New method enhances efficiency and accuracy of single cell RNA sequencing

In the era of personalized medicine, scientists are using new genetic and genomic insights to help them determine the best treatment for a given patient. In the case of cancer, the first step toward these treatments is an investigation into how tumor cells behave in an effort to figure out the best drugs to use to attack them.

Starved ticks try harder to find hosts

Ticks are hardy little brutes that can go as long as a year without a meal. Now scientists at the University of Cincinnati say the hungrier ticks are, the harder they try to find you or other hosts. The findings could have implications for the spread of tick-borne disease such as Lyme or Rocky Mountain Spotted Fever.

Mercury is not well detoxified by yelloweye rockfish, researchers find

It takes six months to get really good at accurately gauging the age of yelloweye rockfish. Because they can live for up to 120 years, this species is of particular interest to Benjamin Barst and scientists like him who study the effects of toxic chemicals on living organisms.

Vitamin D critical to early development of vertebrates, study suggests

New research from Portland State University finds vitamin D, or a lack thereof can trigger or suspend embryonic development in a species of fish. The study also provides evidence suggesting the vitamin is critical to the early development of vertebrates generally.

Scientists use cryo-EM to capture freeze-frames of molecule’s 'lock-and-load' on DNA

Pushing the limits of cryo-electron microscopy, University of California, Berkeley, scientists have captured freeze-frames of the changing shape of a huge molecule, one of the body's key molecular machines, as it locks onto DNA and loads the machinery for reading the genetic code.

Participation project calls for relaxing research ban on germline interventions

Are genetic defects allowed to be repaired by intervening with sperm or egg cells, or even human embryos? Thanks to genetic scissors such as CRISPR/Cas, such interventions in the germline could soon become a medical reality.

Researchers show how proteins interact in hypoxic conditions to facilitate mitochondrial fission

During a heart attack the supply of oxygen to heart cells is decreased. This reduced oxygen level, called hypoxia, causes the cell's powerhouses, the mitochondria, to fragment, impairing cell function and leading to heart failure. Until now, few details were known on how this important process occurs.
