(Beyond Pesticides, August 23, 2016) “Fundamentally anti-consumer,” said U.S. Senator Richard Blumenthal (D-CT) of the new genetic engineered (GE) labeling bill signed into law by President Obama late last month. Senator Blumenthal’s frustration with the new legislation and its preemption of state-level laws such as Vermont and Connecticut’s led the Senator to announce he will be introducing a bill next session to repeal the divisive law. After years of state-level ballot initiatives in California, Oregon, Washington State, and Colorado, which were defeated after the chemical industry poured millions of dollars into ad buys that played on consumer fears of higher prices at the check-out line, Maine and Connecticut took a stand for consumer’s right to know. While their legislation required trigger clauses to go into effect, Vermont’s was passed shortly after without such a clause, and withstood a legal challenge from the multinational food and chemical industry. Vermont’s law propelled industry to move its efforts to Congress, and the state’s legislation actually went into effect on July 1, 2016, as industry was still working to garner the necessary votes for its new DARK deal.   Pushed forward by Senators Debbie Stabenow (D-MI) and Pat Roberts (R-KS), the new law has […]

(Beyond Pesticides, August 22, 2016) An invasive whitefly that is resistant to pesticides has been found outdoors in the U.S. for the first time, prompting a public discussion hosted by the University of Florida Extension Miami-Dade in Homestead, Florida on July 29. And while the fears amongst fruit and vegetable growers over crop devastation are valid, little attention has been paid to the viability and effectiveness of organic and cultural management practices in preventing and managing  whiteflies. Meanwhile, chemical intensive agriculture, which is dependent on insecticides to control whiteflies, is harming the same beneficial insects that act as natural predators to the whitefly. The pest, a Q-biotype of the sweet potato whitefly, Bemisia tabaci, has been present in greenhouses around the U.S. since 2004, when it was first found in Arizona. According to Florida Agriculture Commissioner Adam Putnam, this pest “poses a serious risk to Florida’s $120 billion agriculture industry and the more than two million jobs it supports.” Whiteflies are tiny, fluid-sucking insects that thrive in warm weather and become abundant in ornamental and vegetable plantings. This particular species breed year round and large colonies often develop on the undersides of leaves. Whiteflies draw fluid of out a plant […]

(Beyond Pesticides, August 19, 2016) A study published earlier this week has found that the increasing use of neonicotinoid (neonic) insecticides is correlated with a steep decline in butterfly health and reproductive success — as more neonics are used, butterflies are struggling to survive. This study adds to previous evidence that demonstrates, in addition to bees, neonics can cause serious harm to other important pollinators. The study, Increasing neonicotinoid use and the declining butterfly fauna of lowland California, looks at 67 species of butterfly fauna in the lowlands of Northern California at four sites that were  monitored for approximately 30-40 years. The sites include Suisun Marsh, West Sacramento, North Sacramento, and Rancho Cordova. While controlling for land use and other factors, the researchers found a correlation between butterfly population decline and increasing neonic applications, which also appeared to be more severe for smaller-bodied species. According to the researchers, the results suggest that neonics could influence non-target insect populations when applied nearby. This study contributes to the mounting evidence that neonicotinoid insecticides are linked to pollinator decline. Neonics have increasingly been the subject of studies that highlight a relationship between neonicotinoid exposure  and harmful effects to pollinators. These effects are being […]

(Beyond Pesticides, August 18, 2016)   Decline of wild bee populations is linked to the use of toxic, systemic neonicotinoid (neonic) pesticides used on oilseed rape (canola), according to new research done by a team of scientists at the Centre for Ecology and Hydrology in the United Kingdom. In addition to corn and soybeans, canola is one of the main crops treated with neonicotinoids worldwide. Neonic pesticides have long been identified as a major culprit in bee decline by independent scientists and beekeepers, yet chemical manufacturers like Bayer and Syngenta have focused on  other issues such as the varroa mite. As Beyond Pesticides put it in the spring 2014 issue of Pesticides and You, the issue of pollinator decline is No Longer a Big Mystery, and urgent action is needed now to protect pollinators from these toxic pesticides. Neonics are associated with decreased learning, foraging and navigational ability, as well as increased vulnerability to pathogens and parasites as a result of suppressed bee immune systems. In addition to toxicity to bees, pesticides like neonicotinoids have been shown to also adversely affect birds, aquatic organisms and contaminate soil and waterways, and overall biodiversity. The study, Impacts of neonicotinoid use on long-term […]

