Researchers develop criteria to detect bone mass deficiencies in children with chronic diseases

Pediatricians now have a practical tool to help determine whether children with chronic diseases like Crohn's, juvenile arthritis and anorexia nervosa are at increased risk for bone mass deficiencies, fracture or osteoporosis as they get older. Researchers developed standardized data on bone mass categorized by sex, age, and race.

A step nearer to understanding superconductivity

Critical high-temperature superconducting materials exhibit metallic behavior, similar to ordinary metals. This discovery paves the way for a deeper understanding and potentially higher critical temperatures, bringing us closer to room temperature superconductivity.

Researchers catch motion of a single electron on video

Researchers at Brown University have successfully captured the motion of a single electron in liquid helium using sound waves. The images show electrons moving through the fluid in snakelike paths, which are believed to be following vortex lines - a phenomenon akin to a tornado in superfluids.

2007 Image of the Year: Molecular imaging relates human brain chemistry to aggressive behavior

Scientists have discovered a statistical relationship between brain levels of the enzyme monoamine oxidase A (MAO) A and aggressive personality in healthy non-violent volunteers. The study found that higher MAO A activity was associated with less aggressive behavior, while lower MAO A activity was linked to more aggressive tendencies.

Sowing seed on salty ground

Researchers identified a sodium transporter gene that helps plants grow better in low-nutrient conditions. The OsHKT2;1 transporter allows plants to take up sodium, reducing the toxic effects of salt stress and even enhancing growth under nutrient-poor soils.

The bee that would be queen

A team of researchers from Arizona State University has discovered evidence that honeybees use a phylogenetically old molecular cascade to develop queens and workers. The findings, published in PLoS ONE, show that the TOR pathway is directly linked to nutrient-induced development, enabling two distinct phenotypes to evolve.

Breakthrough for treatment of fatal heart condition

Researchers at the University of Leeds have discovered a mechanism to prevent cardiac hypertrophy by increasing the levels of REST protein, halting the progression of the fatal heart condition. This finding offers a new approach to treating the cause of heart hypertrophy rather than its symptoms.

CIRM awards $3.79 million to Burnham Institute

The California Institute for Regenerative Medicine awarded $3.79 million to the Burnham Institute for the development of a shared laboratory and expansion of its training courses in human embryonic stem cell research. This funding will support the Institute's partner institutes and researchers, including those at the San Diego Consorti...

Other highlights from the June 6 JNCI

A prospective study found that aspirin use was associated with lower risk of cancer incidence and mortality, particularly among former and non-smokers. In contrast, integrin α7 gene mutations were identified in various cancers, including prostate and liver cancer, suggesting a potential role in cancer development.

Origins of nervous system found in genes of sea sponge

Researchers discovered genes in a sea sponge that resemble those found in human synapses, suggesting the nervous system evolved earlier than previously thought. The study reveals that sponges have genetic components of synapses, indicating they may have interacted with each other similarly to humans and mice.

Bigger horns equal better genes

Researchers found a correlation between horn growth and genetic diversity in alpine ibex, with greater diversity associated with longer horn lengths. The study suggests that genetic quality becomes more apparent as the animal ages, supporting the mutation accumulation theory of ageing.

Borderline personality disorder shows improvements with intensive psychotherapy

A new study reveals that intensive forms of talk therapy, particularly transference-focused psychotherapy (TFP), can reduce symptoms and improve social functioning in individuals with borderline personality disorder (BPD). TFP was found to show improvement in ten out of twelve domains studied, including reduced suicidal behaviors and i...

Evolutionary relevance of retinoic acid-induced craniofacial malformations

Researchers study retinoic acid-induced craniofacial malformations in mouse embryos to uncover the underlying mechanisms. They observe that these defects can transform into jaw apparatus structures resembling those found in other species, suggesting a common regulatory signaling mechanism governing jaw development across evolution.

New algorithms classify outcomes of nonsmall cell lung cancer patients

Two research teams developed models to predict NSCLC patient outcomes based on protein patterns. The new models, validated in independent groups, could help physicians decide treatment options for patients with NSCLC. Researchers identified a 25-signature proteomic signature associated with increased survival among NSCLC patients.
