COLUMBUS, Ohio - A comprehensive analysis of 437 studies from around the world provides the best evidence to date that narcissism is an important risk factor for both aggression and violence, researchers said.
The link between narcissism and aggression was found for all dimensions of narcissism and for a variety of types of aggression. Results were similar regardless of gender, age, whether they were college students, or country of residence.
A study by Monash University and Alfred Health found a 70 per cent reduction in one type of human papillomavirus (HPV) in gay and bisexual men after the implementation of the school-based HPV vaccination program.
The HYPER2 study, published in The Lancet Infectious Diseases, and led by Associate Professor Eric Chow, found there was a significant reduction in all four vaccine-preventable genotypes in gay/bisexual men aged 16-20 years following the introduction of the vaccine for boys in 2013.
In the last year, one thing has become clear: we cannot live life without risk. In fact, every part of our daily routines became subject to analysis: How risky is the action and is its value worth the potential cost?
Risk analysis, though seemingly more ever-present in our thoughts today, has always been a part of how we operate and how the systems around us work. As new pressures, such as climate change, deepen, the accuracy and reliability of risk analysis models regarding issues as basic as the cleanliness of our drinking water have become more important than ever.
A study published today in Scientific Reports suggests that new health challenges may be emerging as a result of conservationists' success in pulling mountain gorillas back from the brink of extinction.
An investigation carried out by the astrophysicists of the Instituto de Astrofísica de Canarias (IAC) ?ofia Chrobáková, a doctoral student at the IAC and the University of La Laguna (ULL), and Martín López Corredoira, questions one of the most interesting findings about the dynamics of the Milky Way in recent years: the precession, or the wobble in the axis of rotation of the disc warp is incorrect. The results have just been published in The Astrophysical Journal.
The bacterium Staphylococcus epidermidisis primarily a harmless microbe found on the skin and in the noses of humans. Yet some strains of this species can cause infections - in catheters, artificial joints, heart valves, and in the bloodstream - which are difficult to treat. These bacteria are often resistant to a particularly effective antibiotic, methicillin, and are among the most feared germs in hospitals. How these usually harmless skin microbes become deadly pathogens has been unclear up to now.
On 17 May 2021, the UK moved to step three of the Government's Roadmap out of Lockdown - which allowed for the lifting of a ban on foreign travel. Yet, travelling to amber and red list countries still carries strict regulations. UK residents can use proof of vaccination or Covid status (via the NHS app) to comply with travel restrictions in different countries - a scheme known as vaccine passports. However, issues remain to be resolved on how they will be implemented and used, and public opinion appear polarised.
DURHAM, N.C. -- Biomedical engineers at Duke University have developed an automatic process that uses streamlined artificial intelligence (AI) to identify active neurons in videos faster and more accurately than current techniques.
The technology should allow researchers to watch an animal's brain activity in real time, as they are behaving.
The work appears May 20 in Nature Machine Intelligence.
Schizophrenia is a heterogeneous psychiatric disorder characterized by positive symptoms such as hallucinations and delusions, negative symptoms such as apathy and lack of emotion, and cognitive impairment. We have reported that VB6 (pyridoxal) levels in peripheral blood of a subpopulation of patients with schizophrenia is significantly lower than that of healthy controls. More than 35% of patients with schizophrenia have low levels of VB6 (clinically defined as male:
Tsukuba, Japan - Carbonic anhydrases are essential enzymes that are present in virtually all living things; all eight classes of carbonic anhydrases that have been identified to date need a metal ion to function. But now, researchers from Japan have discovered that metal is not crucial for all carbonic anhydrases.
Tokyo, Japan - Most people don't think much about the food scraps they throw away; however, investigators from the Institute of Industrial Science at The University of Tokyo have developed a new method to reduce food waste by recycling discarded fruit and vegetable scraps into robust construction materials.
Researchers have flipped traditional 3D printing to create some of the most intricate biomedical structures yet, advancing the development of new technologies for regrowing bones and tissue.
The emerging field of tissue engineering aims to harness the human body's natural ability to heal itself, to rebuild bone and muscle lost to tumours or injuries.
A key focus for biomedical engineers has been the design and development of 3D printed scaffolds that can be implanted in the body to support cell regrowth.
Digital medicine is opening up entirely new possibilities. For example, it can detect tumors at an early stage. But the effectiveness of new AI algorithms depends on the quantity and quality of the data used to train them.
A rare mutation that causes Parkinson's disease-like symptoms interrupts the flow of dopamine in the brain, suggests a study in fruit flies published today in eLife.
The findings provide more detailed insights about why young children with this mutation develop these symptoms. This new information, as well as previous evidence that therapies helping to improve dopamine balance in the brain can alleviate some symptoms in the flies, suggests that this could be a beneficial new treatment strategy.
BUFFALO, N.Y. - To improve the development of new saliva-based diagnostic tests and personalized medicine, the National Institute of Dental and Craniofacial Research (NIDCR) has supported the development of the Human Salivary Proteome Wiki, the first public platform that catalogs and curates data on each of the thousands of proteins within our saliva.
