Researchers have identified 26 species of bacteria in the human gut microbiota that appear to be linked to obesity and related metabolic complications. These include insulin resistance, high blood sugar levels, increased blood pressure and high cholest…
Squishy models are anything but child’s play as they help researchers understand the building-block nature of proteins.
Pathogens can slip through leaf pores and begin infecting a plant. However, new research shows that this invasion is halted when a beneficial bacterium is present in the soil where the plant is rooted.
Pity the male of the marine whelk, Solenosteira macrospira. He does all the work of raising the young, from egg-laying to hatching — even though few of the baby snails are his own. Throw in extensive promiscuity and sibling cannibalism, and the specie…
Scientists have established a genetic mouse model for primary ovarian insufficiency (POI), a human condition in which women experience irregular menstrual cycles and reduced fertility, and early exposure to estrogen deficiency. POI affects approximatel…
Scientists have discovered several thousands new genetic variants impacting gene expression some of which are responsible for predisposition to common diseases, bringing closer to the biological interpretation of personal genomes.
The predictive power of invasive species hypotheses has declined over time, presenting a challenge to policy makers and resource managers who rely on accurate risk assessment – so reports a team of international scientists. The study was published in…
Algae are high on the genetic engineering agenda as a potential source for biofuel, and they should be subjected to independent studies of any environmental risks that could be linked to cultivating algae for this purpose, two prominent researchers say.
The cytomegalovirus (CMV) is a member of the herpesvirus family. Although most people carry CMV for life, it hardly ever makes them sick. Researchers have now unveiled long term consequences of the ongoing presence of CMV: later in life, more and more …
Scientists have developed a way to switch fluorescent molecules on and off within aqueous environments, by strategically trapping the molecules inside water-soluble particles and controlling them with ultraviolet light.
The hawkmoth, a natural petunia pollinator, spends less time on Petunia lines that offer less nectar as a reward.
Pathogens can slip through leaf pores and begin infecting a plant. However, new research shows that this invasion is halted when a beneficial bacterium is present in the soil where the plant is rooted.
