Amniotic stem cells can be collected from vaginal fluid rather than more invasive techniques

Researchers at CU Anschutz Medical Campus have found a new source of patient-specific stem cells by collecting amniotic fluid from vaginal fluid after childbirth. This method allows for expanded and readily available access to these stem cells, which can be used to create functional heart tissue for treating congenital heart defects.

Understanding relationship development: Towards a more rigorous approach

A new paper from the University of Illinois discusses how contemporary methodologies can be applied to common relationship theories in a more rigorous way. The study employs Group-Based Trajectory Modeling (GBTM) to test theoretical-driven hypotheses about relationship development, providing insights for couples and helping practitione...

Microalgae-based production of dietary protein using solar-derived formate

A robust Chlamydomonas reinhardtii cultivation system was established using formate as the carbon source, achieving successful algal growth at 200 mM formate concentration. Protein quality assessments demonstrated that algal biomass met premium protein criteria with essential amino acid scores exceeding nutritional requirements.

Relief from drought in southwest U.S. likely isn’t coming, according to new research

A recent study from the University of Texas at Austin finds that climate change may be disrupting the natural Pacific Decadal Oscillation cycle, which brings needed rain to the region. This could lead to prolonged droughts in the southwest U.S., affecting water resources like the Colorado River.

Most of us love memes. But are they a form of comics?

Research by Ohio State University professor Michelle Ann Abate argues that memes are a type of digital comic. Memes use similar visual and verbal elements to comics, producing humor through interplay between text and image. However, differences exist in layout and format, with memes often arranged vertically for online consumption.

Reduction in supply of prey was decisive factor in extinction of saber-toothed tigers, study finds

Researchers at UNICAMP found that a reduction in prey availability was a decisive factor in the extinction of saber-toothed tigers. The study also shows that an increase in predator diversity led to a decline in herbivore species diversity among antilocaprids, which are now represented by a single species: the American bison.

Efforts to eradicate invasive mussels likely to kill off many Idaho animal species

A new study finds that the copper-based molluscicide used to treat invasive mussels in Idaho's Snake River has devastating effects on the local ecosystem. Nearly half of the original mass of copper is gone after just 10 days, but dissolved copper concentrations remain toxic for over two weeks.
