Marine mammals in California getting sick from algae: Care center
(NewsNation) — The number of current marine animals that are likely affected by toxic algae bloom has gone up noticeably, one California care center said last week.
'Over the last week, the number of current MMCC patients likely impacted by the toxic algal bloom has more than tripled,' the Marine Mammal Care Center said last Wednesday on Instagram.
Marine Mammal Care Center said it does not know how long the domoic acid outbreak will last, but if it continues to bring in 3 to 5 animals per day, 'these numbers will add up quickly.'
The organization, based in San Pedro, California, warned that because it is also the time of year when starving young elephant seal pups start to strand along the Los Angeles County Coastline, the MMCC's hospital could see capacity issues.
Brain's immune system could treat Alzheimer's: Study
In 2023, the Marine Mammal Care Center had 70 sea lions in its care by July, KNBC reported. Now, the center is already half full. John Warner, CEO of the Marine Mammal Care Center, said in an interview with KNBC that they have room for about 120 animals and are now at more than 50.
'While we are concerned about the long-term health of marine mammals and the ocean environment due to the toxic chemical runoff from the recent fires, we believe the current situation on our coast is due solely to domoic acid toxicosis (DA) and the confirmed prevalence of Pseudo-nitzschia australis (the type of algae that produces DA) along the Southern California Coast,' the Marine Mammal Care Center said.
Domoic acid, according to the center, is a neurotoxin that accumulates in small fish, which are eaten by marine mammals. Eating the toxin attacks the brain and heart, which can cause seizures, heart failure and, if left untreated, permanent brain damage.
Clarissa Anderson, a biological oceanographer at the Scripps Institution of Oceanography, told The Guardian that scientists have seen a 'steep change' in how intense toxic algae blooms are and how long they last.
'In the last four years, the impacts have been really heavy on the marine mammal side, both sea lions, some fur seals, and quite a few long-beaked common dolphins,' Anderson said.
However, heavy rains and nitrate-rich organic runoff do feed these algae blooms and can contribute to their size and severity. These acidic blooms used to occur every 4 to 7 years. The frequency of these blooms has increased in recent years, exacerbated by climate change, warming ocean temperatures and other human activities.
If people see a stranded animal, they can report it to the Marine Mammal Care Center by calling 1-800-39-WHALE.

10 foods that may reduce your risk of developing dementia
Dementia is the health condition that almost half of us fear the most. So it stands to reason that we're constantly looking for ways to avoid developing it. Alongside making lifestyle changes, there are other steps you can take that may lower your risk. Including, tweaking your diet. According to a new study, people aged 45 to 75 who followed the MIND diet (more on that in a moment) were less likely to develop Alzheimer's and other forms of dementia. The research, conducted by the University of Hawaii at Manoa, found that the closer people stuck to the diet, the more their risk dropped. Even small improvements to diet over time were linked to an average 9% drop in dementia risk. And people who improved their adherence to the diet over 10 years – including those who didn't follow it closely at first – had a 25% lower risk of dementia than those whose adherence dropped. "Our findings confirm that healthy diet patterns in mid to late life and their improvement over time may prevent Alzheimer's and related dementias," said Dr Song-Yi Park, associate professor at the University of Hawaii at Manoa. If you've heard of the Mediterranean diet or DASH diet before, you're already halfway there. MIND stands for Mediterranean-DASH Intervention for Neurodegenerative Delay. A bit of a mouthful, yes, but it's really just a blend of two diets already linked to better heart and brain health. It's not about counting calories but building habits over time and cutting back on things that aren't as brain-friendly: processed snacks, sugary drinks and alcohol. The focus is on everyday brain foods – including leafy greens, berries, nuts, and olive oil – that scientists say can help protect brain cells, improve memory, and reduce inflammation. According to Alzheimer's Research UK, this way of eating has been linked to a range of health benefits, including improved brain health. So, if you're wondering what to actually eat, here are the key foods to focus on, plus easy ways to get more of them in your five-a-day. Eating your greens might be one of the simplest ways to support your brain health. Studies have found that eating one or two servings of leafy greens daily, such as spinach, kale, and Brussels sprouts, can slow down age-related cognitive decline. In fact, older adults who regularly included these vegetables in their diet performed on memory tests as if they were 11 years younger than those who ate them less frequently. Tips for eating more: Add spinach or kale to smoothies, wilt and stir into soups or omelettes, or enjoy in a fresh salad – the MIND diet recommends aiming for at least six servings a week. Research shows that fruits and vegetables rich in carotenoids (the pigments behind those bright orange, red and yellow colours) could be linked to better brain health. That includes things like carrots, sweet potatoes, squash, red peppers, tomatoes, papaya and apricots, as well as greens like spinach and kale. Tips for eating more: Add roasted veg to grain bowls, use them to bulk out chillis, curries and ragus, or keep chopped peppers on hand for easy snacking. A variety of veg daily is the goal. Blueberries, blackberries and raspberries are packed with antioxidants and flavonoids (natural plant chemicals found in many fruits, vegetables and spices) that may help protect brain cells from damage. They've also got the bonus of being naturally lower in sugar than many other fruits. Tips for eating more: Throw them into porridge, sprinkle on pancakes, mix with yoghurt or blend into a smoothie. Try to include them at