They don’t eat the grass itself; instead they help the meadows grow by clearing the way for sunlight to reach the plants, scraping the blades of grass clean with their rows of tiny teeth.

At Elkhorn Slough off of the Monterey Bay, the eelgrass beds form a habitat for a diverse community of animals and plant life, which includes sea otters, Dungeness crabs, clams, skeleton shrimp and various fish.\u003c/span>\u003c/p>\n\u003cp>\u003cspan style=\"font-weight: 400\">“Eelgrass is like the ugly duckling of the charismatic habitat world,” says biologist Grace Ha of UC Davis, who studied the camouflage of the Taylor’s sea hare. “Seagrasses are among the most productive habitats in the world, if you compare them to rainforest or coral reefs, but most people don’t even know what eelgrass is.”\u003c/span>\u003c/p>\n\u003cp>[ad fullwidth]\u003c/p>\n\u003cp>\u003cspan style=\"font-weight: 400\">Eelgrass forms submarine meadows in shallow seawater, estuaries and salt marshes across the Northern Hemisphere. Seagrasses absorb carbon from the atmosphere and prevent coastal erosion, but climate change, and human activities like large-scale agriculture threaten their existence worldwide. Biologists compare the steady decline of seagrass beds to the global crises of disappearing rainforests and coral reefs.\u003c/span>\u003c/p>\n\u003cp>\u003cspan style=\"font-weight: 400\">For decades, the eelgrass meadows of Elkhorn Slough were also disappearing. Since the 1950s nitrogen-based fertilizers from farms in the Salinas Valley have drained into the estuary, overloading the water with nutrients, causing massive algae blooms. Too much algae living on the surface of the water blocks the sunlight necessary for eelgrass meadows to grow, and the grasses begin to die out. \u003c/span>\u003c/p>\n\u003cfigure id=\"attachment_1970796\" class=\"wp-caption alignleft\" style=\"max-width: 800px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"wp-image-1970796 size-medium\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2020/11/DL719_eelgrass_sea_hare_MW2-800x450.jpg\" alt=\"\" width=\"800\" height=\"450\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2020/11/DL719_eelgrass_sea_hare_MW2-800x450.jpg 800w, https://cdn.kqed.org/wp-content/uploads/sites/35/2020/11/DL719_eelgrass_sea_hare_MW2-1020x574.jpg 1020w, https://cdn.kqed.org/wp-content/uploads/sites/35/2020/11/DL719_eelgrass_sea_hare_MW2-160x90.jpg 160w, https://cdn.kqed.org/wp-content/uploads/sites/35/2020/11/DL719_eelgrass_sea_hare_MW2-768x432.jpg 768w, https://cdn.kqed.org/wp-content/uploads/sites/35/2020/11/DL719_eelgrass_sea_hare_MW2-1536x864.jpg 1536w, https://cdn.kqed.org/wp-content/uploads/sites/35/2020/11/DL719_eelgrass_sea_hare_MW2-2048x1152.jpg 2048w, https://cdn.kqed.org/wp-content/uploads/sites/35/2020/11/DL719_eelgrass_sea_hare_MW2-1920x1080.jpg 1920w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\">\u003cfigcaption class=\"wp-caption-text\">Eelgrass sea hares clean the eelgrass of the microscopic algae that coats it.

By that time, fur traders had hunted otters almost to extinction along the California coast.

