To determine why more aerobically fit individuals have better memories, scientists used magnetic resonance elastography (MRE), which measures the elasticity of organs, and found that fit individuals had a firmer, more elastic hippocampus—a region of the brain associated with memory.

USM Names David W. Wise Director of Maryland Momentum Fund

The University System of Maryland (USM) has named business innovator David W. Wise, MALD, as director of the Maryland Momentum Fund (MMF), a $25 million fund to support startups formed within the system’s 12 institutions and its incubators. He joined USM on July 24.

Genetically Engineered Ants Showcase Smell’s Role in Social Behavior

After creating mutant Indian jumping ants with no sense of smell, HHMI Investigator Danny Reinberg and colleagues saw profound abnormalities in the ants’ behavior and brains. The results show that the sense of smell is fundamental to maintaining colony harmony.

Iowa State's Anupam Sharma is running computer simulations to learn how owl wings manipulate air flow, pressure and turbulence to create silent flight. He and his partners hope their studies will produce practical ideas for making quiet aircraft and wind turbines.

When DNA Evidence Challenges Ideas of A Person’s Racial Purity, White Supremacists Use a Decision Tree to Affirm or Discount the Results

Now that science can determine a person’s racial and ethnic origins from a cheek swab, those devoted to ideas of racial “purity,” are employing methods of mind games and logic twists to support their beliefs despite facing evidence of their own multiracial heritage.

Sweet! Sugar-Coated Probe Yields Better Acid Test

When our cells’ acid-alkaline balance goes wrong, it can go wrong in a big way—think cancer and cystic fibrosis. New fluorescent probes make it easier to detect pH and sweetened the deal by adding sugar to his acid-sensitive probes, making them much friendlier to living tissue.

A Metabolic Pathway That Feeds Liver Cancer

A little-studied gene may explain how some liver cancer cells obtain the nutrition they need to proliferate, according to new research from the University of Maryland.

New Version of DNA Editing System Corrects Underlying Defects in RNA-based Diseases

yeo_RCas9.jpg

Until recently, CRISPR-Cas9 gene editing could only be used to manipulate DNA. In 2016, University of California San Diego School of Medicine researchers repurposed the technique to track RNA in live cells in a method called RNA-targeting Cas9. In a study published August 10 in Cell, the team took RCas9 a step further: they corrected molecular mistakes that lead to microsatellite repeat expansion diseases, which include a type of ALS and Huntington's disease.

Microbiome researchers Rob Knight, PhD, University of California San Diego, Jeffrey Gordon, MD, Washington University School of Medicine in St. Louis, and Norman Pace, PhD, University of Colorado Boulder, will share this year’s Massry Prize, splitting the $200,000 honorarium. These researchers lead a field that works to produce a detailed understanding of microbiomes andand methods for manipulating them for the benefit of human and environmental health.
