Bystanders will intervene in nine-out-of-ten public fights to help victims of aggression and violence say researchers, in the largest ever study of real-life conflicts captured by CCTV. The findings overturn the impression of the “walk on by society” where victims are ignored by bystanders. Instead, the international research team of social scientists found that at

Scientists report they were unable to reproduce the results of a well-known study showing that people are less likely to cheat on a task after making a list of the Ten Commandments. Their findings are published in a Registered Replication Report (RRR) in Advances in Methods and Practices in Psychological Science, a journal of the

In the cell nucleus, the genomic DNA is packaged into a tightly condensed form, which is referred to as chromatin. The basic unit of chromatin organization is the nucleosome, a DNA-protein complex consisting of a defined length of DNA wrapped around a bead-like structure which is made of histone proteins. The individual nucleosomes are connected

Damage to DNA is a constant threat to cellular life, and so it is constantly monitored and detected by a family of enzymes called RNA polymerases, resulting in subsequent repair to maintain genome integrity. In a paper published this week in the journal PNAS, researchers at University of California San Diego School of Medicine, with

Researchers from the University of Illinois at Chicago are the first to describe why CRISPR gene editing sometimes fails to work, and how the process can be made to be much more efficient. CRISPR is a gene-editing tool that allows scientists to cut out unwanted genes or genetic material from DNA, and sometimes add a

It’s DNA, but not as we know it. In a world first, Australian researchers have identified a new DNA structure — called the i-motif — inside cells. A twisted ‘knot’ of DNA, the i-motif has never before been directly seen inside living cells. The new findings, from the Garvan Institute of Medical Research, are published