This meant the sea hares could get back to work cleaning the eelgrass of excessive algae, enabling the eelgrass to grow again. Researchers call this a trophic cascade, when a top predator, like a sea otter, has a balancing effect on the ecosystem. \u003ccite>(Mike Seely/KQED)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>\u003cspan style=\"font-weight: 400\">Hughes and his colleagues had uncovered a trophic cascade in which the reintroduction of a top predator (in this case the sea otter) results in a balancing effect on the food web.\u003c/span>\u003c/p>\n\u003cp>\u003cspan style=\"font-weight: 400\">In an eelgrass ecosystem like Elkhorn Slough, where nutrient-polluted waters cause regular extreme algal blooms, the “grazers just become really, really important for controlling that algal overgrowth.” When otters were missing and not eating crabs, the crab population grew and ate too many sea hares, so the eelgrass had less help dealing with the suffocating algae growth.\u003c/span>\u003c/p>\n\u003cp>\u003cspan style=\"font-weight: 400\">“The remarkable thing is that the nutrients are still climbing,” Hughes said. “It’s insane how high the nutrients are in that system.” Despite this continued stress on the ecosystem, the eelgrass meadows in Elkhorn Slough have in fact steadily expanded over the past three decades.

The rocks can be very slippery and you don’t want to be alone if you take a spill. And don’t turn your back on the ocean. Rogue waves can sneak up on an unwary visitor. Also watch where you step and avoid damaging the life that calls the intertidal zone home.\u003c/p>\n\u003cp>[ad floatright]\u003c/p>\n\u003cp>Lastly, Gong recommends taking your time and exercising patience. “Just find a good spot and sit there quietly for fifteen minutes and watch everything that happens. Because when you do, all the little animals get used to your presence and they start doing their thing instead of just hiding, waiting for you to leave.”\u003c/p>\n\n",

This episode of Deep Look would not have been possible without her contribution of time and knowledge.\u003c/p>\n\u003cp>One of Gong’s favorite tide pool denizens are sea stars. “We humans have the bias that the way we do things is the best way to do things. But there is an incredible beauty and elegance in simplicity, which is not appreciated by most people.”\u003c/p>\n\u003cp>The fact that sea stars haven’t changed their basic body plan for a few hundred million years just means that it’s an outstanding plan.\u003c/p>\n\u003cp>“So the fact that these animals with no brain live life the way they do, finding food, like finding a place to live, and avoiding being eaten by predators. They do everything we do, but they have different tools to use.”\u003c/p>\n\u003cp>Gong has a few suggestions for visitors to the tide pools. Always go with someone else. The rocks can be very slippery and you don’t want to be alone if you take a spill. And don’t turn your back on the ocean. Rogue waves can sneak up on an unwary visitor. Also watch where you step and avoid damaging the life that calls the intertidal zone home.\u003c/p>\n\u003cp>\u003c/p>\u003c/div>",

Scientists and many members of the public were eager to find out.\u003c/p>\n\u003cp>Anti-abortion groups, however, a key constituency of President George W. Bush, opposed the research, and in 2001 he limited federal funding to a few existing lines of embryonic stem cells, severely curtailing research.\u003c/p>\n\u003cp>Some in the state of California wanted to get around Bush’s restrictions, and Proposition 71 was born.\u003c/p>\n\u003cp>“(T)hey had this demon they could attack in the campaign — the Bush administration,” said David Jensen, author of “California’s Great Stem Cell Experiment,” who also writes the blog \u003ca href=\"http://californiastemcellreport.blogspot.com/\" target=\"_blank\" rel=\"noopener noreferrer\">California Stem Cell Report\u003c/a>. “They could say, ‘This is a great opportunity, and the only way we’re going to get it done is to do it here in California.'”\u003c/p>\n\u003cp>The measure created the California Institute for Regenerative Medicine. The stem cell research agency is unique in the U.S.\u003c/p>\n\u003cp>“No other state has done this kind of level of funding and focus on this kind of thing,” said Jensen. “It’s a really cutting-edge area of science.”