"Perfection Is Not A Useful Concept"
Bostrom: We have to distinguish between positional and non-positional goods. In economics, a positional good benefits you only because others lack it. Height may be an advantage in men, but if everybody were three inches taller, nobody would be better off. Attractiveness may be another example of a positional good. A gain for one person implies a relative loss for others. I would contrast that with a trait like health. Your life is better when you are healthy, even if others are also healthy. Cognitive enhancements are a complex topic, but they have aspects that are intrinsically valuable. It is good if we can understand the world better. Arguments against positional goods are no arguments against enhancements as such.

Humans Could Have Geomagnetic Sight
Tests of cryptochrome 2, a key protein component of geomagnetic perception, found that its human version restored geomagnetic orientation in cryptochrome-deficient fruit flies.

Lab-grown meat would 'cut emissions and save energy'
‘What our study found was that the environmental impacts of cultured meat could be substantially lower than those of meat produced in the conventional way,’ said Hanna Tuomisto of Oxford University’s Wildlife Conservation Research Unit, who led the research. ‘Cultured meat could potentially be produced with up to 96% lower greenhouse gas emissions, 45% less energy, 99% lower land use, and 96% lower water use than conventional meat.’
