Signal transduction without signal: Receptor clusters can direct cell movement

Signal transduction without signal: Receptor clusters can direct cell movement
Whether we smell, taste or see, or when adrenaline rushes through our veins, all of these signals are received by our cells via a specific group of receptor proteins called G protein-coupled receptors, which transmit signals to the inside of the cell. Biochemists have now discovered that such receptors can also produce signals even in the absence of an external stimulus: For certain receptors clustering is apparently sufficient.

Don't focus on genetic diversity to save our species
Scientists have challenged the common assumption that genetic diversity of a species is a key indicator of extinction risk. The scientists demonstrate that there is no simple relationship between genetic diversity and species survival. But researchers conclude the focus shouldn't be on genetic diversity anyway; it should be on habitat protection.

ALS neuron damage reversed with new compound

ALS neuron damage reversed with new compound
Scientists have identified the first compound that eliminates the ongoing degeneration of upper motor neurons that become diseased and are a key contributor to ALS (amyotrophic lateral sclerosis), a swift and fatal neurodegenerative disease that paralyzes its victims. In ALS, movement-initiating nerve cells in the brain and muscle-controlling nerve cells in the spinal cord die. After administering the new compound,, the diseased brain neurons stopped degenerating so much that they became similar to healthy control neurons after 60 days of treatment.

Climate impacts drive east-west divide in forest seed production

Climate impacts drive east-west divide in forest seed production
Younger, smaller trees that comprise much of North America's eastern forests have increased their seed production under climate change. But older, larger trees that dominate western forests have been less responsive, a new study warns. This continental divide could limit western forests' ability to regenerate following large-scale diebacks linked to rising temperatures and intensifying droughts. Over time this might dramatically alter the composition and structure of 21st century North American forests.

Virtual Parade and New Central Subway Art Ring in Lunar New Year

Virtual Parade and New Central Subway Art Ring in Lunar New Year
Virtual Parade and New Central Subway Art Ring in Lunar New Year
By Sophia Scherr

We are entering the year of the Ox, typically symbolizing hard work, positivity, and honesty. This year the SFMTA will continue the tradition of celebration with the virtual San Francisco Chinese New Year Parade  on February 20th at 6 pm on KTVU.

Celebrating Lunar New Year and the San Francisco Chinese community has been a long-standing tradition for many of us. In 1849, San Francisco’s population swelled to 50,000 and many of the new residents were Chinese immigrants, coming to work in gold mines or on railroad lines. By the 1860’s, the Chinese were eager to share their culture with others and the annual tradition of parade and pageantry was born. A variety of other cultural groups throughout the city were invited to participate, and they marched down what today are Grant Avenue and Kearny Street with colorful flags, banners, lanterns, and drums and firecrackers to drive away evil spirits. The city’s Chinese New Year Parade is one of the largest celebrations of its kind in the world, attracting over three million spectators and television viewers throughout the U.S., Canada and Asia.

In line with what the year of the Ox signifies, we also look forward to seeing our work come to fruition when the Central Subway Project's Chinatown - Rose Pak station opens in 2022. As part of this milestone, the SFMTA in partnership with SFAC’s Public Art Program, the Chinese Culture Center, Chinatown Community Development Center, and the Chinese Historical Society have envisioned a vibrant art program for Chinatown’s station. Three significant prominent artworks by artists Tomie Arai, Yumie Hou and Clare Rojas are being installed, infusing the quintessential Chinatown spirit into their works, connecting the past, present and future. These artworks also serve as wayfinding – from marking the entrance to the station, to signaling to riders their arrival at Chinatown with placement of prominent works on the platform walls.

Traditional Chinese paper cut artist Yumei Hou developed large murals that will adorn the station

Ongoing community involvement is an essential to ensuring that Chinatown residents had a role in the artwork design process. The Chinese Cultural Center helped convene community meetings so that the artists would be able to meet residents and receive feedback on their proposed designs. Through this support, artists and community members were able to collaborate on the design of the installations. Artist Tomie Arai was able to work with local photographer Bob Hsiang to photograph students from Gordon J. Lau Elementary School who were then featured in her work.

Central Subway Project outreach staff and their partners at the Chinatown Community Development Center wanted to ensure that all aspects of Chinese culture and art were represented in the art program that will adorn the entryway of the stations roof-top plaza. The center conducted a couplet contest that garnered 120 couplet entries from local, national and international poets. San Francisco poet, Carin Mui was selected, her couplet, a form of Chinese poetry with two lines of verse that have a joined meaning and follow a list of exacting rules reads “In the past, we traveled across the Pacific to mine for gold; Now, we break through earth to form a silver dragon.”

Artist Terry Luk paints the winning couplet for the Chinatown Central Subway Station, as composer Carin Mui, former Chinatown Community Development Center staffer Jerri Diep and former Central Subway Program Manager John Funghi look on.

Public art in our stations is important not only for its aesthetic or beauty, but helps draw out the identity of a space, aids in the understanding of the historic or cultural significance of a neighborhood and builds a connection between visitor and the surrounding community. It’s an important reminder of the power of art to address the complexity and diversity of neighborhoods and to maintain cultural identity in the face of rapid urban transformation.

Proper fit of face masks is more important than material, study suggests

Proper fit of face masks is more important than material, study suggests
Researchers studying the effectiveness of different types of face masks have found that in order to provide the best protection against COVID-19, the fit of a mask is as important, or more important, than the material it is made of.

Researchers propose that humidity from masks may lessen severity of COVID-19
Masks help protect the people wearing them from getting or spreading SARS-CoV-2, the virus that causes COVID-19, but now researchers have added evidence for yet another potential benefit for wearers: The humidity created inside the mask may help combat respiratory diseases such as COVID-19.

Identifying risk factors for elevated anxiety in young adults during COVID-19 pandemic

Identifying risk factors for elevated anxiety in young adults during COVID-19 pandemic
A new study has identified early risk factors that predicted heightened anxiety in young adults during the coronavirus (COVID-19) pandemic. The findings from the study could help predict who is at greatest risk of developing anxiety during stressful life events in early adulthood and inform prevention and intervention efforts.

Limited transmission of COVID-19 from open schools but teachers were affected: Swedish study

Limited transmission of COVID-19 from open schools but teachers were affected: Swedish study
In Sweden, upper-secondary schools moved online while lower-secondary schools remained open during the spring of 2020. A comparison of parents with children in the final year of lower-secondary and first year of upper-secondary school shows that keeping the former open had limited consequences for the overall transmission of the virus. However, the infection rate doubled among lower-secondary teachers relative to upper-secondary ones.

NIH experts discuss SARS-CoV-2 viral variants

NIH experts discuss SARS-CoV-2 viral variants
The rise of significant variants of SARS-CoV-2 has attracted the attention of health and science experts worldwide. In a new editorial, experts outline how these variants have arisen, concerns about whether vaccines currently authorized for use will continue to protect against new variants, and the need for a global approach to fighting SARS-CoV-2 as it spreads and acquires additional mutations.
