Watching A 'New Star' Make The Universe Dusty
Astronomers were able for the first time to witness the appearance of a shell of dusty gas around a star that had just erupted, and follow its evolution for more than 100 days. This provides the astronomers with a new way to estimate the distance of this object and obtain invaluable information on the operating mode of stellar vampires, dense stars that suck material from a companion.

Energy Drinks Linked To Risk-taking Behaviors Among College Students
Over the last decade, energy drinks -- such as Red Bull, Monster and Rockstar -- have become nearly ubiquitous on college campuses. Now new research validates and expands upon existing concerns about energy drink consumption.

Adult Stem Cells Activated In Mammalian Brain
Adult stem cells originate in a different part of the brain than is commonly believed, and with proper stimulation they can produce new brain cells to replace those lost to disease or injury, a new study has shown.

Early Cessation Of Breastfeeding By HIV+ Women In Poor Countries And Child Survival
Researchers find that abrupt cessation of breastfeeding by HIV+ mothers after the first four months of life did not result in any statistically significant benefit to infants in terms of HIV-free survival at 24 months, compared to those infants who were weaned at an average of 16 months of age.

Smaller Than Small: Ultrahigh-resolution Electron Microscopy Enters Picometer Scale
Scientists have succeeded in precisely measuring atomic spacings down to a few picometers using new methods in ultrahigh-resolution electron microscopy. This makes it possible to find out decisive parameters determining the physical properties of materials directly on an atomic level in a microscope. Progress in research in the area of physics is very frequently connected to an increase in the accuracy of measurements, which help researchers to track natural phenomena.

Internal Medicine Residents May Benefit Most From Time In Clinic
A new approach to internal medicine residency training could improve patient care and physician-patient relationships. Research has shown that residents who spent increased time in outpatient settings as opposed to the hospital delivered a higher quality of care and had more satisfaction in their duties.

Daughters-in-law Help Reduce Depression Among Chinese Elders, But Help From Own Kids Can Increase Depression, Study Finds
In a new twist on the Confucian ideal of filial piety, a study finds that the assistance of daughters-in-law -- but not their own children -- helps mitigate depression among older people in China. Almost two-thirds of the older population in China lives in rural areas, making it the largest concentration of older adults in the world.

Quiet Explosion: Object Intermediate Between Normal Supernovae And Gamma-ray Bursts Found
Astronomers are providing hints that a recent supernova may not be as normal as initially thought. Instead, the star that exploded is now understood to have collapsed into a black hole, producing a weak jet, typical of much more violent events, the so-called gamma-ray bursts. This discovery represents a crucial milestone in the understanding of the most violent phenomena observed in the Universe.

Saving Lives After Natural Disasters With Fast Set-Up Phone Network
A ten-kilo GSM mobile phone network will allow rescue workers to set up communications just hours, or even minutes, after a man-made or natural catastrophe. When disaster strikes communications are often one of the first infrastructures to go down. But it is exactly when effective communications are most desperately needed.

Toxic Chemicals Found In Common Scented Laundry Products, Air Fresheners
A study of top-selling laundry products and air fresheners found the products emitted dozens of different chemicals. All six products tested gave off at least one chemical regulated as toxic or hazardous under federal laws, but none of those chemicals was listed on the product labels.
