New research has found that during a six-month stay on the International Space Station, astronauts were destroying 3 million red blood cells every second. That's 54 percent more than the 2 million our bodies destroy and replace every second on Earth.

Scientists have developed first-of-a-kind "Xenobots" from frog cells with the ability to self-replicate, a technology that could find use in regenerative medicine and and reveals a type of biological reproduction never before observed in science.

Scientists have discovered a new type of cell in the heart. The cells, now named nexus glia, seem to help regulate heart rate and rhythm, and the team says they may unlock new understandings of some heart defects and diseases.

Stem cell transplants to treat blood cancers can be a risky process. In a new study in mice, researchers found a way to make the process safer by targeting a patient’s faulty stem cells more precisely, removing the need for radiation or chemotherapy.

The microscopic world is important to understand, but tricky to study in detail. Researchers at EPFL have now developed a new microscopy technique that combines two existing ones, allowing scientists to build high-definition 3D images of cells inside and out.

Aging affects everybody, so it’s easy to understand why so much scientific attention is focused on studying it. Scientists in Canada now claim to have found that telomeres play a different role in cellular aging than previously thought.

Researchers in Australia have tapped into cutting-edge materials science to produce the world's thinnest X-ray detector, which is highly suited to the imaging of wet proteins and living cells, and has the potential to do so on in real time.

New research has discovered a distinct circadian mechanism within heart cells that influences how cardiac activity shifts across 24-hour periods. The findings offer clues to why shift workers are at higher risk of heart problems.

How life first emerged from non-living matter is one of the most enduring mysteries of science. In a new study, scientists have created self-replicating protocells in the lab, which could represent the “missing link” between chemistry and biology.

Paleontologists have isolated cartilage cells from an exceptionally well-preserved dinosaur fossil. They still contain traces of biomolecules, and the scientists were even able to tell which stage of the natural cycle specific cells were in at death.

It may sound like the start of a Frankenstein story, but scientists from New York University (NYU) and the University of Chicago have developed artificial cells made of non-biological matter that mimic the basic functions of living ones.

CAR T cell immunotherapy is a promising treatment for cancer, but it can trigger dangerous side effects. A new study precisely targets cancer by engineering CAR T cells to activate at higher temperatures, then heating tumors with ultrasound.
