Mothers' relationships can influence adolescent children's relationships, MU study finds

A new study from the University of Missouri suggests that mothers' friendships with other adults can impact their adolescent children's relationships with their own friends. Mothers who display high levels of conflict with friends may signal to their children that such behavior is acceptable, leading to anxiety and depression.

Lower education levels linked to unhealthy diets

Research found that adults with lower education levels consumed more sugar- and fat-rich foods than those with higher education levels. They also expended more energy through physical activity, which may explain their higher food intake.

Drilling for hydrocarbons can impact aquatic life

A new study published in PLOS ONE found that drilling sumps associated with hydrocarbon extraction can negatively impact aquatic ecosystems. The degradation of these sumps can lead to changes in the community composition of zooplankton, highlighting the need for better climate change mitigation strategies.

Hospitals with neurology residency programs more likely to administer life-saving clot-busting drugs

Stroke patients treated at hospitals with neurology residency programs are significantly more likely to receive life-saving clot-busting drugs than those seen at other teaching or non-teaching hospitals. The findings suggest that having a neurologist on hand 24/7 increases the chances of better outcomes and improves treatment adherence.

Prognostic value of baseline HRQOL for survival for 11 types of cancer pointed out by EORTC study

The EORTC study found that baseline recorded health-related quality of life parameters provided additional prognostic information for survival in eleven types of cancer, including brain, breast, and colorectal cancers. The specific health-related quality of life parameters found to be predictive for survival varied by cancer site.

Hormone levels in women using contraception affect nerve activity involved in vessel constriction

Research finds that hormone contraception affects the regulation of muscle sympathetic nerve activity differently, depending on sex hormone levels and chemoreflex stress. Hormone levels influence the frequency and amplitude of nerve firings, with higher hormone levels protecting against cardiovascular damage in younger women.

Breakthrough by Temple researchers could lead to new treatment for heart attack

Researchers at Temple University have discovered that inhibiting a specific protein called TNNI3K can limit damage from heart attacks and protect the heart from further injury. The findings have significant potential for translation into human patients and could lead to the development of a new treatment using a TNNI3K inhibitor.

Staying alive in the high and dry

Researchers discover that desert plants use hydraulic lift to acquire nutrients in dry conditions, supporting plant productivity and seed set. The system relies on tiny amounts of water released from plant roots into dry soil at night.

How does electrical stimulation modulate electrophysiological environment after SCI?

Researchers from the Chinese Academy of Sciences found that electrical stimulation with a reversed polarity can effectively modulate injury potentials and promote the spontaneous repair of cell membranes in rats with spinal cord injuries. This study proposes a method to define stimulation intensity based on injury potential values.

Intervention does not improve depression symptoms

A study found that targeted communication strategies did not improve mental health outcomes in patients with depression. The interventions increased patient engagement and requests for information about depression, but failed to improve symptoms at a 12-week follow-up.

Considerable gender, racial and sexuality differences in attitudes toward bisexuality

A study found considerable gender, racial, and sexuality differences in attitudes toward bisexuality, with women, white people, and those identifying as lesbian or bisexual showing less bias.

VC predicts the motion of the ocean

Research led by ANU Vice-Chancellor Professor Ian Young uses satellite data to track wave decay and develop a mathematical formula for predicting swell action. The study provides comprehensive data on the rate of decay, which will increase the accuracy of wave predictions for industries such as shipping and surfing.
