Cell function is determined by how DNA is expressed into proteins. That process includes two main steps—transcription, when messenger RNA (mRNA) makes copies of active genes; and translation, when mRNA guides protein assembly.
When doctors and scientists want to see inside a body, magnetic resonance imaging (MRI) is a powerful tool. MRI can noninvasively capture detailed images of the body's muscles, organs, and bones. It can monitor blood flow ...
When a singer belts out a tune while a guitar player strums along, sound waves travel through the air, driving collective oscillations of the molecules within. Meanwhile, at the quantum level, something similar is going on. ...
Like so much else in nature, the human visual system has both a complex structure and functional efficiency that is difficult for scientists to replicate. The system is both a sensor and a processor, with the eyes and the ...
Bacteria from the Middle East have caused precipitation all the way out in California. The same bacteria, which are known to attack plants, have also been found embedded within lumps of hail in West Africa.
Proteins are critical to life—and to industry. There are countless proteins that could be engineered to treat and even cure serious diseases and cellular dysfunctions. Industrial applications are similarly promising, with ...
How do sea squirts stay attached to rocks amid crashing waves and strong currents? Recent research has revealed that sea squirts do not simply secrete adhesive substances. Instead, they possess a unique system where they ...
Researchers at the University of Pennsylvania have developed ApexGO, a novel, AI-powered method for turning promising but imperfect antibiotic candidates into more potent ones. Unlike many existing AI approaches to antibiotic ...
When scientist J. Craig Venter and his team announced in 2010 that they had created the first cell controlled by a fully synthetic genome, it marked a turning point in how scientists think about life.
Just as the human body relies on organs such as the heart or liver for essential functions, cells depend on their own tiny organs, or organelles, to carry out vital tasks, including transporting nutrients, removing waste, ...
