There has long been a debate among biologists over whether the evolution of new traits requires new genes to evolve or whether they can arise simply from the recruitment of existing genetic pathways, says developmental biologist ...
Scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory have invented a new way to synthesize DNA that promises to be easier and faster, does not require the use of toxic chemicals ...
One of the most puzzling aspects of cancer is how cells inevitably manage to reactivate precisely those few genes that can turn them into tumors. One example, discussed at length here yesterday, is the restoration of telomerase ...
The discovery changes our understanding of the basic mechanism of photosynthesis and should rewrite the textbooks.
DNA is often referred to as the blueprint for life, however scientists have for the first time discovered a microbe that uses two different translations of the DNA code at random. This unexpected finding breaks what was thought ...
In humans and other mammals, the stem cells that give rise to all blood cells are located in the bone. But in fish, blood stem cells are found in the kidney. Since the late 1970s, when biologists first realized that blood ...
Spring is a busy time for bumblebee queens.
Some of Africa's oldest and biggest baobab trees—a few dating all the way back to the ancient Greeks—have abruptly died, wholly or in part, in the past decade, researchers said Monday.
Thanks to continued advances in genetic sequencing, scientists have identified virtually every A, T, C, and G nucleotide in our genetic code. But to fully understand how the human genome encodes us, we need to go one step ...
New, higher-quality assemblies of great ape genomes have now been generated without the guidance of the human reference genome. The effort to reduce "humanizing" discovery bias in great ape genomes provides a clearer view ...
