Los investigadores han estado cartografiando el centro de nuestra galaxia usando telescopios de rayos gamma de muy alta energía - el más sensible de su tipo - por más de 10 años. Los resultados fueron publicados en la revista Nature el 16 de marzo de 2016.

La tierra está siendo constantemente bombardeada por partículas de alta energía procedentes del espacio. En conjunto, estas partículas - protones, electrones y núcleos atómicos - son conocidos como la radiación cósmica o rayos cósmicos.  

Investigadores de la Universidad de Texas Medical Branch en Galveston han encontrado que las mujeres que toman la píldora anticonceptiva, que disminuyen y estabilizan los niveles de estrógeno, eran menos propensos a sufrir lesiones graves de rodilla. Los hallazgos están disponibles actualmente en Medicina y Ciencia en Deportes y Ejercicio, el diario oficial de la American College of Sports Medicine.

WWF researchers are celebrating the first live sighting of a Sumatran rhino in Kalimantan, the Indonesia part of Borneo, since it was thought to be extinct there. This is also the first physical contact with the species in the area for over 40 years and is a major milestone for rhino conservation in Indonesia.
 
The female Sumatran rhino, which is estimated to be between four and five years old, was safely captured in a pit trap in Kutai Barat in East Kalimantan on 12 March.
 
 

Researchers from The University of Texas Medical Branch at Galveston have found that women who take the birth control pill, which lessen and stabilize estrogen levels, were less likely to suffer serious knee injuries. The findings are currently available in Medicine & Science in Sports & Exercise, the official journal of the American College of Sports Medicine.

Female athletes are 1.5 to 2 times more likely than their male counterparts to injure their anterior cruciate ligament, or ACL. The ACL is a ligament that connects the top and bottom portions of the knee. Damage to this ligament is a serious athletic injury that can be career altering. Return-to-play rates after ACL injury are as low as 49 percent among soccer players. Also, this injury may lead to lifelong issues with knee instability, altered walking gait and early onset arthritis.

AU astrophysicists research cosmic particle accelerators with unparalleled energy

Researchers have been mapping the centre of our galaxy in very-high-energy gamma rays using these telescopes - the most sensitive of their kind - for over 10 years. The results were published in the journal Nature on 16 March 2016.

The earth is constantly bombarded by high energy particles from space. Together these particles - protons, electrons and atomic nuclei - are known as cosmic radiation or cosmic rays. The question of which astrophysical sources produce this cosmic radiation has remained a mystery to researchers for over a century. The problem is that the particles are electrically charged and are therefore deflected in interstellar magnetic fields, making it impossible to identify the astrophysical sources that produce them based on their arrival direction. Fortunately, however, the particles interact with light and gas in the neighbourhood of their sources, producing very-high-energy gamma rays that travel to the earth in straight lines. 'These gamma rays allow us to visualise the sources of cosmic radiation in the sky,' says Christopher van Eldik, a professor at FAU's Erlangen Centre for Astroparticle Physics (ECAP) and deputy director of the H.E.S.S. collaboration.
