In APL Materials, researchers tested a molecular energy harvesting device that captures the energy from the natural motion of molecules in a liquid. Their work showed molecular motion can be used to generate a stable electric current. To create the device, they submerged nanoarrays of piezoelectric material in liquid, allowing the movement of the liquid to move the strands like seaweed waving in the ocean, except in this case the movement is on the molecular scale, and the strands are made of zinc oxide. When the zinc oxide material waves, bends, or deforms under motion, it generates electric potential.

Multiomics3 analysis that integrates different layers of profiles altogether is challenging, since the number of variables in profile substantially differ from each other. For instance, gene expression profile and genomic DNA methylation profile are often analyzed together, however, there are only tens of thousands of genes, whereas the number of DNA methylation sites are as many as tens of millions.

The nuclear reactions that power stellar explosions involve short-lived nuclei that are hard to study in the laboratory. Researchers used a combination of methods to measure a reaction where a neutron from a deuterium target is exchanged with a proton from a radioactive projectile, a reaction equivalent to a process in exploding stars.

Researchers have discovered a way to tune some semiconductors to reduce the amount of energy needed to eject electrons. The approach works by placing a bilayer coating of an insulator and graphene on top of the semiconductor then applying a voltage between the semiconductor and graphene. This bilayer approach could improve the efficiency of electromechanical devices and electron accelerators.

In Review of Scientific Instruments, scientists developed a microwave microstrip line planar resonator sensor tool to detect water adulteration in honey. The tool is compact, cost-effective, and easily fabricated. The microstrip line resonator sensor is fabricated on a dielectric substrate, which is an insulator that can efficiently support electrostatic fields, such as ceramic or glass. The team tested honey samples with varying water content and found that the sensor's resonance frequency consistently decreases with increased added water content.

Utilizando datos del telescopio Gemini Sur y de otros observatorios, los astrónomos encontraron un nuevo Evento Transitorio Óptico Azul Rápido (LFBOT por sus siglas en inglés), un tipo de poderosa explosión cósmica, de la cual no se sabe mucho. El estallido, al que se le apodó como “el Finch”, ocurrió en las afueras de una galaxia, a diferencia de otros LFBOT descubiertos hasta ahora que se hallaron anidando en galaxias de formación estelar. Esta observación pone en duda las teorías actuales sobre los orígenes de este tipo de eventos transitorios.

Using data from Gemini South and other observatories, astronomers have found a new Luminous Fast Blue Optical Transient (LFBOT), a powerful but poorly understood type of cosmic explosion. However, rather than being nestled in a star-forming galaxy like other LFBOTs discovered so far, the latest event, dubbed ‘the Finch’, occurred in the far outskirts of a galaxy. This observation calls into question leading ideas about the origins of these transient events.

•New Michigan State University research published in the journal Proceedings of the National Academy of Sciences shows that plants such as oak and poplar trees will emit more of a compound called isoprene as global temperatures climb. •Isoprene from plants represents the highest flux of hydrocarbons to the atmosphere behind methane. •Although isoprene isn’t inherently bad — it actually helps plants better tolerate insect pests and high temperatures — it can worsen air pollution by reacting with nitrogen oxides from automobiles and coal-fired power plants. •The new publication can help us better understand, predict and potentially mitigate the effects of increased isoprene emission as the planet warms.
