Marine biology
Marine biology is the scientific study of the plants, animals, and other organisms that live in the ocean. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.

Nov. 24, 2025 Sargassum seaweed is creating major new obstacles for sea turtle hatchlings, drastically slowing their crawl to the ocean and increasing their risk from predators and heat. Despite the physical challenge, their energy stores stay stable, suggesting ...
Nov. 24, 2025 UC Davis researchers engineered wheat that encourages soil bacteria to convert atmospheric nitrogen into plant-usable fertilizer. By boosting a natural compound in the plant, the wheat triggers bacteria to form biofilms that enable nitrogen ...
Nov. 23, 2025 Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at different points, researchers can now watch damage ...
Nov. 22, 2025 Migratory birds that fill North American forests with spring songs depend on Central America’s Five Great Forests far more than most people realize. New research shows these tropical strongholds shelter enormous shares of species like Wood ...
Nov. 21, 2025 Scientists used CRISPR to boost the efficiency and digestibility of a fungus already known for its meatlike qualities. The modified strain grows protein far more quickly and with much less sugar while producing substantially fewer emissions. It also ...
Nov. 20, 2025 Scientists confirmed that West Coast transient killer whales actually form two separate groups split between inner and outer coastal habitats. Inner-coast whales hunt smaller prey in shallow, maze-like waterways, while outer-coast orcas pursue large ...
Nov. 20, 2025 Researchers have recreated a miniature human bone marrow system that mirrors the real structure found inside our bones. The model includes the full mix of cells and signals needed for blood production and even maintains this process for weeks. It ...
Nov. 19, 2025 Massive Sargassum blooms sweeping across the Caribbean and Atlantic are fueled by a powerful nutrient partnership: phosphorus pulled to the surface by equatorial upwelling and nitrogen supplied by cyanobacteria living directly on the drifting algae. ...
Nov. 18, 2025 During years of scarce fish, African penguins crowd into the same areas as commercial fishing vessels, heightening competition for dwindling prey. A new metric called “overlap intensity” shows how many penguins are affected and is already ...
Nov. 18, 2025 Scientists are turning venom, radioisotopes, engineered proteins, and AI into powerful new tools against cancer. From Amazonian scorpions yielding molecules that kill breast cancer cells as effectively as chemotherapy, to improved fibrin sealants ...
Nov. 17, 2025 Scientists mapped the Bas63 bacteriophage in unprecedented detail, uncovering how its tail machinery infects bacteria. The structure reveals rare whisker-collar features and distant evolutionary ties reaching back billions of years. These insights ...
Nov. 17, 2025 Across the planet, animals are increasingly suffering from chronic illnesses once seen only in humans. Cats, dogs, cows, and even marine life are facing rising rates of cancer, diabetes, arthritis, and obesity — diseases tied to the same factors ...
