ɬ�﷬ — Mon, 23 Feb 2026 14:46:40 +0000

A new ɬ�﷬ study has found a direct link between age‑related declines in neuron activity in the cerebellum and worsening motor skills, including gait, balance and agility. While it is well known that these abilities diminish with age, this is the first research to pinpoint how changes in Purkinje cells – a key type of cerebellar neuron – drive this decline and translate into measurable changes in behaviour and physical function.

Colourism might help explain health inequities suffered by dark-skinned Black Americans, researchers say

ɬ�﷬ — Thu, 19 Feb 2026 19:24:38 +0000

A study of Black Americans is among the first to show how the internalization of negative messages about dark skin tones could be linked to harms to health.

Researchers found that Black Americans who are, or perceive themselves to be, dark skinned show clear markers of cellular aging associated with immune-system damage and also score lower on a measurement of self-worth. Cellular aging and low self-worth are both associated with relatively poor health outcomes.

Plants retain a ‘genetic memory’ of past population crashes, study shows

ɬ�﷬ — Thu, 12 Feb 2026 14:32:55 +0000

Researchers at ɬ�﷬ and the United States Forest Service have found that plants living in areas where human activity has caused population crashes carry long-lasting genetic traces of that history, such as reduced genetic diversity. Because genetic diversity helps species adapt to climate change, disease and other stresses, the study suggests it is vital to consider a population’s history-influenced genetics alongside its size and habitat in conservation planning.

Economic, educational and gender inequities can contribute to problematic social media use among teens, findings suggest

ɬ�﷬ — Wed, 11 Feb 2026 20:42:44 +0000

A new ɬ�﷬ study suggests that problematic social media use among teens is in part related to broader social inequalities.

Zékai Lu, a PhD student in ɬ�﷬’s Department of Sociology and author of the study, had set out to determine whether problematic social media use is driven mainly by individual traits or whether the social environment of the country a teen lives in also plays a significant role.

People can learn to reject unfair advantages, even when it costs them

ɬ�﷬ — Wed, 11 Feb 2026 15:32:11 +0000

A new study co-authored by ɬ�﷬ researchers suggests people can be taught to reject unfair advantages.

“We often benefit personally from an unequal distribution of resources, a phenomenon known as advantageous inequity – for example, receiving a higher salary than a colleague with the identical role,” said senior author Ross Otto, a psychology professor. “Here we ask whether people can learn to punish advantageous inequity merely by observing the inequity-averse preferences of another person.”

Addressing shame should be a focal point of treatment of childhood sexual abuse survivors, researchers suggest

ɬ�﷬ — Tue, 10 Feb 2026 14:43:35 +0000

A ɬ�﷬-led study on the role played by shame in the continuing trauma suffered by survivors of childhood sexual abuse indicates that addressing shame should be a focal point of treatment. Clinicians should use strategies that normalize disclosure, validate survivors’ feelings and integrate shame-resolution techniques into their therapy plans, the researchers suggested.

Study suggests protein made in the liver is a key factor in men’s bone health

ɬ�﷬ — Thu, 05 Feb 2026 14:01:37 +0000

New research suggests the liver plays a previously unrecognized role in bone health, but only in males.

A ɬ�﷬-led study published in Matrix Biology found that a protein made in the liver helps regulate bone growth in male mice, but not in females. The findings may help explain why men with liver disease are more likely to experience bone loss.

ɬ�﷬ researchers develop quick test that stands to curb antimicrobial resistance

ɬ�﷬ — Wed, 04 Feb 2026 14:48:47 +0000

ɬ�﷬ researchers have developed a diagnostic system capable of identifying bacteria –and determining which antibiotics can stop them – in just 36 minutes, a major advance in the global effort to curb antimicrobial resistance (AMR). Current clinical testing methods typically take 48 to 72 hours, leaving physicians without timely guidance.

The researchers say this innovation arrives at a critical moment due to the urgency of the AMR crisis, which arises from bacteria developing resistance to antibiotics.

Freshwater browning threatens growth and populations of economically important fish, ɬ�﷬ researchers say

ɬ�﷬ — 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, ɬ�﷬-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, ɬ�﷬ study finds

ɬ�﷬ — Thu, 15 Jan 2026 16:16:56 +0000
