California voters reject 2 housing-affordability measures

By Megan Myscofski

Californians voted on two housing-related measures Tuesday — Propositions 5 and 33 — and rejected both, according to respective Associated Press race calls. Still, many voters cited affordability as a major issue in the state. 

Proposition 33 would’ve rolled back state-wide restrictions on rent control. Proposition 5 would’ve made it easier for local governments to approve bonds for affordable housing, among other projects. 

Mary-Beth Moylan is a law professor at the University of the Pacific. She said the rejection is a sign voters think lawmakers should solve the problem. 

“Maybe the messaging is — we want there to be changes, we want there to be more affordable housing,” she said. “But we want the Legislature to figure out how to do it on its own and not involve the voters.”

But she added that could be bad news for local officials tasked with addressing affordability in their communities. 

“The fact that these two measures didn't pass means that those people will not have, really, the tools that they need to get anything done,” she said. 

Moylan said attack ads probably played a large part in the no votes, too. 

“There were effective campaigns that had people not really understanding what both of them would do and what the consequences of them would be,” she said. 

She also said that when voters don’t understand a measure, they tend to vote it down. 

“Which I'm not saying is a bad thing,” she added. “Because we probably shouldn't be voting for things that we don't understand.” 

Either way, Moylan said that voters didn’t see these as viable solutions to California’s housing affordability problem.

Here’s what we know about California 2024 General Election results so far

By Laura Fitzgerald

Updated Nov. 8, 4:30 p.m.

Polls are closed in California. Elections officials are beginning to process and count millions of mail-in ballots from California’s General Election.

The Secretary of State’s Office website shows an estimated 10,728,985 ballots had been counted by Friday at 4:30 p.m.

Every registered California voter was sent a mail-in ballot. The process offers greater convenience for voters, but also delays results because election staff must spend more time verifying signatures and handling late-arriving ballots.

Leading up to the election, statewide ballot returns were slightly lower compared to the 2020 General Election. On Monday, roughly 42% of ballots had been returned; in 2020, that number was closer to 49%, according to election firm Political Data, Inc.

County election officials have until Dec. 5 to process and count ballots. The Secretary of State will certify the results of the election on Dec. 13.

This page will be updated as results come in. See full California election results here

Presidential race

Vice President Kamala Harris won California’s 54 electoral college votes, according to a call by the Associated Press. (California’s electoral college lost one member after the 2020 census.) Harris’s projected win was called immediately after polls closed, far from a surprise in California. 

The presidential race was called for Donald Trump by the Associated Press early Wednesday morning.

U.S. Senate

Democratic Representative Adam Schiff has won the race to fill the U.S. Senate seat held for decades by the late Sen. Dianne Feinstein, according to a call made by the Associated Press shortly after polls closed. He had 57.6% of the preliminary results on Friday afternoon. 

Republican challenger (and former Los Angeles Dodgers baseball star) Steve Garvey had 42.4% of early results Friday afternoon.

U.S. Senate (special election)

A special election to fill the remainder of Feinstein’s senate term also appeared on the ballot this election. The seat is currently held by Sen. Laphonza Butler, who was appointed as a caretaker by Governor Gavin Newsom shortly after Feinstein’s death. 

Schiff was also announced as the winner of this race, per the Associated Press.

U.S. House of Representatives

District 3: 

Republican incumbent Rep. Kevin Kiley won the race Congressional District 3, according to a race call by the Associated Press. He led with 57.2% of the vote on Friday afternoon.

Democratic challenger Jessica Morse followed with 42.8% of early results Friday afternoon. Morse previously ran against Rep. Tom McClintock in 2018.

Morse conceded in a message to supporters posted on social media on Friday.

"Although we didn't have the outcome we wanted in this race, I am proud to have stood at a critical juncture in history with you," she said. "We sounded the alarm, mobilized neighbors and awoke civic engagement in our community. I know it feels like a red tsunami has come to wipe out our freedoms. But our work together over the previous year, knocking doors, making calls, writing postcards, has communicated directly to our community and helped reinforce the foundations of our democracy." 

District 6:

Democratic incumbent Ami Bera won the race for Congressional District 6, according to a race call from the Associated Press. He had 57.3% of early results on Friday. Bera, who was first elected in 2012, has served on the Science, Space and Technology and Foreign Affairs committees, among others, during his time in Congress.

