Despite progress made in confocal microscopy, even fast systems still have insufficient temporal resolution for detailed live cell volume imaging, such as tracking rapid movement of membrane vesicles in three-dimensional space. Depending on the shortfall, this may result in undersampling and/or motion artifacts that ultimately limit the quality of the imaging data. By sacrificing detailed information in the Z-direction, we propose a new imaging modality that involves capturing fast "projections" from the field of depth which shortens imaging time by approximately an order of magnitude as compared to standard volumetric confocal imaging. With faster imaging, radiation exposure to the sample is reduced, resulting in less fluorophore photobleaching and potential photodamage. The implementation minimally requires two synchronized control signals that drive a piezo stage and trigger the camera exposure. The device generating the signals has been tested on spinning disk confocals and instant structured-illumination-microscopy (iSIM) microscopes. Our calibration images show that the approach provides highly repeatable and stable imaging conditions that enable photometric measurements of the acquired data, in both standard live imaging and super-resolution modes.

A Los Angeles Unified School District employee filed suit Wednesday accusing Superintendent Ramon Cortines of sexual harassment and retaliation, and alleging officials failed to intervene when told of the situation.

The lawsuit is the third one filed by Scot Graham, LAUSD's real estate director, who has made similar charges in previous complaints. The suit was filed in Los Angeles County Superior Court.

LAUSD General Counsel David Holmquist issued a statement Tuesday saying the courts have previously ruled on the case and the district is not aware of any new charges. "This is simply a frivolous refiling of the same allegations," he stated.

The latest suit alleges Cortines made sexual advances to Graham in 2000 soon after Cortines helped Graham get a job with the school district’s real estate leasing operations. Cortines left the school district that same year and Graham didn’t report what allegedly happened, according to the suit.

Graham claims that Cortines made additional sexual advances in 2010, the year the school board hired Cortines a second time to run the school district. The sexual advances were made at Cortines’ second home in Kern County, the suit alleges.

“Cortines’ advance shocked and disturbed Graham, who feared that declining Cortines’ request for sex would lead to unwarranted retaliatory consequences,” according to the lawsuit.

Graham said he notified his boss John Creer, and his boss’ boss James Sohn, but the school district conducted no investigation. Then in an October 2010 meeting, the suit claims General Counsel Holmquist “discouraged Graham from pursuing his claims, and suggested, in an intimidating and patronizing manner, that the incidents at the Ranch and Cortines’ unsolicited phone call were better left unreported.”

In May 2012, the district announced that it would pay $200,000 to Graham to settle his sexual harassment claims against Cortines, who by then had left the post. In the announcement, the district said Cortines denied sexually harassing Graham, but acknowledged they had a consensual relationship.

Graham later declined to sign off on the settlement. He filed one lawsuit in 2013 that was dismissed on a legal technicality and then a second one that was withdrawn in May 2014.

Five months later, the LAUSD school board rehired Cortines as an interim superintendent after the resignation of his predecessor, John Deasy. Cortines is expected to serve until a permanent replacement is chosen by the board later this year.

“What makes this different and new is the school board has rehired Ramon Cortines despite documented history of sexual harassment and sexual assault against Scot Graham,” said Rob Hennig, Graham’s lawyer.

By failing to investigate whether there was any merit to Graham’s allegations, the lawsuit argues, the school district failed in its duty to protect an employee from potential sexual harassment.

“Cortines shouldn’t have been rehired by the school board,” Hennig said.

In his statement, Holmquist said the district intends to "seek reimbursement for the taxpayers' dollars that are having to be expended in attorney's fees and costs" in dealing with Graham's allegations. The district said it spent about $240,000 defending itself against Graham's first two lawsuits.

Graham said in an interview Tuesday that he has been on leave since late last year because he’s developed a type of seizure disorder that prevents him from driving long distances.

He said he filed the latest lawsuit after the school board rehired Cortines and he was running into him in the workplace. Graham also said he felt his allegations were swept under the rug.

