Thyroid conditions raise risk of pregnancy complications
Pregnant women who have thyroid disorders face greater risk of preterm birth and other complications that have short- and long-term consequences for the health of mother and child, according to a recent study.

Rare genetic mutations team up to cause schizophrenia
A genome-wide analysis suggests there is “no single genetic recipe” for schizophrenia. Using a novel method of analyzing genetic variations in families, researchers at Johns Hopkins have found that individually harmless genetic variations affecting related biochemical processes may team up to increase the risk for schizophrenia.

New insights into protein function within the cell
Cells have a sophisticated system to control and dispose of defective, superfluous proteins in order to prevent damage to the body—and now a newly discovered enzyme function has also been added as vital to this process.

Understanding Learning and Memory, Synapses Shrink
Students preparing for final exams might want to wait before pulling an all-night cram session. Carnegie Mellon neuroscientists have discovered a new intermediate phase in neuronal development— repeated exposure to a stimulus shrinks synapses.

Beat 'guilt' by suppressing incriminating memories
New research published by an international team of psychologists has shown that people can suppress incriminating memories and thereby avoid detection in brain activity guilt detection tests.

Scientists identify molecular trigger for Alzheimer’s disease
New research establishes nature of malfunction in protein molecules that can lead to onset of dementia.

Small molecule could have big impact on cancer
Science has designed and synthesized a novel small molecule that might become a large weapon in the fight against prostate cancer.

Engineered stem cell advance toward treatment for ALS
Transplantation of human stem cells in an experiment conducted at the University of Wisconsin-Madison improved survival and muscle function in rats used to model ALS, a nerve disease that destroys nerve control of muscles, causing death by respiratory failure.

Overcomming hurdles to successful bone marrow transplants
Blood diseases such as leukemia, multiple myeloma, and myelodysplasia can develop from abnormal bone marrow and a dysfunctional bone marrow microenvironment that surrounds those cells. Until now, researchers have been unable to replace cells that make up the bone marrow microenvironment.

Down syndrome neurons grown from stem cells
Down syndrome, the most common genetic form of intellectual disability, results from an extra copy of one chromosome. Although people with Down syndrome experience intellectual difficulties and other problems, scientists have had trouble identifying why that extra chromosome causes such widespread effects.

Stem cells use signal orientation to guide division
Cells in the body need to be acutely aware of their surroundings. A signal from one direction may cause a cell to react in a very different way than if it had come from another direction. Unfortunately for researchers, such vital directional cues are lost when cells are removed from their natural environment to grow in an artificial broth of nutrients and growth factors.

Going live – immune cell activation in multiple sclerosis
New indicator molecules help scientists visualise how activation of auto-aggressive T cells in the body occurs.

First drug targets for infantile myofibromatosis disorder
Genetic mutations may be targeted by currently available cancer therapies for the disorder characterized by multiple tumors involving the skin, bone, and soft tissue.

'Should I stay or should I go?'
Cold Spring Harbor Laboratory scientists link brain cell types to behavior. The activity of 2 specific neuron types correlate with foraging decisions in mice.

Diabetes' genetics vary based on ethnic background
Ethnic background plays a surprisingly large role in how diabetes develops on a cellular level, according to two new studies led by researchers at the Stanford University School of Medicine.
