A new study has revealed the hidden emotional challenges patients go through following tooth loss. Patients highlight feelings of self-consciousness, shame or fear as well as physical sensations such as pain and sensitivity and worries about how tooth loss might impact their life.

Researchers use lessons from nanomedicine and digital twin technologies to address food insecurity and climate change.

Advanced technologies enable the controlled release of medicine to specific cells in the body. Scientists argue these same technologies must be applied to agriculture if growers are to meet increasing global food demands.

Innate immune cells including macrophages and neutrophils have unique properties that allows them to quickly accumulate in large numbers at the site of infection or injury. A new study establishes that macrophage in the adult ischemic muscle induce a phenotype switch into mural cells to support restoration of functional blood flow and thereby promote healing. This finding pinpoints macrophages as a potential target for therapeutically enhancing vascular integrity and healing of ischemic injuries.

Researchers have developed a new method for predicting dementia with over 80% accuracy and up to nine years before a diagnosis. The new method provides a more accurate way to predict dementia than memory tests or measurements of brain shrinkage, two commonly used methods for diagnosing dementia.

Current crises are distracting from the climate crisis and weakening support for climate action, a Europe-wide survey reveals.

People with high blood pressure have a higher risk of cognitive impairment, including dementia, but a new study suggests that engaging in vigorous physical activity more than once a week can lower that risk.

New research has found that teachers may be attributing signs of age-related immaturity in children, to conditions such as Attention-Deficit/Hyperactivity Disorder (ADHD) or Autism Spectrum Disorder (ASD). The results of the study showed that the youngest students in a class, with birth dates just before the school entry cut-off date, were overrepresented among children receiving an ADHD diagnosis or medication for the condition. Experts looked at how being one of the youngest children in a class can influence the likelihood of being diagnosed with ADHD or ASD. ADHD is a condition where individuals have significant challenges with attention and can be overly active. ASD is a complex developmental condition that relates to how a person communicates and interacts.

The number of calls about intentional exposures, such as illegal drug overdoses, that resulted in death among adults increased a whopping 233.9% between the beginning of 2007 and the end of 2021. And that's just one of several troubling poisoning trends.

A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG). The novel magnetometer, based on continuous-wave optically detected magnetic resonance, marks a significant step towards realizing ambient condition MEG and other practical applications.

Engineers have created a patent-pending method that creates layered perovskite nanowires with exceptionally well-defined and flexible cavities that exhibit a wide range of unusual optical properties beyond conventional perovskites.

The swirl of milk and espresso -- a small storm in your mug -- doesn't impact the dynamics of the milk proteins, according to research. Researchers took a molecular view of how milk proteins and caffeine molecules interact in water and in a coffee drink. The results suggest that the structures of milk proteins remain intact, meaning they retain their original mouthfeel and taste in your morning brew.

Scientists have discovered a highly effective, nontoxic, and less expensive way to lure hungry termites to their doom.

Mars has a distinct structure in its mantle and crust with discernible reservoirs, and this is known thanks to meteorites that scientists have analyzed. These results are important for understanding not only how Mars formed and evolved, but also for providing precise data that can inform recent NASA missions like Insight and Perseverance and the Mars Sample Return.

Researchers have isolated human monoclonal antibodies against influenza B, a significant public health threat that disproportionately affects children, the elderly and other immunocompromised individuals.

A novel, human-inspired approach to training artificial intelligence (AI) systems to identify objects and navigate their surroundings could set the stage for the development of more advanced AI systems to explore extreme environments or distant worlds, according to new research.

A new study has compared the amount of music and speech that children hear in infancy. Results showed that infants hear more spoken language than music, with the gap widening as the babies get older.

Trout living in rivers polluted by metal from old mines across the British Isles are genetically 'isolated' from other trout, new research shows.

Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.

Combining a new imaging instrument with the powerful adaptive optics capabilities of the Large Binocular Telescope, astronomers have captured a volcanic event on Jupiter's moon Io at a resolution never before achieved with Earth-based observations.