least twice a week. Fatty fish like salmon, tuna and sardines are some of the best sources of omega-3 fats, especially one called DHA – a type of fat that plays a key role in keeping the brain healthy. Our bodies can't make it on their own, so getting enough through food really matters. Tips for eating more: Bake salmon for dinner, rustle up a tuna panini, or top toast with sardines, lemon and herbs. One or more servings a week are recommended; just skip the frying, as this can increase the fat content. Walnuts, almonds, lentils, flax seeds and soybeans are small but mighty. They're rich in healthy fats, vitamin E, B vitamins, choline, magnesium and zinc, all nutrients known to support long-term brain health. Tips for eating more: Snack on a small handful, stir lentils into stews or sprinkle seeds onto yoghurt or porridge – five servings a week is MIND's recommendation. Wholegrains like oats, brown rice, quinoa and barley are high in fibre and B vitamins, and may help reduce inflammation in the brain. They also help keep your energy and focus steady – a win for memory and concentration. Tips for eating more: Start your day with porridge or overnight oats, and switch to wholemeal versions of rice, pasta and bread. Aim for three servings a day. Olive oil is one of the key ingredients in the MIND diet, and for good reason. It's high in healthy monounsaturated fats and antioxidants, and research has linked it to better brain health and a lower risk of dementia-related death. Tips for eating more: Use it for roasting veg, drizzling on salads or as a base for homemade dressings – ideally as your main added fat. Beans are an underrated brain food. They're full of fibre, plant protein and nutrients like folate, which some UK research has linked to a reduced risk of cognitive decline. They also help keep blood sugar steady, which is important for long-term brain health. Tips for eating more: Add to soups, stews or salads, or mash into dips and spreads. Aim for four or more bean-based meals a week. Lean meats such as chicken and turkey provide protein without red meat's high saturated fat content – something the MIND diet recommends limiting. Eating poultry a couple of times a week has been linked to a lower risk of memory loss later in life. Tips for eating more: Grill chicken in wraps or cook turkey mince in your usual pasta sauce. The MIND diet recommends two servings a week. Okay, it's not officially part of the MIND diet, but we all deserve a treat! Studies say a small amount of dark chocolate may offer brain benefits, especially varieties with at least 70% cocoa. Tips for eating more: Enjoy a square or two, ideally paired with nuts to slow sugar release. Or mix it into your porridge for a morning sugar bump.

RFK Jr. wants to allow more experimental therapies, acknowledging health risks and threat of ‘charlatans'
'And of course you're going to get a lot of charlatans, and you're going to get people who have bad results,' he added. 'And ultimately, you can't prevent that either way. Leaving the whole thing in the hands of pharma is not working for us.' Advertisement Kennedy cited his own experience at a clinic in Antigua, where he said he received a stem cell treatment that 'enormously' eased his neurological condition, spasmodic dysphonia, which affects his voice and has few treatment options. Get Starting Point A guide through the most important stories of the morning, delivered Monday through Friday. Enter Email Sign Up If Kennedy does permit broader use of unauthorized or experimental therapies, he would be reversing long-standing efforts by the FDA to monitor and sometimes police the emerging field. Experts, including some who support alternative medicine, worry that without safeguards, an expansion of such treatments could undermine legitimate development of new therapies. The FDA now narrowly permits stem cell therapies to treat blood and immune disorders. Nearly a decade ago, the field was so loosely regulated that the agency pursued court actions to shut down rogue clinics using unauthorized treatments for a wide array of ailments. Some providers in the United States and in other countries continue to offer experimental stem cell therapies for everything from autism to Alzheimer's to erectile dysfunction. Advertisement The latest move reflects an expansion of Kennedy's drive to dismantle federal health policy to reflect his long-held views, which had so far focused mainly on vaccines, chronic diseases, food dyes and fluoride. A push to open up the field of unregulated stem cell infusions meshes with his oft-stated contention that the FDA is a 'sock puppet' for major drug companies and faces a crisis of distrust. Wellness industry products, he has claimed, are unfairly sidelined. A spokesperson for the Department of Health and Human Services did not respond to requests for comment. Kennedy's statements alarmed experts on the field of sometimes dangerous stem cell infusions -- who noted that many of Kennedy's allies endorse wellness products ranging from red-light therapy to magnetism. 'It's a complete abdication of protection of the public, letting these grifters go forward,' said Timothy Caulfield, a research chair in health law and policy at the University of Alberta in Canada. 'For him to say, 'There are problems with Big Pharma, so we want our opportunity to be bad actors too,' it doesn't make any sense.' One leading expert group, the International Society for Stem Cell Research, reviewed Kennedy's podcast statements and condemned the approach as potentially allowing products that are 'sometimes contaminated with pathogens and are often marketed with scientifically implausible claims.' 'It is critical that the FDA maintain its regulatory authority to protect Americans from these potentially harmful and deceptive products,' the society said in a statement. Advertisement On Thursday, a panelist appearing at an FDA meeting on cell and gene therapies raised a concern about 'snake oil' treatments. Dr. Vinay Prasad, the agency's director of the center for biologics evaluation research, responded, 'We have to regulate the bad actors. We can't let that taint what we do here at the FDA.' Kennedy, who also attended the event, voiced full support for the researchers and biotech executives working on gene therapies for rare diseases, including those who made history by creating a custom gene therapy for an infant named KJ. 