Mystery spiral arms explained?
Using a trio of space observatories, astronomers may have cracked a 45-year old mystery surrounding two ghostly spiral arms in the galaxy M106 (NGC 4258).   view more (2007-04-11)

NASA Telescope Reveals Nearby Galaxy's Invisible Arms
A new image from NASA's Galaxy Evolution Explorer shows that a galaxy once thought to be rather plain and old is actually endowed with a gorgeous set of young spiral arms.   view more (2005-07-25)

Hubble's sweeping view of the Coma Galaxy Cluster
The NASA/ESA Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of Galaxies, one of the densest known galaxy collections in the Universe.   view more (2008-06-10)

Questioning the humanity of countries that supply arms
Trading in arms is highly detrimental to the health of mothers and children in the poor countries where armed conflict occurs. But do the powerful arms trading countries want to address the problems they are causing? Researchers in this week's Christmas issue of the BMJ reveal the unethical... view more (2002-12-18)

Battle of the sexes leads to a biological arms race
Boxes of chocolate and Valentine cards won't get you far in the animal world, where courting is considerably tougher. New research confirms earlier beliefs: an evolutionary "battle of the sexes" can lead to a biological arms race between males and females. We all know that males and... view more (2002-02-14)

Caltech astronomers describe the bar scene at the beginning of the universe
Bars abound in spiral galaxies today, but this was not always the case. A group of 16 astronomers, led by Kartik Sheth of NASA's Spitzer Science Center at the California Institute of Technology, has found that bars tripled in number over the past seven billion years, indicating that spiral galaxies... view more (2008-07-30)

Three satellites needed to bring out 'shy star'
An international team of scientists has uncovered a rare type of neutron star so elusive that it took three satellites to identify it   view more (2005-07-14)

Unveiling the Secret of a Virgo Dwarf Galaxy
Dwarf galaxies may not be as impressive in appearance as their larger brethren, but they are at least as interestingfrom a scientific point of view. And sometimes they may have hidden properties that will only be found by means of careful observations, probing the signals of their stars at the... view more (2000-05-03)

Scientists Probe Black Hole's Inner Sanctum
How does matter spiral its way to the center of a galaxy and into the mouth of a supermassive black hole?   view more (2006-01-10)

Galactic survey reveals a new look for the Milky Way
With the help of NASA's Spitzer Space Telescope, astronomers have conducted the most comprehensive structural analysis of our galaxy and have found tantalizing new evidence that the Milky Way is much different from your ordinary spiral galaxy.   view more (2005-08-17)

EARLY DETECTION OF LUNG CANCER POSSIBLE WITH CAT AND PET SCANS (pp 588, 593)
Issue 23 August 2003 Embargoed 0001 h (London time) 22 August 2003. Preliminary results from a European study in this week's issue of THE LANCET show that combined use of spiral computed tomography (CT) and positron emission tamography (PET) scanning can reliably detect early lung cancer.... view more (2003-08-20)

NASA sees into the eye of a monster storm on Saturn
NASA's Cassini spacecraft has seen something never before seen on another planet - a hurricane-like storm at Saturn's south pole with a well-developed eye, ringed by towering clouds.   view more (2006-11-10)

Discovery of a molecular mechanism underlying limb architecture
A genetic study performed by Dr. Marie Kmita, a researcher at the Institut de Recherches Cliniques de Montréal (IRCM), in collaboration with Drs Basile Tarchini and Denis Duboule of the University of Geneva in Switzerland, sheds light on the origins of the architecture of arms and legs.   view more (2006-10-26)

The Purple Rose of Virgo
ntil now NGC 5584 was just one galaxy among many others, located to the West of the Virgo Cluster. Known only as a number in galaxy surveys, its sheer beauty is now revealed in all its glory in a new VLT image. Since 1 March, this purple cosmic rose also holds the brightest stellar explosion of the... view more (2007-03-28)

Hubble sees the graceful dance of 2 interacting galaxies
A pair of galaxies, known collectively as Arp 87, is one of hundreds of interacting and merging galaxies known in our nearby Universe. Arp 87 was originally discovered and catalogued by astronomer Halton Arp in the 1970s. Arp's Atlas of Peculiar Galaxies is a compilation of astronomical photographs... view more (2007-10-31)

Suppression of FOXO1a gene might kill resistant ARMS tumors
The loss of function of a gene called FOXO1a plays an important role in the development of the most common cancer of soft tissues in children, and restoring the function of that gene in cancer cells suppresses that cancer.   view more (2005-09-22)

Lung cancer screening encouraged for smokers with a strong family history of the disease
To detect invasive lung cancer in its early stages, researchers urge current and former smokers who have a strong family history of the disease to take a lung function test and undergo screening with spiral computed tomography.   view more (2006-01-03)

Survival rates appear lower for scalp and neck melanoma than for other sites
Individuals with melanoma on their scalp or neck appear less likely to survive for five or 10 years than those with melanoma at other sites, according to a report in the April issue of Archives of Dermatology, one of the JAMA/Archives journals.   view more (2008-04-22)

Scientists find 'pinwheels' in Quintuplet cluster
Discovery of pinwheel-shaped dust spirals around two of the mysterious cocoon stars in the Quintuplet cluster tells scientists for the first time that they contain a duo of stars instead of just one.   view more (2006-08-21)

UGA astronomers discover surprising shortage of hot gas in famed spiral galaxy NGC 1068
Spiral galaxies are the glitter of the universe. These systems of stars, dust, gas and plasma are held together by gravity but seem to pinwheel across the darkness of space.   view more (2006-06-06)

Robotic device appears useful for surgical removal of cancer involving the tonsils
A new robotic surgery technique appears promising for the removal of cancer involving the tonsil region, according to a report in the December issue of Archives of Otolaryngology-Head & Neck Surgery, one of the JAMA/Archives journals.   view more (2007-12-18)

Immigrant Sun: Our star could be far from where it started in Milky Way
A long-standing scientific belief holds that stars tend to hang out in the same general part of a galaxy where they originally formed. Some astrophysicists have recently questioned whether that is true, and now new simulations show that, at least in galaxies similar to our own Milky Way, stars such... view more (2008-09-16)

Brittlestar provides new model for stem cell research
The brittlestar, Amphiura filiformis, is a close relative of the starfish and can regenerate lost arms in a matter of weeks.   view more (2006-04-10)

Rac 1 and 2, two proteins essential to triggering of the immune response
The dendritic cells act as the body's sentries, standing guard around the clock. As soon as they detect a potential enemy, they alert the T cells, whose role is to defend the body. At the Institut Curie, CNRS researchers in an Inserm laboratory have filmed the encounter of dendritic cells and T... view more (2004-08-23)

How the octopus forms an elbow
The octopus arm is extremely flexible. Thanks to this flexibility-the arm is said to possess a virtually infinite number of "degrees of freedom"-the octopus is able to generate a vast repertoire of movements that is unmatched by the human arm.   view more (2006-04-18)
