Fairbanks, Alaska—A newly excavated archaeological site in Alaska contained the cremated remains of one of the earliest inhabitants of North America. The site may provide rare insights into the burial practices of Ice Age people and shed new light on their daily lives.
University of Alaska Fairbanks archaeologist Ben Potter and four colleagues published their discovery in the Feb. 25 edition of the journal Science.

A study by the University of Salamanca (USAL) has looked into how salaries would differ if immigrants were paid in the same way as Spanish workers according to education and experience. The results show that, in higher salary ranges, Latin American immigrants earn around 20% less than their Spanish counterparts.
A newly published audit report by the International Osteoporosis Foundation (IOF) consolidates information on the status and burden of osteoporosis in 21 countries of Eastern Europe and Central Asia, including the Russian Federation. The landmark report 'Eastern European & Central Asian Regional Audit – Epidemiology, Costs & Burden of Osteoporosis in 2010' shows alarming projections and reveals the poor status of post-fracture care and osteoporosis management in the region.
Like snowflakes or fingerprints, no two quantum dots are identical. But a new etching method for shaping and positioning these semiconductor nanocrystals might change that. What's more, tests at the National Institute of Standards and Technology (NIST) confirm that etched quantum dots emit single particles of light (photons), boosting prospects for powering new types of devices for quantum communications.
Imagine your city isn't as safe as it used to be. Robberies are on the rise, home invasions are increasing and murder rates have nearly doubled in the past three years.
What should city officials do about it? Hire more cops to round up the thugs and lock them away in a growing network of prisons? Design programs that promise more peace by addressing issues like the faltering economy and underperforming schools? Or promote abortions, since proponents claim fewer disadvantaged children reduce crime?
WOODS HOLE, Mass. -- An assessment of coastal change over the past 150 years has found 68 percent of beaches in the New England and Mid-Atlantic region are eroding, according to a U.S. Geological Survey report released today.
Scientists studied more than 650 miles of the New England and Mid-Atlantic coasts and found the average rate of coastal change – taking into account beaches that are both eroding and prograding -- was negative 1.6 feet per year. Of those beaches eroding, the most extreme case exceeded 60 feet per year.
Much of the Mississippi River's sediment load doesn't come from field runoff, according to work by scientists at the U.S. Department of Agriculture (USDA). Instead, the scientists with USDA's Agricultural Research Service (ARS) have confirmed that stream bank collapse and failure can be chief contributors to high sediment levels in the silty streams and rivers that flow into the Mississippi. ARS is USDA's chief intramural scientific research agency.
Americans and Canadians are getting vastly different search results when they look up prescription drug information online, says a study by researchers at the University of British Columbia.
Residents of the United States searching on Google for both brand and generic drug names get directed to the government-run National Library of Medicine. However, Canadians performing the same searches end up getting Wikipedia for generic drug searches, and drug company sites for brand searches, according to the study, published online yesterday by the Annals of Pharmacotherapy.
URBANA – Although declaring bankruptcy was once thought to be a desperate, when-all-else-fails solution, in this new millennium of economic uncertainty, it has become a common option for people who are in deep debt. The question is, can they learn from their mistakes, change their behavior, and recover? A recent study says, yes, with counseling and education.
New research determined that an increase in the severity of hallux valgus, or bunion deformity, progressively reduced both general and foot-specific health related quality of life (HRQOL). Bunion deformity was found in 36% of the study population and occurred more frequently in women and older individuals. Pain in other parts of the body beyond the foot was associated with increased bunion severity.
Almost 600 million years ago, before the rapid evolution of life forms known as the Cambrian explosion, a community of seaweeds and worm-like animals lived in a quiet deep-water niche near what is now Lantian, a small village in south China.
Then they simply died, leaving some 3,000 nearly pristine fossils preserved between beds of black shale deposited in oxygen-free and unbreathable waters.
Civil protests, from peaceful sit-ins at the Pentagon to violent riots in Cairo, nonetheless share some common characteristics. To study how protests evolve in public spaces, Dr. Tali Hatuka, an architect and head of Tel Aviv University's Laboratory of Contemporary Urban Design, has dissected some of the world's most publicized protests — those in Washington, Istanbul, Tel Aviv, Beijing, and Leipzig.
LONDON – A new dinosaur named Brontomerus mcintoshi, or "thunder-thighs" after its enormously powerful thigh muscles, has been discovered in Utah, USA. The new species is described in a paper recently published in the journal Acta Palaeontologica Polonica by an international team of scientists from the U.K. and the U.S.
Older women who used bisphosphonates (medications that prevent loss of bone mass) for five years or more were more likely to experience "atypical" fractures involving the femoral shaft (bone in the leg that extends from the hip to the knee) or subtrochanteric (fractures in the bone just below the hip joint), compared to women with less usage. However, the absolute risk of these "atypical" fractures was low and bisphosphonate use was associated with a reduced risk of typical osteoporotic fractures, according to a study in the February 23 issue of JAMA.
