Quantum machine shows promise for biological research

To date, much has been stated about the promise of quantum computing for myriad of applications but there have been few examples of a quantum advantage for real-world problems of practical interest. This might change with ...

Ties that bind, and can be untied

LMU researchers have developed a method that enables cell-surface receptors to be switched on and off at will. The technique promises to provide new insights into receptor functions and their effects on intracellular signaling ...

More complex biological systems evolve more freely

Our genes (aka. the genotype) determine our characteristics (aka. the phenotype). Evolution acts on changes in the phenotype, which occur when mutations change the underlying genotype. But what changes to the phenotype can ...

Discovery lights path for Alzheimer's research

A probe invented at Rice University that lights up when it binds to a misfolded amyloid beta peptide—the kind suspected of causing Alzheimer's disease—has identified a specific binding site on the protein that could facilitate ...