\u003c/p>\n\u003cp>\u003cstrong>A Few Successes\u003c/strong>\u003c/p>\n\u003cp>The pace of innovation has been slower than many hoped. As it turned out, grand discoveries were not around the corner, and to date there is no widespread stem cell treatment approved for the public. To date, CIRM has funded more than 64 trials directly and aided in 31 more. Not all have or will result in treatments.\u003c/p>\n\u003cp>But despite the lack of a marquee cure like one for Alzheimer’s or Parkinson’s, the agency has seen some notable triumphs.\u003c/p>\n\u003cp>“Probably one of the most spectacular successes they have certainly so far,” said Jensen, “is clinical trials that have saved the lives of what they say are 40 children.”\u003c/p>\n\u003cp>Those children were born with severe combined immunodeficiency (SCID), commonly known as “bubble baby syndrome,” a rare, generally fatal condition in which a child is born without a working immune system. An \u003ca href=\"https://blog.cirm.ca.gov/2017/07/25/cirm-funded-life-saving-stem-cell-therapy-gets-nod-of-approval-from-fda/\" target=\"_blank\" rel=\"noopener noreferrer\">FDA-approved\u003c/a> gene therapy that grew out of CIRM-funded research can now cure the disease by taking a patient’s own blood stem cells and modifying them to correct the SCID mutation. The altered cells generate new, healthy blood cells and repair the immune system.\u003c/p>\n\u003cp>The FDA has also approved two drugs for rare blood cancers that were developed with CIRM funds.\u003c/p>\n\u003cp>Sandra Dillon, a graphic designer in San Diego, credits one of the drugs with saving her life. She was diagnosed when she was just 28, in 2006. Her doctors told her they would try to manage her symptoms, but that she was going to get progressively sicker.\u003c/p>\n\u003cp>“Even just the idea of a cure or getting better wasn’t even on the table back then,” said Dillon, who is featured in ads for the Yes on 14 campaign.\u003c/p>\n\u003cp>https://www.youtube.com/watch?v=Fv6FFQ1ez2w\u003c/p>\n\u003cp>“I remember just praying and begging into the universe, please, someone just look at my disease, please someone help, who is going to look at this thing.”\u003c/p>\n\u003cp>By 2010, Dillon was extremely ill. She connected with a doctor at UC San Diego who received early-stage funding from CIRM and told her she could take part in clinical trials.\u003c/p>\n\u003cp>“For the first time, there was this moment of, ‘Oh, my gosh! There are researchers doing something. And it could help me and I can get access to it.’ It was amazing.”\u003c/p>\n\u003cp>The drug received FDA approval in 2019, and today Dillon’s cancer has retreated to the point where she can live a normal life.\u003c/p>\n\u003cp>“I love that I am not tethered to a hospital anymore. I can go out on long backpacking trips and hiking and surfing,” she said. “I am a completely different person with this drug. And I have a whole future ahead of me.”\u003c/p>\n\u003cp>The original funding raised by Proposition 71 is running out. Proposition 14 would authorize the sale of a new bond to refill the agency piggy bank. Gov. Gavin Newsom, the UC Board of Regents, and scores of patient advocacy groups also support the measure.\u003c/p>\n\u003cp>Many newspaper editorial boards, however, oppose the proposition, including the San Francisco Chronicle, Mercury News and Los Angeles Times.\u003c/p>\n\u003cp>Right now the state still owes about $1 billion toward the debt created by Proposition 71. If Proposition 14 passes, the yearly price tag to pay off the new bond would be about $260 million per year for about 30 years.\u003c/p>\n\u003cp>One of the selling points of the original proposition was the potential for the state to earn big money in royalties from the treatments it helped develop, says Jeff Sheehy, an HIV patient advocate and the only CIRM board member to oppose Proposition 14.\u003c/p>\n\u003cp>“The promises were made that this would pay for itself. We would be able to pay back the bonds with the … money we would get from royalties, etc., etc.”