Training staff in West Africa enter data in computer.

Computer Models Can Help Guide Ebola Response

Computer model projections provide insight into the dynamics of the Ebola outbreak. Such models can help guide more effective control efforts.

Chloroviruses (red) on an algal cell.

Algal Virus Infects, Affects Humans

While studying cognitive function in healthy adults, researchers discovered DNA from an algal virus in throat samples. The virus was associated with subtle cognitive changes.

Mouse heart tissue.

Immune Cells in Heart Help it Mend

The hearts of mice have resident macrophages, a type of immune cell, that play a key role in recovery from damage. The findings suggest novel treatment strategies for heart failure.

Woman and her son, who was diagnosed with a rare genetic disorder.

Clinical Exome Sequencing Detects Disease-Causing Glitches

In some patients with suspected genetic conditions, a fast, powerful technique called whole-exome sequencing provided a molecular diagnosis.

Structure of the HIV surface spike protein.

The Structure and Dynamics of HIV Surface Spikes

Scientists illuminated the movement and complete structure of the spikes that the HIV virus uses to bind cells. The findings will help guide efforts to develop vaccines and treatments.

 Beta-amyloid plaque in a 3-D gel culture.

Human Cells Model Alzheimerís Disease

Researchers designed a cell culture system that reproduce key features of Alzheimer’s disease. The system may aid in drug development and the study of other neurodegenerative disorders.

Targeting Health Risks in Early Stages of Schizophrenia

Certain heart-related risk factors are present early in people diagnosed with schizophrenia spectrum disorders. The findings highlight early treatment opportunities.

Transmission electron micrograph of H7N9 virus

Progress Toward an H7N9 Avian Flu Vaccine

An experimental vaccine against H7N9 avian influenza prompted substantial immune responses in 59% of volunteers. The approach could lead to improved flu vaccines.

Human stem cell-derived beta cells.

Developing Insulin-Producing Cells to Treat Diabetes

Researchers transformed human stem cells into pancreatic beta cells that produce insulin and respond to glucose. The finding could lead to new therapies to treat diabetes.

More Knowledge Reduces Prenatal Testing

Pregnant women given computer-based information about prenatal screening were more likely to skip testing, especially invasive tests—even when the tests were free.

Prevotella

Diet Affects Autoinflammatory Disease Via Gut Microbes

A study in mice revealed how diet-induced changes to intestinal bacteria can influence autoinflammatory disease. The results could guide new approaches to these diseases.

Mutant AGT and peroxisomes together in a cell treated with DECA.

Compound Fixes Problem Seen in Rare Kidney Disease

In a proof-of-principle study, scientists identified a compound that can correct a cellular defect that causes a rare kidney disease.

How Genes Affect Facial Development

A zebrafish study shed light on how the structure of the face forms. Problems with equivalent genes in people can cause facial defects and other developmental issues.

The fibrin mesh of a blood clot.

Microgel Particles Boost Blood Clotting

Researchers developed microgel particles that mimic platelets and help form blood clots. The approach could lead to new treatments for uncontrolled bleeding.

Bacteriophage

Method Can Target Specific Microbes

Scientists designed a way to target and destroy specific DNA sequences in microbes. The approach might one day be used against pathogenic bacteria resistant to multiple antibiotics.

Fruit Flies Yield Insights Into Aging

Activating certain molecules in key tissues slowed aging in fruit flies. The findings could lead to a better understanding of aging processes in people.

A womanís shoulder muscles.

Controlling Muscle Repair

By manipulating a protein called Stat3, researchers regenerated muscle in mice. The approach may point the way to treatments for muscle-wasting diseases.

Cells moving in different ways.

New Mechanism of Cell Movement Revealed

Researchers described how a cellís nucleus can act as a piston to propel it through a 3-D matrix. The findings may help in the design of strategies to regenerate tissue and inhibit metastatic cells.
