Furan fatty acids have been found to exist in all samples of rubber tree latex, with varying concentrations. The study identifies specific genotypes with high FuFA content, offering potential for enhanced economic value and sustainability.
Scientists at Ohio State University have developed efficient extraction methods for natural rubber-producing plants, including a dandelion species and a desert shrub. The new techniques improve latex yield and reduce environmental footprint, offering an alternative to the world's primary natural rubber supply in Southeast Asia.
A French team of researchers has developed a method to produce stable polystyrene dispersions with unprecedentedly large and uniform particle sizes. The team used light-driven processes, overcoming the previous 300-nanometer ceiling limit of UV and blue-light-based photopolymerization systems.
Researchers from Shinshu University develop a novel polymer interlocking mechanism to produce tough and additive-free latex films. The rotaxane-based strategy results in unusual crack propagation behavior, increasing tear resistance and preserving flexibility.
In the Brazilian Amazon, small towns are practicing a self-sustaining circular economy by converting waste into inputs for production. The Carauari community produces 100 metric tons of processed fish per year, generating resources from waste that fuel other activities.
Researchers have developed a biodegradable polymer coating that can block grease and oil in compostable paper packaging, reducing environmental impact. The coating's ester linkages break apart in water, allowing microorganisms to degrade it.
Researchers at RIT developed MathDeck, an online search interface that allows anyone to easily create, edit, and lookup sophisticated math formulas. The math-aware search interface uses image processing and machine learning techniques to recognize formula images and hand-drawn symbols.
Research suggests previously unrecognized latex allergies could play a role in equine asthma. Studies applied microarray platforms to determine precise allergens within stable dust that elicit the condition. Latex proteins were found among the most significant allergens associated with equine asthma, alongside Aspergillus fumigatus.
A moth caterpillar uses acids and scraping behaviors to disable latex defense systems in poinsettia plants, allowing it to feed safely. This unique strategy is thought to have evolved as a result of co-opting an existing anti-predator deterrent.
A recent study by the University of the Basque Country highlights the importance of standardizing thickeners for people with dysphagia. The research found significant gaps in current guidelines, leading to concerns over food safety and swallowing difficulties.
A team of MIT researchers has designed a breathable workout suit with ventilating flaps lined with live microbial cells, which can be engineered to sense and respond to humidity. The suit effectively removes sweat from the body and lowers skin temperature, providing a cooling sensation.
A single sesquiterpene lactone, taraxinic acid β-D-glucopyranosyl ester (TA-G), found in dandelion latex, negatively affects cockchafer larvae growth. This compound plays a crucial role in dandelion defense against root feeders.
Researchers discovered that skin can communicate with the liver, affecting metabolism and fat accumulation. Covering skin with a substance like vaseline or latex prevents heat loss, which leads to reduced fat accumulation in the liver.
A study of 13,000 adults in Sweden, Norway, Denmark, Iceland, and Estonia found that plumbers and spray painters were at high risk of developing new-onset asthma due to workplace exposure. The study identified high-risk substances and occupations, highlighting the need for primary prevention measures.
Using powder-free latex gloves significantly reduced the rate of latex sensitization among healthcare workers. A study found a 16-fold reduction in latex sensitization after institutions switched to powder-free gloves, preventing allergic sensitization and allowing some sensitized workers to lose sensitivity.
Scientists at Eindhoven University of Technology have developed a new transparent, conducting film made from commonly available materials, offering a rare metal-free alternative to indium tin oxide. The material, produced in water, has an important advantage over ITO: it is environment-friendly and suitable for flexible displays.
Researchers found milkweed plants have declined in three key defense traits against caterpillars, such as hairs, cardenolides and latex, but increased ability to regrow. This evolutionary trend may be an energy-efficient response to counter caterpillar attacks.
Researchers at the University of Warwick developed a new method to create fire-resistant and hard-wearing latex emulsion paints by coating polymer particles with nanosized Laponite clay discs. This technique improves the paint's performance, enabling the creation of compact yet highly sensitive sensors.
A large international study found that nurses are more than twice as likely to develop occupational asthma and cleaners face a 71% higher risk. Workplace conditions may be responsible for up to 25% of new asthma cases in industrialized countries.
A recent UK study found that one third of food packaging tested contained latex, with transferable amounts causing severe reactions. The lack of labelling poses a significant risk to individuals with natural rubber latex allergies, who can be exposed to deadly levels of the allergen.
A study by Emory University Health Sciences Center found that many young men have trouble using condoms correctly, with errors including not checking expiration dates and putting on condoms during sex. The research emphasizes the importance of providing adequate condom use education to prevent HIV and other STDs.
Jan Lohmann and Thomas Bosch report a discovery of the novel peptide HEADY, which acts as a potent inducer of head formation in lower metazoans. Grafting experiments show that HEADY induces a secondary head in Hydra tissue, revealing its role as a developmental switch for axis specification.
Researchers at the University of Delaware have created a porous, rainbow-colored metal that acts like a prism, diffracting a spectrum of colors. The material's tiny holes are 20,000 times smaller than existing metal meshes and could be used to steer light in photooptic computer components.
Researchers from the University of Delaware have developed a cheap and disposable biosensor using gold-on-plastic technology, which can detect targeted molecules in bodily fluids with high accuracy. The device is more specific than existing methods, such as latex agglutination tests, and can be produced at a lower cost.
Researchers created a topical hand cream that prevents two common latex allergy reactions, sensitization and contact dermatitis. The cream's zinc gel composition forms a protective matrix on the skin's surface, binding soluble latex proteins and other irritants to prevent allergic responses.