(Beyond Pesticides, August 16, 2016) Young children are disproportionately poisoned by toxic pesticides used indoors, according to a study published in the Australian and New Zealand Journal of Public Health. Data analyzed from the Queensland, Australia Poisons Information Centre (QPIC) finds that 49% of 743 insecticide-related calls in 2014 concerned young children. Given that children are more sensitive to pesticide exposure than adults because they take in more of a chemical relative to their body size and have developing organ systems, this data underscores the importance of educating the general public about alternatives to the use of toxic pesticides in and around the home. A significant share of childhood pesticide poisonings occurred in very young children. “Children in the one-year age group were at greatest risk — as they’re at that stage where they spend a lot of the time on the floor and put things in their mouth,” said Karin English, PhD candidate at the University of Queensland. As a result of children’s propensity for hand to mouth motion, cockroach baits and ant liquid were found to be the most common source of insecticide exposure for kids under five, covering 39% of calls. However, Ms. English notes that enclosing […]

(Beyond Pesticides, August 14, 2016) According to recent reports, the illegal misuse of pesticides in Dubai has left ten people dead within the last year. The culprit? Domestic use of a pesticide containing highly toxic aluminum phosphide sold on the black market, touted as a way to fight bed bugs for low-income families that may not have the education level or means to research and pursue other options. While the government acknowledges a significant problem given the common occurrence of these  deaths, those in positions of power are admittedly at a loss when it comes to finding a solution, with some calling for a crack down on those selling the pesticides illegally, and others wanting to punish those that buy and use it. Regardless of the actions, elected officials decide to pursue, embracing organic pest management systems, as well as a robust education campaign, will be critical in curbing these deaths. Given the availability of greener, safer alternatives, Beyond Pesticides opposes any registration or allowance of phosphide fumigants and other highly toxic chemicals that can be easily misused. Phosphide fumigants, including aluminum phosphide, are known to be acutely toxic when ingested or inhaled. Symptoms of mild to moderate acute exposure […]

(Beyond Pesticides, August 12, 2016) A new study by a team of scientists at Virginia Tech finds that commonly used in-hive pesticides result in changes to the honey bee gut microbiome. The study, Honey bee gut microbiome is altered by in-hive pesticide exposures, was led by Virginia Tech associate professor of horticulture, Mark Williams, Ph.D., and colleagues from Oregon State University and North Carolina State University. This research, published several weeks ago in the journal Frontiers in Microbiology, aimed to determine the microbiome of honey bees (Apis mellifera) after being exposed to three common pesticides. Coumaphos and tau-fluvalinate, both common miticides used in conventional beekeeping, and chlorothalonil, a fungicide commonly detected in hives, were used as pesticide treatments in the study. While this  research contributes to the already established body of science on the complexity of pesticide exposure effects, beekeepers reported the steepest, and then sustained, declines in honey bee populations after the large  increase in  neonicotinoid pesticide  use in the early 2000’s. Beekeepers nationwide suffered  their highest hive losses of 44.1% in the last national survey from April 2015-2016. While it is likely that neonicotinoids are not the sole factor in pollinator decline, they have been found to exacerbate […]

(Beyond Pesticides, August 10, 2016) New research connects 78 pesticides commonly used by farmers with many adverse respiratory effects, including both allergic and non-allergic wheeze. The study, Pesticides Are Associated with Allergic and Non-Allergic Wheeze among Male Farmers, was led by NC State environmental epidemiologist, Jane Hoppin, ScD and colleagues from the National Institute of Environmental Health Sciences (NIEHS), the National Cancer Institute, Westat and the National Institute for Occupational Safety and Health (NIOSH). This is one of the most comprehensive evaluations of pesticides in relation to wheeze that has been evaluated to date, finding that several commonly used pesticides in both agriculture and residential settings can cause adverse respiratory effects. “Fifty-one of the pesticides we tested in this study had never been analyzed in terms of their effects on respiratory outcomes. And some of them, like glyphosate, 2,4-D and permethrin, aren’t just used on farms. They’re used residentially now to kill weeds or treat fleas on pets,” said Dr. Hoppin. “We believe it’s important information that will help people make decisions about pesticides.” Researchers used interview data from the 2005-2010 Agricultural Health Study (AHS) to assess the correlation between pesticide exposure and wheeze in male farmers. 22,134 farmers were […]

