been established as a treatment for people, and extensive laboratory, safety and clinical testing would be required before it could potentially become a cancer medicine. How the Stanford Cancer “K...

El Niño 2026: What Portugal’s Coast Should Expect

-
Image
A major climate development is attracting global attention in October 2026: the current El Niño event is strengthening and is expected to remain in place through February 2027. The World Meteorological Organization (WMO) says there is an exceptionally high likelihood, close to 100%, that El Niño will persist through the Northern Hemisphere winter. For people living in or visiting Portugal, however, one important distinction matters: El Niño does not automatically mean extreme weather in Portugal . Portugal's national meteorological institute, IPMA, says the effects of El Niño on Portugal are not direct and are not statistically significant enough to treat the phenomenon as a precise local forecast. This does not make the story irrelevant. El Niño changes large-scale atmospheric circulation, ocean temperatures and rainfall patterns around the world. Those changes can interact with other climate drivers affecting the Iberian Peninsula and the Atlantic. For coastal cities and hol...

Asteroids and Earth: What Could Happen by 2030?

-
Image
Could an asteroid really collide with Earth? Astronomers say yes — theoretically and physically, it is possible. But that does not mean that a major asteroid impact is expected to happen by 2030. The difference between a mathematical possibility and a confirmed danger is extremely important when discussing near-Earth objects. Every day, Earth travels through a Solar System filled with dust, fragments of rock, artificial debris, comets and asteroids. Most of this material is tiny and harmless. Some particles enter the atmosphere and produce shooting stars, while larger objects can survive as meteorites. Much larger asteroids can pass near Earth without hitting it. Modern astronomy is designed to distinguish between these situations. Scientists continuously observe near-Earth asteroids, calculate their orbits and update impact probabilities when new observations become available. Can an Asteroid Hit Earth by 2030? The short answer is that an impact is physically possible, but there is n...

African Lion Alpha Males: Life on Guard

-
Image
On the African savanna, an adult male lion rarely enjoys a truly quiet life. Even when he appears to be sleeping beneath a tree, his survival may depend on what happens around him. Rival males can approach, hyenas can challenge a pride, prey can disappear with the changing seasons, and younger males may eventually attempt to take control. The image of an alpha male lion standing on a rocky outcrop, watching the horizon, captures something real about lion society. But the idea of a single male ruling a pride like a king is too simple. In the wild, male lions often operate as partnerships called coalitions . Their success depends on cooperation, physical condition, territory, social relationships and the ability to defend access to females. This is what makes the life of an African male lion so fascinating. Strength matters, but strength alone is not enough. Why Do Male Lions Fight for Control? African lions ( Panthera leo ) are unusual among big cats because they are highly soc...

Earth’s Inner Core Is Moving: What It Means for Us

-
Image
What if the deepest part of Earth is moving in a way that can slightly change the length of our day? This is not science fiction. Modern seismology shows that Earth’s solid inner core can move differently from the mantle and crust surrounding it. Scientists cannot travel thousands of kilometres underground to watch this movement directly, so they use earthquakes, seismic waves, Earth-rotation measurements and mathematical models to reconstruct what is happening. A major study published in Nature on September 23, 2026 , provides new evidence that gravitational interactions involving the inner core help explain long-term variations in the length of Earth's day. The research connects changes in inner-core rotation, fluid motion in the outer core and forces acting between Earth's deep layers. The fascinating part is that the numbers sound complicated until we translate them into something the human brain can understand. Is the Center of Earth Really Moving? The short answe...
