| Only 10 vaquita porpoises survive, but species may not be doomed, scientists say Posted: 05 May 2022 11:32 AM PDT 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. |
| Lunar soil has the potential to generate oxygen and fuel Posted: 05 May 2022 08:46 AM PDT Soil on the moon contains active compounds that can convert carbon dioxide into oxygen and fuels, scientists report. They are now exploring whether lunar resources can be used to facilitate human exploration on the moon or beyond. |
| Scientists identify the most extreme heatwaves ever recorded globally Posted: 04 May 2022 11:45 AM PDT A new study has revealed the most intense heatwaves ever across the world -- and remarkably some of these went almost unnoticed decades ago. |
| A new 225-million-year-old reptile from Brazil Posted: 04 May 2022 10:08 AM PDT 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 Posted: 04 May 2022 08:04 AM PDT 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. |
