- 12/8/6 21:14
Microbes, sponges, and worms -- the side effects of pollution and heavy fishing -- are adding insult to injury in Kenya's imperiled reef systems, according to a recent study.
Preschool children who can pay attention more likely to finish college: Early reading and math not predictive of college completion
- ScienceDaily
- 12/8/6 21:14
Young children who are able to pay attention and persist on a task have a 50 percent greater chance of completing college, according to a new study. Surprisingly, achievement in reading and math did not significantly predict whether or not the students completed college. And the good news for parents and educators, the researchers said, is that attention and persistence skills are malleable and...
Researchers unlock secret of the rare 'twinned rainbow'

Seafood, wild or farmed? The answer may be both
- ScienceDaily
- 12/8/6 21:14
Most people think of seafood as either wild or farmed, but in fact both categories may apply to the fish you pick up from your grocery store. An article recommends that when a combination of seafood production techniques are used, this be acknowledged in the marketplace.
Black drink: Evidence of ritual use of caffeinated brew at Cahokia
- ScienceDaily
- 12/8/6 21:12
People living 700 to 900 years ago in Cahokia, a massive settlement near the confluence of the Missouri and Mississippi Rivers, ritually used a caffeinated brew made from the leaves of a holly tree that grew hundreds of miles away, researchers report.
Correlation between injection wells and small earthquakes discovered
- ScienceDaily
- 12/8/6 21:12
Most earthquakes in the Barnett Shale region of north Texas occur within a few miles of one or more injection wells used to dispose of wastes associated with petroleum production such as hydraulic fracturing fluids, according to new research. None of the quakes identified in the two-year study were strong enough to pose a danger to the...
Epilepsy drug reverses memory loss in animal model of Alzheimer's disease
- ScienceDaily
- 12/8/6 21:12
Scientists have discovered that an FDA-approved anti-epileptic drug reverses memory loss and alleviates other Alzheimer's-related impairments in an animal model of the disease.
Generic language helps fuel stereotypes
- ScienceDaily
- 12/8/6 21:12
Hearing generic language to describe a category of people, such as "boys have short hair," can lead children to endorse a range of other stereotypes about the category, a new study has found.
Limits of microbial life in an undersea volcano: Third of Earth's organisms live in rock and sediments
- ScienceDaily
- 12/8/6 21:12
By some estimates, a third of the Earth's organisms by mass live in our planet's rocks and sediments, yet their lives and ecology are almost a complete mystery. Microbiologists have just revealed the first detailed data about a group of methane-exhaling microbes that live deep in the cracks of hot undersea...
Major breakthrough in macular degeneration
- ScienceDaily
- 12/8/6 21:12
Researchers have made an exciting finding in the "dry" form of age-related macular degeneration known as geographic atrophy (GA). GA is an untreatable condition that causes blindness in millions of individuals due to death of retinal pigmented epithelial cells.
Possible muscle disease therapeutic target found
- ScienceDaily
- 12/8/6 21:12
The study of muscular system protein myostatin has been of great interest to researchers as a potential therapeutic target for people with muscular disorders. Although much is known about how myostatin affects muscle growth, there has been disagreement about what types of muscle cells it acts upon. New research narrows down the field to one likely type of...
Researchers peek at the early evolution of sex chromosomes
- ScienceDaily
- 12/8/6 21:12
Two new studies offer insight into sex chromosome evolution by focusing on papaya, a multimillion dollar crop plant with a sexual problem (as far as growers are concerned) and a complicated past.
New study defines the genetic map of the Jewish diasporas
- ScienceDaily
- 12/8/6 21:11
A new genetic analysis focusing on Jews from North Africa has provided an overall genetic map of the Jewish Diasporas. The findings support the historical record of Middle Eastern Jews settling in North Africa during Classical Antiquity, proselytizing and marrying local populations, and, in the process, forming distinct populations that stayed largely intact for more than 2,000...
USGS science goes to Mars

- 12/8/6 21:03
With the Mars rover Curiosity's successful landing Sunday, Aug. 5, at 10:32 p.m. PDT, U.S. Geological Survey scientists continue their strategic role in the Mars Science Laboratory (MSL), the most advanced mission yet to explore whether the Red Planet has ever offered environmental conditions favorable for microbial...
NASA's Curiosity rover caught in the act of landing
- ScienceDaily
- 12/8/6 20:19
An image from the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter captured the Curiosity rover still connected to its 51-foot-wide (almost 16 meter) parachute as it descended towards its landing site at Gale Crater.
Increased productivity, not less energy use, results from more efficient lighting
- ScienceDaily
- 12/8/6 19:51
Improvements in lighting -- from candles to gas lamps to electric bulbs -- historically have led to increased light consumption rather than lower overall energy use by society, researchers argue in a new article.
Infants of overweight mothers grow more slowly
- ScienceDaily
- 12/8/6 19:51
Babies born to overweight mothers gain less weight and grow more slowly than those born to normal-weight mothers, a new study has found. But they do catch up, meaning that pediatricians should refrain from boosting their nutrition, which could make matters worse, experts say.
New bird species discovered in 'cloud forest' of Peru

A colorful, fruit-eating bird with a black mask, pale belly and scarlet breast – never before described by science – has been discovered following an expedition to the remote Peruvian Andes.
Airborne technology helps manage elephants
- ScienceDaily
- 12/8/6 19:08
For years, scientists have debated how big a role elephants play in toppling trees in South African savannas. Tree loss is a natural process, but it is increasing in some regions, with cascading effects on the habitat for many other species. Using high resolution 3-D mapping, scientists have for the first time quantitatively determined tree losses across savannas of Kruger National Park. They...
