UCLA researchers determine toxic levels of Alzheimer's clusters in brain

— 12 Aug 2009 10:56 | Health

Scientists have long suspected that Alzheimer's disease (AD) is caused by a small protein called the amyloid beta-protein (Abeta). This protein clumps or binds to itself, eventually... — full story

Turbulence responsible for black holes' balancing act

— 15 Jul 2009 00:47 | Astronomy

New simulations reveal that turbulence created by jets of material ejected from the disks of the Universe's largest black holes is responsible for halting star formation. Evan Scannapieco,... — full story

Spontaneous assembly

Over the past 19 years Hubble has taken dozens of exotic pictures of galaxies going 'bump in the night' as they collide with each other and have a variety of close encounters of the galactic kind. Just when you thought these interactions couldn't look any stranger, this image of a trio of galaxies, called Arp 194, looks like one of the galaxies has sprung a leak. The bright blue streamer is really a stretched spiral arm full of newborn blue stars. This typically happens when two galaxies interact and gravitationally tug at each other. Resembling a pair of owl eyes, the two nuclei of the colliding galaxies can be seen in the process of merging at the upper left. The blue bridge looks like it connects to a third galaxy. In reality the galaxy is in the background and not connected at all. Hubble's sharp view allows astronomers to try and visually sort out what are foreground and background objects when galaxies, superficially, appear to overlap. This picture was issued to celebrate the 19th anniversary of the launch of the Hubble Space Telescope aboard the space shuttle Discovery in 1990. During the past 19 years Hubble has made more than 880,000 observations and snapped over 570,000 images of 29,000 celestial objects, (c) NASA, ESA, and the Hubble Heritage Team (STScI/AURA)Hubble celebrates its 19th anniversary with a 'fountain of youth'

To commemorate the Hubble Space Telescope's 19 years of historic, trailblazing science, the orbiting telescope has photographed a peculiar system of galaxies known as Arp 194. This... — full story

This composite image shows the massive galaxy cluster MACSJ0717.5+3745 (MACSJ0717, for short), where four separate galaxy clusters have been involved in a collision, the first time such a phenomenon has been documented. Hot gas is shown in an image from NASA's Chandra X-ray Observatory and galaxies are shown in an optical image from NASA's Hubble Space Telescope. The hot gas is colour-coded to show temperature, similar to a temperature map of the Earth given in a weather forecast. In MACSJ0717 the coolest gas is shown as reddish purple, the hottest gas is blue and the temperatures in between are purple, (c) [X-ray] NASA, CXC, IfA, C. Ma et al.; [optical] NASA, STScI, IfA, C.

The NASA/ESA Hubble Space Telescope captured this image of NGC 7049 in the constellation of Indus, in the southern sky. A family of globular clusters appears as glittering spots dusted around the galaxy halo. Astronomers study the globular clusters in NGC 7049 to learn more about its formation and evolution. The dust lanes, which appear as a lacy web, are dramatically backlit by the millions of stars in the halo of NGC 7049, (c) NASA, ESA and W.
