Loneliness grows as we age

A new study found that loneliness grows as people age, with a U-shaped pattern of higher levels in younger and older adulthood. Factors associated with persistent loneliness include social isolation, lower education, income, and functional limitations, as well as being divorced or widowed, a smoker, or having poorer health.

Listening to mindfulness audios during radiation improves physical, emotional side effects

Men with prostate cancer who listened to mindfulness audio recordings during radiation therapy experienced significant reductions in fatigue, sleep problems, anxiety, and depressive symptoms. The study found that the mindfulness intervention was more effective than listening to relaxing music during treatment.

Longer genes are linked to aging

Four studies conclude that longer genes are most susceptible to aging due to increased potential sites for DNA damage. Long genes have more sites for damage, making them prone to degradation with age, contributing to conditions like Alzheimer's disease.

U.S. maternal death rate increasing at an alarming rate

A new study from Northwestern Medicine found that the US maternal mortality rate increased by nearly doubling between 2014 and 2021, with no correlation to increasing pregnancy-related deaths among older adults. The study highlights the need to investigate other causes of maternal mortality, particularly cardiovascular disease.

How ketamine acts fast and slow

Researchers discovered that ketamine's sustained effects involve increasing immature cells' activity, while rapid effects rely on newborn neurons firing more rapidly. This breakthrough opens doors to developing new antidepressant treatments.

Outsmarting chemo-resistant ovarian cancer

Researchers have discovered a new way to target chemotherapy-resistant ovarian cancer cells by depriving them of cholesterol, leading to significant tumor growth reduction. The nanoparticles starve the cells of cholesterol, triggering cell death through oxidation of lipids in the cell membrane.

Reducing harmful health screenings and overtreatment in older adults

Researchers at Northwestern University found a significant decrease in screenings for prostate cancer and urinary tract infections after implementing point-of-care alerts. The study showed a 9% reduction in PSA screenings and a 5.5% reduction in urine testing, with minimal changes in overtreatment of blood sugar.

Understanding how soil traps carbon

Researchers found that electrostatic charges, structural features of carbon molecules, and surrounding metal nutrients play major roles in soil's ability to trap carbon. The study aims to help predict which soil chemistries are most favorable for trapping carbon.

Allergic reactions prevented with decorated nanoparticles

Scientists have created a new therapy using nanoparticles to target specific immune cells responsible for allergic responses. The approach, which combines an allergen with antibodies that selectively inhibit mast cells, has shown promising results in a mouse study, preventing allergic reactions without causing side effects.

Cut salt, cut blood pressure

A new study from Northwestern University and Vanderbilt University Medical Center found that reducing sodium intake by just one teaspoon a day can lower systolic blood pressure by about 6 millimeters of mercury, comparable to the effect produced by commonly used first-line medication for high blood pressure. The study involved middle-a...

Yucatán’s underwater caves host diverse microbial communities

Researchers constructed the most complete map yet of the microbial communities in Yucatán's underwater caves, revealing distinct patterns and a core set of organisms performing key roles. The study found that Comamonadaceae, a family of bacteria typically found in groundwater systems, lived in several niches across the cave system.

Communities of color suffer disproportionately higher pollution-related deaths

A new Northwestern University study estimates that approximately 171,000 premature deaths per year are linked to nitrogen dioxide (NO2) exposure, with a disproportionate number occurring in marginalized communities. The study found that NO2 pollution affects predominantly Black census tracts 47% higher than the national average.
