The future of corals – what X-rays can tell us

Researchers at Oregon State University found that bat rays produce a chemical cue to alert other rays of potential danger. The study used three tanks with individual bat rays and simulated a predator in one tank, causing the other rays to exhibit a flight response.

A recent FAU study reveals that mesophotic corals can replenish declining shallow reef populations with strong genetic connectivity between shallow and deep zones. The research suggests that deeper corals could be a key source of genetic diversity for shallow reefs, providing valuable opportunities for recovery and restoration efforts.

A research team found that ancient corals from the Middle Devonian period, over 385 million years ago, had symbiotic algae that carried out photosynthesis. This discovery provides geochemical evidence of the oldest confirmed photosymbiosis in corals and sheds light on the nutrient cycle of Paleozoic-era reefs.

New research demonstrates that corals naturally thriving in extreme environments can be used to boost the resilience of reef sites. Despite being transplanted to more stable conditions, these corals retained their heat tolerance and activated pathways associated with DNA repair and homeostasis.

Researchers at NTU Singapore create a new, eco-friendly sunscreen from Camellia flowers that blocks UV rays without harming corals. The pollen-based gel demonstrates comparable or superior UV protection to commercial sunscreens and regulates skin temperature more effectively.

Researchers found that a chlorine-cocoa butter mixture can effectively treat diseased corals, reducing tissue loss and environmental harm. The alternative approach offers a cheaper, biodegradable solution to combat antibiotic-resistant bacteria.