(Beyond Pesticides, August 10, 2016) In a letter, submitted by the Soil Association, leading bread producers and supermarkets in the United Kingdom (UK) are being urged to cease stocking and selling bread products that  contain traces of the herbicide glyphosate. Glyphosate, the active ingredient in Monsanto’s Roundup, has been classified as a probable human carcinogen by the World Health Organization (WHO) and is linked to numerous other environmental and human health concerns. Glyphosate residues have already been detected in bread, beer, and wine. The Soil Association, a UK organization that campaigns for healthy, humane and sustainable food, farming and land use, is concerned that glyphosate is used on crops immediately before harvest, and subsequently makes its way into food. According to the letter and a spokesperson for the group, “Using glyphosate, and glyphosate-based products, as a pre-harvest treatment is fundamentally wrong, and we are calling for an end to it with our campaign.  Wheat harvest will start in the next few weeks, and we are asking bread companies to act now and put a stop to glyphosate as a pre-harvest desiccant in their supply chains. The EU has just advised glyphosate use as a pre-harvest spray on food crops should […]

(Beyond Pesticides, August 9, 2016) Farmers in Missouri, Arkansas, and Tennessee are confronting widespread crop damage and bracing for lower yields as a result of agrichemical giant Monsanto’s botched roll-out of new genetically engineered soybean and cotton crops. The company, whose current line of glyphosate-tolerant crops are failing to control weeds throughout the U.S. and across the globe, developed a new line of soybean and cotton with traits that make it tolerate applications of an older herbicide dicamba. However, while its seeds are available for purchase on the market, and Monsanto is encouraging farmers to grow them, the company has yet to receive EPA regulatory approval for the dicamba herbicide meant to be used with the plants. A spate of news reports over the past two  months in southern soybean growing regions finds that many farmers are illegally applying off-label dicamba-based herbicides to Monsanto’s new GE crops in an effort to control weeds resistant to glyphosate. Use of this highly volatile herbicide is causing widespread crop damage not only to soybeans that don’t carry the resistance trait, but other crops in the region, including peaches, melons, and tomatoes. Dicamba has a strong propensity to volatilize small particles of the herbicide […]

(Beyond Pesticides, August 8, 2016) Last week, the Environmental Protection Agency (EPA) received a  letter  from Earthjustice requesting that the agency notify the Hawaii State Department of Agriculture (HDOA) of its chronic failure to meet statutory duties for pesticides regulation and enforcement under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and, if timely corrections are not made, to rescind HDOA’s primary enforcement authority completely. Earthjustice has asked EPA to immediately notify HDOA that it has failed to carry out its responsibilities, and, pursuant to FIFRA, to give the agency 90 days to correct its overwhelming shortcomings. If the problems, which include failure to enforce pesticide use violations and a large backlog of pesticide complaints and investigations dating back to as early as 2008, are not corrected and addressed within 90 days, Earthjustice requests that EPA revoke HDOA’s primary enforcement authority indefinitely.  In the event that HDOA’s authority to regulate is stripped, EPA would then take over the responsibility for enforcing pesticide use violations occurring within the state. Under FIFRA,  the federal statutory authority for  pesticide approval and use, EPA may  delegate to  a state primary responsibility for enforcing pesticide use violations if thestate has adequate pesticide laws and adequate […]

(Beyond Pesticides, August 4, 2016) Complaints about a green residue that appeared on golfers’ shoes at Rye Golf Club in New York last spring prompted an investigative report by The Journal News/lohud.com, that  revealed what reporters are describing a region-wide “environmental toxic time bomb” caused by the over and misuse of pesticides throughout the state. The investigation uncovered (i) gaps in the oversight of millions of pound of toxic pesticides applied throughout the Lower Hudson Valley, (ii) heightened health risks in Westchester and Rockland counties where pesticides are used the most, (iii) significant flaws in pesticide data collected in the state of New York, and (iv) the failure of authorities to catch the illegal sale and use of unregistered pesticides. Rye Golf Club, which turned into a “field of dustbowls” within weeks of the green residue appearing on golfer’s shoes, had to close 18 putting greens, leading members to demand thousands of dollars in refunds and city leaders to address the severely damaged city-owned golf course. The cause of the mysterious green residue was later revealed to be the result of an application of a contaminated batch of the fungicide ArmorTech ALT 70, whose active ingredient is azoxystrobin. Rye Golf […]

