Light-modulated graphene-organic heterojunction transistors realizing photocurrent logic changes

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.

Rotation of a molecule as an "internal clock"

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.

Machine learning that predicts anti-cancer drug efficacy

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.

Beetle larvae think with a brain 'under construction'

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.

Neurosurgeons and malpractice suits

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.
