A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. New research by University of Utah biologists sheds new light on how zebrafish heal heart tissue by comparing how this species responds to heart injury with medaka, a fish species that cannot regenerate cardiac tissue.

With more than 200 types of cancer and every cancer individually unique, ongoing efforts to develop precision oncology treatments remain daunting. In a new study published in the journal Nature Cancer, first author Sanju Sinha, Ph.D., at Sanford Burnham Prebys, with senior authors Eytan Ruppin, M.D., Ph.D., and Alejandro Schaffer, Ph.D., at the National Cancer Institute—and colleagues—describe a first-of-its-kind computational pipeline to systematically predict patient response to cancer drugs at single-cell resolution.

Astronomers and volunteer citizen scientists used Hubble's unique capabilities to identify a largely unseen population of very small asteroids. The treasure hunt required perusing 37,000 archived Hubble images spanning 19 years. The payoff? Finding 1,701 asteroid trails, with 1,031 of the asteroids previously uncatalogued. About 400 of these uncatalogued asteroids are smaller than 1 kilometer.

A new Moffitt Cancer Center study published in the journal Immunity offers insight into how lung cancer cells evade the protective immune system, potentially opening a door for novel antibody-based immunotherapies. Their study centers on a molecule called Jagged2, which plays a primary role in fueling the aggressiveness and immune evasion capacity of lung cancer.

Opioid dependence in Scotland remains high but largely stable, according to a new University of Bristol-led analysis published in Addiction today [18 April] and by Public Health Scotland. The study is the first to estimate the number of people dependent on opioid drugs (such as heroin), and who are in or could benefit from drug treatment, among Scotland’s population since 2015/2016 estimates were published.

Microbiologists do not fully understand how bacteria’s genes relate to their life strategies. Now, by analyzing large DNA sequencing datasets from around the globe, researchers discovered a new way of categorizing the dominant life strategies of soil bacteria based on their genes. This technique allowed the researchers to link different life strategies with specific climate and soil conditions.
