A new study by CU-Boulder found that trees with smoother bark can repel mountain pine beetles more effectively. The researchers tested how well the beetles could cling to different bark textures and found that only 21 of 22 beetles could stick to rough bark, while all fell off smooth bark in under a minute.
Researchers at the American Dental Association's Anthony Volpe Research Center have received a $2.2 million grant to develop new resin composite dental fillings. The goal is to create self-healing systems that can significantly extend the life of composites, addressing the issue of current materials degrading over time.
The largest and oldest ancient wine cellar in the Near East has been discovered in northern Israel, containing 40 jars of strong, sweet wine dating back to around 1,700 B.C. The team found molecular traces of key wine-making ingredients, including honey, mint, and resins, indicating a consistent recipe was followed in each jar.
Scientists analyzed 538 amber samples to reconstruct ancient atmospheric compositions, finding that oxygen levels were significantly lower than today. This suggests a link between low oxygen and high carbon dioxide concentrations, which may have influenced climate and life evolution.
Researchers have developed a new resin that can be molded into complex, highly conductive 3-D structures with features just a few micrometers across. The resin holds promise for making customized electrodes for fuel cells or batteries, as well as biosensor interfaces for medical uses.
A new study has provided detailed knowledge of the resin secretory system in Boswellia trees, revealing a 3-D network of inter-connected canals that allow for efficient transport of resin. This discovery could lead to improved tapping techniques, reducing damage to trees and ensuring their long-term survival.
Researchers found a 100 million-year-old fossil of an ancient spider attacking its prey caught in its web. The discovery provides the oldest evidence of social behavior in spiders and offers a unique glimpse into the distant past.
Research from North Carolina State University reveals that honey bees increase propolis collection by 45% when infected with harmful fungi, providing a natural antifungal agent to protect their colony. The bees also physically remove infected larvae to prevent fungal spores from spreading.
A study by University of Cincinnati researchers found that stainless steel- and/or co-polyester lined-aluminum bottles did not release BPA, while aluminum bottles with epoxy-based resins showed variable contamination. However, boiling water increased BPA migration from epoxy-lined bottles.
Researchers from NC State University have designed a sensor that can measure strain in structural materials and heal itself when broken. The sensor, which uses infrared light to detect changes in length, contains a UV-curable resin that hardens upon damage, allowing it to repair automatically.
Researchers used X-ray computed tomography to create stunning three-dimensional images of the fossilized spider, revealing it as a member of the Huntsman spiders genus. The study demonstrates that historical pieces of darkened amber can yield vital data when studied by modern techniques.
A new type of matting developed by ECOPROMAT project uses natural materials to create an environmentally-friendly solution for protecting against contagious animal diseases. The matting is highly absorbent, biodegradable, and affordable, making it a significant cost-saving alternative to synthetic mats.
The University of Montreal has received $1.6 million in new funding to advance healthcare research over the next three years. The funding will support various collaborative health research projects across multiple disciplines, including physics, pharmacology, chemistry, and dentistry.
A review by the American Society of Nephrology suggests that ion exchange resins used to treat hyperkalemia may not be effective and could be harmful. The authors recommend further studies on these products and urge doctors to explore alternative treatments first.
Researchers from the University of Valencia confirm pine resin was used to seal a 2,000-year-old amphora found in Morocco. The vessel contained metallic fragments likely used for iron-working, suggesting it may have been reused as a protective container.
A UCLA research team will develop an ultra-high-toughness nanomolecular resin to reinforce asphalt-aggregate mixture, providing mechanical locking of aggregates and serving as a load-bearing component. The new repair methodology aims to enhance the strength, durability and service life of asphalt pavements.
In 1932, chemist Charles Holmes Herty discovered a method to create high-quality white paper from rapidly renewable southern pine trees, sparking a massive pulp and paper industry in the southeastern US. This led to thousands of new jobs, billions of dollars in economic growth, and the preservation of old-growth forests.
Researchers have fabricated microscopic polymer beads that change color instantly in response to external magnetic fields. The beads exhibit excellent structural stability and are compatible with various dispersion media, allowing for tunable colors in different chemical environments.
Researchers at Fraunhofer-Gesellschaft develop a measuring technique to monitor resin distribution during OSB production. The new method uses special optics to record the image of the shavings mat, allowing for continuous measurements during production.
Researchers at the Naval Research Laboratory have successfully produced carbon nanotubes in high yields using commercially available aromatic containing resins. The method enables the production of MWNTs in moldable solid forms, films, and fibers with varying amounts of nanotubes and amorphous carbon.
Researchers at the University of Florida and Berlin Museum found that prehistoric aquatic insects were trapped in resin flowing into swamps, becoming fossilized in amber. This discovery sheds light on prehistoric ecosystems and may help recreate ancient water environments.
A team of scientists at the University of Manchester found evidence that ancient Egyptian physicians practised a credible form of pharmacy and medicine over 1,000 years before Hippocrates. The researchers discovered medicinal remedies such as honey, resins, and metals with therapeutic merit, many of which remain in use today.
New nanocomposites may mean more durable tooth fillings, according to scientists at NIST. The researchers' technique solves a problem with standard composite resin fillings by producing stronger and more effective restorations.
The production of frankincense is declining in the Horn of Africa due to intensive tapping, which diverts carbohydrates from reproductive organs. The study suggests that less intensive tapping procedures and rest periods are needed to ensure sustainable production.
