Who will save the night sky?

Who will save the night sky? Vox.com 4/29/2021 Brian Resnick © DELVE Survey, CTIO/AURA/NSF Starlink satellites create bright lines through an observatory’s view of the night sky. If you travel to one of the darkest places on Earth, you can see one of the last great things completely unaltered by humans: the entire night sky. But increasingly, even in the darkest places on Earth (which are vanishingly rare themselves), humankind is beginning to interfere with this primordial view. The unimpeded view of the night sky is being lost, and quickly. In their quest to provide global broadband internet access to remote places, satellite companies are launching small constellation satellites into orbit close to the Earth so that the internet connection doesn’t have too long of a delay.

Scientists Closer to Creating Psychedelic-Like Drugs That Work Without Hallucinations

Their early research, so far only conducted in mice, might someday provide people with more first-line treatments for illnesses like depression. Psychedelics are currently being looked at as possible treatments for mental illness. There are now ongoing clinical trials of drugs like LSD and psilocybin (the main ingredient in hallucinogenic mushrooms) for conditions including depression, anxiety, and post-traumatic stress disorder, sometimes in combination with psychotherapy. Just this month, a new study found that psilocybin plus therapy appeared to be as effective as antidepressants in treating moderate to severe depression.

When Parking Is Punitive

As we round the corner of the pandemic, cities are experiencing optimistic signs of growth with higher revenue projections than previously estimated for 2021. However, when cities contemplate their economic tools to boost revenue, a tool that has particularly regressive consequences is the increased issuance of parking tickets to balance budgets. In driver-centric cities, parking fines can make up a significant proportion, if not the majority, of total fine revenues. In 2015, the City of Los Angeles raised $152 million from parking fees which represented 64% of the city’s total fines, penalties, and fees. Surges in ticket writing prompt residents to see parking enforcement as a means of revenue generation, not traffic or safety management.
