Microplastics may pose a risk to brain health, study suggests

Microplastics could be damaging the brain in multiple ways, according to new research from the University of Technology Sydney. Scientists have identified five key pathways through which these tiny plastic particles may affect neurological health, raising concerns about their long-term impact. These include triggering immune cell activity, generating oxidative stress, disrupting the blood–brain barrier, impairing mitochondria and damaging neurons.

These processes are associated with neurodegenerative conditions such as Alzheimer’s and Parkinson’s disease, although more research is needed to fully understand the link. As a result, the researchers are recommending that people take steps to reduce their microplastic exposure. Research team member Dr Keshav Raj Paudel said: “We need to change our habits and use less plastic. Steer clear of plastic containers and plastic cutting boards, don’t use the dryer, choose natural fibres instead of synthetic ones and eat less processed and packaged foods.” The findings were published in Molecular and Cellular Biochemistry.

Veganuary celebrates record numbers

A record 30 million people worldwide took part in Veganuary 2026, reinforcing the campaign’s growing global impact. The annual initiative, which encourages people to try a vegan lifestyle in January, also saw at least 1,187 new plant-based products and menu items launched globally.

More than 270 organisations joined the Workplace Challenge, while social media content reached 157 million views. Campaigns expanded into Iceland and Ireland, alongside strong engagement across Europe, the US, India and Latin America. Veganuary CEO Wendy Matthews said the results highlight a “lasting cultural shift” towards more conscious food choices, rather than a passing trend.

Back pain “dismissed” despite long-term impact

A new UK survey has revealed that many people living with chronic back pain feel their condition is not taken seriously. The research found that 88% of respondents had experienced back pain for more than a year, with 37% suffering for over a decade. Despite this, 74% said their pain is often downplayed by family, friends or employers, and 69% feel pressure to “push through” discomfort.

Osteopath Michael Fatica, co-founder of the online back rehabilitation programme Back in Shape, which conducted the survey among its patients, said these findings reflect a deeply ingrained cultural misunderstanding around back pain. He said: “With the right approach, many cases can be mitigated or even prevented. Strength-based exercise, alongside good nutrition and healthy daily habits, is crucial for building resilience and protecting the spine.” For more information, including expert advice, videos and podcasts related to back health and rehabilitation, visit www.backinshapeprogram.com

Island birds reveal gut–immune health link

A new study from the University of East Anglia has uncovered a surprising link between gut health and the immune system, using a small island bird as a model. Researchers studying Seychelles warblers found that immune genes help to determine which beneficial bacteria live in the gut.

By analysing faecal samples from birds on Cousin Island, scientists showed that variation in key immune genes is closely linked to both the composition and function of the gut microbiome. Researcher Dr Chuen Zhang Lee said: “Our work suggests a two-way relationship. Immune genes influence the gut microbiome, and the microbiome feeds back to influence immune function.” The researchers say that similar processes are likely to occur in humans, offering new insights into gut health and disease. The findings were published in the journal Microbiome.
