First up, our lead story is a literal "leap" forward in medicine. Scientists in Japan have discovered that a bacterium found in the gut of a Japanese tree frog can completely destroy colon cancer. The microbe, called Ewingella americana, was tested in mice with human colon cancer tumors. The results were staggering: the bacterium achieved a 100% survival and response rate, quickly and completely eradicating the tumors. After the bacterium destroyed the cancer, the mice developed long-lasting immunity against the disease. It works by secreting toxins that poke holes in cancer cells while simultaneously "recruiting" the body’s own immune system to join the fight. While still in the mouse-model stage, researchers believe this could lead to powerful new therapies for metastatic cancers in humans.

Moving on to a medical miracle that sounds like science fiction. In a world-first, surgeons in China saved a woman’s severed ear by grafting it onto her foot.

The patient, identified as Sun, lost her ear and large portions of her scalp in a devastating industrial accident. Because of extensive vascular damage, the ear couldn’t be reattached to her head immediately. Instead, a microsurgery team grafted the ear to her foot—where the blood vessels are a similar size—to keep it alive while her other injuries healed. After five months of "living" on her foot, the ear was successfully reattached to her head in a six-hour surgery. Sun has since been discharged, and her facial structure has largely recovered. It’s a testament to the idea that no matter how small the chance, medical perseverance can save lives.

Next, let’s talk about a breakthrough in mental health.

Researchers at Stanford Medicine have identified a new category of depression called the "cognitive biotype," which affects about 27% of patients. This is a game-changer because this specific biotype doesn't respond well to standard, commonly prescribed antidepressants like Zoloft or Lexapro. Patients with this biotype often struggle with "cognitive slowness," sleep issues, and difficulty with self-control. By using brain imaging and objective cognitive tests, doctors can now move away from a "trial-and-error" process and provide individualised care that targets specific brain circuits.

Finally, for our featured stories, we have a message of hope for those affected by Alzheimer’s. For over a century, the disease has been considered irreversible, but new research is challenging that dogma.Scientists have found that a decline in a central energy molecule called NAD+ is a major driver of the disease. In a landmark study, researchers used a new pharmacological agent to restore NAD+ balance in mice with advanced Alzheimer’s. Remarkably, the treatment allowed the brain to repair itself, reversing memory loss and cognitive impairment. This suggests that the damage from Alzheimer’s may not be permanent, and that restoring brain energy balance could be the key to recovery.

All right, let’s dive into the Speed Round for even more great news!•

• New York has passed a law requiring "addictive feed" warning labels for teens, treating platforms with infinite scrolling and auto-play similarly to tobacco products to protect youth mental health.
• Scientists in Sweden can now print electrodes directly onto human skin using nothing more than visible light from simple LED lamps, paved the way for safer, wearable medical sensors.•
• Researchers in Japan have doubled the efficiency of solar hydrogen production by using the metal osmium to capture a wider range of the sun's waves than ever before
• A scientific "mismatch" between computer models and lab results led to a breakthrough in carbon capture technology. By discovering that hidden water was blocking the process, scientists developed a new water-repellent material that captures CO2 more effectively.

That’s it for today’s episode of Great News.

Tired of all the doom and gloom news from mainstream media? You’ll get none of that here. Instead, you’ll find inspiring stories and developments making the world a better place.

Today we’re diving into some truly groundbreaking advancements in medicine, technology, and the natural world.

Researchers at the University of Florida have developed a new mRNA cancer vaccine that has successfully wiped out multiple types of tumours in mice, including skin, bone, and brain cancers.

