چکیده
Extremely low background experiments to measure key nuclear reaction cross sections of astrophysical interest are conducted at the world's deepest underground laboratory, Jingping Underground laboratory for Nuclear Astrophysics (JUNA). High precision measurements provide reliable information understand nucleosynthetic processes in celestial objects and resolve mysteries on origin atomic nuclei discovered first generations Pop.

Shedding light on an underground problem.
I this issue of PNAS, Nishimura et al. demonstrate that ASTRAY, the legume homolog of HY5, a transcription factor that mediates light signaling and photomorphogenesis above ground, also affects the interaction between legume roots and their rhizobial endosymbionts underground (1). At first glance, this is a confusing result. What is a transcription factor that mediates light signaling doing reg...
متن کاملEvolution underground: shedding light on the diversification of subterranean insects
A recent study in BMC Evolutionary Biology has reconstructed the molecular phylogeny of a large Mediterranean cave-dwelling beetle clade, revealing an ancient origin and strong geographic structuring. It seems likely that diversification of this clade in the Oligocene was seeded by an ancestor already adapted to subterranean life.
متن کاملShedding Light on Light*
There are four books describing early studies and views on light, optics and vision that are considered to be landmarks in this branch of science. The first of these is Euclid’s Optica, published about 300BC, in which he postulated that light travelled in straight lines; he described the laws of reflection and described them mathematically. The second is by Ptolemy. He is best known for his 15 ...
متن کاملNucleosynthesis in stellar flares
Nuclear interactions of ions accelerated at the surface of flaring stars can produce fresh isotopes in stellar atmospheres. Although this nucleosynthesis is not significant for the chemical evolution of the Galaxy, it can be important for a number of measurements of “anomalously” high Li and Li abundances. We discuss the possible role of stellar flares to explain the recent report of high Li ab...
متن کاملShedding light on NSOM.
I took patience and hard work. Now, finally, researchers are seeing some sunshine break through what was once a cloudy beginning for near-field scanning optical microscopy (NSOM). Paul Barbara of the University of Texas–Austin (UT– Austin) is among a group of analytical chemists who have a deep respect for this tool and see it as a technique ripe with potential, ranging from chemistry to physic...
