Journal Club: Giving the brain something to do highlights the circuitry of smarts
Scientists conducting neuroimaging studies hope that their MRI scans will offer up patterns that predict traits related to intelligence, personality, disease, or even offer insights into a patient’s clinical symptoms or their chances of responding to a drug. But according … Continue reading

Journal Club: First observation of ‘superballistic’ electrons, flowing like a viscous fluid in graphene
Taking advantage of graphene’s special properties, physicists have experimentally observed a stream of record-breaking electrons that move with a conductance exceeding the limit theorists established decades ago. The researchers reported their findings recently in Nature Physics. For more than half … Continue reading

Journal Club: A physicist’s take on the age-old ecological puzzle of how species form communities
Ecologists have long searched for the rules that govern how individual species join together to form a community. Whether forest or desert, the problem is complex. Myriad factors influence a community’s composition and stability —from how strongly species compete to … Continue reading

Journal Club: A new, twisted topological insulator
About a decade ago, physicists began identifying and probing materials that suffer something of an identity crisis. On the surface of these crystals, electrons flow and form currents, like in a conductor. But in the interior, electrons are pinned and … Continue reading
Journal Club: Super-sensitive new microscope uses ultracold atoms to image magnetic fields at high precision
In recent years, physicists have developed an arsenal of sensitive, high-resolution tools to probe the smallest magnetic fields, revealing nanoscale subtleties lost in larger-scale measurements. An understanding of these structures can offer insights into exotic quantum materials. A new microscope … Continue reading
Journal Club: Finding new ways to store higher-density information with ferroelectric materials
Recent findings suggest early proof of principle for a new way to read, write and erase information in much smaller areas than conventional memory. The method entails ferroelectric thin films, which store information using the domains’ polarization directions like the … Continue reading

New simple theory developed of plastic deformation of metals
Scientists would like to design high-strength structural materials, but much about this work depends on laborious trial and error due to the complexity of plastic deformation — that is, how materials can deform irreversibly. Now researchers propose a unified theory … Continue reading

C. elegans synchronized swimming
When a group of nematodes gets together in any kind of liquid, they put on quite a show. Each worm waves its body rhythmically to propel itself along. But the waving isn’t all random—in a dense group of Caenorhabditis elegans, … Continue reading
Liquid metal powers a microfluidic pump
Increasingly researchers are developing lab-on-a-chip devices that can do the work of an entire lab on the area the size of a microchip. Pumps are needed to move tiny amounts of fluid from one chamber to another within these microfluidic … Continue reading
