Just as scientists are starting to understand the life forms and landscape of the ocean, they are also coming to grips with the threat of mass extinctions, speakers said at a marine biodiversity forum last week.

Tree of life brought to scale by Yale scientists

Examples of biological scaling are everywhere. The paw of a mouse is smaller than the human hand. Our own organs and limbs typically scale with our body size as we develop and grow.

Bacteria reveal strong individuality when navigating a maze

Researchers from ETH Zurich demonstrate that genetically identical cells exhibit differing responses in their motility towards chemical attractants. Average values hide the full picture when it comes to describing the behavior ...

Forest fires as an opportunity for ecosystem recovery

Large forest fires occur with increasing frequency globally, and their consequences grow more severe and destructive. Climate change and human activity are influencing the capacity of ecosystems and the life forms that inhabit ...

Enzyme warps space to break the cell's speed limit

Johns Hopkins researchers have found that rhomboid enzymes, which are special proteins that cut other proteins, are able to break the "cellular speed limit" as they move through the cell membrane. Rhomboid enzymes do this ...

Environmental protection in outer space

Should regulations for environmental protection be valid beyond our solar system? Currently, extra-terrestrial forms of life are only deemed worth protecting if they can be scientifically investigated. But what about the ...

A boost for photosynthesis

Photosynthesis is a fundamental biological process by which plants use light energy for growth. Most life forms on Earth are directly or indirectly dependent on photosynthesis. Researchers at the Max Planck Institute of Biochemistry ...
