Using "Kerr solitons" to boost the power of transmission electron microscopes
When light goes through a material, it often behaves in unpredictable ways. This phenomenon is the subject of an entire field of study called "nonlinear optics," which is now integral to technological and scientific advances from laser development an.....»»
How magnetization direction can be controlled using strain in an interfacial multiferroic material
Controlling the direction of magnetization using low electric field is necessary for developing efficient spintronic devices. In spintronics, properties of an electron's spin or magnetic moment are used to store information. The electron spins can be.....»»
A colossal star erupts: Examining one of the largest stars in the Milky Way as it fades from view
Astronomers from Georgia State University's CHARA Array have captured the first close-up images of a massive star known as RW Cephei that recently experienced a strange fading event. The images are providing new clues about what's happening around th.....»»
Researchers discover important membrane transport mechanism in pathogenic bacteria
Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial membrane. Like a forklift, a soluble protein outside t.....»»
Q&A: Researchers highlight the potential for microrobots in diagnosing and treating infectious diseases
Biofilms—structured communities of microorganisms that create a protective matrix shielding them from external threats, including antibiotics—are responsible for about 80% of human infections and present a significant challenge in medical treatme.....»»

Using Berry phase monopole engineering for high-temperature spintronic devices
Spintronic devices are electronic devices that utilize the spin of electrons (an intrinsic form of angular momentum possessed by the electron) to achieve high-speed processing and low-cost data storage. In this regard, spin-transfer torque is a key p.....»»
Logging and climate change threaten montane birds
Researchers at the Indian Institute of Science (IISc) have studied the effects of forest logging and climate change on bird communities in tropical mountains, by examining over 10 years of data......»»
The accuracy of self-estimation in evaluating technology use
In a recent study examining the accuracy of self-estimation in evaluating technology use, researchers analyzed data from more than 300 iPhone users in China. The findings indicate a moderate correlation between self-reported usage and actual screen t.....»»
Progress in the investigation of ultrafast electron dynamics using short light pulses
When electrons move within a molecule or semiconductor, this occurs on unimaginably short time scales. A Swedish-German team, including Dr. Jan Vogelsang from the University of Oldenburg, has now made significant progress towards a better understandi.....»»
The surprisingly resourceful ways bacteria thrive in the human gut
The gut microbiome is so useful to human digestion and health that it is often called an extra digestive organ. This vast collection of bacteria and other microorganisms in the intestine helps us break down foods and produce nutrients or other metabo.....»»
The use of deep learning for phase recovery
Light, as an electromagnetic field, has two essential components: amplitude and phase. However, optical detectors, usually relying on photon-to-electron conversion (such as charge-coupled device sensors and the human eye), cannot capture the phase of.....»»
