Published Escaped GMO canola plants persist long-term, but may be losing their extra genes
(via sciencedaily.com)
Original source 
Populations of canola plants genetically engineered to be resistant to herbicides can survive outside of farms, but may be gradually losing their engineered genes, reports a new study.
Published Community science volunteers can set scientific world abuzz with new bumble bee sightings
(via sciencedaily.com)
Original source 
Community science volunteers -- laypeople with an interest in bees and conservation -- significantly contribute to the scientific knowledge of native bumble bees across Canada and the United States. It's buzz worthy confirmation that community science programs can play an important role in monitoring the changing distributions of bumble bees and more.
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 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 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 Conservation of nature's strongholds needed to halt biodiversity loss
(via sciencedaily.com)
Original source 
To achieve global biodiversity targets, conservationists and governments must prioritize the establishment and effective management of large, interconnected protected areas with high ecological integrity, researchers argue in a new essay.
Published Recycling carbon dioxide into household chemicals
(via sciencedaily.com)
Original source 
Scientists report a family of tin-based catalysts that efficiently converts CO2 into ethanol, acetic acid and formic acid. These liquid hydrocarbons are among the most produced chemicals in the U.S and are found in many commercial products.
Published Regional differences in bird diversity in agroforestry systems
(via sciencedaily.com)
Original source 
The diversity and ecological functionality of bird communities in tropical agroforestry systems are shaped by the surrounding landscape, in particular the extent and composition of the forest.
Published Improving statistical methods to protect wildlife populations
(via sciencedaily.com)
Original source 
In human populations, it is relatively easy to calculate demographic trends and make projections of the future if data on basic processes such as births and immigration is known. The data, given by individuals, can be also death and emigration, which subtract. In the wild, on the other hand, understanding the processes that determine wildlife demographic patterns is a highly complex challenge for the scientific community. Although a wide range of methods are now available to estimate births and deaths in wildlife, quantifying emigration and immigration has historically been difficult or impossible in many populations of interest, particularly in the case of threatened species.
Published Powering wearable devices with high-performing carbon nanotube yarns
(via sciencedaily.com)
Original source 
Carbon nanotube (CNT) yarns are promising for flexible and fabric-type wearable materials that can convert waste heat into thermoelectricity. To improve the thermoelectric properties of CNT yarns, researchers dispersed CNT filaments in a highly viscous glycerol, enabling the production of CNT yarn with highly aligned bundles together with surfactants that prevent increased thermal conductivity. This innovative approach can significantly improve carbon nanotube-based thermoelectric materials, making it possible to power wearable devices using just body heat.
Published The impacts of climate change on food production
(via sciencedaily.com)
Original source 
A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.
Published Digging up good news for microbial studies
(via sciencedaily.com)
Original source 
Findings indicate that soil stored under refrigerated or air-dried conditions can still retain the needed information for understanding microbial community composition and structure for many years.
Published Enhancing superconductivity of graphene-calcium superconductors
(via sciencedaily.com)
Original source 
Researchers experimentally investigate the impact of introducing high-density calcium on the superconductivity of calcium-intercalated bilayer graphene.
Published Blueprints of self-assembly
(via sciencedaily.com)
Original source 
Scientists have taken a step closer to replicating nature's processes of self-assembly. The study describes the synthetic construction of a tiny, self-assembled crystal known as a 'pyrochlore,' which bears unique optical properties. The advance provides a steppingstone to the eventual construction of sophisticated, self-assembling devices at the nanoscale -- roughly the size of a single virus.
Published Cloudy waters causes African fish to develop bigger eyes
(via sciencedaily.com)
Original source 
Variations in water quality can impact the development of the visual system of one species of African fish, suggests a new study.
Published Expanding on the fundamental principles of liquid movement
(via sciencedaily.com)
Original source 
We are living in a world surrounded by liquid and flow, and understanding the principles that govern its movement is vital in our high-tech world. Through mathematical modeling and experimentation, researchers have expanded on Tanner's Law -- a law in fluid dynamics that describes how non-volatile liquids move across surfaces -- to cover a wider range of volatile liquids. These findings have the potential to play a role in various liquid-based industries such as electronics cooling.
Published Ukraine war caused migrating eagles to deviate from their usual flight plan, study finds
(via sciencedaily.com)
Original source 
When migrating through Ukraine in 2022, Greater Spotted Eagles were exposed to multiple conflict events that altered their migratory course, according to a new study.
Published Modern plant enzyme partners with surprisingly ancient protein
(via sciencedaily.com)
Original source 
Scientists have discovered that a protein responsible for the synthesis of a key plant material evolved much earlier than suspected. This new research explored the origin and evolution of the biochemical machinery that builds lignin, a structural component of plant cell walls with significant impacts on the clean energy industry.
Published Ion irradiation offers promise for 2D material probing
(via sciencedaily.com)
Original source 
Two-dimensional materials such as graphene promise to form the basis of incredibly small and fast technologies, but this requires a detailed understanding of their electronic properties. New research demonstrates that fast electronic processes can be probed by irradiating the materials with ions first.
