Unique quantum material could enable ultra-powerful, compact computers
Optical imaging and characterization of weakly scattering phase objects, such as isolated cells, bacteria and thin tissue sections frequently used in biological research and medical applications, have been of significant interest for decades. Due to their optical properties, when these 'phase objects' are illuminated with a light source, the amount of scattered light is usually much less than the...
Where do "Hawaiian box jellies" come from?
Information in computers is transmitted through semiconductors by the movement of electrons and stored in the direction of the electron spin in magnetic materials. To shrink devices while improving their performance—a goal of an emerging field called spin-electronics ("spintronics")—researchers are searching for unique materials that combine both quantum properties. Writing in Nature...
Unraveling a perplexing explosive process that occurs throughout the universe
An insightful cross-disciplinary team of University of Hawai'i (UH) at Mānoa researchers, working for over a decade, published a study recently revealing that a key number of hours of darkness during the lunar cycle triggers mature "Hawaiian box jellyfish" (Alatina alata) to swim to leeward O'ahu shores to spawn.
Geothermal drilling successes offer potential gain for petroleum industry
Mysterious fast radio bursts release as much energy in one second as the Sun pours out in a year and are among the most puzzling phenomena in the universe. Now researchers at Princeton University, the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and the SLAC National Accelerator Laboratory have simulated and proposed a cost-effective experiment to produce and...
Researchers demonstrate organic crystals can serve as energy converters for emerging technologies
Texas A&M University researchers Dr. Sam Noynaert and Fred Dupriest recently presented results from a geothermal project that drastically reduced well-completion times and drill bit changeouts to an audience of mostly petroleum drillers. The Department of Energy (DOE) funded the project, which improves geothermal drilling practices with physics-based instruction and oil and gas techniques to lower...
Key Iraq irrigation reservoir close to drying out
New research by a team of researchers at the NYU Abu Dhabi (NYUAD) Smart Materials Lab published today in the journal Nature Communications demonstrates that organic crystals, a new class of smart engineering materials, can serve as efficient and sustainable energy conversion materials for advanced technologies such as robotics and electronics.
Light pollution can disorient monarch butterflies
Iraq's Lake Hamrin, a once-vast reservoir northeast of Baghdad that is the sole source of water for irrigation across Diyala province, has nearly dried out, a senior official said Friday.
Are Republicans and Democrats driven by hatred of one another? Less than you think
Besides planting milkweed in the garden, people interested in helping monarch butterflies might want to turn off the porch light.
Scientists explain why meridional heat transport is underestimated
When it comes to attitudes and behaviors among members of American political parties, the conventional wisdom is that hate is stronger than love.
The Atlantic Meridional Overturning Circulation (AMOC) is a phenomenon responsible for transporting ocean heat northward through the Atlantic Ocean. This process significantly influences the Arctic and North Atlantic oceanic climate and the Eurasian continental climate. The corresponding cross-equatorial northward heat transport also determines the location of the Intertropical Convergence Zone...
