Message in a bottle: Info-rich bubbles respond to antibiotics

January 20, 2021 | News

Once regarded as merely cast-off waste products of cellular life, bacterial membrane vesicles (MVs) have since become an exciting new avenue of research, due to the wealth of biological information they carry to other bacteria as well as other cell types. These tiny particles, produced by most bacteria, can bud off from outer cellular membranes, travelling along cell surfaces and occasionally migrating into intercellular spaces. In a new study, Luis H. Cisneros and his colleagues describe...

A dose of facts: answering your COVID-19 vaccine questions

January 20, 2021 | News

With two COVID-19 vaccines authorized for emergency use in the United States and more in development, vaccination efforts are well underway worldwide.  The speed with which Moderna and Pfizer-BioNTech developed their vaccines, coupled with the internet’s ability to spread rumors more quickly than the coronavirus itself, means many people have questions about how the vaccines work and how safe and effective they are. We asked experts from Arizona State University to answer some...

Cyber-evolution: How computer science is harnessing the power of Darwinian transformation

January 18, 2021 | News

From a pair of simple principles of evolution—chance mutation and natural selection—nature has constructed an almost unfathomable richness of life around us. Despite our scientific sophistication, human design and engineering have struggled to emulate nature’s techniques and her inexhaustible inventiveness. But that may be changing. In a new perspective article, Stephanie Forrest and Risto Miikkulainen explore a domain known as evolutionary computation (EC), in which aspects of...

4 top ASU scholars named Regents Professors

December 22, 2020 | News

They are the best and brightest and have brought honor and distinguishment to their disciplines. They’re considered the top researchers that Arizona State University has to offer, and they’re getting their moment in the sun. Four ASU faculty are being honored with the title of Regents Professor: the most prestigious and highest faculty award possible. In order to receive this elite designation, they must be recognized by peers nationally and internationally. On Nov. 20, their names...

The far-reaching effects of mutagens on human health

December 21, 2020 | News

In order to survive, flourish and successfully reproduce, organisms rely on a high degree of genetic stability. Mutagenic agents, which can threaten the integrity of the genetic code by causing mutations in DNA, pose a serious risk to human health. They have long been implicated in a range of genetically inherited afflictions, as well as cancer, aging and neurodegenerative diseases like Alzheimer’s. It now appears that mutagenic threats to a cell’s subtle machinery may be far more...

How and why microbes promote and protect against stress

December 18, 2020 | News

More than half of the human body is not actually human: The body hosts approximately 100 trillion microbes. These bacteria, yeast and viruses, which make up the human microbiome, affect more than physical health. They also influence behavior and emotions. Some microbes prosper when the body is under stress, while other microbes contribute to buffering the body against stress. Athena Aktipis, associate professor of psychology at Arizona State University, used evolutionary theory to examine...

Hao Yan receives 2020 Foresight Institute Feynman Prize

December 15, 2020 | News

Hao Yan, director of the Biodesign Center for Molecular Design and Biomimetics at Arizona State University has been awarded the 2020 Foresight Institute Feynman Prize. The coveted award, named in honor of visionary physicist and Nobel laureate Richard Feynman, is given annually for outstanding contributions to nanoscience in two research categories: experimental and theoretical. This year’s award for experimental research recognizes Professor Yan’s significant contributions to the...

New and unexplored dimension in the study of protein-protein interactions

December 10, 2020 | News

Many proteins are required to maintain the structure, and to preserve the genetic integrity, of DNA. Sliding clamps are proteins that increase the efficiency of DNA replication. Without these proteins, cells would not be able to carry out continuous DNA synthesis, and organisms, from bacteria to humans, would not survive. Sliding clamps are ring-shaped proteins that encircle DNA and bind to the DNA polymerase, the enzyme that performs the actual DNA replication. They effectively organize and...

New recruit John McCutcheon elected as AAAS Fellow

December 4, 2020 | News

Five outstanding Arizona State University faculty spanning the physical sciences, psychological sciences and science policy have been named as Fellows of the American Association for the Advancement of Science (AAAS). ASU’s Leah Gerber, Andrew Maynard, Steven Neuberg, Ying-Cheng Lai and John McCutcheon are being honored for their career contributions to science, innovation or socially distinguished efforts to advance science and its applications. The AAAS, publisher of the journal...
