In a recent study from UCSF and MIT, researchers found that they could identify evolutionary differences in biological function by comparing the results of CRISPR screens in humans and chimpanzees. Continue reading Scientists compare CRISPR screens in chimpanzee and human cells to understand evolution
by Mara Casebeer Most bacteria, like the common E. coli, are around a micron in length – less than a tenth of the width of a strand of human hair and invisible without a microscope. Recently, scientists discovered a bacterium, Candidatus (Ca.) Thiomargarita magnifica, that is almost 10,000 times longer than E. coli. Ca. T. magnifica cells were found attached to sunken leaves in the … Continue reading How this Long Bacterium Beats the Diffusion Limit

Lightning is less common over the ocean than land, new research
suggests that aerosols such as salt from sea spray may be the reason. Continue reading Seaspray, lightning away: Salt may explain why lightning strikes less over the ocean
No one can escape aging. But scientists have found that turtles and tortoises live much longer and barely age compared to humans and other animals. Continue reading Turtles barely age compared to humans and other animals
Researchers show that symbiotic bacteria can evolve in the gut to become harmful, providing clues to how autoimmune diseases develop. Continue reading Gut Microbiome Bacteria Can Evolve to Cause Autoimmune Diseases
A new look at the louse family tree has revealed that many lice hosted by mammals, including the human head louse, have coevolved with mammals over tens of millions of years. Continue reading Itching for a change? Some lice have evolved alongside their hosts for millions of years.
by Misha Guptafigures by Xiaomeng Han For close to two centuries, humans have been studying the biological past using fossil records. In recent history, we have added the ability to reconstruct the sequence of our DNA to our arsenal. Furthermore, phylogenetic trees (structures that define the evolutionary relationships in the line of descent from a common ancestor) have been created for all manners of organisms, … Continue reading Viral Fossil Records: A Look into the Past! (and the Future?)
by Ariel Hairstonfigures by MacKenzie Mauger Our lives are stuffed with opportunities for excitement and stimulation. You might wake up in the morning and find yourself staring at your modest collection of succulents, or that small oil painting you bought at a flea market. The first moments of your day might be spent taking a walk around the block, the smell of tree bark hanging … Continue reading Home Decor and the Hippocampus: How environmental enrichment can enhance brain function
