An experimental treatment happens to be the solution to delay Alzheimer's symptoms in some people. These people are the ones who are genetically destined to get the disease in their 40s or 50s. These new findings form ongoing research has now been caught up in Trump administration funding delas. The early results of the study has been published on Wednesday and the participants too are worried that politics could cut their access to a possible lifeline.

One of the participants had said, "It is still a study but it has given me an extension to my life that I never banked on having." The participant is named Jake Henrichs, form New York City, who is 50 years old. He is one of them to be treated in that study for more than a decade now and has remained symptom-free despite inheriting an Alzheimer's-causing gene that had killed his father and brother around the same age.

Slowing Down The Symptoms

Two drugs which can modestly slow down early-stage Alzheimer's are sold in the United States. These drugs clear the brain of one of its hallmarks, a sticky gunk-like part called the amyloid. However, there have not been any hints that removing amyloid far earlier, way many years before the first symptoms appear, may postpone the disease.

How Was The Research Conducted?

The research is led by Washington University in St Louis, which involved families that passed down rare gene mutation as participants. This meant it was almost guaranteed that they will develop symptoms at the same age their affected relatives did.

The new findings is based on a subset of 22 participants who received amyloid-removing drugs the longest, on average eight years. Long-term amyloid removal cut in half their risk of symptom onset. The study is published in the journal Lancet Neurology.

Washington University's Dr Randall Bateman, who directs the Dominantly Inherited Alzheimer's Network of studies involving families with these rare genes says, "What we want to determine over the next five years is how strong is the protection. Will they ever get the symptoms of Alzheimer’s disease if we keep treating them?”

The researchers before though did not know what exactly caused Alzheimer's which affects nearly 7 million Americans, most of them in their later life. However, it is clear that these silent changes occur in the brain at least two decades before the first symptom shows up. The big contributor. At some point amyloid buildup can trigger a protein named tau that then starts to kill neurons, which can lead to cognitive decline.

Researchers are now thus studying the Tau-fighting drugs and are looking into other factors, like inflammation, brain's immune cells and certain virus.

The National Institute of Health (NIH) has expanded its focus as researchers have found more reasons for Alzheimer's. In 2013, the NIH's National Institute on Aging funded 14 trials of possible Alzheimer's drugs over a third targeting amyloid. By last fall, there were 68 drugs and 18% of them target amyloid. However, there are scientists too who think that amyloid is not everything and their is way more in the brain tissue, immune cells, and more which can be studied.

A new study has identified 485 chemicals used in pesticide products in the US that are linked to breast cancer, raising new concerns about how these chemicals are assessed for safety against serious diseases.

The peer-reviewed research, published in Environmental Health Perspectives, dug beyond the active ingredients in pesticides and examined the inactive ingredients that are often not subjected to the same level of safety scrutiny.

The study identifies chemicals associated with breast cancer risk. It does not establish that exposure to these pesticides causes breast cancer in people.

What Did The Researchers Find?

Of the 485 chemicals identified in pesticide formulations, only 145 were registered with the US Environmental Protection Agency (EPA) as active ingredients. The remaining chemicals were classified as inactive or 'inert' ingredients. These ingredients can serve different purposes, like helping pesticide ingredients spread, penetrate surfaces or become more absorbed.

The researchers argue that focusing primarily on active ingredients may overlook risks from the complete pesticide formulation.

“Our findings highlight a regulatory blind spot around so-called inert ingredients,” lead author Dr Jennifer Kay of the Silent Spring Institute said in a research release.

What Does “Inert” Mean?

An inert ingredient is generally considered 'inactive' as it does not target the pest the product is designed to kill. It does not mean that it has no biological effect on humans. According to the study's researchers, people are exposed to the entire pesticide formulation, not just the active ingredient in the pesticide.

The researchers identified around 4,000 inert ingredients approved for use by the EPA, including some PFAS, commonly known as 'forever chemicals.'

Pesticide Exposure

Pesticide exposure is not limited to agricultural workers or people living near farms. The chemicals identified in the study can also occur in products used around homes, including lawn treatments, flea and tick products and lice treatments. Pesticides can also enter the environment through food and drinking water.

The researchers found that 84 of the identified chemicals were detectable in the general US population based on data from the National Health and Nutrition Examination Survey, although they said this likely underestimates exposure because many of the compounds are not routinely tracked.

Pesticides & Breast Cancer Link

The researchers classified chemicals based on existing evidence linking them to breast cancer. That is different from demonstrating that pesticide exposure directly causes breast cancer in humans.

Breast cancer is a complex disease that involves multiple genetic, hormonal, environmental and lifestyle factors.

The study does, however, raise a question about whether the combined exposure to multiple chemicals is adequately considered during pesticide safety assessments.

The researchers noted that the EPA generally evaluates individual pesticide ingredients rather than the entire formulation or people's exposure to multiple pesticides.

The research comes as breast cancer rates, including among younger women, continue to rise in the US. According to the American Cancer Society data cited by The Guardian, breast cancer incidence has been increasing by about 1% a year, with a slightly faster increase among women under 50.

reaImagine developing a strange medical condition in which an injury or even a minor fall may trigger a process that may gradually turn muscles, tendons and ligaments into bone.

This is what fibrodysplasia ossificans progressiva (FOP), one of the world’s rarest genetic disorders, looks like.

