Transposons are DNA sequences that have the potential to move to new positions within the genome. Their mobilization in the genome of eggs and sperm can lead to infertility. An RNA-based defense system, the Piwi-interacting RNA (piRNA) pathway, is responsible for the suppression of transposons. A new study has advanced understanding of how Piwi fends off jumping genes.

Intestinal infection from parasites has been recognized as a global health problem that can be particularly harmful to children under 5 years of age, with a greater prevalence of infection in developing countries. New research is showing that some bioactives, including oregano oil, may offer help.

Scientists from Philip Morris International (PMI) have presented details of a series of advanced techniques for the in vitro toxicological assessment of complex mixtures.

Researchers and engineers have long sought ways to conceal objects by manipulating how light interacts with them. A new study offers the first demonstration of invisibility cloaking based on the manipulation of the frequency (color) of light waves as they pass through an object, a fundamentally new approach that overcomes critical shortcomings of existing cloaking technologies.

Millions of lipid panels, blood tests that look at cholesterol levels as well as triglycerides, are performed each year, and are key to assessing risk for heart disease. New studies suggest current tests, which measure the abundance of lipid classes, are insufficient and should be replaced by tests to identify lipids at the individual species level.

Physicists are on the hunt for nitrogen containing molecules in space. Using terahertz spectroscopy, they directly measured two spectral lines for one particular molecule for the first time. The discovered frequencies are characteristic of the amide ion, a negatively charged nitrogen molecule.

The lab will run full-service testing for cannabinoid profiles, terpenes, pesticides, heavy metals, biological screening, and residual solvents, testing for 10+ cannabinoids and 40+ terpenes.

Washing your hands and cleaning your house frequently may help to lower your contact with common flame-retardant chemicals, according to a new study.

Researchers have identified the genetic structure of the Painted Bunting, a neotropical migratory songbird, using microsatellite DNA and single nucleotide polymorphisms to develop high-resolution markers to differentiate between individual birds, enabling identification of individual birds and migratory patterns.
