Why We Get Cancer: Mutations Might Not Be Always the Cause
Researchers find that mutations are not the only drivers of tumor formation and that epigenetic alterations could be involved too. Continue reading Why We Get Cancer: Mutations Might Not Be Always the Cause
DNA Detectives: How scientists are using DNA from the environment to see the unseen
by Sanjana Kulkarnifigures by Swathy Karamchedu Forensic DNA testing has become crucial in criminal investigations and legal proceedings. DNA has linked people to crime scenes using hair or blood and exonerated wrongfully convicted individuals. This type of DNA is called environmental DNA (eDNA) because it is collected from the environment, rather than from a person. Scientists have also begun analyzing eDNA from non-human organisms. All … Continue reading DNA Detectives: How scientists are using DNA from the environment to see the unseen
Researchers identify regions in the human genome that are consistent across primates
After generating 187 new genomes from primate species, researchers found a large fraction of the human genome that is highly conserved across evolution. Continue reading Researchers identify regions in the human genome that are consistent across primates
Machine learning can rapidly identify brain tumor type to guide surgery
Knowing the type of brain tumor can help determine how aggressive the surgeon should be in removing it. A new study has created a procedure using machine learning and DNA sequencing to quickly classify tumors and guide the surgery while it is happening. Continue reading Machine learning can rapidly identify brain tumor type to guide surgery
Scientists create a customizable circuit made from DNA
A group of researchers from Shanghai built a customizable circuit that operates entirely with DNA, a groundbreaking step towards general-purpose DNA computing. Continue reading Scientists create a customizable circuit made from DNA
RNA plays a newly discovered role in the development of cancer
by Carlos Moralesfigures by Shreya Mantri Our cells perform extraordinary functions using information stored in their genetic material, known as DNA. Changes in DNA, known as mutations, can make cells behave erratically, which may lead to cancer. But how does cancer begin? A new model proposes that RNA — the molecular link between DNA and proteins — is at the heart of this phenomenon. How … Continue reading RNA plays a newly discovered role in the development of cancer

Dissecting cancer complexity across space and time
by Jackson Weirfigures by Jasmin Joseph-Chazan Why is cancer so difficult to cure? Why do available treatments only help a subset of patients? Why are some cancers more aggressive than others? These are questions that clinicians, scientists, and the public have pondered for generations. As it turns out, the answers are complicated because cancer biology is complicated. Luckily, new tools and technologies are helping us … Continue reading Dissecting cancer complexity across space and time
Solving Scientific Problems by Asking Diverse Questions
by Piyush Nandafigures by Shreya Mantri Gravity has been apparent for thousands of years: Aristotle, for example, proposed that objects fall to settle into their natural place in 4th century BC. But it was not until around 1900, when Issac Newton explained gravity using mathematical equations, that we really understood the phenomenon. Why didn’t thinkers before Newton think about gravity the way he did? Scientific … Continue reading Solving Scientific Problems by Asking Diverse Questions
