The 46,000% Biotech Rocket: How a No-Revenue Stock Hit $30 Billion
Regencell (NASDAQ:RGC) has pulled off one of the most surreal runs in market memory soaring over 46,000% year-to-date, catapulting from a $53 million microcap to a nearly $30 billion juggernaut. The Hong Kong-based biotech, which listed on Nasdaq in 2021, specializes in traditional Chinese medicine aimed at treating neurological disorders and COVID-19. And yet, it hasn't generated a single dollar in revenue since inception. Earlier this month, the company executed a 38-for-1 stock split a move that sent shares up 283% in one day and triggered more than 10 trading halts. The stock's tiny float and frenzied momentum may be doing more heavy lifting than anything on the balance sheet. Warning! GuruFocus has detected 2 Warning Signs with RGC. Regencell's formula is rooted in herbal compounds "no synthetic ingredients," the company says targeting conditions like ADHD and autism. It also claimed its therapy reduced COVID symptoms in six days during a 2022 trial, though the results haven't been peer-reviewed. The firm itself has acknowledged it hasn't filed for regulatory approval, holds no patents, and has no distribution channels. It ended its last fiscal year with a $4.4 million net loss and continues to fund operations largely through shareholder loans and IPO proceeds. Still, the company's narrative natural medicine meets neurological care has attracted a wave of speculative attention. Like many early-stage biotech firms, Regencell is bleeding cash but it's doing so with a surprisingly thick cushion. As shown in the chart below, the company raised a sizable cash pile from 2022 through 2024, even as its debt levels remained relatively modest. This financial buffer may be buying Regencell time to run trials and fund operations while retail traders do the rest. What's possibly fueling this rocket? Just 6% of Regencell's 500 million shares are available for trading. The rest 86% is held by insiders, mostly CEO Yat-Gai Au. That ultra-low float dynamic can turbocharge even modest demand into massive price moves. For investors, this is either a once-in-a-decade asymmetrical upside or a gravity-defying bubble waiting to reset. With no news, no revenue, and no roadmap from management, the Regencell frenzy raises more questions than answers but for now, the market can't seem to look away.

Addex to Present Positive GABAB PAM Chronic Cough Data at the 10th American Cough Conference
Geneva, Switzerland, June 5, 2025 - Addex Therapeutics (SIX/NASDAQ: ADXN), a clinical-stage biopharmaceutical company focused on developing a portfolio of novel small molecule allosteric modulators for neurological disorders, announced today that preclinical data from its gamma-aminobutyric acid sub-type B receptor (GABAB) positive allosteric modulator (PAM) cough program will be presented at the 10th American Cough Conference (June 6-7) in Dulles, VA. A presentation given by Mikhail Kalinichev, Head of Translational Science at Addex will describe the progress seen to date with the Addex GABAB PAM cough program, including antitussive data from in vivo models. Addex lead drug candidate is ready to start IND enabling studies. Details of the Presentation Date: Saturday, June 7, 2025Time: 11:20 am ESTTitle: Compound A, a novel positive allosteric modulator of the GABAB receptor, shows robust antitussive efficacy and signs of wide therapeutic margin in models of cough in guinea pigsLocation: Hyatt Regency Dulles, 2300 Dulles Corner Blvd., Herndon, VA, US, 20171 About GABAB activation and cough:The main inhibitory neurotransmitter GABA activates ionotropic (GABAA) and metabotropic (GABAB) types of receptors. GABAB receptors are widely expressed on airways and in the central and peripheral components of the cough neural circuit. Activating GABAB receptors to treat chronic cough has been clinically validated with baclofen, a selective GABAB agonist, that binds the receptor within the orthosteric GABA binding site. Baclofen is used off-label to treat chronic cough patients, but its wider use is limited due to serious side effects, short half-life and gradual loss of efficacy during chronic treatment. Targeting an allosteric site of the receptor is expected to provide many advantages, including higher selectivity, better tolerability and lack of tolerance compared to an orthosteric compound. About Addex TherapeuticsAddex is a clinical-stage biopharmaceutical company focused on developing a portfolio of novel small molecule allosteric modulators for neurological disorders. Addex's lead drug candidate, dipraglurant (mGlu5 negative allosteric modulator or NAM), is under evaluation for future development in brain injury recovery, including post-stroke and traumatic brain injury recovery. Addex's partner, Indivior, has selected a GABAB PAM drug candidate for development in substance use disorders and has successfully completed IND enabling studies. Addex is advancing an independent GABAB PAM program for chronic cough. Addex also holds a 20% equity interest in a private spin out company, Neurosterix LLC, which is advancing a portfolio of allosteric modulator programs, including M4 PAM for schizophrenia, mGlu7 NAM for mood disorders and mGlu2 NAM for mild neurocognitive disorders.

