A recent study found that areas with greater biodiversity of small mammals have lower rates of Lyme disease. This is due to a decrease in the number of infected tick nymphs, which are most active during summer and hard to detect.
Researchers are using focused microwave radiation to heat and kill breast cancer cells, achieving significant tumor shrinkage in clinical trials. The technique uses high water content in cancer cells to deliver precise heat damage.
Researchers suggest that early life forms could have emerged from heterogeneous lipid assemblies, with information stored in composition rather than sequence. This model offers a solution to the long-standing question of how lipid assemblies could carry and propagate information.
Astronomers use Chandra to study a cloud of gas in NGC 4151, blown away from the black hole at incredible velocities. The observation shows how massive black holes disrupt their surroundings over vast distances.
Future orbiting X-ray telescopes will detect iron emissions in accretion disks around giant black holes, confirming their spin rates. This new telescope system could reveal the variability of X-ray emissions and test Einstein's theories on general relativity.
A study by University of North Carolina at Chapel Hill found that US adolescents are physically inactive due to limited access to school physical education programs and community recreation centers. High-crime neighborhoods also contribute to a sedentary lifestyle, increasing the risk of obesity and poor health.
A UCSD researcher has been awarded a grant to study the incidence and impact of microsatellite instability on colon cancer in African-Americans. The research aims to understand why African-Americans have a higher death rate from colorectal cancer despite lower incidence rates.
A Phase I study of aerosolized administration of tgAAV-CF showed efficient gene transfer throughout the upper airways of patients with mild CF lung disease. No neutralizing antibodies were detected, suggesting a good safety profile for further development.
Scientists at Purdue University have developed a simple and quick method to assess environmental cleanup efforts using genetics. The technique detects genes that reveal the presence of an enzyme produced by pollution-busting bacteria, allowing for real-time monitoring of soil cleanup progress.
The proposed food label changes could lead to a reduction in heart disease deaths, with estimated annual savings of $25 billion to $59 billion in healthcare costs. Manufacturers are expected to reformulate products in response to consumer demand for lower trans fat foods.
Astronomers have directly detected a new type of stellar flare on the binary system HR 1099, challenging current models and providing insight into flare physics. The flares were observed in a narrow temperature range of gas on the star, distinct from the hot gas that emits X-rays.
Researchers identified two natural human antibodies that restored myelin sheath and promoted nervous system repair in mice with demyelinating diseases. The discovery holds promise for developing new treatments for conditions like multiple sclerosis.
A new OHSU study shows 54% of family members reported moderate or severe pain for dying patients in the last week of life, a sharp increase from 1997. Researchers attribute possible explanations to changes in pain treatment options and physician prescribing practices.
Researchers found that men who ate two servings of high-fiber cereal per day made spontaneous changes to their diets, reducing fat intake and increasing fiber consumption. The study suggests that high-fiber cereal can be an easy way for Americans to improve their diet and reduce their risk of heart disease.
A study by Cornell University researchers suggests that prenatal cocaine exposure may cause lasting attention dysfunction in children, impacting their ability to focus despite distractions. The findings support the potential long-term effects of cocaine use during pregnancy on children's cognitive development.
Targeted Genetics Corporation has shown promise in its AAV gene therapy program for rheumatoid arthritis (RA), reducing ankle and hind paw swelling in preclinical studies. The treatment uses a recombinant TNFR:Fc fusion protein, which antagonizes the function of TNF-a, a key component of the inflammatory response.
The MIT robot significantly improved patients' recovery of arm movement in a clinical trial involving 56 stroke victims. The robot provided adjustable levels of guidance and assistance to facilitate patients' arm movements, resulting in twice as high scores on tests measuring increased movement.
A University of Maryland School of Medicine researcher analyzed 23 clinical studies involving prayer, non-contact therapeutic touch, and other unconventional spiritual interventions. The studies showed a positive impact on patients in 57% of cases, with benefits including less pain and faster recovery times.
The European Society of Human Reproduction & Embryology conference in Bologna, Italy, presented groundbreaking research on preimplantation diagnosis, cancer risk factors, and assisted reproductive techniques. The event also explored new technologies, such as keyhole surgery and laser-assisted IVF.
Researchers have identified a sequence of amino acids found in fibronectin that accelerates healing of hard-to-treat skin wounds in obese, diabetic mice. The substance completely healed skin puncture wounds in eight days, compared to 20-42 days in untreated diabetic mice.
