The study will use a database of over 11,000 subjects and develop new statistical tools to classify substance dependence more effectively.
A new study found that infants who can resettle themselves after waking up are more likely to sleep for prolonged periods at night. By three months of age, most infants develop this ability, which is associated with longer sleep durations and reduced crying at night.
Rockefeller University scientists have uncovered crucial steps in the nuclear pore complex's dilation and constriction mechanism. Transport factor karyopherin initiates ring dilation by stabilizing Nup58, allowing larger molecules to pass through.
The study highlights seven potential benefits of pairing territorial use rights in fisheries (TURFs) and marine reserves, including increased fish abundance, reduced IUU fishing, and improved conservation. TURFs grant exclusive access to designated areas, promoting local ownership and conservation measures.
Researchers found that autologous bone marrow stem cells significantly reduced cranial pressure and therapeutic intensity in TBI patients, decreasing neurointensive care time by nearly 60%.
Abelardo Colon and Jennifer Gill from the University of Puerto Rico won the top honors with their video explaining a new method for disinfecting drinking water using a nanodiamond powder. The process has promising results, reducing fecal E. coli colonies and increasing density.
Researchers from the UCL Institute of Child Health and Great Ormond Street Hospital found non-invasive prenatal testing to be highly effective and acceptable to parents. Over 2,500 women underwent NIPT for high and medium risk pregnancies with Down's syndrome, showing a sharp decrease in invasive tests and increased detection rates.
Researchers at NHGRI create high-throughput gene editing system in zebrafish, allowing for simultaneous targeting and mutation of multiple genes. This method accelerates discovery of gene function and identification of disease genes in humans.
