Researchers have developed a new device that harvests energy from the sweat on -- of all places -- your fingertips. To date, the device is believed to be the most efficient on-body energy harvester ever invented, producing 300 millijoules (mJ) of energy per square centimeter without any mechanical energy input during a 10-hour sleep and an additional 30 mJ of energy with a single press of a finger.

Scientists have developed a computational method based on large-scale molecular dynamics simulations to predict the cell-membrane permeability of cyclic peptides using a supercomputer. Their protocol has exhibited promising accuracy and may become a useful tool for the design and discovery of cyclic peptide drugs, which could help us reach new therapeutic targets inside cells beyond the capabilities of conventional small-molecule drugs or antibody-based drugs.

The absorption of energy from laser light by free electrons in a liquid has been demonstrated for the first time. Until now, this process was observed only in the gas phase. The findings open new doors for ultra-fast electron microscopy.

New research shows how control over self-propelled microswimmers could be achieved using exotic materials named 'nematic liquid crystals' - whose viscosity and elasticity can vary depending on the direction of an applied force.

New research has identified the processes that underpin the trajectories of microplastics below the ocean surface. The authors analyzed how biofouling -- the accumulation of algae on the surface of microplastics -- impacts the vertical movement of buoyant particles.

As the complexity of radiation therapy has grown, so too has the amount of data that goes into treatment machines. With more data comes more opportunity for errors in data transfer. A medical physics researcher is working to make those errors less likely.

A research team revealed a newly developed hydrogel-based flexible brain-machine interface.
