    Medical errors increase with Daylight Saving Time. A report published in the Journal of General Internal Medicine by researchers using data from the Mayo Clinic Health System found that, over the course of eight years, losing an hour of sleep to Daylight Saving Time in the spring correlated to an 18.7% increase in medical mistakes specifically caused by human error in the following week. According to the study, most of the errors involved administering the wrong medication, or an incorrect dosage of a medication, to a patient.

    Is there extraterrestrial life on Venus? Scientists have launched spacecrafts, deployed robots, and peered through telescopes in the hopes of finding life on planets beyond Earth, but their efforts have been futile—until now, Deborah Netburn writes for the Los Angeles Times.

The researchers said their finding suggests that a living organism may have produced the gas on Venus, though they acknowledged that theory may sound a bit outlandish.

    Scientists discover new way to regenerate cardiac cells in pigs. In a study published Wednesday in Science Translational Medicine, scientists developed a "cell-less" approach to regenerate cardiac cells in pigs, Pratibha Gopalakrishna writes for STAT+. Previously, scientists had looked at whether cardiac cell transplants could quicken recovery after a heart attack, but they encountered a problem: The cells would not graft. Now, researchers have found an alternative to whole-cell transplants that involves exosomes—which are small, RNA packets secreted by cells.
