A study published in Child Development found that instructors who use hand gestures while teaching math problems outperform those without gestures. Students who learned from gesture videos performed better on tests compared to those who learned from speech-only videos, with improved retention over time.
Researchers have created a numeric model of the chromosome that supports experimental data and provides a hypothesis on the bundle's function. The model identifies regions with specific genes, contradicting the chaotic view of the chromosome as a randomly entangled thread.
Researchers found no association between vaccine exposure and autism in a study of over 300 children with ASD and 750 without, contradicting long-standing parental concerns about vaccine safety.
A Texas physician has successfully performed a groundbreaking robotic laparoscopic procedure to tighten a pregnant patient's incompetent cervix. The innovative technique, which utilizes the da Vinci Si robotic surgical system, allowed for precise stitching with minimal scars.
A randomized, controlled trial found that consuming monounsaturated fats in vegetable oils like canola oil lowered abdominal fat by 1.6 percent compared to other oil blends. This reduction in belly fat may decrease metabolic syndrome risk factors and heart disease risk.
The Society for Industrial and Applied Mathematics (SIAM) has announced its 2013 Class of Fellows, comprising 33 renowned mathematicians. These individuals were recognized for their outstanding research and service to the mathematical community.
A new study reveals obstructive sleep apnea is associated with ADHD-like behaviors and other adaptive learning problems in children. Children with persistent sleep apnea were seven times more likely to have parent-reported learning problems.
Researchers at the University of Sheffield have developed a tactile helmet that uses ultrasound sensors to detect distances and provide fire-fighters with additional information. The technology could also be useful for people with visual impairments, acting as an additional sense to guide users.
Astronomers use NASA's Swift satellite to estimate the size of comet ISON's icy nucleus based on water and dust production rates. The team finds that the comet is shedding large amounts of dust but relatively little water, indicating that other volatile materials are fueling its activity.
A recent study published in the Journal of the National Cancer Institute found that estrogen plus progestin use is associated with an increased risk of breast cancer. The study suggests that mortality from breast cancer may be higher for women using this combined hormonal therapy.
A study published in the Journal of the National Cancer Institute found that estrogen plus progestin use is associated with an increased risk of breast cancer incidence. However, survival after diagnosis did not differ between users and non-users, suggesting higher mortality rates among hormone therapy users.
A new study published in Psychology of Women Quarterly found that Asian-American students, particularly males, excel in math and science, while Latino and African American males underperform. The research also shows that female students' perceptions of their abilities in STEM fields are influenced by societal stereotypes.
Researchers have discovered a new species of freshwater snail in Skadar Lake, an ancient lake on the Balkan Peninsula. The discovery highlights the importance of conserving this ecosystem due to its high level of endemism and vulnerability to eutrophication and pollution.
A new study by University of Arizona entomologists reveals that the pyramid strategy for genetically modified crops may not be as durable as previously assumed. The research found that critical assumptions underlying the strategy do not always apply, and that some degree of cross-resistance between toxins can reduce its effectiveness.
Researchers at Joint BioEnergy Institute develop new strategy to enhance polysaccharide deposition in plant cell walls, reducing lignin content and improving sugar release. This breakthrough could increase cell wall content for the pulping industry, bioenergy applications, and improve crop yields.
Researchers studied detrital zircon Hf isotopic compositions to connect the Alexander terrane in Canada with northern Caledonian granitoids. In California, a kinematic analysis of mélange fabrics near San Simeon reveals sinistral slip on the Nacimiento fault zone. The Western Alps also experienced short-lived fast erosional exhumation ...
A new mathematical model, based on biased assimilation, shows that polarization stems from people's tendency to accept evidence supporting their opinions and discredit opposing views. The model, developed by Stanford researchers, aims to create Internet-based social systems that counteract polarization.
