The Brain Feed

Neuroscience research is advancing new ways to support spinal cord repair using injectable biomaterials combined with regenerative cells. These materials are designed to create a supportive environment that helps nerve fibers regrow across injured areas.

In laboratory and animal studies, biocompatible gels containing stem cells and growth-supporting signals improved nerve signaling and motor recovery. The material gradually dissolves as new tissue forms, allowing natural repair processes to continue.

While early results are promising, this research is still under controlled clinical investigation. Scientists emphasize that further trials are required to confirm safety, effectiveness, and long-term outcomes before widespread human use.

Breastfeeding during an infant’s first year provides powerful health benefits. Exclusive breastfeeding for the first six months, and continued breastfeeding up to about twelve months, supports immune function, brain development, craniofacial growth, and overall wellness. Research consistently shows benefits for both systemic and oral health in early infancy.

After twelve months, however, frequent breastfeeding combined with solid foods especially during nighttime may increase the risk of early childhood caries. This happens due to prolonged exposure to natural sugars and reduced saliva flow during sleep.

These findings do not reduce breastfeeding’s importance. With gentle brushing once teeth erupt and thoughtful management of nighttime feeds, caregivers can support healthy teeth while preserving breastfeeding’s well-documented benefits.

Epigenetic research is changing how scientists understand inheritance. S***m is not just a carrier of DNA; it also contains epigenetic markers chemical signals influenced by a man’s environment and habits in the months before conception. Diet, stress, sleep, alcohol use, smoking, and overall health can affect how these markers regulate gene activity during early development.

While the DNA sequence itself does not change, the way genes are switched on or off can. Studies have linked paternal epigenetic signals to outcomes involving metabolism, immune function, stress response, and aspects of brain development.

These findings highlight that preconception health is not one-sided. Alongside maternal health, paternal biology also contributes meaningful biological context to the next generation suggesting fatherhood begins earlier than most people realize.

After braces are removed, teeth naturally tend to move toward their original positions, a process known as orthodontic relapse. This happens because the surrounding bone and periodontal ligaments need time to remodel and stabilize after treatment.

Retainers are essential for holding teeth in their new alignment while these supporting structures adapt. Without consistent retainer wear, unwanted tooth movement can compromise the results of orthodontic treatment.

The American Association of Orthodontists stresses that wearing retainers exactly as prescribed is key to long-term success. Consistent use helps keep your smile aligned and protects the time and investment you made in your braces.

A new lab study reveals that stevia, when fermented with the bacterial strain Lactobacillus plantarum SN13T, becomes much more potent against pancreatic cancer cells. Researchers created a fermented stevia extract and tested it on cancerous pancreatic cells as well as healthy kidney cells. The result: the fermented extract triggered cancer cell death, prevented their growth, and blocked their spread, while leaving healthy cells largely unaffected.

The key lies in a compound called chlorogenic acid methyl ester (CAME), produced during fermentation. CAME appears to powerfully induce apoptosis, or programmed cell death, in cancer cells, and also hinders their ability to form new colonies. These lab findings suggest a promising natural approach to targeting one of the most aggressive forms of cancer.

It’s important to note that this research is still in early stages. Tests were performed in lab dishes, and more studies in animals are needed to assess safety, dosage, and effectiveness before considering human applications. While exciting, consuming stevia or supplements is not yet proven to treat pancreatic cancer.

At just 17, Joe Landolina turned a high school experiment in his grandfather’s winery lab into a medical breakthrough. By experimenting with polymers extracted from algae, he discovered a gel that can instantly stop bleeding and start the healing process. This innovation addresses one of the leading causes of prehospital deaths, where severe injuries can claim lives in minutes.

Landolina’s gel, TRAUMAGEL, comes in a syringe and is applied directly to wounds. Unlike traditional methods like pressure or packing, it halts bleeding immediately, giving medics and patients critical extra time to reach advanced care. Its rapid effectiveness has made it an invaluable tool for firefighters, first responders, and the military.

After showcasing his work at New York University’s business plan competition, Landolina founded Cresilon, the biotech company behind TRAUMAGEL. The invention has since earned recognition worldwide, transforming emergency trauma care and earning a nomination for Best Medical Technology at the Prix Galien USA 2025.

A new study highlights a troubling link between fine particulate air pollution (PM2.5) and Lewy body dementia, a major cause of neurodegenerative disorders. Researchers found that exposure to these tiny airborne particles can trigger harmful clumps of the protein alpha-synuclein, which are central to Parkinson’s disease dementia and dementia with Lewy bodies.

