A ‘smoke-free generation’ in Canada? New analysis says it would result in vast health gains, healthcare cost savings

A new analysis suggests that implementing a lifetime ban on tobacco products for individuals born after 2009 would result in vast health benefits and healthcare cost savings. The study estimates $2.3 billion less in healthcare costs and 476,814 more quality-adjusted life years for Canadians over a 50-year timespan.

Songbirds socialize on the wing during migration, new study says

Researchers have found evidence of songbirds forming social connections and potentially exchanging information about their migration routes through vocalizations. The study suggests that social cues play a significant role in shaping migration behaviors, particularly for young birds learning from observing other birds.

Trastuzumab emtansine improves long-term survival in HER2 breast cancer

The phase 3 KATHERINE clinical trial found trastuzumab emtansine to be an effective adjuvant treatment for high-risk HER2-positive breast cancer patients, reducing the risk of death or invasive disease by 46% and improving survival. The study showed consistent benefits across patient subgroups, supporting T-DM1 as a new standard of care.

COVID-19 infection associated with nearly eightfold increase in chronic fatigue syndrome

A new study published in the Journal of General Internal Medicine found that COVID-19 infection significantly increases the rate of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) among COVID-19 survivors. Nearly eight times more people with ME/CFS were infected with SARS-CoV-2 than those without, according to the research.

Diversified cropping systems boost nitrogen supply but not soil carbon, study finds

A new study has found that diversified cropping systems can increase nitrogen supply in the soil, but do not lead to increased soil carbon levels. The study, published in Nature Sustainability, used stable carbon isotopes to analyze soil core emissions and found that decomposition rates were higher in longer rotations.

DARPA-ABC program supports Wyss Institute-led collaboration toward deeper understanding of anesthesia and safe drugs enabling anesthesia without the need for extensive monitoring

A multidisciplinary team led by the Wyss Institute aims to create novel anesthesia-inducing drugs that can safely induce an anesthesia-like state without compromising vital functions. The project leverages expertise from Harvard's MCB, MIT, and Tufts University to develop safe battlefield-ready anesthetics.

Indigenous students face cumbersome barriers to attaining post-secondary education

A study by the University of Toronto found that Indigenous university students struggle with funding, affordable housing, and childcare, leading to feelings of isolation and decreased sense of belonging. Resource centers, cultural events, and mentorship opportunities can help mitigate these barriers.
