Published Chemists image basic blocks of synthetic polymers
(via sciencedaily.com)
Original source 
Researchers have developed a new method to image polymerization catalysis reactions one monomer at a time.
Published New way to count microbes speeds research, cuts waste, could lead to new antibiotics
(via sciencedaily.com)
Original source 
Researchers have developed a new way of counting microorganisms that works as much as 36 times faster than conventional methods, cuts plastic use more than 15-fold and substantially decreases the cost and carbon footprint of biomedical research. The technique could revolutionize the way microbiology experiments are conducted, allowing researchers to test potential new antibiotics in a fraction of the time.
Published Scientists use quantum biology, AI to sharpen genome editing tool
(via sciencedaily.com)
Original source 
Scientists used their expertise in quantum biology, artificial intelligence and bioengineering to improve how CRISPR Cas9 genome editing tools work on organisms like microbes that can be modified to produce renewable fuels and chemicals.
Published Barnacle bends shape to fend off warm-water sea snails on the move
(via sciencedaily.com)
Original source 
Some barnacles are 'morphing' to protect themselves from predatory warm-water sea snails, which are expanding into their territory due to climate change.
Published A breath of fresh air keeps drug-producing cells alive longer
(via sciencedaily.com)
Original source 
Researchers have developed a novel device that produces oxygen inside of a 'living pharmacy' implant in order to keep cells alive inside the self-contained device. The device produses oxygen through a smart, energy-efficient version of water splitting. In new experiments, the novel device kept cells (70-80%) alive for close to a month in low oxygen conditions in vitro, or weeks in vivo.
Published Understanding the dynamic behavior of rubber materials
(via sciencedaily.com)
Original source 
Rubber-like materials can exhibit both spring-like and flow-like behaviors simultaneously, which contributes to their exceptional damping abilities. To understand the dynamic viscoelasticity of these materials, researchers have recently developed a novel system that can conduct dynamic mechanical analysis and dynamic micro X-ray computed tomography simultaneously. This technology can enhance our understanding of the microstructure of viscoelastic materials and pave the way for the development of better materials.
Published Liquid metals shake up century-old chemical engineering processes
(via sciencedaily.com)
Original source 
Liquid metals could be the long-awaited solution to 'greening' the chemical industry, according to researchers who tested a new technique they hope can replace energy-intensive chemical engineering processes harking back to the early 20th century.
Published Greenland's glacier retreat rate has doubled over past two decades
(via sciencedaily.com)
Original source 
A new study documents how Greenland's peripheral glaciers have changed from 1890 to 2022. Using satellite images and a unique archive of historical aerial photos, researchers documented changes in the lengths of more than 1,000 of the country's glaciers over the past 130 years. Although glaciers in Greenland have experienced retreat throughout the last century, the rate of their retreat has rapidly accelerated over the last two decades.
Published Zooplankton in ocean and freshwater are rapidly escalating the global environmental threat of plastics
(via sciencedaily.com)
Original source 
A collaborative research team has recently revealed that rotifers, a kind of microscopic zooplankton common in both fresh and ocean water around the world, are able to chew apart microplastics, breaking them down into even smaller, and potentially more dangerous, nanoplastics -- or particles smaller than one micron. Each rotifer can create between 348,000 -- 366,000 per day, leading to uncountable swarms of nanoparticles in our environment.
Published Feral horses and peatland carbon emissions
(via sciencedaily.com)
Original source 
A ground-breaking new study has found carbon emissions from Australian alpine peatlands to be much higher in areas disturbed by feral horses.
Published A different take on phosphorus: Bacteria use organic phosphorus and release methane in the process
(via sciencedaily.com)
Original source 
Some bacteria are able to tap into unusual sources of nutrients in the surface water of the oceans. This enables them to increase their primary production and extract more carbon dioxide from the atmosphere. In doing so, however, they release the potent greenhouse gas methane.
Published Device 'smells' seawater to discover, detect novel molecules
(via sciencedaily.com)
Original source 
Under the ocean's surface, marine organisms are constantly releasing invisible molecules. Some of the chemical clues reveal which creatures are nearby, while others could be used someday as medications. Now, researchers report a proof-of-concept device that 'sniffs' seawater, trapping dissolved compounds for analyses. The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.
Published The secret to longer lasting batteries might be in how soap works
(via sciencedaily.com)
Original source 
Researchers show that one of the most promising substances for designing longer lasting lithium batteries form micelle-like structures like they do in soap.
Published Machine learning gives users 'superhuman' ability to open and control tools in virtual reality
(via sciencedaily.com)
Original source 
Researchers have developed a virtual reality application where a range of 3D modelling tools can be opened and controlled using just the movement of a user's hand.
Published 'Biodiversity time machine' provides insights into a century of loss
(via sciencedaily.com)
Original source 
AI analysis shows pollution levels, extreme weather events and increasing temperatures devastates biodiversity in freshwater lakes.
Published Experiment shows biological interactions of microplastics in watery environment
(via sciencedaily.com)
Original source 
Scientists have learned over the years that when aquatic organisms such as zooplankton become exposed to microplastics, they eat poorly. Research now shows that their plastic-induced eating difficulties also limit the ability of zooplankton to control algal proliferation. When algae bloom out of control, this presents a problem because some species produce toxins. Also, algal blooms can be associated with pea-soupy, unattractive bodies of water and contribute to hypoxia, a low-oxygen condition that may lead to fish kills.
Published Video technology could transform how scientists monitor changes in species evolution and development
(via sciencedaily.com)
Original source 
New research combines microscope and video technology to analyze how different species develop, and how changes in the timings of any developments can be tracked. A detailed analysis of the Energy Proxy Traits (EPTs) that result from these processes has provided researchers with the first evidence that traditionally measured timings of developmental events are associated with far broader changes to the full set of an embryo's observable characteristics.
Published Two fins are better than one: Fish synchronize tail fins to save energy
(via sciencedaily.com)
Original source 
They say two heads are better than one. But in the world of fish, it appears two fins are better than one. Researchers have produced a theoretical model that demonstrates the underlying mechanisms behind how fish will synchronize their fin movements to ride each other's vortices, thereby saving energy.
Published Brain implant may enable communication from thoughts alone
(via sciencedaily.com)
Original source 
A speech prosthetic developed by a collaborative team of neuroscientists, neurosurgeons and engineers can translate a person's brain signals into what they're trying to say. The new technology might one day help people unable to talk due to neurological disorders regain the ability to communicate through a brain-computer interface.
Published We can save lives and millions with less nitrate in drinking water
(via sciencedaily.com)
Original source 
Denmark could save lives and more than $300 million a year by reducing the amount of nitrate in its drinking water. An ever-growing body of research concludes that the amount of nitrate in some Danish boreholes increases the risk of colorectal cancer.
