Researchers used sensors attached to 85 seals to track their movements and collect data about the marine environment. The results show that elephant seals adopted different strategies to find food, visiting colder waters nearer the continental shelf.
A new report from the University of Alberta finds that diet foods for children can lead to overeating and obesity. Children who consume low-calorie versions of high-calorie foods may develop a distorted connection between taste and calorie content, leading them to overeat as they grow up.
A study funded by ESRC suggests that ethical consumption is a political phenomenon rather than a market response. People are aware of issues like Fairtrade and environmental sustainability but often lack effective pathways to act on their concerns.
Researchers identified distinct genetic factors for blood pressure regulation in males and females, shedding light on gender-based disparities in cardiovascular health. The study's findings suggest that genetic diagnostic and therapeutic indices for hypertension must consider gender differences.
Researchers developed a new blood test to detect liver cancer in an early stage, improving detection accuracy by 70%. The test uses the ratio of two sugar groups on blood proteins to identify liver cancer in patients with cirrhosis.
Heat wave duration significantly impacts hospital admissions for fluid and electrolyte balance disorders, acute renal failure, and breathing issues. While individual hot days may have minor effects, prolonged heat waves can lead to increased health risks, particularly among the elderly.
Research suggests that female gender is associated with slower progression rates in certain renal diseases, possibly due to the protective effects of estrogen on kidney health. Estrogen inhibits the activity of transforming growth factor beta (TGF-β), which promotes scarring in the kidneys.
A new target for controlling high-density lipoprotein (HDL) cholesterol has been discovered by researchers at the University of Pennsylvania School of Medicine. The enzyme PCSK5A was found to increase HDL-C levels in mice, promoting reverse cholesterol transport and reducing the risk of heart disease.
A diet rich in protein may help slow the deterioration of elderly people's muscles. Researchers found that both young and elderly volunteers experienced increased muscle protein synthesis after consuming a moderate amount of protein-rich food. This is crucial for maintaining health, independence, and preventing muscle loss.
A literature review found a strong relationship between stress and periodontal diseases, with 57% of studies showing a positive link. Patients can reduce their risk by minimizing stress through healthy habits such as exercise, balanced eating, and positive mental attitude.
Nile tilapia significantly reduced Anopheles gambiae and Anopheles funestus mosquito populations by over 94%. The sustainable method provides a win-win situation for Kenyans, offering food and income while controlling malaria.
A new study published in Journal of Biogeography reveals that ancestors of Proteaceae plants must have crossed the Atlantic and Indian Oceans to reach their current distribution ranges. This finding challenges the long-held assumption that Gondwanaland's biota simply moved with the continents as they broke up.
Researchers from Case Western Reserve University found that blocking receptors responding to bacterial infections can nearly halve preterm deaths in mice. A synthetic TLR4 antagonist appears safe for mice mothers and pups.
Two studies have found significant gender-based differences in newborns' hearts and livers that may explain why female infant deaths are higher after heart surgery and pediatric liver transplants are less successful. Newborn girls' hearts accumulate more acid during ischemia, which may lead to injury, while their livers produce more an...
A recent study using spontaneously hypertensive rats found that testosterone supplements promote renal injury and exacerbate hypertension in aging male rats. The research suggests that natural decrease in testosterone levels with age may affect the progression of cardiovascular/renal disease in men taking testosterone replacement therapy.
Researchers will use a novel technique to track the dispersal of coral reef larvae and assess the effectiveness of marine protected areas in protecting fish stocks. The new approach, known as TRAnsgenerational Isotope Labeling (TRAIL), involves introducing an artificial tag into mature female fish just before spawning.
A study by McMaster University found that drinking milk after weightlifting increased fat loss and improved muscle gain compared to other beverages. The researchers discovered the milk group lost nearly twice as much fat and gained more muscle mass than other groups.
A study found that obesity is associated with higher levels of parathyroid hormone in patients with moderate to severe chronic kidney disease. Weight loss may help lower PTH levels, while other treatments could lead to weight loss. The association was strongest in patients with signs of malnutrition and inflammation.
Researchers at Florida State University have developed a new approach to targeting cancer cells using light-activated molecules that can induce apoptosis in both strands of DNA. By exploiting the unique property of these molecules, they can selectively kill cancer cells while sparing healthy ones.
No-till agriculture is more sustainable than conventional plow-based methods, which increase soil erosion. By preserving crop stubble and using disking, no-till farming builds soil fertility and stores carbon, offering a win-win solution for climate change.
A six-year study found that higher unemployment rates were associated with more penetrating trauma admissions, while lower unemployment rates correlated with increased blunt trauma admissions. The authors suggest that socioeconomic status and demographics play a role in the types of trauma admissions.
A new study aims to identify markers for deadly blood clots in menopausal women by analyzing blood platelets. Researchers are testing their theory as part of the Kronos Early Estrogen Prevention Study, with hopes that it can lead to tools for doctors to provide hormonal therapy commensurate with a woman's risk.
A new study finds that moderate long-term exercise in male and female mice induces a sex-dependent cardiac adaptation, with females exhibiting greater physiological changes. This research may help improve treatment strategies for women and men with heart disease.
A study in aged female rats suggests estrogen depletion may trigger high blood pressure and obesity after menopause. The researchers found that estrogen-depleted rats experienced significant weight gain, increased blood glucose levels, and elevated blood pressure compared to intact rats.
A study by researchers at the University of Washington found that excessive exposure to baby DVDs and videos can slow down infants' vocabulary acquisition. Infants who watched these productions for an hour a day understood an average of six to eight fewer words than those who did not watch them.
A study by Danish researchers found that acute sleep deprivation leads to increased urinary output and more salt in urine, particularly in men. The findings also showed a reduced nighttime dip in blood pressure, lower levels of sodium-regulating hormones, and excessive excretion of osmoles.
Researchers found a massive, rapid release of carbon may have triggered the Permian-Triassic extinction. The Great Bank of Guizhou fossil beds in China provide valuable insights into this event.
Peter J. Adams, an associate professor at Carnegie Mellon University, has been awarded a $900,000 research grant from the EPA to develop integrated models simulating air pollution from local to global scales. The study aims to improve understanding of particulate matter and its health impacts.
Women with diabetes lose protective effect of estrogen on kidneys, which normally reduces risk of chronic kidney disease. Research suggests that hormone ratio rather than absolute levels determines impact on diabetic kidney disease.
A study of lowland rainforests in New Guinea found low beta diversity across the study area, indicating widespread distribution of insect species and limited specialization. The results have implications for biological conservation and may suggest that bigger is better when preserving these forests.
A recent Yale University study found that 16% of chronically ill elderly patients refuse recommended medical and surgical interventions. The most frequently refused treatments were cardiac catheterization and surgery, with a combined refusal rate over 10%. Patients who refused treatments often cited fear of side effects as the primary ...
Researchers identified a key protein that blocks structural support, allowing cancer cells to migrate and metastasize. The discovery may lead to the development of anti-cancer drugs targeting this mechanism.
Researchers found that antidepressant medicines normalized decreased brain blood flow in patients with depression, while electroconvulsive therapy was associated with additional decreases. Objective imaging evaluations may support subjective clinical decisions in treating depression.
Researchers have found that grape seed polyphenols reduce salt-sensitive hypertension in young rats, while soy polyphenols protect against hypertension in estrogen-depleted/ovariectomized rats. Kudzu root extract also blunts blood pressure rise and improves glucose tolerance in animal models of insulin resistance.