'We're going to do everything in our power to sweep away the barriers from you getting those solutions to market and getting them funded, and do everything that we can to support you all,' Kennedy said. On Brecka's podcast in May, Kennedy cited other products that he'd like to see more of, including chelation treatment, which was discussed in a 2015 book edited by him that focused on widely debunked theories about mercury in vaccines and autism and cites 'evidence of chelation's benefits' from a few small studies. One 5-year-old Pennsylvania boy died in 2005 from cardiac arrest after a doctor tried to treat his autism with chelation. Neither Kennedy nor the FDA has released a formal plan to change agency standards for stem cell treatments, which have typically been reviewed by the agency as individual therapies to treat a specific disease. Widening overall access could also happen informally if the agency decided to relax enforcement, an approach the FDA used in the past to indicate that it wouldn't crack down on unauthorized products. During the pandemic, for example, the agency allowed providers to retrofit infusion pumps and ventilators to treat hordes of sick patients. Advertisement During the first Trump administration, the agency's commissioner, Dr. Scott Gottlieb, escalated enforcement against stem cell providers whom he described in 2017 as 'unscrupulous actors who have seized on the clinical promise of regenerative medicine.' The FDA followed through with lawsuits seeking to stop some stem cell providers, including one case that the government won on appeal in the fall. In that case, the agency alleged that one provider, the California Stem Cell Treatment Center, was offering a drug without FDA approval by taking stem cells from a person's fat, manipulating them and infusing them as a remedy for Alzheimer's disease, cancer and arthritis. The agency classifies stem cell treatments as a 'biologic' and approves them much like a drug after careful studies of safety and effectiveness. But the FDA does make exceptions: It does not regulate some treatments if providers say they are extracting and then reinserting a person's cells with minimal manipulation. In March, Kennedy convened a meeting with leaders in the stem cell field. Two people who attended said the gathering was a fact-finding effort to explore a safe way to increase access. To Dr. Noah Raizman, who attended the meeting on behalf of the American Academy of Orthopaedic Surgeons, Kennedy's new pronouncement 'sounds a little more casual and a little bit more emboldened.' In the podcast, Kennedy said that consumers should be able to navigate the industry's claims. 'We don't want to have the Wild West,' Kennedy said. 'We want to make sure that information is out there. But we also want to respect the intelligence of the American people -- the capacity of people who explore the outcomes that are going to benefit them the most.' Advertisement In recent years, stem cell treatments have caused harm in the United States and abroad. Experts at the Pew Research Center tallied more than 350 cases of side effects including life-threatening blood infections, heart attacks and tumors. One Boston neurosurgeon discovered a huge mass of bloody tissue in the lower spine of a man who had received unproven stem cell treatments in Mexico, China and Argentina. Three patients were blinded after stem cell treatments at a Florida clinic. The FDA prevailed in getting a court order to stop the clinic from operating. The field of stem cell treatments is so complex that the Harvard Medical School created a free course to help doctors navigate patient questions, said Insoo Hyun, the director of life sciences at the Museum of Science in Boston. More than 110 stem cell clinical studies are advancing under regulatory oversight. In one, scientists at the National Institutes of Health are using retinal cells developed from patients' blood to try to treat vision loss in older adults -- and follow them for 15 years. In another study aimed at helping patients with Parkinson's disease, researchers at a biotech company in California are exploring the safety of infusing dopamine-producing neurons in a region of the brain that controls the body's movements. A Chinese company is studying a treatment for heart failure that involves transplanting cardiac muscle cells into the heart. Some providers sidestep the costly, yearslong process of careful work that can lead to an FDA approval. Among them is Dr. Chadwick Prodromos, a Chicago doctor who offers stem cell treatments in Antigua. Kennedy welcomed him warmly at the March meeting, Raizman recalled. Reached for comment, Prodromos' office said that he was in Antigua doing treatments and was not available. Advertisement In an April interview on YouTube, Prodromos said that he was still in touch with the FDA about stem cell treatments that could help people 'without allowing scams and things that aren't valid. And you know, it's a tricky proposition.' A website for Prodromos' clinic says that he and colleagues offer injections in Antigua into the joints, back, neck, scalp, penis and pelvic floor for an array of conditions including autism, thinning hair and lupus. He uses AlloRX cells, which are derived from the umbilical cord, in a manner that in the United States would require an FDA-cleared clinical trial. People can seek out unregulated treatments using their own cells that are processed, purified and amplified in different ways. They can also find treatments using others' cells that vary widely in quality and sterility. Some low-quality clinics process cells in a back room, which is the opposite of a clinical-grade cell processing site. Hyun said he recently toured one in the Netherlands that used specialized air filtering, layers of gowns and a ban on bacteria-laden cellphones in their sterile area. 'It's kind of like you're entering a space station,' he said. Ultimately, Caulfield said, many unauthorized stem cell providers adopt the language of biotech and regenerative medicine, post glowing patient testimonials and exploit patients who are desperate for a cure.

