Published Effectiveness of GBGI infrastructure in mitigating urban heat, proposing nine-stage framework for development of a sustainable city
(via sciencedaily.com) Original source Primarily due to the impact of urbanisation and global warming, urban heatwaves have become a challenging issue worldwide, with Hong Kong persistently experiencing record-breaking high-temperature days. Mitigating urban heat through green and blue infrastructures is essential for creating a sustainable environment. Researchers have conducted a study on the effectiveness of green interventions in cooling urban heat across various regions that can assist policymakers in prioritizing effective interventions to develop sustainable cities.
Published Sexual parasitism helped anglerfish invade the deep sea during a time of global warming
(via sciencedaily.com) Original source Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.
Published Rising temperatures will significantly reduce streamflow in the upper Colorado river basin as groundwater levels fall
(via sciencedaily.com) Original source The Colorado River makes life possible in many Western cities and supports agriculture that sustains people throughout the country. Most of the river's water begins as snowmelt from the mountainous watersheds of Colorado, Utah, and Wyoming, and a warming climate will drastically reduce these streamflows, new research finds.
Published Wearable devices get signal boost from innovative material
(via sciencedaily.com) Original source An international team have developed a new material that moves like skin while preserving signal strength in electronics. The technology could enable the development of next-generation wearable devices with continuous, consistent wireless and battery-free functionality.
Published Wearable ultrasound patch enables continuous, non-invasive monitoring of cerebral blood flow
(via sciencedaily.com) Original source Engineers have developed a wearable ultrasound patch that can offer continuous, non-invasive monitoring of blood flow in the brain. The soft and stretchy patch can be comfortably worn on the temple to provide three-dimensional data on cerebral blood flow--a first in wearable technology.
Published Scientists learn how to control muscles with light
(via sciencedaily.com) Original source Researchers developed a way to help people with amputation or paralysis regain limb control. Their optogenetic technique could offer more precise control over muscle contraction, along with a dramatic decrease in muscle fatigue.
Published Chemist developing method to recycle more plastics
(via sciencedaily.com) Original source To improve recycling rates a professor is working on new ways to separate and recycle mixed plastics.
Published Researchers design new metal-free porous framework materials
(via sciencedaily.com) Original source Researchers have used computational design methods to develop non-metal organic porous framework materials, with potential applications in areas such as catalysis, water capture or hydrogen storage.
Published How the 'home' environment influences microbial interactions
(via sciencedaily.com) Original source A new study shows that real-world ocean conditions make a huge difference in how viral infection affects host bacteria. The findings indicate it is very important to study cells and virocells under nutrient conditions that more closely resemble what they encounter in nature.
Published Cement recycling method could help solve one of the world's biggest climate challenges
(via sciencedaily.com) Original source Researchers have developed a method to produce very low emission concrete at scale -- an innovation that could be transformative in the transition to net zero. The method, which the researchers say is 'an absolute miracle', uses the electrically-powered arc furnaces used for steel recycling to simultaneously recycle cement, the carbon-hungry component of concrete.
Published Adhesive coatings can prevent scarring around medical implants
(via sciencedaily.com) Original source Engineers have found a way to eliminate the buildup of scar tissue around implantable devices, by coating them with a hydrogel adhesive. The material binds the device to tissue and prevents the immune system from attacking the device.
Published Promethium bound: Rare earth element's secrets exposed
(via sciencedaily.com) Original source Scientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel.
Published Smoke covered 70% of California during biggest wildfire years
(via sciencedaily.com) Original source As much as 70 percent of California was covered by wildfire smoke during parts of 2020 and 2021, according to a new study.
Published Extreme temperatures may increase risk of stroke mortality, especially in low-income countries
(via sciencedaily.com) Original source Extreme heat and extreme cold are both associated with increased risks of death from ischemic and hemorrhagic stroke, according to a new study. The researchers found that the link between extreme temperatures and stroke mortality was stronger in low-income countries than in high-income countries.
Published 'Fossilizing' cracks in infrastructure creates sealing that can even survive earthquakes
(via sciencedaily.com) Original source In a new study, a team of researchers used research on fossilizing techniques to create a new method for sealing cracks and fractures in rocks and bedrock using a 'concretion-forming resin'. This innovative technique has applications in a wide range of industries, from tunnel construction to long-term underground storage of hazardous materials.
Published New polystyrene recycling process could be world's first to be both economical and energy-efficient
(via sciencedaily.com) Original source Engineers have modeled a new way to recycle polystyrene that could become the first viable way of making the material reusable.
Published Scientists develop new battery-free lactic acid sensor
(via sciencedaily.com) Original source Scientists have created a new type of chemosensor (demonstrated for lactic acid sensing) which functions with electricity but without the need for reference electrodes or battery power.
Published Flexible film senses nearby movements -- featured in blink-tracking glasses
(via sciencedaily.com) Original source I'm not touching you! When another person's finger hovers over your skin, you may get the sense that they're touching you, feeling not necessarily contact, but their proximity. Similarly, researchers have designed a soft, flexible film that senses the presence of nearby objects without physically touching them. The study features the new sensor technology to detect eyelash proximity in blink-tracking glasses.
Published New insights into the degradation dynamics of organic material in the seafloor
(via sciencedaily.com) Original source Many processes in the deep sea are not yet well understood, and the role of microbial communities in particular is often a big unknown. This includes, for example, how organic material that sinks from the water surface to the ocean floor is metabolised -- an important building block for a better understanding of the global carbon cycle.
Published Ethylene from CO2: Building-kit catalyst
(via sciencedaily.com) Original source Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary chemical raw material, from CO2. Nitrogen atoms with a particular electron configuration play a critical role for the catalyst.
