Taking a Closer Look at Unevenly Charged Biomolecules

American Institute of Physics (AIP)

Clinicians most often monitor antibodies because these small proteins attach to antigens, or foreign substances, we face every day. Most biomolecules, however, have complicated charge characteristics, and the sensor response from conventional carbon nanotube systems can be erratic. A team in Japan recently revealed how these systems work and proposed changes to dramatically improve biomolecule detection. They report their findings in the Journal of Applied Physics.

Unraveling the Nature of ‘Whistlers’ from Space in the Lab

American Institute of Physics (AIP)

Scientists at the University of California, Los Angeles present research on a curious cosmic phenomenon known as “whistlers” -- very low frequency packets of radio waves that race along magnetic field lines. Appearing in the Physics of Plasmas, the study provides new insights into the nature of whistlers and space plasmas and could one day aid in the development of practical plasma technologies with magnetic fields, including spacecraft thrusters that use charged particles as fuel.

Demonstrated Natural Refrigerant Replacements Could Reduce Energy Costs and Conserve the Environment

American Institute of Physics (AIP)

The 1987 Montreal Protocol and the 1997 Kyoto Protocol called for countries around the world to phase out substances that deplete the ozone layer and cause global warming, but many HVAC systems still use synthetic refrigerants that violate those international agreements and inflict environmental damage. Recently, Iranian researchers investigated how natural refrigerants could be used in geothermal heat pumps to reduce energy consumption and operating costs. They report their findings in the Journal of Renewable and Sustainable Energy.

A Penetrable Fabric, Like Toilet Paper, Affects a Projectile’s Big Splash

American Institute of Physics (AIP)

Experts in fluid dynamics and kids jumping into a pool both know that an object falling into a liquid makes a splash. A new study finds that a single layer of a penetrable fabric – in this case, toilet paper – causes a wettable ball to make an especially tall splash, but additional layers can stop the splash entirely.

Simulating Biomolecules Just Got Faster and More Accurate

American Institute of Physics (AIP)

Researchers from the University of Florida and the Federal University of Mato Grosso do Sul in Brazil have used state of the art simulations to assess the effect of both pH and redox potential, or rate of electron transfer, on a biomolecule.

Observing the Mechanism of Metastasis for the First Time

American Institute of Physics (AIP)

Metastasis is a leading contributor to many deaths related to cancer, but the exact mechanisms for how broken cellular function appears in cells far removed from a cancer’s primary tumor remain an area of ongoing research. Scientists at the University of Minnesota Twin Cities confirmed a link between healthy-tumor hybrid cells and metastatic tumors for the first time in live animals. In APL Bioengineering, they discuss how they studied the distinct, heterogenous gene expression profiles found in human hybrid cells and how hybrid cells spontaneously occur in mouse models.

Renovations Lead to Big Improvement at Nuclear Astrophysics Lab

American Institute of Physics (AIP)

In nature, the nuclear reactions that form stars are often accompanied by astronomically high amounts of energy, a challenge for nuclear astrophysicists trying to study these reactions; the chances of re-creating such a spark are unfathomably low. However, after recent renovations to its accelerator, one laboratory reported record-breaking performance. Following six years of upgrades to the Electron Cyclotron Resonance Ion Source at the Laboratory for Experimental Nuclear Astrophysics, researchers report improved results, discussed in Review of Scientific Instruments.

Aboard the International Space Station, Researchers Investigate Complex Dust Behavior in Plasmas

American Institute of Physics (AIP)

400 kilometers above Earth, researchers examined waves in complex plasma under microgravity conditions and found that the microparticles behaved in nonuniform ways in the presence of varying electrical fields. They report some of the first findings from the Plasma-Kristall 4 experiment, a collaboration between the European Space Agency and the Russian State Space Corporation Roscosmos, in Physics of Plasmas.
