On the origin of B1 cells

A new study may resolve a decades-old debate in immunology: researchers report that distinct progenitor cells are not required for the development of B1 cells. Instead, the team's experiments show that a B1-typical B-cell receptor can reprogram B2 cells into B1 cells, suggesting that B1 cells emerge as a consequence of their special B-cell receptors.

Teens living in US states allowing medical marijuana smoke less cannabis

According to a large-scale study of American high school students, legalizing medicinal marijuana has actually led to a drop in cannabis use among teenagers. The study used the results of an anonymous survey given to more than 800,000 high school students across 45 states to calculate the number of teens who smoke cannabis.

Study on measles transmission in China have implications for controlling the epidemic worldwide

A new study on the measles epidemic in China has far-reaching implications for eliminating the infection globally. Using a new model-inference system, the researchers were able to estimate population susceptibility and demographical characteristics in three key locations in China, in a period that spans the pre-vaccine and modern mass-vaccination eras.

New molecular blueprint advances our understanding of photosynthesis

Researchers have used one of the most advanced microscopes in the world to reveal the structure of a large protein complex crucial to photosynthesis, the process by which plants convert sunlight into cellular energy. The finding will allow scientists to explore for the first time how the complex functions, and could have implications for the production of a variety of bioproducts, including plastic alternatives and biofuels.

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.
