Human cells turn genetic instructions into proteins with great precision. Critical for the translation of this information are transfer RNAs, or tRNAs, small molecules that read the genetic code three letters at a time and bring the matching building blocks of proteins, the amino acids, to the cell's protein-making machinery, the ribosome.
Chinese American family caregivers of people with dementia reported a greater sense of control and competence in their caregiving roles and more positive views of caregiving after taking part in a seven-week digital support program, researchers at George Mason University found.
Archived observations appear to show a moving object in the far-distant outer solar system, but its reality is unclear
Scientists have discovered chemically confirmed traces of ancient blood inside 115-million-year-old dinosaur bones, challenging assumptions about how long biological molecules can survive. The extraordinary preservation could unlock new clues about dinosaur physiology and even help scientists search for ancient life elsewhere in the universe.
What happens when a technology becomes more powerful than its creators can fully understand?
A study of nearly 5,800 adults found that heart scans measuring calcium buildup in the arteries led to the same observed rate of major cardiovascular events as traditional risk assessments, despite recommending statins to far fewer patients. Surprisingly, patients advised to take statins based on their scans were nearly three times as likely to stick with their medication, raising intriguing questions about how doctors should identify and treat heart disease risk.
The risk of relying on uncertain carbon removal projects can now be quantified using a new standardized metric that can be applied across all such schemes, irrespective of the technology used.
University of Oregon geologist Becky Dorsey's latest research sheds light on the Siculo-Calabrian rift zone, a belt of faults spanning more than 100 miles (160 kilometers) in southern Italy. The new data could help improve earthquake hazard assessment in this seismically active region.
An international team of scientists has outlined how a new generation of artificial intelligence models could transform our understanding of ecosystems and help predict their responses to environmental change.
Living cells are one of the few materials that can replicate themselves, and this is crucial for tissue development and recovery from injury or illness. But making sure cell division only happens at the right time is essential; otherwise, unregulated replication can lead to problems like cancer.
Scientists have solved a mystery surrounding destructive beetles attacking blueberry bushes in North Carolina, identifying a species whose massive larvae can grow up to five inches long and destroy plant roots. Although farmers have reported damage for more than a decade, the insects responsible remained unidentified until researchers used DNA analysis to uncover the culprit.
After his mother was killed in a bear attack in Kashmir, Indian software engineer Mudasir Ali developed an online early-warning system to help people in the Himalayan region avoid dangerous encounters with wildlife.
