Fu et al. use Ig-humanized mice expressing the germline CR3022 heavy chain to reveal how somatic hypermutation rapidly adapts this antibody class for broad sarbecovirus recognition. Sequential immunization drives CR3022-like maturation, while structural analyses show that increased affinity and breadth arise from subtle polar and electrostatic refinements.
Researchers have demonstrated a superconducting quantum circuit that simulates tunneling in chemical reactions, revealing unexpected quantum effects in state transitions.
The work enables controlled study of quantum dynamics in chemistry-like energy landscapes and highlights superconducting circuits as powerful tools for exploring chemical processes.

A continuously driven Kerr parametric oscillator simulates a dissipative quantum system with applications to reactions in quantum chemistry.
The idea that everything that exists can be built from the bottom up has long held sway among physicists. Now, a new kind of science is under construction that centres conscious experience – and might unravel the universe’s biggest mysteries.
I talk about the science of Project Hail Mary and why it makes the story feel so grounded, exciting, and believable.
From microbes in space to the real challenges of long-duration space travel, this section looks at how the movie uses science as more than just background decoration. It also gets into why stories like this feel so refreshing right now, because they make curiosity, intelligence, and problem-solving feel dramatic again.
This is a conversation about the real science behind Project Hail Mary, what NASA’s work has to do with the movie, and why science fiction can still inspire wonder.

Today thanks to progress in medicine and science our generation may live longer than any previous one. There wasn’t better time to start taking care of our health than today. Future is amazing. To participate in it we must to take care of our health today.
The brain changes associated with Alzheimer’s usually lead to a severe loss of memory and cognitive abilities, but not always.
Now, a new study led by a team at the University of California, San Diego (UCSD) helps explain why.
Based on postmortem brain research, around 20 to 30 percent of older adults are thought to have asymptomatic Alzheimer’s disease (ASYMAD). Their brains have the characteristic buildup of misfolded amyloid-beta and tau proteins, but they show no detrimental mental effects.
Humanity may not colonize planets—we may build our own worlds. Explore how rotating space habitats could spread across the Solar System and beyond, forming a vast diaspora of artificial worlds that reshape civilization and interstellar expansion.
