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 Under extreme impacts, metals get stronger when heated, study finds
(via sciencedaily.com)
Original source 
Scientists have discovered that when metal is struck by an object moving at a super high velocity, the heat makes the metal stronger. The finding could lead to new approaches to designing materials for extreme environments, such as shields that protect spacecraft or equipment for high-speed manufacturing.
Published New AI accurately predicts fly behavior
(via sciencedaily.com)
Original source 
Researchers trained an AI model to accurately predict male fruit flies' courtship behavior in response to any sight of a female. This breakthrough offers new insight into how the brain processes visual data and may someday pave the way for artificial vision technology.
Published Strings that can vibrate forever (kind of)
(via sciencedaily.com)
Original source 
Researchers have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object -- approaching what is currently only achievable near absolute zero temperatures. Their study pushes the edge of nanotechnology and machine learning to make some of the world's most sensitive mechanical sensors.
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 Excavation reveals 'major' ancient migration to Timor Island
(via sciencedaily.com)
Original source 
The discovery of thousands of stone artefacts and animal bones in a deep cave in Timor Island has led archaeologists to reassess the route that early humans took to reach Australia. Researchers dated and analysed the artefacts and sediment at the Laili rock shelter in central-north Timor-Leste, north of Australia, to pinpoint the arrival of the colonists.
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 Roots are a key to drought-tolerant maize
(via sciencedaily.com)
Original source 
Maize can grow successfully in very different local conditions. An international study has now demonstrated the important role of the plant root system. The researchers analyzed more than 9,000 varieties in the study and were able to show that their roots varied considerably -- depending on how dry the location is where each variety was cultivated. They were also able to identify an important gene that plays a role in the plant's ability to adapt. This gene could be the key to developing varieties of maize that cope better with climate change.
Published Cuddled cows who work as therapy animals showed a strong preference for women compared to men, study finds
(via sciencedaily.com)
Original source 
A new study reveals that cows who are cuddled as therapy animals showed a strong preference for interactions with women when compared to men. In turn, the research, which opens a new era on whether some therapies may be initially stronger based upon gender and not procedure, highlighted that the women also reported greater attachment behaviors towards the steers.
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 Milk samples from the 1940s shed new light on antibiotic resistance
(via sciencedaily.com)
Original source 
Researchers started with 50 samples collected from 1941 to 1947, and they found that the samples contained seven different Streptococcus species, including two subspecies of S. dysgalactiae. Interestingly, the researchers found some of the samples were resistant to the antibiotic tetracycline and did not carry antibiotic resistance genes typically seen in today's antibiotic-resistant bacterial strains. Since these samples were collected prior to the antibiotic era, the results add to a growing body of literature showing that antibiotic resistance occurred naturally before humans discovered and began to use antibiotics.
Published Naturally occurring substance in pomegranates can improve treatment of Alzheimer's disease
(via sciencedaily.com)
Original source 
A substance naturally occurring in i.a. pomegranates, strawberries and walnuts can improve memory and treatment of Alzheimer's disease, a new study concludes.
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 Streamlined microcomb design provides control with the flip of a switch
(via sciencedaily.com)
Original source 
Researchers describe new microcomb lasers they have developed that overcome previous limitations and feature a simple design that could open the door to a broad range of uses.
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.
Published Sewage overflows linked to increase in gastrointestinal illnesses
(via sciencedaily.com)
Original source 
A new study has found that residents living in the downstream communities that border the Merrimack River are at a substantially increased risk of developing acute gastrointestinal illnesses (AGI) in the four days following large-volume combined sewer overflows (CSOs).
Published Study finds widespread 'cell cannibalism,' related phenomena across tree of life
(via sciencedaily.com)
Original source 
Researchers describe cell-in-cell phenomena in which one cell engulfs and sometimes consumes another. The study shows that cases of this behavior, including cell cannibalism, are widespread across the tree of life. The findings challenge the common perception that cell-in-cell events are largely restricted to cancer cells. Rather, these events appear to be common across diverse organisms, from single-celled amoebas to complex multicellular animals.
