Scientists mine the rich seam of body wearable motion sensors
Body movement can be identified through clothing by passing a low voltage through a seam sewn from conductive yarn. Seam-based fitness trackers hold promise for tracking subtle movements (yoga, Pilates, rehabilitation, etc) -- something today's fitness watches struggle with. Stretching conductive seams reduces voltage, and the increase in resistance broadly indicates the level of stretch. Changes in voltage are recorded using a microcontroller.

Parasites manipulate praying mantis's polarized-light perception, causing it to jump into water
Researchers have revealed that praying mantis (mantids) infected with parasitic hairworms are attracted to horizontally polarized light that is strongly reflected off the surface of water, which causes them to enter the water. These results demonstrate that parasites can manipulate the host's specific light perception system to their advantage, causing the host to behave in an abnormal manner.

Powered Scooters Charge City’s Transportation Recovery

Powered Scooters Charge City’s Transportation Recovery
Powered Scooters Charge City’s Transportation Recovery

The SFMTA is releasing its next round of Powered Scooter Share permits on July 1.

Scooters remain a sustainable mode of travel and a complement to Muni and public transit service as the city recovers from the pandemic and San Franciscans begin to travel more. The SFMTA’s Powered Scooter Share Program is essential in ensuring that shared scooter operations support the city’s economic recovery in a safe, sustainable, and equitable way. 

The SFMTA received four submittals for the permit program and will issue permits to two operators: Spin and Lime. Permits will be in effect for a one-year term, with the option to extend for another year at the discretion of the SFMTA based on compliance with various program metrics.

While the new permit program does not set a limit on the number of scooters each operator may deploy, it does limit the overall citywide fleet size at 10,000. Starting at a base of 2,000 scooters per operator, permittees will be encouraged to apply for permission add scooters in 500 increments every several months. Fleet size increases will be predicated on compliance with SFMTA defined metrics and policy outcomes, including those focused on equity, access, and sustainability.

Allowable Scooter Fleet Size at Permit Launch

Lime      2,000

Spin       2,000

The SFMTA also received an application for the 2021 Powered Scooter Share Permit Program from Scoot. The Agency recently learned of revelations, confirmed by Scoot, that the company has been using unauthorized subcontractors in violation of the terms and conditions of the 2019 permit program. The SFMTA takes these issues very seriously, and will defer a decision on 2021 permit issuance to Scoot to allow time for full investigation and complete its evaluation. Scoot service will pause on July 1st during this time.  

New Permit Highlights

The 2021 Powered Scooter Share Permit program builds on the lessons learned from current permit program with the goal of creating a more useful, safe, and equitable program. It establishes new guidance and requirements in these areas:

Accessibility

Adaptive scooters will become a permanent part of the citywide scooter fleet. Additionally, operators will continue their on-demand adaptive programs.

Community Engagement

Permits include new outreach requirements and programs with Community-Based Organizations and local small businesses to expand to a more diverse and equitable ridership.

Labor Harmony

The new permit applications prioritized operators who more frequently hire employees rather than use outside staffing agencies or independent contractors.

Safety

Permittees must implement an escalating penalty structure for unsafe or illegal riding or parking behavior. Furthermore, safety-related scooter charging requirements have been strengthened per feedback from the San Francisco Fire Department.

Equitable Access to Scooters and Distribution Requirements

The program emphasizes service to all neighborhoods in San Francisco. This includes ensuring that everyone in the city is within walking distance of a scooter, particularly in Communities of Concern and outlying areas.

Scooter Parking

The SFMTA will increase the bike rack fee paid by operators from $75 to $100 per scooter to ensure adequate scooter parking throughout the city.

Next Steps – Permitting

The Agency plans to closely monitor permittees’ compliance with the permit terms and conditions once the new permits launch on July 1st. The Agency also looks forward to further stakeholder collaboration as it continues to evolve the Powered Scooter Share Program.

Extended Service Hours for the F Market & Wharves

Beginning June 26, the hours of operation for F Market & Wharves historic streetcars will be extended daily to run from 7 a.m. to 10 p.m. in order to support San Francisco’s economic recovery and reopening.

Trips from Castro to Fisherman’s Wharf will run approximately from 7 a.m. to 9 p.m. and return trips from Fisherman’s Wharf will run approximately 8 a.m. to 10 p.m.

This increase in service is based on feedback from streetcar operators and key stakeholders who worked closely with the SFMTA earlier this year to determine initial hours of operation that would support small businesses along Market Street and the Embarcadero.

Last May, the F Wharves-Market was welcomed back by Mayor London Breed, the San Francisco Board of Supervisors and the SFMTA Board of Directors at a small celebration near the Ferry Building. Director Tumlin was in attendance to make the announcement about the return of historical streetcars and other May 15 service changes, including the reopening of Muni Metro stations.

While Better Market Street construction is still under review, the project team has been developing a plan to run the F Market & Wharves full route. A combination of historic streetcar and bus shuttle service would limit impacts once construction begins.  

San Francisco lifted most COVID-19 restrictions on June 15 and SFMTA staff will continue to support our economic recovery as businesses reopen, tourists, office workers and regional visitors return. The F Market & Wharves is a popular city attraction and extended service hours will allow Muni customers more opportunities to ride historical streetcars this summer.

Pleistocene sediment DNA from Denisova Cave

Pleistocene sediment DNA from Denisova Cave
Researchers have analyzed DNA from 728 sediment samples from Denisova Cave. Their study provides unprecedented detail about the occupation of the site by both archaic and modern humans over 300,000 years. The researchers detected the DNA of Neandertals and Denisovans, the two forms of archaic hominins who inhabited the cave, and the DNA of modern humans who appeared around the time of the emergence of an archaeological culture called the Initial Upper Paleolithic around 45,000 years ago.

Mechanism of magnetic sensing in birds

Mechanism of magnetic sensing in birds
The magnetic sense of migratory birds such as European robins is thought to be based on a specific light-sensitive protein in the eye. Researchers demonstrate that the protein cryptochrome 4, found in birds' retinas, is sensitive to magnetic fields and could well be the long-sought magnetic sensor.

How to make lithium-ion batteries invincible
Scientists have made significant progress in developing battery cathodes using a new class of materials that provide batteries with the same if not higher energy density than conventional lithium-ion batteries but can be made of inexpensive and abundant metals. Known as DRX, which stands for disordered rocksalts with excess lithium, this novel family of materials was invented less than 10 years ago and allows cathodes to be made without nickel or cobalt.

A new study in U.S.-born children from Spanish-speaking families finds that minority language exposure does not threaten the acquisition of English by children in the U.S. and that there is no trade-off between English and Spanish. Rather, children reliably acquire English by age 5, and their total language knowledge is greater to the degree that they also acquire Spanish. Children's level of English knowledge was independent of their level of Spanish knowledge.

Boost for mouse genetic analysis
To understand what role an individual gene plays, biologists have, for 100 years, been using a trick of nature: While in principle, the genome in all cells of an organism is the same, mutations arise in individual cells. These mutations differentiate a cell from its neighbors, forming a 'genetic mosaic.' Now, researchers have advanced genetic mosaic analysis, making almost all genes in the mouse genome accessible to single-cell genetic mosaic analysis.

Will a reduction in tau protein in brain neurons protect against Parkinson's disease and Lewy body dementias? A new study suggests the answer is no. If this is borne out, that result differs from Alzheimer's disease, where reducing endogenous tau levels in brain neurons is protective for multiple models of the disease -- and thus suggests that the role of tau in the pathogenesis of Lewy body dementias is distinct from Alzheimer's disease.