\u003c/p>\n\u003cp>That has not worked out as envisioned: CIRM estimates it has received less than $500,000 in royalties. Early this year, Forty Seven, a company whose therapies were heavily funded by CIRM, \u003ca href=\"https://www.gilead.com/news-and-press/press-room/press-releases/2020/3/gilead-to-acquire-forty-seven-for-49-billion\" target=\"_blank\" rel=\"noopener noreferrer\">sold\u003c/a> to Gilead for $4.9 billion. While millions went to various researchers, neither CIRM nor the state of California received anything.\u003c/p>\n\u003cp>“One of the flaws in the original measure is that we [the agency] cannot hold stock in the products that we develop,” says Sheehy. “And that’s because the California Constitution says that the state of California cannot, as a government entity, hold equity.”\u003c/p>\n\u003cp>Proposition 14 makes it impossible for the state to use profits from its investment on, say, schools or other funding priorities. Instead, any royalties earned must be fed back into programs to make CIRM-funded treatments more affordable.\u003c/p>\n\u003cp>“What it does is it basically takes all of our returns that we get from this and gives it back to the pharmaceutical and biotech companies,” said Sheehy. “It becomes just a blatant giveaway to these companies when we should be requiring access and requiring fair pricing.”\u003c/p>\n\u003cp>Sheehy says he supports medical research, but doesn’t like the state going into more debt to pay for it. The greater the state’s obligations in bond money, which has to be paid back with interest, the less there is in the general fund, and Sheehy says the state has more pressing needs than stem cell research — things like housing, education and transportation.\u003c/p>\n\u003cp>“The biggest and perhaps the most compelling reason why I feel so strongly that this is not a good idea is that we simply cannot afford it,” he said. “If we think this is so important,” asks Sheehy, “why don’t we just don’t pay for [this research] out of the general fund? It would be cheaper.”\u003c/p>\n\u003cp>Opponents of Proposition 14 also point to longstanding complaints of conflicts of interest among the agency board. Most of the $3 billion distributed by the agency has gone to institutions with connections to board members. Critics say the structural conflicts of interest between the board and agency are not addressed in the new measure. Proposition 14 would balloon an already huge board of 29 members to 35.\u003c/p>\n\u003cp>Funding needs for stem cell research also are not as acute as they were back in 2004. The federal National Institutes of Health now \u003ca href=\"https://report.nih.gov/categorical_spending.aspx\" target=\"_blank\" rel=\"noopener noreferrer\">funds\u003c/a> some basic stem cell research, spending about $2 billion a year, with $321 million of that going toward human embryonic stem cell research. The Trump administration has not reinstated the ban, but has added lengthy paperwork and review \u003ca href=\"https://www.sciencemag.org/news/2019/07/trump-administration-releases-details-fetal-tissue-restrictions\" rel=\"noopener noreferrer\" target=\"_blank\">requirements\u003c/a>. And private ventures, like nonprofits started by tech billionaires, are pouring more money into biotech.\u003c/p>\n\u003cp>The problem with assuming that, says Melissa King, executive director of Americans for Cures, the stem cell advocacy group behind the “Yes on 14” campaign, is that CIRM fills a neglected funding need.\u003c/p>\n\u003cp>“The NIH does not fund clinical trials at nearly the rate that CIRM can and has been,” King said.\u003c/p>\n\u003cp>She says that’s important because of what she calls the “Valley of Death,” where promising early-stage research frequently fails to translate into promising treatments that can be tested in clinical-stage research. (What works well in a test tube often does not work well in an organism.) This weeding-out process is costly but necessary. And it’s where CIRM focused a lot of its effort.\u003c/p>\n\u003cp>“The first- and maybe even second-phase clinical trials, it’s very difficult to get those funded,” King said. “It is too much of a risk for business to take on on its own. Venture [capital] isn’t going there. Angel [funding] isn’t going there.”\u003c/p>\n\u003cp>What voters have to ask themselves, says writer Jensen, is whether stem cell funding is “a high priority for the state of California? Different people make different judgments about that.”\u003c/p>\n\u003cp>CIRM supporters say if Prop. 14 doesn’t pass, critical research will stall. Others say federal and private funding will step in and fill the gap.\u003c/p>\n\u003cp>Absent new funding, the institute expects it will wind down operations leading to a complete sundown in 2023.\u003c/p>\n\u003cp>[ad fullwidth]\u003c/p>\n\u003cp>[ad floatright]\u003c/p>\n",

