WHO chief says 'Disease X' preparation treaty in jeopardy, loss of sovereignty is ‘fake news’
The head of the World Health Organization (WHO) has said that the organization’s May deadline for getting a global pandemic treaty agreed to prepare for “Disease X” is in jeopardy and any notion that the accord would cede national sovereignty is the result of “fake news, lies, and conspiracy theories.”
WHO Director-General Tedros Ghebreyesus complained that “several outstanding issues” still needed to be resolved by governments and that time was “very short” to find consensus. World leaders and officials had previously committed to a May deadline but Tedros, who goes by his first name, said he fears that the cutoff date is at risk of not being met.
“I must say that I’m concerned that member states may not make that commitment,” Tedros said in front of the WHO’s executive board in Geneva on Monday.
“A failure to deliver the pandemic agreement and the IHR (International Health Regulations) amendments will be a missed opportunity for which future generations may not forgive us,” Tedros said.

WHO DIRECTOR CALLS FOR WORLD PANDEMIC TREATY TO PREPARE FOR DISEASE X
The IHR is a legally binding agreement that requires countries – including the U.S. – to conduct surveillance for potential international health threats of all kinds and report those to the WHO in a timely manner.
Tedros told the World Economic Forum last week that COVID-19 was the first Disease X and called on nations to sign up to the treaty so that there can be a collective response should another pandemic strike.
Disease X is a hypothetical “placeholder” virus that has not yet been formed, but scientists say it could be 20 times deadlier than COVID-19. It was added to the WHO’s short list of pathogens for research in 2017 that could cause a “serious international epidemic,” according to a 2022 WHO press release.
“Over the past two years, the intergovernmental negotiating body and the working group on amendments to the IHR, have been moving toward a common goal: to build a healthier, safer, and more equitable world,” Tedros said.
“This is our chance – maybe our only chance – to get this done, because we have the momentum.”
Tedros did not mention Disease X by name in the speech, but warned of “emerging threats” and said a treaty was urgently needed to strengthen “pandemic prevention, preparedness and response.”

Tedros argued that by putting the agreement in place, nations would have timely access to critical response products, such as diagnostics, therapeutics and vaccines.
“This is the only way we can make the world safer for our children, and our children’s children – through working together,” Tedros said. “It is difficult to overstate the importance and urgency of this work.”
Critics, including Advancing American Freedom (AAF), argue that the legally binding treaty would cede sovereignty to a global organization and that it amounts to a power grab. The AAF is a non-profit advocacy group founded by former Vice President Mike Pence.
“The [WHO] proposal to consolidate power and erode the United States of America of its sovereignty through the WHO Pandemic Preparedness Treaty is untenable and raises serious and significant questions regarding America’s independence of action and ability to respond to global pandemics,” a letter published by the AAF on Tuesday reads.
Furthermore, the AAF points out that the treaty — ostensibly intended to save lives through international prioritization of the best medical practices — emphasizes race and “equity” before almost every other value in its “general principles and approaches.”

“It presents ‘equity’ as its third general principle, ahead of responsibility, transparency, accountability, and science and evidence – principles that are magnitudes more important than ‘equity’ during a global pandemic,” the letter reads.
Tedros, in his Monday speech, dismissed suggestions the pact would result in countries losing sovereignty.
“There are those who claim that the pandemic agreement and IHR will cede sovereignty to WHO and give the WHO Secretariat the power to impose lockdowns or vaccine mandates on countries. You know this is fake news, lies, and conspiracy theories,” Tedros said.
“These claims are completely false. You know that the agreement will give WHO no such powers, because you are writing it.”

Key fitness measure is strong predictor of longevity after certain age, study finds
NEWYou can now listen to Fox News articles!
For women over 60, muscle strength plays a critical role in longevity, a new study confirms.
Researchers at the University at Buffalo, New York, followed more than 5,000 women between the ages of 63 and 99, finding that those with greater muscle strength had a significantly lower risk of death over an eight-year period.
The findings were published in JAMA Network Open.

Muscle function was measured using grip strength and how quickly participants could complete five unassisted sit-to-stand chair raises.
These are two tests commonly used in clinical settings to evaluate muscle function in older adults, the researchers noted.

