(Press-News.org) Researchers have discovered that non-psychoactive cannabis compounds, CBD and CBG, can significantly reduce liver fat and improve metabolic health. The study reveals that these compounds work by creating a backup energy reserve in the liver and restoring the activity of cellular "cleaning crews" to break down harmful waste. These findings highlight a new, plant-based path for treating the world’s most common chronic liver disorder.
A study led by Prof. Joseph (Yossi) Tam, Dr. Liad Hinden, the PhD student Radka Kočvarová, and the Tam’s team at the School of Pharmacy at the Faculty of Medicine of the Hebrew University of Jerusalem has found that two compounds from the cannabis plant could help treat fatty liver disease. The research suggests that Cannabidiol (CBD) and Cannabigerol (CBG), which are non-psychoactive and do not cause a high, can improve liver health by changing how the organ manages energy and cleans itself.
Metabolic dysfunction-associated steatotic liver disease (MASLD) is currently the most common chronic liver disorder in the world. It affects approximately one-third of the adult population and is closely linked to obesity, high blood pressure, and insulin resistance. While lifestyle changes like diet and exercise are important, they can be hard to maintain, and there are very few approved medicines available for this condition. This makes the search for new treatments a high priority for scientists.
The researchers used advanced tools to show that CBD and CBG do more than just reduce fat. They actually help the liver function better internally through a unique process of "metabolic remodeling". One of the most important findings was the impact on the liver's energy reserves. These compounds increase levels of phosphocreatine, which acts like a backup battery to help the liver stay healthy under the stress caused by a high-fat diet. This is a new discovery, as the liver does not usually rely heavily on this specific energy system.
Additionally, the study showed that CBD and CBG restore the activity of cathepsins. These are enzymes that act like a cleaning crew within the cell's recycling centers, known as lysosomes. By getting this cleaning crew back to work, the liver is better able to break down and clear out harmful fats and waste. The researchers also found that both treatments significantly reduced harmful lipids, such as triglycerides and ceramides. Ceramides are particularly dangerous because they are known to contribute to insulin resistance and liver inflammation.
The study observed that while both compounds were effective, they each provided slightly different benefits for metabolic health. Both CBD and CBG were able to normalize blood sugar levels and improve how the body clears glucose. However, CBG appeared to have a more pronounced effect on certain metrics. It significantly reduced body fat mass and improved insulin sensitivity more robustly than CBD. CBG was also particularly effective at lowering total cholesterol and "bad" LDL cholesterol levels.
"Our findings identify a new mechanism by which CBD and CBG enhance hepatic energy and lysosomal function," says Prof. Joseph Tam. "This dual metabolic remodeling contributes to improved liver lipid handling and highlights these compounds as promising therapeutic agents for MASLD".
While these results are very encouraging, the team notes that more research is needed to understand how these findings can best be applied to human patients. This study opens a new path for using plant-based compounds to treat metabolic diseases by focusing on how cells manage energy and waste.

Study in mice reveals the brain circuits behind why we help others
2026-03-05
Humans and animals share a remarkable capacity to sense when others are in distress and respond with comforting behavior. But the motivation for doing so, and why it sometimes breaks down, has been poorly understood. UCLA Health researchers sought to better understand this in a new study published in Nature that uncovered the brain circuitry in mice linking two seemingly distinct social behaviors: caring for vulnerable offspring and comforting distressed peers. The findings provide the first direct neural evidence for a long-standing evolutionary ...

Turning agricultural plastic waste into valuable chemicals with biochar catalysts
2026-03-05
Agricultural plastic mulch films are widely used around the world to increase crop yields, conserve soil moisture, and suppress weeds. However, once these films are discarded, they can persist in the environment for decades, contributing to soil contamination and plastic pollution. A new study shows that these difficult to recycle plastics could instead be transformed into valuable chemical products using a biochar based catalytic process.
Researchers investigated a method for converting waste plastic mulch film into useful chemicals through catalytic pyrolysis. In this process, plastic is heated in the absence of oxygen, causing the long polymer ...
Hidden viral networks in soil microplastics may shape the future of sustainable agriculture
2026-03-05
Microplastics are widely recognized as pollutants in oceans and waterways, but scientists are increasingly discovering that they are also accumulating in agricultural soils. A new scientific review highlights a largely overlooked dimension of this problem: the complex interactions between soil microbes and viruses that occur on the surface of microplastic particles. The study reveals that these microscopic relationships may influence soil health, ecosystem recovery, and the long term sustainability of agriculture.
Microplastics are tiny plastic fragments smaller than five millimeters that enter farmland ...
Americans don’t just fear driverless cars will crash — they fear mass job losses
2026-03-05
Key Takeaways
More than 60% of Americans said they would probably or definitely avoid riding in a driverless car.
About 85% said widespread AVs would cause job losses in ride-hailing, ridesharing and delivery work.
More than 46% said AVs would widen the income gap (vs about 6% who said it would narrow).
The survey found a social and geographic divide: tech-aware, educated groups show strong adoption interest but economic concern, while lower-income and non-metro respondents remain unwilling and skeptical.
While much of the public debate about self-driving cars focuses on safety, a new national study from the University of California San Diego ...

Carbon nanotube fiber ‘textile’ heaters could help industry electrify high-temperature gas heating
2026-03-05
A cross-disciplinary team at Rice University has developed a new type of electric heating element — one that looks less like a traditional metal coil and more like a high-performance thread.
In a study published in Small, the researchers demonstrated that wires and fabrics made from carbon nanotube fibers (CNTFs) can deliver substantially more heating power per unit mass than conventional metal-alloy heaters when placed directly in flowing gases. The findings point to a potential new pathway for electrifying industrial heating, a critical but technically challenging step toward reducing carbon emissions.
“Electrifying industrial heat is one of the most important, and most difficult, ...
Improving your biological age gap is associated with better brain health
2026-03-05
Highlights:
Improving the gap between your biological age and your actual age is associated with a lower risk of stroke and better brain health.
The study involved 250,000 people. Researchers measured 18 biomarkers in their blood to determine their biological age. A subset of people also had brain scans.
People who improved the gap between their biological and chronological ages during the study were 23% less likely to have a stroke afterward than those who did not.
The study does not prove that improving the age gap is the cause of the lower risk of stroke and brain health improvements. It only shows an association.
Researchers say eating a healthy diet, ...
Learning makes brain cells work together, not apart
2026-03-05
When you get better at a skill—recognizing a familiar face in a crowd, spotting a typo at a glance, or anticipating the next move in a game—sensory neurons in your brain become more coordinated, sharing information rather than acting more independently. That’s the conclusion of a new study by researchers at the University of Rochester and its Del Monte Institute for Neuroscience, published in Science, which challenges a long-held assumption in neuroscience that learning improves efficiency ...
