May 1, 2015 — The CRISPR/Cas system, which is based on chemically synthesized small RNAs and commercially available Cas9 enzyme, has enabled long gene-cassette knock-in in mice with highest efficiency ever ... read more

Apr. 30, 2015 — Scientists have crunched the numbers and the results are clear. For every degree that global temperatures rise, more species will become extinct. Overall, the study predicts a nearly 3 percent ... read more

Apr. 30, 2015 — High-resolution imaging of plant cells is important in many plant studies, and the most commonly used method is scanning electron microscopy (SEM). But SEM can have limitations, including damage to ... read more

Viruses: You've Heard the Bad; Here's the Good

Apr. 30, 2015 — Viruses, like bacteria, can be important beneficial microbes in human health and in agriculture, researchers say, following a review of the current literature on beneficial ... read more

MarkerMiner 1.0: An Easy-to-Use Bioinformatics Platform for DNA Analysis in Angiosperms

Apr. 30, 2015 — Researchers have developed MarkerMiner, a new software that simplifies analysis of next-generation sequencing data in angiosperms. MarkerMiner is an automated, open-source, bioinformatics workflow ... read more

Apr. 30, 2015 — An international team of scientists has used the fossil record during the past 23 million years to predict which marine animals and ecosystems are at greatest risk of extinction from human impact. ... read more

Settling an Old Debate: Researchers Solve a Lingering Mystery of Cancer Cell Biology

Apr. 30, 2015 — German biologist Theodor Boveri observed early in the last century that cancer cells often harbor multiple copies of a subcellular structure that he had previously named the centrosome. He was also ... read more

Mammals Not the Only Animals to Feed Embryo During Gestation

Apr. 30, 2015 — For over a century, the scientific understanding of matrotrophy of an embryo developing inside a mom's body has come from vertebrates. This process was thought to be infrequent among the other ... read more
