Two bacterial species collaborate to drive development of colon cancers

Patients with an inherited form of colon cancer harbor two bacterial species that collaborate to encourage development of the disease, and the same species have been found in people who develop a sporadic form of colon cancer, a study led by a Johns Hopkins Bloomberg~Kimmel Institute for Cancer Immunotherapy research team finds.

Neurons get stretches of orderly drumroll-like rumblings speckled with strong impulses

A neuron firing deep in the brain might sound a little like: Drumroll...cymbal crash! Drumroll...cymbal crash! Repeat. With emphasis on "repeat," according to a new study.

Elevated levels of chlorinated lipids linked to lung injury and death in sepsis patients

In a study published in the Journal of Clinical Investigation Insight, Saint Louis University scientists have found that elevated levels of chlorinated lipids are linked to sepsis, lung injury and death. The finding may offer a way to diagnosis and treat sepsis earlier, saving lives and avoiding serious side effects.

Neuroscientists identify 'anxiety cells' in the brain's hippocampus

Do your palms sweat when you walk down a poorly lit street at night? That feeling may be traced to the firing of newly identified "anxiety" cells deep inside your brain, according to new research from neuroscientists at Columbia University Irving Medical Center and the University of California, San Francisco.

Scientists discover role of two specific HOX genes in colon cancer development

In breakthrough colon cancer research, scientists at Christiana Care Health System's Center for Translational Cancer Research of the Helen F. Graham Cancer Center & Research Institute have discovered that over-expression of HOXA4 and HOXA9 genes in colon cancer stem cells promotes cell replication and contributes to the overpopulation of stem cells that drives colon cancer development.

Researchers turn to new biomarkers for predicting organ transplant rejection

Organ transplants save lives, but the story doesn't end when a patient emerges from the operating room. Rejection episodes, in which the immune system rallies against the new organ, can occur.
