A study found that about 3% of critically endangered smalltooth sawfish are products of virgin births, with no genetic diversity loss. Researchers hope this discovery may help save the species from extinction due to overfishing and habitat loss.
A randomized trial tested an intervention to improve hesitancy about early childhood vaccines, but found it had minimal effect on mothers and doctors. The intervention, called Ask, Acknowledge, and Advise, aimed to encourage respectful dialogue with parents while recommending vaccination.
The discovery of lymphatic vessels in the brain could have significant implications for understanding and treating neurological diseases such as autism, Alzheimer's, and multiple sclerosis. The findings, published in Nature, suggest that these vessels may play a major role in immune responses to neurodegenerative diseases.
Researchers at National Institute of Fusion Science have developed a dispersion interferometer to measure electron density in atmospheric pressure low-temperature plasma with high accuracy. This breakthrough enables precise control over plasma parameters, leading to optimal plasmas for medicine and biology applications.
Research suggests that breastfeeding for at least six months can significantly reduce the risk of childhood leukemia. The study analyzed data from 18 studies and found a 19% lower risk compared to no breastfeeding or shorter breastfeeding periods. Breast milk's immunological components may play a key role in this association.
A study found that 67% of male Aka foragers in the Congo Basin used cannabis, protecting against parasitic worm infections, which are a major health problem in developing world populations. The researchers also suggest that tobacco use may have similar protective effects.
Research suggests that implementing a full seven day service in the NHS would cost up to £831m, exceeding initial estimates. The study found that removing weekend risks would eliminate some deaths, but not all, and may move problems to other days of the week.
The Universities of Leicester and Nottingham are developing a mini hybrid gamma ray camera to improve the diagnosis of tumours and lymph nodes from patients' bedsides. This handheld 'hybrid' technology combines optical and gamma imaging, allowing for more accurate surgical cancer treatments and reducing mortality and morbidity.
A study analyzing data from over 8,000 married couples found that the physical health and cognitive functioning of a person's spouse can greatly affect their own quality of life. The research suggests that targeting both partners' health and cognition is crucial for improving overall well-being in older adults.
A new study by Michigan State University business scholars estimates the costs and benefits of the Unfair Internet Gambling Enforcement Act, concluding that regulated online gambling would benefit both the industry and consumers, reducing uncertainty and confusion among firms and individuals.
A study of 34,157 postmenopausal women found that vitamin D and calcium supplements had no significant impact on menopausal symptoms, including hot flashes and fatigue. The results suggest that these supplements may not be an effective treatment option for relieving menopausal symptoms.
A study published in the American Journal of Community Psychology found that individuals with social support were less likely to experience emotional or verbal abuse. However, those living in neighborhoods with social and economic issues were more prone to physical violence, highlighting the need for co-ordinated services.
A study found that many medical tests are performed before low-risk surgeries despite guidelines, leading to surgical delays and patient anxiety. The Choosing Wisely campaign aims to raise awareness of unnecessary tests among physicians and patients.
Research shows that public access defibrillation on people suffering cardiac arrest is associated with a large increase in chances of survival. However, despite the great potential, publicly accessible Automated External Defibrillators (AEDs) are not being used enough.
Researchers compiled summaries of 71 leading cardiovascular drugs and their interactions with genetic variations to improve prescribing decisions. The study found that seven frequently prescribed medications warrant pharmacogenomic guidelines, which can help prevent adverse drug reactions and treatment non-response.
University of North Carolina researchers provide evidence that amino acids evolved into proteins, and single cells formed plants and animals. The close linkage between the physical properties of amino acids, genetic code, and protein folding is crucial to life's origins.
