Using data from humans and other mammals, a team of scientists including researchers from the Santa Fe Institute has developed one of the first quantitative models that explains why sleep times across species and during development decrease as brains get bigger. Crucially, the model identifies a sharp transition at around 2.4 years of age, where sleep patterns change in humans as the primary purpose of sleep shifts from reorganization, which is essentially learning, to repair.
A blood protein test could detect the severity of head trauma in under 15 minutes, according to a recent study.
A team of researchers from LSU Health New Orleans Neuroscience Center of Excellence and the University of Copenhagen provides the first evidence that patients with ocular hypertension may exhibit superior antioxidant protection that promotes resistance to the elevated intraocular pressure associated with glaucoma.
Researchers from the Masonic Medical Research Institute (MMRI), the Precision Cardiology Lab (PCL) of the Broad Institute at MIT and Harvard, Bayer USA, Massachusetts General Hospital, and University of Pennsylvania collaborated to uncover some pressing questions about the biology of the heart. While understanding the mechanisms causal to human heart disease remain active areas of research for many scientists, important knowledge gaps about its composition and function remain unknown.
Independent group leaders Eleanor Scerri and Denise Kühnert of the Max Planck Institute for the Science of Human History (MPI-SHH) have teamed up with other colleagues from the institute and beyond to comment on the future of field-based sciences in a COVID-19 world. The piece outlines the epidemiological characteristics of SARS-CoV-2, details its effects on field-based sciences and identifies how working practices can be remodeled to overcome the challenges brought on by the virus.
A team of researchers from the USDA Forest Service, Arkansas State University, and other organizations conducted a study over two seasons at the Port of Savannah, Georgia to inventory nonnative plant seeds that entered the U.S. on refrigerated shipping containers; determine their viability as potential invasive species; and propose strategies for reducing risk to native ecosystems and agricultural commodities.
Protected areas are the most important tool for curbing biodiversity loss, but a lack of field data hampers efforts to measure their effectiveness. Scientists have now used records collated by thousands of citizens to show that protected areas contribute significantly to the conservation of rare and threatened birds across tropical forests hotspots. Protected areas achieve these positive outcomes by preventing deforestation and by retaining the quality of the remaining forest habitats. Published in Nature Communications.
New research from The University of Texas at Austin suggests people too often opt to send email or text messages when a phone call is more likely to produce the feelings of connectedness they crave.
The trial determined the safety, reliability, and feasibility of the device in this stroke population. 'We found that the ReStore provided targeted assistance for plantarflexion and dorsiflexion of the paretic ankle, improving the gait pattern,' explained Dr. Nolan, senior research scientist in the Center for Mobility and Rehabilitation Engineering Research at Kessler Foundation. 'This is an important first step toward expanding options for rehabilitative care for the millions of individuals with mobility impairments caused by ischemic and hemorrhagic stroke.'
The LIGO Scientific Collaboration and the Virgo Collaboration recently announced the discovery of GW190521, the most massive gravitational wave binary observed to date, and Rochester Institute of Technology scientists played an important role in identifying and analyzing the event.
