One Injection. Permanent GLP-1? The Future of Weight Loss & Metabolic Therapy

A company called Fractal Health is developing a one-time GLP-1 gene therapy and the first humans are being dosed this year.

Instead of weekly injections like semaglutide or tirzepatide, this approach delivers genes directly into pancreatic beta cells. The therapy is controlled by the insulin promoter, meaning GLP-1 is only released when you eat — not continuously.

That could mean fewer systemic side effects and a more physiologic response.

They’re developing two versions:
• GLP-1 alone.
• GLP-1 + GIP (similar to tirzepatide)

One injection. Potentially permanent metabolic support.

If this works, it could redefine obesity and diabetes treatment.

Standard mental health tests may be inaccurate for highly intelligent people

The researchers found that as intelligence scores rise, the questions on common mental health surveys lose their ability to consistently measure the underlying psychological condition. These results were published in the journal Intelligence.

The concept of the “tortured genius” is a cultural staple. It suggests that high intelligence is accompanied by social isolation, existential anxiety, or other psychological difficulties. Previous research on this topic has produced conflicting results. Many large-scale studies indicate that intelligence generally correlates with better health and happiness.

However, other researchers argue that this relationship might not be a simple straight line. They propose a “nonlinear” relationship. This means intelligence could be protective up to a certain point, but extremely high levels might eventually lead to negative outcomes. This phenomenon is sometimes called the “too-much-of-a-good-thing” effect.

The Deflationary Singularity: Why Everything is Going to ZERO w/ Salim Ismail

The rapid advancement of technologies, particularly AI, is driving the world towards an economic singularity where the marginal cost of essentials approaches zero, leading to a deflationary future and a potential transformation of traditional systems and societies ##

## Questions to inspire discussion.

Education Transformation.

🎓 Q: How will AI reduce education time while improving effectiveness?

A: AI will customize education to each child’s learning style, reducing daily learning time to 1 hour per day while delivering 5 times more effective learning compared to traditional methods, with costs falling to zero within 3–5 years and breaking the university industry that currently creates massive student debt.

Healthcare Revolution.

Peripheral Neural Plasticity in Cochlear Implant Users Across the Lifespan

Model-based analysis of ECAPs in CochlearImplant users showed stronger auditory nerve responses and plasticity in younger recipients, highlighting the value of early implantation.

Question Can neural responses measured in cochlear implant users be standardized to monitor auditory nerve health and plasticity over time?

Findings In this cohort study analyzing more than 169 000 recordings from more than 10 000 cochlear implants in 7,416 patients, auditory nerve activity varied by cochlear location and age at implantation. Children implanted at younger ages showed stronger responses and clear evidence of plasticity, particularly in the first 5 years after activation; these changes were not observed in older users.

Meaning Model-based analysis of neural recordings provide a scalable method for tracking auditory nerve health across the lifespan and highlight the importance of early implantation for long-term outcomes.

Studies show 11 genetic variants affect gut microbiome

In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do there. Only two genetic regions were previously known. Some of the new genetic variants can be linked to an increased risk of gluten intolerance, hemorrhoids and cardiovascular diseases.

The studies are published in the journal Nature Genetics.

The community of bacteria living in our gut, or gut microbiome, has become a hot research area in recent years because of its great significance for health and disease. However, the extent to which our genes determine which bacteria are present in the intestines has been unclear. Until now, it has only been possible to link a few genetic variants to the composition of the gut microbiome with certainty.

Early signs of Parkinson’s can be identified in the blood

A team led by researchers at Chalmers University of Technology, Sweden, has succeeded in identifying biomarkers for Parkinson’s disease in its earliest stages, before extensive brain damage has occurred. The biological processes leave measurable traces in the blood, but only for a limited period.

The discovery thus reveals a window of opportunity that could be crucial for future treatment, but also for early diagnosis via blood tests, which could begin to be tested in health care within five years.

Parkinson’s is an endemic disease with over 10 million people affected globally. As the world’s population grows older, this number is expected to more than double by 2050. At present, there is neither an effective cure nor an established screening method for detecting this chronic neurological disorder at an early stage before it has caused significant damage to the brain.

New clue to treating hypertension: Blocking a brain receptor may calm blood pressure signals

The human body is often described in parts—different limbs, systems, and organs—rather than something fully interconnected and whole. Yet many bodily processes interact in ways we may not always recognize. For example, researchers at the University of Missouri School of Medicine may have found a link between high blood pressure and an overactive nervous system.

The paper is published in the journal Cardiovascular Research.

High blood pressure, also called hypertension, is a common cardiovascular condition and a risk factor for multiple diseases and sudden health concerns like stroke or heart attack.

Study of 65,000 college students links 16 hours a week on social media to higher loneliness

More than half of college students are lonely—and those who use social media the most are particularly likely to feel isolated, a study of tens of thousands of 18 to 24-year-olds in the US shows. Just 16 hours a week—two or so hours a day—on social media was linked with higher odds of loneliness, reports a paper in the Journal of American College Health.

The study’s authors said that academic institutions should educate students on the effects of social media use and encourage them to set time limits.

Researcher Dr. Madelyn Hill, now an assistant professor at Ohio University, who led the study while completing her doctoral work in University of Cincinnati’s School of Human Services in spring 2025, explains, We know that people who are lonely are more likely to become depressed. We also know that those who are lonely are more likely to die early.

New sound-based 3D-printing method enables finer, faster microdevices

Concordia researchers have developed a new 3D-printing technique that uses sound waves to directly print tiny structures onto soft polymers like silicone with far greater precision than before. The approach, called proximal sound printing, opens new possibilities for manufacturing microscale devices used in health care, environmental monitoring and advanced sensors. It is described in the journal Microsystems & Nanoengineering.

The technique relies on focused ultrasound to trigger chemical reactions that solidify liquid polymers exactly where printing is needed. Unlike conventional methods that rely on heat or light, sound-based 3D-printing works with key materials used in microfluidic devices, lab-on-a-chip systems and soft electronics that are hard to print at small scales.

This work builds on the research team’s earlier breakthrough in direct sound printing, which first showed that ultrasound could be used to cure polymers on demand. While that earlier method demonstrated the concept, it struggled with limited resolution and consistency. The new proximal approach places the sound source much closer to the printing surface, allowing far tighter control.
