When the English author Sir Francis Bacon wrote "The world's a bubble" in 1629, it's a safe bet he wasn't thinking about microfluidics.
University of Southern Denmark It is a big dream in science: To start from scratch with simple artificial microscopic building blocks and end up with something much more complex: living systems, novel computers or every-day materials. For decades scientists have pursued the dream of creating artificial building blocks that can self-assemble in large numbers and reassemble to take on new tasks or to remedy defects. Now researchers from University of Southern Denmark have taken a step...
Marine cyanobacteria — tiny ocean plants that produce oxygen and make organic carbon using sunlight and CO2 — are primary engines of Earth's biogeochemical and nutrient cycles.
Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have discovered the decisive biological stimulator for the accumulation of defensive substances in leaf beetle larvae used by the insects to fend off predators: ABC transport proteins, which are found in large quantities in glandular cells of the larvae.
The membranes surrounding and inside cells are involved in every aspect of biological function.
Molecular microbiologists at the University of Southern California (USC) have uncovered intricate regulatory mechanisms within the cell that could lead to novel therapeutics for the treatment of cancer and other diseases.

Using the same devious mechanism that enables some bacteria to shrug off powerful antibiotics, scientists have developed solar-powered nanofilters that remove antibiotics from the water in lakes and rivers twice as efficiently as the best existing technology.
Cells ingest proteins and engulf bacteria by a gymnastic, shape-shifting process called endocytosis.
Using bioluminescent proteins from a jellyfish, a team of scientists has lit up the inside of a neuron, capturing spectacular video footage that shows the movement of proteins throughout the cell.
Phallusia nigra is a species of sea squirt (tunicate) found in tropical seas around the world. It is usually found in shallow waters attached to any hard substrate. It is a solitary animal rather than living in colonies. Although the native range of this animal is unknown, the tropical western Atlantic Ocean, the Red Sea and the Indian Ocean are possibilities. Like all ascidians, this species has a thick leathery envelope (tunic) containing cellulosic material. The tunic encloses a...
- In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
