Physicists have invented a new radar prototype that utilizes quantum entanglement as a method of object detection. This successful integration of quantum mechanics into our everyday devices could significantly impact the biomedical and security industries.
A new study has identified thousands of incidents of previously rare or unprecedented extreme heat/humidity combinations in parts of Asia, Africa, Australia, South America and North America, including in the U.S. Gulf Coast region.
Researchers have found that flies sleep more when they can't fly, possibly because sleeping helps them adapt to a challenging new situation.
Inspired by the biomechanics of cheetahs, researchers have developed a new type of soft robot that is capable of moving more quickly on solid surfaces or in the water than previous generations of soft robots. The new soft robotics are also capable of grabbing objects delicately -- or with sufficient strength to lift heavy objects.
As interest in the application of plasma medicine -- the use of low-temperature plasma (LTP) created by an electrical discharge to address medical problems -- continues to grow, so does the need for research advancements proving its capabilities and potential impacts on the health care industry. Across the world, many research groups are investigating plasma medicine for applications including...
A research team has good news for patients with copper-deficiency disorders, especially young children diagnosed with Menkes disease.
New research describes a new model for how the brain interprets patterns in complex networks. They found that the ability to detect patterns stems in part from the brain's desire to represent things in the simplest way possible and that the brain is constantly weighing the pressures of complexity and simplicity when making decisions.
Researchers know the secret to geckos' ability to walk on the ceiling: their hairy toes. But how do they use their five toes per foot to adjust to gravity when running horizontally along walls. Biologists have now used high-speed cameras to record how geckos orient their toes with shifting weight, especially when encountering slippery or rough patches, and found a remarkable ability to adjust toe...
A new study has found that stroke evaluations fell by nearly 40 percent during a period of the COVID-19 pandemic, suggesting that many stroke patients are not seeking potentially life-saving medical treatment.
A new global simulation model offers the first long-term look at how urbanization -- the growth of cities and towns -- will unfold in the coming decades. The research team projects the total amount of urban areas on Earth can grow anywhere from 1.8 to 5.9-fold by 2100, building approximately 618,000 square miles.
A recent study has described new states that can be found in super-cold atom experiments, which could have applications for quantum technology.
Scientists have developed a green way to create chitin, by using two forms of food waste - prawn shells and discarded fruit - and fermenting them.
Regular processes in the environment improve our eyesight.
Hematopoietic stem cells from a healthy donor can help patients suffering from acute leukemia. However, the side effects of therapies are often severe. Researchers have now shown how human healthy and cancerous hematopoietic stem cells can be more selectively eliminated using immunotherapy instead of chemotherapy in mice. The aim is to test the new immunotherapy in humans as soon as possible.
Scientists have successfully developed a new technique to reliably grow crystals of organic soluble molecules from nanoscale droplets, unlocking the potential of accelerated new drug development.
A protein shredder that occurs in cell membranes of brain cells apparently also indirectly regulates the fat metabolism. The shredder, known as gamma-secretase, is considered a possible target for drugs against cancer and Alzheimer's disease. However, the results suggest that such agents may have long-range effects that need to be watched closely.
The Monte Conca cave system in Sicily is showing signs of being altered by pollution from above.
The brain has a powerful ability to remember and connect events separated in time. And now, in a new study in mice, scientists have shed light on how the brain can form such enduring links.
In many fish species body size plays an important role in sexual selection. Large individuals are preferred mating partners because they can enhance offspring survival by providing better quality resources than small individuals. While large females and males are often favored by sexual selection, fishing targets and removes these reproductively superior individuals.
Evidence continues to mount that the Neanderthals, who lived in Europe and Asia until about 40,000 years ago, were more sophisticated people than once thought. A new study shows that Neanderthals chose to use bones from specific animals to make a tool for specific purpose: working hides into leather.
A team has produced a family of dendrimers that form single-crystals and can harvest non-polarized light and transform it into polarized emission. The dendrimer crystals are both optically and mechanically stable to optical pumping, making them the first example of a crystalline material combining dendrimer properties and laser performance. The crystals are expected to have numerous applications...
A new study finds that temperature and latitude do not appear to be associated with the spread of coronavirus disease 2019 (COVID-19), but school closures and other public health measures are having a positive effect.
Millions of people around the world use acid suppressants called proton pump inhibitors for conditions like heartburn, gastritis and stomach ulcers. Researchers at Karolinska Institutet in Sweden now report that how the long-term use of these drugs could increase the risk of developing dementia. Their results are published in the journal Alzheimer's & Dementia.
Some plants, like soybean, are known to possess an innate defense machinery that helps them develop resistance against insects trying to feed on them. However, exactly how these plants recognize signals from insects has been unknown until now. Scientists have now uncovered the cellular pathway that helps these plants to sense danger signals and elicit a response, opening doors to a myriad of...