Republican realtor and financial investigator Chris Bish followed with 42.7% of early results Friday.

District 7: 

Democratic incumbent Doris Matsui won her 11th two-year term in the House, according to a call by the Associated Press. Matusi, who was elected in 2005, had 65.4% of early results Friday afternoon.

Republican challenger Tom Silva followed with 34.6%. Silva served as a member of the armed forces for 33 years and on the school board in his hometown of Galt.

California’s 7th Congressional District includes central and south Sacramento neighborhoods including Downtown, Midtown, Arden-Arcade, Lemon Hill and Florin along with the cities of West Sacramento and Elk Grove.

California voters pass $10B bond measure funding environmental projects

By Manola Secaira

California voters passed Proposition 4, according to a race call by the Associated Press. About 58% of voters statewide supported the measure that will issue $10 billion in bonds for climate-related projects. 

The money will fund a variety of projects, including those that boost access to safe drinking water, wildfire prevention and the protection of lands and communities in California. 

“The way that Prop 4 was designed to focus on prevention and preparedness really represents  a pivotal shift away from just reacting to climate change,” said Guillermo Rodriguez, the California state director for the conservation nonprofit Trust for Public Land.

Rodriguez said he sees Proposition 4’s passage as evidence of increased voter interest in projects that tackle climate change impacts. 

“The voters of California are willing to make these kinds of significant investments in the future because I think we're all being impacted by climate change,” he said. 

He says the measure will help his nonprofit’s efforts to make public lands more accessible. The measure promises $700 million toward expanding and renovating local and state parks. 

Ariana Rickard, the public policy and funding program manager for the conservation nonprofit Sonoma Land Trust, said she’s expecting 2025 to be another deficit year for California’s budget. This has previously meant slashed funding for environmental projects. 

But she said this money ensures nonprofits who rely on state funding from agencies like the Wildlife Conservation Board — which will receive funding from the measure — can continue their work regardless of budget cuts.  

“We're really thrilled because it means that our projects can go forward,” Rickard said. “There's not going to be added delays to the timeline because we have that reassurance that that funding will be there.”

Here’s what we know about how California voted on 2024 state propositions so far

By Claire Morgan

Updated Nov. 8, 4:55 p.m.

Polls have closed in California and initial results are starting to come in. It may take days — or even weeks — for many races to be called, with results coming in waves as mail-in ballots are received and counted. 

We've noted where the Associated Press has called whether a measure will succeed or fail. CapRadio and NPR rely on the Associated Press for race calls. Here is information on when to expect results and how the process works.

?Proposition 2

California voters approved Proposition 2, according to a race call by the Associated Press. Early results show out of 10,386,227 ballots counted, 57.1% were for and 42.9% were against issuing $10 billion in bonds to improve facilities at public schools and community colleges. Funds raised through these bonds will go toward new construction, including land purchases and classroom upgrades.

?Proposition 3

California voters approved Proposition 3, according to a race call by the Associated Press. Early results show out of the 10,437,201 ballots counted, 61.4% were for and 38.6% were against amending California’s Constitution to remove language which states marriage is permitted only between man and woman. 

The language was added to the state’s Constitution in 2008 after voters passed Proposition 8, but is unenforceable due to the U.S. Supreme Court’s landmark Obergefell v. Hodges case which requires all states to license same-sex marriages.

?Proposition 4

California voters approved Proposition 4, according to a race call by the Associated Press. Early results show out of the 10,455,468 ballots counted, 58.2% were for and 41.8% were against issuing $10 billion in bonds to fund climate-related projects. 

Funds raised by the measure will go towards improving access to drinkable water, land conservation, wildfire prevention and reducing the impacts of extreme weather on California communities. California’s Legislative Analyst’s Office estimates it will take $400 million annually over 40 years for the state to repay the bond.

?Proposition 5 

California voters rejected Proposition 5, according to a race call by the Associated Press. Early results show out of the 10,351,394 ballots counted, 56.2% were against and 43.8% were for lowering the statewide threshold to approve housing and infrastructure-related bonds to 55%. 

Currently, bonds require the support of two-thirds of those voting to be approved. 

