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 next head of Europe’s CERN physics laboratory said Thursday that he favored moving forward with plans for a giant particle collider far more powerful than the collider that discovered the famous “God particle”
Scientists disagree when the Thwaites or Doomsday Glacier will fully melt, but they are starting to weigh up large scale interventions.
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?

In order to figure out how something came from nothing, we first need to explore the different types of nothing.
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.
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.
Instead of the old-fashioned hammer and chisel, a 13-foot zinc alloy arm with a spinning, diamond-crusted finger is now used by some to cut marble. Robotor CEO Giacomo Massari says it’s ten times faster.
A fleet of marble-sculpting robots is carving out the future of the art world. It’s a move some artists see as cheating, but others are embracing the change.
Magnetotherapy has been receiving increased attention as an attractive strategy for modulating cell physiology directly at the site of injury, thereby providing the medical community with a safe and non-invasive therapy.

Mimicking how plants convert sunlight into energy has long been a dream for scientists aiming to create renewable energy solutions. Artificial photosynthesis is a process that seeks to replicate nature’s method, using sunlight to drive chemical reactions that generate clean energy. However, creating synthetic systems that work as organically as natural photosynthesis has been a significant challenge until now.
