The new instrument allows heat to temporarily flow from cold region to hot region without using any external energy. The process occurs through a series of quasi-equilibrium states, and completely obeys the second law of thermodynamics. What...
Researchers reveal personality features that predict the rhythm and nature of human sleep. Neuroticism and conscientiousness are found to be highly associated with sleep quality. Sleep is a crucial part of our daily lives. This naturally recurring...
A new class of material exhibits superconductivity at -23°C. The this is the new record for the highest-temperature superconductor, a jump of 50°C compared to the previous record. Until the late 1980s, superconductivity was thought to be a low...
Researchers develop a new technique to quickly measure common stress hormones using saliva, urine, blood, and sweat. Although the method is simple and inexpensive, it is not going to replace the comprehensive blood test done in a laboratory. ...
Neurobiologists describe a unique case of an amacrine cell called CT1 in a fruit fly. CT1 connects to approximately 1,400 regions in the fly brain and each cell area functions as a separate neuron. A computer simulation shows that CT1 reaches...
The smallest pixel ever created can be used to build massive screen, large enough to cover whole buildings. These pixels are a million times smaller than those in modern cell phones. In recent decades, plasmonic metasurfaces have emerged as a...
Researchers propose a new method (derived from classical physics) to predict how economies respond to major disturbances. It outperforms all existing econometric forecasting systems. Understanding economies in times of crises is one of the most...
New method enables fast 3D reconstructions of nanoscale objects. It works by taking two images of an object from two different locations and combining them to form a spatial image. There exist countless object in nature that has complex 3D...
Physicists develop a sophisticated setup capable of generating ultra-high controllable magnetic. They were able to generate a magnetic field of 1200 Tesla using electromagnetic flux compression. To measure the field strength, they used...
Researchers develop a new kind of biomaterial using artificial DNA as its base. It has all lifelike properties, including metabolism and the ability to self-assemble and organize. All living organisms maintain themselves by generating new cells...
Some unusual bacteria conduct electricity through a structure never observed before. Researchers use cryo-electron microscopy to identify the shape and composition of that structure in bacteria called Geobacter sulfurreducens. The findings can be...
Researchers image vibrational modes of molecules that were previously observed only in computer simulations. They used Tip-Enhanced Raman Spectroscopy to take snapshots of vibrating molecules. Standard optical microscopy can only image up to a few...
