Fungal superhighway and the hidden fungal world beneath our feet revealed
Underground fungi network and mycorrhizal networks mapped across 110 quadrillion kilometers of Earth’s soils
Discover how this forest underground network—the wood wide web—moves carbon, water, and nutrients while shaping climate and ecosystems
What You'll Learn:
How mycorrhizal networks form a global fungal superhighway connecting roots, soils, and entire ecosystems
Why a single teaspoon of healthy soil can hold up to 100 meters of 5 µm-wide fungal hyphae—and what that means for soil health
How a 110 quadrillion kilometer underground fungi network compares to 724 astronomical units and a Solar System-spanning scale
The role of soil fungi in moving an estimated 4 billion tons of carbon dioxide into soils each year
How fungi and climate change are linked through carbon storage in soil and underground nutrient cycling
Why some estimates suggest fungal networks may channel 13 gigatons of water to plants annually—and why that number still needs verification
How the newly mapped hidden fungal world could transform conservation, reforestation, and regenerative agriculture strategies
Practical ways scientists and land stewards might protect and restore the wood wide web to build climate resilience

Episode about Prenatal health and early diet may shape fatty liver risk, study suggests
Research completed for: Prenatal health and early diet may shape fatty liver risk, study suggests
Key Findings:
Emerging evidence shows that the roots of non-alcoholic fatty liver disease (NAFLD) can be traced back to the womb and the first years of life. Maternal obesity, gestational diabetes, nutrient imbalances, and the infant’s post-natal diet appear to ‘program’ liver metabolism through hormonal, epigenetic and microbiome-mediated pathways. Children exposed to these factors have a measurably higher liver‐fat fraction and a greater likelihood of developing NAFLD and its complications later in life.

Episode about Written exposure therapy can provide transformative, scalable PTSD care
Research completed for: Written exposure therapy can provide transformative, scalable PTSD care
Key Findings:
Written Exposure Therapy is a brief, five-session, structured writing intervention that repeatedly exposes individuals to the memory of their trauma on paper. In randomized controlled trials (RCTs), WET has shown PTSD symptom reductions comparable to gold-standard treatments such as Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE), but with far fewer therapy hours, lower dropout rates, and minimal clinician training requirements—making it highly scalable for health systems that fac

Research completed for: The frontier of women's health care innovation
Key Findings:
FemTech—technology-enabled products and services that focus on women’s biological and social health needs—has moved from niche period-tracking apps a decade ago to a diversified, evidence-backed sector spanning AI-powered diagnostics, wearables, tele-gynecology, and menopause care. Driven by long-standing research gaps, smartphone ubiquity, and rising investment, FemTech generated an estimated US$2.5 billion in venture funding in 2021 alone and is projected to reach a global market size of US$10

Episode about Most Australians with dementia excluded from voluntary assisted dying, study finds
Research completed for: Most Australians with dementia excluded from voluntary assisted dying, study finds
Key Findings:
A 2024 University of Southern Queensland study led by Prof. Kerstin Braun shows that 70–80 % of Australians who will develop dementia would not meet the legal criteria for voluntary assisted dying in any state or territory, primarily because every Australian VAD statute requires the person to have decision-making capacity both when they request and when they receive the life-ending medication. Dementia’s progressive cognitive decline means that, by the time symptoms are severe enough to satisfy

Episode about Popular joint supplement glucosamine linked to faster Alzheimer’s progression
Research completed for: Popular joint supplement glucosamine linked to faster Alzheimer’s progression
Key Findings:
A large longitudinal cohort analysis involving older adults with mild cognitive impairment (MCI) reported that people who regularly took over-the-counter glucosamine were about 25 % more likely to convert to Alzheimer’s disease (AD) during the study period than non-users. Biomarker sub-studies showed higher levels of advanced glycation end-products and impaired insulin-signalling markers in cerebrospinal fluid among glucosamine users, suggesting a plausible biological pathway. The results do not

Alcohol and health risks: new science on daily drinking and mortality
Fresh moderate drinking study challenges old rules on alcohol cancer risk and heart disease
Understand how the science of alcohol consumption applies to your “one drink a day” habit—and what to do this week
What You'll Learn:
Why new research shows that daily or “moderate” drinking isn’t automatically harmless—even if you stay under old guidelines
How the latest moderate drinking study from the Journal of Studies on Alcohol and Drugs links daily drinking and mortality, disability, and disease
What current science actually says about alcohol and heart disease versus cancer, and why the “protective” narrative is fading
A simple way to map out what a normal week of drinking really looks like for you (and why we often underestimate)
How to experiment with “one less drink” without feeling deprived or losing your social identity
Specific health effects of alcohol on sleep, mood, focus, and long-term brain and body health you can watch for in just one week
Practical strategies to lower the risks of daily alcohol use—even if you don’t want to quit completely
Questions to discuss with your doctor about alcohol and health risks, based on the newest science of alcohol consumption

Episode about Early-onset breast cancer in Black women links most often to BRCA1 and BRCA2 variants
Research completed for: Early-onset breast cancer in Black women links most often to BRCA1 and BRCA2 variants
Key Findings:
Large cohort studies—including a 2023 paper in Cancer that sequenced 5,000 Black women diagnosed with breast cancer before age 50—show that pathogenic variants in the tumor-suppressor genes BRCA1 and BRCA2 account for the single largest share of inherited risk in this group (≈10–12% carry a harmful variant, double the rate seen in same-age Black controls and somewhat higher than in White counterparts). Because BRCA1/2 mutations disable DNA-repair pathways, carriers tend to develop aggressive, of

Episode about Infections are major 'health hazard' for people with diabetes
Research completed for: Infections are major 'health hazard' for people with diabetes
Key Findings:
People with diabetes face a markedly higher risk of contracting infections, experiencing severe courses, being hospitalized, and dying from infectious diseases than people without diabetes—even after adjusting for age, sex, and other comorbidities. Hyperglycaemia impairs several arms of the innate and adaptive immune system, creates a favourable environment for microbial growth, and contributes to vascular and neuropathic complications that further increase susceptibility (e.g., diabetic foot ul

Episode about Scientists recreate enterovirus infection in a new model of the human intestine
Research completed for: Scientists recreate enterovirus infection in a new model of the human intestine
Key Findings:
Researchers at the University of Tokyo have built a miniaturized ‘intestine-on-a-chip’ that faithfully mimics the structure, mucus layer, and peristaltic motion of the human gut. Using the system, the team maintained a productive, weeks-long infection with enterovirus A71 (EV-A71) and observed that the virus exploits the epithelial turnover of the gut to spread while dampening interferon-based immune signaling. The platform therefore offers an ethically sound, highly controllable alternative to
