With the recent and highly publicized death of actor Robin Williams, depression is once again making national headlines. And for good reason. Usually, the conversation about depression turns to the… read more
While computers scientists find new ways to supercharge computers, a team of plant scientists have demonstrated that they can supercharge a plant. Hoping to speed up plant photosynthesis, researchers from the US… read more
In the last few centuries, medical advances have greatly lengthened lifespans. Among other causes, a central driver has been improved care at the beginning of life, when declining infant mortality rates have… read more
If you’re against killing animals for food and clothing or believe industrial farming is too resource intense, you may have given up some of life’s greatest pleasures. No juicy steak… read more

Why does the factory of life rely exclusively on four machines, the DNA bases A, G, C and T? To get an answer, scientists at Scripps Research Institute tried working with a host of other potential base molecules. Recently, they succeeded in inserting an extra set of bases into the DNA of an E. coli bacterium, and managed to get it to reproduce with the extra DNA bases in tact.
The mother’s nutrition at the time of conception can permanently and fundamentally affect physical characteristics of her offspring, according to a study just published in Nature Communications, by influencing the child’s epigenome.
