Researchers 3-D print lifelike artificial organ models

Matter and energy from Science Daily Feed - Wed, 12/06/2017 - 9:26am
A team of researchers has 3-D printed lifelike artificial organ models that mimic the exact anatomical structure, mechanical properties, and look and feel of real organs. These patient-specific organ models, which include integrated soft sensors, can be used for practice surgeries to improve surgical outcomes in thousands of patients worldwide.

United States has lost dominance in highly intense, ultrafast laser technology to Europe and Asia, new report finds

Matter and energy from Science Daily Feed - Wed, 12/06/2017 - 9:26am
The U.S. is losing ground in a second laser revolution of highly intense, ultrafast lasers that have broad applications in manufacturing, medicine, and national security, says a new report. Currently, 80 percent to 90 percent of the high-intensity laser systems are overseas, and all of the highest power research lasers currently in construction or already built are overseas as well.

Hydrogen gas from enzyme production

Matter and energy from Science Daily Feed - Wed, 12/06/2017 - 9:25am
Researchers have uncovered a crucial reaction principle of hydrogen-producing enzymes. The scientists investigated the production of molecular hydrogen in single-cell green algae. They were able to demonstrate how the enzyme succeeds in transferring two electrons in succession to two hydrogen ions and thereby assume stable intermediate states.

Flipping the electron spin

Matter and energy from Science Daily Feed - Wed, 12/06/2017 - 9:24am
When lithium-ion batteries are charged too quickly, metallic lithium gets deposited on the anodes. This reduces battery capacity and lifespan and can even destroy the batteries. Scientists have now presented a process that, for the first time ever, allows this so-called lithium plating process to be investigated directly. This puts new strategies for quick-charging strategies close at hand.

Smartphone health apps miss some daily activity of users

Computers and Math from Science Daily Feed - Wed, 12/06/2017 - 9:24am
The iPhone's Health app and its built-in pedometer miss a significant number of users' steps during a typical day, a new study has found. That's good news for people who self-monitor their physical activity; they are probably getting more exercise than they realize. But the results should raise some caution among researchers who want to tap into the smartphone's enormous potential for gathering health data.

Cell tissue must not freeze!

Matter and energy from Science Daily Feed - Wed, 12/06/2017 - 9:24am
Nature has evolved sugars, amino acids, and special antifreeze proteins as cryoprotectants. People use organic solvents and synthetic polymers as additives to prevent cell cultures from freezing damage. Now, scientists have combined both methods: They introduced polyproline, a polypeptide made of the natural amino acid proline, as an effective cryoprotectant for monolayers of cells.
