Good sleep habits important for overweight adults, OHSU study suggests

Good sleep habits important for overweight adults, OHSU study suggests
2024-08-23
(Press-News.org) New research from Oregon Health & Science University reveals negative health consequences for people who are overweight and ignore their body’s signals to sleep at night, with specific differences between men and women.

The study published this week in The Journal of Clinical Endocrinology & Metabolism.

“This study builds support for the importance of good sleep habits,” said lead author Brooke Shafer, Ph.D., a postdoctoral researcher in the Sleep, Chronobiology and Health Laboratory in the OHSU School of Nursing.  “Sleep practices, like going to bed when you’re tired or setting aside your screen at night, can help to promote good overall health.”

The study recruited 30 people, split evenly between men and women. All had a body mass index above 25, which put them into an overweight or obese category.

“Obesity and cardiometabolic disease are growing public health concerns,” Shafer said. “Our research shows that disruptions in the body’s internal biological clock could contribute to negative health consequences for people who may already be vulnerable due to weight.”

Generally healthy participants contributed a saliva sample every 30 minutes until late in the night at a sleep lab on OHSU’s Marquam Hill campus to determine the time at which their body started naturally producing the hormone melatonin. Melatonin is generally understood to begin the process of falling asleep, and its onset varies with an individual’s internal biological clock.

Participants then went home and logged their sleep habits over the following seven days.

Researchers assessed the time difference between melatonin onset and average sleep timing for each participant, categorizing them into two groups: those who had a narrow window, with a short time duration between melatonin onset and sleep, and those with a wide window, with a longer duration between melatonin onset and sleep. A narrow window suggests someone who is staying awake too late for their internal body clock and is generally associated with poorer health outcomes.

The new study confirmed a variety of potentially harmful health measures in the group that went to sleep closer to melatonin onset.

It also found key differences between men and women. Men in this group had higher levels of belly fat and fatty triglycerides in the blood, and higher overall metabolic syndrome risk scores than the men who slept better. Women in this group had higher overall body fat percentage, glucose and resting heart rates.

“It was really somewhat surprising to see these differences present themselves in a sex-dependent manner,” said senior author Andrew McHill, Ph.D., assistant professor in the OHSU School of Nursing, the School of Medicine and the Oregon Institute of Occupational Health Sciences at OHSU. “It’s not one size fits all, as we sometimes think in academic medicine.”

The next phase of research will determine sex-specific differences in groups that experience more severe changes in sleep patterns, such as workers pulling overnight shifts.

“We want to figure out possible interventions that keep this vital core group of the workforce healthy,” Shafer said.

Unconventional interface superconductor could benefit quantum computing

2024-08-23
RIVERSIDE, Calif. -- A multi-institutional team of scientists in the United States, led by physicist Peng Wei at the University of California, Riverside, has developed a new superconductor material that could potentially be used in quantum computing and be a candidate “topological superconductor.”  Topology is the mathematics of shape. A topological superconductor uses a delocalized state of an electron or hole (a hole behaves like an electron with positive charge) to carry quantum information and process data in a robust manner. The researchers report today in Science Advances that they combined trigonal tellurium ...

NASA’s DART impact permanently changed the shape and orbit of asteroid moon

NASA’s DART impact permanently changed the shape and orbit of asteroid moon
2024-08-23
When NASA’s Double Asteroid Redirection Test (DART) spacecraft collided with an asteroid moon called Dimorphos in 2022, the moon was significantly deformed—creating a large crater and reshaping it so dramatically that the moon derailed from its original evolutionary progression—according to a new study. The study’s researchers believe that Dimorphos may start to “tumble” chaotically in its attempts to move back into gravitational equilibrium with its parent asteroid named Didymos. “For ...

Multiple sclerosis appears to protect against Alzheimer’s disease

2024-08-23
People with multiple sclerosis (MS) are far less likely than those without the condition to have the molecular hallmarks of Alzheimer’s disease, according to new research from Washington University School of Medicine in St. Louis. The discovery suggests a new avenue of research through which to seek Alzheimer’s treatments, said Matthew Brier, MD PhD, an assistant professor of neurology and of radiology and the study’s first author. “Our findings imply that some component of the biology of multiple sclerosis, ...

Scientists propose guidelines for solar geoengineering research

2024-08-23
Scientists for several years have studied the theoretical effectiveness of injecting sulfur dioxide into the stratosphere to reflect heat from the Sun and offset Earth’s warming temperatures. But they also want to ensure that the solar geoengineering approaches being studied are evaluated for their technical feasibility, as well as their cooling potential and possible ecological and societal side effects. To guide future work, an international team of scientists led by the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR) has published a paper with specific recommendations for evaluating proposals to inject sulfur dioxide, which is known as stratospheric ...

Toward a code-breaking quantum computer

2024-08-23
CAMBRIDGE, MA — The most recent email you sent was likely encrypted using a tried-and-true method that relies on the idea that even the fastest computer would be unable to efficiently break a gigantic number into factors. Quantum computers, on the other hand, promise to rapidly crack complex cryptographic systems that a classical computer might never be able to unravel. This promise is based on a quantum factoring algorithm proposed in 1994 by Peter Shor, who is now a professor at MIT. But while researchers have taken great strides in the last 30 years, scientists ...
