Sleep Number presents new data from its 360® Smart Beds at SLEEP 2021 Annual Meeting

Deaths from suicide are rising in the United States. These rising trends are especially alarming because global trends in suicide are on a downward trajectory. Moreover, in the U.S., the major mode of suicide among young Americans is by firearms. Researchers from Florida Atlantic University's Schmidt College of Medicine and collaborators explored trends in suicide by firearms in young white and black Americans (ages 5 to 24 years) from 1999 to 2018. Results, published in the journal Annals of Public Health and Research, showed that between 2008 and 2018, rates of suicide by firearms quadrupled in young Americans ages 5 to 14 ...

Chemical rings of carbon and hydrogen atoms curve to form relatively stable structures capable of conducting electricity and more -- but how do these curved systems change when new components are introduced? Researchers based in Japan found that, with just a few sub-atomic additions, the properties can pivot to vary system states and behaviors, as demonstrated through a new synthesized chemical compound. The results were published on April 26 in the Journal of the American Chemical Society. "In the past decade, open-shell molecules have attracted considerable attention not only in the field of reactive intermediates, but also in materials science," said paper author Manabu Abe, ...

In the first three quarters of 2020, the COVID-19 pandemic caused a 30% fall in electronic and electrical equipment sales in low- and middle-income countries but only a 5% decline in high-income countries, highlighting and intensifying the digital divide between north and south, according to a new UN report. Worldwide, sales of heavy electric appliances like refrigerators, washing machines and ovens fell the hardest -- 6-8% -- while small IT and telecommunications equipment decreased by only 1.4%. Within the latter category, sales of laptops, cell phones and gaming equipment rose in high-income countries and on a global basis, but fell in low- and middle-income ...

To focus on what's new, we disregard what's not. A new study by researchers at MIT's Picower Institute for Learning and Memory substantially advances understanding of how a mammalian brain enables this "visual recognition memory." Dismissing the things in a scene that have proven to be of no consequence is an essential function because it allows animals and people to quickly recognize the new things that need to be assessed, said Mark Bear, Picower Professor in the Department of Brain and Cognitive Sciences and senior author of the study in the Journal of Neuroscience. "Everyone's appropriate behavioral response to an unexpected stimulus is to devote attentional resources to that," Bear said. "Maybe it means danger. Maybe it means food. But if you learn that this once-novel ...

For the first time, Australian scientists have confirmed a link between the role of regular fish oil to break down the ability of 'superbugs' to become resistant to antibiotics. The discovery, led by Flinders University and just published in international journal mBio, found that the antimicrobial powers of fish oil fatty acids could prove a simple and safe dietary supplement for people to take with antibiotics to make their fight against infection more effective. "Importantly, our studies indicate that a major antibiotic resistance mechanism in cells can be negatively impacted by the uptake of omega-3 dietary lipids," says microbiologist Dr Bart Eijkelkamp, who leads the Bacterial Host Adaptation Research Lab at ...

As many older adults get back to normal life across the United States thanks to high rates of vaccination and lower COVID-19 activity, a new poll suggests many should watch their alcohol intake. In all, 23% of adults over 50 who drink alcohol reported that they routinely had three or more drinks in one sitting, according to END ...

DALLAS, June 9, 2021 -- Many adults with a history of cardiovascular disease (CVD) continue to smoke cigarettes and/or use other tobacco products, despite knowing it increases their risk of having another cardiovascular event, according to new research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association. To understand how many adults with CVD continue to use tobacco products, investigators reviewed survey responses from the large, national Population Assessment of Tobacco and Health Study (PATH) to compare tobacco use rates over time. The participants of the current study included 2,615 adults (ages 18 or older) with a self-reported history of heart attack, heart failure, stroke or other heart disease, ...

The field of ultrafast nonlinear photonics has now become the focus of numerous studies, as it enables a host of applications in advanced on-chip spectroscopy and information processing. The latter in particular requires a strongly intensity-dependent optical refractive index that can modulate optical pulses faster than even picosecond timescales and on sub-millimeter scales suitable for integrated photonics. Despite the tremendous progress made in this field, there is currently no platform providing such features for the ultraviolet (UV) spectral range, which is where broadband spectra generated by nonlinear modulation can be used for new on-chip ultrafast chemical and biochemical spectroscopy devices. Now, an ...

An international group of collaborators, including scientists from NASA's Jet Propulsion Laboratory and The University of New Mexico, have discovered a new, temperate sub-Neptune sized exoplanet with a 24-day orbital period orbiting a nearby M dwarf star. The recent discovery offers exciting research opportunities thanks to the planet's substantial atmosphere, small star, and how fast the system is moving away from the Earth. The research, titled TOI-1231 b: A Temperate, Neptune-Sized Planet Transiting the Nearby M3 Dwarf NLTT 24399, will be published in a future issue of The Astronomical Journal. The exoplanet, TOI-1231 b, was detected ...

The presence and accumulation of the antioxidant pigment anthocyanin dictates fruit hue in plums, and the synthesis of this compound is known to be regulated by the MYB10 genes. Now, researchers from the Centre for Research in Agricultural Genomics (CRAG) and the Institute of Agrifood Research and Technology (IRTA) have found the gene that determines Japanese plum skin colour. In a END ...