Junk Food Is Filling Our Brains With Microplastics, Raising Mental Health Risks, Scientists Warn
Scientists have found alarming amounts of microplastics in virtually everything, from sea turtles to testicles. But discovering a plastic spoon's worth of these pernicious particles inside human brains may be the most disturbing of all. That recent finding prompted researchers to dig deeper into the health consequences of plastic accumulation in the brain. According to a new review study, published today in the journal Brain Medicine, microplastics may be the missing link in the relationship between ultra-processed foods and certain neurological disorders, such as depression and dementia. 'We're seeing converging evidence that should concern us all,' said lead author Nicholas Fabiano, a psychiatry resident at the University of Ottawa, in a statement. 'Ultra-processed foods now comprise more than 50% of energy intake in countries like the United States, and these foods contain significantly higher concentrations of microplastics than whole foods,' he added. Indeed, multiple studies suggest that the more processed a food product is, the more plastic particles it is likely to contain. For example, one study found that chicken nuggets contain 30 times more microplastics per gram than chicken breasts. This may be due to the increased amount of plastic that ultra-processed foods are exposed to during processing and packaging, according to the Food Processing Forum. Other recent studies have shown that microplastics can bypass the blood-brain barrier: a protective layer of cells surrounding the brain that keeps harmful substances out and locks beneficial chemicals in. The authors of the brain-spoon study, led by Alexander Nihart, Marcus Garcia, and Eliane El Hayek of the University of New Mexico, believe that microplastics infiltrate the blood-brain barrier by hitching a ride on fat molecules. Once these particles get inside the brain, they induce oxidative stress that damages cells and increases the risk of neurological disorders, Fabiano's study states. He and his colleagues note that microplastics appear to have a particular impact on neurotransmitters that play a role in neuropsychiatric disorders such as depression and dementia. It's a big, bold claim that still needs to be verified with further research. Interestingly, these harmful effects are strikingly similar to those triggered by ultra-processed foods, according to the researchers. A previous review found that people who consumed these foods had a significantly higher risk of depression, anxiety, and poor sleep. And multiple studies have linked this type of diet to an increased risk of dementia. As a result, Fabiano and his colleagues suggest that microplastics could be a hidden driver of neurological disorders associated with ultra-processed food consumption. 'This hypothesis is particularly compelling because we see remarkable overlap in biological mechanisms,' said co-author Wolfgang Marx, senior research fellow at Deakin University in Australia, in the statement. 'Ultra-processed foods have been linked to adverse mental health through inflammation, oxidative stress, epigenetics, mitochondrial dysfunction, and disruptions to neurotransmitter systems. Microplastics appear to operate through remarkably similar pathways,' he added. So, that's the bad news. Here's the good news: a complementary study, also published in Brain Medicine today, provides the 'first evidence' to suggest that a well-established medical technique called extracorporeal apheresis could remove microplastics from the body. This procedure involves extracting a patient's blood and running it through a machine that separates it into its parts: plasma and blood cells. Then, the plasma is filtered to remove any unwanted substances (like microplastics) and the clean plasma and blood cells are put back into the patient. It's a relatively simple technique that's used all over the world for certain types of blood donation, therapeutic purposes, stem cell collection, and more. In tests with 21 patients, at least two rounds of extracorporeal apheresis with double-filtration successfully removed microplastics from their blood, according to the study. 'While we need to reduce our exposure to microplastics through better food choices and packaging alternatives, we also need research into how to remove these particles from the human body,' said lead-author Stefan Bornstein, a professor of cardiovascular and metabolic medicine at King's College London, in the statement. 'Our early findings suggest that apheresis might offer one possible pathway for microplastic removal, though much more research is needed,' he added. Thus, as the global plastic crisis becomes more troubling by the day, exploring ways to protect the body from microplastics could help us clear our minds—literally.

