A UC Berkeley study found that social prairie voles lacking the receptor for oxytocin are slow to form friendships and less aggressive toward unfamiliar peers. This suggests a role for oxytocin in both the “approach” and “avoid” sides of maintaining friendships.
New research reported from the lab of Markita Landry announces scientists could make genetically engineering any type of plant—in particular, gene editing with CRISPR-Cas9—simple and quick. To deliver a gene, the researchers grafted it onto a carbon nanotube, which is tiny enough to slip easily through a plant’s tough cell wall. To date, most genetic engineering of plants is done by firing genes into the tissue—a process known as biolistics—or delivering genes via bacteria. Both are successful only a small percentage of the time, which is a major limitation for scientists seeking to create disease - or drought-resistant crops or to engineer plants so they’re more easily converted to biofuels.
A new technique developed by University of California, Berkeley, nanomaterials scientists has overcome the overcome the obstacles to delivering macromolecules using inexpensive lab equipment to efficiently infuse large macromolecules into cells. Called nanopore-electroporation, or nanoEP, the technique gently creates fewer than a dozen tiny holes in each cell that are sufficient to let molecules into the cell without traumatizing it. The pores heal rapidly afterward. In tests, more than 95 percent of the cells survived the procedure. .

Scanning tunneling microscope image of wide-band metallic graphene nanoribbon (GNR). Each cluster of protrusions corresponds to a singly-occupied electron orbital. The formation of a pentagonal ring near each cluster leads to a more than tenfold increase in the conductivity of metallic GNRs. The GNR backbone has a width of 1.6...
In this engaging article, meet Markita Landry, Assistant Professor of Chemical and Biomolecular Engineering, who runs the Landry Lab at UC Berkeley. Her lab works on developing nanomaterials to assist in the delivery of CRISPR-Cas9 systems in plants.
The carbon nanotubes Landry has developed are exceptionally strong, chemically versatile, and capable of near-infrared fluorescence—making them invaluable in diverse scientific applications.

Some scientists make discoveries that trigger a tidal wave of research. Some inspire so many others to join their scientific endeavor that a new field of research is born. But few people do the kind of extreme-impact work that helps...
