Pear psylla is a cicada-like pest with a vexing tendency to develop resistance to insecticides. But now, a new weapon could be in the works.
Agricultural Research Service (ARS) and University of California-Riverside (UCR) scientists have jointly identified a key component of the female psylla's chemical sex attractant, or pheromone, which could set the stage for luring amorous males to their doom.
Although women have a longer life expectancy, they experience a much greater prevalence of disability in old age than men do. This is the main conclusion of the study published in the latest issue of the Journal of Women's Health.
The extinction of woolly mammoths and other large mammals more than 10,000 years ago may be explained by the same type of cascade of ecosystem disruption - they mean you and me - that is being implicated today in the global decline of predators such as wolves, cougars and sharks, life scientists report July 1 in BioScience.
Then, as now, the cascading events were originally begun by human disruption of ecosystems, a new study concludes, but around 15,000 years ago the problem was not the loss of a key predator, but the addition of one — human hunters with spears.
Researchers from Boston University School of Medicine (BUSM) have identified two molecules that when activated by drugs, can inhibit a number of specific aspects of HIV transmission. These findings, published July 1 in the open-access journal PLoS Pathogens, may lead to therapies that target mucosal HIV transmission.
Just about everyone agrees that sustainability – cutting energy use, reducing carbon emissions and, in general, keeping the Earth green – is a good thing. But why do we think that? Do we support sustainability for the right reasons?
These are among the questions that Michigan State University's Michael Nelson addresses in a paper published this month in the journal Bioscience titled "Sustainability: Virtuous or Vulgar?"
Washington, DC—A new research symposium investigates the interrelationships between terrorism and governmental respect for human rights, regarding both how political authorities respond to terrorist violence and how human rights abuses can predict subsequent terrorist attacks. Responding to a lack of systematic evidence and granular data on the linkages between these two areas, the symposium addresses issues both domestic and international, ranging from public opinion on torture to the Guantanamo detention facility, sexual abuse in Israeli prisons, and the American profile abroad.
While 20/20 vision is a symbol of visual acuity, between now and the year 2020, more and more people will experience some extent of vision loss due to age-related macular degeneration (AMD) and other sight-robbing diseases.
STANFORD, Calif. — Leading stem cell researchers from institutions around the world are issuing warnings about unproven stem cell therapies being marketed on the Internet and have launched a website to educate and protect patients seeking such treatments. Often conducted outside of the United States, most of these therapies have little or no benefit — and can be dangerous as well as costly.
3,200-year-old bronze tablet is part of a linchpin that held the wheel of a battle chariot in place.
SAN FRANCISCO, CA– Although it is already one of medicine's most successful transplant procedures, doctors continue to seek ways to improve corneal transplants. Now, for the first time, a team of German and British researchers have confirmed that failure and rejection of transplanted corneas are more likely in patients whose eyes exhibit abnormal vessel growth, called corneal neovascularization, prior to surgery. The meta-analysis report appears in July Ophthalmology, the journal of the American Academy of Ophthalmology.
CHAMPAIGN, Ill. — A worldwide survey of more than 136,000 people in 132 countries included questions about happiness and income, and the results reveal that while life satisfaction usually rises with income, positive feelings don't necessarily follow, researchers report.
Boston, MA -- More than two billion people worldwide do not have adequate access to surgical treatment, according to a new study from the Harvard School of Public Health (HSPH). The researchers also found that people living in high-income regions have far greater access to operating theatres (surgery sites) than those living in low-income regions and that surgical facilities in low-income settings often lack essential equipment.
There are 8.3 million children who are 5 years and younger living in Tanzania. With limited access to formal education, can media intervention make a positive and significant impact on what these children learn?
The vast majority of Americans interviewed in a new national poll believe winter is the most dangerous time for driving, but the truth is this coming Fourth of July weekend often is the deadliest time.
