Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. Since the days of Max Planck and Albert Einstein, we know that light as well as electricity are quantized, meaning they come in tiny packets called photons and electrons. In a solar cell, the energy of a single photon is transferred to a single electron of the material, but no more than one. Only a few molecular materials like pentacene are an exception, where one photon is converted to two electrons instead. This excitation doubling, which is called exciton fission, could be extremely useful for high-efficiency photovoltaics, specifically to upgrade the dominant technology based on silicon. Researchers have now deciphered the first step of this process by recording an ultrafast movie of the photon-to-electricity conversion process, resolving a decades-old debate about the mechanism of the process.

Researchers have captured one of the fastest movements of a molecule called ferricyanide for the first time by combining two ultrafast X-ray spectroscopy techniques. They think their approach could help map more complex chemical reactions like oxygen transportation in blood cells or hydrogen production using artificial photosynthesis.

A major challenge in human genetics is understanding which parts of the genome drive specific traits or contribute to disease risk. This challenge is even greater for genetic variants found in the 98% of the genome that does not encode proteins. A new approach combines genetic association studies, gene editing, and single-cell sequencing to address these challenges and discover causal variants and genetic mechanisms for blood cell traits.

Storing data in DNA sounds like science fiction, yet it lies in the near future. Experts expect the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones in a hard drive but in the base pairs that make up DNA: AT and CG. Such a data center would take the form of a lab, many times smaller than the ones today.

A new study has found links at the atomic level between photosynthesis and exciton condensates -- a strange state of physics that allows energy to flow frictionlessly through a material. The finding is scientifically intriguing and may suggest new ways to think about designing electronics, the authors said.

All human beings are genetically very similar, sharing approx. 99.9% of the DNA code. The remaining 0.1% explains the natural differences between people, including our predisposition to hereditary diseases. Although sequencing of our genetic material is becoming a routine diagnostic analysis, it is unfortunately far from simple to determine whether specific small differences in our DNA affect our risk of developing disease. The usefulness of DNA sequencing is therefore often limited to the few cases where it is already known if a gene variant increases the risk of disease.

A research group has succeeded in regulating the flow of single molecules in solution by opening and closing the nanovalve mounted on the nanofluidic device by applying external pressure. The research group fabricated a device with a ribbon-like, thin, soft glass sheet on the top, and at the bottom a hard glass substrate having nanochannels and nanovalve seats. By applying external pressure to the soft glass sheet to open and close the valve, they succeeded in directly manipulating and controlling the flow of individual molecules in solution. They also observed an effect of fluorescence signal amplification when single fluorescent molecules are confined in the tiny nanospace inside the valve. The effect can be ascribed to the nanoconfinement, which suppresses the random motion of the molecules.

If you're a fan of arts and crafts, you're likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers now have a brand-new way to weld squishy stuff together without the need for glue at all. They've demonstrated a universal, 'electroadhesion' technique that can adhere soft materials to each other just by running electricity through them.

Scientists have developed a new extraction protocol for RNA-seq and metabolomic analysis, offering a more complete picture of cellular activity than either technique on its own. The protocol employs a streamlined extraction from a single sample, which reduces variation, improves efficiency, preserves data fidelity and maximizes use of precious biospecimens.