The US Food and Drug Administration recently approved a new treatment option for FOP called Atebrioz (zilurgisertib), a once-daily pill developed by Mirum Pharmaceuticals.

Adults and children aged 12 years and above with FOP are eligible for this treatment. It is designed to reduce the formation of new bone outside the skeleton.

What Is Fibrodysplasia Ossificans Progressiva?

FOP is a rare genetic disease in which connective tissues like muscles, tendons and ligaments gradually turn into bone. The abnormal bone formation is known as heterotopic ossification, meaning bone starts to develop in places where it should not.

Over time, this can pose restriction in movement, cause deformities and lead to severe disability. The condition could affect quality of life significantly as well as shorten life expectancy.

FOP is usually diagnosed in childhood. According to Mirum, around 300 people in the US and about 900 worldwide are known to have the condition.

Why Does The Body Starts Making Bone In The Wrong Places?

FOP is caused by mutations in a gene involved in bone growth, especially the ACVR1 gene, which produces a protein called activin A receptor type-1, or ALK2. In people with FOP, this pathway becomes abnormally active. As a result, the body can start producing bone within soft tissues.

This process can occur in episodes called flare-ups. Trauma, surgery or other triggers can sometimes provoke inflammation and subsequent abnormal bone formation. The problem is that once mature bone has formed in these tissues, it can permanently restrict movement.

More About The New Drug

Atebrioz contains zilurgisertib, an oral drug that blocks ALK2, the protein that is abnormally active in most people with FOP and triggers bone formation outside the skeleton.

The aim is not to remove bone that has already formed. Instead, the treatment is designed to reduce the formation of new abnormal bone.

FDA’s approval was based on a randomised, placebo-controlled trial involving 63 people with FOP. Participants received either zilurgisertib or placebo for 24 weeks, followed by an extension period.

At week 24, patients receiving Atebrioz had an average 3.2 cm³ decrease in the volume of newly formed abnormal bone, compared to a 24.6 cm³ increase in the placebo group. The FDA said the difference supported the drug’s effectiveness in reducing new heterotopic ossification.

Symptoms & Treatment Of FOP

The disease can vary between individuals, but abnormal bone formation can progressively restrict movement. People with FOP may develop difficulty moving their neck, shoulders, spine, hips and other joints as new bone forms around them.

The condition can eventually affect mobility substantially. Extra bone formation can also interfere with everyday activities and contribute to severe disability.

Another characteristic feature is that people with FOP are often born with abnormalities of the big toes, which can help doctors recognise the rare condition early.

Atebrioz is not the first FDA-approved treatment for FOP. The FDA approved Sohonos (palovarotene) in 2023 as the first treatment for the disease.

More recently, the FDA approved Pasatru (garetosmab-grts) in August 2026, making Atebrioz the third FDA-approved treatment for FOP. The newer options differ in how they target the abnormal bone formation.

A confirmed case of mpox has been detected in Bunia, the capital of Ituri province in the Democratic Republic of Congo (DRC), where health authorities are already battling the country's largest-ever Ebola outbreak.

The development has raised concerns about the additional pressure on an already stretched outbreak response and the overall healthcare system.

The mpox case was confirmed after a 21-year-old woman was hospitalised with skin lesions that ae commonly seen in mpox.

The two viruses are not associated with each other, but the threat of two highly infectious diseases is now being navigated in the same area at the same time.

Mpox Case In Congo Amid Ebola Outbreak

Ituri is at the centre of one of the worst Ebola outbreaks the country has ever seen. As of September 23, the DRC reported 7,890 confirmed Ebola cases and around 3,799 deaths. The a case-fatality ratio, according to WHO, stayed put at 48.1%. Ituri, the epicenter of the outbreak, solely accounted for 6,032 confirmed cases.

The Ebola outbreak has also expanded geographically, with new cases reported across 63 health zones in seven provinces. The WHO says the continued spread is increasing the risk of cross-border transmission.

The appearance of mpox in Bunia, against the backdrop of Ebola, creates another challenge for surveillance, testing, infection prevention and safety of healthcare workers.

What Is Mpox?

Mpox is a viral disease that can cause fever, swollen lymph nodes, muscle aches, and peculiar rash or skin lesions. It spreads mainly through close physical contact with an infected person.

Some people recover without complications, while others can develop serious symptoms, particularly those with weak immune systems.

The newly case is especially alarming as the DRC had declared an end to mpox as a national public health emergency in April, following a three-year outbreak that resulted in more than 34,000 confirmed cases nationwide.

Burden On An Already Overwhelmed Healthcare System

The two diseases are caused by different viruses and spread differently. A confirmed mpox case does not indicate that Ebola has mutated or that the two outbreaks are connected.

The WHO says the Ebola response is already operating under difficult conditions, with conflict, insecurity, population displacement and limited access to basic services hampering surveillance, contact tracing, infection prevention and timely care.

The concern is that health systems, that were already dealing with a major outbreak, now have another infection to detect, investigate and contain.

Bunia is not just another location where a case has been detected. It is the capital of Ituri, where the Ebola outbreak is the most concentrated.

WHO teams have described Bunia as a key operational hub for the response, with flights transporting healthcare workers, medicines and other supplies to affected regions.

The immediate priority will be investigation, contact tracing, and surveillance to determine whether the case is linked to a wider cluster.

DRC is already conducting extensive contact monitoring for Ebola. As of September 23, more than 32,000 people were listed for follow-up, depicting the scale of the response.
