How anti-sprawl policies may be harming water quality
Urban growth boundaries are created by governments in an effort to concentrate urban development — buildings, roads and the utilities that support them — within a defined area.

A new study suggests that extremely rare, harmful genetic mutations present in healthy donors' stem cells — though not causing health problems in the donors — may be passed on to cancer patients receiving stem cell transplants, potentially creating health problems for the recipients. Among the concerns are heart damage, graft-versus-host disease and possible new leukemias.

Jumping genes threaten egg cell quality
A woman's supply of eggs is finite, so it is crucial that the quality of their genetic material is ensured. New work from Carnegie's Marla Tharp, Safia Malki, and Alex Bortvin elucidates a mechanism by which, even before birth, the body tries to eliminate egg cells of the poorest quality. Their findings describing this mechanism are published by Nature Communications.

Record levels of renewable energy have driven the first drop in Australia's annual greenhouse gas emissions since 2015 but if maintained the rate of decline would mean the country's Paris pledge would be met 68 years late.

If CEO's and other administrative positions are so expensive and automation cuts costs; at what point in the future will AI (or robots I suppose) start to replace CEOs?
I would imagine someone creates an open source kind of manager-bot or something along those lines like Linux but for administrative duties. I mean proprietary software is potentially possibly as well but who is going to make it? IBM? Oracle? A weird offshoot of Byrd Scooter Technology? My point is, companies could save a lot of money but having an AI run things. And they would never need to worry

Meghan, Kate, and the Architecture of Misogyny
Are you Team Kate or Team Meghan? If you're anything like me, you don't want to pick a side—and you don't think there should be "sides" at all. Yet ever since Meghan Markle married Prince Harry, parts of the media have pitted the former actor against her sister-in-law. Where Kate Middleton was once depicted as a dull social climber, she is now presented as the epitome of female virtue : a respect