Proposition 6

Early results show out of the 10,196,270 ballots counted, 54.7% were against and 45.3% were for banning involuntary servitude as a punishment for crime in California. 

According to the Legislative Analyst’s Office, about one-third of people in California prisons work jobs like cooking, cleaning, or other tasks needed to run prisons and jails. California’s Reparations Task Force recommended the measure in its 2023 report.

Proposition 32

Early results show out of the 10,458,925 ballots counted, 51.9% were against and 48.1% were for raising the statewide minimum wage to $18 in 2026. If passed, Proposition 32 would also require minimum wage to be adjusted for inflation in the years after it went into effect. 

Past state legislation has also increased wages for workers in the fast food industry and certain healthcare workers. These local and industry-specific wages would be unaffected by Proposition 32.

?Proposition 33

Californians rejected Proposition 33, according to a race call from the Associated Press. Early results show out of the 10,339,438 ballots counted, 61.5% were against and 38.5% were for allowing local governments to set their own rent control laws with fewer restrictions.

If Proposition 33 were to have passed, it would have repealed a 1995 state law called the Costa-Hawkins Rental Housing Act, which prevented cities from implementing rent control on single-family homes or housing built on or after February 1, 1996. 

Proposition 34

Early results show out of the 10,037,466 ballots counted, 51.3% were for and 48.7% were against requiring health care providers to spend 98% of the revenue they gather on direct patient care. 

The language of the measure establishes a high bar for which health care entities would be required to abide by these restrictions, if passed. These entities must be participants of the discount prescription drug program and spend over $100 million on “purposes that do not qualify as direct patient care” over 10 years. Currently, the AIDS Healthcare Foundation is the only organization in California that would meet the standards outlined in the measure.

?Proposition 35

California voters approved Proposition 35, according to a race call by the Associated Press. Of the the 10,306,197 ballots counted, 66.9% were for and 33.1% were against bolstering California medicaid reimbursements by ensuring funds the Managed Care Organizations tax go toward Medi-Cal services.

?Proposition 36

California voters have approved Proposition 36, according to a race call by the Associated Press. Of the 10,400,928 ballots counted, 70.1% were for and 29.9% were against raising penalties for some crimes by repealing aspects of a 10-year old proposition that decreased them to address prison overcrowding.

The previous measure, Proposition 47, lowered some theft and drug-related crimes from a felony to a misdemeanor when it was passed in 2014. The new measure would generally turn these misdemeanors back into felonies. It would also lengthen some prison sentences and require more felonies be served in prison. Courts would also be able to mandate drug treatment for people charged with possessing illegal drugs.

The artificial lake is an important water reservoir for the thirsty people of southern California, so the Casitas Municipal Water District takes its cleanliness very seriously.

The lake is popular among boaters and fishermen. After a few hours out on the water, people need to relieve themselves. They can then paddle up to the S.S. Relief, which is a 2-seater outhouse that floats on the surface of the water. The waste is contained on the barge, so there's no contamination of the lake's purity.

Islamic radicalisation in Central Asia

Islamic radicalisation in Central Asia 18 September 2024 — 10:00AM TO 11:30AM Anonymous (not verified) Chatham House and Online

Experts analyse rising foreign recruitment, current counter-radicalisation efforts and challenge past Chatham House predictions made of the Central Asia region.

In 2014, Chatham House released a report titled The Myth of Post-Soviet Muslim Radicalisation in the Central Asian Republics. At that time, a significant, Western-funded counter-radicalisation industry was addressing what was believed to be a major issue of Islamic violent extremism in the region.

Over the past decade, two key developments have occurred. First, Western interest in the region has declined in favour of traditional geopolitical concerns. Second, while violent extremism incidents within Central Asia remain rare, there has been a notable recruitment of Central Asians by foreign groups, with several attacks carried out by Central Asians overseas.

In this event, the original report’s authors, John Heathershaw and David Montgomery, will discuss whether the report’s arguments are still valid and how we might answer these questions today.

This raises several questions:

  • What did the report accurately predict, and where did it fall short?
  • How can we explain the lack of violent extremist organisations (VEOs) within Central Asia but the presence of Central Asians in VEOs abroad?
  • Could repression by Central Asian states both domestically and transnationally have contributed to this issue?
  • What, if anything, can the counter-radicalisation industry do today to address this problem more effectively?

