A research study, in which Universidad Carlos III de Madrid took part, has concluded that traditionally irrigated Mediterranean landscape has suffered an important loss of the cultural and ecological patrimony that it holds, especially as a result of the modernization of the traditional watering networks established throughout this countryside.

BOSTON, Feb. 28, 2011 – A gel developed to protect against HIV during vaginal sex produced a strong antiviral effect when used in the rectum, according to an early-phase study presented today at the 18th Conference on Retroviruses and Opportunistic Infections (CROI). The results, based on rectal tissue biopsies sampled from HIV-negative men and women who used the product daily for one week, provide the first-ever evidence that tenofovir gel could help reduce the risk of HIV from anal sex, even though the vaginal gel formulation may not be optimal for rectal use.
It is known that education decreases the incidence of cardiovascular disease. New research published in BioMed Central's open access journal BMC Public Health demonstrates that education is also correlated with lower blood pressure and a decrease in other factors which influence health such as alcohol, smoking and weight gain.
Researching animals in the wild can be challenging, especially if it involves a rare or elusive species like the giant panda or the clouded leopard. To remedy this, scientists rely heavily on camera traps—automated cameras with motion sensors. Left to photograph what passes in front of them, the cameras record the diversity and very often the behavior of animals around the world.
Music is listened in all known cultures. Similarities between human and animal song have been detected: both contain a message, an intention that reflects innate emotional state that is interpreted correctly even among different species. In fact, several behavioral features in listening to music are closely related to attachment: lullabies are song to infants to increase their attachment to a parent, and singing or playing music together is based on teamwork and may add group cohesion.
At the 3rd International Conference on innovative approaches in Head and Neck Oncology (ICHNO), Dr Hanna Rahbek Mortensen and colleagues at hospitals and institutes in Denmark presented results from a large prospective trial, the DAHANCA 6 & 7 study. The study, conducted across the country, investigated risk factors for developing dysphagia (swallowing dysfunction), after undergoing radiotherapy treatment for a head & neck cancer.
A strong link between victimization experiences and substance abuse has been discovered by researchers at the University of Illinois at Chicago.
The correlation is especially prevalent among gays, lesbians and bisexuals -- more so than in heterosexuals, says Tonda Hughes, professor and interim head of health systems science in the UIC College of Nursing. Hughes is lead author of the study, published in the journal Addiction.
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.
Discovery of oldest northern North American human remains provides new insights into Ice-Age culture
A newly excavated archaeological site in Alaska contains the cremated remains of one of the earliest inhabitants of North America. These remains may provide rare insights into the burial practices of Ice Age peoples, while shedding new light on their daily lives, according to a paper published Feb. 25 in 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.
