Newly Discovered Ring-Moat Dome Structures in the Lunar Maria: Possible Origins and Implications

Latitudinal variation in spectral properties of the lunar maria and implications for space weathering

Space weathering alters the optical properties of exposed surfaces over time, complicating the interpretation of spectroscopic observations of airless bodies like asteroids, Mercury, and the Moon. Solar wind and micrometeoroids are likely the dominant agents of space weathering, but their relative contributions are not yet well understood. Based primarily on Clementine mosaics, we report a prev...

Implications for the origins of pure anorthosites found in the feldspathic lunar meteorites, Dhofar 489 group

Remote observation by the reflectance spectrometers onboard the Japanese lunar explorer Kaguya (SELENE) showed the purest anorthosite (PAN) spots (>98% plagioclase) at some large craters. Mineralogical and petrologic investigations on the feldspathic lunar meteorites, Dhofar 489 and Dhofar 911, revealed the presence of several pure anorthosite clasts. A comparison with Apollo nearside samples o...

Newly discovered antiterminator RNAs in bacteriophage.

Antiterminator RNA directly modifies the transcription elongation complex so that it terminates less efficiently at intrinsic and factor-dependent terminators. These unusual RNAs were first discovered in bacteriophage HK022, where the nascent transcripts of the phage put sites promote full expression of phage genes during lytic infection. The activity of antiterminator RNA depends on specific s...
