Researchers found that smallpox vaccine-induced antibody immunity can last a person's entire life, while T-cell immunity declines slowly over time. The study also showed that repeated vaccinations have little impact on immunity levels.
Researchers used data on recent SARS cases to project how the epidemic will proceed under various circumstances. They found that careful interventions, such as reducing contacts and improving treatment, can control the spread of the virus.
A study of 487 cocaine-dependent patients found that treatment combining group drug counseling with individual therapy reduced HIV risk. The combination treatment showed the best improvements in reducing cocaine use, resulting in a 40% decrease in HIV risk.
The Chamorro people's consumption of cycad-fed flying foxes may have led to high incidence of ALS-PDC, a neurodegenerative disease. Studies show that eating wild animals with unknown health risks can be particularly hazardous.
Researchers estimate between 2 and 100 million global species, developing six methods to assess biodiversity in a single habitat. Three methods proved effective even with limited data, while spacing ecoregions evenly throughout the continent yielded the best results.
A recent study found that monogamous mammals are more likely to die out due to factors such as population isolation and smaller harems, which can lead to lower male populations and reduced ability to detect approaching hunters. Conservation efforts may need to be targeted towards these species to save them from extinction.
A recent study found that non-destructive fishing methods on the Banggai cardinalfish population reduced group size by half. This threat is alarming, given the species has been commercially fished for only six years and its range expands widely. To mitigate this, researchers encourage local people to raise Banggai cardinalfish in aquar...
Smoking prevalence varies significantly among immigrant groups and countries of origin. Native-born respondents had higher smoking rates than foreign-born respondents. Including findings on country of origin can enhance the development of culturally sensitive smoking cessation programs.
The Clemson Inflatable Fabric Airlock, developed in collaboration with NASA, boasts a two-layer fabric design that eliminates seams for added strength. The airlock has withstood a terrestrial tensile force of over 675,000 pounds at four atmospheres of internal pressure.
Bacteriophage, or phage, previously thought not to be infectious to humans, may be a new target for fighting certain bacteria that produce toxins. Scientists found that phage can transfer toxins and genes between bacteria, transforming harmless microbes into virulent bugs.
A study of 53 African-American adults with a history of cocaine use found that 45% had elevated serum CRP levels, associated with subclinical coronary atherosclerosis and cardiac abnormalities. Elevated CRP may indicate future cardiovascular events.
A recent study establishes that rapid infant weight gain is associated with obesity in young adulthood, particularly among African Americans. The study found that subjects with rapid early infancy weight gain were more than twice as likely to be obese at age 20 compared to those without rapid weight gain.
The Field Museum has received a grant to preserve and conserve its extensive collection of Chinese textiles, featuring 1,200 embroidered folk textiles and 1,000 historical costumes. The museum's unique holdings provide valuable insights into traditional Chinese textile decoration techniques and symbolism.
A study published in Nature found that behavioral treatment can reverse brain changes caused by cocaine use and prevent relapse. Rats given extinction training during withdrawal showed a significant increase in glutamate receptors, which may help ease cravings and prevent relapse.
A study tracked 148 HIV-infected individuals aged 25-69 to determine factors influencing adherence to antiretroviral medication. Patients over 50 were more likely to adhere to their regimen, with 53% meeting the standard compared to 26% of younger patients.
Emory University researchers have successfully self-assembled Alzheimer's amyloid fibrils into well-defined nanotubes. These nanotubes exhibit unique properties and can be used to build nanotechnological devices, offering new avenues for research and potential applications in fields such as medicine and materials science.
