International experts weigh-in on harmful algal blooms
Cambridge, Md. - An international group of scientists is linking nutrient pollution in the world's coastal seas to an increase in the number of harmful algal blooms reported in recent years. When harmful algal blooms (HAB's) occur, they taint seafood with toxins, cause human respiratory and skin irritations and cause fish or mammal kills in coastal waters.

Automated plant growing
The Cheap Vegetable Gardener sent us his fully automated grow chamber project. In the quest to have fresh strawberries year round, they’ve made some progress in the area of automating their plant care. The whole thing is controlled by a computer that can turn on/off the lights and adjust the temperature. It also takes snapshots and logs the environment conditions so you can chart it all out nicely. The automated watering feature isn’t done yet, but hopefully will be soon.

Astronomers use gamma-ray burst to probe star formation in the early universe
(PhysOrg.com) -- The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a GRB host galaxy. By analyzing the spectrum of light emitted in the GRB afterglow, the researchers are gleaning insights into an active stellar nursery in a galaxy so far away it appears as it was 10 billion years ago.

Researchers construct a device that mimics one of nature's key transport machines
(PhysOrg.com) -- To help protect its genes, a cell is highly selective about what it allows to move in and out of its nucleus. Yet that choosiness is regulated by just a thin barrier, perforated with tiny transport machines called nuclear pore complexes: protein-coated holes surrounded by flimsy, unfolded protein strands. Now, by building an artificial mimic of this membrane barrier and its pores, scientists have discovered a key to its selectivity and, in the process, have found a practical tool for drug development.
