A new study reveals that many laboratories offering genetic tests for cystic fibrosis don't test for enough mutations, which can lead to unreliable results. The recommended widespread screening is premature due to the lack of standardization in testing labs.
Kevin krajick's winning entry, 'The Crystal Fuel', reported on the discovery of methane hydrate crystals and their potential to contain twice the energy of Earth's coal, oil, and gas reserves. The article sparked significant interest in this relatively new area of research.
A new Alzheimer's disease treatment, metrifonate, has been shown to improve behavioral disturbances and mental performance in patients with mild-to-moderate dementia. The study found that metrifonate slowed the mental decline associated with Alzheimer's disease over a six-month period.
Researchers have found that Sulfolobus acidocaldarius exhibits a very high rate of genetic recombination, with 95% of mutations producing recombinants. This suggests an alternative mechanism of DNA repair beyond classical recombination, which may be driven by the microbe's exposure to oxidative stress.
Three experts recommend establishing a national office of drug safety to track and reduce prescription drug-related injuries, which could be the fourth-leading cause of death in the US. The proposed office should develop reliable estimates of deaths and serious injuries from prescription drugs.
A new chemistry analysis reveals the optimal time for harvesting pungent peppers, with Piquin peppers requiring 40 days and De árbol and Habañero peppers needing 50 days. The hot flavor of chile peppers is caused by capsaicinoids, which degrade over time due to naturally-occurring compounds called peroxidases.
Astronomers used an instrument to collect light from 1000 objects, discovering seven compact blue galaxies beyond 2 billion light years away
A bacterial pesticide, Burkholderia cepacia, has raised concerns over its potential to cause deadly lung infections in people with cystic fibrosis. Experts are calling for a ban on its use in pest control until it is proven safe.
A new test measuring free PSA can accurately identify men at risk of prostate cancer, allowing for targeted biopsies and reducing unnecessary procedures. The test aims to cut the cost of prostate screening dramatically while sparing men from potential complications like infection and bleeding.
