"Quantum jitter" mechanism behind the random mutations that drive evolution and cancer


Errors in DNA replication make evolution - and life as we know it - possible. But if there's too many of them, our genes would mutate out of control and we wouldn't survive. Now, a new study suggests that "quantum jitters" appear to tune the frequency of these spontaneous mutations to just the right level...

DNA of bacteria that live in the body passed from mother to child


Traits such as eye color and height are passed from one generation to the next through the parents' DNA, right? Not according to a new study by researchers at Washington University School of Medicine in St. Louis, who have shown that the DNA of bacteria that live in the body can pass a trait to offspring in a way similar to the parents' own DNA...

Study questions whether lab-grown cells are a faithful model for studying human disease


Studies of human diseases such as cancer rely on the use of laboratory-grown cell cultures that have often been grown for decades. Now, new research indicates that these cell cultures may not be a reliable copy of real tissue; a finding that casts doubt on the interpretation of many past studies...

Selfie shots used to monitor mental health


University of Rochester computer scientists have developed innovative software that turns smartphones into mental health monitoring devices. Describing the project at this week's American Association for Artificial Intelligence conference in Austin, Texas, researcher Jiebo Luo said the program analyzes "selfie" images and videos taken as the user engages with social media...

Evolutionary biology could reveal a universal basis for morality


Recent developments in science appear to indicate that the emergence of life in general and perhaps even rational life, with its associated technological culture, may be common throughout the Universe. Now, a new paper appearing in the journal Space Policy suggests this universal tendency toward complexity has distinctly religious overtones and may even establish a truly universal basis for morality...

Tiny vibrations could reveal extraterrestrial life


Motion is a trait of all life, but detecting the tiny movements of microorganisms requires incredible sensitivity. Now, Swiss scientists say they have developed an extremely sensitive yet simple motion detector that can be built using existing technology. The system has accurately detected bacteria and cancer cells, and its inventors think it could also detect extraterrestrial life...
