Researchers at Ohio State University found a link between major stressors during pregnancy and the development of autism in children. The study, which included over 200 mothers, showed that stress levels for mothers of autistic children were nearly twice those of other mothers.
A woman convicted of murdering three children by suffocation shares her perspective on how intense grief and a desire for control led to her actions. The authors argue that empathy from professionals could have prevented these tragedies.
Researchers found that people who felt a sense of purpose in life were more likely to experience well-being and less fearful of death. In contrast, extrinsically religious participants tended to fear death and avoid thinking about it. The study suggests the need for intrinsic motivation through spiritual nurturing and self-reflection.
A new suite of experiments will be delivered to the International Space Station by Space Shuttle Endeavour, broadening scientific research onboard the orbiting space laboratory. The experiments are expected to lead to insights in various fields such as bone disorder treatments, plant growth, and cancer cell formation.
A recent study by the American Academy of Periodontology found that 48% of teeth receiving periodontal surgery improved prognosis, while only 12% in non-surgical treatment groups did. The study emphasized the importance of individual teeth assessment for optimal results.
Researchers created a tiny computer using DNA molecules and enzymes, performing a billion operations per second with high accuracy. The device can be programmed to perform simple tasks and may pave the way for future computers that can operate within the human body.
A new study published in Psychosomatic Medicine found that women with higher educational attainment have less calcification of the arteries, indicating a lower risk of developing heart disease. The analysis of 308 postmenopausal women revealed an inverse linear trend between calcium deposits and education level.
A study of 633 HIV-positive participants found that sociodemographic factors significantly affect their nutritional adequacy. Gay men, those with higher household incomes and educational attainment, were more likely to meet the Recommended Daily Allowances for nutrients. In contrast, individuals with lower incomes, fewer children at ho...
A study published in the American Journal of Clinical Nutrition found that obese women converted carbohydrates to fat at a faster rate than lean women. This increased conversion was observed even when both groups were overfed with carbohydrate-rich diets, suggesting an intrinsic genetic potential for de novo lipogenesis.
The UCLA Basic Plasma Science Facility has been awarded a $4.8 million grant to conduct controlled experiments on plasma, a fourth state of matter. The Large Plasma Device (LAPD) machine allows physicists to create and analyze superheated, energized gas, with potential applications in fusion energy, computer chips, and waste destruction.
Severe periodontal disease poses significant threats to pregnant diabetics, exacerbating the condition and pregnancy outcomes. The American Academy of Periodontology recommends routine periodontal exams for pregnant diabetic women.
The novel depicts institutional and domestic abuse against children, including Oliver's mistreatment in a workhouse and Nancy's abuse by her pimp Bill Sykes. Dickens identifies recognized parental risk factors for abuse, such as substance abuse, domestic violence, and mental health problems, which are now acknowledged by modern research.
Researchers found that astronauts' endogenous circadian pacemaker (ECP) loses its influence after about 90 days in space, leading to reduced sleep quality and duration. This could jeopardize performance on longer missions like those to Mars.
Researchers at UCSD and VA San Diego Healthcare System discovered a natural antibiotic peptide called cathelicidin, which inhibits microbe growth and plays a crucial role in mammalian innate immunity. The study provides hope for developing new treatments and a blood test to identify individuals susceptible to bacterial infections.
A questionnaire surveyed junior doctors in two London teaching hospitals and found that nearly all were aware of post-exposure prophylaxis (PEP) but many lacked knowledge on its use. The study highlights the need for improved education on PEP among medical professionals to prevent occupationally acquired HIV infections.
A study found that ethnic differences affect the relationship between family environment and teen gang involvement, with black youth benefiting from more controlling parents and white/other youth increasing their involvement with gangs. Gang intervention programs should address both peer and parent relationships to be effective.
A scoring system characterized the men from pessimist to optimist, with optimistic men having a lower risk of coronary heart disease. Despite this protective effect, the researchers found no difference in mortality rates between optimistic and pessimistic men.
A recent study by Ohio State University researchers found that gay men tend to weigh the benefits and drawbacks of revealing their HIV status, with over half disclosing to family and 63% telling friends. The top reasons for disclosure included keeping others safe and seeking understanding.
The US FDA has approved Tracleer (bosentan) tablets as the first oral treatment for patients with pulmonary arterial hypertension. The medication works by blocking the effects of endothelin on blood vessels, improving exercise capacity and reducing symptoms. Regulatory reviews are ongoing in several countries.
