Researchers at MIT and HMS have precisely measured the growth rates of single cells, revealing that mammalian cells divide when their growth rate hits a specific threshold. This breakthrough offers a possible explanation for how cells determine when to start dividing.
Researchers have made a major advance in efforts to regenerate damaged hearts by transplanting human cardiac muscle cells that electrically couple and beat in sync with the heart's own muscle. These grafts reduced the incidence of arrhythmias in a guinea pig model of myocardial infarction.
Researchers found that neutrophil elastase impairs insulin signaling and boosts resistance. Deletion of NE in obese mice improved insulin sensitivity. Neutrophils may hold the key to developing treatments for insulin resistance and diabetes.
A new study on malaria genomes reveals significant genetic diversity in Plasmodium vivax, a species of malaria that affects humans outside Africa, making it adept at evading drugs and vaccines. The research also sequenced the genome of Plasmodium cynomolgi, a close relative that infects Asian monkeys.
A breakthrough in technology has enabled the removal of unwanted toxins from crops, making oilseed rape more suitable for animal feed. This innovation could significantly enhance the use of rapeseed meal and promote more sustainable farming practices.
Research finds that grateful teens experience increased happiness, less depression and delinquency, and improved attitudes towards life. Over a four-year period, teenagers who developed greater gratitude showed significant improvements in well-being.
The study found that Shigella sonnei, a bacterium previously thought to be more common in developing countries, is now spreading globally due to its high levels of drug resistance. The researchers suggest that vaccine development will be crucial in controlling the disease.
Cancer cells respond differently to therapy based on their microenvironment, with fibroblasts sustaining DNA damage that promotes growth and resistance. The discovery could lead to more effective treatments by targeting the tumor microenvironment.
A new international study found that increased acidity affects shell size and weight, with a trend observed across multiple marine species. The research suggests that these changes will have significant impacts on humans and the ocean's large animals.
