The science has long been clear that smoking causes cancer, but new research shows that children could inherit genetic damage from a father who smokes. Canadian researchers have demonstrated in mice that smoking can cause changes in the DNA sequence of sperm cells, alterations that could potentially be inherited by offspring.

Scientists have described the function and the possible mutations of a gene implicated in this Fanconi anemia that affects functions like nerve and skeletal development, blood cell formation and predisposition to cancer. This discovery will aid in detecting the defective gene that causes Fanconi anemia, which is fundamental in prenatal diagnosis and even pre-implantation diagnosis.

A major focus on the study of Einstein’s theory of general relativity has been on confirming the existence of the gravitomagnetic field, as well as gravitational waves. A physicist recently argued in a paper that the interpretation of the results of Lunar Laser Ranging, which is being used to detect the gravitomagnetic field, is incorrect because LLR is not currently sensitive to gravitomagnetism and not effective in measuring it.

A new test for diagnosing TB offers a quick and simple alternative to existing three-day methods, according to a new article. The study shows that the test, which involves taking three sputum samples from a patient over the course of one day, is just as effective as other more invasive and complicated testing methods, which take three days.

Researchers report their findings from the first-ever study examining the prognostic value of serum HBV DNA levels for patients with liver cancer undergoing chemotherapy. They found that patients with high pre-chemotherapy levels of HBV DNA had a significantly increased incidence of severe hepatitis which was associated with the worst survival.

The first study in the developing world of directly observed antiretroviral therapy for HIV-infected children shows this form of treatment is an inexpensive, effective way to ensure that children take life-saving medications. Without antiretroviral treatment, half of all HIV-infected children die by age 2. With therapy, however, many children survive to adulthood.

Scientists are investigating ways to boost the survival rates of fish caught and then released by anglers. Guidelines designed to improve fish survival were recently developed for released line-caught snapper, silver trevally, mulloway, sand whiting, yellowfin bream and dusky flathead.

Broccoli, eggplant, cabbage and capsicum grown with compost made from recycled garden offcuts have produced equivalent yields to those cultivated by conventional farm practice, but without the subsequent build up of phosphorus. Scientists have found very high levels of phosphorus and low levels of organic carbon in vegetable growing soils, during a major research project designed to help vegetable growers significantly improve soil quality and productivity.
