Researchers used genome-wide scanning to uncover genetic causes of Hirschsprung disease, a complex disorder resulting from subtle gene mutations. The study identified two key genes, RET and EDNRB, which must co-exist to cause the disease, providing new insights into its underlying mechanisms.
A study by Cornell University researchers found that urban areas in the US now have an average of 10 more very warm nights a year than rural areas, which has significant implications for heat problems. The growth was highest on the East Coast, with cities like Miami and Los Angeles showing the most extreme temperature trends.
Perlmutter's discovery of the universe's accelerating expansion using supernovae as standard candles revolutionized our understanding of the cosmos. His work, done through the Supernova Cosmology Project, has far-reaching implications for our knowledge of the fundamental nature of the universe.
Women with endometriosis have a higher prevalence of autoimmune inflammatory diseases, hypothyroidism, fibromyalgia, chronic fatigue syndrome, allergies, and asthma. A 10-year delay between symptom onset and diagnosis is common, prompting doctors to consider endometriosis in girls and women with pelvic pain.
Research suggests that drinking water can improve a person's ability to stand and reduce the likelihood of fainting, particularly for individuals who donate blood. Healthy participants were tested using tilt-table testing, with results showing an average increase of 40.9 minutes in tolerated standing time when hydrated.
USC researchers are testing a prototype 'e-textile' that can detect faint sounds, specifically distant vehicle movements on future battlefields. The fabric functions as a supersensitive detection array and can be deployed in various ways, such as a parachute or camouflage net.
Researchers examine the mechanisms underlying inactivation of BRCA1 and its impact on patient management. The study assesses the potential usefulness of BRCA1 as a prognostic tool and predictive marker for response to different classes of drugs.
The international Type 1 Diabetes Genetics Consortium will collect and analyze genetic data from 2,500 families worldwide to identify genes contributing to the disease. The consortium aims to clarify the complex interaction between genetics and environment in type 1 diabetes.
A recent study found that nonoxynol-9 spermicide may increase the risk of HIV-1 infection in women due to vaginal lesions caused by frequent use. In contrast, low-frequency use showed no harm or benefit. The findings highlight the need for alternative vaginal microbicides.
SMU and UNC researchers discovered that the E(Z) protein silences genes by modifying a specific chromatin protein, a mechanism found to be conserved in both humans and Drosophila. This breakthrough sheds light on how Polycomb-group proteins regulate gene expression during development.
Researchers at University of Melbourne warn of potential risks in pesticide control due to widespread resistance discovered in Drosophila melanogaster fly species. The gene Cyp6g1 confers resistance by producing more protein that breaks down pesticides, posing significant challenges for future pest management options.
A population-based study of 2,786 diabetic and non-diabetic postmenopausal women found that HRT had a positive effect on blood levels of fats and glucose. Diabetic women on HRT had significantly lower fasting levels of total cholesterol and higher levels of beneficial high-density lipoprotein.
A study found that azithromycin improved forced expiratory volume in one second's exhalation (FEV1) by around 5% in some children with cystic fibrosis. The drug was well-tolerated and showed no significant difference in quality-of-life assessments compared to placebo.
Researchers at Stanford Medicine identified a protein fragment called gliadin as the cause of gluten intolerance. They also proposed using a dietary enzyme to break down the fragment into harmless bits, offering hope for future treatment.
Key findings from a study suggest that patients prioritize personal service, therapist listening skills, and clear explanations over facility amenities. Researchers surveyed over 1,868 participants and found that adequate time spent on individual patient care is vital for patient satisfaction.
Researchers found that black single mothers in rural Georgia with good self-esteem and optimism implemented effective parenting practices, leading to higher levels of self-regulation in their children. This resulted in better academic performance, social skills, and reduced delinquency.
Researchers at the University of Melbourne discovered a key player in the brain's response to low glucose levels, shedding light on how diabetes and hypoglycemia are regulated. By studying Neuropeptide Y, scientists hope to develop new treatments for these conditions.

The treatment has the potential to be an alternative to traditional surgery for selected patients, particularly those wishing to preserve their fertility.
A double-blind, randomized controlled trial found that taking aspirin at bedtime significantly reduced the risk of preterm labor and preeclampsia in pregnant women with high blood pressure. The study also showed significant weight gains in babies born to mothers who took aspirin at night.
