Seismic images show dinosaur-killing meteor made bigger splash
01-23-2008 · EurekAlert!The most detailed 3-D seismic images yet of the Chicxulub impact crater may modify a theory explaining the "KT Extinction Event" that wiped out most life on Earth, including the dinosaurs. According to research appearing in Nature Geosciences, the asteroid landed in deeper water than previously assumed and therefore released about 6.5 times more water vapor into the atmosphere, possibly making it deadlier by altering climate and generating acid rain.

- New algorithms from UCSD improve automated image labeling
03-29-2007 · EurekAlert!
Electrical engineers from UC San Diego have made progress on a different kind of image search engine -- one that analyzes the images themselves. This approach may be folded into next-generation image search engines for the Internet; and in the shorter term, could be used to annotate and search commercial and private image collections.

- Portrait of a dramatic stellar crib
12-21-2006 · EurekAlert!
A new, stunning image of the cosmic spider, the Tarantula Nebula and its surroundings, finally pays tribute to this amazing, vast and intricately sculpted web of stars and gas. The newly released image, made with ESO's Wide Field Imager on the 2.2-m ESO/MPG Telescope at La Silla, covers 1 square degree on the sky and could therefore contain four times the full moon.

- Decoding gene expression in cancer tumors using noninvasive imaging
05-21-2007 · EurekAlert!
By correlating images of cancerous liver tissue with gene expression patterns, a research team led by a radiologist at the University of California, San Diego School of Medicine has developed tools that may some day allow physicians to view a CT image of a cancer tumor and discern its genetic activity.

- New Study Explores Role Of Theater In Maya Political Organization
10-10-2006 · ScienceDaily
Magnificent stone sculptures of Classic Maya culture (AD 250-900) have long fascinated archaeologists and the general public alike. But what did the scenes depicted in these monuments mean in their society? In an article to appear in the October 2006 issue Current Anthropology, Takeshi Inomata (University of Arizona) argues that these images commonly show acts of public performance conducted by rulers, revealing the prominent role which state theater played in Maya political organization.

- Brown team finds crucial protein role in deadly prion spread
01-23-2007 · EurekAlert!
Brown University biologists have made another major advance toward understanding the deadly work of prions, the culprits behind fatal brain diseases such as mad cow and their human counterparts. In new work published online in PLoS Biology, researchers show that the protein Hsp104 must be present and active for prions to multiply and cause disease.

- Rise of dinosaurs in Late Triassic more gradual than once thought
07-19-2007 · EurekAlert!
The ancestors of dinosaurs seemed to disappear before the dinosaurs took over the Earth 200 million years ago, suggesting to many that dinosaurs were so successful that they rapidly out-competed their ancestors and drove them extinct. New fossil finds in New Mexico, however, show that this was not true -- dinosaurs and their ancestors lived side by side for 15-20 million years in the Late Triassic before the dinosaur precursors vanished.

- Photo favourite: ATV rendezvous simulation
11-13-2006 · European Space Agency (ESA)
A choice from our ESA photo galleries
Tests conducted at Val de Reuil, France, to simulate the rendezvous of the Automated Transfer Vehicle (ATV) with the International Space Station (ISS). Sensors mounted on an articulated industrial robotic arm (image) acted as the ATV, whilst a 120-tonne mobile platform represented the ISS. During simulations the platform was made to approach the robotic arm in a motion identical to the one expected when the real vehicles rendezvous in space next year.

02-19-2007 · EurekAlert!
A report of the American Psychological Association (APA) released today found evidence that the proliferation of sexualized images of girls and young women in advertising, merchandising and media is harmful to girls' self-image and healthy development.

- The celestial whirligig
02-23-2007 · EurekAlert!
Comet McNaught, the Great Comet of 2007, has been delighting those who have seen it with the unaided eye as a spectacular display in the evening sky. Pushing ESO's New Technology Telescope to its limits, a team of European astronomers have obtained the first, and possibly unique, detailed observations of this object. Their images show spectacular jets of gas from the comet spiralling several thousands of kilometres into space, while the spectra reveal the presence of sodium in its atmosphere, something seen very rarely.

- A novel way found to prevent protein plaques implicated in Alzheimer's
11-18-2007 · EurekAlert!
For unknown reasons a protein called amyloid beta aggregates into toxic plaques in the brain, killing neurons. These plaques are one of the hallmarks of Alzheimer's disease. Now two new animal studies show for the first time that the deadly transformation of amyloid beta into plaques can be prevented through an interaction between amyloid beta and another protein called cystatin C.
