New process could make wood as strong as titanium alloys but lighter and cheaper. Engineers at the University of Maryland, College Par (UMD) have found a way to make wood more than 10X stronger and tougher than before, creating a natural substance that is stronger than many titanium alloys. “This new way to treat wood makes it 12 times stronger than natural wood and 10 times tougher,” said Liangbing Hu of UMD’s A. James Clark School of Engineering and the leader of the team that did the research, to be published on February 8, 2018 in the journal Nature...

Screenshot from video showing blood cells streaming through a “wound” and a clot forming. The red-stained cells are actually white blood cells. A green extracellular glue can be seen at the top of the wound; this is fibrin, which holds the clot together.

System responds to drugs; endothelium promotes clotting. Biomedical engineers have developed a miniature self-sealing model system for studying bleeding and the clotting of wounds. The researchers envision the device as a drug discovery platform and potential diagnostic tool...

The result shows the presence of a reinforced multilayer magnetic cage (orange and pink) in which the magnetic rope (blue) develops during the last hours before the eruption. Credit: © Tahar Amari et al. / Centre de physique théorique (CNRS/École Polytechnique).

Just one phenomenon may underlie all solar eruptions, according to researchers from the CNRS, École Polytechnique, CEA and INRIA. They have identified the presence of a confining ‘cage’ in which a magnetic rope forms, causing solar eruptions. It is the resistance of this cage to the attack of the rope that determines the power and type of the upcoming flare...

This is a ball-and-stick model of the molecular structure of the solar-fuel catalyst developed at Caltech. Blue represents iron atoms; green is nickel; red is oxygen; white is hydrogen. Credit: Caltech

Research uncovers mechanism behind water-splitting catalyst. Caltech researchers have made a discovery that they say could lead to the economically viable production of solar fuels in the next few years. For years, solar-fuel research has focused on developing catalysts that can split water into hydrogen and oxygen using only sunlight. The resulting hydrogen fuel could be used to power motor vehicles, electrical plants, and fuel cells. Since the only thing produced by burning hydrogen is water, no carbon pollution is added to the atmosphere.

In 2014, researchers in the lab of Harry Gray, Cal...
