Sandia is testing five innovative arsenic-removal technologies at a geothermal spring in Socorro, New Mexico, as part of the Arsenic Water Technology Partnership. The pilot test aims to develop cost-effective water treatment solutions for small communities impacted by the new EPA standard.
A study of over 9,600 participants found that those who were severely obese in young adulthood had significantly higher Medicare charges at age 65 compared to non-overweight peers. The average annual Medicare charges for severely obese individuals were $6,192 more than for non-overweight men and $5,618 more than for non-overweight women.
Scientists have developed a new method for crystallizing proteins, which could lead to the creation of effective drugs for diseases such as cystic fibrosis and Alzheimer's. The improved method uses a thinner sponge-like structure to bind proteins together more easily.
The Idaho National Laboratory has recognized five scientists, William Apel, James Delmore, Paul Meakin, David Petti, and Herschel Smartt, as its first-ever Laboratory Fellows. They were selected based on their professional knowledge, scientific achievements, and national technical leadership.
The study, led by Dr. Miguel Nicolelis, demonstrates the ability to distinguish patterns of brain activity in awake animals, including fleeting changes during sleep stages. The new analytical technique enables unprecedented insights into the healthy brain and neurological diseases like epilepsy and Alzheimer's.
The UC Riverside Extension will provide support to trained teachers and day care providers in San Bernardino County with funding from First 5 California and First 5 San Bernardino. The organization will offer tuition assistance, training, and educational resources to help improve early childhood education.
A study by Northwestern University researchers found that average annual and cumulative Medicare charges are significantly higher for obese individuals, with severe obesity resulting in costs of up to $175,000. The study highlights the urgent need for preventive measures to address obesity and reduce healthcare costs among older adults.
Scientists have determined how a specific protein blocks DNA replication, providing a key to designing targeted cancer therapies. By understanding the structure of this protein, researchers may also develop new forms of antibiotics.
Researchers find that bulimia often co-occurs with dysthymia, a lower-level depression. Chronic low self-esteem and prolonged mood disturbances contribute to the development of bulimia. The study suggests that therapists can assess for dysthymia in bulimic patients and choose targeted treatments to combat both disorders.
A study of 642 men aged 60+ found that those with higher bone lead levels in the tibia were more likely to develop cataracts. The researchers suggest that reducing lead exposure could help decrease the global burden of cataract, a condition affecting over 40% of blindness cases.
A study published in the American Journal of Roentgenology found that increased bone marrow fat is an independent marker of bone weakening. The ratio of bone marrow fat to bone mineral density was higher in healthy individuals and lower in those with signs of bone weakening.
The NIDCR-launched study aims to detect unique patterns of gene expression in oral bacterial communities that predict periodontal diseases. The researchers will store biological information in a searchable online database, allowing for more precise diagnosis and treatment.
U of MN researchers have developed a new approach to adult cord blood transplantation, achieving high engraftment rates and low complications. The treatment uses combined use of two cord blood units from different donors, offering potentially life-saving therapy to patients previously denied treatment.
Researchers have discovered that marine snails and humans share identical cellular mechanisms for learning and memory, which could lead to breakthroughs in understanding age-related memory loss and developing interventions for people with memory disorders. The study may also shed light on the role of protein synthesis in long-term memory.
Research found a high correlation between tumor responses based on tumor density and biologic changes in gastrointestinal tract tumors. Monitoring only tumor size to judge treatment effectiveness proved unreliable, highlighting the need to evaluate biologic changes as well.
Researchers at Children's Hospital of Philadelphia studied 25 newborns born with congenital heart defects and found significantly lower cerebral blood flow, associated with periventricular leukomalacia, a condition linked to cognitive problems. The study suggests that abnormal neurological conditions may play a role even before surgery.
Researchers found that transplanted bone marrow cells reduced liver fibrosis in mice treated with carbon tetrachloride. The treatment also improved survival rates and increased serum albumin levels, suggesting a new concept for treating liver fibrosis.
A study found that minority teens perceive their own ethnic groups using more drugs than others, but this perception is influenced by their sense of identity. In contrast, White youth tend to underestimate the prevalence of drug use among other racial groups.
Scientists report that marine benthic diversity in Laurentia recovered to pre-extinction levels within 5 million years, nearly 15 million years sooner than suggested by global compilations. This rapid recovery suggests that the region operated differently from the globe as a whole.
A study found breast MRI had a high sensitivity of 88.1% for detecting breast cancer, but moderate specificity of 67.7%. The imaging modality did not significantly improve outcomes for patients with mammographically or clinically suspicious lesions.
Researchers at Idaho National Laboratory have achieved a major advancement in producing hydrogen from water using high-temperature electrolysis, enhancing efficiency to 45-50%. This technology has the potential to reduce greenhouse gas emissions and fossil fuel consumption.
Researchers expand the ABCD rule to recognize changing characteristics of early melanomas, especially nodular melanomas. The new guideline aims to improve detection and diagnosis of this aggressive form of skin cancer.
A study published in JAMA found that MRI can accurately detect breast cancer with a high sensitivity rate of 88.1%, but its effectiveness decreases when ruling out malignancies. The technology is most beneficial for patients with difficult-to-interpret mammograms.
Researchers found significant ethnic differences in NAFLD prevalence, with striking variations among Hispanics, whites, and blacks. Hepatic steatosis was more common in Hispanics and less common in blacks, highlighting fundamental differences in lipid homeostasis.
The UNC study found that schools with a Tobacco-Free School policy had significantly fewer instances of smoking at football games than those without such a policy. Compliance varied widely between schools and from game to game, but was highest when schools clearly communicated their policy using signs and public announcements.
Scientists at Penn State have observed extended chains of phenylene molecules that align and interact without forming chemical bonds, paving the way for controlling growth and assembly of molecules. This discovery could lead to manipulating nanostructured materials with unprecedented precision.
A study found that pharmaceutical sales representatives have limited influence on physician prescribing behavior, despite significant spending on detailing and free samples. Physicians rely on alternative sources of information, such as scientific papers and colleagues, which outweigh the persuasive power of sales representatives.
A new study suggests that resveratrol in red wine can prevent the excessive production of collagen in heart cells, leading to a stiffening of the heart muscle and reduced blood pumping efficiency. Drinking moderate amounts of red wine may offer protective effects against hypertension and heart failure.
Researchers identified a shortfall of IDE protein in Alzheimer's patients and found a cause-effect relationship between insulin signaling and increased production of IDE. A low-fat diet high in fish and soy was shown to increase production of IDE, suggesting a potential protective effect against Alzheimer's disease.
The American Academy of Ophthalmology published a comprehensive collection of 60 case studies covering diverse ophthalmic topics including sebaceous carcinoma, refractive errors, glaucoma, and more. The studies provide valuable insights into the diagnosis and management of various eye conditions.
