Professor Says Earth Is Forming Saturn-Like Rings Made of Space Junk
Wretched Garbage Planet We've got a huge space junk problem — and it's only going to get worse as more and more companies and governments launch satellites, spacecraft, probes, and even tourists into space. While much of what we send to orbit ends up getting sucked back into the Earth's atmosphere to burn up, much of it remains — until we figure out how to do something about it. Things could get

Microbes can provide sustainable hydrocarbons for the petrochemical industry
The petrochemical industry turns oil and gas into precursors used to synthesize lubricants and other critical products. Chemists show that bacteria can be metabolically engineered to generate similar precursors, providing a sustainable replacement for fossil fuels and using less energy. The microbes need only glucose. The medium-chain hydrocarbons they produce can be broken down into shorter chain

The molecular composition of KATP includes an inward-rectifier potassium channel (Kir) and an ABC transporter–like sulfonylurea receptor (SUR). Although structures of KATP have been determined in many conformations, in all cases, the pore in Kir is closed….

Amyloid {beta} 42 fibril structure based on small-angle scattering [Biological Sciences]
Amyloid fibrils are associated with a number of neurodegenerative diseases, including fibrils of amyloid β42 peptide (Aβ42) in Alzheimer's disease. These fibrils are a source of toxicity to neuronal cells through surface-catalyzed generation of toxic oligomers. Detailed knowledge of the fibril structure may thus facilitate therapeutic development. We use small-angle…
