Rhythms

Today Samsung has announced that the FDA has cleared the irregular heart rhythm notification for Galaxy Watch. This means that your Galaxy Watch device will eventually be able to tell you if it detects this event. Armed with the knowledge of an irregular heart rhythm detection, users can then activate the ECG function on their watch to gather a more accurate reading.The feature is designed to notify a user if it detects signs of atrial fibrillation, which is a type of arrhythmia. The reason for this feature addition is…

has revealed that the US Food and Drug Administration has approved the Health Monitor app's irregular heart rhythm notification (IHGN) feature for devices. The company says that, along with the wearable's electrocardiogram (ECG) capabilities, the feature can help to identify signs of atrial fibrillation (AFib), a type of arrhythmia. AFib is widely believed to be an alarm bell for potentially major cardiovascular issues that can lead to increased risk of stroke, heart failure and other complications. In some cases, those…

Circadian rhythm refers to the internal 24-hour cycle that regulates our physiological and behavioral processes, such as sleep-wake cycles, hormone production, and metabolism. It is influenced by external factors such as light, food intake, and temperature.A recent study conducted by a multidisciplinary team of researchers sheds light on the underlying mechanisms of circadian rhythms, providing new hope for managing jet lag, insomnia, and other sleep disorders.By utilizing advanced cryo-electron microscopy techniques, the…

A mainland Chinese attempt to cash in on Donnie Yen’s superior Hong Kong series about Bruce Lee’s eponymous sifu, this film’s quickstep fighting rhythms are bogged down by a laughable lack of effort on the narrative front. Budding martial arts master Ip Man, played here by former child star and Jet Li acolyte Miu Tse, arouses the ire of the arrogant British colonialist Mr Stark (played by Sergio de Ieso in a possible nod to Iron Man) after interrupting his human trafficking ring. That’s your lot story-wise; slogging…

Circadian rhythms have a unique characteristic in which the cycle period remains unchanged despite temperature fluctuations, even though the rate of many biochemical reactions is greatly affected by temperature changes. Researchers proposed a clever temperature compensation mechanism utilizing the Belousov-Zhabotinsky (BZ) oscillating reaction.Circadian rhythms are natural, internal oscillations that synchronize an organism’s behaviors and physiological processes with their environment. These rhythms normally have a…

The bare bones of Virginia Woolf’s 1927 novel sound a little unprepossessing: it begins shortly before the first world war with a young boy, James Ramsay, asking his parents if they can visit the lighthouse near the family’s summer house on the Isle of Skye, after which a discussion about the weather ensues. It goes on to chronicle a day in the life of the Ramsay parents, their eight children and their gaggle of house guests, who include a young artist, Lily Briscoe, who is painting Mrs Ramsay’s portrait; a prickly young…

Scientists have uncovered an important molecular link between lung tumor growth and disrupted circadian rhythms. Circadian rhythms, sometimes called the “biological clock,” is the cellular process that rules sleep-wake cycles.An important molecular link between lung tumor growth and disrupted circadian rhythms has been uncovered by scientists. The discovery is presented in a new paper co-authored by a Wilmot Cancer Institute investigator and led by the Scripps Research Institute in California.Circadian rhythms, sometimes…

"To see a world in a grain of sand", the opening sentence of the poem by William Blake, is an oft-used phrase that also captures some of what geologists do.We observe the composition of mineral grains, smaller than the width of a human hair.Then, we extrapolate the chemical processes they suggest to ponder the construction of our planet itself.Now, we've taken that minute attention to new heights, connecting tiny grains to Earth's place in the galactic environment.Looking out to the universeAt an even larger scale,…

The sounds of sloshing lava are music to a volcanologist's ears. The reverberating belches and burps can help reveal what's going on deep within a volcano's belly.Putting an ear to the Kīlauea volcano in Hawaii has allowed researchers to track the temperature of magma and the migration of volcanic gasses as they bubble to the surface.  The findings have revealed something unexpected about the volcano's famous 2018 eruption. "It's a new view into the dynamics of a really popular volcano," says earth scientist Leif…
