Genetic mutation linked to walking on all 4s
|
What are the genes implicated in upright walking of humans? The discovery of four families in which some members only walk on all fours (quadrupedality) may help us understand how humans, unlike other primates, are able to walk for long periods on only two legs, a scientist will tell the annual conference of the European Society of Human Genetics today.

When is a worm not a worm?
|
One of the world’s strangest creatures has found its long-lost kin. Oxford University scientists have discovered that an extremely rare gutless worm is related to sea anemones and jellyfish, rather than similar-looking animals, reports this week’s Science. The finding could cause an evolutionary rethink.

'Fidgeting' gene found for weight loss
|
Mice that lack the gene for an important brain-signalling chemical are 10 times less physically active and carry twice as much body fat as their control counterparts, a study reveals. |

Infants Have 'Amazing Capabilities' That Adults Lack
|
Babies might seem a bit dim in their first six months of life, but researchers are getting smarter about what babies know, and the results are surprising.

Music has the power to alter mood – whether it’s energetic and uplifting to help you get through your workout or contemplative and relaxing to chill at the end of the day, music can inspire both movement and increased well being through rhythm and melody.x |

Nanomedicine opens the way for nerve cell regeneration
|
The ability to regenerate nerve cells in the body could reduce the effects of trauma and disease in a dramatic way. In two presentations at the NSTI Nanotech 2007 Conference, researchers describe the use of nanotechnology to enhance the regeneration of nerve cells. In the first method, developed at the University of Miami, researchers show how magnetic nanoparticles (MNPs) may be used to create mechanical tension that stimulates the growth and elongation of axons of the central nervous system neurons. The second method from the University of California, Berkeley uses aligned nanofibers containing one or more growth factors to provide a bioactive matrix where nerve cells can regrow.

Magnetic tweezers unravel cellular mechanics
|
Scheme of the micromechanical experiments. Magnetic poles (6 µm wide, 20 µm separation) generate a force on a paramagnetic bead positioned in the nucleus of a HeLa cell. Electric coils allow the control of amplitude and direction of the force. Magnetic yoke and electric coils are not to scale. |
