Researchers have developed a graphene-organic heterojunction transistor that can modulate photocurrent speed, magnitude, and direction using light. The device utilizes the effective exciton thickness limitation of an intermediate organic transport layer to achieve logic reversal under optical modulation.
Researchers at the Heidelberg Max Planck Institute for Nuclear Physics have investigated ultrafast fragmentation of hydrogen molecules in intense laser fields using a new method. They used the rotation of the molecule as an internal clock to measure the timing of the reaction triggered by a second laser pulse.
A KAUST team has developed a printable ink with high conductivity and transparency for use in solar panels and novel electromagnetic wave blocking. The ink's performance was demonstrated in a frequency selective surface, showing decent reflection across multiple frequencies and polarization insensitive results.
Researchers analyzed long-term phytoplankton data to understand climate change effects on ocean productivity and biodiversity. The study found a significant increase in warm-water species, suggesting an adaptation advantage under changing conditions.
A research team at POSTECH developed a machine learning technique that uses transcriptome information from artificial organoids to predict anti-cancer drug response. This method increases predictive accuracy by selecting only relevant biomarkers, which was previously limited by false signals in conventional machine learning.
Researchers at KAUST developed a new material that significantly improves the energy density of supercapacitors, enabling quick bursts of energy. The material uses covalent organic frameworks (COFs) with carefully selected molecular functional groups to overcome conductivity limitations.
Researchers at the University of Göttingen found that beetle larvae start using their brains before they are fully formed, defying conventional wisdom on insect intelligence. The study revealed that key parts of the brain's central complex are active in the larva, allowing it to orient itself in its environment.
The new photodetector achieves ultrasensitive detection, stable operation under extreme conditions, and ultrabroad spectrum detection exceeding 10μm.
The survey found that spine surgery had the highest number of medical malpractice suits among neurosurgeons. Fear of lawsuits influences their practice, with defensive medicine being a common response. The study highlights the need for transparent communication, better informed consent forms, and fair compensation to patients.
Scientists have discovered a key mechanism behind SINEUPs, which can amplify protein production by messenger RNAs. The research provides new insights into how these functional non-coding RNAs work and their potential to treat diseases caused by insufficient protein synthesis.
