Oct. 13, 2010 — Nutrition rating systems and symbols on the fronts of food packaging would be most useful to shoppers if they highlighted four nutrients of greatest concern – calories, saturated fat, trans fat, and sodium – says a new report from the Institute of Medicine. These food components are routinely overconsumed and associated most strongly with diet-related health problems affecting many Americans, including obesity, heart disease, high blood pressure, Type 2 diabetes, and certain types of cancer.

Astronomers using the South Pole Telescope report that they have discovered the most massive galaxy cluster yet seen at a distance of 7 billion light-years. The cluster (designated SPT-CL J0546-5345) weighs in at around 800 trillion Suns, and holds hundreds of galaxies.
In research published this week in PLoS Medicine, Stephen Freedman (University of Toronto) and colleagues performed a cost analysis of the emergency department administration of oral ondansetron to children with dehydration and vomiting secondary to gastroenteritis and found that this treatment could provide substantial economic, as well as clinical, benefit.
Scientists from the Niels Bohr Institute have been studying distant galaxies, which are among the most active star-forming galaxies in the Universe. They form around 1,000 new stars a year – a 1,000 times more than our own galaxy, the Milky Way. The findings have been published in Monthly Notices of the Royal Astronomical Society.
A University of Colorado at Boulder space dust counter designed, tested and operated by students that is flying aboard NASA's New Horizons mission to Pluto now holds the record for the most distant working dust detector ever to travel through space.
COLUMBUS, Ohio -- A giant star in a faraway galaxy recently ended its life with a dust-shrouded whimper instead of the more typical bang.
Ohio State University researchers suspect that this odd event -- the first one of its kind ever viewed by astronomers – was more common early in the universe.

What happens to sunscreens when they are exposed to sunlight? And how is the skin affected by the degradation products that form? This has been the subject of research at the University of Gothenburg and Chalmers University of Technology that will be presented at the upcoming dermatologist conference in Gothenburg.
At 11 a.m. EDT on Oct. 8, Otto strengthened into a hurricane, becoming the eighth hurricane of the Atlantic Ocean season. NASA's Aqua satellite and the NOAA GOES-13 satellite captured images of Otto as he intensified.
NASA's James Webb Space Telescope continues to make significant progress, successfully completing a series of sunshield vent tests that validate the telescope's sunshield design.
There are few places on Mars lower than this. On the left of this image, the floor of Melas Chasma sinks nine kilometres below the surrounding plains. New images from ESA's Mars Express highlight the complex history of this enormous martian canyon.
In an experiment exploring the chemical processes that might be going on in the hazy atmosphere enshrouding Saturn's largest moon, a team of scientists discovered a variety of complex organic molecules – including amino acids and nucleotide bases, the most important ingredients of life on Earth.
The molecules discovered include the five nucleotide bases used by life on Earth to build the genetic materials DNA and RNA: cytosine, adenine, thymine, guanine and uracil, and the two smallest amino acids, glycine and alanine. Amino acids are the building blocks of proteins.
Saturn's icy moon Enceladus should not be one of the most promising places in our solar system to look for extraterrestrial life. Instead, it should have frozen solid billions of years ago. Located in the frigid outer solar system, it's too far from the sun to have oceans of liquid water -- a necessary ingredient for known forms of life -- on its surface.
