Potentially dangerous genes embedded within human DNA were once thought to be locked down by helpful DNA structures called heterochromatin. A researcher disputes that belief and hopes to change the paradigm even further.
Read moreBy mimicking the outer coating of pearls (nacre, or as it's more commonly known, mother of pearl), researchers have created a lightweight plastic that is 14 times stronger and eight times lighter (less dense) than steel and ideal for absorbing the impact of bullets and other projectiles.
Read moreScientists have discovered how a parasite responsible for spreading a serious tropical disease protects itself from starvation once inside its human host. The findings provide a new understanding of the metabolism of the Leishmania parasite and this new knowledge could potentially be used in its eradication.
Read moreCell biologists say they have, for the first time, directly observed and recorded in animal cells a pathway called branching microtubule nucleation, a mechanism in cell division that had been imaged in cellular extracts and plant cells but not directly observed in animal cells.
Read moreDomestic cats, like many other mammals, use smelly secretions from anal sacs to mark territory and communicate with other animals. A new study shows that many odiferous compounds from a male cat are actually made not by the cat, but by a community of bacteria living in the anal sacs.
