New Alzheimer’s research from UVA Health suggests that enhanced light sensitivity may contribute to “sundowning” – the worsening of symptoms late in the day – and spur sleep disruptions thought to contribute to the disease’s progression.  The new insights into the disruptions of the biological clock seen in Alzheimer’s could have important potential both for the development of treatments and for symptom management, the researchers say. For example, caregivers often struggle with the erratic sleep patterns caused by Alzheimer’s ...

Introduced in 2004, high-entropy alloys (HEAs) are alloys composed of multiple principal elements in nearly equiatomic proportions. Their unique chemical composition results in a high degree of chemical disorder, i.e. entropy, and produces remarkable properties such as high strength, ductility, and strong wear-and-tear resistance even at high temperatures. Scientists have dedicated a significant amount of attention to developing novel HEAs to help improve the performance of various electrocatalyst materials. Because they are made up of differing constituent elements, HEAs' atomic-level surface designs can be complex. But unravelling this complexity is crucial, since the surface ...

San Diego, CA - The NEC Society and Cincinnati Children’s have teamed up to present the NEC Symposium, the only conference in North America dedicated to understanding and preventing necrotizing enterocolitis (NEC). NEC is a devastating intestinal disease that affects medically fragile infants in their first weeks and months of life. Every year in the United States, thousands of babies are diagnosed with NEC and at least one baby dies from NEC every day. The NEC Symposium will transform the NEC Research ...

North Carolina State University researchers recently found that a program designed to get Girl Scouts involved in citizen science – programs where members of the public can participate in real scientific research – not only taught girls about the process of science, but also motivated them to tackle scientific or environmental problems in their communities. The findings demonstrate the impacts citizen science projects can have on their participants and offer lessons for other organizations on how to structure STEM-focused learning opportunities using citizen science. “We’ve found that after participating ...

Six structures exhibited by the rotating sodium ion pump were reconstructed in 3D using cryo-electron microscopy. This analysis revealed that (1) the rotor exhibits non-uniform rotation behavior due to partial structural interference with the stator component, and (2) the rotor interacts with one edge of the large ion transport ring causing it to rotate. The study showed a unique molecular mechanism of the rotary sodium ion pump.   The results will be published on July 28 in Communications Biology.   “In previous single-molecule imaging ...

Resilient corals, often referred to as ‘super corals’, have recently been seen as potential saviours in the face of climate change and its detrimental effects on coral reefs. Now, a team of scientists from the University of Technology Sydney (UTS) and the University of Haifa, Israel is working to better understand these corals in order to develop strategies to protect fragile ecosystems such as the Great Barrier Reef. UTS scientist Dr Emma Camp, co-lead researcher on the study recently published in the journal Nature Communications, says the findings have significant implications ...

Infants who nap a lot have smaller vocabularies and poorer cognitive skills – according to new research from the University of East Anglia. Parents the world over are prone to worry about their children getting either too little or too much sleep. But a new study published today reveals that some children are more efficient at consolidating information during sleep, so they nap less frequently. Meanwhile others, usually those with fewer words and poorer cognitive skills, need to nap more frequently. The research team say that reducing naps for these children will not improve brain development, ...

Though it’s just as likely to be worn while lounging on the couch as in the gym, a large driver of activewear’s popularity among women is its association with a dynamic lifestyle, positive wellbeing and overall good health.    However, two new Edith Cowan University (ECU) studies suggest online shopping for activewear may in fact be harmful to women’s body image.    Sales of “Athleisure” — a hybrid style of athletic clothing typically worn as everyday wear — have risen rapidly following ...

This soft robotic gripper is not only 3D printed in one print, it also doesn’t need any electronics to work.  The device was developed by a team of roboticists at the University of California San Diego, in collaboration with researchers at the BASF corporation, who detailed their work in a recent issue of Science Robotics.  The researchers wanted to design a soft gripper that would be ready to use right as it comes off the 3D printer, equipped with built in gravity and touch sensors. As a result, the gripper can pick up, hold, and release objects. No such gripper existed before this work.  “We ...

Opioids remain the most potent and effective pain relievers in medicine, but they’re also among the most addictive drugs that can halt a person’s ability to breathe during an overdose — which can be deadly. Researchers have been racing to develop safer pain reliever drugs that target a specific opioid receptor, called the kappa opioid receptor, that is only found in the central nervous system and not elsewhere in the body, like other opioid receptors. Previous research suggests that such drugs may not lead to addiction or death due to overdose, but ...

Researchers at NYU College of Dentistry’s Pain Research Center have developed a gene therapy that treats chronic pain by indirectly regulating a specific sodium ion channel, according to a new study published in the Proceedings of the National Academy of Sciences (PNAS).   The innovative therapy, tested in cells and animals, is made possible by the discovery of the precise region where a regulatory protein binds to the NaV1.7 sodium ion channel to control its activity.   “Our study represents a major step forward in understanding the underlying biology of the NaV1.7 sodium ion channel, which can be harnessed to provide relief from chronic pain,” said Rajesh ...

At first glance, the hexagonal cells build by honey bees and social wasps may seem similar, but they are significantly different. Honey bees build using wax, whereas wasps use paper. Honey bees build their double-sided combs vertically, whereas wasps build single-sided comb horizontally (i.e., the opening of each cell faces downward). Indeed, the hexagonal cells built by these two groups have independent evolutionary origins. Just like sharks and whales have similar body plans due to their watery environment, bees and wasps build hexagonal cells because the shape maximizes strength and storage area, while minimizing building materials. But what happens when perfectly ...

During the COVID-19 pandemic, governments changed rules and procedures related to Medicaid enrollment. These changes decreased many of the burdens eligible people face when signing up for programs and contributed to a 30 percent increase in Medicaid enrollment. However, the end of public health emergency declarations brings an end to these pandemic policies, which many fear could lead to eligible people losing public health insurance simply because they are unable to fulfill administrative requirements such as accurately filling out and submitting forms, renewing their enrollment ...
