Decades-Old Barrels of Industrial Waste Still Impacting Ocean Floor Off LA

New research from UC San Diego's Scripps Institution of Oceanography reveals that barrels with halos - previously thought to contain the pesticide DDT - contain caustic alkaline waste.

Ocean Warming Projected to Stall Expected Mangrove Recovery

Increasing ocean temperatures will erase mangrove restoration gains, according to new research. Scripps Oceanography scientists and colleagues project that by 2100 the world would lose out on 150,000 hectares (370,000 acres) of mangroves and associated ecosystem services worth $28 billion annually.

New Database Expands Understanding of Pacific Coral Reef Fish

Marine biologists at UC San Diego’s Scripps Institution of Oceanography have released a new database of size parameters for 1,308 species of Pacific coral reef fishes, advancing scientists’ understanding of fish health and population dynamics in the region.

Weathering Change: Fewer Cold Fatalities, More Heat Emergencies in California

Rising temperatures in California are causing fewer cold-related deaths, outweighing heat-related deaths. However, hotter temperatures significantly increases emergency department visits – a previously overlooked consequence of climate change that could place greater burden on the healthcare system.

Wildfire Science & Technology Commons Opens to the Public to Unite and Accelerate Wildfire Solutions

A team of University of California San Diego researchers has deployed a groundbreaking new platform to advance science and technology that addresses wildland fire challenges in an era of more frequent and devastating megafires.

Scuba Diving Generates Up to $20 Billion Annually

An international study estimates that scuba diving contributes between $8.5 and $20.4 billion to the global economy each year, supporting up to 124,000 jobs across 170 countries, offering an economic incentive for marine conservation.

Stealth Genetic Switch in Mosquitoes Halts Malaria Spread

Researchers have developed a system that blocks malaria transmission in mosquitoes, which continue to be the deadliest animals on Earth. The CRISPR-based gene-editing system changes a single molecule within mosquitoes, a tiny but effective change that stops the malaria-parasite transmission process.

Don’t Feed the Animals: Researchers Warn of Risks Tied to Wildlife Interactions

A study led by a UC San Diego scientist offers new warnings on the dangers of human interactions with wildlife. The new report, which focuses on elephants, indicates that human feeding of wild animals can lead to a range of problems and even result in the deaths of humans and animals.

Voracious Honey Bees Threaten the Food Supply of Native Pollinators

A study led by UC San Diego biologists is calling attention to the availability of food for bees in the Southwestern U.S. Non-native honey bees, the study found, extract an overwhelming majority of pollen from regional flowers, posing a significant ecological threat to native bee species.

Diver-Operated Microscope Brings Hidden Coral Biology into Focus

The intricate, hidden processes that sustain coral life are being revealed through a new microscope developed by scientists at UC San Diego’s Scripps Institution of Oceanography. The NSF-funded microscope will help scientists uncover precisely why corals bleach, informing remediation efforts.
