Rare gene mutation affects protein in brain development
Though worlds apart, four unrelated families have been united in a medical mystery over the source of a rare inherited disorder that results in their children being born with abnormal brain growth and severe functional impairments.

Pregnancy nausea medication and major malformations
An analysis including more than 40,000 women exposed to the nausea medication metoclopramide in pregnancy, found the drug was not associated with significantly increased risk of major birth problems overall.

Stomach cells naturally revert to stem cells
New research has shown that the stomach naturally produces more stem cells than previously realized, likely for repair of injuries from infections, digestive fluids and the foods we eat.

New 3D method used to grow miniature pancreas
An international team of researchers from the University of Copenhagen have successfully developed an innovative 3D method to grow miniature pancreas from progenitor cells.

Football to flies: Lessons about traumatic brain injury
Faced with news of suicides and brain damage in former professional football players, geneticists bemoaned the lack of model systems for studying the insidious and often delayed consequences linked to head injuries.

Recovery from childhood ADHD?
Some people grow out of their childhood attention-deficit/hyperactivity disorder (ADHD) and some don't. In fact, around 50% of individuals diagnosed as children continue to suffer from ADHD as adults.

James Rothman Nobel Prize in Physiology or Medicine
Rothman helped reveal the mechanism that allows information-containing cell compartments—called vesicles—to transmit information both in the interior of the cell and to the surrounding environment.

Identifying new proteins crucial for hearing
Montréal scientists identified a group of proteins crucial for shaping the cellular organ responsible for detecting sounds.

Making memories has to be a speedy business
The brain is plastic - adapting to the hundreds of experiences in our daily lives by reorganizing pathways and making new connections between nerve cells. This requires that memories of new information and experiences are formed fast. So fast that the body has a special mechanism, unique to nerve cells, to enable that memories are made rapidly.

Birth gets the brain ready for the world
Neurons must be arranged in precise, well-organized maps crucial to translating perception into understanding. Birth triggers a drop in seratonin levels that stimulates the formation of neural circuits in both visual and somatosensory systems.

RNA folding is like choreographed origami
Folding RNA means pairing-up tags on specific molecules to fold and build a working proteins—much like folding orgami shapes.

Randy Schekman 2013 Nobel Prize for protein transport
Randy W. Schekman has won the 2013 Nobel Prize in Physiology or Medicine for his role in revealing the machinery that regulates the transport of proteins in our cells. He shares the prize with James E. Rothman of Yale University and Thomas C. Südhof of Stanford University.

The science behind Thomas Südhof's Nobel prize
Thomas Sudhof won his Nobel prize for his work in nerve cell communication — the firing patterns of our synapses that underwrite our consciousness, emotions and behavior.

PVD gene is essential for normal nerve branching
Our ability to detect heat, touch, tickling and other sensations depends on our sensory nerves. Now, for the first time, researchers at Albert Einstein College of Medicine of Yeshiva University have identified a gene that orchestrates the crucially important branching of nerve fibers that occurs during development.

Using motion blur to sharpen DNA mapping
With high-tech optical tools and sophisticated mathematics, Rice University researchers have found a way to pinpoint the location of specific sequences along single strands of DNA, a technique that could someday help diagnose genetic diseases through location of exact gene sequences.
