Scientists reveal how RNA could have replicated on early earth

Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth – a key process in the origin of life.

Global warming contributes to higher cancer mortality in women

Scientists have found that global warming in the Middle East and North Africa is making breast, ovarian, uterine, and cervical cancer more common and more deadly.

Mild winter temperatures offer surprising mental health benefits

Higher ambient temperatures during the cold season were linked to reduced stress, improved life satisfaction, better self-reported health, and less loneliness in a large Swiss population study. While effects were modest at the individual level, they highlight the broader mental health impacts of seasonal temperature changes.

Endurance training leads to significant drops in vascular resistance and diastolic blood pressure

Eight months of supervised marathon training in Finnish adults led to moderate reductions in peripheral diastolic blood pressure, systemic vascular resistance, and extracellular water volume. Central (aortic) blood pressure showed a non-significant decline, highlighting the specific impact of exercise on vascular health.

Scientists discover natural compounds that tame chili pepper heat

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.

NIH researchers develop poly-metabolite score to measure ultra-processed food intake

For the first time, researchers at the National Institutes of Health (NIH) identified patterns of metabolites in blood and urine that can be used as an objective measure of an individual's consumption of energy from ultra-processed foods.

Air pollution fuels artery damage and accelerates heart disease, review finds

Researchers reviewed how air pollution, especially fine particulate matter (PM2.5), drives the development and worsening of atherosclerosis, a leading cause of heart attacks and strokes. Their findings highlight robust links between air pollution exposure, early artery changes, and underlying biological mechanisms fueling cardiovascular risk.

New short film sheds light on the impact of climate change on brain health

A powerful new short film, from the FutureNeuro Research Ireland Centre and RCSI University of Medicine and Health Sciences sheds light on the urgent need to address the impact of climate change on brain health.

Electromagnetic waves disrupt SARS-CoV-2 spike protein and lower infectivity

Researchers demonstrated that specific electromagnetic wave frequencies can disrupt the SARS-CoV-2 Spike protein structure in virus-like particles, leading to reduced infectivity in cell models. This proof-of-concept study suggests new avenues for non-chemical viral inactivation methods.

Novel nanoparticle could make ultrasound-based cancer treatments more effective and safer

Researchers have created a new kind of nanoparticle that could make ultrasound-based cancer treatments more effective and safer, while also helping prevent tumors from coming back.

Animal research reveals metabolic differences between tirzepatide and semaglutide

New animal research being presented at this year's European Congress on Obesity (ECO) in Malaga, Spain (11-14 May), reveals distinct metabolic adjustments to tirzepatide and semaglutide treatment, with tirzepatide temporarily increasing energy expenditure and semaglutide initially reducing energy expenditure.

DNA strand separation requires more force in crowded cellular environments

By creating a more true-to-life representation of DNA's environment, researchers at Northwestern University have discovered that strand separation - the essential process a "resting" double helix undergoes before it can initiate replication or make repairs - may take more mechanical force than the field previously believed.

Heat triggers sperm activation for fertilization in mammals

In mammals - including us humans - sperm are surprisingly picky about temperature, thriving best in conditions a few degrees cooler than normal body temperature.

NAD+ restoration improves mitochondrial function in Werner syndrome cells

A new research paper was published in Aging (Aging-US) on April 2, 2025, as the cover of Volume 17, Issue 4, titled "Decreased mitochondrial NAD+ in WRN deficient cells links to dysfunctional proliferation."

Children born with congenital syphilis face higher risk of hospitalization

Children born with syphilis are six times more likely to be admitted to hospital in their first five years of life compared to children not exposed to syphilis from their mother before birth, according to new research.

Extreme temperatures drive people toward high-fat diets, study finds

Short-term exposure to extreme temperatures alters dietary patterns by increasing fat intake, even when total calorie consumption remains stable. This shift, driven by physiological appetite regulation, raises the risk of high-fat diets and diet-related diseases, especially among vulnerable groups.

Study links ultraprocessed foods to higher risk of premature deaths, modeling shows

A study analyzing data from nationally representative dietary surveys and mortality data from eight countries (Australia, Brazil, Canada, Chile, Colombia, Mexico, United Kingdom, and United States) shows that premature deaths attributable to consumption of ultraprocessed foods (UPFs) increase significantly according to their share in individuals' total energy intake.

Urgent action needed to protect children from extreme heat in schools and child care settings

As Canadians face increasingly intense and frequent heat waves, health, education and legal experts are sounding the alarm on a growing crisis: extreme heat in schools and child care settings due to the escalating effects of climate change.