“In a community cohort of ambulatory older women, muscular strength was associated with significantly lower mortality rates, even when we accounted for usual physical activity and sedentary time measured using a wearable monitor, gait speed and blood C-reactive protein levels,” study lead author Michael LaMonte, research professor of epidemiology and environmental health at the University at Buffalo, told Fox News Digital.
“Movement is the key — just move more and sit less.”
Many earlier studies did not include those objective measurements, making it difficult to determine whether muscle strength itself was linked to longevity, according to LaMonte. “Our study was able to better isolate the association between strength and death in later life,” he added.
Even for women who don’t get the recommended amount of aerobic physical activity, which is at least 150 minutes per week, muscle strength remained important for longevity, the researchers found.

“The findings of lower mortality in those who had higher strength but were not meeting current national guidelines on aerobic activity were somewhat intriguing,” LaMonte said.

Federal guidelines recommend strengthening activities one to two days per week, targeting major muscle groups.
Resistance training does not have to require a gym membership, LaMonte noted. These exercises can be performed using free weights, resistance bands, bodyweight movements or even household items, such as soup cans.

“Movement is the key — just move more and sit less,” he said. “When we can no longer get out of the chair and move around, we are in trouble.”

LaMonte acknowledged several limitations of the study. The researchers assessed muscle strength in older age but did not explore how earlier levels in adulthood might influence long-term health outcomes.

“We were not able to understand how strength and mortality relate in younger ages,” he said, noting that future research should explore whether building strength earlier could have an even greater impact on longevity.

Cannabis compounds could reverse disease affecting one-third of adults
NEWYou can now listen to Fox News articles!
Compounds found in cannabis could provide a new roadmap for treating the world’s most common chronic liver disorder, according to a study released by the Hebrew University of Jerusalem.
The research, published in the British Journal of Pharmacology, found that cannabidiol (CBD) and cannabigerol (CBG) significantly reduced liver fat and improved metabolic health in experimental models.
CBD is the more widely studied non-intoxicating cannabinoid, while CBG is a less common “precursor” cannabinoid from which CBD is formed.

Unlike THC, the primary psychoactive component in cannabis, these compounds do not produce a “high,” making them viable candidates for long-term medical treatment, the study suggests.
Metabolic dysfunction-associated steatotic liver disease (MASLD) currently affects approximately one-third of the global adult population, according to health data.

The condition, which is closely linked to obesity and insulin resistance, has few approved pharmaceutical treatments, the researchers said, leaving patients to rely largely on lifestyle changes that can be difficult to maintain.
“Our findings identify a new mechanism by which CBD and CBG enhance hepatic energy and lysosomal function,” said lead study author Joseph Tam, director of the Multidisciplinary Center for Cannabinoid Research at Hebrew University, in a press release.
MARIJUANA COMPOUND MAY HELP PREVENT DEMENTIA WHEN PAIRED WITH COMMON DRUG
The study highlights a process called “metabolic remodeling,” in which the cannabis compounds created a “backup battery” for the liver by increasing levels of phosphocreatine, a high-energy molecule stored in muscle cells.
This energy reserve helps the organ function under the stress of a high-fat diet, which was an unexpected discovery, the team noted.
Researchers focused on CBD and CBG, two non-psychoactive compounds that offer therapeutic benefits without the “high” associated with THC. (iStock)
The researchers also found that CBD and CBG restored the activity of “cellular cleaning crews” known as cathepsins, enzymes that work within the cell’s recycling centers to break down harmful fats and waste.
With this process, the liver was better able to clear out dangerous lipids, including triglycerides and ceramides, which are known to trigger inflammation, the study showed.

While both compounds were effective, CBG showed more robust results in certain areas, such as reducing total body fat mass, lowering “bad” LDL cholesterol and improving insulin sensitivity.
Researchers say this study opens a new path for using plant-based compounds to treat metabolic diseases by focusing on how cells manage energy and waste.

Limitations and caveats
Despite the promising results, the research team cautioned that the study was conducted in a controlled experimental environment. Further clinical trials are necessary to determine the proper application for human patients.

A major analysis published in JAMA examined more than 2,500 scientific papers from the last 15 years, including other reviews, clinical trials and guidelines focused on medical marijuana.
The 2025 review highlighted significant gaps between public perception and scientific evidence regarding cannabis’ effectiveness for most medical conditions.

The researchers concluded that there are very few conditions for which cannabinoid therapies have clear, well-established benefits backed by high-quality clinical data.
“Whenever a substance is widely used, there is likely to be a very wide set of outcomes,” Alex Dimitriu, MD, who is double board-certified in psychiatry and sleep medicine and founder of Menlo Park Psychiatry & Sleep Medicine, previously told Fox News Digital. “This study points to the reality that this widely used substance is not a panacea.”

