Mutations from Venus, mutations from Mars

Researchers at Weizmann Institute of Science discover that genetic mutations affecting only half the population, like those causing male sterility, occur twice as often as those affecting males and females equally. This finding has implications for understanding causes of genetic diseases and developing targeted treatments.

R.I. lead law effective, often ignored

A study by Brown University researchers found that Rhode Island's Lead Hazard Mitigation Law has significantly reduced blood lead levels in children living in compliant buildings. However, only 20% of properties covered by the law were in compliance, with average lead levels still above 5 micrograms per deciliter in noncompliant homes.

Lab monitoring tests not always ordered per recommendations

A study found that lab monitoring tests are not always ordered as recommended, with factors such as specialist status, age, and general health influencing the use of these tests. The research suggests that interventions to improve laboratory monitoring should focus on areas with the greatest potential for improvement.

Screening for autism: There's an app for that

Researchers at Duke University have developed software that tracks and records infants' activity during videotaped autism screening tests. The program is as good as experts giving the test themselves and better than non-expert medical clinicians and students in training, showing promise in identifying early signs of autism.
