When organisms pass their genes on to future generations, they include more than the code spelled out in DNA.

The Kidney Project Successfully Tests a Prototype Bioartificial Kidney
The Kidney Project’s implantable bioartificial kidney, one that promises to free kidney disease patients from dialysis machines and transplant waiting lists, took another big step toward becoming reality, earning a $650,000 prize from KidneyX for its first-ever demonstration of a functional prototype of its implantable artificial kidney.
Resistant E. coli rises despite drop in ciprofloxacin use
After a nearly threefold drop in prescriptions for the antibiotic ciprofloxacin between 2015 and 2021, the rates of ciprofloxacin-resistant E. coli bacteria circulating in the community did not decline. In fact, a study of Seattle-area women over age 50 who had not taken any antibiotics for at least a year discovered that...
Saving species from extinction — high-quality kakapo population sequencing provides breakthrough in understanding key conservation genetics
High-quality sequencing of nearly the entire kakapo population is helping New Zealand to manage the health of this critically endangered species.
Curious and cryptic: New leaf insects discovered
An international research team has described seven previously unknown species of leaf insects, also known as walking leaves. The insects belong to the stick and leaf insect order, which are known for their unusual appearance: they look confusingly similar to parts of plants such as twigs, bark or -- in...
Historic red tide event of 2020 fueled by plankton super swimmers
A major red tide event occurred in waters off Southern California in the spring of 2020, resulting in dazzling displays of bioluminescence along the coast. Now, for the first time, a study has pinpointed how the plankton species Lingulodinium polyedra -- a dinoflagellate -- was able to create such an...
Wastewater pipe dig reveals ‘fossil treasure trove’
A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark...
Researcher finds inspiration from spider webs and beetles to harvest fresh water from thin air
A team of researchers is designing novel systems to capture water vapor in the air and turn it into liquid. They have developed sponges or membranes with a large surface area that continually capture moisture from their surrounding environment.
Scientists invent new way to sort cells by type using light
Researchers have developed and demonstrated a new method for high-throughput single-cell sorting that uses stimulated Raman spectroscopy rather than the traditional approach of fluorescence-activated cell sorting. The new approach could offer a label-free, nondestructive way to sort cells for a variety of applications, including microbiology, cancer detection and cell therapy.
Tiny magnetic beads produce an optical signal that could be used to quickly detect pathogens
Engineers identified an optical signature in a widely used class of magnetic 'Dynabeads' that could be used to quickly detect contaminants in food, water, or the human body.
