Drug Improves Birth Rates for Women with Ovary Disorder

The drug letrozole is more effective than standard therapy in increasing live births for women with polycystic ovary syndrome—a leading cause of female infertility.

DNA molecule unwinding from a chromosome inside the nucleus of a cell.

Gene Changes Identified in Most Common Lung Cancer

Researchers identified DNA alterations that are involved in the development of lung adenocarcinoma. The findings may lead to more targeted therapies to treat this deadly cancer.

Supercooled rat liver.

Preserving Livers for Transplantation

A new technique increased the time that rat livers can remain viable outside the body. If the approach succeeds in humans, it could aid organ transplant efforts.

Low Levels of Lead Linked to Problems in Children

Low blood levels of lead were associated with increased behavioral and emotional problems in young children.

Cilia in liver cells.

Protein Critical to Cilia Development

Researchers gained insights into a key protein involved in ciliopathies, a class of genetic disorders that arise from defects in hair-like extensions called cilia that are found on cells throughout the body.

Storing Memories of Recent Events

Research into the mechanisms that underlie our ability to remember events could yield insights into the memory problems that come with normal aging and dementia.

Molecular Insights into a Target for Multidrug Resistance

The structure of a protein that bacteria need to spread the genes for antibiotic resistance could spur the development of novel drugs to combat multidrug-resistant bacteria.

Infant Exposure to Allergens May Help Prevent Wheezing

Exposure to certain allergens and bacteria within the first year of life may protect children from wheezing and allergies. The study’s findings suggest asthma prevention strategies.

Induced pluripotent stem cells form a structure with layers of cells.

Stem Cells Form Light-Sensitive 3-D Retinal Tissue

Researchers induced human stem cells to create a 3-D retina structure that responds to light. The finding may aid the study of eye diseases and could eventually lead to new therapies.

Revealing The Human Proteome

Researchers completed a draft map of the human proteome—the set of all proteins in the human body. The map will help advance studies of human health and disease.

Tooth sections stained with Toluidine blue.

Laser Therapy Prompts Regeneration in Teeth

A small dose of laser light activated stem cells in rat molars to generate dentin, a major component of teeth. The finding may lead to new approaches to tooth repair.

NMDA receptor

Structure of Receptor Involved in Brain Disorders

Scientists determined the structure of the NMDA receptor, an ion channel involved in many brain-related illnesses. The finding may aid in the development of future therapies.

Physical Activity Program Helps Maintain Mobility

Structured physical activity helped vulnerable older people maintain their mobility. The new study shows that moderate exercise might benefit even frail seniors.

Hair cells on the basilar membrane.

Hearing Different Frequencies

Researchers gained insights into how cells in the auditory system become organized to hear different frequencies. The findings could lead to new approaches for treating hearing loss.
