As a foundational species, giant kelp (Macrocystis pyrifera) is vital to the ecosystem of the temperate, shallow, nearshore waters where it grows. When the kelp flourishes, so do the communities that rely on the fast-growing species for food and shelter.
Terahertz radiation, between infrared and microwave radiation in the electromagnetic spectrum, possesses unique advantages for fundamental studies and practical applications. The ability to generate and manipulate broadband chiral terahertz waves is essential for applications in material imaging, terahertz sensing, and medical diagnosis. It can also open up new possibilities for nonlinear...
Forest-dependent people living across the Gran Chaco have been put on the map for the first time. As agribusiness expands into the dry forest on which they rely, the impact of that expansion on them has been difficult to document because their homesteads are dotted over 1 million km2. But now an international team of researchers has used high resolution satellite imagery to systematically identify...

Kellie Lynch, associate professor in the UTSA Department of Criminology and Criminal Justice is addressing the critical link between the COVID-19 pandemic and firearm-related abuse and the need for safety planning.
Whales use a combination of rapid echolocation adjustments and nimble brain responses to zero in on fast-moving prey, suggests a new study.
Cells can control their ability to move through the body by using a protein called fascin to control the stiffness of neighbouring cells, suggests a new study.
Meteorologists and emergency workers continue to contest the popular thinking that waiting out a tornado under an overpass is safe. According to the National Weather Service, doing so could actually increase the risk of death, in part because the wind from a tornado is thought to accelerate as it flows under the overpass, in what's known as the wind tunnel effect.
Scientists have used down-scaled laboratory models to show how sand dunes move through a landscape, revealing the conditions that determine whether they will pass through hurdles in their path -- like pipelines or walls -- or get stopped in their tracks.
An international team of scientists has identified a new connection between certain molecules produced by the microbiome and the function of a protein that impacts gut inflammation.
The next time you buy a new couch, you may not ever have to leave your old one to get a feel for the texture of the new material. Researchers are working to better define how the finger interacts with a device with the hope of aiding in the further development of technology that goes beyond sensing and reacting to your touch.
Water is a scarce commodity in many countries worldwide, but new cost-effective technology pioneered by researchers in Australia, Egypt and Saudi Arabia could ensure sustainable water supplies for decades to come.
Psychologists have created body-maps of the sensations which arise during hallucinations in people experiencing psychosis.
According to a study of couples in the Houston area before and after Hurricane Harvey, natural disasters can actually bring married couples closer together, at least temporarily. This surprised researchers because in previous studies looking at everyday stressors, couples typically experience 'stress spillover' in their relationships, which can decrease their satisfaction with their relationships....
Changing levels of the chemical dopamine, a chemical most associated with motivation, may help explain why stressful experiences during infancy can lead to lasting behavioral issues, a new study shows.
Accurate forecasting of epidemic scenarios is critical to implementing effective public health intervention policies. Researchers used dynamical stochastic modeling techniques to reveal that infection and recovery rate fluctuations play a critical role in determining peak times for epidemics. Using a susceptible-infected-recovered epidemic model that incorporates daily fluctuations on control...
Researchers outline how a robot could be taught to navigate through a maze by electrically stimulating a culture of brain nerve cells connected to the machine. These nerve cells were grown from living cells and acted as the physical reservoir for the computer to construct coherent signals. These findings suggest goal-directed behavior can be generated without any additional learning by sending...
Imagine a single policy, imposed on one industry, which would, if enforced consistently, stop fossil fuels causing global warming within a generation. The Carbon Takeback Obligation could do just that. It requires fossil fuel extractors and importers to dispose safely and permanently of a rising fraction of the CO2 they generate, with that fraction rising to 100% by the year of net-zero....
Common semiconductor materials for solar cells, such as silicon, must be grown via an expensive process to avoid defects within their crystal structure that affect functionality. But metal-halide perovskite semiconductors are emerging as a cheaper, alternative material class, with excellent and tunable functionality as well as easy processability.
Researchers have developed a tiny optical frequency comb, or microcomb, that uses two-mode squeezing to create unconditional entanglement between continuous optical fields. The miniature chip-based device lays the groundwork for mass production of deterministic quantum frequency combs that could be used for quantum computing, quantum metrology and quantum sensing.
Similar to grass stems, Lawrence Livermore National Laboratory (LLNL) scientists have created nanostrut-connected tube-in-tubes that enable stronger low-density structural materials.
