Desert dust collected from glacier ice helps document climate change

Researchers from The Ohio State University are using dust trapped in glacier ice in Tibet to document past changes in Earth's intricate climate system—and maybe one day help predict future changes.

Efficient mRNA delivery by branched lipids

Messenger RNA (mRNA) are biological molecules that transfer the information coded by genes in the nucleus to the cytoplasm for protein synthesis by ribosomes. mRNA sequences can be designed to encode specific proteins; the ...

The untapped potential of RNA structures

The human genome has just over 20,000 genes coding for proteins. Yet, it produces at least ten times that many different non-coding RNA molecules, which can often take on more than one shape. At least some of this RNA structurome ...

A new control system for synthetic genes

Using an approach based on CRISPR proteins, MIT researchers have developed a new way to precisely control the amount of a particular protein that is produced in mammalian cells.

Proof-of-concept study advances potential new way to deliver gene therapy

Johns Hopkins Medicine researchers say they have successfully used a cell's natural process for making proteins to "slide" genetic instructions into a cell and produce critical proteins missing from those cells. If further ...

New study shows how to learn the equations of cell migration

When you cut yourself, a mass migration begins inside your body: Skin cells flood by the thousands toward the site of the wound, where they will soon lay down fresh layers of protective tissue.

Scientists discover dual-function messenger RNA

For the very first time, a study led by Julian Chen and his group in Arizona State University's School of Molecular Sciences and the Biodesign Institute's Center for the Mechanism of Evolution, has discovered an unprecedented ...

MESSENGER reveals a more dynamic Mercury surface

Compared with Earth, the surfaces of most other objects in the solar system appear largely static. Planetary scientists have long believed that impacts from space debris are the principal source of change on these surfaces ...

Can astronomers predict which stars are about to explode as supernovae?

In a recent study submitted to High Energy Astrophysical Phenomena, a team of researchers from Japan discuss strategies to observe, and possibly predict precursor signatures for an explosion from Local Type II and Galactic ...
