A large segment of a Chinese rocket is expected to make an uncontrolled re-entry into the Earth's atmosphere on the weekend, but Beijing has downplayed fears and said there is a very low risk of any damage.

The most comprehensive study of the family tree for legumes, the plant family that includes beans, soybeans, peanuts, and many other economically important crop plants, reveals a history of whole-genome duplications. The study also helps to uncover the evolution of genes involved in nitrogen fixation—a key trait likely important in the evolutionary spread and diversification of legumes and vital for their use as "green manure" in agriculture. To reconstruct the family tree, researchers compared the... Читать дальше...

A bacterial protein helps to stop transcription—the process of making RNA copies of DNA to carry out the functions of the cell—by causing the cellular machinery that transcribes the DNA to pause at the appropriate spots in the genome. The protein, known as NusG, pauses the transcription machinery at specific DNA sequences to facilitate what is called "intrinsic termination" and prevent unwanted transcription that could disrupt cellular function.
