Nanoparticles Help Untangle Alzheimer’s Disease Amyloid Beta Plaques

ROCKVILLE, MD – Scientists are still a long way from being able to treat Alzheimer’s Disease, in part because the protein aggregates that can become brain plaques, a hallmark of the disease, are hard to study.

How SARS-CoV-2’s Sugar-Coated Shield Helps Activate the Virus

ROCKVILLE, MD – One thing that makes SARS-CoV-2, the virus that causes COVID-19, elusive to the immune system is that it is covered in sugars called glycans.

Technique Can Label Many Specific DNAs, RNAs, or Proteins in a Single Tissue Sample

A new technique can label diverse molecules and amplify the signal to help researchers spot those that are especially rare. Called SABER (signal amplification by exchange reaction), Peng Yin’s lab at Harvard’s Wyss Institute first introduced this method last year and since have found ways to apply it to proteins, DNA and RNA.

New High-Throughput Method to Study Gene Splicing at an Unprecedented Scale Reveals New Details About the Process

Genes are like instructions, but with options for building more than one thing. Daniel Larson, senior investigator at the National Cancer Institute, studies this gene “splicing” process, which happens in normal cells and goes awry in blood cancers like leukemia.

What Induces Sleep? For Fruit Flies It’s Stress at the Cellular Level

Sleep-deprived fruit flies helped reveal what induces sleep. University of Oxford researchers Anissa Kempf, Gero Miesenböck, and colleagues reveal that fruit fly sleep is driven by oxidative stress, the imbalance of free radicals and antioxidants in the body.

Like a Microscopic Mars Rover, a New Technique Tracks Individual Protein Movement on Live Cells

The piece of gold that Richard Taylor was thrilled to track down weighed less than a single bacterium. Taylor, a postdoctoral fellow at the Max Planck Institute, was working to follow individual nanogold-labeled molecules that move just nanometers, billionths of a meter.

Researchers Show How Ebola Virus Hijacks Host Lipids

Robert Stahelin studies some of the world’s deadliest viruses. Filoviruses, including Ebola virus and Marburg virus, cause viral hemorrhagic fever with high fatality rates. Stahelin, professor at Purdue University, examines how these viruses take advantage of human host cells.
