Development of more muscular trout could boost commercial aquaculture
|
|
A 10-year effort by a scientist to develop transgenic rainbow trout with enhanced muscle growth has yielded fish with what have been described as six-pack abs and muscular shoulders that could provide a boost to the commercial aquaculture industry.

Mystery of symmetry in vertebrates revealed
|
|
Some of our organs, such as the liver and the heart, are lateralized. As our bodies develop they mostly display bilateral symmetry across the vertebral column. A new molecular pathway, which plays a role in this symmetry in vertebrates, has recently been discovered.

Plotting and treachery in ant royal families
|
|
Social insects -- ants in particular -- are usually thought of as selfless entities willing to sacrifice everything for their comrades. However, new research suggests that ant queens are also prepared to compromise the welfare of the entire colony in order to retain the throne.

Diabetes' link to eating disorders explored
|
|
(Medical College of Georgia) Diabetics, under the gun to better manage their disease by controlling their food intake and weight, may find themselves in the sticky wicket of needing treatment that makes them hungry, researchers said.

Weight-bearing exercise does not prevent increased bone turnover during weight loss
|
|
(University of Missouri-Columbia) During weight loss, bones are being remodeled -- breaking down old bone and forming new bone -- at an accelerated rate. As a result, bone density is reduced, causing increased fragility. In a new study, University of Missouri researchers found that weight-bearing exercise, in this case, fast walking or jogging, did not prevent the increased bone turnover caused by weight loss.

Way to go: MBL scientists identify driving forces in human cell division
|
|
If you can imagine identical twin sisters at rest, their breath drawing them subtly together and apart, who somehow latch onto ropes that pull them to opposite sides of the bed—you can imagine what happens to a chromosome in the dividing cell.

First whole genome sequencing of family of 4 reveals new genetic power
|
|
The Institute for Systems Biology (ISB) has analyzed the first whole genome sequences of a human family of four. The findings of a project funded through a partnership between ISB and the University of Luxembourg was published online today by Science on its Science Express website. It demonstrates the benefit of sequencing entire families, including lowering error rates, identifying rare genetic variants and identifying disease-linked genes.
