Lakes on Saturn's moon Titan can stratify like those on Earth https://ift.tt/3jgxho6

Lakes on Saturn's moon - Titan - composed of methane, ethane, and nitrogen rather than water, experience density-driven stratification, forming layers similar to lakes on Earth. However, whereas lakes on Earth stratify in response to temperature, Titan's lakes stratify solely due to the strange chemical interactions between its surface liquids and atmosphere, says a paper by Planetary Science Institute Research Scientist Jordan Steckloff. Stratification occurs when different parts of a lake have different densities, with the less dense layer floating atop the denser layer.

Transit Lanes Keep Muni Moving on Mission Street in SoMa

Transit Lanes Keep Muni Moving on Mission Street in SoMa By Erin McMillan The full-time transit lanes on Mission Street downtown installed as a temporary emergency measure during the pandemic will be made permanent. The first of the city’s Temporary Emergency Transit Lanes to get permanent authorization, they were unanimously approved by the SFMTA Board of Directors at their June 15, 2021 meeting. This shows how a quick-build project can be installed, evaluated, and refined in a relatively short amount of time. Thousands of daily riders have already felt the impact of the full-time transit lanes since they were first temporarily installed last summer. Now, riders of the 14 Mission, 14R Mission Rapid, and many SamTrans and Golden Gate Transit customers will continue to benefit from the transit time savings we have seen with the implementation of these lanes. Mission Street in SoMa has been a major transit corridor for years, serving regional commuter...

Residents Overwhelmingly Support Slow Streets

Residents Overwhelmingly Support Slow Streets By Eillie Anzilotti After over a year of Slow Streets providing safe, low-volume corridors for people to walk, bike, play and travel during the pandemic, we’re excited to share our first comprehensive evaluation of the program . The key takeaway? San Franciscans are overwhelmingly in support of Slow Streets. Slow Streets are designed to limit through traffic on certain residential streets and allow them to be used as a shared roadway for people traveling by foot and by bicycle. Since introducing Slow Streets in April 2020 in response to the Mayor’s Emergency Health Order, SFMTA has designated around 30 corridors covering 47 miles of roadway as Slow Streets. The program has evolved from a critical component of San Francisco’s pandemic response and recovery to a potential new avenue to further the city and SFMTA’s goals around climate action and sustainable transportation. As the Slow Streets program has grown, we wanted to make sure we...

The Future of Slow Streets

The Future of Slow Streets By Eillie Anzilotti Over the past two years, Slow Streets have shown how simple designs that prioritize people can transform streets. Suddenly, streets across San Francisco filled with the sounds of kids playing and neighbors chatting. They filled with people on bicycles and people rolling in wheelchairs; with joggers and dog-walkers. The streets came to life. Initially, the SFMTA introduced Slow Streets as an emergency response to COVID-19. People needed space for recreating at a safe distance outdoors. And with Muni service reduced or suspended at the time, people needed ways to travel to essential destinations on foot or bike. To quickly meet these early pandemic needs, we implemented Slow Streets with simple signs and barricades. Over time, it became clear that Slow Streets served an even larger purpose. They became places for communities to come together. Neighbors organized events like scavenger hunts and Trick or Treat parties around their local Sl...

https://ift.tt/3a8KgF0 TWICE delivered a special performance at the TIME100 Talks Friday.

Looking Back at the Roots of Muni Heritage Day

Looking Back at the Roots of Muni Heritage Day By Jeremy Menzies Muni Heritage Day returns this Saturday, June 4 from 10 a.m. to 4 p.m., after a two-year hiatus. This event brings our unique fleet of vintage buses and historic streetcars back on San Francisco streets for free rides. All rides will originate from Steuart Street and Don Chee Way, just outside the SF Railway Museum . In preparation for Saturday’s festivities, we look back at the origins of this event in the 1980s through some newly scanned historic photos. Seen here at the 1983 Trolley Festival, the “Boat Tram” has always been a crowd pleaser. The story of Muni Heritage is intertwined with both that of the F Line and a series of events called “Trolley Festivals”. The inaugural Trolley Festival in 1983 was the first time Muni ran special rail service using a collection of vintage cars from San Francisco and around the world. Today, Muni Heritage carries on this tradition for people to ride vehicles that ar...

Taking Muni to Bike San Francisco’s Iconic Rides By Kate McCarthy Take your bike on Muni using the racks on the front of buses to access bike rides on the Great Highway, through Golden Gate Park and across the Golden Gate Bridge. Thousands of riders are expected to hop on a bike in May for National Bike Month and Bike to Wherever Day on Friday, May 20 . For people new to bicycling in San Francisco, using Muni buses to avoid our famous hills and reduce overall trip distances is a great way to get to iconic bike rides and scenic parks. All Muni buses have bike racks on their front that can hold two or three bikes (only folding bicycles are allowed on Muni’s Metro trains and historic streetcars). Using the bike racks on Muni buses to transport your bike is easy! And, if you have questions while you are doing it, you can always ask the operator, who can assist you. Those looking to bicycle in parks, along the Great Highway, through Golden Gate Park or across the Golden Ga...

New top story from Time: A Photographer’s Journey Through the Dangerous New Age of Conspiracies in America

https://ift.tt/354JVAF In November 2017, the House Intelligence Committee released fake advertisements found on Facebook in the walk up to the 2016 election. As politicians on each side argued over whether the ads changed the election results, the heart of the revelation was way more disturbing. The Russian ads targeted the American public to deepen wounds on divisive issues and spread false information. Facebook said the posts were “ what we saw from these actors was an insidious attempt to drive people apart ,” according to Colin Stretch, the general counsel for the company. In 2020, less than one month before the election, America seems even more divided and deeply fractured after a turbulent year with a deadly pandemic, economic pain, and a chaotic presidency. With many Americans on lockdown, social media has been a vital form of communication — but one that is also driving dangerous conspiracies. From the false QAnon conspiracy, which promotes Trump as the final de...
