When the workload on the heart increases, the ventricular wall may thicken too, known as cardiac hypertrophy. This is an adaptive response that reduces pressure on the heart and maintains the activity of this vital organ. It is often a reversible process that does not cause serious effects on the structure or function of the heart, but if the factor causing cardiac overload becomes chronic, it can lead to pathological hypertrophy with more serious effects (dilatation of the ventricular cavities, alterations in cardiac function, heart failure, etc.). People with diabetes — specially type 2 diabetes (DM2) — are at increased risk ...

Acute coronary syndrome (ACS) in patients with SARS-CoV-2 infection represents a critical intersection of viral-induced inflammation and cardiovascular pathology. This review explores the dual mechanisms driving SARS-CoV-2-associated ACS and evaluates emerging therapeutic strategies, including phytomedicine and nanotechnology, to address both viral and cardiovascular complications. SARS-CoV-2 and ACS Pathogenesis SARS-CoV-2 infection exacerbates ACS through systemic inflammation, endothelial dysfunction, and plaque destabilization.

NEW ORLEANS, May 22, 2025 – Coral reefs are vital to marine biodiversity, but their livelihood is under threat due to climate instability and the impacts of human activities. Rehabilitating marine environments requires innovative solutions. Océane Boulais, a doctoral student at the Scripps Institution of Oceanography, studies one of these potential solutions: the impacts of acoustics on coral larval recruitment and settlement. After spawning, coral larvae drift or swim through the water column, seeking suitable sites to find a home to attach to along the ocean floor. “Multiple chemical compounds have already been identified as ...

Women who choose to stop treatment during pregnancy and breastfeeding are putting their health at risk, and have to weigh their desire to have children and breastfeed against a risk that we know very little about. In two ongoing clinical trials, researchers establish a new standard for human lactation studies that includes sampling of breast milk and plasma from both mothers  and breastfed infants.  “The lack of scientific evidence is an ethical problem for women and doctors, considering that around 70 percent of women need to use medicines sometime during their pregnancy. In many cases, women are recommended ...

Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision goggles, the contact lenses, described in the Cell Press journal Cell on May 22, do not require a power source—and they enable the wearer to perceive multiple infrared wavelengths. Because they’re transparent, users can see both infrared and visible light simultaneously, though infrared vision ...

Ammonia released from penguin guano may help to reduce the effects of climate change in the Antarctic by contributing to increased cloud formation, according to an analysis published in Communications Earth & Environment. The conclusion is the result of measurements taken downwind of a colony of Adelie penguins (Pygoscelis adeliae). Antarctic ecosystems are facing significant pressures because of human-driven climate change, including a recent decreasing trend in the area covered by sea ice. Penguins are key species in the Antarctic ecosystem whose habitat is threatened by this ongoing ice loss. They are also, along with other ...

Key Findings Women living in neighborhoods with high vulnerability had a higher risk of earlier natural menopause onset, primarily due to socioeconomic status and household conditions. No significant association was found between neighborhood disadvantage and the severity of menopause symptoms. Boston, MA – A new study led by the Harvard Pilgrim Health Care Institute highlights the significant impact of living in disadvantaged neighborhoods on the onset of menopause. The research followed 691 women from pregnancy to midlife and found that those residing in highly vulnerable neighborhoods, particularly within 10 years of perimenopause onset, experienced menopause approximately two ...

About The Study: In this cross-sectional study, 1 in 10 patients hospitalized for respiratory syncytial virus (RSV) had a concurrent acute cardiovascular event. Odds of cardiac events were significantly higher in RSV vs COVID-19 hospitalizations in both vaccine-boosted and unboosted individuals. In contemporaneous hospitalizations for RSV or influenza after the pandemic (2023-2024), odds of heart failure were significantly higher in RSV hospitalizations vs vaccine-breakthrough influenza hospitalizations. These findings suggest that patients with preexisting cardiovascular risk should consider vaccination ...

Radboudumc researchers Kirsten van Abeelen, Edwin Ardiansyah, Sofiati Dian, Vinod Kumar, Reinout van Crevel and Arjan van Laarhoven used metabolomics to study cerebrospinal fluid (CSF) samples from tuberculous meningitis patients in Vietnam and Indonesia, with long-standing collaborators from Bandung and Jakarta (Indonesia), the Broad Institute (Boston) and the Oxford University Research Unit in Ho Chi Minh City (Vietnam).   Meningitis is the most severe form of tuberculosis. Damaging inflammation contributes to its poor prognosis. Corticosteroids reduce mortality, but ...

Not all children grow the same way. A new study from the Environmental influences on Child Health Outcomes (ECHO) Program suggests that body weight changes in early childhood may be associated with later obesity risk. Funded by the National Institutes of Health (NIH), the study tracked children’s body mass index (BMI) from infancy through age 9 and found two distinct growth patterns. Most children followed a typical curve, with BMI decreasing in early childhood before gradually rising again. But a smaller group followed a trajectory marked by a sharp rise in BMI, ...

Key Takeaways  Helmet laws work (when they’re universal): Motorcycle riders in North Carolina (with a universal helmet law) wore a helmet 94% of the time compared with 47% of riders in South Carolina (partial law).   Helmets mean less severe injuries: Motorcyclists who wore helmets were less likely to die or require intensive care after an accident.  Lost progress: Helmet laws have been rolled back in many states resulting in only 19 states now having universal helmet laws.  CHICAGO — New ...

A potentially lifesaving new smartphone app can help people determine if they are suffering heart attacks or strokes and should seek medical attention, a clinical study suggests.

COLUMBUS, Ohio – If you’ve ever regretted ordering a spicy meal, take note: A new study identifying molecules that suppress the heat of chili peppers hints at the possibility of adapting these compounds into an “anti-spice” condiment for food that’s too fiery to eat. The research helps explain differences in chili pepper pungency, or spiciness, by identifying three compounds in a range of pepper samples that chemical analysis predicted, and study participants on a tasting panel confirmed, are linked to lower heat intensity. The findings have multiple potential applications: customized chili pepper breeding, ...

The universe is full of cosmic radiation that can be measured here on Earth. This cosmic radiation consists of –- produced by black holes, gigantic supernovae, or rotating neutron stars – a type of dead star. These particles contain energy. Sometimes, however, cosmic rays have a much higher energy than usual. We have known about this since 1962, but we still don’t know why. We also don’t know where this ultra-high-energy cosmic radiation comes from. Or do we? Supermassive ...

When deciding whom to trust, people are more likely to choose individuals who grew up with less money over those who went to private schools or vacationed in Europe, according to research published by the American Psychological Association. "Trust is essential for healthy relationships. Without it, romantic partnerships can fail, workplaces can suffer and social divisions can grow,” said lead researcher Kristin Laurin, PhD, a psychology professor at the University of British Columbia. “But what makes people trust someone in the first place?” To find out, researchers ran a series of experiments with more than 1,900 participants. They explored whether someone's ...