Study challenges negative cannabis stereotypes, claiming link to brain benefits
NEWYou can now listen to Fox News articles!
While cannabis has recently come under fire for potential negative health risks, a recent study suggests that its use could increase brain volume and cognitive fitness.
Researchers at the University of Colorado Anschutz Medical Campus analyzed cannabis usage, brain scans and cognitive test results for more than 26,000 adults between the ages of 40 and 77, using data from the UK biobank.
The study found that cannabis users — particularly those who reported moderate lifetime usage — showed larger volumes in several brain regions.

“Compared to individuals with no history of cannabis use, those who reported using cannabis showed larger volumes in several brain regions characterized by a high density of cannabinoid (CB1) receptors — regions involved in processes such as memory, information processing and emotion regulation,” lead study author Anika Guha, Ph.D., a researcher at the University of Colorado Anschutz Medical Campus, told Fox News Digital.

The cannabis users also scored better on cognitive tests that measured learning, processing speed and executive function.
This outcome differs from many previous studies, which have focused on short-term cognitive impairment during or shortly after cannabis use, the researcher pointed out.

“These findings suggest that the relationship between cannabis and the brain may differ across the lifespan, and that moderate use in mid-to-later adulthood may be associated with positive brain health outcomes,” Guha said.
Not all areas of the brain showed positive effects among cannabis users. The posterior cingulate, which is involved in self-reflection and memory, had lower volume with higher marijuana use.
“The takeaway is not that people should start using more cannabis based on these findings alone.”
As cannabis has been rising in popularity among all ages, this type of study is important for understanding its long-term effects and the pros and cons of use, according to Matt Glowiak, Ph.D., chief addiction specialist with Recovered, an organization that provides information and resources for mental health and addiction treatment.

“Given the connection between cannabis use and larger brain volume, it is believed that it may help [older] individuals retain cognitive function that might otherwise naturally decline,” Chicago-based Glowiak, who was not involved in the study, told Fox News Digital.
“This is a huge benefit, but one we need to explore a bit further, ahead of encouraging those who would otherwise not consider integrating cannabis into their healthcare regimen.”
Limitations and caveats
As the study was observational in nature, it could not prove that cannabis use improves brain health — instead, it only showed an association, according to Dr. Marc Siegel, Fox News senior medical analyst, who was not involved in the study.
“The preponderance of previous evidence does not line up with improved cognitive function from chronic cannabis use,” Siegel told Fox News Digital. “This study is an outlier, and though it cannot be ignored, it is not justification for use.”

The study also relied on the UK Biobank, which offers a “large and rich dataset,” Guha said — but it is limited to the questions that were originally posed to the participants.
“In particular, we have only a broad measure of how many times someone has used cannabis over their lifetime,” she said. “We do not have access to details about how they used cannabis, such as whether they smoked or used edibles, the type or potency of cannabis, or when in their life they used most heavily.”

“Those details likely matter a great deal for understanding how cannabis affects the aging brain.”
Given these limitations, Guha suggests that the findings should be seen as an early indicator that cannabis use may be related to brain aging, “and as a starting point for more targeted research that can tease apart these relationships.”

“The takeaway is not that people should start using more cannabis based on these findings alone,” she emphasized. “While cannabis may have potential benefits in some contexts, a substantial body of research also documents important risks, underscoring that cannabis is neither completely beneficial nor completely harmful.”
The drug’s effects likely depend on factors such as age, dose, frequency, product composition and individual vulnerability, according to Guha.
“Given the widespread use and legalization of cannabis, it would be great to know that it is net-positive for brain health — however, this feels too good to be true, and too early to claim,” one expert said. (AP)
“As with any substance, individuals should consult with a healthcare provider before initiating use, particularly if they have a history of mental health concerns, as THC (the primary psychoactive component of cannabis) can exacerbate symptoms such as psychosis in vulnerable individuals,” she added.
Dr. Alex Dimitriu, who is double board-certified in psychiatry and sleep medicine and the founder of Menlo Park Psychiatry & Sleep Medicine, reiterated that this study is an “outlier,” as most previous research has shown “detrimental effects” from cannabis use.

Dimitriu agreed that more large-scale studies and review papers are needed to get a “clearer picture.”
“What this cannabis study shows is that there may be conflicting information, which warrants more investigation.”
