Opioid-based plant might not be best solution to curb habitual alcohol use

( Purdue University) A Purdue University team published a paper in the British Journal of Pharmacology examining the effects of kratom and the potential impacts on people with alcohol use disorder.

Light at the end of the nanotunnel for future catalysts

( Chalmers University of Technology) Using a new type of nanoreactor, researchers at Chalmers University of Technology, Sweden, have succeeded in mapping catalytic reactions on individual metallic nanoparticles. Their work could help improve chemical processes, and lead to better catalysts and more environmentally friendly chemical technology. The results are published in the journal Nature Communications.

Visualizing heat flow in bamboo could help design more energy-efficient and fire-safe buildings

( University of Cambridge) Modified natural materials will be an essential component of a sustainable future, but first a detailed understanding of their properties is needed. The way heat flows across bamboo cell walls has been mapped using advanced scanning thermal microscopy, providing a new understanding of how variations in thermal conductivity are linked to the bamboo's elegant structure. The findings, published in the journal Scientific Reports, will guide the development of more energy-efficient and fire-safe buildings, made from natural materials, in the future.

Stretchable, degradable semiconductors

( American Chemical Society) To seamlessly integrate electronics with the natural world, materials are needed that are both stretchable and degradable -- for example, flexible medical devices that conform to the surfaces of internal organs, but that dissolve and disappear when no longer needed. However, introducing these properties to electronics has been challenging. Now, researchers reporting in ACS Central Science have developed stretchable, degradable semiconductors that could someday find applications in health and environmental monitoring.

Deep learning expands study of nuclear waste remediation

( DOE/Lawrence Berkeley National Laboratory) A research collaboration between Berkeley Lab, Pacific Northwest National Laboratory, Brown University, and NVIDIA has achieved exaflop performance with a deep learning application used to model subsurface flow in the study of nuclear waste remediation.

Etalumis 'reverses' simulations to reveal new science

( DOE/Lawrence Berkeley National Laboratory) A multinational collaboration using computing resources at the National Energy Research Scientific Computing Center has developed the first probabilistic programming framework capable of controlling existing simulators and running at large-scale on HPC platforms.

How artificial intelligence can transform psychiatry

( University of Colorado at Boulder) Scientists have developed a new mobile app that categorizes mental health status based on speech patterns. It could be used as an adjunct for in-person therapy and to help monitor patients from afar. But, as the researchers note in a new paper, more must be done to earn public trust.

Engineers help with water under the bridge and other tough environmental decisions

( Michigan Technological University) From energy to water to food, civil engineering projects greatly impact natural resources. One engineer hopes that other engineers can step up to the challenge to help make decisions clearer, if not easier. Using a sustainability-based optimization algorithm, a Michigan Tech team examines biofuels, sea level rise, and other challenges.

Astronauts to test drive a lunar robot from the space station

( NASA/Johnson Space Center) Astronauts could one day remotely control Moon and Mars rovers from orbit. An upcoming test aboard the International Space Station could help make this a possibility.

New material points toward highly efficient solar cells

( Purdue University) A new type of material for next-generation solar cells eliminates the need to use lead, which has been a major roadblock for this technology.
