Scientists Reveal How Much Sleep You Need For 'Successful Aging'
2 days ago · Chances of successful aging was significantly greater among the long stable and normal stable groups (17.1 percent and 18.1 percent respectively) compared to those in the decreasing (9.9 percent), increasing (10.6 percent), and short stable (8.8 percent) groups.. Successful aging by sleep pattern. (Tian et al., BMC Public Health, 2024) "Relative to participants with the normal stable sleep ...
We Finally Know What Switched on The Lights at The Dawn of Time
We finally know what brought light to the dark and formless void of the early Universe. According to data from the Hubble and James Webb Space Telescopes, the origins of the free-flying photons in the early cosmic dawn were small dwarf galaxies that flared to life, clearing the fog of murky hydrogen that filled intergalactic space.
There's a Critical Thing We Can Do to Keep Alzheimer's Symptoms …
2 days ago · The study echoes previous research which has found a build-up of amyloid-beta proteins in the brains of people with disrupted sleep. But poor sleep is both a risk factor for and a symptom of Alzheimer's disease, making it tricky to tease apart cause and effect. Likewise, clumpy amyloid-beta proteins might only be a sign of Alzheimer's disease ...
Scientists Figured Out How And When Our Sun Will Die, And It's …
Sep 5, 2021 · An international team of astronomers flipped it again in 2018 and found that a planetary nebula is indeed the most likely solar corpse. The Sun is about 4.6 billion years old – gauged on the age of other objects in the Solar System that formed around the same time. Based on observations of other stars, astronomers predict it will reach the ...
Fusion Breakthrough: 6 Minutes of Plasma Sets New Reactor Record
May 7, 2024 · The ultimate goal is to sustain a super-hot plasma for many hours, but 6 minutes is a new world record for a device like WEST. Other nuclear reactors similar to WEST have created hotter plasmas, but they haven't lasted as long. WEST is what's called a tokamak. It's a donut-shaped fusion reactor the size of an 8-by-8-foot room with 8-foot-tall ...
New Discovery Paves The Way to Generating Energy From Body …
4 days ago · The thermoelectric effect is a phenomenon that can help turn heat into electricity. This works by having a temperature difference produce an electric potential, as electrons flow from the hot side to the cool side, generating usable electrical energy. Conventional thermoelectric materials, however, are often made from cadmium, lead, or mercury.
Scientists Slowed Down Light by 10,000 Times in an Experiment
Based on the results obtained by the researchers, light can be slowed down by more than 10,000 times in this system. At the same time, the light loss is reduced by more than five times compared with other comparable methods. Key to the new approach is the way that the tiniest building blocks of the metasurface – known as meta-atoms – are ...
The 6th Mass Extinction Really Has Begun, Scientists Warn in …
Jan 18, 2022 · For years, scientists have rung the alarm bell, warning that grave declines in animal biodiversity around the globe herald the onset of what will be Earth's sixth mass extinction. Despite the looming weight of evidence to suggest this grim phenomenon is unfolding all around us, not everybody agrees. "Drastically increased rates of species ...
