This innovative approach has potential to protect against diseases such as tuberculosis, AIDS, and intestinal infections, making it a promising tool for global health threats.
A study by researchers at Washington State University found that corporate social responsibility (CSR) can buffer firms against negative customer reactions following service failures. When CSR aligns with customers' values, it reduces anger and negative word-of-mouth, while increasing positive word-of-mouth and repurchase intentions.
New Caledonian crows exhibit preferences for holding tools on the left or right sides of their beaks due to their unique binocular vision. This adaptation enables each bird to maintain visual control over its tool, with one eye seeing further than the other towards the opposite side of the head.

Research using ultrasound scans distinguishes between yawns and simple mouth openings in fetuses, with more than half of all mouth openings being yawns at 24 weeks gestation. The study suggests that fetal yawning trends may be used to monitor healthy development, possibly related to brain maturation.
New research from Durham University found that over half of mouth openings in fetuses were classified as yawns, suggesting a developmental process linked to fetal health. Yawning declined in frequency after 28 weeks gestation, potentially providing another indicator of the unborn baby's health.
A systematic review of 8 case studies found the 'mother's kiss' technique to be an effective and safe method for removing foreign objects from young children's nasal passages. The technique involves a parent covering the child's mouth and blowing gently, which can dislodge the object without the need for invasive measures.
Researchers discovered that Chinese soft-shelled turtles urinate primarily through their mouths, allowing them to conserve water in brackish environments. This unique adaptation enables the turtles to avoid problems associated with drinking salty water and excreting excess salts.
Researchers sequenced microbial DNA in twins and found salivary microbiomes were not significantly more similar to identical twins as fraternal twins, suggesting genetic relatedness is less important than environment. The study also revealed that the salivary microbiome changes most during early adolescence.
Researchers found that humpback whales use a unique tactic to lunge for krill, beating their tail fins twice as fast as normal and maintaining speed while gliding after opening their mouths. This discovery suggests that lunge feeding may be cheaper than previously thought, but still highly demanding.
A new study reveals that astringent wines and teas can counter the slippery sensation of fatty foods, promoting balance in meal consumption. This opposition between astringent and fat sensations may help maintain dietary diversity.
Hurricane Isaac is expected to bring heavy rain and storm surge to the northern Gulf Coast. The large storm system poses a threat for flooding due to its slow movement over Louisiana, and residents are bracing for the arrival of the hurricane.
Researchers studied how different types of smiling affect stress recovery, finding that Duchenne smiles had the greatest impact on reducing heart rates and improving mood. Smiling may be a simple yet effective way to cope with stressful situations.
Sarah Moore's research finds that analyzing emotional experiences reduces emotions, while analyzing practical experiences amplifies them. For positive experiences, it's best to relive the emotion without rationalizing, while cognitive experiences benefit from analysis and reflection.
Elih Velázquez-Delgado uses X-ray crystallography to discover how nature inactivates caspase-6, a disease-related enzyme. He finds that deleting three specific amino acids reverses the effect and opens a door for developing a drug.
Researchers found that faces are recognized more by their features than the entire face, contradicting the long-held belief in holistic processing. This study may help understand rare facial recognition disorders.
Researchers analyzed fatty acid composition and DNA analysis to identify the source of US-grown pine nuts. Most samples found to be mixtures of different species, but combining these methods didn't definitively link to 'pine mouth',
A new study found that smoking disrupts a healthy balance of bacteria in the mouth, making smokers more susceptible to gum disease and other oral health issues. The researchers suggest that dentists should offer more aggressive treatment for smokers and encourage them to quit.
Researchers found that Malaysian Chinese use a unique mixed strategy to recognize faces, focusing on the eyes and nose more than the mouth, which proved advantageous for accurate recognition of Chinese and Caucasian faces.
Research found that women adapt their brain function to recover from facial paralysis better than men, with improved spontaneous smile recovery and longer functional recovery periods. The study, involving 114 patients, highlights the relevance of patient gender in planning facial paralysis reconstruction strategies.
A new study in the Journal of Consumer Research reveals that people who share sensory experiences, such as enjoying a cupcake, tend to dampen their emotions and are less likely to spread word-of-mouth opinions about them. In contrast, sharing practical experiences, like using a USB stick, increases understanding and enthusiasm.
A new study found that graphic cigarette package warning labels, including images of lung and mouth cancer, can significantly reduce demand for cigarettes. The experimental auction involved 404 adult smokers from four states, who bid on packs with different kinds of warning labels.
Scientists have observed three stages of bioelectric activity that shape the developing face, including a wave of hyperpolarization that marks eye formation and gene expression domains. Disrupting this signaling can lead to craniofacial abnormalities.
A USC study reveals that empathetic responses are generated by both the sensory-motor and rationalizing parts of the brain. The research found that even individuals with physical differences can understand pain in a different limb due to automatic brain processes.
Researchers found a correlation between FAP and abnormal blood vessel density in the oral mucosa, suggesting a potential screening test. The study used a device to measure vascular density in patients with FAP and controls, showing higher values in FAP patients, which could indicate an alternative marker for colon cancer risk.
A new study provides experimental evidence supporting Darwin's phylogenetic limiting similarity hypothesis, where closely related species are more prone to extinction. The research found that competitive exclusion occurred more frequently and rapidly between closely related microorganism species.
A study found that patients with Sjögren's syndrome are more likely to experience difficulty identifying and describing emotions (alexithymia), which is associated with poorer mental wellbeing. The inability to cry may also contribute to this issue, as patients rely on words and facial expressions instead of tears.
A new review challenges the idea that holistic processing comes with expertise, finding that both novices and experts use holistic processing for different reasons. Researchers tested people in music, Chinese characters, and face recognition, revealing strategic and automatic processing.
Fusobacterium nucleatum, a common oral bacteria, facilitates disease and infection spreading from the mouth through the bloodstream. This bacterium is linked to increased risk of pregnancy complications, including miscarriage, preterm birth, and stillbirth.
A low pressure area known as System 99S is strengthening in the Timor Sea, just 20 miles from Darwin, Australia. Forecasters predict the system will become a tropical depression or storm due to warm ocean surface temperatures.

New 3D modeling of Anomalocaris' mouth parts reveals they were flexible, not hard like teeth. This challenges the long-held idea that it preyed on trilobites with hard shells. The investigation also found no signs of wear on the mouth parts, which further supports a soft-food diet.
Researchers found that bacteria from the mouth and gut can enter the body and contribute to inflammation and plaque rupture in atherosclerosis. The study identified specific bacteria, such as Pseudomonas luteola and Chlamydia pneumoniae, which were present in both atherosclerotic plaques and the mouths and guts of patients.
