A recent study found that nearly 60% of males and over two-thirds of females met diagnostic criteria for mental or substance use disorders, highlighting a significant concern for the high rates of depression and dysthymia among detained youth.
Researchers found that childhood exposure to nature leads to a greater appreciation of the outdoors and interest in environmental careers. This has implications for educators and policymakers, as it can increase support for land preservation and environmental conservation.
A study by Gerianne Alexander found that male and female monkeys showed similar preferences for 'boy' and 'girl' toys as human children, suggesting innate preferences. The findings suggest that perceptual cues attract males to active play objects like cars and balls, while females prefer toys with nurturing functions.
The new digital tomosynthesis system provides high-resolution cross-section images with reduced structure overlap, making lesions easier to detect. This technology has the potential to revolutionize breast cancer detection and diagnosis, allowing for earlier interventions.
The US Navy has established a new center for nanoscience innovation in defense, which will transfer knowledge from universities to the industry. The center aims to advance nanoscale systems and devices for advanced technology, including spintronics and quantum information processing.
Researchers have developed a web-based project to familiarize drivers with Boston's new Big Dig routes. The Web Big Dig Drive provides detailed information on signage, pavement markers, and side barriers, helping commuters and travelers adjust to the changes ahead of time.
A multicenter study published in Depression and Anxiety found that mecamylamine, a nicotine antagonist, significantly improved behavioral and emotional symptoms in children co-diagnosed with Tourette's syndrome and major depression. The study suggested that mecamylamine stabilizes mood by inhibiting nicotinic receptors.
Research shows that memories in the amygdala and hippocampus can be reactivated and require protein synthesis for restoration, contradicting long-held theories of memory storage. Dr. Nader's findings also explain false memory syndrome by revealing the biological basis of reconsolidation.
A comparative study of plants and birds on oceanic islands found that invasive species outnumber native species, causing extinctions but increasing overall diversity. The total number of land bird species has remained relatively unchanged despite the loss of native species.
Researchers describe three patients with valvular heart disease linked to long-term pergolide therapy, highlighting the need for further studies to determine the association. The Mayo Clinic team recommends discontinuing pergolide if valvular disease is detected, emphasizing the importance of monitoring patients
Researchers at Dana-Farber Cancer Institute found that combination therapy of cytarabine, daunorubicin, and Mylotarg achieved complete remission in 83% of evaluable participants. The treatment was well-tolerated, with no significant increase in side effects.
The Office of Naval Research has developed a new missile called the Affordable Weapon, designed to carry a significant payload to a target several hundred miles away. Equipped with GPS navigation and line-of-sight data links, the Affordable Weapon can fly directly to its target or loiter until directed by a forward observer.
A Mayo Clinic study found that adenocarcinoma of the lung is more strongly associated with smoking than previously recognized. Women who smoked a pack of cigarettes a day for 20 to 39 years had a higher risk of developing lung cancer, particularly adenocarcinoma.
Researchers have identified two genes responsible for defects in vitamin B12 metabolism, which can lead to accumulation of methylmalonic acid. This breakthrough could enable DNA testing for carriers and early prenatal diagnosis, providing hope for families affected by the disease.
A new model of team care, IMPACT, significantly improved depression treatment outcomes in older adults compared to usual care. Patients assigned to IMPACT reported greater reductions in depression symptoms and improvements in daily functioning.
A study found that individuals with lower incomes and education levels are more likely to have severe arthritis but less likely to be on waiting lists for joint replacement surgery. Women from lower socio-economic backgrounds are also less likely to discuss joint replacement with their doctors.
Researchers found that administering recombinant human erythropoietin (rHuEPO) resulted in a 19% reduction in red blood cell transfusion. The study showed improved hemoglobin levels and reduced exposure to RBC tranfusions, with potential benefits including morbidity and mortality reductions.
Researchers will investigate brain structures controlling responses to rewarding stimuli and their role in mood regulation. The goal is to develop new treatments for depression, which affects 20% of Americans.
The Center for Nanoscience Innovation for Defense (CNID) has been created to rapidly transition research in the nanosciences into defense applications. The center is being led by Robert C. Haddon and will use CNID funds to establish basic infrastructure for nanotechnology research at UCR.
A recent study published in the Journal of the American Medical Association found that internet filters can effectively distinguish between health information and pornography when set at moderate levels. However, highly restrictive settings may block a significant portion of essential health sites, while still providing excellent porn ...
