Hope for fighting disease known as Ebola of frogs
Despite widespread infection, some frog populations are surviving a deadly disease that is the equivalent of humankind's Ebola virus. The reason -- genetic diversity.

New live-imaging technique reveals cellular repair crew plugging leaky biological barrier
Suppose you live in a brick house and notice cracks in the mortar that let in cold air, rain and insect pests. You might call a brick mason to repair those leaks and to restore the barrier that keeps the great outdoors from getting inside.

Improved RNA data visualization method gets to the bigger picture faster
Like going from a pinhole camera to a Polaroid, a significant mathematical update to the formula for a popular bioinformatics data visualization method will allow researchers to develop snapshots of single-cell gene expression not only several times faster but also at much higher-resolution. This innovation by mathematicians will reduce the rendering time of a million-point single-cell RNA-sequencing (scRNA-seq) data set from over three hours down to just fifteen minutes.

Study examines how compound damaged DNA to understand its connection to cancer
In an effort to understand how colibactin, a compound produced by certain strains of E. coli, may be connected to the development of colorectal cancer, researchers are exploring how the compound damages DNA to produce DNA adducts.

Biocolonizer species are putting the conservation of the granite at Machu Picchu at risk
A research group has used a non-destructive methodology to determine the role of specific algae, lichens, mosses, cyanobacteria, etc. that may be causing exfoliation and delamination, which are degrading the Sacred Rock of Machu Picchu, one of the most important symbols in the Peruvian archaeological city.

How proteins become embedded in a cell membrane
Many proteins with important biological functions are embedded in a biomembrane in the cells of humans and other living organisms. But how do they get in there in the first place? Researchers have now investigated the matter.

Tracking pollen with quantum dots
Most plant species on earth are reliant on insects for pollination, including more than 30% of the food crops we eat. With insects facing rapid global decline, it is crucial that scientists understand which insects are important pollinators of different plants--this starts with tracking pollen.

Diagnostic tool for detecting cryptosporidium
Using a small and inexpensive biosensor, researchers have developed a novel low-cost technique that quickly and accurately detects cryptosporidium contamination in water samples.

More scrutiny needed for less-deadly foodborne bacteria
Employing advanced genetic-tracing techniques and sharing the data produced in real time could limit the spread of bacteria -- Bacillus cereus -- which cause foodborne illness, according to researchers who implemented whole-genome sequencing of a pathogen-outbreak investigation.
