Social scientists build case for 'survival of the kindest'

(PhysOrg.com) -- Researchers at the University of California, Berkeley, are challenging long-held beliefs that human beings are wired to be selfish. In a wide range of studies, social scientists are amassing a growing body ...

Machine learning predicts antibiotic resistance spread

Genes aren't only inherited through birth. Bacteria have the ability to pass genes to each other, or pick them up from their environment, through a process called horizonal gene transfer, which is a major culprit in the spread ...

Gene editing 'blocks virus transmission' in human cells

Scientists have used CRISPR gene-editing technology to successfully block the transmission of the SARS-CoV-2 virus in infected human cells, according to research released Tuesday that could pave the way for COVID-19 treatments.

Could villains clone themselves to take over the world?

If asked about clones, most people think of evil sci-fi characters. However, in real life, the word "clone" often has broader, far more positive applications. Just as office workers replicate documents by using copy machines, ...

New technique illuminates DNA helix

Cornell researchers have identified a new way to measure DNA torsional stiffness—how much resistance the helix offers when twisted—information that can potentially shed light on how cells work.

Flipping the 'off' switch on cell growth

A protein known for turning on genes to help cells survive low-oxygen conditions also slows down the copying of new DNA strands, thus shutting down the growth of new cells, Johns Hopkins researchers report. Their discovery ...

'Jumping genes' create antibiotic resistance in bacteria

(PhysOrg.com) -- A small piece of foreign DNA recognizes when and where to slip into a bacterium's genetic code, allowing bacteria to genetically adapt to their environment -- and develop resistance to antibiotics, according ...
