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.

Researchers find that the ants of the acacia tree are tipped off to the presence of herbivores by vibrations that run throughout the trees when an animal gets too close or begins to chew. As a result, the insects begin patrolling the acacia's branches more actively. Remarkably, the researchers show, the ants don't react when the trees' movements are caused only by the wind.

Research has suggested that the efficiency with which we transport oxygen to our tissues (cardiorespiratory fitness) is a far greater predictor of gut microbiota diversity than either body fat percentage or general physical activity.

Astronomers have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at least 4000 stars that have been moving together in space since they formed, about 1 billion years ago.

Hourly water level records collected from tide gauges can be used to measure land uplift caused by episodic tremor and slip of slow earthquakes in the Cascadia Subduction Zone, according to a new report.

In the course of their life, open star clusters continuously lose stars to their surroundings. The resulting swath of tidal tails provides a glimpse into the evolution and dissolution of a star cluster. Thus far only tidal tails of massive globular clusters and dwarf galaxies have been discovered in the Milky Way system. In open clusters, this phenomenon existed only in theory. Researchers have now finally verified the existence of such a tidal tail in the star cluster closest to the Sun, the Hyades. An analysis of measurements from the Gaia satellite led to the discovery.

Setbacks in drug trials aiming to raise HDL have led researchers to reassess the particle's effects on heart health. A study combining proteomics and mouse genetics may help researchers understand researchers understand the proteins in the particle, how they get there and how they determine HDL function.