(Beyond Pesticides, August 3, 2016) Home pest control giant Terminix reached a tentative settlement agreement this week of $87 million with  the  Esmond family for the severe poisoning of the mother, father and two teenage children with the highly neurotoxic pesticide fumigant  methyl bromide.  The company treated  a neighboring unit  to  their vacation residence  last spring  at a  condo resort complex in St. John, U.S. Virgin Islands. This amount is in addition to $3 million already paid to the family to cover the insurance deductible, and an undisclosed amount that the company’s insurance carriers have agreed to pay pursuant to their general liability insurance policies, according to an earnings report filed by the Terminix’s parent company, ServiceMaster Global Holdings, Inc. of Memphis, Tennessee. Stephen Esmond became paralyzed after the March 2015 incident, while his two sons spent weeks in critical condition. The mother,  Theresa Devine is still recovering. Beyond Pesticides’ executive director, Jay Feldman, spoke to CBS Evening News August 2 on the poisoning. Watch news piece  here.   Methyl bromide is a restricted use pesticide and is not registered for residential use, according to the U.S. Environmental Protection Agency’s (EPA) 2013 Methyl Bromide Preliminary Workplan. It was taken off […]

(Beyond Pesticides, July 29, 2016)  A study released earlier this week finds lower IQ (intelligence quotient) in children born to mothers who during their pregnancy were living in close proximity to chemical-intensive agricultural lands where organophosphate pesticides were used. This study adds to the body of scientific literature that links prenatal exposure to organophosphate pesticides with lower IQ’s in children. Organophosphate pesticides, a relatively older generation of highly neurotoxic pesticides still widely used on farms in California, have been associated with a  broad range of diseases  in both children and adults.  This  latest study  supports health and environmental advocates’ call to eliminate these toxic pesticides in agriculture and move toward safer, sustainable, and organic management practices. The study, titled  Prenatal Residential Proximity to Agricultural Pesticide Use and IQ in 7-Year-Old Children, looks at 283 women and children from the agricultural Salinas Valley who are enrolled in the long-term Center for the Health of Mothers and Children in Salinas (CHAMACOS) study. Specifically, researchers looked at pregnant women living within one kilometer of agricultural fields where organophosphate pesticides were used. They found that at age 7, the children of those women had declines of approximately two IQ points and three verbal reasoning […]

(Beyond Pesticides, July 28, 2016)   Led by the Institute of Bee Health at the University of Bern, new research finds evidence that two commonly used neonicotinoid (neonic) insecticides have a significant adverse effect on the reproductive ability of male honey bees (drones) and queen bees in managed and wild colonies. The study,  Neonicotinoid insecticides can serve as inadvertent insect contraceptives, published in  Royal Society Journal Proceedings B, focuses on the differences in lifespan and viability of sperm throughout exposed and unexposed drones. Since 2006, honey bees and other pollinators in the U.S. and throughout the world have incurred ongoing and rapid population declines from hive abandonment and bee die-off in a phenomenon known as colony collapse disorder (CCD).  Neonicotinoids, such as imidacloprid, thiamethoxam and clothianidin, have been found by  a growing body of scientific literature  to be linked to the CCD phenomenon and  pollinator decline in general. While science has become increasingly clear that these  pesticides  play a critical role in contributing to  the ongoing decline of bee health, this is one of the first to look at how these chemicals specifically effect the fertility of male honeybees. In the study, scientists randomly assigned honeybee colonies consisting of drones […]

(Beyond Pesticides, July 27, 2016) In South America, Colombia has officially declared an end to its Zika epidemic. The country, which previously had the highest cases of suspected Zika virus infection after Brazil, with a total of more than 99,721 people infected since September 2015 have registered a drop in the number of infections to 600 new cases a week, down significantly from a peak of more than 6,000 cases a week in February, according to health officials. Fernando Ruíz, M.D., Deputy Minister of Health and Service Provision in Colombia, said the numbers signaled that the epidemic had given way to an endemic phase of the disease, in which it continues to be present but spreads much more slowly. This news arrives following the publication of Zika Virus Disease in Colombia —Preliminary Report, which suggests that infe ctions late in pregnancy may pose less risk to the fetus than widely feared. The report follows thousands of women in Colombia who have had symptoms consistent with Zika virus disease during pregnancy to try to better understand the risk the virus poses. At the time of the report, the country had only seven official cases of microcephaly, a birth defect marked by […]

