There are now 5,600 troops at the southern border in support of CBP, 1,800 of those are in California. 744

SAN FRANCISCO (AP) — University of California President Janet Napolitano, who oversaw historic expansions of the 10-campus system and championed immigrant students, but whose management structure faced criticism and embarrassing scrutiny, said Wednesday she will step down in August 2020.Napolitano, a former homeland security secretary and Democratic governor of Arizona, made the announcement at a meeting of the university system's Board of Regents in Los Angeles."My time at UC has been deeply gratifying and rewarding. I have been honored and inspired every day to serve this institution alongside incredibly dedicated, passionate people," Napolitano said in a statement. "The decision was tough — and this moment, bittersweet — but the time is right."Napolitano, 61, has battled a recurrence of breast cancer but said her health is good and did not play a role in her decision to step down."All of my tests are clear. So that was not a factor in my decision," Napolitano told reporters in a conference call, saying she will complete her seventh year in the job before stepping down."It seemed like a good time to have some fresh blood at the University of California," she said.During her tenure, Napolitano has overseen an expansion of the public university system, enrolling historic numbers of students and making it easier for in-state students to transfer from community colleges to the university system.She oversaw reforms of policies on sexual misconduct and was a staunch supporter of the rights of immigrant students.In 2017, the university joined a lawsuit challenging the Trump administration's decision to rescind the Deferred Action for Childhood Arrivals program, an action that led to injunctions that allowed hundreds of thousands of DACA recipients to extend their authorization to legally live and work in the U.S., including students in the UC system.But Napolitano also was criticized by state lawmakers after a state audit found problems with her office's financial management. A report from State Auditor Elaine Howle in 2016 found that Napolitano's office failed to disclose millions of dollars in reserve funds.It also said Napolitano's top aides had sought to suppress campus criticism of her office in surveys that were supposed to be confidential and sent directly to the state auditor.The investigators found that Napolitano had approved of the plan to review the survey responses. The audit said there was "insufficient evidence" to conclude that she knew of the full range of what her staff was up to or that she directly approved of any interference. But the investigation and subsequent oversight prompted a rare public rebuke by the UC's governing Board of Regents.Napolitano had a distinguished career before coming to California. As a partner in a prominent Phoenix law firm, she represented Anita Hill during the Senate Judiciary Committee's confirmation hearings for Supreme Court Justice Clarence Thomas in 1991. Hill accused Thomas of sexual harassment, which he denied.She was a popular Democratic leader in Republican-controlled Arizona, easily winning re-election by more than 25 points in 2006. She stepped down in 2009 to join President Barack Obama's cabinet as secretary of homeland security, overseeing border security, ramped-up immigration enforcement and efforts to prevent terrorism. She served until 2013, when she became UC president.Napolitano said she will take a year sabbatical before teaching, beginning in the fall of 2021, at the University of California, Berkeley's Goldman School of Public Policy, where she is currently a tenured professor.Napolitano was asked by reporters if she would rule out running for public office or accepting a political post or appointment."I have no intention in those regards, but you never say never," she said.___Associated Press writer Jonathan J.

SEATTLE (AP) — Scientists say an orca who raised worldwide concern when she carried her dead calf for 17 days and more than 1,000 miles almost two years ago is pregnant. The Seattle Times reports Southall Environmental Associates scientist John Durban and marine mammal research director for the nonprofit SR3 Holly Fearnbach recently finished recording drone images of the endangered southern residents and discovered pregnancies amid the J, K, and L pods. According to SR3, whale pregnancies typically last 17-18 months.Pregnancies are not unusual but Tahlequah's pregnancy carries special meaning for a region that grieved the death of her calf along with her. The southern residents are struggling to survive, and most pregnancies are not successful.SR3 says the unsuccessful pregnancies are due to lack of food and nutrition and there are only 73 whales in population. 881

Scientists, doctors and the public are eagerly waiting to hear how effective a COVID-19 vaccine will be and how soon it could be available to everyone. But when the vaccine is ready, some will be racing to be first in line, while others will be cautiously waiting to see how it plays out."Only about half of people get a flu vaccination polls are showing. In terms of the coronavirus, that’s saying that a third to maybe as much as half of the population will not want to get a vaccine," said Arthur Evans, the CEO of the American Psychological Association.Evans is concerned about whether people will be willing to get the COVID-19 vaccine when it comes out. How people are educated about the upcoming vaccine will be crucial."Right now, I think there are a lot of people who want to take a vaccine and to get a vaccine, but if people feel that this has been rushed, that they don’t feel all of the normal safety measures have been taken, it's going to be much harder for people to take that step," explained Evans.Dr. Bali Pulendran, a pathology, microbiology and immunology professor at Stanford University, says just because a COVID-19 vaccine is being expedited doesn't mean it's any less safe."It's a very established, lengthy process. It’s expedited now because of certain technologies such as the mRNA technology that really helps you accelerate this process," said Dr. Pulendran.He says the creation of a vaccine is rigorously tested, first with mice, then primates, and finally, humans. Tens of thousands of people are currently choosing to participate in COVID-19 vaccine trials."And so, this is a development and paradigm that has served vaccinology really well. It's really served it well in terms of enabling the licensure of some 20 or more vaccines," said Dr. Pulendran.Dr. Pulendran says every year, the flu vaccine varies in efficacy. For a good year, it could be 90 percent protective, while the next year, the flu shot may only be 10 percent effective. The COVID-19 vaccine is expected to be 60 percent effective."I think for me, personally, if I saw a vaccine coming out in the next year or so that had a 60 to 70 percent efficacy, that to me would be very encouraging," said Dr. Pulendran.The public, though, may still need some convincing."One of the hardest things for the general public to embrace is the idea of probability. We like to know definitively if something works or not,” said Evans. “The reality is that a vaccine is a probabilistic issue. It's highly likely that you won’t contract, whatever the condition is, but it’s not 100 percent."Evans says the key will be in how the vaccine is marketed to the American public.Dr. Pulendran hopes any positive data and outcomes of the COVID-19 vaccine trial will encourage as many people as possible to get the vaccine when it comes out. 2823
