Lithium study yields insights in the fight against HIV

admin — Wed, 21 Jan 2026 15:07:00 +0000

Lithium, a widely used treatment for bipolar disorder and other mood disorders, has shown early promise in suppressing HIV, �鶹��ý��վ researchers report.

A new study published in iScience found lithium can prevent infected cells from reactivating, and that it does so through an unexpected biological mechanism.

The findings point toward future treatments designed to mimic lithium’s beneficial effects while avoiding its broader impacts on the body.

Freshwater browning threatens growth and populations of economically important fish, �鶹��ý��վ researchers say

admin — Mon, 19 Jan 2026 15:30:53 +0000

Freshwater browning is stunting fish growth of some species, shrinking populations of others and changing the composition of fish communities, �鶹��ý��վ-led research suggests. “Browning” refers to freshwater bodies turning tea-coloured, a phenomenon driven by higher levels of dissolved organic matter and/or higher levels of iron in the water. Causes include changes in land use and climate, and reduced acid precipitation.

The findings indicate that changes in land use and climate are affecting biodiversity and how ecosystems function, with implications for fisheries management.

Irradiated cannabis might still harbour toxic fungi and residues, �鶹��ý��վ study finds

admin — Thu, 15 Jan 2026 16:16:56 +0000

Gamma irradiation, an industry-standard sterilization method for medicinal and recreational cannabis, does not fully eliminate toxic fungi or their chemical residues, a �鶹��ý��վ study has found. Current testing practices may also miss contamination, raising concerns about health risks for vulnerable users, particularly those with weakened immune systems.

Findings suggest that certain medications for Type 2 diabetes reduce risk of dementia

admin — Thu, 15 Jan 2026 14:02:20 +0000

A large �鶹��ý��վ study has found that two classes of medications commonly prescribed for Type 2 diabetes, both incretin-based, are associated with a reduced risk of dementia.

Drawing on clinical data from more than 450,000 patients, the research adds to growing evidence that incretin-based therapies have protective benefits for the brain.

The study examined GLP-1 receptor agonists, which include such medications as Ozempic, as well as DPP-4 inhibitors.

Expert: Global call to scale up needle and syringe programs

Urgent action is needed to scale up needle and syringe programs around the world to curb the spread of HIV and hepatitis C, an international group of experts warns.

In a new study published in The Lancet Global Health, the authors say the programs are effective but remain widely underfunded due to policy barriers rooted in stigma and discrimination.

�鶹��ý��վ researcher unveils new model that more accurately measures greenhouse gas emissions from natural gas

admin — Fri, 09 Jan 2026 14:07:07 +0000

�鶹��ý��վ engineering researchers have introduced an open-source model that makes it easier for experts and non-experts alike to evaluate greenhouse gas emissions from U.S. natural gas supply chains and yields more accurate results.

Lead author Sarah Jordaan, an associate professor in �鶹��ý��վ’s Department of Civil Engineering, said the work, published in Cell Reports Sustainability, responds to a long-standing challenge.
