Renewable Oocytes of Mice created hope in Human Fertility Treatment

...e theory, held for more than 50 years, that female mammals are born with a finite number of oocytes (eggs). Two years ago, international researchers speculated that mice could continue to produce eggs throughout puberty and adulthood. Although their speculation caused debate throughout the scientific commu...

...k to another also seem to be present in most other mammals and probably also in birds. ‘Set shifting occurs when you've learned to pay attention to one thing and then need to concentrate on something different,’ he said. ‘For instance, I could ask you to name the suit on playing cards as I turn them over,...

Studies Show That Brain Cells Do Not Regenerate But Remain The Same Throughout

...ents have indicated that brain cells can reform in mammals after all – including man. One problem with these findings has been the research methodology, as the most common way of measuring the age of nerve cells is extremely complicated, especially in man, and gives unreliable and controversial results. La...

A Human Brain Gene Could Hold Clues On The Evolution Of Brain Capacity

...is showed that HAR1 is essentially the same in all mammals except humans. There were only two differences between the chicken and chimp genomes in HAR1's sequence of 118 bases (bases are subunits of DNA, the As, Cs, Ts, and Gs that spell out the genetic code). This similarity means the DNA sequence remained ...

New Approach Assesses Risk of Water-Borne Pathogen Disease

...s have been found to be the primary gateway in all mammals for the detection of spoiled and unripe food sources. The receptor is found in a subpopulation of taste receptor cells of the tongue that do not function in sweet, bitter, or umami (the taste of monosodium glutamate) taste, the researchers report in...

An All Important Breakthrough Reached In Understanding T cell response For Parasitic Diseases

...asite that carries it, T. cruzi, is transmitted to mammals and humans through the bite of several genera of flying, biting insects. What intrigued Tarleton was that T cell response to infection from T. cruzi, while important to the body’s ability to fight disease, has remained somewhat cryptic because of the...

Most mammals also have this ability and in 2006, scientists working in the Oxford Auditory Neuroscience Group found that spatial hearing in ferrets has the ability to bounce-back or adapt to a hearing loss over time. Their brains are being "trained" to cope with ...

Regrowth of Zebrafish's Tail Fin may Offer Clues for Treating Human Injuries

...cause this gene might also inhibit regeneration in mammals and man. So, if we find ways of interfering with the function of Wnt5b, we might be able to promote regeneration.” Moon added that, because the same genes for turning on and turning off growth and development are found in humans, and drugs exist th...
