A membrane (red outer boundary) encapsulates actin (white lines), the protein building blocks of the cytoskeleton and tissues. The actin was polymerized by coupling ATP synthesis with artificial organelles (green dots) inside the membrane. Credit: Image courtesy of the Disease Biophysics Group/Harvard University

Researchers engineered a cell-like structure that harnesses photosynthesis to perform designer reactions. In the quest to build an artificial cell, there are two approaches: The first, reengineers the genomic software of a living cell. The second, focuses on cellular hardware, building simple, cell-like structures from the ground up that mimic the function of living cells...

Time evolution of the contour surfaces of the lapse α and the shift vector βi for the head-on collision of two puncture black holes of equal mass M=1 at times t=0,5,7,8,10M and t=15M, from top left to bottom right. Phys. Rev. D 97, 084053, 2018; doi:10.1103/PhysRevD.97.084053

Scientists develop simulation code for new generation of supercomputers. What happens when two black holes merge, or when stars collide with a black hole? This has now been simulated using a novel numerical method. The simulation code ‘ExaHyPE’ is designed in such a way that it will be able to calculate gravitational waves on the future generation of ‘exascale’ supercomputers.

The challenge in simulating black holes lies in the necessity of solving the complex Einstein system of equations...

An international team of scientists has created a tiny chemistry lab for a rover that will drill beneath the Martian surface looking for signs of past or present life. The toaster oven-sized lab, called the Mars Organic Molecule Analyzer or MOMA, is a key instrument on the ExoMars Rover, a joint mission between the European Space Agency and the Russian space agency Roscosmos, with a significant contribution to MOMA from NASA. It will be launched toward the Red Planet in July 2020...

Discovery could have big impact on semiconductor industry. A new experimental discovery, led by researchers at the University of Minnesota, demonstrates that the chemical element ruthenium (Ru) is the fourth single element to have unique magnetic properties at room temperature. The discovery could be used to improve sensors, devices in the computer memory and logic industry, or other devices using magnetic materials.

The use of ferromagnetism, or the basic mechanism by which certain materials (such as iron) form permanent magnets or are attracted to m...
