Electricity-conducting bacteria yield secret to tiny batteries, big medical advances

These strange bacteria conduct electricity via a structure never before seen in nature -- a structure scientists can co-opt to miniaturize electronics, create powerful-yet-tiny batteries, build pacemakers without wires and develop a host of other medical advances.

Novel Hawaiian communities operate similarly to native ecosystems

On the Hawaiian island of Oahu, it is possible to stand in a lush tropical forest that doesn't contain a single native plant. The birds that once dispersed native seeds are almost entirely gone too, leaving a brand-new ecological community composed of introduced plants and birds. In a first-of-its-kind study, researchers demonstrate that these novel communities are organized in much the same way as native communities worldwide.

Poverty leaves a mark on our genes

In this study, researchers found evidence that poverty can become embedded across wide swaths of the genome. They discovered that lower socioeconomic status is associated with levels of DNA methylation (DNAm) -- a key epigenetic mark that has the potential to shape gene expression -- at more than 2,500 sites, across more than 1,500 genes.

Magnetic nanoparticles can 'burn' cancer cells

Unfortunately, cancer isn't simply a single disease, and some types, like pancreas, brain or liver tumours, are still difficult to treat with chemotherapy, radiation therapy or surgery, leading to low survival rates for patients. Thankfully, new therapies are emerging, like therapeutic hyperthermia, which heats tumours by firing nanoparticles into tumour cells. In a new study published in EPJ B, Angl Apostolova from the University of Architecture, Civil Engineering and Geodesy in Sofia, Bulgaria and colleagues show that tumour cells' specific absorption rate of destructive heat depends on the diameter of the nanoparticles and the composition of the magnetic material used to deliver the heat to the tumour.

Ancient, four-legged whale with otter-like features found along the coast of Peru

Cetaceans, the group including whales and dolphins, originated in south Asia more than 50 million years ago from a small, four-legged, hoofed ancestor. Now, researchers reporting the discovery of an ancient four-legged whale -- found in 42.6-million-year-old marine sediments along the coast of Peru -- have new insight into whales' evolution and their dispersal to other parts of the world.

Associating colors with vowels? Almost all of us do!

Does [a:] as in 'baa' sound more green or more red? And is [i:] as in 'beet' light or dark in color? Even though we perceive speech and color are perceived with different sensory organs, nearly everyone has an idea about what colors and vowels fit with each other. And a large number of us have a particular system for doing so.
