Copper nanoparticles can catalyze the formation of methanol from a mixture of CO2, CO, and H2, but adding zinc oxide nanoparticles, themselves inactive in this – [Read More]
20 May
What are the mechanisms that create different, highly specific types of synapses? Traunmüller et al. found that the RNA-binding protein SLM2 regulated a very small number – [Read More]
20 May
Despite the success of antiretroviral therapy, HIV-1-infected individuals still harbor latent virus. Thus, other therapeutic strategies are needed. A single injection of a broad and – [Read More]
20 May
Osteoblasts are bone-building cells that secrete a collagen-rich matrix required for bone formation. Defects in collagen deposition cause the brittle bones that are characteristic of – [Read More]
20 May
Artificial spin ices are arrays of nanoscale bar magnets that can mimic the behavior of naturally occurring “frustrated” magnetic materials. Usually the arrays take the form of a s – [Read More]
20 May
Aerial views offer the chance to observe a wide range of terrain at once, but they come at the cost of needing to stay aloft. Graule et al. found that electrostatic forces – [Read More]
20 May
The alarmone guanosine-3′,5′-(bis)pyrophosphate (ppGpp) shuts down transcription in bacteria that are starving. This “stringent response” helps them conserve energy and survive adverse – [Read More]
20 May
Coordination between actin and microtubule cytoskeleton dynamics is critical during cell migration, phagocytosis, cytokinesis, and embryogenesis. However, the basis for cross-regulation – [Read More]
20 May
Patients undergoing allogeneic hematopoietic stem cell transplantation often receive antibiotics for infections, which unfortunately also kill intestinal bacteria. These symbiotic bacteria – [Read More]
20 May
Therapies targeting the tumor microenvironment show promise for treating cancer. For example, antibodies targeting colony-stimulating factor-1 receptor (CSF-1R) inhibit protumorigenic – [Read More]
20 May
The phase diagram of any given family of iron-based superconductors is complicated: Superconductivity competes with antiferromagnetism, with a structural transition often thrown in – [Read More]
20 May
In superconductors, the electrical current is carried by “Cooper pairs,” formed out of an electron and a hole. This supercurrent will happily cross a thin barrier between two superconductors. But – [Read More]
20 May
Cellular phosphate (Pi) levels are tightly controlled, but it is not clear how eukaryotic cells actually “measure” the concentration of Pi. Wild et al. now show that inositol pol – [Read More]
20 May
Many receptor proteins that respond to biological signals form multimeric complexes, which gives them more sophisticated regulatory properties than those of simple one-to-one binding – [Read More]
20 May
Understanding genetic redundancy—the maintenance of multiple copies of a gene after duplication—and its relevance to genetic evolution have long been debated. Lan and Pritchard exa – [Read More]
20 May
In biological systems, membrane proteins regulate flow into and out of cells and play key roles in cell signaling and shaping cell morphology. Scientists are now using DNA to create – [Read More]
20 May
Microorganisms are the main drivers of Earth's methane cycle. The enzyme ultimately responsible for biological methane production has an ambiguous mechanism because it involves difficult-to-isolate – [Read More]
20 May
One approach for increasing the activity of precious metals in catalysis is to coat them onto less expensive earth-abundant transition metal cores such as nickel, but often these structures – [Read More]
