Ocean plankton reveal sugar-for-nutrients partnership that sustains life in barren seas‎

In the vast, nutrient-poor regions of the world's oceans, there is a constant struggle for survival. Yet tiny organisms known as Collodaria have thrived there for millions of years. These Collodaria host microscopically small algae that are essential for survival.

First 15 days of egg development may determine survival for California's most endangered salmon‎

Sacramento River winter-run Chinook salmon are California's most endangered salmon, with a single surviving population and an average of a few thousand returning fish in recent decades. Shasta Dam blocks their original habitat in cold mountain rivers draining Mount Shasta, leaving them to spawn in the low-lying Sacramento River, heated by the summer sun.

Autonomous ship operators' liability remains unclear during oil spills‎

If a remotely operated oil tanker causes a spill, the shipowner remains responsible for compensating victims under existing international rules. But another question remains unresolved: Can the person controlling the ship from shore also be sued directly for negligence?

Shipwrecks from WWI and WWII are polluting the North Sea‎

In April 1917, the German submarine UC-30 sailed beneath the waves off the coast of Rømø. It had originally been on a mission in Ireland, but after suffering engine trouble, it turned around and was almost home in Germany.

Patience predicts longer education paths and faster earnings growth, real-money experiment finds‎

Some teenagers are happy to wait for a bigger reward tomorrow rather than cash in today. Others would rather take the sure thing now—or gamble on a risky, high-payoff bet. According to a new study, these everyday differences in patience and risk appetite are more than personality quirks. They help determine which program a high school graduate chooses—and, with it, the shape of their working life for decades to come.

LHC collisions reveal oxygen and neon's shifting nuclear geometry‎

Many people are aware that the Large Hadron Collider (LHC) at CERN smashes tiny subatomic particles together at nearly the speed of light to test foundational laws of physics and discover new fundamental particles, but some experiments also help scientists better visualize the actual structure of atoms we are already familiar with, like oxygen and neon.
