Under blue light, researcher uses a syringe to extract purified DNA, which glows orange, from a tube. Insights into Common Brain Cancer
A large-scale, comprehensive study of glioblastoma has uncovered new genetic mutations with potential implications for the disease’s diagnosis and treatment.

The brain cells that fire when a person watches a brief film clip are triggered again when the person later recalls that imagery, a new study shows. The research offers insights into how the brain summons up past experiences and may also shed light on short-term memory disorders.

Pink stained brain tissue riddled with white holes.Prions Cross Species Barrier in the Laboratory
Researchers have gotten infectious prions from one species to turn normal prion proteins from a different species into infectious ones in a test tube. The technique will prove a valuable tool for understanding how prions cross species barriers.

Preterm infants born to mothers receiving intravenous magnesium sulfate—a common treatment to delay labor—are less likely to develop cerebral palsy than those whose mothers don’t receive it, according to a new report.

Researchers have used gene transfer to produce functional hair cells in the inner ears of mice. The accomplishment is an important step in developing potential strategies to treat hearing impairment.

By tweaking just 3 genes in living mice, scientists have transformed common adult pancreas cells into a rarer type of cell that produces insulin, a step toward eventually developing a new treatment for diabetes.

Tiny parasites that cause the tropical disease leishmaniasis may take advantage of the body’s initial defenses by hiding and surviving inside the fast-acting immune cells sent to devour them.

Eliminating a protein called furin from immune cells in mice can lead to development of autoimmune disease, a new study reports. The finding sheds light on the molecular processes that trigger autoimmunity.

Researchers have come up with a new way to monitor cancer using a special microchip that isolates tumor cells from the patient’s blood. The breakthrough could help doctors adjust to changes in tumors and personalize their patients’ treatments.

Researchers have identified 2 drugs that, in mice, seem to confer many of the healthful benefits of long-term exercise. The finding could lead to new treatments for muscle disorders, frailty, obesity and other conditions when exercise isn’t practical.

Three new studies by international research teams provide the most complete picture to date of the genetic glitches that may contribute to schizophrenia.

A promising new drug therapy for people with diabetes who have abnormal swelling in the eye—a condition called diabetic macular edema—proved less effective than traditional laser treatments in a new study.
