New mechanism of inheritance could advance study of evolution, disease treatment
For more than a century, scientists have understood the basics of inheritance: if good genes help parents survive and reproduce, the parents pass those genes along to their offspring. And yet, recent research ...
Obese father rats have unhealthy daughters
Gene silencing instructions acquired through 'molecular memory' tags on chromatin
Scientists at Indiana University have unlocked one of the mysteries of modern genetics: how acquired traits can be passed between generations in a process called epigenetic inheritance. The new work finds ...
Personality is the result of nurture, not nature, suggests new study on birds
Researchers at the University of Exeter and the University of Hamburg investigated how personality is transferred between generations. They found that foster parents have a greater influence on the personalities ...
Dog DNA tests alone not enough for healthy pedigree, experts say
Breeding dogs on the basis of a single genetic test carries risks and may not improve the health of pedigree lines, experts warn.
Flies give another twist in the evolving story of heredity
Thanks to the father of modern genetics, Gregor Mendel, and his experiments cross-breading peas, the textbooks tell us that we know how inheritance works: we get 50% of our genes from our mums and 50% of our genes ...
Freshman weight gain: Women with heavy roommates gain less
(PhysOrg.com) -- A new University of Michigan study finds that college women with roommates who weigh more than average gain less weight during their freshman year than women with slimmer roommates: half a pound versus 2.5 ...
At the crossroads of chromosomes: Study reveals structure of cell division's key molecule
(PhysOrg.com) -- On average, one hundred billion cells in the human body divide over the course of a day. Most of the time the body gets it right but sometimes, problems in cell replication ...
Researchers find new insights into inherited retinal disease
An international team of scientists, led by researchers at the University of California, San Diego School of Medicine have discovered new links between a common form of inherited blindness affecting children and a gene known ...
Researchers identify gene mutation that causes rare form of deafness
Researchers have identified a gene mutation that causes a rare form of hearing loss known as auditory neuropathy, according to U-M Medical School scientists.
Scientists devise efficient way of learning about complex corn traits
There's no "silver bullet" gene or gene region that controls so-called complex traits in maize, commonly known as corn.
Perfect pitch study offers window into influences of nature and nurture
Practice, practice, practice might get you to Carnegie Hall, but for aspiring musicians, there's new evidence that genes may influence one's ability to get there, as well.
CHOP-led study detects dozens of genes for adult height
As much as 90 percent of variation in adult height may be caused by genetic inheritance, but a multitude of genes are involved. Most of these have yet to be discovered.
Teaching complete evolutionary stories increases learning
Many students have difficulty understanding and explaining how evolution operates. In search of better ways to teach the subject, researchers at Michigan State University developed complete evolutionary case studies spanning ...
