Researchers developed a curvilinear camera with adjustable zoom capability inspired by the human eye. The camera combines simplicity and versatility, enabling applications in night-vision surveillance, robotic vision, endoscopic imaging and consumer electronics.
A new study found that female birds' fertility declines less quickly if they choose mates who became first-time fathers at a young age. This suggests that the 'history' of a male's reproductive past plays a role in his ability to care for his partner and offspring.
New UK research found that boys and girls who engage in physical activity with their best friend tend to be more active. The study suggests that encouraging children to exercise with friends outside of school can increase their physical activity levels.
African American patients with hypertension who viewed stories about real patients experienced better blood pressure control compared to usual care. High-volume hospitals for congestive heart failure showed improved patient outcomes but higher costs, contradicting previous studies that only focused on cost-effectiveness.
A DNA sequence variant, impairing kidney function channels, is associated with an increased risk of heart failure. The variant may be treated with drugs used for high blood pressure.
Scientists identified a previously unknown mechanism for massive endocytosis (MEND) in cells, where up to 75% of the cell plasma membrane can be reversibly engulfed. MEND preferentially targets low-ordered, cholesterol-containing membrane domains.
A new connection can significantly enhance the size of a network, according to researchers from Max Planck Institute. By tracing link by link, scientists found that after a certain number of new links, a sudden growth spurt occurs, leading to a dramatic increase in network size.
Warfarin users are more likely to die from traumatic injuries compared to non-users, especially among younger patients with severe head injuries. The study found a 50% increase in mortality from severe head injuries in patients under 65 on warfarin.
A Canadian study found that high birth weight among First Nations babies is associated with a significantly higher risk of postneonatal death. The research, published in the Canadian Medical Association Journal, compared over 5,000 births to First Nations mothers to over 630,000 births to French-speaking women.
Binge drinking is associated with high rates of adverse health effects, including increased risk of injury, violence, and death. The editorial emphasizes the need for a collective approach to controlling alcohol use across various stakeholders.
A minimally invasive procedure has shown promise in reanimating lower facial movement after paralysis, with all patients achieving improved symmetry and voluntary motion of the oral commissure. Directed physical therapy is necessary to achieve the best outcome, as spontaneous controlled smile requires intensive neuromuscular retraining.
Researchers at the Trudeau Institute and St. Jude Children's Research Hospital are studying white blood cell migration in response to viral infections, which could lead to improved vaccine strategies. The study has major implications for developing vaccines that promote immunity to respiratory infections.
A national audit of heart failure treatment in England and Wales found that patients admitted to general wards were twice as likely to die as those in cardiology wards. Women and older adults fared worse in terms of appropriate investigations and treatment.
A new study reveals that people's spatial memory biases develop as they become more familiar with a particular area. As individuals better understand the relationship between buildings on a campus, they tend to exaggerate distances and create cognitive biases.
U-M researchers found that breast cancer stem cells are regulated by mesenchymal stem cells from the bone marrow, creating a 'niche' for the cancer cells to replicate. By blocking signals from this niche, researchers hope to target and kill breast cancer stem cells using existing medications.
Researchers tested how brain network integrity relates to future cognitive decline in people with mild memory problems. They found altered patterns of brain activity in the default mode network among those who later progress to Alzheimer's disease compared to those whose memory remains intact.
Research reveals that smoking is behind 40-60% of the gender gap in mortality across Europe. The study found that deaths related to smoking and respiratory diseases were significantly higher for men than women.
