In this study of 2,574 participants with obstructive sleep apnea, compared with participants with objective sleep duration of at least seven hours, those sleeping less than seven hours had higher risks of all-cause mortality independent of apnea-hypopnea index. Further studies would be needed to investigate health benefits of extending sleep length among people with obstructive sleep apnea with short sleep duration.
Bahareh Behkam and collaborators have received a $2 million grant from the National Science Foundation (NSF) to continue their fight against airborne pathogens. An associate professor of mechanical engineering, Behkam and her team will use the funding to further develop engineered living systems for indoor air monitoring. Currently, there is a lack of sensitive, specific, affordable, and easy-to-use airborne pathogen monitoring technology and an overwhelming need for innovative approaches to address this challenge.
Annapolis, MD; November 30, 2023—Hung from a common utility pole, a fiber optic cable—the kind bringing high-speed internet to more and more American households—can be turned into a sensor to detect temperature changes, vibrations, and even sound, through an emerging technology called distributed fiber optic sensing.
Computer scientist Dr. Satish Puri is working on ways to organize and search for petabytes of geospatial data. He is developing algorithms that can use data for everything from geophysical trends to social issues. His work will eventually be incorporated into publicly available software for mapping and analytics.
Hospital germs and pathogens are not always transmitted directly from person to person. They can also spread via germ-contaminated surfaces and objects.
Cedars-Sinai investigators found no established link between the use of assisted reproductive technologies and potential problems in DNA methylation that might impact genetic expression or embryonic development.
Two teams that include scientists from U.S. Department of Energy’s (DOE) Argonne National Laboratory have been named finalists for the Association for Computing Machinery 2023 Gordon Bell Prize. Both teams conducted groundbreaking research with the use of high performance exascale computing tools, such as Frontier, a supercomputer at DOE’s Oak Ridge National Laboratory (ORNL).
This commentary considers the fields of extrasensory perception (ESP) research and cognitive neuroscience, discussing points of conflict and domains where they may be complementary.
LEXINGTON, Ky. (Oct. 12, 2023) — The Herculaneum scrolls are among the most iconic and inaccessible of the world’s vast collection of damaged manuscripts. Since being burned and carbonized by the catastrophic eruption of Mt. Vesuvius in 79 CE, they’ve been deemed “unreadable.” For more than 2,000 years, wisdom from the only library to survive from ancient times remained locked away.
