How risky is travel in the US? It gets tricky. Despite a lot of research on the dangers of traffic injury and death, there's a lack of clarity on the role of the built environment (roadway designs and adjoining development) and its risk effects. Before we can know how risky a given built environment is, we have to know how many people are traveling there, and in many cases, for pedestrians and cyclists, this data is not available.
A new study is the first to examine the relationship between post-traumatic stress disorder (PTSD) and dozens of infection types in a nationwide cohort. Researchers found that PTSD affects infection risks for men and women differently, having, for example, more of an effect on a woman's risk of urinary tract infection and a man's risk of skin infection.
Recent archaeological investigations in the Tollense Valley by a research team has unearthed a collection of 31 unusual objects. Researchers believe this is the equipment of a Bronze Age warrior who died on the battlefield 3,300 years ago. This unique find was discovered by a diving team. It may have been protected in the river from the looting after the fighting.
Immigrant parents worry their children will struggle with reading and fret that as non-English speakers, they can't help. A new study shows that's simply not true. Reading to a young child in any language will likely help them learn to read in English.
Tiny magnetic vortices known as skyrmions form in certain magnetic materials, such as Cu2OSeO3. These skyrmions can be controlled by low-level electrical currents -- which could facilitate more energy-efficient data processing. Now a team has succeeded in developing a new technique at the VEKMAG station of BESSY II for precisely measuring these vortices and observing their three different predicted characteristic oscillation modes (Eigen modes).
Calcium-based batteries promise to reach a high energy density at low manufacturing costs. This lab-scale technology has the potential for replacing lithium-ion technology in future energy storage systems. Using the electrolytes available, however, it has been impossible so far to charge calcium batteries at room temperature. Researchers of Karlsruhe Institute of Technology (KIT ) now present a promising electrolyte class, with which this will be possible.
The human brain is about three times the size of the brains of great apes. This has to do, among other things, with the evolution of novel brain structures that enabled complex behaviors such as language and tool production. A study by anthropologists now shows that changes in the brain occurred independent of evolutionary rearrangements of the braincase.
An oscillation assisted digital light processing (DLP) based 3D printing approach is developed to enable ultrafast fabrication of microlens arrays with optically smooth surface (1 nm surface roughness) via a single 1-3 seconds exposure of grayscale UV light.
Using a range of theoretical and simulation approaches, physicists have shown that liquids in contact with substrates can exhibit a finite number of classes of behavior and identify the important new ones.
A phenomenon that has previously been seen when researchers simulate the properties of planet cores at extreme pressures has now also been observed in pure titanium at atmospheric pressure. Chains of atoms dash around at lightning speeds inside the solid material.
According to a new study published in the journal Scientific Reports, when it comes to being willing to explore more efficient options to solving a problem, capuchin monkeys and rhesus macaques exhibit more cognitive flexibility than our own species. As humans, we live in complex environments and inevitably have to rely on imperfect information when we [...]
An international team of researchers has published a new study examining a 430,000-year-old cranium of a human ancestor that was previously described as deaf, representing the oldest case of deafness in human prehistory.
Tungsten diselenide emits light with very special properties. Nobody could tell why -- but now, scientists have solved the riddle: a combination of atomic defects in the material and microscopic distortion is responsible for the remarkable effect.
Babies seek to understand the world around them and learn many new things every day. Unexpected events -- for example when a ball falls through a table -- provide researchers with the unique opportunity to understand infants' learning processes. What happens in their brains as they learn and integrate new information?
Forests help protect the climate. Reforestation can decisively contribute to mitigating global warming according to the Paris Agreement. Based on simulations, researchers have studied the conditions that should be fulfilled in Europe for this. According to the study, sufficient increase in forest areas requires a transformation of the food system and in particular, the reduction of meat consumption.
