A mouth bacteria has starring role in colorectal cancer, study finds

Representative Fna C1 and Fna C2 strains co-cultured with human colon cancer cells. The grid shows the results of computational analysis of confocal imaging. Independent masks for cancer epithelial cells (grey), and intracellular bacterial cells (Fna C1 green, Fna C2 lavender) were generated. The masks were used to calculate the percent of cancer cells with…

Where does ‘us versus them’ bias in the brain come from?

“All animals are equal, but some are more equal than others” — this line from George Orwell’s 1945 classic ‘Animal Farm’ perfectly describes how bias operates in human societies. In a study published in May last year, psychologists explored how people subconsciously evaluate different racial groups. They screened responses from more than 60,000 participants belonging…

Does evolution of adaptation always take hundreds of years?

Evolution is often thought to take over hundreds or thousands of years. But a recent study has found a species of frog which has evolved over within about 25 years. The adaptation was spurred by salt. Researchers collected wood frog eggs from nine populations and allowed them to hatch into tadpoles. Whether populations of tadpoles…

Can the newly discovered organelle help engineer plants to fix nitrogen?

As proposed by Charles Darwin in the nineteenth century, natural selection, the engine that drives evolution, is how species adapt to their environments. Unlike the Neo-Darwinist consensus, the American evolutionary biologist Lynn Margulis did not believe that random genetic mutations were the sole cause of inherited variation. She came up with a new theory called…
