Meiosis: Chromosomes Dance And Pair Up On The Nuclear Membrane
Meiosis -- the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell -- is a major crossroads in all organisms reproducing sexually. Yet,...
Researchers begin to decipher metabolism of sexual assault drug
It's a naturally occurring brain chemical with an unwieldy name: 4-hydroxybutyrate (4-HB). Taken by mouth, it can be abused or used as a date-rape drug. Now, scientists have determined new...
Origin of life: Generating RNA molecules in water
A key question in the origin of biological molecules like RNA and DNA is how they first came together billions of years ago from simple precursors. Now, researchers have reconstructed...
Opposites attract: Monkeys choose mating partners with different genes
The world's largest species of monkey 'chooses' mates with genes that are different from their own to guarantee healthy and strong offspring, according to a new research study.
One for the Ages: Bristlecone Pines Break 4,650-Year Growth Record
Bristlecone pine trees dot the White Mountains in eastern California, giving the stark and rocky landscape one of its few highly visible signs of life. These gnarly-barked trees can survive...

New findings from an international team of researchers probing the nerve-insulating myelin sheath were bolstered by the work of Boston College biologists, who used x-rays to uncover how mutations affect...
Atomic-level snapshot catches protein motor in action
The atomic-level action of a remarkable class of ring-shaped protein motors has been uncovered by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) using a state-of-the-art protein crystallography beamline...
Alternative animal feed part of global fisheries crisis fix
Finding alternative feed sources for chickens, pigs and other farm animals will significantly reduce pressure on the world's dwindling fisheries while contributing positively to climate change, according to researchers.
Ants use bacteria to make their gardens grow