(Beyond Pesticides, July 26, 2016)  Health Canada’s Pest Management Regulatory Agency (PMRA) announced this week it will cancel certain  formulations  of boric acid-based pesticides. The announcement reflects the latest science showing that certain products, such as those in dust formulations or open baits, put residents at inhalation and ingestion exposure risk, respectively, to the naturally occurring element  boron and borate compounds. PRMA’s decision  is part of the Health Canada’s registration review of boric acid, which, like that of the U.S. Environmental Protection Agency (EPA), is conducted every 15 years. PRMA is cancelling the following uses of boric acid and similar compounds All domestic dust formulation products All domestic granular formulation products Domestic solution formulation products, with the exception of enclosed bait stations and spot treatment with gel formulations For other uses, PRMA has amended label requirements to better protect handlers and users of the pesticide. For example, the agency will update label directions to specify that boron products can only be applied to areas inaccessible to children and pets. Jane Philpott, Minister of Health in Canada said in a press release, “even natural ingredients like boric acid can pose a risk to Canadians. That’s why Health Canada looks at all […]

(Beyond Pesticides July 25, 2016) The Oregon Department of Agriculture (ODA) last week issued 12 notices of statewide detainment and stop sale and removal orders for horticultural pesticide products that contain active ingredients not listed on the label. The orders call for the product manufacturers to immediately cease all sales, offers of sale, or other distribution in Oregon. This is the latest effort by a state with a legalized marijuana market to try to  curb the use of illegal pesticides in cannabis production, a practice that poses potential health threats to consumers, creating a regulatory challenge for state officials in states that have legalized marijuana for medicinal and or recreational purposes. Because the U.S. government classifies cannabis as a narcotic, the U.S. Environmental Protection (EPA) does not register pesticide products for use in its production, leaving consumers exposed to hazardous pesticides through inhalation, ingestion, and dermal absorption without any evaluation of potential health effects. The products in question are commonly used in horticulture and hydroponics, including cannabis production. The 12 notices cover 14 products sold in Oregon that were also identified by the Washington State Department of Agriculture (WSDA) in late June as containing undeclared pesticide active ingredients. In an […]

(Beyond Pesticides, July 22, 2016) This week, Walmart released the names of eight chemicals, including one pesticide,  classified as High Priority Chemicals (HPCs), which it has asked suppliers to remove from their products. The HPCs are a subset of Walmart’s list of Priority Chemicals (PCs), which is compiled from chemicals identified as hazardous by a number of state, national, and international authorities. In 2013, Walmart released a Sustainable Chemistry Policy and pledged to increase transparency of product ingredients, advance safer formulations of products, and to attain U.S. Environmental Protection Agency (EPA)’s Safer Choice certification for Walmart’s own private brand products. After three years, Walmart has not hit the mark on many of its stated goals. The transparency provision of the Sustainable Chemistry Policy requires all suppliers to provide full online ingredient disclosure beginning January 2015 and Walmart Priority Chemicals on packaging beginning January 2018. Walmart says that 78% of suppliers responding reported disclosure for all products. For their goal of advancing safer formulations of products, Walmart focused on reducing the HPCs. Importantly, seven of the eight high priority chemicals are undisclosed so-called “inert” ingredients in pesticide products, which should be disclosed under the policy. However, the disclosure occurs through the […]

(Beyond Pesticides, July 21, 2016) An investigative report released yesterday by Center for Biological Diversity (CBD) concludes  that, over the past six years, the U.S. Environmental Protection Agency (EPA) has approved nearly 100 pesticide products with chemical mixtures that elevate the formulations’  toxicity, but are not specifically evaluated  by the agency. CBD finds that these formulations add  more stress to already-jeopardized pollinators and rare plants. The report Toxic Concoctions: How the EPA Ignores the Dangers of Pesticide Cocktails, highlights a long-running blind spot within EPA’s pesticide evaluation program, which Beyond Pesticides has long sounded the alarm on: the risk associated with combining mixtures of different pesticide active ingredients, which independent science shows may be more toxic than a single active ingredient by itself, also known as pesticide synergism. The mixtures occur as a result of multiple ingredients in individual products or  because of exposure to multiple pesticide product residues in food, air, water, and land areas, such as lawns, playing fields, and parks. “It’s alarming to see just how common it’s been for the EPA to ignore how these chemical mixtures might endanger the health of our environment,” said Nathan Donley, Ph.D., a scientist with the CBD, and author of […]

