Telescopes Explain Mysterious 17th Century Explosion

March 24, 2015 7:00 am | by ESO | News | Comments

New observations made with telescopes reveal that the star that European astronomers saw appear in the sky in 1670 was not a nova, but a much rarer, violent breed of stellar collision. It was spectacular enough to be easily seen with the naked eye during its first outburst, but the traces it left were so faint that very careful analysis using submillimeter telescopes was needed before the mystery could be explained.


Tastier, Healthier Chocolate Possible

March 24, 2015 7:00 am | by ACS | News | Comments

Chocolate has many health benefits— it can potentially lower blood pressure and cholesterol and reduce stroke risk. But just as connoisseurs thought it couldn't get any better, there's this tasty new tidbit: researchers have found a way to make the treat even more nutritious— and sweeter.  


Squid Inspire Stickers that May Help Soldiers

March 24, 2015 7:00 am | by ACS | Videos | Comments

Squid are the ultimate camouflage artists, blending almost flawlessly with their backgrounds so that unsuspecting prey can't detect them. Using a protein that's key to this process, scientists have designed "invisibility stickers" that could one day help soldiers disguise themselves, even when sought by enemies with tough-to-fool infrared cameras.


Jupiter's Journey Shaped Our Strange Solar System

March 24, 2015 7:00 am | by UC Santa Cruz | News | Comments

Jupiter may have swept through the early solar system like a wrecking ball, destroying a first generation of inner planets before retreating into its current orbit, according to a new study. The find helps explain why our solar system is so different from the hundreds of other planetary systems that astronomers have discovered in recent years.  


Gene Influences Body Shape, Disease Risks

March 24, 2015 7:00 am | by Duke Univ. | News | Comments

Scientists have known for some time that people who carry a lot of weight around their bellies are more likely to develop diabetes and heart disease than those who have bigger hips and thighs. But what hasn't been clear is why fat accumulates in different places to produce classic "apple" and "pear" shapes.


Viruses, Archaea Self-mutate to Survive

March 23, 2015 3:00 pm | by UC Santa Barbara | News | Comments

Strange creatures live in the deep sea, but few are odder than archaea, primitive single-celled microorganisms that go to great lengths to survive the most extreme environments on the planet. Now, scientists discovered something odder: a virus that seemingly infects methane-eating archaea living beneath the ocean’s floor. Stranger still, this virus selectively targets one of its own genes for mutation and, moreover, some archaea do too.


Professional Help Ups Healthy Food Consumption in Schools

March 23, 2015 3:00 pm | by The JAMA Network Journals | News | Comments

Fruit and vegetable selections in school meals increased after students had extended exposure to school food made tastier with the help of a professional chef and after modifications were made to school cafeterias, including signage and more prominent placement of fruits and vegetables, but it was only chef-enhanced meals that also increased consumption.


How Much STEM Homework is Too Much?

March 23, 2015 3:00 pm | by American Psychological Association | News | Comments

When it comes to adolescents with math and science homework, more isn't necessarily better— an hour a day is optimal— but doing it alone and regularly produces the biggest knowledge gain.


We Flush Valuable Metals, Critical Elements

March 23, 2015 3:00 pm | by ACS | News | Comments

Poop could be a goldmine— literally. Surprisingly, treated solid waste contains gold, silver and other metals, as well as rare elements such as palladium and vanadium that are used in electronics and alloys. Now, researchers are looking at identifying the metals that are getting flushed and how they can be recovered. This could decrease the need for mining and reduce the unwanted release of metals into the environment.


Popular Sweetener Key to Treating Aggressive Cancers

March 23, 2015 3:00 pm | by ACS | News | Comments

Saccharin, the artificial sweetener that is the main ingredient in Sweet 'N Low, Sweet Twin and Necta, could do far more than just keep our waistlines trim. According to new research, this popular sugar substitute could potentially lead to the development of drugs capable of combating aggressive, difficult-to-treat cancers with fewer side effects.  


New Rice May Stem Rising Obesity

March 23, 2015 3:00 pm | by ACS | News | Comments

Scientists have developed a new, simple way to cook rice that could cut the number of calories absorbed by the body by more than half, potentially reducing obesity rates, which is especially important in countries where the food is a staple.  

Earth Has Hidden Layer

March 23, 2015 3:00 pm | by Univ. of Utah | News | Comments

By crushing minerals between diamonds, a study has suggested the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets three times stiffer. The discovery may explain a mystery: why slabs of Earth's sinking tectonic plates sometimes stall and thicken 930 miles underground.


Foreign Wild Horses May Save Czechoslovakian Biodiversity

March 23, 2015 8:29 am | by Associated Press, Karel Janicek | News | Comments

Twenty-five years ago it was a military zone where occupying Soviet troops held exercises. Today it's a sanctuary inhabited by wild animals that scientists hope will improve biodiversity among local plants as well as save endangered species. A herd of 14 wild mares from Britain's Exmoor National Park were moved in January to the former Milovice military base, 22 miles northeast of Prague, the Czech capital.


Popular Weed Killer is One Likely Cause of Cancer

March 23, 2015 8:17 am | by Associated Press, Joshua Goodman | News | Comments

The new labeling of the world's most-popular weed killer as a likely cause of cancer is raising more questions for an aerial spraying program in Colombia that is the cornerstone of the U.S.-backed war on drugs. A research arm of WHO has reclassified the herbicide glyphosate as a result of convincing evidence the chemical produces cancer in lab animals and more limited findings it causes non-Hodgkin's lymphoma in humans.


Science is Not Just About Facts: Readers React

March 23, 2015 7:00 am | by Michelle Taylor, Editor-in-Chief | Blogs | Comments

Earlier this month, I wrote an editorial based on the release of a study that revealed stark differences between the general public and scientists on science-related issues. It received a lot of attention, garnering comments and sparking debate. Here are a few of the best comments and reaction to them.
