This suggests that the drug may be used as a temporary solution for young adults struggling with feelings of isolation.
Children who avoided drinking milk in early life have low dietary calcium intakes and poor bone health, including significantly smaller bones and a higher incidence of fractures. The study highlights the importance of increasing calcium intake in growing skeletons to mitigate these effects.
A study by Ohio State University found that procrastinators receive poorer grades in college classes due to lack of self-discipline. The researchers discovered that high procrastinators scored lower in measures of self-regulation and used 'wishful thinking' rationalizations to justify their behavior.
A study found that approximately 40% of rejected lungs might have been suitable for transplantation, highlighting the need for re-evaluation of donor selection criteria. This could lead to an increase in the number of available lungs for transplantation, addressing a potential shortage in lung transplantation.
Researchers at UT Southwestern Medical Center have identified a gene, HDAC9, that limits abnormal heart-muscle growth. The study shows that HDAC9 restricts cardiac growth in response to stress but does not affect normal growth during development or exercise.
A new instrument, PILS, automates aerosol sampling and provides more detailed time-dependent information on atmospheric pollutants. This allows scientists to make frequent measurements, revealing previously unknown morning and afternoon peaks in pollutant levels.
Researchers are studying the manatee virus to develop an approach to fighting cervical cancer in humans. The manatee immune system is being studied to gain a better understanding of diseases like HIV/AIDS.
A Global Development Organisation is necessary to overcome barriers to global development, including fragmentation, strategic incoherence, and resource overconsumption. The organisation would aim to set standards for best practice, avoid duplication of work, and hold institutions accountable for their impact on development.
Despite expected global warming impacts, a NASA study reveals an increase in Antarctic sea ice coverage, with the area lengthening by at least one day per year spanning around 5.6 million square kilometers.
A gene found in some people of African descent may increase the chance of irregular heartbeat (arrhythmia), which can be lethal in rare cases. Precautions such as taking alternative diuretics and staying hydrated during exercise may help reduce risk, say researchers.
A study found that childhood body mass index (BMI) values are strongly linked to adult overweight or obesity. Younger children with higher BMI-for-age had a greater risk of becoming overweight as adults. The authors recommend monitoring children in the ≥ 85th percentile of BMI for age to prevent weight management issues.
Researchers found that male lions are intimidated by longer manes, while females prefer darker-maned males. Darker manes also correlate with higher testosterone levels, which may be an advantage for attracting mates and defending territories. Despite this, there is no correlation between mane length and temperature regulation.
Researchers at University of Illinois Chicago have discovered a way to render cancer cells more susceptible to immunological attacks and chemotherapy. By inserting the E1A gene into malignant cells, they can prevent tumor cells from blocking immune defenses, paving the way for new treatments.
Researchers found HIV integrates into human chromosomes near active genes, which are triggered by the virus itself. This targeting specificity could improve gene therapies by leveraging a retrovirus's efficiency.
A systematic review found that ear thermometry is not a reliable method for measuring infants' body temperature, with wide individual differences and potential overestimation or underestimation of temperatures. This raises concerns about the accuracy of fever detection and precise temperature measurement in clinical settings.
A new study found that the increased pain following exercise in osteoarthritis patients is short-lived, typically subsiding by evening. This insight can help patients cope with temporary increases in pain and stick to exercise programs for long-term benefits.
A study led by Mark T. Keating found that 13.2% of African-Americans carry an altered form of the SCN5A gene, linked to prolonged contraction of heart muscle cells and arrhythmia risk. The variant can be detected through simple tests, allowing for preventive measures such as avoiding certain medications and monitoring potassium levels.
Dr. Sharon Cobb is leading the development of a Materials Science Research Rack on the International Space Station, which will allow scientists to study material properties in low-gravity conditions. The rack's furnaces will be used to melt and solidify various materials, with data collected for characterization on Earth.
A study highlights the need for UK childhood screening for amblyopia, finding that effective treatment can prevent incapacitating vision loss later in life. The research also suggests a lower risk of visual improvement among adults, emphasizing the importance of early detection and treatment.
Researchers found that 40% of rejected lungs could have been candidates for transplantation, more than doubling the number of potentially suitable donor lungs. The study highlights the need for a prospective assessment of selection of donors for lung transplantation to potentially save thousands of lives.
A study of pregnant women found that those consuming high levels of DHA during pregnancy had infants with more mature sleep patterns, characterized by lower active to quiet sleep ratios and less sleep-wake transition time. Breastfed infants also showed improved neurological development compared to formula-fed infants.
