Materials science: Muscle mimic
- Autor:
Elliot L. Chaikof
- Resumen:
An elastic polymer has been made whose molecular structure mimics that of titin, a protein found in muscle. The resulting material is tough, stretchy and dissipates energy — just like muscle itself

Gene regulation: Breaking the second genetic code
- Autor:
J. Ramón Tejedor
- Resumen:
Diverse messenger RNAs, and thus proteins, can be generated from a single piece of DNA. A computational approach is helping to uncover complex combinatorial rules by which specific gene instructions are selected

Olfactory pattern classification by discrete neuronal network states
- Autor:
Jörn Niessing
- Resumen:
The brain is apt to sort sensory stimuli into discrete perceptual categories, but the neuronal activity behind this capability has been unclear. Here, the problem has been investigated by presenting zebrafish with different concentrations or types of odours. The results show that the activity of neuronal populations in the olfactory bulb is largely insensitive to changes in odour concentration, but that morphing one odour into another produces abrupt transitions between odour representations

Deciphering the splicing code
- Autor:
Yoseph Barash
- Resumen:
The coding capacity of the genome is greatly expanded by the process of alternative splicing, which enables a single gene to produce more than one distinct protein. Can the expression of these different proteins be predicted from sequence data? Here, modelling based on information theory has been used to develop a 'splicing code', which can predict, with good accuracy, tissue-dependent changes in alternative splicing

H2 emission arises outside photodissociation regions in ultraluminous infrared galaxies
- Autor:
Nadia L. Zakamska
- Resumen:
Ultraluminous infrared galaxies are among the most luminous objects in the local Universe and are thought to be powered by intense star formation. In these objects, the rotational lines of molecular hydrogen (H2) observed at mid-infrared wavelengths are not affected by dust obscuration, but the source of excitation has been unknown. Here it is found that H2 emission originates outside the obscured regions; it is proposed that H2 emission traces shocks in the surrounding material that are excited by interactions with nearby galaxies
