Stanford scientists have discovered a new type of immune cell that kills surrounding cells via explosion—a cellular detonation so fast and complete that the cell vanishes within minutes, leaving no trace behind. This discovery ...
The Mexican axolotl (Ambystoma mexicanum) is famous because adults look like overgrown babies, or tadpoles, retaining juvenile features as adults and capable of remarkable regeneration of lost limbs or tails. New studies ...
For centuries, the inability to regrow lost body parts has been considered a defining limitation of humans and other mammals. While animals like salamanders can regenerate entire limbs, humans are left with scar tissue. But ...
Investigating a common gene in three very different species—salamanders, mice and zebrafish—scientists have discovered the potential for a novel gene therapy aimed at eventually regrowing limbs in humans, according to new ...
New research by an interdisciplinary team in Lithuania has revealed a promising and unconventional approach to cartilage regeneration. Using extracellular vesicles derived from menstrual blood stromal cells, the researchers ...
Experiments conducted in Brazil using laboratory rats have shown that graphene-based structures can act as a powerful ally in bone regeneration. These structures are made of sheets of the chemical element carbon that are ...
Unretouched triangular microlithic projectile points have been identified from their impact traces in the oldest occupation layers of the Obi-Rakhmat site in Uzbekistan, dating to 80,000 years ago. Their size corresponds ...
Each year, bacterial infections are responsible for roughly 7.7 million deaths worldwide, with this problem further exacerbated by rising antibiotic resistance. Not only are wound infections increasingly difficult to treat, ...
In a study published in Cell Research, researchers have identified a fibrous-layer resident subpopulation of P-SSCs labeled by Angptl7. They found that these cells are crucial for bone fracture repair by mediating endochondral ...
Teeth function not only because of the hard enamel on the surface, but also because they have roots that anchor them firmly in the jawbone beneath the gums. Eating, speaking, and maintaining the shape of the face—teeth are ...
