Researchers at Michigan State University discovered that male songbirds use scent to attract both female and male mates through the 'Axe effect'. Female birds preferred the odor of smaller males, while larger males overcompensate with greater amounts of an attractive scent.
A new study published in Biotechnology Journal reveals a cheaper and more efficient method for treating dyed denim, eliminating the need for hazardous sandblasting techniques. The surface activation technique reduces fabric strength decay, shortens wash-down processes, and minimizes chemical usage.
A new study from UCSF found that virtually all pregnant women in the US are exposed to multiple chemicals, including some banned since the 1970s. The study identified over 163 chemicals, with many linked to adverse health outcomes such as preterm birth and childhood morbidity.
Scientists have discovered a key role for the GC-D necklace subsystem in mice's ability to detect safe food based on social scent. This breakthrough adds to evidence that smell is comprised of multiple parts with specialized functions, highlighting a complex communication process between animals through breathing.
Researchers at University of Wisconsin-Madison developed a two-step method to convert cellulose in raw biomass into a promising biofuel. The new process simultaneously bypasses lignin and produces a high yield, making it a promising alternative to fossil fuels.
New study analyzes commercially made carbon nanotubes, finding vastly different compositions and potential emissions of toxic chemicals. Researchers aim to work proactively with industry to prevent environmental mistakes, highlighting the need for better understanding and regulation of nanotechnology manufacturing processes.
Researchers found that acetylcholine enhances visual processing by selectively enhancing information in the brain's visual cortex. This enhancement allows neurons to detect and signal stimuli below detection threshold, a process similar to how attention strengthens signals.
A study by Dutch researchers identified four cases of bronchiolitis obliterans syndrome (BOS) among workers at a chemical plant producing diacetyl, a key component of butter flavoring. The findings support the conclusion that an agent in the diacetyl production process has caused BOS.
A study by Oregon State University researchers identified a soldier beetle preserved in amber, showcasing an ancient chemical defense response. The discovery indicates that this type of protective mechanism has been around for over 100 million years.
A simple oxygen treatment can extend the shelf life of organic produce, reducing losses and costs. This technique has shown promise in preventing scald formation and physiological diseases in apples, with potential applications for other organic fruits and vegetables.
A long-term study found that salamander exposure to atrazine had persistent effects on mortality rates, even after recovery. Survivors of the exposure suffered lower survival rates compared to those not exposed to atrazine.
A new process combines molecular self-assembly with traditional lithography to create multifunctional surfaces in precise patterns. This technique allows for complex patterns of functional monolayers, enabling applications beyond semiconductors.
A new approach eliminates some steps in conventional tanning, resulting in substantial production efficiencies and a significant reduction in pollutants. The reverse process produces comparable leather with 42% less time, 54% fewer chemicals, 42% less energy, 65% less water and up to 79% fewer emissions.
Nanofluidic transistors, the basis of future chemical processors, have been successfully created by researchers. These devices can control fluid flow without moving parts, enabling applications such as cancer diagnosis and biomolecular sensing.
Aplysia sea slugs release an inky secretion that activates feeding pathways in spiny lobsters, stimulating grooming and avoidance behaviors. This novel defense strategy, called phagomimicry, enhances the effectiveness of the slug's escape by distracting the lobster with misleading cues.
McGill researchers identified a link between heat-induced breakdown of amino acids and sugars in food, producing the potential carcinogen furan. Traces of furan have been found in processed and cooked products, particularly canned and bottled foods, but quantities are below considered dangerous thresholds.
Virginia Tech researchers have developed a chemical process to extract ethanol and xylitol from cotton gin residue. This technology has the potential to create a new industry in the state's cotton-growing region, providing a solution to the problem of residue disposal.
A new imaging technique reveals the presence of a previously unknown organelle called a retinosome, which houses retinyl esters essential to the regeneration process. The discovery could lead to better understanding and treatment of congenital blindness caused by defects in the retinoid cycle.
Researchers at NC State University have developed a new process for creating superhydrophobic polymer surfaces that are longer-lasting and more environmentally friendly. By increasing the surface area of a flexible material before attaching coating molecules, they can achieve superior water resistance and durability without using solve...
Scientists at Brookhaven National Laboratory have developed a patented process for encapsulating depleted uranium oxides in thermoplastic polymers, creating a stable and safe material for long-term disposal. The new process also enables the production of radiation shielding and counterweights with low residual radioactivity.
