A recent study found that HIPAA compliance severely affected patient participation in long-term outcome studies, with a significant drop from 96.1% to 38.5%. This reduction resulted in a less representative sample of patients, which could bias study results.
A study published in The Lancet found that subdural hemorrhages in full-term babies are rare and typically resolve on their own. The research suggested that forceps-assisted deliveries and other trauma during birth may increase the risk of bleeding, but even then, it is usually not a cause for concern.
Researchers at NIST have developed a new method for producing uniform, self-assembled nanocells using micrometer-size channels. These nanocells can be controlled to specific sizes and are ideal for encapsulating medicine, leading to more accurate drug delivery.
The MIT 'Weird Fields' contest utilizes creative visuals to help students grasp abstract electromagnetism concepts. By exploring vector fields through interactive software, students can better comprehend the physics behind electromagnetic forces.
Research found that how couples manage parenting responsibilities when their child is 6 months old affects the quality of their marriage when their child is 3 years old. Couples who had a good relationship with each other as infants but struggled with parenting conflicts were more likely to have poorer couple relationships later on.
A team of NIST and IBM researchers has quantified 'electrical capture defects' in hafnium oxide chips, which can drain currents and hinder transistor operation. By applying a voltage pulse and measuring current, the scientists identified critical locations where these defects occur near the silicon substrate-hafnium oxide interface.
Scientists recommend preserving contaminated DOE sites as is, rather than undergoing costly remediation, to protect wildlife, biodiversity, and regional air and water quality. This approach would also reduce remediation costs and minimize public health risks.
A recent study examines seroprevalence of non-pneumonic SARS-CoV infections in general population and healthcare workers. The findings suggest that non-pneumonic infections are more common than SARS-CoV pneumonia, shedding light on possible explanations for cases with no obvious contact to other patients.
Researchers found a link between olfactory dysfunction and excess tau proteins in brain structures important for smelling. The study used genetically engineered mice to evaluate the effect of tau protein overexpression on smell perception.
Scientists have pinpointed a new cancer gene target, PIK3CA, which is mutated in 32% of colon cancers and may be involved in tumor growth. The study suggests that targeted therapies could be more effective with fewer side effects, leading to personalized cancer treatment.
Researchers identified four genetic variants strongly associated with type 2 diabetes in Finnish and Ashkenazi Jewish populations. The variants cluster in the regulatory region of the HNF4A gene, influencing insulin secretion in response to glucose.
The National Institute of Standards and Technology (NIST) has approved standards for electronic methods used in measuring live animals, carcasses, and individual cuts. The new standards aim to increase consistency and confidence in measurements across technologies, benefiting equipment manufacturers, producers, packers, and consumers.
Researchers found that subjects viewing 'before and after' ads indicated a strong anti-fat bias and believed weight is more easily controllable than those who viewed only the 'before' or 'after' pictures. The study suggests that such biases can influence further weight and eating disorder psychopathology.
Researchers discovered a link between the Endothelial NO Synthase gene and Alevolar Capillary Dysplasia (ACD), a fatal lung disease affecting newborns. The study found that mice lacking this gene developed major defects in lung development, mirroring human cases of ACD.
Scientists have developed a novel fabrication technique to study charge transport in organic crystals, resulting in the highest recorded mobility in an organic semiconductor. The method eliminates exposure of fragile surfaces to conventional processing, allowing for pristine crystal samples to be used for device fabrication.
A study of 300 former child soldiers found nearly all experienced traumatic events, including physical and sexual abuse. The study highlights the need for stronger intervention by the UN to prevent children from being used as soldiers in conflicts.
Researchers successfully doped C60 molecules with potassium atoms using atomic precision, increasing their electric charge and altering molecular orbital states. This breakthrough offers a new way to control electronic properties of individual molecules, with potential applications in nanotechnology and electronics.
Researchers successfully demonstrated precise control over molecular electronic properties using a scanning tunneling microscope. They added up to seven potassium atoms to a single buckyball molecule, altering its electrical properties.
A peptide, MUC7 12-mer, has shown promise for treating drug-resistant fungal strains. When combined with a protease inhibitor cocktail, its anti-microbial action was significantly increased.
A new study supports the use of PET scans in early diagnosis of Alzheimer's disease, particularly in its early stages. The study identifies a new PET technique that can clearly identify brain connections altered by Alzheimer's, leading to higher accuracy in diagnosing the condition.
A research team led by Dr. Howard Lipshitz discovered that a protein linked to mammalian embryo implantation also plays a role in tumour metastasis in fruit fly development. The study found a surprising level of similarity between the proteins in flies and mammals, with potential implications for understanding human disease.
Researchers at the University of California - Davis have cloned the VRN2 gene in wheat, which controls vernalization and plays a crucial role in the crop's adaptation to different environments. The study provides valuable insights into breeding strategies for improving wheat varieties through manipulation of flowering times.
A NIST study identifies a potential source of error in the automotive industry's use of surface roughness data to predict friction. The researchers developed an improved analytical approach that can help automakers incorporate lighter weight materials and improve fuel efficiency.
A team of scientists discovered microbes that produce nanometer-scale crystals of extraordinary length, using polymer fibers as templates. The discovery may provide key insight into biomineralization, the process that produces bone, teeth, and shell.
A new biomarker, EPCA, has been discovered that can detect prostate cancer earlier than traditional methods. The marker is expressed in the tumor and throughout the prostate in men with prostate cancer.
Physicists at NIST used a highly sophisticated spectrometer to measure light wavelengths, providing 10 times better resolution than similar instruments. This improvement is expected to help the semiconductor industry create smaller circuits.
A UCI study reveals that newborn neurons in the adult brain mature by growing neural signaling appendages similar to those found in developing brains. This finding may aid in understanding how stem cells can be used to treat neurological diseases.
Researchers at Duke University Medical Center have discovered a gene link between juvenile polyposis and high blood pressure syndrome. The study suggests that patients with the intestinal disorder should undergo genetic screening for vascular defects, as they are at risk of experiencing severe nosebleeds or strokes.
