As the global population ages, smart homes are often touted as the ultimate solution for independent living. However, a new study has been published JMIR aging, JMIR Publications’ leading Q1 journal suggests technology developers and policy makers may be missing the point by treating older adults as a monolithic group. The study, entitled “Segmentation of the needs and smart home readiness of older adults by housing-based lifestyle in Spain: a survey study”, identifies distinct lifestyle segments that determine whether older adults are likely to accept or reject smart home innovations. go beyond age The study, led by Zhiyong Yu, Angelica…

Public concern about air pollution has traditionally focused on chemical pollutants such as vehicle exhaust and industrial emissions found in particulate matter (PM2.5). However, researchers at the Hong Kong Polytechnic University (PolyU) have discovered that seemingly insignificant microbial components present in the air, such as bacteria, fungi, viruses and cell debris, pose a long-overlooked health hazard. The study revealed that bacterial endotoxins can cause an inflammatory response in the human respiratory system in almost 20% of cases, despite accounting for less than one millionth of the total mass of PM2.5. The researchers also detected drug-resistant bacteria in urban air, further…

Malaria remains a threat to young children in refugee settlements, where displacement, temporary housing, and limited access to health care reduce the effectiveness of traditional prevention measures. There are an estimated 35 million refugees in Africa alone, more than 80% of whom are women and children. New arrivals lack permanent shelter and cannot reliably use mosquito nets, making infants and young children more susceptible to mosquito bites. Ross Boyce, MD, MS, a researcher in the Institute of Global Health and Infectious Diseases at the UNC School of Medicine, will lead a three-year study in collaboration with partners at Uganda’s Mbarara…

The human gut is home to a complex ecosystem of trillions of microorganisms (microbiome) that influence digestion, immune system, and metabolism. Using a ‘reverse ecology’ analytical approach, a research team led by the University of Vienna demonstrated that many known species of gut bacteria are composed of several evolutionarily distinct groups that have adapted to different conditions in the gut. Some of these populations are associated with older age, chronic inflammatory bowel disease, colorectal cancer, and type 2 diabetes. The results of this research are currently nature In the future, the search for biomarkers will improve and may allow more…

People who eat more ultra-processed foods (UPF) have a higher risk of cardiovascular disease and death, according to a report published in . european heart journal Today (Thursday). This report was prepared by a group of cardiology experts from across Europe and compiles the results of all research on UPF and cardiovascular disease published to date. This highlights the risks of death from obesity, diabetes, hypertension, chronic kidney disease, and cardiovascular disease that are currently associated with consuming large amounts of UPF. The report’s authors urge doctors to talk to their patients about how much UPF they are taking and…

Understanding how surfaces grow has long been one of the most important challenges in physics. In 1986, researchers introduced the Kardar-Parisi-Zhang (KPZ) equation, a theory designed to explain growth across a wide range of systems. Over time, this framework has been applied to everything from crystal formation and population dynamics to flame surfaces and even machine learning. This idea is simple but powerful. Quite different systems may grow to follow the same underlying rules. Now, scientists at the University of Würzburg have taken a major step forward. After previously being confirmed in a one-dimensional system in 2022, the team achieved…

Cumberland, British Columbia grew out of coal mining. For decades, this industry defined daily life, employed thousands of workers, and shipped millions of tons of coal around the world. When the mine operations closed after some 80 years, more than just an empty tunnel was left behind. The closures also created persistent economic disparities in communities. Today, the underground networks that once supported industry could help us achieve a cleaner future. The University of Cumberland is researching how abandoned shafts and tunnels can be used as a new energy source through a partnership with the University of Victoria-led Accelerated Community…

Scientists in Sweden have developed a more reliable way to create insulin-producing cells from human stem cells, giving new momentum to efforts to treat type 1 diabetes. This study stem cell reportshowing that these lab-grown cells can effectively control blood sugar and even reverse diabetes in mice in tests. Type 1 diabetes occurs when the immune system attacks and destroys insulin-producing cells in the pancreas. Without insulin, the body cannot properly absorb glucose from the bloodstream, leading to dangerous blood sugar levels. Replacing these lost cells has long been considered a promising solution, but previous attempts to grow cells from…

Blue Origin’s Lunar Module MK1, also known as Endurance, is an unmanned cargo spacecraft designed to test critical technologies for future lunar missions. The vehicle is part of a commercial demonstration effort aimed at enhancing the capabilities of human landing systems in NASA’s Artemis program. This project focuses on the growing public-private cooperation model. Blue Origin conducted the testing through a reimbursable Space Act contract with NASA and leveraged the agency’s facilities and expertise to accelerate development. Testing critical lunar landing technology Endurance is being built to validate several critical systems needed for operations on the lunar surface. These include…

When humans estimate another person’s body size, it is not necessary to observe the whole body to make an accurate estimate. New research has revealed that people rely heavily on a specific combination of features in their lower bodies, especially around their thighs. This research recently BMC biology. Understanding how people perceive body dimensions has practical implications for health and psychology. Inaccurate judgments about one’s own and others’ body image play a central role in body image disturbances. Conditions like anorexia nervosa are often accompanied by a distorted visual perception of body proportions. Researchers want to understand the exact visual…
