Scientists found that low concentrations of toxic chemicals can affect aquatic creature behavior, including feeding and swimming speed. The study calls for low dose and mixture toxicity testing to assess the impact of complex pollutant mixtures on aquatic ecosystems.
A new electronic frailty index (eFI) tool helps GPs identify older people at risk of frailty and poor health outcomes. The eFI uses routine data from GP databases and has been shown to flag up patients who are living with mild, moderate, or severe frailty.
Researchers have discovered evidence of dynamical dark energy, suggesting that the nature of dark energy may not be a constant vacuum energy. The discovery was made possible by high-precision measurements of Baryonic Acoustic Oscillations and will require confirmation from next-generation astronomical surveys.
Researchers have identified proteins that control cell complexity in animals, revealing a key difference between humans and simpler organisms like fruit flies and sea urchins. The study found that specific genes interact with chromatin to regulate cellular processes, contributing to the increased complexity of mammals.
The University of Portsmouth's AIR Network aims to address the significant contributor to respiratory and cardiovascular disease in low-resource settings. By engaging with local communities through arts, theatre, and other methods, researchers will explore co-creating viable interventions to reduce exposure to air pollution.
Scientists have developed a 3D all-human reproducible and reliable model of the blood brain barrier, which could pave the way for better, more efficient and reliable tests of drugs to treat brain diseases. The model was created using human cells to simulate the human blood-brain barrier.
Research by Jamie Whitehouse suggests that stress behaviours like scratching can be a sign of social stress, reducing the likelihood of conflict and promoting transparency. In rhesus macaques, stress scratching lowered aggression rates, especially among non-friends.
A new study by Dr Daniel Brown defines thriving as a combination of personal development, succeeding at mastering something, and feeling good about life. The research outlines six recommendations for future studies on thriving.
A new analysis argues that decades of research on apes' social intelligence is based on wishful thinking and flawed science. Scientists have assumed human babies are more socially capable than ape adults, leading to biased research designs.
Researchers found that nectar attracts herbivores like sawflies, which eat petals and nectaries, away from critical flower parts. This 'decoy' strategy allows flowers to protect their reproductive tissues, enhancing pollination success.
Research establishes first clear link between depression and hindsight bias, a distorted view of the past. People with depression show exaggerated perceptions of foreseeability and inevitability for negative event outcomes, reinforcing feelings of helplessness.
A new study reveals that thriving in elite sports requires a combination of internal and external factors, including optimism, focus, and high motivation. The research found that athletes who are highly motivated, develop holistically, and have a sense of belonging tend to thrive at the highest level.
A new study highlights the significance of educating men to encourage women to seek medical help earlier due to cultural and religious barriers. Community nurses are found to be the most effective channel in raising breast cancer awareness in India's urban areas.
The European Association for Neuro-Oncology has developed new guidelines to treat adult patients with astrocytic and oligodendroglial gliomas more effectively. The guidelines provide guidance on prevention, early diagnosis, and treatment options, aiming to limit unnecessary treatments and costs.
Researchers at the University of Portsmouth have identified two molecules, CD15s and CD62E, that play a key role in brain tumor cells binding to blood vessels. By blocking these molecules, it may be possible to prevent brain tumors from developing in patients with non-small cell lung cancer.
A new study found that citizen science volunteers are mainly motivated by a desire to learn and enhance their scientific knowledge. The research, led by the University of Portsmouth, surveyed 2000 online volunteers and discovered that this motivation was the number one driver for participation.
A new project, PONToon, aims to improve the employment rates of socially excluded women by boosting their digital skills and knowledge. The project will develop a free digital toolkit with engaging tools such as virtual reality interviews, webinars, and bespoke computer game experiences.
Researchers have produced new maps of dark matter dynamics in the Universe, revealing detailed information about matter streams and velocities. This study uses legacy survey data to build on previous research and provides insights into the nature of dark matter.
A new study using physics to predict where and how dialects occur suggests that dialects tend to move outwards from population centers. This theory explains why cities have their own dialects and how language boundaries get smoother over time.
Researchers are investigating the secrets of sharks' ability to shed slime and biofilms, which could lead to sustainable anti-fouling coatings for ships. The study aims to develop new technologies inspired by nature to mitigate hull fouling and its impact on the environment.
