Cabbage White Butterflies Utilize Two Gut Enzymes For Maximum Flexibility In Deactivating Mustard Oil Bombs

Depending on the composition of the defensive toxins of their host plants, the insects use two different complementary enzymes for detoxification

Mapping the Communications Hub of the Brain

The thalamus acts as central communications hub for the brain, relaying information from the senses and other brain parts.

More Flexible Than Previously Thought: Worms Give Us New Insights Into The Evolution And Diversification Of TGF-b Signaling Pathways

The TGF-ß cellular signaling network, essential to various functions in all metazoans and also involved in many severe human pathologies like autoimmune diseases and cancer, is more flexible than previously thought.

Nematode Teeth Consist Of Chitin

Genetically modified worms may make us rethink invertebrate evolution

500 Million Year-Old Fossils Reveal Answer To Evolutionary Riddle

An exceptionally well-preserved collection of fossils discovered in eastern Yunnan Province, China, has enabled scientists to solve a centuries-old riddle in the evolution of life on earth, revealing what the first animals to make skeletons looked like.

The Three Dimensions Of A Flower

To better understand the evolution of flowers, a research team in biology from Université de Montréal, the Montreal Botanical Garden and McGill University have succeeded in using photogrammetry to quickly and precisely build, in three dimensions, a model of a flower from two-dimensional images.

Earth Might Be Experiencing 7th Mass Extinction, Not 6th

550-million-year-old creatures’ message to the present

Weizmann Institute scientists pursue evolution of sphingolipids, implications for Darwinian theory

Sphingolipids are a type of fatty material (lipids) in cell membranes that are critical for membrane structure and cell signaling. When they malfunction, sphingolipids can cause human illnesses, such as Gaucher disease, a rare inherited metabolic disorder.

Ancient DNA from Medieval Germany Tells the Origin Story of Ashkenazi Jews

Research team analyzed genome-wide data for 33 Jewish individuals from 14th century Erfurt, Germany

Going To The ‘Femoral Head’ Of The Class To Explain Dinosaur Evolution

Dinosaurs — and birds — wouldn’t have been able to stand on their own two feet without some radical changes to their upper thigh bones. Now, a new study by Yale paleontologists charts the evolutionary course of these leggy alterations.

Genetic study shows human influence in northward spread of European wall lizards

A study of the mitochondrial DNA of the common wall lizard shows that their spread from Italy into southeastern Europe was probably aided by human influence.

History of Rhino Images Illustrates Changing Human-Rhino Relations and Horn Size

An international team of scientists, led by the University of Helsinki, has demonstrated that image databases can be used as an alternative to museum collections when studying long-term changes in human-nature interaction and as material in ecological and evolutionary research.

University College London geneticists suggest origin of genetic code in pre-cellular metabolism

Proceeding from a concept called the proto-metabolism hypothesis, geneticists at the University College London (UCL) provide a new framework for the origin of the genetic code in protocells growing by CO2 fixation.

Vocal Communication Originated over 400 Million Years Ago

Acoustic communication is not only widespread in land vertebrates like birds and mammals, but also in reptiles, amphibians and fishes.

Black Death Shaped Evolution of Immunity Genes, Setting Course for How We Respond to Disease Today

An international team of scientists who analyzed centuries-old DNA from victims and survivors of the Black Death pandemic has identified key genetic differences that determined who lived and who died, and how those aspects of our immune systems have continued to evolve since that time.

A New Window into Plants of the Past

Researchers from Université de Montréal and the University of Minnesota have developed a fast, nondestructive way of estimating how millions of dried plant specimens interacted with their environment.