(Beyond Pesticides, July 20, 2016) Farmers and land managers across the U.S. are being encouraged to plant pollinator habitat adjacent to farmlands to provide shelter and food for pollinator species. But according to a new study published last week, these conservation areas still put bees at risk for pesticide contamination, as they fail to provide spatial or temporal relief. This study emphasizes that meaningful solutions to reversing pollinator decline does not lie with focusing on planting pollinator habitat, but ensuring that these refuge areas are free from pesticide contamination, highly toxic to bees and other pollinators, and reducing the reliance on toxic chemical inputs in agriculture and other landscapes. The study, “Neonicotinoid-contaminated pollinator strips adjacent to cropland reduce honey bee nutritional status,” finds that pollinator habitat adjacent to agricultural areas not only becomes a source for pesticide, especially neonicotinoid, exposures, but also poses significant risk to honey bees. The authors, Christina Mogren, PhD, and former USDA entomologist, Jonathan Lundgren, PhD, initially sought to study whether increasing forage by planting pollinator habitat in an agricultural-dominated region would serve to buffer against the harmful effects of plant-incorporated pesticides. However, the authors note that it soon became apparent that the unintended consequence was […]

(Beyond Pesticides, July 19, 2016) Exposure to common pesticides at levels often found in the environment can have subtle but significant impacts on the behavioral health of fish, amphibians and other aquatic invertebrates. According to researchers at Northern Arizona University, who analyzed data from nearly 40 experiments to reach their conclusion, fish and amphibians swam 35% slower and were 72% less active after pesticide exposure. Chemical Class Type Example Pesticides Carbamates Insecticide Carbaryl, Aldicarb Organochlorine Insecticide DDT, Endosulfan, Chlordane Organophosphates Insecticide Diazinon, Chlorpyrifos Organotins Biocide Tributyltin Phosphonoglycines Herbicide Glyphosate, Glufosinate Pyrethroids Insecticide Permethrin, Bifenthrin, Esfenvalerate Triazines Herbicide Atrazine, Simazine The study, published in Science of the Total Environment, found that the overall effect on aquatic wildlife varied based on the chemical class the animals encountered. While pyrethroids, carbamates, and organophosphates resulted in a significant decrease in swim speed, triazines and phosphonoglycines showed no overall effect. Pyrethroids, carbamates, organophosphates, organochlorines, and organotins decreased activity, while phosphonoglycines had no overall effect, and triazines actually increased activity. “I didn’t think that we would see [an effect] across such a wide range of pesticides so consistently, but we did,” said study co-author, Catherine Propper, PhD to KNAU, “and that leads to some concerns about […]

(Beyond Pesticides July 18, 2016) A  review of the scientific literature links  glyphosate, one of the most popular weed killers in the U.S. and the active ingredient in Roundup, to a wide range of diseases through a mechanism that modifies DNA functioning, adding a new even more troubling dimension to the herbicide’s cancer classification by the International Agency for Research on Cancer. According to the most recent review, Glyphosate pathways to modern disease V: Amino acid analogue of glycine in diverse proteins, conducted by independent scientists Anthony Samsel, Ph.D. and Stephanie Seneff, Ph.D., a scientist at Massachusetts Institute of Technology (MIT), glyphosate acts as a glycine analogue that  incorporates into peptides during protein synthesis. In this process, it alters a number of proteins that depend on conserved glycine for proper function. According to the authors, glyphosate substitution for glycine correlates with  several diseases, including diabetes, obesity, asthma, Alzheimer’s disease, amyotrophic lateral sclerosis (ALS), and Parkinson’s disease, among others. Glycine, the smallest amino acid commonly found in proteins, has unique properties that support flexibility and the ability to anchor to the plasma membrane or the cytoskeleton.  This new direct biological evidence, taken together with correlational data, make a compelling case that […]
