Differences in geographic origin of a person’s mitochondrial and nuclear genomes due to admixture can affect function of mitochondria, energy-generating organelles located inside cells that have their own separate genome. A new study reveals that mitochondrial DNA (mtDNA) copy number decreases with increasing “mito-nuclear” dissimilarity in geographic origins of the mitochondrial and nuclear genomes (e.g. as the proportion of nuclear DNA from population 1 decrease).

Differences in genes’ geographic origin influence mitochondrial function

Differences in the geographic origin of genes may affect the function of human mitochondria — energy-generating organelles inside of cells — according to a new study. Mitochondria have their own genome, separate from the nuclear genome contained in the nucleus of the cell, and both genomes harbor genes integral to energy production by mitochondria. The study explores whether these “mito-nuclear” interactions, which are fine-tuned by natural selection over deep evolutionary time, could be altered when genes of different geographic origins are brought together within a genome.

Cellular protein a target for Zika control

A cellular protein that interacts with invading viruses appears to help enable the infection process of the Zika virus, according to an international team of researchers who suggest this protein could be a key target in developing new therapies to prevent or treat Zika virus infection.

Micropores let oxygen and nutrients inside biofabricated tissues

Micropores in fabricated tissues such as bone and cartilage allow nutrient and oxygen diffusion into the core, and this novel approach may eventually allow lab-grown tissue to contain blood vessels, according to a team of Penn State researchers.

Better security achieved with randomly generating biological encryption keys

Data breaches, hacked systems and hostage malware are frequently topics of evening news casts — including stories of department store, hospital, government and bank data leaking into unsavory hands — but now a team of engineers has an encryption key approach that is unclonable and not reverse-engineerable, protecting information even as computers become faster and nimbler.

Bacterial protein could help find materials for your next smartphone

A newly discovered protein could help detect, target and collect from the environment the rare-earth metals used in smartphones. Two new studies by researchers at Penn State describe the protein, which is 100 million times better at binding to lanthanides — the rare-earth metals used in smartphones and other technologies — than to other metals like calcium.
