The heart can grow new muscle after an attack, living human tissue shows for the first time
Adult heart muscle has long been treated as tissue with very little capacity to replace cells lost during a heart attack. A new observation in living human samples complicates that picture: heart ...
The ATR–ATRIP kinase complex safeguards genome integrity by coordinating cellular responses to DNA damage and replication stress. Two recent cryo-EM studies resolve the structural basis of ATR–ATRIP ...

Mitotic chromosomes may assemble from pre-existing chromatin 'building blocks' during cell division
Inside each human cell, about 2 meters (6.6 feet) of genomic DNA must be accurately copied and equally transmitted to two daughter cells during cell division. To achieve this, the copied DNA is ...
The China Anti-Cancer Association's 2026 CONS guideline provides a GRADE-based framework for assessing risk, preventing, and ...
A flowering herb long used in traditional Chinese medicine has yielded a remarkable chemical treasure trove, and one of its ...
Some microorganisms thrive at temperatures far beyond anything humans could tolerate. The known growth record belongs to ...
The relevant role of pentose phosphate pathway (PPP) in cancer metabolic reprogramming has been usually outlined by studying glucose-6-phosphate dehydrogenase (G6PD). However, recent evidence suggests ...
A newly described amoeba found in California reproduced at 63°C, setting a reported record for eukaryotic life. The NASA-funded finding expands the known limits of complex cells and could inform the ...
Researchers found that cardiomyocytes in human hearts show increased mitotic activity after myocardial infarction, the medical term for a heart attack. In other words, surviving heart muscle cells can ...
Researchers have built a catalog of mitochondrial proteins found in six eukaryotic organisms — five parasites and one plant — ...
Every time a cell divides, its chromosomes must be distributed correctly between the two daughter cells. Central to this ...
Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. An immense variety of species of microbes, plants, insects, amphibians, reptiles, birds, ...
