There's an existential crisis that often happens at dinner tables across the country: why won't kids eat their vegetables? Research has found that one reason could be a sensitivity to bitterness, fairly common among children — about 70 percent have it. But a new study led by Jennifer Orlet Fisher, director of the Family Eating Laboratory at Temple's Center for Obesity Research and Education, has found that adding a small amount of dip to a serving of vegetables helped bitter...

Tiny regulatory elements in the genome regulate the probability that olfactory sensory neurons choose a particular odorant receptor gene for expression The olfactory sensory neurons in the nasal mucosa perceive the myriad smells in the air with the aid of odorant receptors. Each sensory neuron chooses one and only one receptor gene for expression. The probability that a particular receptor gene is chosen for expression determines how many olfactory sensory neurons in total produce this...

Skin And Eyes Use Similar Mechanism For Sun Protection

A group of scientists at Brown University in Rhode Island discovered that the skin and eyes use the same molecular mechanism to protect themselves from the UV light. The discovery was reported in the journal Current Biology. The scientists discovered that the cells that create melanin - melanocytes - contain rhodopsin, a photosensitive receptor used in the eye to detect light. They also discovered that the body produces melanin to protect the cells much quicker than previously suspected....

New York University biologists have identified a new mechanism for regulating color vision by studying a mutant fly named after Frank ('Ol Blue Eyes) Sinatra. Their findings, which appear in the journal Nature, focus on how the visual system functions in order to preserve the fidelity of color discrimination throughout the life of an organism. They also offer new insights into how genes controlling color detection are turned on and off. Many biologists study how different cells develop to...

UCLA life scientists have identified for the first time a particular gene's link to optimism, self-esteem and "mastery," the belief that one has control over one's own life – three critical psychological resources for coping well with stress and depression. "I have been looking for this gene for a few years, and it is not the gene I expected," said Shelley E. Taylor, a distinguished professor of psychology at UCLA and senior author of the new research. "I knew there had to be a gene...
