Solar panels for yeast cell biofactories Posted: 15 Nov 2018 11:49 AM PST Scientists presents a highly adaptable solution to creating yeast biohybrids with enhanced metabolism driven by light energy. |
Nanofiber carpet could lead to new sticky or insulating surfaces Posted: 15 Nov 2018 11:49 AM PST Inspired by the extraordinary characteristics of polar bear fur, lotus leaves and gecko feet, engineering researchers have developed a new way to make arrays of nanofibers that could bring us coatings that are sticky, repellent, insulating or light emitting, among other possibilities. |
Warning: Chemical weapons risk during a period of very rapid scientific change Posted: 15 Nov 2018 11:49 AM PST Alarming examples of the dangers from chemical weapons have been seen recently in the use of industrial chemicals and the nerve agent sarin against civilians in Syria, and in the targeted assassination operations using VX nerve agent in Malaysia and novichok nerve agent in the UK. |
Rainforest vine compound starves pancreatic cancer cells Posted: 14 Nov 2018 09:03 AM PST Pancreatic cancer cells are known for their ability to thrive under extreme conditions of low nutrients and oxygen, a trait known in the cancer field as 'austerity.' The cells' remarkable resistance to starvation is one reason why pancreatic cancer is so deadly. Now researchers have identified a compound from a Congolese plant that has strong ''antiausterity'' potential, making pancreatic cancer cells susceptible to nutrient starvation. |
Posted: 14 Nov 2018 07:44 AM PST Researchers developed a versatile remote gaming interface that allowed experts as well as hundreds of citizen scientists all over the world through multiplayer collaboration and in real time to optimize a quantum gas experiment in a lab. Both teams quickly used the interface to dramatically improve upon the previous best solutions, that scientists had established after months of careful optimization. The experiment aims to unravel how humans solve complex, natural science problems. |
Next step on the path towards an efficient biofuel cell Posted: 14 Nov 2018 07:40 AM PST Fuel cells that work with the enzyme hydrogenase are, in principle, just as efficient as those that contain the expensive precious metal platinum as a catalyst. However, the enzymes need an aqueous environment, which makes it difficult for the starting material for the reaction -- hydrogen -- to reach the enzyme-loaded electrode. Researchers solved this problem by combining previously developed concepts for packaging the enzymes with gas diffusion electrode technology. |
When electric fields make spins swirl Posted: 14 Nov 2018 07:40 AM PST Scientists have reported the discovery of small and ferroelectrically tunable skyrmions. Published in Nature Materials, this work introduces new compelling advantages that bring skyrmion research a step closer to application. |
Scientists engineer a functional optical lens out of 2D materials Posted: 14 Nov 2018 07:40 AM PST Scientists have constructed functional metalenses that are one-tenth to one-half the thickness of the wavelengths of light that they focus. Their metalenses, which were constructed out of layered 2D materials, were as thin as 190 nanometers -- less than 1/100,000ths of an inch thick. |
Atomic parity violation research reaches new milestone Posted: 12 Nov 2018 10:15 AM PST Physicists have recently succeeded in observing parity violation in ytterbium atoms with different numbers of neutrons. |
Renewable energy cooperatives, an opportunity for energy transition Posted: 12 Nov 2018 10:15 AM PST Researchers have explored how renewable energy cooperatives have evolved. They have found that these cooperatives have developed a significant capacity to survive and adapt in response to the hostile context brought about by the economic and political regime. |
A step closer to 'design on demand' scaffolds for tissue regeneration Posted: 12 Nov 2018 10:15 AM PST Chemical engineers are determining how increasing the concentrations of polymers in solution changes the structure of cross-linked gels. |
