New research explores theories about aging and death in plants

(Phys.org) —According to Benjamin Franklin, "nothing can be said to be certain, except death and taxes." But what if Franklin had it wrong—at least about death? University of Georgia ecologist Richard P. Shefferson explored ...

Japan scientists launch freeze-dry animal sperm bank

Japanese scientists have launched a sperm bank for endangered animals that uses freeze-drying technology they hope could one day help humans recreate animal populations on other planets, the chief researcher said Wednesday.

Genomic and computational tools provide window to distant past

Out of the estimated 23,000 or more genes in the human genome, about 100 of them will differ—they will be present or not—between any two individuals. Genes lost or gained over time result from evolution and adaptation, ...

Research update: Genome editing becomes more accurate

Earlier this year, MIT researchers developed a way to easily and efficiently edit the genomes of living cells. Now, the researchers have discovered key factors that influence the accuracy of the system, an important step ...

Sexual reproduction only second choice for powdery mildew

Powdery mildew is one of the most dreaded plant diseases: The parasitic fungus afflicts crops such as wheat and barley and is responsible for large harvest shortfalls every year. Beat Keller and Thomas Wicker, both plant ...

Enhancing RNA interference

Nanoparticles that deliver short strands of RNA offer a way to treat cancer and other diseases by shutting off malfunctioning genes. Although this approach has shown some promise, scientists are still not sure exactly what ...

Capsella provides insight into the genomic results of selfing

About 200,000 years ago, Capsella rubella began self fertilizing and split from C. grandiflora. To study the effects of selfing on C. rubella's genome, the Department of Energy Joint Genome Institute sequenced and compared ...
