The results will also allow researchers to explore more deeply how living in conflict with our individual internal time can lead to poorer health and may point to future individualized intervention strategies.” These small differences may have potentially significant effects on the ability of our body clocks to keep time effectively, potentially altering risk of both disease and mental health disorders.”Ĭo-lead author Jacqueline Lane of the MGH Department of Anesthesia added, “By understanding the genetics of sleep and activity timing in the general population, we also gain insights into potential avenues of therapy for individuals with more extreme conditions, such as those with advanced or delayed circadian rhythm disorders.”Ĭo-senior author Richa Saxena, MGH Anaesthesia and an associate professor of anaesthesia at Harvard Medical School, said, “This study highlights the power of teamwork and large-scale human genetics to reveal new aspects of the biology and health implications of our body clocks. Our work indicates that part of the reason why some people are up with the lark while others are night owls is because of differences in both the way our brains react to external light signals and the normal functioning of our internal clocks. However, we still know very little about whether or not your body clock influences your risk of disease. Jones of the University of Exeter Medical School said, “The discovery of this fundamental body-clock mechanism in the brain recently won the Nobel Prize for medicine in 2017. Our body clock affects a wide range of molecular processes, including hormone levels and core body temperature, as well as our waking and sleeping patterns. ![]() The retinal connection may help explain how the brain detects light to “reset” the body clock each day and align with the 24-hour cycle. Our body clocks are influenced by genes and lifestyle factors including diet, exposure to artificial light, and our jobs and activities. The body clock cycle is slightly longer than the 24-hour daily cycle. The genomic regions identified include those central to our body clocks, also referred to as circadian rhythms, as well as genes expressed in the brain and in retinal tissue. The researchers found that the genetic areas influenced sleep timing but not the quality or duration of sleep. This information showed that the genetic variants the researchers identified could shift a person’s natural waking time by up to 25 minutes - changing some people’s waking time from 8 a.m. The researchers confirmed their results using information from wrist-worn activity trackers used by more than 85,000 individuals in the U.K. ![]() All participants were asked if they were “morning people” or “evening people,” and their genomes were analyzed to look at genes they had in common that may influence their sleep patterns. The work was conducted in 250,000 U.S.-based research participants in 23andMe, a company that provides private genomic analyses, and 450,000 people in the U.K. The large number of people in our study means we have provided the strongest evidence to date that ‘night owls’ are at higher risk of mental health problems, such as schizophrenia and lower mental well-being, although further studies are needed to fully understand this link.” Michael Weedon of the University of Exeter Medical School, who led the research, said, “This study highlights a large number of genes which can be studied in more detail to work out how different people can have different body clocks. It also increased the number of areas of the genome known to influence whether someone is an early riser from 24 to 351. ![]() It highlighted the key role of the retina in helping the body keep time. The study was conducted by an international collaboration, led by the University of Exeter and Harvard-affiliated Massachusetts General Hospital (MGH) and funded primarily by the Medical Research Council of the U.K. However, despite much previous speculation, the results did not reveal any strong links to diseases such as diabetes or obesity. The study, published in Nature Communications, suggests that being genetically programmed to rise early may lead to greater well-being and a lower risk of schizophrenia and depression. EXETER, U.K./BOSTON - A large-scale genomic analysis has revealed some of the inner workings of the body clock, shedding new light on how it links to mental health and disease. ![]()

![]() The 6-inch HD E Ink Carta 1200 screen makes it lightweight and easy to carry. This is the first Kobo e-reader made from recycled and ocean-bound plastics. The 300ppi E Ink Carta 1200 screen is the same new panel as on the Elipsa, giving a comfortable reading experience. Although heavier than its predecessors, the Libra 2 is still comfortable to hold, thanks to the dedicated grip area. Libra 2 has built-in page-turn buttons and provides space for gripping the device, thus giving a more book-like handling experience. Thanks to its waterproof casing, you can take your e-reader in the bath or pool. The Bluetooth support is a much-welcome change, which allows you to listen to audiobooks on the e-reader. The 7-inch Kobo Libra 2 looks like Libra H2O with key differences in battery capacity, Bluetooth support, and USB-C. So, Kobo Sage is the best e-reader for all situations. ![]() It has many features that are missing on Elipsa, like Bluetooth, waterproof casing, and physical buttons. It’s more compact and portable than Elipsa. In fact, Sage combines the pros of the Elipsa and the Libra 2. But this medium-sized e-reader with an 8-inch screen is best for reading at home and on the go. Kobo Sage has many features in common with Elipsa 2E. It comes packaged with Kobo Stylus 2, which lets you write or annotate directly onto books. Kobo Elipsa 2E and Kindle Scribe have many things in common, but the software experience of the former feels better.īut this e-reader may not be for audiobook fans because its audiobook selection is more limited than Amazon’s. The 32GB of non-expandable storage gives you plenty of room for eBooks, Kobo audiobooks, and every note. Fast and responsive, Kobo Elipsa 2E is an excellent e-reader for both reading and note-taking. It’s great for reading in most situations except when traveling due to the bigger screen. The 10.3in E Ink display, paired with high 1404X1872 resolution and adjustable front light, provides excellent clarity and contrast. If you’re looking for a Kobo e-reader with the largest screen, you need the latest version Elipsa 2E. In this blog, we’re going to review the top 5 Kobo e-readers you can consider buying. I then download unlimited books from the library for a fixed monthly price.Are you looking to buy a Kobo e-reader? Great! You’ve selected a great brand. I find this very useful, especially if I take out a Kobo Plus subscription. But when I buy a new book in Kobo's online library, I put it on my e-reader with 1 push of a button via WiFi. I easily transfer books that I already own to my e-reader via the supplied cable. I connect headphones via bluetooth and listen to my favorite books hands-free. Another nice feature is that I also listen to audiobooks. This works less pleasantly than buttons in the housing of the e-reader. Now I flip through a book by tapping the screen. What I do miss with this e-reader are physical buttons. This ensures a peaceful reading experience. Then the background of the screen is black and the letters are white. I fall asleep quickly at night after reading in bed. ![]() ComfortLight Pro gives the screen a warmer hue when it gets dark. The e-reader has useful functions that are pleasant to my eyes. A note: when I read at home I would find a larger screen more comfortable. This is how I eat my breakfast and in the meantime I read a biography. Thanks to the built-in stand, I also put it upright. I use the Kobo SleepCover to protect the e-reader against damage. I store thousands of books on the memory. In addition, I am not worried about insufficient reading material. Much more convenient than carrying around a thick paper book. This works especially well for me when I read on the bus and train. I put the e-reader in my bag, without it taking up much space. This e-reader is certainly suitable for that. I like to read on public transport on my way to work.

Price was remember by Bishop Charles Blake of West Angeles Church of God in Christ. While at the Baptist church, Price would preach while working other jobs such as driving for Coca-Cola. He said his spiritual realization began when he accompanied Betty to a Christian tent revival service. Price, met his wife, Betty, in the 1950s when they both attended Dorsey High School.
