Exploring why some athletes perform better than others under stress

Following sleep deprivation, competitive athletes with strong attention control can continue to perform well over time, despite their stress from lack of sleep.

2025-03-31
(Press-News.org) Lack of sleep and stress hinder athletic performance, but some athletes may be better at performing competitively despite sleep issues and stress. In a new JNeurosci paper, researchers led by Yan Sun, from Peking University, looked for predictive behavioral and neural markers in athletes who maintain their performance level following sleep deprivation and under stress. 

The researchers assessed college and professional athletes’ stress levels and cognitive changes after 24 h of sleep deprivation, then followed their competitive performances for up to 2 months. Increased anxiety and stress hormone levels from lack of sleep did not predict athletic performance in competitions. However, how much control athletes had over their attention could predict how at risk they were for worsened athletic performance. The researchers also identified a brain signal involved in impaired attentional control from sleep deprivation that could potentially predict worsened athletic performance. 

According to the authors, this work suggests that overnight sleep deprivation is a stressor that those with stronger attentional control may be more easily able to overcome as they perform over time. According to Sun, “Cognitive predictors after sleep deprivation could help athletes and coaches to monitor training states, manage stress more effectively to enhance performance, or adjust athlete participation arrangements.”

Exploring binge eating and binge drinking alcohol comorbidity

2025-03-31
The comorbidity of binge eating and alcohol binge drinking is prevalent and increases the risk of other neuropsychiatric and bodily conditions. However, the mechanisms linking these forms of binge consumption are unclear. To explore the link between binge eating and binge drinking alcohol, Karen Szumlinski, from the University of California, Santa Barbara, and colleagues developed a way to model the disease comorbidity in mice. As reported in their JNeurosci paper, this mouse model led to the discovery that females with a history of binge eating start binge drinking ...

The proportion of harmful substances in particulate matter is much higher than assumed

2025-03-31
People breathing contaminated air over the course of years are at greater risk of developing numerous diseases. This is thought to be due to highly reactive components in particulate matter, which affect biological processes in the body. However, researchers from the University of Basel, Switzerland, have now shown that precisely these components disappear within hours and that previous measurements therefore completely underestimate the quantities in which they are present. From chronic respiratory problems to cardiovascular diseases, ...

Administration is weakening U.S. research capacity and endangering Americans, nation’s leading scientists warn

2025-03-31
The wellbeing of Americans and the country’s longstanding position as a world leader in science and technology are in jeopardy due to the actions of the Trump administration, approximately 1,900 leading figures in medicine, science, and engineering warn today in an open statement to the American public. The list of signatories includes Nobel Prize winners, deans of medical schools, and national leaders in science and technology. “For over 80 years, wise investments by the US government have built up the nation’s research enterprise, making it the envy of ...

Trade Tariffs on Canadian Pharmaceuticals— Implications for US Drug Supply and Costs

2025-03-31
About The Study: Although Canada is not the largest supplier of medications to the U.S., tariffs could raise costs and strain supply chains. This study estimates that $3 billion in U.S. pharmaceuticals depend on Canadian manufacturing, with 25% tariffs adding $750 million in cost. Although the Inflation Reduction Act provisions limit cost pass-through to some payers (i.e., Medicare), manufacturers may still adjust production or alter distribution, increasing supply chain fragility.

Cardiovascular Health Among Rural and Urban US Adults— Healthcare, Lifestyle, and Social Factors

2025-03-31
About The Study: This national cross-sectional study found substantial rural-urban disparities in cardiometabolic risk factors and cardiovascular diseases, which were largest among younger adults and almost entirely explained by social risk factors. These findings suggest that efforts to improve socioeconomic conditions in rural communities may be critical to address the rural-urban gap in cardiovascular health.

Study finds gap between heart disease outcomes in men and women has narrowed over past 20 years

Study finds gap between heart disease outcomes in men and women has narrowed over past 20 years
2025-03-31
While the typical image of someone suffering a heart attack might be a man clutching his chest, heart disease is a major problem for women, too. In fact, it’s the leading cause of death among women in the United States, with nearly 45% of the nation’s women over age 20 living with some form of cardiovascular disease. A new study from heart researchers at Intermountain Health in Salt Lake City shows that while rates of death and other cardiac-related events – like heart attack ­– are still high for women, the ...

New study links lower proportions of certain sleep stages to brain changes associated with Alzheimer’s disease

2025-03-31
DARIEN, IL — New research reveals that lower proportions of specific sleep stages are associated with reduced brain volume in regions vulnerable to the development of Alzheimer’s disease over time. Results show that individuals with lower proportions of time spent in slow wave sleep and rapid eye movement sleep had smaller volumes in critical brain regions, particularly the inferior parietal region, which is known to undergo early structural changes in Alzheimer’s disease. The results were adjusted for potential confounders including demographic characteristics, smoking history, alcohol use, hypertension, and coronary heart disease. “Our findings provide ...

Long-term practice of Transcendental Meditation may reduce both stress and aging

Long-term practice of Transcendental Meditation may reduce both stress and aging
2025-03-31
A collaborative study conducted by researchers at Maharishi International University (MIU), the University of Siegen, and the Uniformed Services University of the Health Sciences reveals that individuals practicing Transcendental Meditation® (TM®) technologies long-term show favorable biological markers of aging and stress. The research compared gene expression, cognitive function (via EEG), and hair glucocorticoids (cortisol and cortisone) in 12-year and 40-year TM groups and non-meditator controls. “This study provides evidence that long-term practice of TM technologies has a broad range of health benefits at the molecular ...

Delicate balancing act determines how many genome gateways form in cells

Delicate balancing act determines how many genome gateways form in cells
2025-03-31
EMBARGOED UNTIL MONDAY, MARCH 31 – 11:00 AM Eastern The nuclei in our cells are miniature warehouses safeguarding the genetic blueprint for the body’s biologic machinery. As warehouses go, nuclei are more like libraries than bank vaults. Too many cellular components need access to the genome to lock it down like Fort Knox. Instead, large groupings of more than 1,000 individual protein molecules called nuclear pore complexes (NPCs) pepper the dividing membrane, serving as gateways for materials and messages entering and exiting the nucleus. While the basic need for this shuttle service is constant, ...

Postpartum hormonal contraceptive use and risk of depression

2025-03-31
About The Study: Hormonal contraceptive initiation postpartum was associated with an instantaneous increased risk of developing depression in this cohort study. The associated risk was higher the earlier it was initiated postpartum, at least for combined oral contraceptives. This finding raises the issue of whether the incidence of depression postpartum is increased by routine hormonal contraceptive initiation after childbirth.