The foods ‘driving an autism, depression and dementia epidemic' revealed in bombshell study
FOODS that make up around 57 per cent of the average UK diet are fuelling autism, depression and dementia cases, scientists warn. In a major new review, ultra-processed foods (UPFs) have been linked to rising rates of neurological disorders. The actual culprit is believed to be microplastics, which are found in alarming levels in UPFs. UPFs are more susceptible to microplastics than other foods due to their packaging, additives and the equipment used to process them. Co-lead author of the new paper Dr Nicholas Fabiano, from the University of Ottawa, said: "We're seeing converging evidence that should concern us all. " Ultra-processed significantly higher concentrations of microplastics than whole foods. "Recent findings show these particles can cross the blood-brain barrier and accumulate in alarming quantities." Another author, Dr Wolfgang Marx from Deakin University's Food & Mood Center, said there is "remarkable overlap" in the way UPFs and microplastics harm mental health. He explained: "This hypothesis is particularly compelling because we see remarkable overlap in biological mechanisms. "Ultra-processed foods have been linked to adverse mental health through inflammation, oxidative stress, epigenetics, mitochondrial dysfunction, and disruptions to neurotransmitter systems. "Microplastics appear to operate through remarkably similar pathways." In the new article published in the May issue of Brain Medicine, researchers reviewed studies that focused on the relationship between ultra-processed foods, microplastics and mental health. 5 ultra-processed foods to avoid One study, recently published in The British Medical journal, found people who consumed UPFs had a 22 per cent high risk of depression, a 48 per cent higher risk of anxiety, and a 41 per cent higher risk of poor sleep - which can negatively impact brain health. Another study included in their review found microplastics and nanoplastics induce oxidative stress and the central nervous system, which could lead to cellular damage and raise the risk of neurological disorders. Based on current data, the authors concluded high levels of microplastic contamination in UPFs could be why they have such a detrimental impact on health. Scientists believe UPFs can negatively impact brain health by disrupting the gut-brain axis - communication between the gastrointestinal tract and the brain - promoting inflammation, and potentially leading to cognitive decline and mental health issues like depression and anxiety. Alongside brain health, UPFs have been linked to a wide range of negative health outcomes. Consuming lots of UPFs can increase the risk of developing type 2 diabetes. A recent study found substituting 10 per cent of UPFs with minimally processed foods reduced the risk of type 2 diabetes by 18 per cent. A study published last year found people who eat lots of UPFs may be at greater risk of dying early. And there's been some research that indicates a correlation between UPF intake and a higher risk of overall cancer, head and neck cancer, oesophageal adenocarcinoma, breast cancer, ovarian cancer, and brain cancer. However, more research is needed to fully understand the mechanisms behind this association and the relative impact of different dimensions of processing on cancer risk. How ultra processed is YOUR kitchen? Ultra processed foods (UPFs) were defined by Brazilian researchers who made the NOVA classification system. It breaks foods into groups depending on how processed they are. The most natural foods are in group 1, while the most processed are in group 4. The groups do not entirely indicate how healthy a food is. However, it does indicate how processed it is - and studies have linked UPFs to a number of diseases. How does your kitchen compare to the following groups? Unprocessed or minimally processed foods (group 1) vegetables and fruits (fresh or frozen) dried fruits with no added sugar, honey, or oil grains and legumes (chickpeas, lentils) meat, poultry, fish, seafood, eggs milk without added sugar plain yogurt with no added sugar nuts and seeds spices and herbs tea, coffee, water Processed culinary ingredients (group 2) iodized salt salted butter sugar and molasses from cane or beet honey extracted from combs syrup from maple trees vegetable oils crushed from olives or seeds butter and lard from milk and pork starches extracted from corn and other plants vegetable oils with added anti-oxidants vinegar with added preservatives Processed foods (group 3) canned vegetables, fruits, and legumes fruits in syrup salted or sugared nuts and seeds salted cured or smoked meats canned fish artisanal breads and cheese Ultra-processed foods (group 4) pop and fruit drinks sweetened yogurt sweet or savoury packaged snacks (e.g., cookies) candies and cake mixes mass-produced packaged breads and buns margarines and spreads breakfast cereals cereal and energy bars energy drinks instant soups, sauces, and noodles poultry and fish nuggets, hot dogs many ready-to-heat products: pre-prepared pies, pasta, and pizza dishes

