A new study shows that if you’re a juvenile moose trying to make it in the real world, you can’t beat an overprotective mom.
A new "smart catheter" that senses the start of an infection, and automatically releases an anti-bacterial substance, is being developed to combat the problem of catheter-related blood and urinary tract infections.
Nanoparticles show promise in restoring blood flow to the brain when administered soon after a traumatic brain or other injury.
Cancer stem cells are defined by three abilities: differentiation, self-renewal and their ability to seed a tumor. These stem cells resist chemotherapy and many researchers posit their role in relapse. A new study shows that melanoma cells with these abilities are marked by the enzyme ALDH, and imagines new therapies to target high-ALDH cells, potentially weeding the body of these most dangerous cancer creators.
Scientists have discovered a phenomenon never seen before in plants while studying molecular changes inside tree cells as wood is formed.
Researchers have examined SEER data on 25,476 pancreatic cancer patients, correlating days spent on medical care with disease stage, type of treatment and survival time. The first of its kind, the study is intended to provide physicians and patients with vital information needed to maximize quality of life for people with pancreatic cancer.
Researchers have shown for the first time that a specific sugar, known as GlcNAc ("glick-nack"), plays a key role in helping cancer cells grow rapidly and survive under harsh conditions. The finding suggests new potential targets for therapeutic intervention.
Scientists have discovered one of the ways the influenza virus disarms our natural defense system. The virus decreases the production of key immune regulating proteins in human cells that help fight the invader. The virus does this by turning on the microRNAs -- little snippets of RNA -- that regulate these proteins. The researchers are among the first to show the influenza virus can change the expression of microRNA to control immune responses in human lung cells.
A new record of past temperature change in the tropical Atlantic Ocean's subsurface provides clues as to why the Earth's climate is so sensitive to ocean circulation patterns.
Researchers have created a new type of biosensor that can detect minute concentrations of glucose in saliva, tears and urine and might be manufactured at low cost because it does not require many processing steps to produce.
Researchers have published the first annotated atlas of the Epstein-Barr virus (EBV) genome, providing the best look yet at how EBV interacts with human genes and proteins. EBV, which is thought to be responsible for one percent of all human cancers -- including B cell lymphomas, gastric carcinomas, and nasopharyngeal carcinomas -- establishes a latent infection in nearly 100 percent of infected adult humans.
Abnormalities in mitochondrial length promote the development of neurodegenerative diseases such as Alzheimer's.
