PAST RELIGIOUS DIVERSITY AND INTOLERANCE HAVE PROFOUND IMPACT ON GENETICS OF IBERIAN PEOPLE

New research suggests that relatively recent events had a substantial impact on patterns of genetic diversity in the southwest region of Europe. The study, published by Cell Press on December 4th in the American Journal of Human Genetics, shows that geographical patterns of ancestry appear to have been influenced by religious conversions of both Jews [...]

Astronomy and space facilities overview

Australia Telescope National Facility
CSIRO’s Australia Telescope National Facility (ATNF) supports radio astronomy by operating radio telescopes at three observatories, near the New South Wales towns of
Parkes
Coonabarabran
Narrabri.
The Australia Telescope Compact Array (Narrabri) is the only major telescope of its kind in the Southern Hemisphere.
The Parkes telescope is used mainly for astronomy but is also occasionally contracted [...]

Searching for gravity waves

Pulsars are rapidly rotating neutron stars. By timing the arrival time of signals from pulsars, astronomers using the Parkes radio telescope hope to make the first direct detection of gravitational waves.
The Parkes Pulsar Timing Array team includes astronomers from Australia and USA. The project will observe about twenty pulsars regularly for five years.
What are gravity [...]

Primeras imágenes tridimensionales de la doble membrana de la bacteria de la tuberculosis

 
(NC&T) En la actualidad, unos diez millones de personas padecen la enfermedad anualmente, y todos los días mueren casi 4.000 pacientes por ella. El tratamiento médico es largo y no existen vacunas eficientes.
 
Esa es la razón del gran interés que grupos de investigación de diversas partes del mundo tienen en estudiar a los bacilos acidorresistentes, [...]

Nueva Técnica Que Muestra Más Detalles Sobre la Estructura de la Cromatina

 
Unos investigadores de la Universidad de Illinois han desarrollado una técnica para visualizar las células bajo el microscopio electrónico que permite imágenes más nítidas de la estructura de la cromatina, el apretado paquete de material genético y proteínas subyacente en los cromosomas.
Los científicos, desde hace más de un siglo, saben que las proteínas como las [...]
