Scientists use fossils to assess the health of Florida’s largest remaining seagrass bed. Surprisingly, it’s doing well!

A new study published in Marine Ecology Progress Series reveals that seagrass ecosystems along Florida's Nature Coast have remained relatively healthy over the last several thousand years. The research, conducted by conservation paleobiologists, used fossilized mollusk shells to infer ecosystem health and found that these communities a...

Older adults are getting infected with HIV, but prevention focuses on young people

A study published in The Lancet Healthy Longevity reveals that older adults in sub-Saharan Africa are at risk of HIV infection, particularly those who have experienced social stigma and lack access to education. Interventions such as repeated testing, PrEP, and awareness campaigns can help reduce infections among the elderly.

The effect of physical fitness on mortality is overestimated

A new study from Uppsala University found that people with high fitness levels in late adolescence have a lower risk of dying prematurely, but the association between physical fitness and reduced mortality risk may be overstated. The researchers examined data from over 1 million Swedish men and found no significant difference in the ri...

Study reveals why women tend to have faster heartbeats, men more irregular rhythms

Researchers at Ohio State University discovered that women's hearts beat faster due to higher levels of genes like TBX3 and HCN1. In contrast, men's hearts are more prone to irregular rhythms like atrial fibrillation, linked to inflammation and collagen production.

Study reveals a deep brain region that links the senses

A new Yale-led study indicates that multiple senses stimulate a critical region deep in the brain controlling consciousness. The research found that sensory input uses shared subcortical systems and that all input stimulates activity in two deep brain regions, even when subjects are sharply focused on specific senses.

New study reveals how to reclaim space for civil society in times of democratic decline

A new study finds that emphasizing widely supported public service efforts and redefining what it means to be part of a group can increase the perceived legitimacy of controversial civil organizations. The research tested different messaging strategies on over 1,600 Jewish Israeli participants, using real-world examples from a delegiti...

Seeing well-designed gardens could relax us almost immediately because we look at them differently

A team of researchers investigated the impact of Kyoto's Murin-an garden on viewers' relaxation. They found a correlation between rapid gaze shifts and reduced stress levels. The design features of the well-crafted Japanese garden led to frequent, rapid horizontal shifts in gaze, which induced a calming effect.

USC study reveals link between type 2 diabetes and brain health in older adults from various populations

A new USC-led study found a significant link between type 2 diabetes and cortical thickness in older adults from various populations. The researchers discovered that individuals with T2DM exhibited thinner cortex, particularly in temporal and parietal regions critical for memory and cognitive function.

USC researchers develop low-cost blood test for early Alzheimer’s detection

Researchers from USC Keck School of Medicine have developed a low-cost blood test that detects five biomarkers of Alzheimer's disease, including amyloid and tau proteins. The test uses xMAP technology and has the potential to catch the disease in its earliest stages, when treatment might be able to prevent or delay cognitive decline.