Moving on to the skies, where drones are becoming the newest first responders. A study from the University of Warwick has successfully tested a system where drones deliver Automated External Defibrillators, or AEDs, directly to the scene of a cardiac arrest. In the UK, fewer than 10 per cent of people survive out-of-hospital cardiac arrests, but using an AED can at least double those odds. These drones can fly long distances to reach remote or rural areas far faster than a traditional ambulance could navigate the terrain. Researchers found the technology is ready for real-world use, meaning your next life-saver might just arrive by air. Now, let’s look at the very walls around us. Scientists at Aarhus University have created the world's first "living cement" that can store electricity. By embedding a specific bacterium called Shewanella oneidensis into the concrete, they’ve turned the most common building material on Earth into a supercapacitor. These microbes create a network that stores and releases energy, and if the power starts to fade, you can simply "feed" the bacteria nutrients to restore up to 80% of its capacity. Imagine a future where your home’s foundation stores the solar energy collected during the day to power your lights at night. Finally, a breakthrough in early detection. A new liquid biopsy test called HPV-DeepSeek can identify head and neck cancers caused by HPV up to 10 years before any symptoms appear. Developed by researchers at Harvard Medical School and Mass General Brigham, the test uses machine learning to find tiny fragments of viral DNA circulating in the blood. It reached an incredible 96% sensitivity rate in trials. Detecting these cancers early means patients can avoid the aggressive, life-altering treatments often required when tumours are found at a later stage.[Speed Round] All right, let’s dive into the speed round for even more great news:• Lasting Health from Gut Bacteria: A study from the University of Auckland found that a single fecal transplant in obese teens led to smaller waistlines and reduced body fat for at least four years.• Light-Powered AI: Researchers in Florida have built a light-based AI chip that is 100 times more energy-efficient than traditional processors by using microscopic lenses instead of just electricity.• A Biodiversity Boom: Scientists are discovering new species faster than ever before, with over 16,000 new species described every year, including hundreds of new vertebrates.• Injectable Brain Chips: MIT scientists have developed tiny electronic implants smaller than a cell that can be injected into the bloodstream to treat brain inflammation without the need for open-brain surgery.

I’m Andrew McGivern, and today we are exploring some truly mind-blowing medical and environmental breakthroughs.What if a terminal disease like ALS could be completely reversed using AI-guided "fever therapy"? That is our lead story today. Plus, we’ll look at a new toothpaste made from hair that can regrow your tooth enamel, a super-kelp that is healing our oceans while making delicious hot sauce, and a vaccine that could end deadly food allergies forever.Stay tuned for our speed round, where we’ll cover everything from self-healing bones to EV batteries that charge in just ten minutes.

Our lead story today is a medical milestone that many thought was impossible. The BTT Medical Institute has documented what they describe as the first confirmed case of a total reversal of Amyotrophic Lateral Sclerosis, or ALS.The patient, a 56-year-old woman, saw her condition progress despite standard treatments. However, after undergoing a novel, non-invasive therapy called Computerized Brain‑Guided Intelligent Thermofebrile Therapy (CBIT), she experienced a full recovery. This AI-controlled system modulates brain temperature in real time to induce a therapeutic “fever,” which triggers the body to clear away the misfolded proteins linked to the disease.Formal clinical trials are set to begin in early 2026 to see if this incredible success can be replicated for others.

Moving from the brain to the mouth—scientists at King’s College London may have found the secret to permanent, cavity-proof teeth in a very unlikely place: your hair.

In lab tests, scientists extracted keratin from wool and applied it to teeth, where it acted as a scaffold to attract calcium and phosphate ions, building a durable new shell. This biotech approach could hit the market in just two to three years, offering a sustainable, non-toxic alternative to plastic-based dental resins.Next, we head to the chilly waters of Alaska, where a "super-organism" is fighting climate change one foot at a time. Alaskan kelp can grow up to a foot in a single day, making it one of the fastest-growing organisms on Earth.A company called Barnacle Foods is turning this "bamboo of the sea" into everyday products like hot sauce and pickles. Why is this great news? Because kelp is an environmental powerhouse; it absorbs carbon dioxide from seawater, produces oxygen, and buffers ocean acidification.It’s also incredibly healthy for us, packed with natural iodine, magnesium, and omega-3s. By eating kelp-based chili crisp, you’re supporting a food system that requires zero fertilizer or freshwater and helps restore marine habitats.
