A new study of molecular interactions central to the functioning of biological clocks explains how certain mutations can shorten clock timing, making some people extreme "morning larks" because their internal clocks operate on a 20-hour cycle instead of being synchronized with the 24-hour cycle of day and night.
The study, published February 11 in eLife, shows that the same molecular switch mechanism affected by these mutations is at work in animals ranging from fruit flies to people.
The scent of a romantic partner can improve sleep, suggests new psychology research from the University of British Columbia.
The researchers found that study participants who were exposed to their partner's scent overnight experienced better sleep quality, even though their partner was not physically present.
Researchers at the University of Technology Sydney (UTS) have developed a cost-effective and practical method to protect pipelines and keep them operating during significant fault rupture incidents and large ground movements.
Australia's pipeline length of 50,000 km has a critical role in transporting water, gas and oil products, and transferring sewage to treatment plants.
Researchers led by Tokyo Medical and Dental University find that neuronal necrosis occurs much earlier in Alzheimer's disease progression than originally thought, and uncover a novel target for future treatment strategies
Evidence of intrauterine vertical transmission was assessed by testing for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, formerly the 2019 novel coronavirus or 2019-nCoV) in amniotic fluid, cord blood, and neonatal throat swab samples from six pregnancies. All samples were negative.
Study also evaluated clinical characteristics of the 2019 novel coronavirus disease (COVID-19) infection in nine pregnant women.
MIAMI--Toxic and invisible oil spread well beyond the known satellite footprint of the Deepwater Horizon oil spill, according to a new study led by scientists at the University of Miami (UM) Rosenstiel school of Marine and Atmospheric Science. These new findings have important implications for environmental health during future oil spills.
INFORMS Journal Manufacturing & Service Operations Management Study Key Takeaways:
An increase in the number of stores directly decreases consumer waste due to improved access to groceries.
Too many stores could increase store waste due to distribution of inventory and price competition.
The optimal solution to reduce food waste is to increase the number of stores in a given area, but not too much. The perfect balance will ensure a drop in food waste.
LAS VEGAS - February 11, 2020 - Popular diets low in carbs and high in fat and protein might be good for the waistline, but a new UNLV study shows that just the opposite may help to alleviate the hospital-acquired infection Clostridioides difficile.
With more than a quarter of U.S. adults now having tattoos -- and nearly half of millennials sporting them -- only a handful of studies have focused on religious tattoos. But a new study by researchers at Baylor University and Texas Tech University analyzes faith-centered tattoos and is the first to use visual images of them.
The study, published in the journal Visual Studies, analyzed 752 photos of tattoos taken at a Christian university in the United States and found that nearly 20% of those were overtly religious in content.
AURORA, Colo. (Feb. 12, 2020) - A major multi-center investigation of children with cystic fibrosis has identified a test that allows earlier identification of those at risk for cystic fibrosis liver disease.
The study, which includes 11 clinical sites in North America, was led by Michael Narkewicz, MD, professor of pediatrics from the University of Colorado School of Medicine and Children's Hospital Colorado. The findings of the study are published today ahead of print in The Journal of Pediatrics.
As machine learning continues to surpass human performance in a growing number of tasks, scientists at Skoltech have applied deep learning to reconstruct quantum properties of optical systems.
Through a collaboration between the quantum optics research laboratories at Moscow State University, led by Sergey Kulik, and members of Skoltech's Deep Quantum Laboratory of CPQM, led by Jacob Biamonte, the scientists have successfully applied machine learning to the state reconstruction problem.
Accurately predicting biodiversity loss from climate change requires a detailed understanding of what aspects of climate change cause extinctions, and what mechanisms may allow species to survive.
U.S. Army convoys could be made safer for soldiers by implementing autonomous vehicle technology to reduce the number of service members needed to operate the vehicles, according to a new study from the RAND Corporation.
"The Army is interested in autonomous technology because if they can reduce the number of soldiers needed to run a convoy, they can keep soldiers safe," said Shawn McKay, lead author of the study and a senior engineer with RAND, a nonprofit research organization.
Economists and business leaders agree that innovation is a major force behind economic growth, but many disagree on what is the best way to encourage workers to produce the "think-outside-of-the-box" ideas that create newer and better products and services. New research from the University of California San Diego indicates that competitive "winner-takes-all" pay structures are most effective in getting the creative juices flowing that help fuel economic growth.
Researchers at the National Institute of Standards and Technology (NIST) have found a way to link measurements made by a device integral to microchip fabrication and other industries directly to the recently redefined International System of Units (SI, the modern metric system). That traceability can greatly increase users' confidence in their measurements because the SI is now based entirely on fundamental constants of nature.
