Researchers demonstrate enhanced radiative heat transfer for nanodevices

Researchers demonstrate enhanced radiative heat transfer for nanodevices

Researchers from Japan have been working hard to keep their cool—or at least—keep their nanodevices from overheating. By adding a tiny coating of silicon dioxide to micro-sized silicon structures, they were able to show a significant increase in the rate of heat dissipated. This work may lead to smaller and cheaper electronic devices that can pack in more microcircuits.

Researchers discover optimal conditions for mass production of ultraviolet holograms

Researchers discover optimal conditions for mass production of ultraviolet holograms

Researchers have delved into the composition of nanocomposites for ultraviolet metasurface fabrication and determined the ideal printing material for crafting them. Their findings are featured in the journal Microsystems & Nanoengineering on April 22.

For sustainable aviation fuel, researchers engineer a promising microorganism for precursor production

For sustainable aviation fuel, researchers engineer a promising microorganism for precursor production

Sustainable aviation fuels made from renewable sources of carbon could reduce carbon dioxide emissions and help to mitigate climate change. Isoprenol is a chemical involved in the production of a jet biofuel blendstock called 1,4-dimethylcyclooctane (DMCO). Blendstocks are chemicals that are combined with other chemicals to create fuel. Researchers have produced isoprenol in several microbial hosts.

Study finds liberals and conservatives differ on climate change beliefs—but are relatively united in taking action

Study finds liberals and conservatives differ on climate change beliefs—but are relatively united in taking action

The division between liberals and conservatives on both climate-change beliefs and related policy support is long-standing. However, the results of a newly released global experiment show that despite these differences, the two camps actually align when it comes to taking certain actions to combat climate change.

Scientists demonstrate the potential of electron spin to transmit quantum information

Scientists demonstrate the potential of electron spin to transmit quantum information

The spin of the electron is nature's perfect quantum bit, capable of extending the range of information storage beyond "one" or "zero." Exploiting the electron's spin degree of freedom (possible spin states) is a central goal of quantum information science.

Biogeographical evidence shows trickster animal folklore is limited by environmental factors

Biogeographical evidence shows trickster animal folklore is limited by environmental factors

Humans have the capacity to imagine civilizations and creatures that have never existed, and our language reflects that ability. It would therefore be understandable if the stories we tell ourselves stretched beyond the bounds of local ecology. However, research has shown that many cultural artifacts and ideas are strongly affected by environmental factors.

Should we fight climate change by re-engineering life itself?

Should we fight climate change by re-engineering life itself?

Life has transformed our world over billions of years, turning a dead rock into the lush, fertile planet we know today. But human activity is currently transforming Earth again, this time by releasing greenhouse gases that are driving dramatic changes in our climate.

Laser printing on fallen tree leaves produces sensors for medical and laboratory use

Laser printing on fallen tree leaves produces sensors for medical and laboratory use

Fabrication of sensors by 3D printing combines speed, freedom of design, and the possibility of using waste as a substrate. Various results have been obtained in a circular economy mode, whereby residues usually thrown away are instead used as low-cost resources.

Improved wildfire smoke model identifies areas for public health intervention

Improved wildfire smoke model identifies areas for public health intervention

The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to a team led by Penn State scientists.

NASA images help explain eating habits of massive black hole

NASA images help explain eating habits of massive black hole

In images from NASA's retired Spitzer Space Telescope, streams of dust thousands of light-years long flow toward the supermassive black hole at the heart of the Andromeda galaxy. It turns out these streams can help explain how black holes billions of times the mass of our sun satiate their big appetites but remain "quiet" eaters.