“No one came to talk to me…it was like being in a fraternity house,” he said.

The suit does not say how much in damages Graham is seeking, but it asks among other items for back pay, future pay, benefits, and compensation for medical treatment. It also seeks an investigation into Graham's accusations against the superintendent.

While the U.S. Department of Veterans Affairs (VA) provides mental health care of comparable or superior quality to care provided in private and non-VA public sectors, accessibility and quality of services vary across the VA health system, leaving a substantial unmet need for mental health services among veterans of the recent wars in Afghanistan and Iraq, says a new congressionally mandated report from the National Academies of Sciences, Engineering, and Medicine.

All five members of the Los Angeles County Board of Supervisors have signed a letter imploring California Gov. Jerry Brown to intervene in the state’s handling of contamination around the Exide Technologies plant in Vernon.

The letter criticizing the state’s “piecemeal approach to an urgent environmental hazard” comes as workers paid for by Exide are removing lead-contaminated topsoil from two homes near the intersection of Olympic and Indiana avenues in L.A. 

Signed Tuesday, the letter asks for “guaranteed state funding to immediately begin testing” at 37 more homes also sampled, but to less specific degrees, during November 2013. In the words of the board, “further testing and remediation of the other 37 homes has not been confirmed and may not begin until at least October 2014 because Exide has not yet agreed to comply with DTSC directives issued last March.”

The supervisors also say the state has “reneged” on its commitments to test for lead inside the homes as well as outside.

The Department of Toxic Substances Control says that the two homes workers are at this week will be cleaned inside and out — even without indoor testing.  The DTSC’s Rizgar Ghazi said Monday that crews will use HEPA filters, vacuums and shampooing equipment on “basically any flat surface” inside the two residences.

After the cities of San Clemente and Laguna Beach were given the OK by state officials on Monday to reopen beaches with limited conditions, the California Natural Resources Agency gave Dana Point, Seal Beach and Huntington Beach the green light on Tuesday after approving the plans they submitted for safe reopening.

The plans vary as far as when the beach can be used, but the common thread through each is that leisure activities like sunbathing or large gatherings of people would not be allowed, and that beachgoers will be required to remain active while on the sand. 

The news comes as Orange County Supervisors voted 3-2 on Tuesday to submit a plan to submit to Sacramento that would create a set of uniform rules for reopening beaches countywide. Supervisor Lisa Bartlett spearheaded the proposal, which received pushback from Supervisors Don Wagner and Michelle Steel who argue that after being singled out by Governor Gavin Newsom last week when he ordered a “hard close” on all state and local beaches in Orange County, taking issue with the idea of the county bowing to pressure from the state.

Today on AirTalk, we’ll check back in with Supervisor Bartlett, who joined us Monday on AirTalk, to find out more about the specifics of the county’s plan to reopen its beaches.

Connecting Europe and North Africa with a single, long-distance electricity ‘supergrid’ is technically possible and the cheapest option available to meet Europe’s renewable energy targets, according to new research. However, significant political challenges, such as minimising the perception of risk and attracting sufficient investment, need to be overcome.

A study has evaluated three types of media campaign conducted by a large UK supermarket to encourage shoppers to reduce their food waste. These used social media, an e-newsletter and a print/digital magazine, respectively. Although they all appeared to lead to reductions in food waste to some extent, similar behavioural changes were also seen for customers who had not participated in any of the campaigns.

Researchers have examined environmental and economic impacts of supermarket food waste in a new study. Bread and meat products made the largest contribution to the environmental footprint of the supermarket assessed. Alternative waste strategies, such as using bread waste as animal feed, have the potential to reduce these impacts.

Polarised light forms the basis of many technologies, such as computer monitors. However, current approaches for making polarised light are inefficient, as they produce more than is ultimately used or needed. Researchers may now have found a way to directly produce polarised light using tiny nanostructures, called quantum dots, opening the way for more energy-efficient technologies.
