Successful aging starts with a good night’s sleep, study suggests

Posted by in category: life extension

Researchers at Wenzhou Medical University in China have discovered that changes in sleep patterns as we age are associated with lower odds of successful aging.

New medical procedure for treating irregular heart rhythm

Posted by in category: biotech/medical

The technology is designed to treat the condition atrial fibrillation, or irregular heart rhythm. This is in a way that carries a lower risk of complications and shorter anaesthesia time (when compared to traditional treatment).

The new technology took eighteen years to develop. In recent months, pulsed field ablation has been approved by the U.S. Food and Drug Administration (FDA) and the acceptance marks a milestone in heart treatment.

The process involves the use of microsecond-scale, high-voltage electrical fields to cause irreversible electroporation and destabilization of cell membranes, according to the New England Journal of Medicine.

Unveiling the secrets of aging: Scientists discover dual role of immunoglobulins

Posted by in category: life extension

A team of scientists from the Chinese Academy of Sciences (CAS) and BGI Research has uncovered the intricate mechanisms by which immunoglobulins influence the aging process, a finding that might reshape our understanding of aging.

The Big Bang Is Beyond Doubt. An Expert Reveals Why

Posted by in category: cosmology

How did everything begin? It’s a question that humans have pondered for thousands of years. Over the last century or so, science has homed in on an answer: the Big Bang.

This describes how the Universe was born in a cataclysmic explosion almost 14 billion years ago. In a tiny fraction of a second, the observable universe grew by the equivalent of a bacterium expanding to the size of the Milky Way. The early universe was extraordinarily hot and extremely dense. But how do we know this happened?

Why does our universe have something instead of nothing?

Posted by in category: futurism

In order to figure out how something came from nothing, we first need to explore the different types of nothing.

Scientists Caught Sperm Defying One of The Laws of Physics

Posted by in categories: biological, mathematics, physics, sex

With their slender tails, human sperm propel themselves through viscous fluids, seemingly in defiance of Newton’s third law of motion, according to a recent study that characterizes the motion of these sex cells and single-celled algae.

Kenta Ishimoto, a mathematical scientist at Kyoto University, and colleagues investigated these non-reciprocal interactions in sperm and other microscopic biological swimmers, to figure out how they slither through substances that should, in theory, resist their movement.

When Newton conceived his now-famed laws of motion in 1686, he sought to explain the relationship between a physical object and the forces acting upon it with a few neat principles that, it turns out, don’t necessarily apply to microscopic cells wriggling through sticky fluids.

We Finally Know Where Most Meteorites on Earth Actually Came From

Posted by in categories: materials, space

Until now, only a small fraction of meteorites that land on Earth had been firmly linked back to their parent body out in space – but a set of new studies has just given us compelling origin stories for more than 90 percent of meteorites today.

Past analyses of meteorites striking our planet today suggest some kind of shared origin; they’re made from very similar materials and have been baked by cosmic radiation for a suspiciously short amount of time, hinting at a relatively recent break-up from shared parent bodies.

The teams behind three new published papers used a combination of super-detailed telescope observations and computer modeling simulations to compare asteroids out in space with meteorites recovered on Earth, matching up rock types and orbital paths between the two.
