Primitive Artificial Cells Turned Into Complex Biological Materials
2014-02-04 15:22:51

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...

Scientists discover extracellular vesicles produced by ocean microbes 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. They nourish other organisms through the provision of oxygen and with their own body mass, which forms the base of the ocean food chain. Now scientists at MIT have discovered another dimension of the outsized role played by these tiny...

Intracellular ABC Transporters Allow Leaf Beetle Larvae To Accumulate Defensive Substances When Feeding
2013-12-09 11:58:38

Max Planck Institute for Chemical Ecology Similar membrane proteins play a crucial role in the transport of toxic substances out of the cell 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 poplar leaf...

The membranes surrounding and inside cells are involved in every aspect of biological function. They separate the cell’s various metabolic functions, compartmentalize the genetic material, and drive evolution by separating a cell’s biochemical activities. They are also the largest and most complex structures that cells synthesize. Understanding the myriad biochemical roles of membranes requires the ability to prepare synthetic versions of these complex multi-layered structures, which...

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. Their findings, which have long-standing significance in the basic understanding of cell biology, appear in the journal Nature Cell Biology. "Our research reveals a new regulatory mechanism that coordinates two distinct intracellular processes that are critical to...

Female Squid Have Two Ways To Switch Color According To Study
2013-09-19 11:30:34

University of California - Santa Barbara The female common market squid –– AKA Doryteuthis opalescens –– may not be so common after all. Researchers at UC Santa Barbara have discovered that this glamorous cephalopod possesses a pair of stripes that can sparkle with rainbow iridescence. These flank a single stripe, which can go from complete transparency to bright white. This marks the first time that switchable white cells based on reflectins –– the proteins responsible for...

Contaminated Water Cleaned By Solar-powered Nanofilters That Pump In Antibiotics
2013-06-06 20:24:09

American Chemical Society 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. Their report appears in ACS´ journal NanoLetters. David Wendell and Vikram Kapoor explain that antibiotics from toilets and other sources find their way into lakes and rivers, with traces appearing in...

NIH-funded study reveals protein, fatty molecules and cellular energy work together during endocytosis Cells ingest proteins and engulf bacteria by a gymnastic, shape-shifting process called endocytosis. Researchers at the National Institutes of Health revealed how a key protein, dynamin, drives the action. Endocytosis lets cells absorb nutrients, import growth factors, prevent infections and accomplish many other vital tasks. Yet, despite decades of research, scientists don't fully...

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. The video offers a rare peek at how proteins, the brain's building blocks, are directed through neurons to renew its structure. It can be viewed online here: http://www.youtube.com/watch?v=baI9q2--q7s&feature=youtu.be "Your brain is being disassembled and reassembled every day," said Don...

3D movie at ℠ultraresolution´ shows how cell´s machinery bends membrane inwards Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have combined the power of two kinds of microscope to produce a 3-dimensional movie of how cells ℠swallow´ nutrients and other molecules by engulfing them. The study, published today in Cell, is the first to follow changes in the shape of the cell´s membrane and track proteins thought to...

Phallusia nigra
2014-01-12 00:00:00

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...
