Imaging cereals for increased crop yields

Researchers use computerized 3-D models to estimate plant yield based on measurable attributes, enabling rapid and accurate prediction of large numbers of plants' potential yields. The project aims to improve Australian agriculture's efficiency and competitiveness by producing more food for a growing population.

Restoring memory, repairing damaged brains

Researchers develop a way to duplicate the neural mechanism of learning in rats, restoring memory function. The team's artificial hippocampal system can strengthen internal brain memory and enhance cognitive processes, paving the way for potential treatments for Alzheimer's disease and other neurological disorders.

University of Louisville surgeons perform first prosthetic bypass graft with patient's stem cells at point-of-care

Researchers have successfully performed a new surgical procedure that uses a patient's own stem cells to line man-made bypass grafts, aiming to improve the long-term results of peripheral artery disease treatment. The first three patients enrolled in the clinical trial are doing well and report relief from symptoms almost immediately.

Searching for the 'perfect glass'

Scientists at Carnegie's Geophysical Laboratory have discovered a metallic glass that demonstrates long-range order among its atoms, a key characteristic of the elusive 'perfect glass' state. By applying high pressure, they were able to create a single crystal and preserve its structural order.

The possibilities of social networking and health

New guidelines for social media use in healthcare emphasize education over prescriptive advice. Researchers explore the potential benefits of social networking in breaking down barriers to reform, as seen in a Taiwan case study where the Minister of Health engaged with stakeholders through Facebook.

A stem cell target for expanding waistlines?

Scientists have discovered a protein marker on the surface of adipose stromal cells (ASCs), which drive fat expansion in the body. The finding may lead to developing a method to inactivate these cells, potentially treating obesity and improving regenerative therapies.

Why disparities in dental care persist for African-Americans even when they have insurance coverage

A study by Columbia University's Mailman School of Public Health found that African Americans with dental insurance still experience barriers to quality care, including limited coverage and inadequate provider availability. This leads to postponed treatment, worsening symptoms, and increased public health expenses.

Scientists develop a fatty 'kryptonite' to defeat multidrug-resistant 'Super bugs'

A team of Canadian scientists discovered that specific mixtures of antimicrobial agents presented in lipid (fatty) mixtures can significantly boost the effectiveness of those agents to kill multidrug-resistant bacteria. This new therapy has the potential to combat bacterial multidrug resistance, a growing clinical problem.

'Ultrawideband' could be future of medical monitoring

Researchers at Oregon State University have confirmed that ultrawideband technology could enable the development of body-area networks for continuous health monitoring. The technology has the potential to reduce healthcare costs and improve medical care by providing non-invasive, low-cost solutions for real-time health diagnosis.

Where have all the flowers gone?

Scientists have found a mid-season decline in wildflowers at high-altitude meadows, affecting pollinator populations. This shift is attributed to climate change, which alters moisture availability and flowering timing, leading to ecosystem-wide impacts on animals that feed on pollen and nectar.

How we come to know our bodies as our own

A recent study has identified the brain regions responsible for our sense of body ownership, revealing a unified view of the body as a single entity. The findings suggest that multisensory neurons integrate visual, tactile, and proprioceptive information to facilitate full-body ownership.

Depressed, pregnant women receive inconsistent treatment, have longer hospital stays

A recent study by the Medical College of Georgia found that depressed pregnant women often receive inconsistent treatment, leading to longer hospital stays. The lack of uniformity in addressing perinatal depression is attributed to providers feeling burdened and isolated in making decisions about complex issues.

Postnatal depression linked to depression in offspring until age 16

A recent study by Lynne Murray and colleagues found that postnatal depression in mothers is associated with a substantially increased risk of depression in their children until age 16. The researchers also discovered that infant attachment issues and lower child ego resilience are linked to the development of depression.

Imagination can influence perception

A novel study capitalizes on binocular rivalry to test metacognition of visual imagery. Participants rated vividness and effort for imagined patterns, which emerged as dominant patterns during the display. This suggests that our evaluations of mental imagery are directly related to performance in perceptual tasks.

Risk factor identified for acute aortic dissections

A study found that people with duplications in chromosome 16's 16p13.1 region are at 12-fold increased risk of thoracic aortic aneurysms and dissections. Researchers from UTHealth and Baylor College of Medicine discovered this association, which may lead to aggressive forms of the disease and require closer monitoring.
