Understanding the genomic signature of coevolution
Limnologists and other researchers show that rapid genomic changes during antagonistic species interactions are shaped by the reciprocal effects of ecology and evolution.

Fungal invasion of pancreas creates cancer risk
Certain fungi move from the gut to the pancreas, expand their population more than a thousand-fold, and encourage pancreatic cancer growth, a new study finds.
Read morePatient cancer cells reliably grow on new 3D scaffold, showing promise for precision medicine
A new 3D structure for growing cell cultures could enable doctors to test medications on model tumors grown from a patient's own cells, according to a team of engineers and cancer researchers.
Read moreHard as ceramic, tough as steel: Newly discovered connection could help design of nextgen alloys
A new way to calculate the interaction between a metal and its alloying material could speed the hunt for a new material that combines the hardness of ceramic with the resilience of metal.

Phorbiplatin is a new anti-cancer prodrug that can be controllably activated by red light. With its unique 'on-site' activation characteristic, this new prodrug can effectively kill cancer cells and minimize damage to normal tissues.
Read moreCleaning with bleach could create indoor air pollutants
For generations, people have used chlorine bleach to clean and disinfect their homes. However, researchers have now discovered that bleach fumes, in combination with light and a citrus compound found in many household products, can form airborne particles that might be harmful when inhaled by pets or people.
Read moreCRISPRed fruit flies mimic monarch butterfly, and could make you vomit
Monarch butterflies and a few other insects evolved essentially the same genetic mutations allowing them to eat toxic milkweed without getting sick. Monarch butterflies and caterpillars store the toxins to deter predators. Scientists have now used CRISPR gene editing to make these same mutations in fruit flies, successfully conferring toxin resistance. This is the first time an animal has been genetically engineered to eat a new food and employ a new type of deterrence.

Understanding the causes and consequences of Late Quaternary megafaunal extinctions is increasingly important in a world of growing human populations and climate change. A review highlights the role that cutting-edge scientific methods can play in broadening the discussions about megafaunal extinction and enabling insights into ecosystems and species-specific responses to climate change and human activities.
Read moreEnvironmental toxins impair immune system over multiple generations
New research shows that maternal exposure to a common and ubiquitous form of industrial pollution can harm the immune system of offspring and that this injury is passed along to subsequent generations, weakening the body's defenses against infections such as the influenza virus.
Read moreResearchers identify molecular process that could accelerate recovery from nerve injuries
Researchers have discovered a molecular process that controls the rate at which nerves grow both during embryonic development and recovery from injury throughout life.
