A study published in JAMA Network found that a diagnostic strategy combining Transesophageal ultrasound-guided fine needle aspiration (EUS-FNA) and mediastinoscopy can identify more patients with tumor invasion or lymph node metastases, reducing unnecessary thoracotomies by 16%.
A new study published in the New England Journal of Medicine found that prompt ear tube insertion does not improve developmental outcomes in healthy children with middle-ear effusion, contrary to previous findings. The study enrolled 6,350 infants and followed them regularly for three years.
Thomas Kucera, a renowned chemist and advocate for disability rights, will receive the ACS Committee on Chemists with Disabilities' Lifetime Achievement Award. He was the first editor of a landmark publication on teaching chemistry to students with disabilities.
A mouse model of Rett Syndrome displays reduced cortical activity, suggesting a primary cellular defect. The study found that the excitatory-inhibitory balance in the cortex is shifted towards inhibition, which may underlie cognitive, motor, and social symptoms in RTT.
Scientists predict that the Arctic Ocean could be ice-free during the summer months within 100 years due to rapid warming. The report highlights the urgent need for reducing carbon dioxide emissions to mitigate this drastic change.
Researchers at Imperial College London have made a major breakthrough in growing human lungs for transplantation using embryonic stem cells. The cells will be used to repair damaged lungs, particularly in cases of acute respiratory distress syndrome (ARDS).
Researchers at the University at Buffalo have identified microtubules as a critical target for treating Parkinson's disease, which is caused by damage to these intracellular highways. The study found that protecting microtubules can prevent the toxic effects of rotenone on dopamine-producing neurons.
Long-term and regular aspirin use is associated with a significant reduction in colorectal cancer risk, with benefits observed at doses of 14 tablets per week or more. The study found that the risk of colorectal cancer decreased by up to 53% among women who took high-dose aspirin for over 10 years.
A study of 1,193 patients found only 94 received the HAV vaccine, highlighting a significant gap in vaccination rates. Patients with chronic HCV were at risk for severe liver disease and death if infected with HAV, emphasizing the need for increased awareness and vaccination efforts.
Scientists at UC Davis create porous aerogel supports to study artificial membrane systems, aiming to replicate biological membranes. This breakthrough could lead to new insights into how real cell membranes behave in platelet cells that form blood clots.
University of Florida engineers create drones with morphing gull-wing designs to enhance stability and agility in tight city spaces. The innovative technology allows planes to perform sharp turns, spins, and dives, and even land in confined areas, increasing their utility for military operations.
A new study provides direct evidence that the brain's own pain-fighting chemicals play a role in the placebo effect, reducing feelings of pain. Participants who received a sham pain treatment reported increased activity in their mu opioid endorphin system after being told they were receiving a medicine.
Researchers study two entire sea anemone colonies clashing, discovering organized armies of warriors, scouts, and reproductives. Complex behaviors emerge at the group level despite simple organism members.
Scientists at University College London found that the parietal cortex is crucial for detecting changes in a visual scene, explaining why we often miss dramatic changes while concentrating. The discovery sheds new light on 'change blindness,' a phenomenon where people fail to notice large visual changes.
A study published in JAMA found that anesthesia-assisted rapid opioid detoxification is not more effective than other treatment methods and can be associated with health risks. Only 11% of patients continued in treatment for 12 weeks, highlighting the need for effective relapse prevention strategies.
Researchers generate high-resolution dataset of vegetation canopy height, aboveground biomass, and carbon stocks for the US in 2000. The dataset will enable unprecedented quantification of biomass and carbon stocks, improving studies on climate interactions, forest fire mitigation, and wildlife habitat characterization.
A study found a strong relationship between HCV infection and having an anti-HCV positive family member, with the highest incidence rate in children under 10 living in households with an anti-HCV positive parent. Parenteral exposures increased the risk of HCV, particularly in men married to an HCV positive woman.
Researchers have discovered a new function of RNA in the human immune system, which could lead to the development of new treatments for cancer and single-gene genetic diseases. The study found that certain types of RNA are more likely to trigger an immune response due to their chemical modifications.
The MAGIC telescope has tracked a long duration gamma-ray burst, GRB050713A, in the X-ray and very high energy gamma ray band. The observation was made possible by rapid tracking of the telescope, which allowed it to start observing the source just 20 seconds after an alert from the Swift satellite.
A study found that long-term aspirin use lowers the risk of invasive colorectal cancer, especially in those taking high doses for more than 10 years. However, serious gastrointestinal bleeding risk increases with higher doses.
Researchers at Rice University have developed a bacteria that produces succinate, a key chemical precursor for 'green' plastics and drugs. The breakthrough could lead to the creation of sustainable products using renewable resources like grain sorghum.
A recent study has found that obese patients with estrogen-receptor negative (ER-negative) breast cancer are at risk of undertreatment due to reduced chemotherapy doses. The study, published in The Lancet, suggests that obese women with ER-negative disease who receive 85% or more of the recommended first course dose have significantly ...
Researchers at Boston Children's Hospital developed a new screening test, CHr, to detect iron deficiency in infants. The test identified 83% of iron-deficient infants correctly, compared to only 26% with the standard hemoglobin test.
The ACS Scholars Program has reached its 10-year milestone, providing financial support to over 1,600 minority students pursuing degrees in chemistry and related disciplines. The program aims to diversify chemical fields in academia and the workforce, with a focus on African American, Hispanic/Latino, and American Indian students.
A mentoring program aims to improve the retention of college students and faculty from historically underrepresented groups. The study suggests that standardized goal-setting and development skills can aid in this process, as well as discussing genealogy to foster a sense of belonging within the discipline.
Researchers have discovered a genetic finding that may hold the key to unlocking treatments for farsightedness and nearsightedness. The MFRP protein, found in a rare eye disorder called nanophthalmos, regulates eye growth and refraction, making it a promising target for correcting severe refractive errors.
Researchers at CCNY and Lehman College found that magnetic avalanches can propagate like a flame, releasing magnetic energy into a crystal. This phenomenon, known as 'magnetic burning', has potential applications in understanding combustion dynamics.
Researchers investigated the link between bicycle riding and sexual health, finding that high pressures from saddle interface can temporarily occlude penile blood flow. Effective strategies based on ergonometrics and urogenital physiologic principles are needed to reduce risk of erectile dysfunction from cycling.
The ACS Honors 2005 Heroes of Chemistry, who developed treatments for psychosis, myeloid leukemia, and dental disease. They also created cleaner gasoline and materials for smaller computer chips.