It's official: Your diet is making you depressed, according to science
Skipping dessert really can leave you down in the dumps. No one who's been on a diet has ever said, 'I love calorie restriction,' but a new study has found a not-so-surprising link between low-cal eating and depression. And some people have it worse than others. 3 Researchers found that men and those whose BMI classified them as overweight were particularly susceptible to diet-linked depression. Studio Romantic – The dietary habits and depressive symptoms of 28,000 US adults were analyzed for the study, published in BMJ Nutrition Prevention & Health. Of these adults, 29% had a healthy weight, 33% were deemed overweight, and 38% were considered obese. The dietary patterns were divided into four categories: calorie-restrictive, nutrient-restrictive (AKA low in fat), sugar, salt, or carbs, established dietary pattern, or not on a diet at all. The majority of participants, 87%, did not follow any specific diet, 8% followed a calorie-restrictive diet, 3% opted for nutrient restriction, and 2% followed an established dietary pattern. Using questionnaires from the US National Health and Nutrition Examination Survey, researchers found that 8% of participants reported depressive symptoms. Those on calorie or nutrient-restrictive diets exhibited higher scores of emotional and physical distress than their cohorts who were not on a specific diet, suggesting that unsupervised restrictive diets may negatively affect mental health. Researchers found that men and those whose BMI classified them as overweight were particularly susceptible to diet-linked depression. 3 Besides affecting your quality of life and relationships, depression can raise the risk of heart disease, diabetes, stroke, dementia, Alzheimer's disease, anxiety disorders, and substance abuse. bravissimos – 'The findings suggest caution with overly restrictive or unbalanced diets, particularly for people already experiencing weight-related stress or challenges,' said lead study author Dr. Venkat Bhat, psychiatrist, clinician-researcher, and director of the Interventional Psychiatry Program at St. Michael's Hospital and University of Toronto. Researchers found that the quality of diet had a direct bearing on depression risk. Those whose diet was rife with ultra-processed foods (UPFs) were more likely to report higher levels of depression. Recent research revealed that 60% of Americans' daily caloric intake comes from ultra-processed foods. UPFs often contain high levels of sodium, refined sugars, cholesterol-spiking fats and other lab-based ingredients. A 2023 study from the Harvard T.H. Chan School of Public Health found that people who consume nine or more servings of UPFs a day have a 50% higher risk of developing depression than those who eat four or fewer daily servings. 3 Previous studies have established that a Mediterranean diet rich in fruit, veggies, nuts, fish, and plants can slash depression risk by a third. Eightshot Images – In contrast, this latest study revealed that those who followed a Mediterranean diet exhibited lower rates of depression. Previous studies have established that a Mediterranean diet rich in fruit, veggies, nuts, fish, and plants can slash depression risk by a third. In a 2023 Gallup poll, 29% of US adults reported having been diagnosed with depression at some point in their lifetime, while 17.8% of Americans said they have depression or are being treated for it. Besides affecting your quality of life and relationships, depression can raise the risk of heart disease, diabetes, stroke, dementia, Alzheimer's disease, anxiety disorders and substance abuse. Given the results of this study, Bhat suggests dieters abstain from strict caloric restriction and instead opt for,' balanced, sustainable dietary changes that meet nutritional needs.' Researchers note that their findings only reveal associations, not definitive data. Further, due to the survey format, there's no way to verify that participants truly adhere to caloric restriction. Still, Bhat and his team are hopeful that future studies will continue to examine the relationship between calorie restriction and mental health.