Laboratory studies in mice showed that PM2.5 exposure caused brain shrinkage, cognitive decline, and widespread protein deposits. Mice lacking alpha-synuclein did not develop these symptoms, underscoring the protein’s key role. Additionally, analysis of over 56 million U.S. Medicare records revealed that people in areas with higher PM2.5 levels had a significantly increased risk of hospitalization for Lewy body dementia. For every 4.14 µg/m³ rise in PM2.5, hospitalization risk rose 17% for Parkinson’s disease dementia and 12% for dementia with Lewy bodies.

These findings suggest that air pollution is a potentially modifiable risk factor. Reducing exposure to fine particulate matter could help protect brain health and lower the likelihood of developing these debilitating conditions.

Egg freezing is becoming increasingly popular as people delay parenthood, offering a way to “pause” fertility for future use. The process involves hormone injections to stimulate the ovaries, retrieval of multiple eggs, and storage in liquid nitrogen until a woman is ready to try for pregnancy. Later, the eggs are thawed, fertilized, and implanted, similar to in vitro fertilization (IVF).

However, success is not guaranteed. Age plays a major role freezing eggs in your 20s or early 30s generally provides higher quality and quantity. Even then, not every egg survives thawing, fertilizes successfully, or leads to a pregnancy. Multiple cycles may be required, adding cost, stress, and uncertainty.

Experts caution that while egg freezing offers reassurance, it is not a replacement for supportive family policies. Better parental leave, flexible work arrangements, and childcare options may reduce the pressure to rely solely on fertility technologies, making family planning more realistic and less stressful.

Researchers have discovered a hidden protein called CD36 that could revolutionize how cancer medicines work. CD36 acts as a gateway, allowing large, complex drugs like PROTACs, which normally struggle to enter cells to pass through via endocytosis, a natural cellular intake process. By targeting CD36, scientists boosted drug entry over twentyfold, dramatically increasing their effectiveness at destroying cancer-causing proteins.

PROTACs differ from traditional cancer drugs because they don’t just block harmful proteins they mark them for complete destruction. This reduces drug resistance and opens possibilities for treating cancers and other diseases previously considered untreatable. Laboratory and animal studies show that CD36-targeted PROTACs suppress tumors much more effectively without losing stability.

This strategy, called chemical endocytic medicinal chemistry (CEMC), could rescue many large drugs that were once abandoned and may also benefit therapies for Alzheimer’s, autoimmune disorders, and infections. The next step is human clinical trials to confirm safety and effectiveness, potentially marking a major shift in life-saving drug delivery.

Diffuse intrinsic pontine glioma (DIPG) is a devastating childhood brainstem cancer with historically grim outcomes. Most children survive less than two years after diagnosis, and until recently, there had been no effective treatments. That changed when six-year-old Lucas joined a clinical trial in France testing the drug everolimus.

Everolimus works by blocking mTOR, a protein tumors use to grow and develop blood supply. Administered daily, the drug gradually shrank Lucas’ tumor until it completely disappeared. Now thirteen, he is the first person officially cured of DIPG. Doctors believe a rare genetic mutation in his tumor made it unusually sensitive to the treatment, while other trial participants have also experienced longer survival than expected.

Researchers hope to study Lucas’ response in lab-grown tumor models to identify why the drug was so effective, aiming to replicate the result in more patients. Early immunotherapy studies also show promise. While DIPG remains a challenging cancer, Lucas’ story offers a newfound spark of hope for families facing this diagnosis.

Researchers have identified a new strategy to limit the spread of glioblastoma by changing the environment around the tumor rather than targeting the tumor cells directly. Their work focuses on hyaluronic acid (HA), a natural structural molecule in the brain that helps cells move and communicate.

In its flexible form, HA allows tumor cells to attach to surface receptors and activate signals that encourage movement into nearby healthy tissue. By chemically cross-linking HA and making it more rigid, scientists blocked this interaction. As a result, tumor cells lost their ability to migrate, even though they remained alive.

This approach suggests that reshaping the tumor’s microenvironment could slow disease progression without relying on harsh treatments. The findings open the door to new therapies that focus on controlling spread rather than destroying cells, which may reduce side effects and improve long-term outcomes.

A newly approved prescription eye drop called VIZZ is offering a new option for people with presbyopia, the common age-related loss of near focus that usually begins after 45. The drop uses aceclidine to gently reduce pupil size, creating a pinhole effect that improves near vision for up to ten hours with a single daily dose.

Unlike earlier treatments, VIZZ works only on the pupil and does not affect the muscle that controls lens shape. This helps preserve clear distance vision while enhancing the ability to read phones, menus, and books. In large clinical trials spanning tens of thousands of treatment days, users reported improved near clarity with mostly mild and temporary side effects.

Researchers say this targeted approach avoids many drawbacks seen with older drops. VIZZ is expected to become available by prescription in late 2025, potentially reducing dependence on reading glasses for millions of adults.
