Adopting some osteopathic traits might help M.D.s boost their patient communication skills

A study found that osteopathic physicians were more likely to use patients' first names, explain medical conditions, and discuss social and emotional impacts of illnesses. Osteopaths also asked patients more questions about their concerns, while allopaths focused on the scientific basis of treatment.

DNA repair activity may be associated with risk of lung cancer

Measuring DNA repair enzyme OGG activity found a significant association with lung cancer risk. Smokers and nonsmokers with low OGG activity had higher lung cancer risk compared to those with normal activity levels, with smokers being at greater risk due to smoking alone.

Office of Naval Research to unveil the 'matchbox' atomic clock

The Office of Naval Research has unveiled a new, ultra-accurate Rubidium atomic clock that is smaller than a matchbox and consumes less power. This tiny clock loses only about one second every 10,000 years, making it ideal for precise ship and aircraft navigation, ground to outer space communications, or missile guidance.

Mouse study gives new view of anthrax toxin

Researchers found no evidence of persistent cytokine increase or link between cytokines and anthrax toxin effects, contradicting earlier beliefs. The study suggests that current efforts to design cytokine-suppressing drugs may be misguided.

Study raises prospect of practical vaccine for metastatic melanoma

A new vaccine has shown promise in stimulating a powerful immune response against melanoma tumors, with 10 patients still alive three years after treatment and no signs of disease in four cases. The vaccine, made using a weakened cold virus, was safe and relatively easy to produce, with minimal side effects.

Bone loss prevention drug showing promise in advanced prostate cancer

A clinical trial found that oral sodium clodronate reduced the risk of symptomatic bone progression by 21% and mortality by 20% compared to placebo, but with limited statistically significant results due to small population size. However, side effects were common, particularly in older patients.

Mouse, stripped of a key gene, resists diabetes

Researchers have discovered an engineered mouse that can eat a high-fat diet without gaining weight or developing diabetes. The mouse lacks the SCD-1 gene, which affects fat production and glucose regulation. As a result, muscle cells are more sensitive to insulin, enabling them to absorb glucose and regulate blood sugar levels.
