Benzodiazepine Often Used in Older People Despite Risks

An analysis of prescription patterns suggests the need for strategies to reduce the use of benzodiazepines—a class of sedative and anti-anxiety medications—in older adults.

Immune System Reset May Halt Multiple Sclerosis Progression

Three-year results from a clinical trial suggest that depleting and then re-establishing the immune system can alleviate a type of early-stage multiple sclerosis.

Hydrogen sulfide molecules.

Pathways Underlying the Benefits of Calorie Restriction

A mouse study revealed that some of the health benefits of calorie restriction are due to increased production of the gas hydrogen sulfide. The finding could have potential clinical applications.

Unsafe Infant Bedding Use Still Common

Despite recommendations against the practice, many infants are still placed to sleep with bedding that increases the risk of suffocation and sudden infant death syndrome.


Drug Improves Function in Rats with Spinal Cord Injuries

Researchers developed a drug that allows spinal cord neurons to grow after injury, improving movement and bladder function. The approach may lead to treatments for paralysis and other conditions.

Comparing the Mouse and Human Genomes

Results from an international genomics effort will help scientists better understand how and when mouse models can best be used to study human biology and disease.

Gene Therapy Used to Treat Hemophilia

Experimental gene therapy improved symptoms for as long as 4 years in men with severe hemophilia. The study shows the potential for gene therapy to treat this and other disorders.

Damaged DNA

Structural Snapshots of Damaged DNA

Researchers revealed how nucleotides damaged by oxidative stress block DNA repair mechanisms. The cell death triggered by this process is thought to play a role in many diseases.

New Drug for Common Liver Disease Assessed

An experimental drug showed promising results and potential problems in treating a common liver disease. The drug’s long-term effects still need to be assessed.

Small mitochondria.

Targeting Parkinson’s Disease Pathways

By blocking mitochondria division, scientists were able to restore function in mouse models of Parkinson’s disease. These preliminary findings suggest a strategy to slow or halt the disease.

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.
