With abdominal etching, plastic surgeons help patients get ‘six-pack abs’

Even with a good diet and workout routine, some men and women have trouble getting the toned abdominal appearance they want. For these patients, a technique called abdominal etching can help in creating the classic ‘six-pack abs’ physique in men or three-vertical-line abdomen in women, reports a new study.

Defying the laws of physics? Engineers demonstrate bubbles of sand

A recent discovery explains a new family of gravitational instabilities in granular particles of different densities that are driven by a gas-channeling mechanism not seen in fluids. The team observed an unexpected Rayleigh-Taylor (R-T)-like instability in which lighter grains rise through heavier grains in the form of ‘fingers’ and ”granular bubbles, similar to the bubbles that form and rise in lava lamps.

Protecting damaged hearts with microRNAs

Once the heart is formed, its muscle cells have very limited ability to regenerate. After a heart attack, these cells die off and scar tissue forms, potentially setting people up for heart failure. A new study advances the possibility of using microRNAs — small molecules that regulate gene function — to regenerate heart muscle. In mice, two microRNAs that are abundant in developing hearts, miR-19a and miR-19b, repaired heart muscle and improved cardiac function after heart attack.

New genomics tool ECCITE-seq expands multimodal single cell analysis

ECCITE-seq (Expanded CRISPR-compatible Cellular Indexing of Transcriptomes and Epitopes by sequencing) allows researchers to perform high-throughput measurements of multiple modalities of information from single cells. The technique profiles different types of biomolecules from thousands of single cells in parallel, offering a breadth of information that can be used as readout in CRISPR-based pooled genetics screens.
