Jellyfish's stinging cells hold clues to biodiversity

The cnidocytes -- or stinging cells -- that are characteristic of sea anemones, hydrae, corals and jellyfish, and make us careful of our feet while wading in the ocean, are also an excellent model for understanding the emergence of new cell types, according to new research.

A first: Scientists grow plants in soil from the Moon

Scientists have, for the first time, grown plants in soil from the Moon. They used soil collected during the Apollo 11, 12 and 17 missions. In their experiment, the researchers wanted to know if plants would grow in lunar soil and, if so, how the plants would respond to the unfamiliar environment, even down to the level of gene expression.

Only 10 vaquita porpoises survive, but species may not be doomed, scientists say

The world's smallest marine mammal -- the critically endangered vaquita porpoise, which lives only in Mexico's Sea of Cortez -- is believed to have only 10 living members, if that, of the species. The vaquita is widely thought to be on the verge of extinction, but a new scientific analysis by a team of biologists concludes the species remains relatively healthy and can survive -- if the illegal use of 'gillnet' fishing ceases promptly.

A new 225-million-year-old reptile from Brazil

A reassessment of Faxinalipterus minimus, a purported Triassic pterosaur from southern Brazil resulted in the description of a new taxon -- researchers present Maehary bonapartei a small reptile that is considered to be the most basal of the evolutionary lineage that gave rise to pterosaurs. The study also demonstrates that Faxinalipterus minimus is not a winged reptile, contrary to what was previously supposed.

New tool to create hearing cells lost in aging

Hearing loss due to aging, noise and certain cancer drugs has been irreversible, because scientists have not been able to reprogram existing cells to develop into the outer and inner ear sensory cells -- essential for hearing -- once they die. But scientists now have discovered a single master gene that programs ear hair cells into either outer or inner ones, overcoming a major hurdle that had prevented the development of these cells to restore hearing.