Her doctors told her they would try to manage her symptoms, but that she was going to get progressively sicker.\u003c/p>\n\u003cp>“Even just the idea of a cure or getting better wasn’t even on the table back then,” said Dillon, who is featured in ads for the Yes on 14 campaign.\u003c/p>\u003c/p>\u003cp>\u003cspan class='utils-parseShortcode-shortcodes-__youtubeShortcode__embedYoutube'>\n \u003cspan class='utils-parseShortcode-shortcodes-__youtubeShortcode__embedYoutubeInside'>\n \u003ciframe\n loading='lazy'\n class='utils-parseShortcode-shortcodes-__youtubeShortcode__youtubePlayer'\n type='text/html'\n src='//www.youtube.com/embed/Fv6FFQ1ez2w'\n title='//www.youtube.com/embed/Fv6FFQ1ez2w'\n allowfullscreen='true'\n style='border:0;'>\u003c/iframe>\n \u003c/span>\n \u003c/span>\u003c/p>\u003cp>\u003cp>“I remember just praying and begging into the universe, please, someone just look at my disease, please someone help, who is going to look at this thing.”\u003c/p>\n\u003cp>By 2010, Dillon was extremely ill. She connected with a doctor at UC San Diego who received early-stage funding from CIRM and told her she could take part in clinical trials.\u003c/p>\n\u003cp>“For the first time, there was this moment of, ‘Oh, my gosh! There are researchers doing something. And it could help me and I can get access to it.’ It was amazing.”\u003c/p>\n\u003cp>The drug received FDA approval in 2019, and today Dillon’s cancer has retreated to the point where she can live a normal life.\u003c/p>\n\u003cp>“I love that I am not tethered to a hospital anymore. I can go out on long backpacking trips and hiking and surfing,” she said. “I am a completely different person with this drug. And I have a whole future ahead of me.”\u003c/p>\n\u003cp>The original funding raised by Proposition 71 is running out. Proposition 14 would authorize the sale of a new bond to refill the agency piggy bank. Gov. Gavin Newsom, the UC Board of Regents, and scores of patient advocacy groups also support the measure.\u003c/p>\n\u003cp>Many newspaper editorial boards, however, oppose the proposition, including the San Francisco Chronicle, Mercury News and Los Angeles Times.\u003c/p>\n\u003cp>Right now the state still owes about $1 billion toward the debt created by Proposition 71. If Proposition 14 passes, the yearly price tag to pay off the new bond would be about $260 million per year for about 30 years.\u003c/p>\n\u003cp>One of the selling points of the original proposition was the potential for the state to earn big money in royalties from the treatments it helped develop, says Jeff Sheehy, an HIV patient advocate and the only CIRM board member to oppose Proposition 14.\u003c/p>\n\u003cp>“The promises were made that this would pay for itself. We would be able to pay back the bonds with the … money we would get from royalties, etc., etc.”\u003c/p>\n\u003cp>That has not worked out as envisioned: CIRM estimates it has received less than $500,000 in royalties. Early this year, Forty Seven, a company whose therapies were heavily funded by CIRM, \u003ca href=\"https://www.gilead.com/news-and-press/press-room/press-releases/2020/3/gilead-to-acquire-forty-seven-for-49-billion\" target=\"_blank\" rel=\"noopener noreferrer\">sold\u003c/a> to Gilead for $4.9 billion. While millions went to various researchers, neither CIRM nor the state of California received anything.\u003c/p>\n\u003cp>“One of the flaws in the original measure is that we [the agency] cannot hold stock in the products that we develop,” says Sheehy. “And that’s because the California Constitution says that the state of California cannot, as a government entity, hold equity.”\u003c/p>\n\u003cp>Proposition 14 makes it impossible for the state to use profits from its investment on, say, schools or other funding priorities. Instead, any royalties earned must be fed back into programs to make CIRM-funded treatments more affordable.