Stanford team develops single cell genomics technique to reverse engineer developing lung
In a feat of reverse tissue engineering, Stanford researchers took lung cells from the embryos of mice at different points in their development cycles; using single-cell genomic analysis, they recorded what genes were active in each cell at each time.

Fish from acidic ocean waters less able to smell predators
Fish living on coral reefs where carbon dioxide seeps from the ocean floor were less able to detect predator odor than fish from normal coral reefs, according to a new study.

How a Silly Putty ingredient could advance stem cell therapies
The sponginess of the environment where human embryonic stem cells are growing affects the type of specialized cells they eventually become, a University of Michigan study shows.

New mouse model could revolutionize research in Alzheimer's disease
In a study published today in Nature Neuroscience, a group of researchers led by Takaomi Saido of the RIKEN Brain Science Institute in Japan have reported the creation of two new mouse models of Alzheimer's disease that may potentially revolutionize research into this disease.

New technique takes cues from astronomy and ophthalmology to sharpen microscope images
Scientists are always in search of a sharper image. The complexity of biology can befuddle even the most sophisticated light microscopes.

New 'tunable' semiconductors will allow better detectors, solar cells
Researchers have discovered a way to use existing semiconductors to detect a far wider range of light than is now possible, well into the infrared range.

Regenerating muscle in Duchenne muscular dystrophy: Age matters
Researchers reveal novel cellular and molecular elements of muscle repair.

Finding the switch: Researchers create roadmap for gene expression
In a new study, researchers from North Carolina State University, UNC-Chapel Hill and other institutions have taken the first steps toward creating a roadmap that may help scientists narrow down the genetic cause of numerous diseases.

Reduction in HPV in young women in England seen, following national immunization program
A study conducted by Public Health England shows a reduction in two High Risk human papillomavirus types in sexually active young women in England, following the introduction of a national immunization program.

Glasses strong as steel: A fast way to find the best
Scientists at Yale have devised a dramatically faster way of identifying and characterizing complex alloys known as bulk metallic glasses, a versatile type of pliable glass that's stronger than steel.

Tiny particles could help verify goods
Chemical engineers at MIT hope smartphone-readable microparticles could crack down on counterfeiting.

Virus-fighting genes linked to mutations in cancer
All cancer-causing processes leave a distinct mutational imprint or signature on the genomes of patients.

Mechanism, and possible treatment, for immune suppression in liver disease uncovered
The mechanism which underlies the susceptibility of liver disease patients to life-threatening infection has been uncovered by Wellcome Trust-funded medical scientists, who have also suggested a possible treatment to reverse immune suppression in these patients.

Wolves at the door: Study finds recent wolf-dog hybridization in Caucasus region
Hybridization of wolves with shepherd dogs in the Caucasus region might be more common, and more recent, than previously thought, according to a recently published study in the Journal of Heredity.

Gene linked to pediatric kidney cancer suggests new strategies for kidney regeneration
Nearly one-third of cases of Wilms tumor, a pediatric cancer of the kidney, are linked to a gene called Lin28, according to research from Boston Children's Hospital.

Hereditary trauma
Extreme and traumatic events can change a person -- and often, years later, even affect their children.
