A recent study found that proteins in alligator blood have potent antimicrobial properties, effective against MRSA and Candida albicans yeast infections. Researchers believe these proteins could be used to develop new treatments for diabetic ulcers, severe burns, and other infections
A recent study published in Nature Medicine found that fetal cells implanted in patients with Parkinson's disease can develop Lewy body pathology, a defining characteristic of the disease. The study suggests that cell replacement strategies for Parkinson's disease may not be effective in the long-term.
A study analyzing brain tissue of volunteers found that small vessel disease accounted for 33% of dementia risk, while Alzheimer's treatments remain investigational. Researchers suggest reducing hypertension and diabetes as effective ways to mitigate this risk.
A new study by the University of New South Wales reveals that contaminated seaweeds in Sydney Harbour are killing up to 75% of small crustacean offspring. The harbour's seaweeds have been found to contain high levels of copper, lead and zinc, posing a threat to marine life.
Researchers warn of unforeseen environmental and health consequences of nanosilver in consumer products, as simple experiments show nanoparticle silver can leach into waterways. Improved product labeling is proposed to increase public awareness.
Scientists suggest that meteorite impacts may have delivered the chemical seeds of life on Earth, resulting in a predominance of left-handed amino acids. This theory is supported by evidence found on meteorites and simulations of prebiotic conditions, which show that cosmic amino acids can transfer their chirality to simple amino acids.
Scientists have identified 20 new regions of the genome linked to human height, adding to the growing understanding of genetics and growth. These discoveries may shed light on diseases such as osteoarthritis and cancer, and could lead to new avenues for treating various conditions.
A new study found that rats fed tart cherry powder on top of a high-fat, Western-style diet had lower body weight, fat mass, total cholesterol, triglyceride, TNF-alpha, and IL-6 levels. These findings suggest a potential link between tart cherry consumption and reduced cardiovascular risk factors.
A study of 36 freshmen at Auburn University found that students gained an average of 1.9 pounds during the first semester and 4.8 pounds for the entire freshman year, with some losing weight altogether.
Researchers have identified at least three clays that kill or significantly reduce the growth of MRSA, Mycobacterium ulcerans, E. coli, and Salmonella bacteria. The clays' antibacterial activity is believed to be due to specific compounds within them.
Researchers have developed solutions to improve bamboo fabrics' durability and hygiene, making them more suitable for consumer products. The new treatments significantly reduce bacterial growth and increase UV protection, opening doors for eco-friendly clothing options.
Researchers at Howard Hughes Medical Institute identified functional mutations in three genes that contribute to blood pressure variation in the general population. These mutations, present in approximately 2% of the population, are associated with a 60% reduction in the risk of hypertension.
Researchers are now exploring the fringes of the Periodic Table in pursuit of another 'island of stability', similar to the one discovered in superheavy chemical elements. The next island could lie around atomic number 164, requiring more sophisticated technology and a deeper understanding of element formation.
Researchers at Virginia Tech have found that citric acid can control the clumping of buckyballs, forming sphere-shaped aggregates. However, the long-term implications of this finding are uncertain, with concerns about potential toxicity and environmental impact.
A study by physiologists at Ball State University found that daily dosages of ibuprofen and acetaminophen increased quadriceps muscle mass and strength gained during three months of weight lifting. The findings suggest a positive effect on the metabolic response to resistance exercise, allowing for enhanced protein synthesis in muscle.
An autopsy study of 3,400 individuals found that small vessel damage accounts for 33% of dementia risk, surpassing Alzheimer's and Lewy Body diseases. This discovery underscores the importance of controlling hypertension and diabetes to protect brain health.
Animal research in monkeys shows that treating with amphetamine reduces self-administration of cocaine for up to a month by about 60 percent. The study demonstrates the feasibility of using amphetamine-like drugs to treat cocaine addiction.
Researchers at Yale University have discovered that rare genetic variants can be associated with a significantly lower risk of developing high blood pressure. The study found that individuals carrying one defective copy of a gene had a 60% lower risk of developing hypertension by age 60 compared to the general population.
A new test can detect gunshot residue on a single speck of gunpowder smaller than the width of a human hair, boosting accuracy and reducing false positives. The test uses solid phase micro-extraction combined with gas chromatography to identify chemical compounds present in the powder.
Researchers at Wake Forest University found that environmental enrichment and increased social stress can reduce cocaine self-administration in monkeys. The study showed that subordinate animals, who experience more stress, consume more cocaine than dominant animals with improved living conditions.
A study found that subordinate monkeys showed pronounced decreased brain activity in areas involved with stress, anxiety, reward, and emotion when faced with a stressful situation. In contrast, dominant monkeys were less likely to choose cocaine after the same encounter.
