Geneticists discover new wild goat subspecies via ancient DNA

Geneticists from Trinity College Dublin, together with a team of international collaborators, have discovered a previously unknown lineage of wild goats over ten millennia old. The research has just been published in the ...

Protein family shows how life adapted to oxygen

Cornell scientists have created an evolutionary model that connects organisms living in today's oxygen-rich atmosphere to a time, billions of years ago, when Earth's atmosphere had little oxygen—by analyzing ribonucleotide ...

'Kipferl': Guiding the defense against jumping genes

A large part of our DNA is made up of selfish repetitive DNA elements, some of which can jump from one site in the genome to another, potentially damaging the genome. Researchers from the Institute of Molecular Biotechnology ...

Researchers identify key player in cellular response to stress

An enzyme called Fic, whose biochemical role was discovered at UT Southwestern more than a dozen years ago, appears to play a crucial part in guiding the cellular response to stress, a new study suggests. The findings, published ...

Biologists glean insight into repetitive protein sequences

About 70% of all human proteins include at least one sequence consisting of a single amino acid repeated many times, with a few other amino acids sprinkled in. These "low-complexity regions" are also found in most other organisms.

Crops grown together cooperate better in just two generations

Growing multiple food crops together is a more sustainable farming practice mimicking highly productive wild plant communities. This process, known as intercropping, takes advantage of complementary features of different ...
