A new study indicates an essential role for a maternally inherited gene in embryonic development. The study found that zebrafish that failed to inherit specific genetic instructions from mom developed fatal defects earlier in development, even if the fish could make their own version of the gene.
Nearly 6 million Americans have bipolar disorder, and most have probably wondered why. After more than a decade of studying over 1,100 of them in-depth, a team of scientists has an answer -- or rather, seven answers.
A new genetic analysis of fungal yeast infections (candidiasis) from around the world has revealed surprising secrets about how these microbes reproduce and cause disease, according to a new study published in Current Biology from researchers at the Centre for Genomic Regulation in Barcelona, Spain.
About one third of all medicine binds to the same type of receptor in the human body. An estimated 3 percent of the population have receptors of this type that are so genetically different that they are predisposed to altered, ineffective or adverse responses to medicine, a new study from the University of Copenhagen and the MRC Laboratory of Molecular Biology in Cambridge shows.
Human memory has evolved so people better recall events encountered while they are thinking about raising their offspring, according to a new study conducted by researchers at Binghamton University, State University of New York.
Salk scientists develop new approach to identify important undiscovered functions of proteins.
LSU describes a distinctive new species of antbird from humid montane forest of the Cordillera Azul, Martin Region, Peru.
At least a third of reactions in children with food-induced anaphylaxis to a known allergen occur under adult supervision, according to a new study led by AllerGen researchers in Quebec, Ontario and Alberta. The findings, published in the November issue of Pediatric Allergy and Immunology, reveal that inadvertent exposures to a known food allergen in children are frequent, and in the majority of supervised reactions, adults other than the child's parents were present.
Researchers at the University of Colorado Anschutz Medical Campus have discovered that color vision in mice is far more complex than originally thought, opening the door to experiments that could potentially lead to new treatments for humans.
Genetics may play a role in determining whether patients experience chronic pain after surgery, suggests a study published today in the Online First edition of Anesthesiology, the peer-reviewed medical journal of the American Society of Anesthesiologists (ASA). Aside from genetic factors, the study also found patients younger than 65 years old, males and those with a prior history of chronic pain were at increased risk.
