A survey of 81 school districts in 11 states found that few schools are using effective anti-drug programs, with the most common programs being unproven. Effective programs such as Reconnecting Youth and Life Skills Training are available but often lack funding and teacher training.
Researchers at HHMI discovered that crossing two related mouse species results in abnormalities in gene imprinting and growth abnormalities in hybrid offspring. The study found that disruptions in growth contribute to speciation by reflecting a rapidly evolving divergence between species.
Researchers have developed a method to deliver nucleotides directly into tumor cells, assembling them on their own. This approach may lead to new treatments with improved efficacy and reduced side effects for various types of cancer.
A University of Washington study found that real-world job training can significantly reduce the likelihood of ex-felons returning to prison. The successful trainees also earned more money and worked longer hours than those in dead-end jobs.
A study found that surgeons in Ontario have differing opinions on when to perform surgery on children with ear infections, citing varying factors. The researchers surveyed 17 clinical and social factors, but only six were agreed upon, highlighting the need for a revised approach to addressing this common Canadian procedure.
A new drug, modafinil, has been shown to effectively treat fatigue in multiple sclerosis patients, with over 85% of participants able to identify the active ingredient. The study found that modafinil improved fatigue severity and had minimal side effects, making it a promising first-line treatment for MS patients.
Researchers found that TRAIL causes catastrophic damage to human liver cells, but not to liver cells from mice and nonhuman primates. The study's findings indicate that results of standard preclinical tests may mislead investigators about an agent's safety for use in humans.
Researchers studied microbes living in Yellowstone National Park's hot springs to better interpret samples from Mars for signs of life. They developed a systematic model for travertine deposition, which could aid in identifying ancient microbial life.
A unique residential laboratory is being used to study the impact of technology on domestic lifestyle, with a focus on enhancing home life and family connections. Researchers aim to discover technology combinations that can unobtrusively enhance lifestyle in the home.
A new software program developed by Emory researchers uses data from 840 previous patients to predict outcomes in new patients. The genetic adaptive model has an accuracy rate of 76 percent and can help determine a patient's chances of cancer recurrence after treatment, guiding doctors towards the best treatment option.
Researchers found a new class of drugs called selective apoptotic anti-neoplastic drugs (SAANDs) that can safely slow tumor growth in men with advanced prostate cancer. The study showed significant results with minimal side effects.
Researchers at the University of Illinois have developed a new membrane filtration system that enhances the nutritional value of coproducts, including gluten meal and gluten feed. This could lead to increased demand for corn and make ethanol production more profitable.
Researchers at MIT have discovered a key role for the N-methyl-D-aspartate (NMDA) receptor in fetal development of the respiratory system. The study found that abnormal activity of this receptor may lead to problems in newborns, such as Sudden Infant Death Syndrome and breathing difficulties.
Researchers have identified three recurrent BRCA1 mutations in Polish breast-ovarian cancer families, suggesting founder mutations. These mutations, 5382insC, C61G, and 4153delA, account for 82% of the study's findings, enabling more efficient screening and diagnosis.
Researchers at Vanderbilt University have designed and constructed a small robotic 'bug' that can scuttle more than half a mile on a single battery charge. The robot, which is about three inches long and weighs two ounces, uses an unusual material called piezoelectric ceramic to achieve its motion.
Researchers developed a novel fabrication technique that uses magnetic actuation to assemble large arrays of three-dimensional microstructures. The method involves casting individual components in place and using a magnetic field to fold them into shape.
Researchers found that mountainous areas can receive dramatically different amounts of pollutants and excess nutrients, creating 'hotspots' with high ecological sensitivity. The study suggests that estimates of atmospheric deposition must take into account complex mountain landscapes, elevations, aspect, and vegetation type.
Researchers found that inhibiting triglyceride synthesis, a key step in fat regulation, results in obesity resistance in mice. The study suggests that blocking DGAT-mediated triglyceride synthesis may be a potential strategy for treating obesity.
The UNC-CH survey found that only a third of schools use Life Skills Training, and a quarter use Project ALERT, two programs proven to be effective in preventing adolescent drug experimentation. Many coordinators lack full-time staff to devote to drug prevention, with only 25% having one or more employees doing so.
The UC Berkeley team has developed a set of principles that apply to animal locomotion of all kinds, from running to flying. Their research has led to breakthroughs in robot design, ergonomics, and even computer animation, with potential applications in fields like engineering and Pixar Animation Studios.
Tornado researcher Andrew Pazmany heads to the Great Plains to track supercells and determine conditions that enable F4/F5 tornadoes. He will use a modified marine radar to analyze storm structures and distances.
A new study by Oregon State University found that postmenopausal women who participate in a long-term fitness regimen can prevent significant bone loss in the hip. The exercise program, which includes weighted vests and jumping exercises, showed a significant reduction in bone density loss compared to a control group.
Researchers found that a 200 milligram-per-day dose of the narcolepsy drug modafinil successfully controlled fatigue in patients with MS, a disease that attacks the nervous system. The study involved 72 patients with severe fatigue and MS, who reported significantly less fatigue when taking the 200 mg dose compared to the placebo.
Researchers at University of Illinois find organelle with acidocalcisome properties, crucial for malaria parasite's existence, and propose using pyrophosphate analogs to target it. This discovery may lead to new treatment options against rapidly resistant malaria.
