UCLA scientists test new strategy that could help fight ovarian cancer

Approach borrows from technique of inhibiting protein fibers that cause Alzheimer’s and Parkinson’s diseases

UCLA scientists have developed a promising novel method to treat gynecologic tumors. The approach focuses on a protein called p53, which is commonly mutated in women who have high-grade serous ovarian cancer, the deadliest form of reproductive cancer. In many women with the disease, the cancer is very advanced by the time it is diagnosed and is therefore difficult to treat. (more…)

Origin of Moon’s ‘ocean of storms’ revealed

New analysis, using data from NASA’s GRAIL spacecraft, has determined that the large dark patch on the western edge of the Moon’s near side is not an impact crater after all.

PROVIDENCE, R.I. [Brown University] — Oceanus Procellarum, a vast dark patch visible on the western edge of the Moon’s near side, has long been a source of mystery for planetary scientists. Some have suggested that the “ocean of storms” is part of a giant basin formed by an asteroid impact early in the Moon’s history. But new research published today in Nature deals a pretty big blow to the impact theory. (more…)

Misleading mineral may have led to overestimate of water in moon

Discovery of hydrogen-rich apatite in lunar rocks hinted at more watery past. Think again, says UCLA’s Jeremy Boyce.

The amount of water present in the moon may have been overestimated by scientists studying the mineral apatite, says a team of researchers led by Jeremy Boyce of the UCLA Department of Earth, Planetary and Space Sciences.

Boyce and his colleagues created a computer model to accurately predict how apatite would have crystallized from cooling bodies of lunar magma early in the moon’s history. Their simulations revealed that the unusually hydrogen-rich apatite crystals observed in many lunar rock samples may not have formed within a water-rich environment, as was originally expected.
