ROCHESTER, Minn. — A recent Mayo Clinic study examining the effects of daylight saving time (DST) on heart health suggests that the impact is likely minimal. In the nationwide study, researchers applied an advanced statistical model to look for any connections between DST and serious cardiovascular problems, including heart attacks and strokes. The study looked at 36,116,951 adults aged 18 and up across most U.S. states. (Arizona and Hawaii were excluded since these states do not observe DST.) Researchers focused on the week directly after the spring and fall DST transition, ...

A new tool could reduce costs for diagnosing infectious diseases. Biomedical researchers from The University of Texas at Austin have developed a new, less expensive way to detect nuclease digestion – one of the critical steps in many nucleic acid sensing applications, such as those used to identify COVID-19 and other infectious diseases.   A new study published in the journal Nature Nanotechnology shows that this low-cost tool, called Subak, is effective at telling when nucleic acid cleavage occurs, which happens when an enzyme called nuclease breaks down nucleic acids, such as DNA or RNA, into smaller fragments.  The traditional way of identifying nuclease ...

WEST LAFAYETTE, Ind. — Cooking on your gas stove can emit more nano-sized particles into the air than vehicles that run on gas or diesel, possibly increasing your risk of developing asthma or other respiratory illnesses, a new Purdue University study has found. “Combustion remains a source of air pollution across the world, both indoors and outdoors. We found that cooking on your gas stove produces large amounts of small nanoparticles that get into your respiratory system and deposit efficiently,” said Brandon Boor, an associate professor in Purdue’s Lyles School of Civil Engineering, who led this research. Based on these ...

Participants in a workshop organized by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) agree on the importance of mitigating degradation rates for the continuing rollout of clean technologies. Renewable energy is forecast to play an expanded role in meeting future needs, with terawatts of electricity expected to be generated from wind and solar, so the performance of the technologies involved is becoming increasingly important. Any technology degrades over time, so researchers are looking at ways to curb this issue. Mitigating degradation will become a factor ...

Youth mental health in urban environments is significantly better when more nature is incorporated into city design.  A new study from University of Waterloo researchers suggests that forest bathing, the simple method of being calm and quiet amongst the trees, observing nature around you while breathing deeply, can help youth de-stress and boost health and well-being. The study was the first ever to collect on-site, real-time survey data from adolescents about their emotional responses to various urban environments like a transit hub, residential ...

The National Science Foundation awarded Grant Shields, assistant professor of psychological science at the U of A, with a prestigious Faculty Early Career Development award to support his research on the cognitive mechanisms and processes underlying inhibitory control under stress. Inhibitory control is the means by which automatic urges, emotions and behaviors, like wanting to tell your boss what you really think about being asked to work Saturday, are controlled to produce (ideally) better outcomes (yes, you’ll work Saturday because the need for a paycheck outweighs the desire ...

CAMBRIDGE, MA -- Hundreds of robots zip back and forth across the floor of a colossal robotic warehouse, grabbing items and delivering them to human workers for packing and shipping. Such warehouses are increasingly becoming part of the supply chain in many industries, from e-commerce to automotive production. However, getting 800 robots to and from their destinations efficiently while keeping them from crashing into each other is no easy task. It is such a complex problem that even the best path-finding algorithms struggle to keep up with the breakneck pace of e-commerce or manufacturing.  In a sense, ...

Dartmouth researchers report they have developed the first smartphone application that uses artificial intelligence paired with facial-image processing software to reliably detect the onset of depression before the user even knows something is wrong. Called MoodCapture, the app uses a phone's front camera to capture a person's facial expressions and surroundings during regular use, then evaluates the images for clinical cues associated with depression. In a study of 177 people diagnosed with major depressive disorder, the app correctly identified early symptoms of depression with 75% accuracy. These results suggest the technology could be publicly ...

People living in ancient Eastern Arabia appear to have developed resistance to malaria following the appearance of agriculture in the region around five thousand years ago, a new study reveals. DNA analysis of the remains of four individuals from Tylos-period Bahrain (300 BCE to 600 CE) - the first ancient genomes from Eastern Arabia - revealed the malaria-protective G6PD Mediterranean mutation in three samples. The discovery of the G6PD Mediterranean mutation in ancient Bahrainis suggests that many people in ...

PITTSBURGH, Feb. 27, 2024 – Bariatric surgery is more effective than medical and lifestyle modifications for achieving long-term Type 2 diabetes control and remission, according to new research led by a University of Pittsburgh School of Medicine surgeon-scientist and published today in JAMA. In the largest and longest randomized follow-up study to date, the researchers also found that bariatric surgery improved cholesterol and triglyceride levels more effectively than did medical and lifestyle modifications. Since diabetes and cholesterol are important risk factors for heart disease, the management of both may contribute to fewer heart attacks, strokes and other complications. “This ...

About The Study: The findings of this study of 173,000 adult patients who died with cancer suggest that the COVID-19 pandemic was associated with amplified socioeconomic disparities in death at home and specialized palliative care delivery at the end of life. Future research should focus on the mechanisms of these disparities and on developing interventions to ensure equitable and consistent specialized palliative care access.  Authors: Camilla Zimmermann, M.D., M.P.H., Ph.D., of the Princess Margaret Cancer Centre in Toronto, is the corresponding ...

About The Study: This study of routine screening with fecal occult blood testing found a 14% decrease in colorectal cancer mortality associated with screening. The true association of screening with reduced mortality is expected to be higher due to some coexistence of testing in the control group and colorectal cancer deaths diagnosed more than two years after screening.  Authors: Johannes Blom, M.D., Ph.D., of the Karolinska Institutet in Stockholm, is the corresponding author.  To access the embargoed study: Visit our For The ...

The sunlight received by Earth is a mixed bag of wavelengths ranging from ultraviolet to visible to infrared. Each wavelength carries inherent energy that, if effectively harnessed, holds great potential to facilitate solar hydrogen production and diminish reliance on non-renewable energy sources. Nonetheless, existing solar hydrogen production technologies face limitations in absorbing light across this broad spectrum, particularly failing to harness the potential of NIR light energy that reaches Earth. Recent research has identified that both Au and Cu7S4 nanostructures exhibit a distinctive optical characteristic known as localized surface plasmon resonance (LSPR) (Fig.1). ...

There’s a lot of research about moving away from carbon as an energy source, but what if instead the carbon that is being used is applied to its full capacity?   The importance of carbon as an energy source is not to be downplayed. Unfortunately, the reliance on these carbon-based materials has proven to be disastrous for the environment, especially in the quantities they are consumed on a global basis. Therefore, alternative means have to be researched. Superstructure carbons (SCC) are a possible way to use carbons in a more efficient and “green” way that can exceed the current performance and longevity ...
