Groundbreaking research links autism to gut microbes
Feeding mice a beneficial type of bacteria can ameliorate autism-like symptoms.
Brain repair possible after injury or Alzheimer's disease
Researchers at Penn State University have developed an innovative technology to regenerate functional neurons after brain injury, and also in model systems used for research on Alzheimer's disease. The scientists have used supporting cells of the central nervous system, glial cells, to regenerate healthy, functional neurons, which are critical for transmitting signals in the brain.
Brain connections may explain why girls mature faster
Our brain re-organises connections throughout our life. The process begins earlier in girls — which may explain why girls mature faster than boys during the teenage years.

Naturally occurring radioactivity muddles DNA
Natural radioactivity within DNA can alter chemical compounds, providing a new pathway for genetic mutations.
Breaking cycle of wounds that refuse to heal
By controlling levels of reactive oxygen within chronic wounds of genetically modified mice, researchers were able to normalize conditions and heal the wounds.
Supercomputers identify switch controlling cell
If scientists can control cellular functions such as movement and development, they can cripple cells and pathogens that are causing disease in the body.

New technique for stem cell creation
A novel technique could resolve a snag in stem cell research for application in regenerative medicine—a new strategy for reprograming cells in vivo to act like stem cells that forgoes the risk of causing tumors.
How pet dogs protect against asthma and infection
Children's risk for developing allergies and asthma is reduced when they are exposed in early infancy to a dog in the household, and now researchers have discovered a reason why.
Aging cells unravel DNA, in seniors and Progeria kids
Senescent cells are metabolically active but incapable of dividing — and are a key mechanism for preventing the spread of cancer cells. Strikingly, cells from Progeria patients suggest their arrested cells follow the same senescence as normal aging.

Brain study: striking differences between men and women
Penn Medicine brain imaging study helps explain different cognitive strengths in men and women.
Brain waves in hippocampus may code neurons
Observing the theta-gamma oscillations — or “brain waves” — in the hippocampus of model animals, a brain region involved in learning and memory, scientists have previously determined these oscillations are associated with information processing during exploration and spatial navigation.
Brittle-bone babies helped by fetal stem cell grafts
Osteogeneis imperfecta (OI) is a congenital bone disease that causes stunted growth and repeated, painful fracturing. Ultrasound scans can reveal fractures already in the fetus, and now an international team of researchers from Sweden, Singapore and Taiwan have treated two babies in utero by injecting bone-forming stem cells.

Environmental change triggers adaptation
In at least one variety of cavefish, an agent of evolutionary adaptative change is the heat shock protein known as HSP90.
Programming smart molecules
Computer scientists have put powerful probabilistic reasoning algorithms into the hands of bioengineers.
Scientists discover double meaning in genetic code
Scientists have discovered a second code hiding within DNA. This second code contains information that changes how scientists read the instructions contained in DNA and interpret mutations to make sense of health and disease.