\u003c/p>\n\u003cp>“What it does is it basically takes all of our returns that we get from this and gives it back to the pharmaceutical and biotech companies,” said Sheehy. “It becomes just a blatant giveaway to these companies when we should be requiring access and requiring fair pricing.”\u003c/p>\n\u003cp>Sheehy says he supports medical research, but doesn’t like the state going into more debt to pay for it. The greater the state’s obligations in bond money, which has to be paid back with interest, the less there is in the general fund, and Sheehy says the state has more pressing needs than stem cell research — things like housing, education and transportation.\u003c/p>\n\u003cp>“The biggest and perhaps the most compelling reason why I feel so strongly that this is not a good idea is that we simply cannot afford it,” he said. “If we think this is so important,” asks Sheehy, “why don’t we just don’t pay for [this research] out of the general fund? It would be cheaper.”\u003c/p>\n\u003cp>Opponents of Proposition 14 also point to longstanding complaints of conflicts of interest among the agency board. Most of the $3 billion distributed by the agency has gone to institutions with connections to board members. Critics say the structural conflicts of interest between the board and agency are not addressed in the new measure. Proposition 14 would balloon an already huge board of 29 members to 35.\u003c/p>\n\u003cp>Funding needs for stem cell research also are not as acute as they were back in 2004. The federal National Institutes of Health now \u003ca href=\"https://report.nih.gov/categorical_spending.aspx\" target=\"_blank\" rel=\"noopener noreferrer\">funds\u003c/a> some basic stem cell research, spending about $2 billion a year, with $321 million of that going toward human embryonic stem cell research. The Trump administration has not reinstated the ban, but has added lengthy paperwork and review \u003ca href=\"https://www.sciencemag.org/news/2019/07/trump-administration-releases-details-fetal-tissue-restrictions\" rel=\"noopener noreferrer\" target=\"_blank\">requirements\u003c/a>. And private ventures, like nonprofits started by tech billionaires, are pouring more money into biotech.\u003c/p>\n\u003cp>The problem with assuming that, says Melissa King, executive director of Americans for Cures, the stem cell advocacy group behind the “Yes on 14” campaign, is that CIRM fills a neglected funding need.\u003c/p>\n\u003cp>“The NIH does not fund clinical trials at nearly the rate that CIRM can and has been,” King said.\u003c/p>\n\u003cp>She says that’s important because of what she calls the “Valley of Death,” where promising early-stage research frequently fails to translate into promising treatments that can be tested in clinical-stage research. (What works well in a test tube often does not work well in an organism.) This weeding-out process is costly but necessary. And it’s where CIRM focused a lot of its effort.\u003c/p>\n\u003cp>“The first- and maybe even second-phase clinical trials, it’s very difficult to get those funded,” King said. “It is too much of a risk for business to take on on its own. Venture [capital] isn’t going there. Angel [funding] isn’t going there.”\u003c/p>\n\u003cp>What voters have to ask themselves, says writer Jensen, is whether stem cell funding is “a high priority for the state of California? Different people make different judgments about that.”\u003c/p>\n\u003cp>CIRM supporters say if Prop. 14 doesn’t pass, critical research will stall. Others say federal and private funding will step in and fill the gap.\u003c/p>\n\u003cp>Absent new funding, the institute expects it will wind down operations leading to a complete sundown in 2023.\u003c/p>\n\u003cp>\u003c/p>\u003c/div>",

That’s when Bell, Peterson, his wife, bird biologist Lynn Schofield, and volunteer raptor nest monitor Mary Malec discovered Annie nesting at the top of the tower on a wet sandbag and built her a nest out of a plastic tray filled with pea gravel. Gravel is similar to the pebbles or sandy soil they lay their eggs on in the wild and drains well, which allows the parents to keep their eggs warm.

Rachel Carson’s book “Silent Spring,” in 1962, raised the specter that the pesticide DDT harmed eggs.