Scientists discover toxic substance hiding in 100% of people's brains... and 'it explains rise of dementia in US'
Scientists have made a startling study in the human brain that could be fueling the rise of dementia in the US They analyzed brain tissue from 54 autopsies, discovering that every sample contained microplastics, equivalent in mass to an entire plastic spoon. Microplastics are small plastic pieces that are less than 5mm in size and insoluble in water. They are harmful for environment and lead to plastic pollution. These tiny particles can accumulate in the body, with prior research linking them to various forms of cancer—including skin, breast, cervical, and colorectal—as well as testicular cancer, Alzheimer's disease, and dementia. The researchers found that individuals diagnosed with dementia exhibited up to ten times more microplastics in their brain tissue compared to those without this condition. Although the study does not directly connect them, it does show a relationship between the accumulation of microplastics and neurological disorders. Lead author Professor Matthew Campen of the University of New Mexico emphasized the urgency of understanding how these particles penetrate the brain's protective barriers—and what damage they may cause over time. 'I never would have imagined it was this high,' he said. Professor Campen, a toxicologist, said microplastic levels in the human brain have increased by 50 percent over the past eight years, mirroring the global rise in plastic pollution. To investigate this trend, Campen's team analyzed brain tissue samples provided by the New Mexico Office of the Medical Investigator, which is legally required to retain autopsy tissue for seven years before disposal. The samples were taken during autopsies in 2016 and 2024. All samples were taken from the frontal cortex—the brain region located above and behind the eyes, Campen noted. To isolate microplastics, the tissues were dissolved using a specialized chemical process that left behind a pellet of undissolved material. This pellet was then heated, allowing researchers to capture the gas emissions released as the plastics burned. Using this technique, the team detected and measured 12 different plastic polymers. The most common was polyethylene, a material widely used in packaging and containers such as bottles and cups. On average, the brain tissue contained about 4,800 micrograms of microplastic per gram —roughly equivalent to the weight of a plastic spoon. Researchers also discovered clusters of sharp plastic shards measuring 200 nanometers or smaller—not much larger than some viruses. Microplastics—especially nanoplastics—can cross the blood-brain barrier, a protective shield that typically prevents harmful substances from entering the brain. Once inside, these tiny particles may trigger inflammation, disrupt neurological signaling, and potentially contribute to the development of neurological disorders. While scientists are still investigating the direct impact of microplastics on human health, animal studies have shown that exposure can lead to behavioral changes, memory impairment, and reduced motor coordination. Dr Gary Small, chair of psychiatry at Hackensack University Medical Center, emphasized that current findings in relation to dementia do not prove a causal relationship, but they are still cause for concern. The most common plastics identified in brain samples were polyethylene and polypropylene, materials widely used in packaging, containers, and everyday consumer goods. These particles most likely enter the body through contaminated food and beverages. According to Professor Campen, the research team even found significant levels of microplastics in store-bought meat. To that he added, 'The way we irrigate fields with plastic-contaminated water, we postulate that the plastics build up there.' Over time, chemicals may accumulate in fields as a result of the feeding of crops to livestock and the fertilization of fields with their waste. A study conducted by the Ocean Conservancy found that highly processed protein products—such as fish sticks, chicken nuggets, and plant-based burgers—contained significantly more microplastics per gram than minimally processed alternatives. In response, health professionals recommend several strategies to reduce microplastic exposure. These include using glass or stainless steel containers instead of single-use plastics, installing water purifiers, and choosing natural fibers over synthetic fabrics. The study's findings have sparked growing calls for urgent action to limit microplastic exposure. Advocates are also pushing for stricter regulations on plastic production and waste management to curb environmental pollution at its source. The detection of microplastics in every human brain sample analyzed underscores the widespread reach of plastic pollution—and its potential implications for human health. As scientists continue to investigate the long-term effects of microplastic exposure, experts stress the importance of taking preventive steps now to reduce risk and safeguard public health.
