Chromosome rearrangements not as random as believed

..., because those men and their offspring are highly unlikely to be affected. Approximately one sperm in 100,000 has the rearrangement, so the chance of an affected sperm fertilizing an egg is exceedingly low. However, when that does occur, the child has a constitutional t(11;22) translocation--all of their cel...

Early human ancestors walked on the wild side

...anization of one's anatomy," Schwartz said. "It is unlikely that it could have evolved independently in multiple hominin lineages." Still, even if it only evolved once, the new research suggests there was a lot of tinkering within subsequent lineages. "Think of the robust australopithecines as having develope...

Aggressive subtype of breast cancer displays 'misbehavior' of X chromosomes

New brain hormone puts brakes on reproduction

...d come to believe that such a direct inhibitor was unlikely in the complex cast of hormones and factors in the reproductive system. The inhibiting or braking hormone may complement the "gas pedal" role played by another recently discovered hormone, kisspeptin, that stimulates GnRH. The discovery in rats, mice...

In states with intense WNV transmission, screening is likely to prevent cases of serious illness, but at a substantial cost. Where WNV is common, screening blood only from Ma...

Chemistry is unlikely to abandon the single-investigator model, but multidisciplinarity and the expense of research will drive many individual investigators toward collaborative work at centers where they can obtain access to expensive yet essential infrastructure. ...

Study links Alzheimer's disease to abnormal cell division

...ths before the formation of amyloid plaques, it is unlikely that the plaques themselves trigger the disease process. However, tiny clumps made up of several amyloid beta molecules (called micro-molecular aggregates) form before the plaques and may trigger the disease. Since the three mouse models tested in ...

How marine reserves are giving coral reefs a helping hand
