The persistent danger after landscape fires
Every year, an estimated four percent of the world's vegetated land surface burns, leaving more than 250 megatons of carbonized plants behind. A study has now recorded elevated concentrations of environmentally persistent free radicals (EPFR) in these charcoals - in some cases even up to five years after the fire. These EPFR may generate reactive substances, which in turn harm plants and living organisms.

'Climbing droplets' could lead to more efficient water harvesting
Researchers have discovered that a novel surface they developed to harvest water from the air encourages tiny water droplets to move spontaneously into larger droplets. When researchers placed microdroplets of water on their liquid-lubricant surface, the microdroplets propelled themselves to climb, without external force, into larger droplets along an oily, ramp-shaped meniscus that forms from the lubricant around the larger droplets. The 'coarsening droplet phenomenon' formed droplets large enough for harvesting.

Creating a Better Market Street: Car-free Enforcement to Resume
Creating a Better Market Street: Car-free Enforcement to Resume

It’s been over a year since Market Street went “car-free” on January 29, 2020, but shortly afterwards, the COVID-19 pandemic shut down our city and changed how people move through San Francisco. As the city begins to reopen and vehicle traffic is increasing, we are by stepping up compliance and enforcement efforts to keep Market Street car-free starting March 29, with the help of SFMTA’s Parking Control Officers (PCOs) and the San Francisco Police Department (SFPD).
Under the year-old car-free rules established as a part of Better Market Street, no private vehicles are allowed to travel along Market Street eastbound from 10th to Main streets or westbound from Steuart Street to Van Ness Avenue. Traffic is still allowed to cross Market Street, but there are no turns allowed onto the street in the car-free area. These restrictions apply to all private vehicles, including Uber, Lyft, Postmates, DoorDash, and other services whose drivers use personal vehicles without a commercial license plate.
Map: Car-free area on Market Street, implemented January 2020.
Enforcement of compliance will increase starting March 29 and will continue for about a month to help remind drivers of the restrictions. PCOs and police officers will monitor the street at various locations. PCOs will wave on vehicles attempting to turn onto Market Street within the restricted area. During the first week of the campaign the SFPD will issue warnings to drivers as we ramp up education efforts. Thereafter, they will issue citations to vehicles in violation of the car-free restrictions.
These efforts are in direct response to violations and concerns we’re heard from people that private vehicles are still driving in the car-free area. We also understand and appreciate concerns around police enforcement and we’re working hand in hand with SFPD to address those concerns.

Vehicles that are still allowed to use Market Street:
- Muni and other transit service vehicles
- Taxis
- Paratransit
- Licensed commercial vehicles
- Emergency service vehicles
- Bicycles
- Scooters
Don’t get ticketed! If you’re not one of the vehicles above, don’t drive on Market Street east of Van Ness Avenue. Pay close attention to signage like those shown in the photos. If you’re using a navigation app it will route you around the car-free area.
Please help us spread the word to family, friends, neighbors and coworkers. Plan your trips accordingly. Consider alternate modes of travel if you’re going downtown. If you need to use your personal vehicle to reach destinations along Market Street, take alternate streets – they’re open!
Keep checking the COVID-19 Muni Core Service Plan website for the latest Muni service as we continue to expand and restore additional Muni rail routes which will improve transit service along Market Street.

Starting March 22, a new program will provide free access to SamTrans Route 122 within San Francisco between Lake Merced Boulevard and Lake Merced Hill. The SFMTA has teamed up with SamTrans to launch this pilot program, which allows residents to sign up to use the 122 while Muni service is limited due to COVID-19.
After applying to the program, customers will be sent an email with a MuniMobile pass link that will be valid for six months. There will be an opportunity to extend the pass if the program is still needed after that, pending the return of Muni’s 57 Parkmerced.
Map of new SamTrans stops in the Lake Merced neighborhood
The SFMTA will post signs at the new bus stop locations and at essential destinations including grocery stores near Stonestown Galleria Shopping Center in order to inform community members about this free pilot program. For more information and to apply, visit the Samtrans Route 122 application page.