Please note that in-person places are limited. Please wait for confirmation before participating.

The amphipathic helices of Arfrp1 and Arl14 are sufficient to determine subcellular localizations [Cell Biology]

The subcellular localization of Arf family proteins is generally thought to be determined by their corresponding guanine nucleotide exchange factors. By promoting GTP binding, guanine nucleotide exchange factors induce conformational changes of Arf proteins exposing their N-terminal amphipathic helices, which then insert into the membranes to stabilize the membrane association process. Here, we found that the N-terminal amphipathic motifs of the Golgi-localized Arf family protein, Arfrp1, and the endosome- and plasma membrane–localized Arf family protein, Arl14, play critical roles in spatial determination. Exchanging the amphipathic helix motifs between these two Arf proteins causes the switch of their localizations. Moreover, the amphipathic helices of Arfrp1 and Arl14 are sufficient for cytosolic proteins to be localized into a specific cellular compartment. The spatial determination mediated by the Arfrp1 helix requires its binding partner Sys1. In addition, the residues that are required for the acetylation of the Arfrp1 helix and the myristoylation of the Arl14 helix are important for the specific subcellular localization. Interestingly, Arfrp1 and Arl14 are recruited to their specific cellular compartments independent of GTP binding. Our results demonstrate that the amphipathic motifs of Arfrp1 and Arl14 are sufficient for determining specific subcellular localizations in a GTP-independent manner, suggesting that the membrane association and activation of some Arf proteins are uncoupled.

Characterization of essential domains in HSD17B13 for cellular localization and enzymatic activity [Research Articles]

Human genetic studies recently identified an association of SNPs in the 17-β hydroxysteroid dehydrogenase 13 (HSD17B13) gene with alcoholic and nonalcoholic fatty liver disease development. Mutant HSD17B13 variants devoid of enzymatic function have been demonstrated to be protective from cirrhosis and liver cancer, supporting the development of HSD17B13 as a promising therapeutic target. Previous studies have demonstrated that HSD17B13 is a lipid droplet (LD)-associated protein. However, the critical domains that drive LD targeting or determine the enzymatic activity have yet to be defined. Here we used mutagenesis to generate multiple truncated and point-mutated proteins and were able to demonstrate in vitro that the N-terminal hydrophobic domain, PAT-like domain, and a putative α-helix/β-sheet/α-helix domain in HSD17B13 are all critical for LD targeting. Similarly, we characterized the predicted catalytic, substrate-binding, and homodimer interaction sites and found them to be essential for the enzymatic activity of HSD17B13, in addition to our previous identification of amino acid P260 and cofactor binding site. In conclusion, we identified critical domains and amino acid sites that are essential for the LD localization and protein function of HSD17B13, which may facilitate understanding of its function and targeting of this protein to treat chronic liver diseases.

PLRP2 selectively localizes synaptic membrane proteins via acyl-chain remodeling of phospholipids [Research Articles]

The plasma membrane of neurons consists of distinct domains, each of which carries specialized functions and a characteristic set of membrane proteins. While this compartmentalized membrane organization is essential for neuronal functions, it remains controversial how neurons establish these domains on the laterally fluid membrane. Here, using immunostaining, lipid-MS analysis and gene ablation with the CRISPR/Cas9 system, we report that the pancreatic lipase-related protein 2 (PLRP2), a phospholipase A1 (PLA1), is a key organizer of membrane protein localization at the neurite tips of PC12 cells. PLRP2 produced local distribution of 1-oleoyl-2-palmitoyl-PC at these sites through acyl-chain remodeling of membrane phospholipids. The resulting lipid domain assembled the syntaxin 4 (Stx4) protein within itself by selectively interacting with the transmembrane domain of Stx4. The localized Stx4, in turn, facilitated the fusion of transport vesicles that contained the dopamine transporter with the domain of the plasma membrane, which led to the localized distribution of the transporter to that domain. These results revealed the pivotal roles of PLA1, specifically PLRP2, in the formation of functional domains in the plasma membrane of neurons. In addition, our results suggest a mode of membrane organization in which the local acyl-chain remodeling of membrane phospholipids controls the selective localization of membrane proteins by regulating both lipid-protein interactions and the fusion of transport vesicles to the lipid domain.
